These final regulations provide guidance on the application of
sections 162(a) and 263(a) of the Code to amounts paid to
acquire, produce, or improve tangible property. They also pro-
vide guidance under section 167 regarding accounting for and
retirement of depreciable property, and under section 168 re-
garding accounting for property under the Modified Acceler-
ated Cost Recovery System (MACRS) other than general as-

Introduction
The Internal Revenue Bulletin is the authoritative instrument of
the Commissioner of Internal Revenue for announcing official
rulings and procedures of the Internal Revenue Service and for
publishing Treasury Decisions, Executive Orders, Tax Conven-
tions, legislation, court decisions, and other items of general
interest. It is published weekly.
It is the poli
cy of the Service to publish in the Bulletin all sub-
stantive ru
lings necessary to promote a uniform application of
the tax laws
, including all rulings that supersede, revoke, mod-
ify, or amen
d any of those previously published in the Bulletin.
All publish
ed rulings apply retroactively unless otherwise indi-
cated. Pro
cedures relating solely to matters of internal man-
agement ar
e not published; however, statements of internal
practices
and procedures that affect the rights and duties of
taxpayers
are published.
Revenue rulings represent the conclusions of the Service on the
application of the law to the pivotal facts stated in the revenue
ruling. In those based on positions taken in rulings to taxpayers
or technical advice to Service field offices, identifying details
and information of a confidential nature are deleted to prevent
unwarranted invasions of privacy and to comply with statutory
requirements.
Rulings and procedures reported in the Bulletin do not have the
force and effect of Treasury Department Regulations, but they
may be used as precedents. Unpublished rulings will not be
relied on, used, or cited as precedents by Service personnel in
the disposition of other cases. In applying published rulings and
procedures, the effect of subsequent legislation, regulations,
court decisions, rulings, and procedures must be considered,
and Service personnel and others concerned are cautioned
against reaching the same conclusions in other cases unless
the facts and circumstances are substantially the same.
The Bulletin is divided into four parts as follows:
Part I.—1986 Code.
This part includes rulings and decisions based on provisions of
the Internal Revenue Code of 1986.
Part II.—Treaties and Tax Legislation.
This part is divided into two subparts as follows: Subpart A,
Tax Conventions and Other Related Items, and Subpart B, Leg-
islation and Related Committee Reports.
Part III.—Administrative, Procedural, and Miscellaneous.
To the extent practicable, pertinent cross references to these
subjects are contained in the other Parts and Subparts. Also
included in this part are Bank Secrecy Act Administrative Rul-
ings. Bank Secrecy Act Administrative Rulings are issued by
the Department of the Treasury’s Office of the Assistant Secre-
tary (Enforcement).
Part IV.—Items of General Interest.
This part includes notices of proposed rulemakings, disbar-
ment and suspension lists, and announcements.
The last Bulletin for each month includes a cumulative index
for the matters published during the preceding months. These
monthly indexes are cumulated on a semiannual basis, and are
published in the last Bulletin of each semiannual period.

ents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

(1) ad
d to the value, or substantially pro-
long t
he useful life, of property owned by
the ta
xpayer, or (2) adapt the property to a

lati
ons also provided that amounts paid or

sect

2013–43 I.R.B.331October 21, 2013

Tax Regulations are not capital expendi-
tures under §1.263(a)–1.
The determination of whether an ex-
pense may be deducted as a repair or must
be capitalized generally requires an ex-
amination of all of a taxpayer’s particu-
lar facts and circumstances. Moreover, the
subjective nature of the existing standards
described above has resulted in consider-
able controversy between taxpayers and
the IRS over many years.
In 2006, in an effort to reduce the con-
troversy in this area, the IRS and the Trea-
sury Department published in theFederal
RegisterAugust 21, 2006 (71 FR 48590)
proposed amendments to the regulations
under section 263(a) relating to amounts
paid to acquire, produce, or improve tan-
gible property. The IRS and the Trea-
sury Department received numerous writ-
ten comments in response to these pro-
posed regulations. After considering these
comments and the statements at the pub-
lic hearing, in 2008 the IRS and the Trea-
sury Department withdrew the 2006 pro-
posed regulations and proposed new regu-
lations in theFederal RegisterMarch 10,
2008 (73 FR 12838). The IRS and the
Treasury Department also received many
written comments and held a public hear-
ing on the 2008 proposed regulations. On
December 27, 2011, the IRS and the Trea-
sury Department published temporary reg-
ulations in theFederal Registerregard-
ing the deduction and capitalization of ex-
penditures related to tangible property (TD
9564; 76 FR 81060), withdrew the 2008
proposed regulations, and published new
proposed regulations that cross referenced
the text of the 2011 temporary regulations.
The 2011 temporary regulations initially
applied to taxable years beginning on or af-
ter January 1, 2012. The IRS and the Trea-
sury Department received numerous writ-
ten comments in response to the 2011 tem-
porary and proposed regulations and held
a public hearing on May 9, 2012. After
considering these comments and the state-
ments at the public hearing, the IRS and
the Treasury Department published No-
tice 2012–73 (2012–51 I.R.B. 713), on
November 20, 2012, announcing that, to
assist taxpayers in their transitions to the
2011 temporary regulations and final reg-
ulations, the IRS and the Treasury Depart-
ment would change the applicability date
of the 2011 temporary regulations to tax-
able years beginning on or after January 1,
2014, while permitting taxpayers to choose
to apply the 2011 temporary regulations to
taxable years beginning on or after January
1, 2012, and before the applicability date
of the final regulations. The Notice also
alerted taxpayers that the IRS and the Trea-
sury Department intended to publish final
regulations in 2013 and expected the final
regulations to apply to taxable years begin-
ning on or after January 1, 2014, but that
the final regulations would permit taxpay-
ers to apply its provisions to taxable years
beginning on or after January 1, 2012.
On December 17, 2012, the Treasury De-
partment and the IRS published technical
amendments to TD 9564, which amended
the applicability date of the 2011 tempo-
rary regulations to taxable years beginning
on or after January 1, 2014, while permit-
ting taxpayers to choose to apply the 2011
temporary regulations to taxable years be-
ginning on or after January 1, 2012, and
before the applicability date of the final
regulations. SeeFederal Register(77 FR
74583).
After considering all of the comments
and the statements made at the public hear-
ing on the 2011 temporary and proposed
regulations, the IRS and the Treasury De-
partment are removing the 2011 temporary
regulations under sections 162, 165, 167,
263(a), 263A, 1016, and §1.168(i)–7 and
are issuing final regulations. The IRS and
the Treasury Department are also remov-
ing the 2011 proposed regulations and are
issuing new proposed regulations regard-
ing the disposition of property subject to
section 168. The proposed regulations are
set forth in this issue of the Bulletin.
Explanation of Provisions
I.Overview
Section 263(a) generally requires the
capitalization of amounts paid to acquire,
produce, or improve tangible property.
Section 162 allows a deduction for all
the ordinary and necessary expenses paid
or incurred during the taxable year in
carrying on any trade or business, includ-
ing the costs of certain supplies, repairs,
and maintenance. These final regula-
tions provide a general framework for
distinguishing capital expenditures from
supplies, repairs, maintenance, and other
deductible business expenses. The final
regulations retain many of the provisions
of the 2011 temporary and proposed reg-
ulations (2011 temporary regulations),
which in many instances incorporated
standards from case law and other ex-
isting authorities under sections 162 and
263(a). The final regulations also modify
several sections of the 2011 temporary
regulations in response to comments re-
ceived and to clarify and simplify the rules
while achieving resultsthat are consistent
with the case law. The final regulations
adopt the same general format as the 2011
temporary regulations, where §1.162–3
provides rules for materials and supplies,
§1.162–4 addresses repairs and main-
tenance, §1.263(a)–1 provides general
rules for capital expenditures, §1.263(a)–2
provides rules for amounts paid for the
acquisition or production of tangible prop-
erty, and §1.263(a)–3 provides rules for
amounts paid for the improvement of
tangible property. However, the final reg-
ulations refine and simplify some of the
rules contained in the 2011 temporary reg-
ulations and create a number of new safe
harbors. For example, the final regulations
adopt a revised and simplifiedde min-
imissafe harbor under §1.263(a)–1(f) and
extend the safe harbor for routine mainte-
nance under §1.263(a)–3(i) to buildings.
The final regulations also add a safe harbor
for small taxpayers to the rules governing
improvements to tangible property under
§1.263(a)–3. In addition, the final reg-
ulations refine several of the criteria for
defining betterments and restorations to
tangible property.
In addition, these regulations finalize
certain temporary regulations under sec-
tion 167 regarding accounting for and
retirement of depreciable property and
section 168 regarding accounting for
MACRS property, other than general asset
accounts. However, these regulations do
not finalize the rules under §1.168(i)–1T
or §1.168(i)–8T addressing the definition
of disposition for property subject to sec-
tion 168. Instead, to address significant
changes in this area, revised regulations
under section 168 are being proposed con-
currently with these final regulations (and
appear in this issue of the Bulletin).
II.Materials and Supplies Under
§1.162–3
Responding to generally favorable
comments on the treatment of materi-
October 21, 20133322013–43 I.R.B.

als and supplies in the 2011 temporary
regulations, the final regulations retain
the framework and many of the rules set
forth in the 2011 temporary regulations.
In response to comments, however, the
final regulations expand the definition of
materials and supplies to include property
that has an acquisition or production cost
of $200 or less (increased from $100 or
less), clarify application of the optional
method of accounting for rotable and
temporary spare parts, and simplify the
application of thede minimissafe harbor
of §1.263(a)–1(f) to materials and sup-
plies. The final regulations also define
standby emergency spare parts and limit
the application of the election to capital-
ize materials and supplies to only rotable,
temporary, and standby emergency spare
parts.
A.Definition of materials and supplies
Commenters requested that the dollar
threshold for characterizing a unit of prop-
erty as a material or supply be increased
from property with an acquisition cost of
$100 or less to property with an acquisition
cost of $500 or $1,000. Specifically, com-
menters were concerned that the low $100
threshold would not capture many com-
mon supplies such as calculators and cof-
fee makers. Balancing concerns over dis-
tortions to income that could result from
increasing the acquisition cost to $500 (or
more) with the need to include the typical
materials and supplies ordinarily used by
many taxpayers, the final regulations in-
crease the $100 threshold to $200. In ad-
dition, the final regulations retain the lan-
guage providing the IRS and the Treasury
Department with the authority to change
the amount of this threshold through pub-
lished guidance.
Commenters also continued to question
the effect of the 2011 temporary regula-
tions on the treatment of standby emer-
gency spare parts under Rev. Rul. 81–185
(1981–2 C.B. 59). To resolve questions in
this area, the final regulations generally in-
corporate the definition of standby emer-
gency spare parts provided in Rev. Rul.
81–185 into the definition of materials and
supplies and provide that these parts are el-
igible for the optional election to capitalize
certain materials and supplies provided in
§1.162–3(d).
B.Election to capitalize certain materials
and supplies
The 2011 temporary regulations re-
tained the rule from the 2008 proposed
regulations permitting a taxpayer to elect
to capitalize and depreciate amounts paid
for certain materials and supplies. Sev-
eral comments noted that the requirement
to elect to capitalize certain material and
supply costs continued to be inconsistent
with prior IRS pronouncements that dis-
tinguished certain depreciable property
from materials and supplies. See, for ex-
ample, Rev. Rul. 2003–37 (2003–1 C.B.
717) (permitting taxpayers to treat cer-
tain rotable spare parts used in a service
business as depreciable assets); Rev. Rul.
81–185 (1981–2 C.B. 59) (concluding that
major standby emergency spare parts are
depreciable property); Rev. Rul. 69–201
(1969–1 C.B. 60) (holding that standby
replacement parts used in pit mining busi-
ness are items for which depreciation is
allowable); Rev. Rul. 69–200 (1969–1
C.B. 60) (holding that flight equipment
rotable spare parts and assemblies are
tangible property for which deprecia-
tion is allowable while expendable flight
equipment spare parts are materials and
supplies); Rev. Proc. 2007–48 (2007–2
C.B. 110) (providinga safe harbor method
of accounting to treat certain rotable spare
parts as depreciable assets). In addition,
several comments noted that the rule under
the 2011 temporary regulations could lead
to problematic results, such as permitting
a component acquired to improve a unit of
tangible property owned by the taxpayer
to be treated as an asset and depreciated
over a recovery period different from the
unit of tangible property intended to be
improved.
To address these concerns, the final reg-
ulations retain the rule permitting a tax-
payer to elect to capitalize and depreciate
amounts paid for certain materials and sup-
plies but provide that this rule is only ap-
plicable to rotable, temporary, or standby
emergency spare parts. By limiting the ap-
plication of the rule to rotable, temporary,
or standby emergency spare parts, the final
regulations resolve the potentially prob-
lematic results arising in the 2011 tempo-
rary regulations. And while the final rule
modifies Rev. Rul. 2003–37, Rev. Rul.
81–185, Rev. Rul. 69–200, and Rev. Rul.
69–201 to the extent that the regulations
characterize certain tangible properties ad-
dressed in these rulingsas materials and
supplies, the treatment is consistent with
the holdings of the revenue rulings, which
permit taxpayers to treat rotable, tempo-
rary, or standby emergency spare parts as
assets subject to the allowance for depreci-
ation.
The final regulations also clarify the
procedure for a taxpayer that wants to re-
voke the election tocapitalize and depre-
ciate certain materials and supplies. The
taxpayer may revoke this election by filing
a request for a letter ruling and obtaining
the consent of the Commissioner of Inter-
nal Revenue to revoke this election. The
Commissioner may grant a request to re-
voke this election if the taxpayer acted rea-
sonably and in good faith, and the revo-
cation will not prejudice the interests of
the Government. In deciding whether to
grant such a request, the Commissioner an-
ticipates applying standards similar to the
standards under §301.9100–3 of this chap-
ter for granting extensions of time for mak-
ing regulatory elections.
Finally, one commenter requested that
the rules governing materials and sup-
plies be modified to address the cost of
acquiring or producing rotable spare parts
that a taxpayer leases to customers in the
ordinary course of the taxpayer’s leas-
ing business. This commenter requested
that the final regulations clarify that these
leased rotable spare parts are included in
the definition of rotable and temporary
spare parts and that a taxpayer may elect
to capitalize and depreciate these leased
rotable spare parts under the materials and
supplies rules. Under the 2011 temporary
regulations, the definition of rotable and
temporary spare parts includes only com-
ponents acquired to maintain, repair, or
improve a unit of property owned, leased,
or serviced by the taxpayer. This defini-
tion of rotable and temporary spare parts
does not include components that the tax-
payer leases to its customers and that are
unrelated to other property owned, leased
to other parties, or serviced by the tax-
payer. The final regulations do not expand
the definition of rotable and temporary
spare parts to include leased rotable spare
parts. The IRS and the Treasury Depart-
ment believe that these parts are outside
the scope of regulations governing materi-
als and supplies.
2013–43 I.R.B.333October 21, 2013

C.Optional method for rotable and
temporary spare parts
One commenter requested that the final
regulations remove the requirement that
the optional method for rotable and tem-
porary spare parts, if elected, be used for
all of a taxpayer’s rotable and temporary
spare parts in the same trade or business.
Recognizing that taxpayers may have
pools of rotable or temporary parts that are
treated differently for financial statement
purposes, the final regulations modify this
rule. The final regulations provide that
a taxpayer that uses the optional method
for rotable and temporary spare parts for
Federal tax purposes must use the optional
method for all of the pools of rotable and
temporary spare parts used in the same
trade or business for which the optional
method is used for the taxpayer’s books
and records. Thus, a taxpayer generally is
not required to use the optional method for
those pools of rotable or temporary spare
parts for which it does not use the optional
method in its books and records for the
trade or business. However, if a taxpayer
chooses to use the optional method for any
pool of rotable or temporary spare parts
for which the taxpayer does not use the
optional method in its books and records
for the trade or business, then the taxpayer
must use the optional method for all its
pools of rotable and temporary spare parts
in that trade or business.
Commenters also requested that the
optional method for rotable and temporary
spare parts be treated as the default method
of accounting for rotable and temporary
spare parts, instead of treating rotable and
temporary spare parts as used and con-
sumed in the taxable year when disposed.
Many taxpayers do not use the optional
method of accounting for rotable and
temporary spare parts, and that method
requires a degree of record keeping that
would be overly burdensome for all tax-
payers. Therefore, the final regulations
do not adopt this suggestion and continue
to generally treat rotable and temporary
spare parts as materials and supplies that
are used and consumed in the taxable year
when disposed of by the taxpayer, unless
the taxpayer chooses a different treatment
under §1.162–3.
D.Materials and supplies under the de
minimis safe harbor
There were numerous comments on the
application of thede minimisrule provided
in the 2011 temporary regulations to ma-
terials and supplies under §§1.162–3T(f)
(electiontoapplyde minimisrule to ma-
terials and supplies) and 1.263(a)–2T(g)
(generalde minimisrule) and the interac-
tion between the two sections. In response
to these comments, the final regulations
more clearly coordinate the two provisions
as addressed below in the discussion of the
de minimissafe harbor.
E.Property treated as materials and
supplies in published guidance
Several commenters questioned the
effect of the 2011 temporary regulations
on prior published guidance that permits
taxpayers to treat certain property as ma-
terials and supplies. For example, Rev.
Proc. 2002–12 (2002–1 C.B. 374) allows
a taxpayer to treat smallwares as materials
and supplies that are not incidental under
§1.162–3. Similarly, Rev. Proc. 2002–28
(2002–1 C.B. 815) allows a qualifying
small business taxpayer to treat certain
inventoriable items in the same manner as
materials and supplies that are not inciden-
tal under §1.162–3. The final regulations
do not supersede, obsolete, or replace
these revenue procedures to the extent
they deem certain property to constitute
materials and supplies under §1.162–3.
This designated property continues to
qualify as materials and supplies under the
final regulations, because the definition
of material and supplies includes property
that is identified as materials and supplies
in published guidance.
III.Repairs Under §1.162–4
The 2011 temporary regulations pro-
vided that amounts paid for repairs and
maintenance to tangible property are de-
ductible if the amounts paid are not re-
quired to be capitalized under §1.263(a)–3.
The IRS and the Treasury Department re-
ceived no comments on this regulation.
The final regulations retain the rule from
the 2011 temporary regulations. In addi-
tion, the final regulations add a cross ref-
erence to §1.263(a)–3(n), the new election
to capitalize amounts paid for repair and
maintenance consistent with the taxpayer’s
books and records, discussed later in this
preamble.
IV.De Minimis Safe Harbor Under
§§1.263(a)–1(f) and 1.162–3(f)
A.De minimis safe harbor ceiling
The 2011 temporary regulations re-
quired a taxpayer to capitalize amounts
paid to acquire or produce a unit of
real or personal property, including the
related transaction costs.However,
§1.263(a)–2T(g) provided ade minimis
exception permitting a taxpayer to deduct
certain amounts paid for tangible property
if the taxpayer had an applicable financial
statement, had written accounting proce-
dures for expensing amounts paid for such
property under specified dollar amounts,
and treated such amounts as expenses on
its applicable financial statement. Under
§1.263(a)–2T(g)(1)(iv), a taxpayer’sde
minimisdeduction for the taxable year was
limited to a ceiling: the greater of (1) 0.1
percent of the taxpayer’s gross receipts for
the taxable year as determined for Fed-
eral income tax purposes, or (2) 2 percent
of the taxpayer’s total depreciation and
amortization expense for the taxable year
as determined on the taxpayer’s applicable
financial statement.
The IRS and the Treasury Department
received a significant number of com-
ments addressing thede minimissafe har-
bor provided in §1.263(a)–2T(g). Nearly
all comments raised concerns about the
administrative burden the ceiling would
place on taxpayers, noting that taxpay-
ers would be required to keep detailed
accounts of amounts that they generally
do not track because such amounts are
expensed under their financial accounting
capitalization policies. Thus, while the
ceiling itself could be calculated relatively
simply, the financial accounting systems
employed by most taxpayers would not
allow them to easily determine which
costs thede minimisrule applied to and,
therefore, whether or not applicable costs
exceeded the ceiling. Commenters also
pointed out that the operation of the ceil-
ing requirement did not allow taxpayers
to anticipate when they had reached the
gross receipts or depreciation limitation or
to identify assets that would be excluded
under thede minimisrule during a taxable
year, because the ceiling amount could
October 21, 20133342013–43 I.R.B.

only be calculated after the end of a taxable
year. Commenters also highlighted the
complexities inherent in the application
of the ceiling requirement for consoli-
dated groups. In many cases, commenters
suggested that the administrative burden
imposed would outweigh any potential
tax benefit. Many commenters suggested
that this problem be resolved by remov-
ing the ceiling altogether and permitting
taxpayers to deduct for Federal income
tax purposes amounts properly expensed
under their financial accounting policies.
The final regulations adopt com-
menters’ suggestions that the ceiling in
thede minimisrule in the 2011 tempo-
rary regulations be eliminated and that
amounts properly expensed under a tax-
payer’s financial accounting policies be
deductible for tax purposes. To both
address taxpayers’ concerns and ensure
that thede minimissafe harbor in the
final regulations requires taxpayers to
use a reasonable, consistent methodol-
ogy that clearly reflects income for Fed-
eral income tax purposes, the ceiling in
§1.263(a)–2T(g)(1)(iv) has been replaced
with a new safe harbor determined at the
invoice or item level and based on the
policies that the taxpayer utilizes for its
financial accounting books and records.
A taxpayer with an applicable financial
statement may rely on thede minimissafe
harbor under §1.263(a)–1(f) of the final
regulations only if the amount paid for
property does not exceed $5,000 per in-
voice, or per item as substantiated by the
invoice. The final regulations provide the
IRS and the Treasury Department with the
authority to change the safe harbor amount
through published guidance.
Commenters also asked that thede min-
imissafe harbor be expanded to include
not only amounts paid for property cost-
ing less than a certain dollar amount but
also amounts paid for property having a
useful life less than a certain period of
time. The final regulations adopt this sug-
gestion and provide that thede minimis
safe harbor also applies to a financial ac-
counting procedure that expenses amounts
paid for property with an economic use-
ful life of 12 months or less as long as the
amount per invoice (or item) does not ex-
ceed $5,000. Such amounts are deductible
under thede minimisrule whether this fi-
nancial accounting procedure applies in
isolation or in combination with a finan-
cial accounting procedure for expensing
amounts paid for property that does not ex-
ceed a specified dollar amount. Under ei-
ther procedure, if the cost exceeds $5,000
per invoice (or item), then the amounts
paid for the property will not fall within
thede minimissafe harbor. In addition,
an anti-abuse rule is provided to aggregate
costs that are improperly split among mul-
tiple invoices.
B.Taxpayers without an applicable
financial statement
The 2011 temporary regulations did
not provide ade minimissafe harbor for
taxpayers without an applicable financial
statement, but the preamble requested
comments addressing alternatives that
would provide the IRS and the Treasury
Department with assurance that a taxpayer
is using a reasonable, consistent method-
ology that clearly reflects income. One
commenter suggested that the definition
of applicable financial statement be ex-
panded to include financial statements
subject to a compliance review under the
rules of the American Institute of Certified
Public Accountants’ (AICPA) Statement
of Standards for Accounting and Re-
view Services. Numerous comments also
requested that thede minimisrule be gen-
erally expanded to taxpayers without an
applicable financial statement.
The final regulations include ade min-
imisrule for taxpayers without an applica-
ble financial statement. While careful con-
sideration was given to the suggestion of
relying on reviewed financial statements
as defined in the AICPA’s Statement of
Standards for Accounting and Review Ser-
vices, the final regulations do not adopt
this standard. While the AICPA standard
for reviewed financial statements ensures
that the taxpayer’s policies comply with
the applicable financial accounting frame-
work, the standard does not contemplate a
review of the taxpayer’s internal control,
fraud risk, or accounting records. Thus,
the standard does not provide sufficient
assurance to the IRS that such policies
are being followed and, accordingly, that
the taxpayer is using a reasonable, consis-
tent methodology that clearly reflects its
income. However, the final regulations
do provide ade minimissafe harbor for
taxpayers without an applicable financial
statement if accounting procedures are in
place to deduct amounts paid for property
costing less than a specified dollar amount
or amounts paid for property with an eco-
nomic useful life of 12 months or less.
Thede minimissafe harbor for taxpayers
without an applicable financial statement
provides a reduced per invoice (or item)
threshold because there is less assurance
that the accounting procedures clearly re-
flect income. A taxpayer without an appli-
cablefinancialstatementmayrelyonthe
de minimissafe harbor only if the amount
paid for property does not exceed $500 per
invoice, or per item as substantiated by the
invoice. If the cost exceeds $500 per in-
voice (or item), then no portion of the cost
of the property will fall within thede min-
imissafe harbor. Similar to the safe harbor
for a taxpayer with an applicable financial
statement, this provision provides the IRS
and the Treasury Department with the au-
thority to change the safe harbor amount
through published guidance. In addition,
an anti-abuse rule is provided to aggregate
costs that are improperly split among mul-
tiple invoices.
Finally, for both taxpayers with appli-
cable financial statements and taxpayers
without applicable financial statements,
thede minimissafe harbor is not intended
to prevent a taxpayer from reaching an
agreement with its IRS examining agents
that, as an administrative matter, based on
risk analysis or materiality, the IRS exam-
ining agents will not review certain items.
It is not intended that examining agents
must now revise their materiality thresh-
olds in accordance with thede minimis
safe harbor limitations provided in the fi-
nal regulation. Thus, if examining agents
and a taxpayer agree that certain amounts
in excess of thede minimissafe harbor
limitations are not material or otherwise
should not be subject to review, that agree-
ment should be respected, notwithstanding
the requirements of thede minimissafe
harbor. However, a taxpayer that seeks
a deduction for amounts in excess of the
amount allowed by the safe harbor has
the burden of showing that such treatment
clearly reflects income.
C.Safe harbor election
Commenters asked whether thede min-
imisrule in the 2011 temporary regula-
tions was mandatory or elective and, if
mandatory, requested a change to make
2013–43 I.R.B.335October 21, 2013

the safe harbor elective. The final regula-
tions adopt these suggestions and provide
that thede minimisrule is a safe harbor,
elected annually by including a statement
on the taxpayer’s timely filed original Fed-
eral tax return for the year elected. The
final regulations provide that, if elected,
thede minimissafe harbor must be ap-
plied to all amounts paid in the taxable
year for tangible property that meet the re-
quirements of thede minimissafe harbor,
including amounts paid for materials and
supplies that meet the requirements. In ad-
dition, the final regulations provide that a
taxpayer may not revoke an election to use
thede minimissafe harbor. An election to
use thede minimissafe harbor may not be
made through the filing of an application
for change in accounting method.
D.Written accounting procedures
The 2011 temporary regulations re-
quired that to utilize thede minimissafe
harbor, a taxpayer must have written
accounting procedures in place at the be-
ginning of the taxable year treating the
amounts paid for property costing less
than a certain dollar amount as an expense
for financial accounting purposes. Com-
menters suggested that transition guidance
be issued for taxpayers that did not have
written accounting procedures in place at
the beginning of 2012. Alternatively, one
commenter suggested that taxpayers be
allowed to make the drafting of a written
accounting procedure retroactive to the
beginning of 2012.
The final regulations do not adopt these
suggestions for transition relief. Although
the publication of the 2011 temporary reg-
ulations late in the calendar year (Decem-
ber 27, 2011) likely prevented taxpayers
without written accounting procedures at
that time from implementing such proce-
dures prior to the beginning of the 2012
taxable year, the provisions of the 2011
temporary regulationsare elective for tax-
able years beginning prior to January 1,
2014. In addition, the final regulations are
not applicable until taxable years begin-
ning on or after January 1, 2014. There-
fore, taxpayers without written account-
ing procedures that choose to elect thede
minimissafe harbor for their 2014 tax-
able years should have sufficient time to
consider and draft appropriate procedures
prior to the applicability date of the fi-
nal regulations. Moreover, thede minimis
safe harbor is intendedtoproviderecord-
keeping simplicity to taxpayers by allow-
ing them to follow an established financial
accounting policy for federal tax purposes,
and allowing retroactive application is in-
consistent with such purpose.
E.Application to consolidated group
members
Several comments noted that the rule
for use of a consolidated group’s applica-
ble financial statement failed to consider
situations in which taxpayers are included
on a consolidated applicable financial
statement but are not members in an under-
lying consolidated group for Federal in-
come tax purposes. Comments requested
that taxpayers in this situation be permit-
ted to rely on the financial policies of the
group that apply to them as well as the
group’s consolidated applicable financial
statement to satisfy the requirements of
thede minimisrule. The final regulations
adopt this suggestion and provide that if
a taxpayer’s financial results are reported
on the applicable financial statement for a
group of entities, then the group’s appli-
cable financial statement may be treated
as the applicable financial statement of
the taxpayer. Furthermore, in this situ-
ation, the written accounting procedures
provided for the group and utilized for
the group’s applicablefinancial statement
may be treated as the written accounting
procedures of the taxpayer.
F.Transaction and other additional costs
The preamble to the 2011 temporary
regulations provided that thede minimis
rule did not apply to amounts paid for
labor and overhead incurred in repair-
ing or improving property. Commenters
pointed out that the preamble did not pro-
vide any policy reason for excluding labor
and overhead costs from thede minimis
rule and that the exclusion would require
rules to allocate additional invoice costs,
such as freight and installation costs, be-
tween tangible property costs and labor
and overhead costs, requiring additional
recordkeeping by taxpayers. Addition-
ally, one commenter pointed out that the
de minimisrule in the 2011 temporary
regulations did not expressly provide for
an exclusion of labor and overhead costs.
Commenters requested that additional
costs included on an invoice for tangible
property be includedwithin the scope of
thede minimisrule.
The final regulations adopt the com-
menters’ suggestions, in part, and clarify
the treatment under thede minimissafe
harbor of transaction costs and other ad-
ditional costs of acquiring and producing
property subject to the safe harbor. To
simplify the application of thede minimis
rule to tangible property, the final regula-
tions provide that a taxpayer electing to ap-
ply thede minimissafe harbor is not re-
quired to include in the cost of the tan-
gible property the additional costs of ac-
quiring or producingsuch property if these
costs are not included in the same invoice
as the tangible property. However, the fi-
nal regulations also provide that a taxpayer
electing to apply thede minimissafe har-
bor must include in the cost of such prop-
erty all additional costs (for example, de-
livery fees, installation services, or simi-
lar costs) of acquiring or producing such
property if these costs are included on the
same invoice with the tangible property. If
an invoice includesamounts paid for mul-
tiple tangible properties and the invoice
includes additional invoice costs related
to the multiple properties, then the tax-
payer must allocate the additional invoice
costs to each property using a reasonable
method. The final regulations specify that
a reasonable allocation method includes,
but is not limited to, specific identification,
apro rataallocation, or a weighted aver-
age method based on each property’s rela-
tive cost. The final regulations also clarify
that additional costs consist of the trans-
action costs (that is, the facilitative costs
under §1.263(a)–2(f)) of acquiring or pro-
ducing the property and the costs under
§1.263(a)–2(d) for work performed prior
to the date that the unit of tangible prop-
erty is placed in service.
G.Materials and supplies
The IRS and Treasury Department re-
ceived numerous comments on the appli-
cation of thede minimisrule to materials
and supplies under §1.162–3T of the 2011
temporary regulations. Under the 2011
temporary regulations, taxpayers were per-
mitted to select materials and supplies to
be expensed under thede minimisrule pro-
vided that these materials and supplies sat-
isfied all requirements of thede minimis
October 21, 20133362013–43 I.R.B.

rule, including the ceiling. Many com-
ments raised concernsabout the adminis-
trative burdens associated with identifying
and allocating materials and supplies be-
tween thede minimisrule and the general
rules for materials and supplies in a man-
ner that would not exceed thede minimis
rule ceiling. In many cases, commenters
suggested that the administrative burden
imposed would outweigh any potential tax
benefit. Thus, commenters requested revi-
sions to thede minimisrule to reduce tax-
payers’ administrative burden of comply-
ing with the 2011 temporary regulations.
To simplify application of thede min-
imissafe harbor, the final regulations re-
quire that thede minimissafe harbor be ap-
plied to all eligible materials and supplies
(other than rotable, temporary, and standby
emergency spare parts subject to the elec-
tion to capitalize or rotable and temporary
spare parts subject to the optional method
of accounting for such parts) if the tax-
payer elects thede minimissafe harbor un-
der §1.263(a)–1(f). Unlike the 2011 tem-
porary regulations rule permitting taxpay-
ers to select materials and supplies for ap-
plication of thede minimissafe harbor, the
requirement in the final regulations to ap-
ply thede minimissafe harbor, if elected,
to all eligible materials and supplies sim-
plifies the application of thede minimis
rule and reduces the administrative burden
on the IRS. Taxpayers that do not elect the
de minimissafe harbor provided in the fi-
nal regulations for the taxable year must
treat their amounts paid for materials and
supplies in accordance with the rules pro-
vided in §1.162–3.
H.Coordination with section 263A
Commenters asked for clarification on
the interaction of thede minimisrule with
section 263A. Several comments asked
whether the application of thede minimis
rule resulted in property with an unad-
justed basis of zero, which would then be
subject to section 263A, or, alternatively,
whether section 263A required taxpayers
to capitalize the cost of property subject
to section 263A, regardless of whether the
de minimisrule applied.
The final regulationsclarify the interac-
tion between the two provisions. The final
regulations provide that amounts paid for
tangible property eligible for thede min-
imissafe harbor may, nonetheless, be sub-
ject to capitalization under section 263A
if the amounts paid for this tangible prop-
erty comprise the direct or allocable indi-
rect costs of other property produced by
the taxpayer or property acquired for re-
sale.
In general, under section 263A, if prop-
erty is held for future production, taxpay-
ers must capitalize direct and indirect costs
allocable to such property (for example,
purchasing, storage, and handling costs),
even though production has not begun. If
property is not held for production, indi-
rect costs incurred prior to the beginning
of the production period must be allocated
to the property and capitalized if, at the
time the costs are incurred, it is reasonably
likely that production will occur at some
future date. Thus, for example, a manu-
facturer must capitalize the costs of stor-
ing and handling raw materials before the
raw materials are committed to production.
In addition, §1.263A–1T(e)(2)(i) provides
that indirect material costs include the cost
of materials that are not an integral part of
specific property produced and the cost of
materials that are consumed in the ordinary
course of performing production or resale
activities that cannot be identified or asso-
ciated with particular units of property.
Therefore, if tangible property is ac-
quired with the expectation of being used
in the production of other property, and it is
reasonably likely that production will oc-
cur at some future date, section 263A may
apply to capitalize the cost of the prop-
erty acquired. Thus, for example, if a tax-
payer acquires a component part, the cost
of which is otherwise eligible for thede
minimissafe harbor, but the component
part is installed, or expected to be installed
in the future, in the taxpayer’s manufac-
turing equipment used to produce property
for sale, under section 263A, the cost of
the component part must be capitalized as
an indirect cost of property produced by
the taxpayer. On the other hand, if prop-
erty is acquired without the expectation of
being used in the production of property
and the taxpayer elects and properly ap-
plies thede minimisrule to the amount paid
for property in the taxable year, if expecta-
tions change in a subsequent taxable year
and the property is actually used in pro-
duction, then section 263A will not require
capitalization of the cost of the property at
the time the expectation changes or when
the property is used in production.
I.Change in accounting procedures not
change in method of accounting
Several commenters questioned
whether a change in a taxpayer’s financial
accounting procedures (for example, its
financial accounting capitalization policy)
is a change in method of accounting for
de minimisexpenses to which the pro-
visions of sections 446 and 481 and the
accompanying regulations apply. The fi-
nal regulations provide that the use of the
de minimissafe harbor is a taxable year
election and may not be made by the filing
of an application for a change in method of
accounting. Thus, if a taxpayer meets the
requirements for the safe harbor, which
requires, in part, having written account-
ing procedures in place at the beginning of
the taxable year and treating amounts paid
for property as an expense in accordance
with those procedures, then a change in
the procedures, by itself, is not a change
in accounting method.For example, if
a taxpayer’s written financial accounting
capitalization policy at the beginning of
2014 states that amounts paid for property
costing less than $200 will be treated as
an expense, and the taxpayer changes its
written policy as of the beginning of 2015
to treat amounts paid for property costing
less that $500 as an expense, the taxpayer
is not required to file an application for
its 2015 taxable year to change its method
of accounting for applying thede minimis
safe harbor or determining amounts paid
to acquire or produce tangible property
under §1.263(a)–1(f).
V.Amounts Paid to Acquire or Produce
Tangible Property Under §1.263(a)–2
Section 1.263(a)–2T of the 2011 tem-
porary regulations provided rules for ap-
plying section 263(a) to amounts paid to
acquire or produce a unit of real or per-
sonal property. In general, the final regu-
lations retain the rules from the 2011 tem-
porary regulations, including general re-
quirements to capitalize amounts paid to
acquire or produce a unit of real or per-
sonal property, requirements to capitalize
amounts paid to defend or perfect title to
real or personal property, and rules for de-
termining the extent to which taxpayers
must capitalize transaction costs related to
the acquisition of property. In the final reg-
ulations, thede minimissafe harbor has
2013–43 I.R.B.337October 21, 2013

been moved to §1.263(a)–1(f) to reflect
its broader application to amounts paid for
tangible property, including amounts paid
for improvements and materials and sup-
plies, except as otherwise provided under
section 263A.
The 2011 temporary regulations pro-
vided that a taxpayer must, in general, cap-
italize amounts paid to facilitate the ac-
quisition or production of real or personal
property. To alleviate controversy between
taxpayers and the IRS, the 2011 tempo-
rary regulations included a list of inher-
ently facilitative amounts. In addition, the
2011 temporary regulations provided that
costs relating to activities performed in the
process of determining whether to acquire
real property and which real property to
acquire generally are deductible pre-deci-
sional costs unless they are described in the
regulations as inherently facilitative costs.
The 2011 temporary regulations also pro-
vided that inherently facilitative amounts
allocable to real or personal property are
capital expenditures related to such prop-
erty, even if such property is not eventually
acquired or produced.
Commenters requestedthat the require-
ment to capitalize facilitative costs be re-
moved as overbroad. Commenters also
stated that it was inappropriate to provide
a special rule that depends on the nature
of the property acquired (real property or
personal property) and inappropriate to re-
quire capitalization of inherently facilita-
tive amounts allocable to property not ac-
quired. Other commenters recommended
that the list describing inherently facili-
tative amounts be revised to exclude ac-
tivities that are dependent on the type of
service provider (forexample, a broker),
rather than being based on a specific ac-
tivity (for example,securing an appraisal).
One commenter asked for clarification re-
garding the treatment of a broker’s com-
mission if the commission was contingent
on the buyer’s successful acquisition of
real property but a portion of the broker’s
activities were performed in investigating
the acquisition.
The final regulations generally retain
the 2011 temporary regulation rules ad-
dressing facilitative amounts. As in the
2011 temporary regulations, the final reg-
ulations include the special rule for the
acquisition of real property providing that,
except for amounts specifically identified
as inherently facilitative, an amount paid
by a taxpayer in the process of investigat-
ing or otherwise pursuing the acquisition
of real property does not facilitate the ac-
quisition if it relates to activities performed
in the process of determining whether to
acquire real property and which real prop-
erty to acquire. The final regulations do
not expand the deduction of such pre-de-
cisional, investigatory costs to personal
property because, unlike real property ac-
quisitions, personal property acquisitions
do not typically raise issues of whether
the transaction costs should be charac-
terized as deductible business expansion
costs rather than costs to acquire a specific
property. In addition, personal property
acquisitions do not typically provide clear
evidence establishingthe timing of deci-
sions. Thus, such a rule could generate
significant controversy over unduly small
amounts.
Moreover, the final regulations retain
the list of inherently facilitative costs that
generally must be capitalized as trans-
action costs. However, in response to
comments, the final regulations clarify
the meaning of finders’ fees and brokers’
commissions and provide a definition of
contingency fees. The final regulations
provide that for purposes of §1.263(a)–2,
a contingency fee is an amount paid that is
contingent on the successful closing of the
acquisition of real or personal property.
The final regulations also clarify that con-
tingency fees facilitate the acquisition of
the property ultimately acquired and are
not allocable to real or personal property
not acquired. Therefore, if a real estate
broker’s commission is contingent on the
successful closing of the acquisition of
real property, the amount paid as the bro-
ker’s commission inherently facilitates
the acquisition of the property acquired
and, therefore, must be capitalized as part
of the basis of such property. However,
no portion of the broker’s contingency
fee is allocable to real property that the
taxpayer did not acquire. In addition, the
final regulations retain the rule that inher-
ently facilitative amounts allocable to real
or personal property are capital expendi-
tures related to such property, even if such
property is not eventually acquired or pro-
duced. As discussed in the preamble to the
2008 proposed regulations, the IRS and
the Treasury Department believe that this
rule is consistent with established author-
ities. See, for example,Sibley, Lindsay
& Curr Co. v. Commissioner,15 T.C.
106 (1950),acq., 1951–1 C.B. 3. The
final regulations also clarify that, except
for contingency fees as discussed above,
inherently facilitative amounts allocable
to property not acquired may be allocated
to those properties and recovered in ac-
cordance with the applicable provisions of
the Code, includingsections 165, 167, and
168.
VI.Amounts Paid to Improve Property
Under §1.263(a)–3
A.Overview
Comments received with respect to the
rules under the 2011 temporary regulations
for determining whether an amount im-
proves, betters, or restores property largely
focused on the application of the rules to
building property, the lack of a safe har-
bor for routine maintenance for building
property, the standards to be applied in
determining whether a betterment has oc-
curred, the treatment of post-casualty ex-
penditures under the restoration standards,
and the standards to be applied in deter-
mining whether a replacement of a ma-
jor component or substantial structural part
has occurred.
The final regulations generally retain
the rules of the 2011 temporary regulations
for determining the unit of property and
for determining whether there is an im-
provement to a unit of property. The fi-
nal regulations also retain the simplifying
conventions set out in the 2011 temporary
regulations, including the routine mainte-
nance safe harbor and the optional regu-
latory accounting method. In addition, in
response to the comments, the final regu-
lations modify the 2011 temporary regula-
tions in several areas. The concerns raised
by commenters and the relevant changes
to the 2011 temporary regulations are dis-
cussed in this preamble.
B.Determining the unit of property
The 2011 temporary regulations gen-
erally defined the unit of property as
consisting of all the components of prop-
erty that are functionally interdependent,
but provided special rules for determin-
ing the unit of property for buildings,
plant property, and network assets. The
2011 temporary regulations also provided
special rules for determining the units of
October 21, 20133382013–43 I.R.B.

property for condominiums, cooperatives,
and leased property, and for the treatment
of improvements (including leasehold im-
provements). The final regulations retain
the unit of property rules contained in the
2011 temporary regulations.
The 2011 temporary regulations gen-
erally defined a building as a unit of
property, but required the application of
the improvement standards to the build-
ing structure and the enumerated building
systems. A number of comments ob-
jected to the requirement that the taxpayer
perform the improvement analysis at the
building structure and system level. The
comments stated that such treatment is
inconsistent with the treatment of other
complex property under the 2011 tem-
porary regulations, is inconsistent with
the treatment of building property under
depreciation rules, and fails to take into
account the relative importance of the var-
ious building systems. Several comments
requested that the building, including its
structural components, should be treated
as the unit of property for applying the
improvement rules to buildings. Other
commenters pointed out that a functional
interdependence standard, used in the
2011 temporary regulations for non-build-
ingpropertyandappliedbythecourtsand
the IRS for determining when components
of a single property are placed in service
for cost recovery purposes, may be a more
consistent general standard for identifying
the relevant property upon which to apply
the improvement analysis.
Like plant property, buildings are com-
plex properties composed of numerous
component parts that perform discrete and
major functions or operations. Unlike
plant property, however, where the dis-
crete and major functions or operations
are not consistent from plant to plant, the
discrete and major functions or operations
performed from building to building are
frequently similar. The building system
definitions set forth in the 2011 temporary
regulations are based on well understood
costing standards that have been routinely
applied to buildings for many years for
valuations, cost accounting, and financial
reporting. To help ensure that the im-
provement standards are applied equitably
and consistently across building property,
the final regulations continue to apply the
improvement rules to both the building
structure and the defined building systems.
To the extent the particular facts and cir-
cumstances of a subset of buildings used
in one or more industries present unique
challenges to application of the building
structure or building system definitions,
taxpayers are encouraged to request guid-
ance under the Industry Issue Resolution
(IIR) procedures.
C.Unit of property for leasehold
improvements
The 2011 temporary regulations pro-
vide rules for determining the unit of
property for leased property and for deter-
mining the unit of property for leasehold
improvements. The IRS and the Treasury
Department received no written comments
on these rules, and the final regulations
retain the rules from the 2011 tempo-
rary regulations, withsome clarifications.
Under the rule in the 2011 temporary reg-
ulations, a question could arise regarding
the property to be analyzed for determin-
ing whether an improvement to a lessee
improvement constitutes an improvement
to the lessee’s property. In this context,
the 2011 temporary regulations suggested
that the taxpayer must determine whether
there has been an improvement to the
lessee improvement by itself, rather than
by applying the improvement standards
to the general unit of property rules for
leased buildings or for leased property
other than buildings. The final regulations
clarify that for purposes of determining
whether an amount paid by a lessee con-
stitutes a leasehold improvement, the unit
of property and the improvement rules
are applied in accordance with the rules
for leased buildings (or leased portions of
building) under §1.263(a)–3(e)(2)(v) or
for leased property other than buildings
under §1.263(a)–3(e)(3)(iv). Thus, for ex-
ample, if a lessee pays an amount for work
on an addition that it previously made to
a leased building, the taxpayer determines
whether the work performed constitutes an
improvement to the entire leased building
structure, not merely to the addition. The
final regulations also clarify that when a
lessee or lessor improvement is comprised
of a building erectedon leased property,
then the unit of property for the building
and the application of the improvement
rules are determined under the provisions
for buildings, rather than under the provi-
sions for leased buildings.
D.Special rules for determining
improvement costs
1. Costs incurred during an improvement
The 2011 temporary regulations did not
prescribe rules related to the “plan of re-
habilitation” doctrine as traditionally de-
scribed in the case law. The judicially-cre-
ated plan of rehabilitation doctrine pro-
vides that a taxpayer must capitalize oth-
erwise deductible repair or maintenance
costs if they are incurred as part of a gen-
eral plan of rehabilitation, modernization,
and improvement to the property. See,
for example,Moss v. Commissioner,831
F.2d 833 (9th Cir. 1987);United States
v. Wehrli, 400 F.2d 686 (10th Cir. 1968);
Norwest Corp. v. Commissioner, 108 T.C.
265 (1997). The 2011 temporary regula-
tions did not restate the plan of rehabil-
itation doctrine but, rather, used the lan-
guage of the section 263A rule providing
that a taxpayer must capitalize both the di-
rect costs of an improvement as well as the
indirect costs that directly benefit or are in-
curred by reason of the improvement. The
2011 temporary regulations also included
an exception to this provision for an indi-
vidual residence, which permitted an in-
dividual taxpayer to capitalize repair and
maintenance costs incurred at the time of a
substantial residential remodel.
The final regulations retain the rules
from the 2011 temporary regulations and
continue to provide that indirect costs,
such as repair and maintenance costs, that
do not directly benefit and that are not
incurred by reason of an improvement
are not required to be capitalized under
section 263(a), regardless of whether they
are incurred at the same time as an im-
provement. In addition, in response to
comments requesting examples of the ap-
plication of this standard, the final regula-
tions add this analysis to several examples.
By providing a standard based on the sec-
tion 263A language, the final regulations
set out a clear rule for determining when
otherwise deductible indirect costs must
be capitalized as part of an improvement
to property and obsolete the plan of re-
habilitation doctrine to the extent that the
court-created doctrineprovides different
standards.
2013–43 I.R.B.339October 21, 2013

2. Removal Costs
The 2011 temporary regulations did not
provide a separate ruleforthetreatmentof
removal costs. Rather, the 2011 temporary
regulations addressed component removal
costs as an example of a type of indirect
cost that must be capitalized if the removal
costs directly benefit or are incurred by
reason of an improvement. The preamble
to the 2011 temporary regulations stated
that the costs of removing a component
of a unit of property should be analyzed
in the same manner as any other indirect
cost (such as a repair cost) incurred dur-
ing a repair or an improvement to prop-
erty. Therefore, the preamble concluded, if
the cost of removing a component of a unit
of property directly benefitted or was in-
curred by reason of an improvement to the
unit of property, the cost must be capital-
ized. The preamble to the 2011 temporary
regulations also noted that the 2011 tempo-
rary regulations werenot intended to affect
the holding of Rev. Rul. 2000–7 (2000–1
C.B. 712) as it applied to the cost of remov-
ing an entire unit of property. Under Rev.
Rul. 2000–7, a taxpayer is not required
to capitalize the cost of removing a retired
depreciable asset under section 263(a) or
section 263A, even when the retirement
and removal occur in connection with the
installation of a replacement asset. Rev.
Rul. 2000–7 reasoned that the costs of re-
moving a depreciable asset generally have
been allocable to the removed asset and,
thus, generally have been deductible when
the asset is retired. See §§1.165–3(b);
1.167(a)–1(c); 1.167(a)–11(d)(3)(x); Rev.
Rul. 74–455 (1974–2 C.B. 63); Rev. Rul.
75–150 (1975–1 C.B. 73).
Commenters acknowledged the pream-
ble language but observed that the 2011
temporary regulations did not explicitly
state that the costs incurred to remove an
entire unit of property are not required to
be capitalized, even when incurred in con-
nection with the installation of a replace-
ment asset. Commenters requested that the
final regulations include this explicit con-
clusion. Commenters also asked whether
the principles of Rev. Rul. 2000–7 would
apply to allow the deduction of removal
costs when the taxpayer disposes of a com-
ponent of a unit of property and the tax-
payer takes into account the adjusted basis
of the component in realizing loss. Com-
menters also questioned whether a tax-
payer would be required to capitalize com-
ponent removal costs if these costs were an
indirect cost of a restoration (for example,
the replacement of a component when the
taxpayer has properly deducted a loss for
that component) rather than a betterment
to the underlying unit of property.
The final regulations provide a spe-
cific rule clarifying the treatment of re-
moval costs in these contexts. The final
regulations state that if a taxpayer dis-
poses of a depreciable asset (including
a partial disposition under Prop. Reg.
§1.168(i)–1(e)(2)(ix) (September 19,
2013), or Prop. Reg. §1.168(i)–8(d)
September 19, 2013)) for Federal tax
purposes and has taken into account the
adjusted basis of the asset or component
of the asset in realizing gain or loss, the
costs of removing the asset or component
are not required to be capitalized under
section 263(a). The final regulations also
provide that if a taxpayer disposes of a
component of a unit of property and the
disposal is not a disposition for Federal tax
purposes, then the taxpayer must deduct
or capitalize the costs of removing the
component based on whether the removal
costs directly benefit or are incurred by
reason of a repair to the unit of property or
an improvement to the unit of property. In
addition, the final regulations provide sev-
eral examples illustrating these principles.
E.Safe harbor for small taxpayers
The 2011 temporary regulations did not
provide any special rules for small tax-
payers to assist them in applying the gen-
eral rules for improvements to buildings.
One commenter stated that small taxpayers
generally do not have the administrative
means or sufficientdocumentation or in-
formation to apply the improvement rules
to their building structures and systems as
required under the 2011 temporary reg-
ulations. Therefore, the commenter re-
quested that an annual dollar threshold,
such as $10,000, be established for build-
ings with an initial cost of $1,000,000 or
less and that taxpayers be permitted to
deduct annual amounts spent on the build-
ing if they did not exceed the threshold
amount. In response to this request, the fi-
nal regulations include a safe harbor elec-
tionforbuildingpropertyheldbytaxpay-
ers with gross receipts of $10,000,000 or
less (“a qualifying small taxpayer”). The
final regulations permit a qualifying small
taxpayer to elect to not apply the improve-
ment rules to an eligible building property
if the total amount paid during the taxable
year for repairs, maintenance, improve-
ments, and similar activities performed on
the eligible building does not exceed the
lesser of $10,000 or 2 percent of the un-
adjusted basis of the building. Eligible
building property includes a building unit
of property that is owned or leased by
the qualifying taxpayer, provided the un-
adjusted basis of the building unit of prop-
erty is $1,000,000 or less. The final reg-
ulations provide the IRS and the Treasury
Department with the authority to adjust the
amounts of the safe harbor and gross re-
ceipts limitations through published guid-
ance. The final regulations provide sim-
ple rules for determining the unadjusted
basis of both owned and leased building
units of property. In this situation, the fi-
nal regulations alsoeliminate the need to
separately analyze the building structure
and the building systems, as required else-
where in the improvement rules in the final
regulations.
Under the safe harbor for small tax-
payers, a taxpayer includes amounts not
capitalized under thede minimissafe har-
bor election of §1.263(a)–1(f) and under
the routine maintenance safe harbor for
buildings (discussed later in this pream-
ble) to determine the annual amount paid
for repairs, maintenance, improvements,
and similar activities performed on the
building. If the amount paid for repairs,
maintenance, improvements, and similar
activities performed on a building unit of
property exceeds the safe harbor threshold
for a taxable year, then the safe harbor
is not applicable to any amounts spent
during the taxable year. In that case, the
taxpayer must apply the general rules
for determining improvements, including
the routine maintenance safe harbor for
buildings. The taxpayer may also elect
to apply thede minimissafe harbor under
§1.263(a)–1(f) to amounts qualifying un-
der thede minimissafe harbor, regardless
of the application of the safe harbor for
small taxpayers.
The safe harbor for building property
held small taxpayers may be elected an-
nually on a building-by-building basis by
including a statement on the taxpayer’s
timely filed original Federal tax return, in-
cluding extensions, for the year the costs
October 21, 20133402013–43 I.R.B.

are incurred for the building. Amounts
paid by the taxpayer to which the tax-
payer properly applies and elects the safe
harbor are not treated as improvements to
the building under §1.263(a)–3 and may
be deducted under §1.162–1 or §1.212–1,
as applicable, in the taxable year that the
amounts are paid or incurred, provided the
amounts otherwise qualify for deduction
under those sections. A taxpayer may not
revoke an election to apply the safe harbor
for small taxpayers.
F.Safe harbor for routine maintenance
1. Buildings
The 2011 temporary regulations pro-
vided that the costs of performing certain
routine maintenance activities for property
other than a building or the structural com-
ponents of a building are not required to
be capitalized as an improvement. Under
the routine maintenance safe harbor, an
amount paid was deemed not to improve
a unit of property if it was for the recur-
ring activities that a taxpayer (or a lessor)
expected to perform as a result of the tax-
payer’s (or the lessee’s) use of the unit of
property to keep the unit of property in its
ordinarily efficient operating condition.
The 2011 temporary regulations provided
that the activities are routine only if, at
the time the unit of property was placed
in service, the taxpayer reasonably ex-
pected to perform the activities more than
once during the period prescribed under
sections 168(g)(2) and168(g)(3) (the Al-
ternative Depreciation System class life),
regardless of whether the property was
depreciated under the Alternative Depre-
ciation System. The preamble to the 2011
temporary regulations explained that the
routine maintenance safe harbor did not
apply to building property, because the
long class life for such property (40 years
under section 168(g)(2)) arguably could
allow major remodeling or restoration
projects to be deducted under the safe
harbor, regardless of the nature or extent
of the work involved, and that deducting
such costs would be inconsistent with
case law. The 2011 temporary regulations
provided several factors for taxpayers to
consider in determining whether a tax-
payer is performing routine maintenance,
including the recurring nature of the ac-
tivity, industry practice, manufacturers’
recommendations, the taxpayer’s experi-
ence, and the taxpayer’s treatment of the
activity on its applicable financial state-
ment.
Comments on the routine maintenance
safe harbor generally requested that the
safe harbor be extended to building prop-
erty. One commenter stated that because
the improvement standards under the 2011
temporary regulations must now be ap-
plied to the building structure and each
building system separately, these compo-
nents are more analogous to section 1245
property, which qualifies for the routine
maintenance safe harbor. Commenters
suggested that using a period shorter than
a building’s class life, such as 20 years,
could alleviate the IRS and the Treasury
Department’s concern that the cost of true
improvements would not be properly cap-
italized if the safe harbor were extended to
buildings. Another commenter argued that
the distinction between building property
and non-building property for purposes
of the safe harbor is arbitrary because, in
many respects, retail buildings are similar
to other complex property, such as aircraft,
which are not excluded from the safe har-
bor.
In response to these comments, the final
regulations contain a safe harbor for rou-
tine maintenance for buildings. The inclu-
sion of a routine maintenance safe harbor
for buildings is expected to alleviate some
of the difficulties that could arise in ap-
plying the improvement standards for cer-
tain restorations to building structures and
building systems. To balance commenters’
suggestions of using a shorter period, such
as 20 years, with the concerns expressed in
the preamble to the 2011 temporary regula-
tions, the final regulations use 10 years as
theperiodoftimeinwhichataxpayermust
reasonably expect to perform the relevant
activities more than once. While periods
longer than 10 years were considered, the
use of a period much longer than 10 years
would, contrary to current authority, per-
mit the costs of many major remodeling
and restoration projects to be deducted un-
der the safe harbor, regardless of the nature
or extent of the work involved.
2. Other Changes
The final regulations make several ad-
ditional changes and clarifications to the
safe harbor for routine maintenance, which
are applicable to both buildings and other
property. First, the regulations confirm
that routine maintenance can be performed
any time during the life of the property
provided that the activities qualify as rou-
tine under the regulation. Second, for pur-
poses of determining whether a taxpayer is
performing routine maintenance, the final
regulations remove the taxpayer’s treat-
ment of the activity on its applicable fi-
nancial statement from the factors to be
considered. Taxpayers may have several
different reasons for capitalizing mainte-
nance activities on their applicable finan-
cial statements, and such treatment may
not be indicative of whether the activi-
ties are routine. Third, the final regula-
tions clarify the applicability of the routine
maintenance safe harbor by adding three
items to the list of exceptions from the rou-
tine maintenance safe harbor: (1) amounts
paid for a betterment to a unit of property,
(2) amounts paid to adapt a unit of property
to a new or different use, and (3) amounts
paid for repairs, maintenance, or improve-
ment of network assets. The first two ex-
ceptions were included in the general rule
for the safe harbor in the 2011 temporary
regulations, but were not clearly stated as
exceptions. The exception for network as-
sets was added because of the difficulty in
defining the unit of property for network
assets and the preference for resolving is-
sues involving network assets through the
IIR program. Finally, the exception relat-
ingtoamountspaidforpropertyforwhich
a taxpayer has taken a basis adjustment
resulting from a casualty loss is slightly
modified to be consistent with the revised
casualty loss restoration rule, which is dis-
cussed in this preamble.
3. Reasonable Expectation that Activities
Will be Performed More than Once
A taxpayer’s reasonable expectation of
whether it will perform qualifying mainte-
nance activities more than once during the
relevant period will be determined at the
time the unit of property (or building struc-
ture or system, as applicable) is placed
in service. The final regulations modify
the safe harbor for routine maintenance by
adding that a taxpayer’s expectation will
not be deemed unreasonable merely be-
cause the taxpayer does not actually per-
form the maintenance a second time dur-
ing the relevant period, provided that the
2013–43 I.R.B.341October 21, 2013

taxpayer can otherwise substantiate that its
expectation was reasonable at the time the
property was placedin service. Thus, for
a unit of property previously placed in ser-
vice, whether the maintenance is actually
performed more than once during the rele-
vant period is not controlling for assessing
the reasonableness of a taxpayer’s original
expectation. However, if a similar or iden-
tical unit of property is placed in service
in a future tax year, the taxpayer’s expe-
rience with the original property may be
taken into account as a factor in assess-
ing whether the taxpayer reasonably ex-
pects to perform the activities more than
once during the relevant period for the sim-
ilar or identical unit of property. The tax-
payer’s actual experience, therefore, may
be used in assessing the reasonableness of
the taxpayer’s expectation of the frequency
of restoration or replacement at the time a
new unit of property is placed in service,
but hindsight should not be used to inval-
idate a taxpayer’s reasonable expectation
as established at the time the unit of prop-
erty was first placed in service when sub-
sequent events do not conform to the tax-
payer’s reasonable expectation.
4. Amounts Not Qualifying for the
Routine Maintenance Safe Harbor
The final regulations clarify that
amounts incurred for activities falling out-
side the routine maintenance safe harbor
are not necessarily expenditures required
to be capitalized under §1.263(a)–3.
Amounts incurred for activities that do not
meet the routine maintenance safe harbor
are subject to analysis under the general
rules for improvements.
G.Betterments
1. Overview
The 2011 temporary regulations pro-
vided that an amount paid results in a
betterment, and accordingly, an improve-
ment, if it (1) ameliorates a material con-
dition or defect that existed prior to the
acquisition of the property or arose during
the production of the property; (2) results
in a material addition to the unit of prop-
erty (including a physical enlargement,
expansion, or extension); or (3) results in
a material increase in the capacity, pro-
ductivity, efficiency, strength, or quality
of the unit of property or its output. As
applied to buildings, an amount results in
a betterment to the building if it results in
a betterment to the building structure or
any of the building systems.
The final regulations retain the provi-
sions of the 2011 temporary regulations
related to betterments with several refine-
ments. Specifically, the final regulations
reorganize and clarify the types of activi-
ties that constitute betterments to property.
Also, the final regulations no longer phrase
the betterment test in terms of amounts
thatresult ina betterment. Rather, the
final regulations provide that a taxpayer
must capitalize amounts that are reason-
ably expected to materially increase the
productivity, efficiency, strength, quality,
or output of a unit of property or that are
for a material addition to a unit of prop-
erty. Elimination of the “results in” stan-
dard should reduce controversy for expen-
ditures that span more than one tax year or
when the outcome of the expenditure is un-
certain when the expenditure is made.
2. Amelioration of Material Condition or
Defect
Commenters requested that certain ex-
amples be clarified to distinguish more
clearly between circumstances that require
capitalization of amounts paid to ame-
liorate a material condition or defect and
circumstances that do not require capital-
ization. One commenter requested that the
final regulations include a rule that would
provide for an allocation of expenditures
between pre- and post-acquisition periods
based on facts and circumstances if an
expenditure both ameliorates a pre-ex-
isting condition and ameliorates normal
wear and tear that results from the tax-
payer’s use of the property. With respect
to whether amounts paid to ameliorate
conditions are betterments, other com-
ments reiterated suggestions provided in
response to the 2008 proposed regulations,
as described in the preamble to the 2011
temporary regulations.
The final regulations do not adopt the
comments with respect to expenditures to
ameliorate pre-existing conditions or de-
fects. The facts and circumstances rule
provided in the final regulations is consis-
tent with established case law and repre-
sents an administrable standard for deter-
mining whether an improvement has oc-
curred.
3. Material Addition or Increase in
Productivity, Efficiency, Strength,
Quality, or Output
Many commenters requested that the fi-
nal regulations provide explanations and
quantitative brightlines for determining
the materiality of an addition to a unit of
property or an increase in capacity, pro-
ductivity, efficiency, strength, quality, or
output of a unit of property. Addition-
ally, commenters requested more explana-
tion of terms such as productivity, qual-
ity, and output, and how such standards
should be applied across a variety of dif-
ferent types of tangible property.
These suggestions were extensively
considered, but the final regulations do not
adopt the suggestions to establish quan-
titative bright lines. Quantitative bright
lines, although objective, would produce
inconsistent results given the broad array
of factual settings where the betterment
rules apply. Instead, the final regulations
continue to rely on qualitative factors to
provide fair and equitable treatment for
all taxpayers in determining whether a
particular cost constitutes a betterment.
The final regulations clarify, how-
ever, that not every single quantitative or
qualitative factor listed in the betterment
standard applies to every type of property.
Whether any single factor applies to a
particular unit of property depends on the
nature of the property. For example, while
amounts paid for work performed on an
office building or a retail building may
clearly comprise a physical enlargement or
increase the capacity, efficiency, strength,
or quality of such building under certain
facts, it is unclear how to measure whether
work performed on an office building or
retail building increases the productiv-
ity or output of such buildings, as those
terms are generally understood. Thus,
the productivity and output factors would
not generally apply to buildings. On the
other hand, it is appropriate to evaluate
many items of manufacturing equipment
intermsofoutputorproductivityaswell
as size, capacity, efficiency, strength, and
quality. Accordingly, the final regulations
clarify that the applicability of each quan-
titative and qualitative factor depends on
the nature of the unit of property, and if an
addition or increase in a particular factor
cannot be measured in the context of a
specific type of property, then the factor is
October 21, 20133422013–43 I.R.B.

not relevant in determining whether there
has been a betterment to the property.
4. Application of Betterment Rule
Several commenters questioned the bet-
terment rule in the 2011 temporary regula-
tions that requires consideration of all facts
and circumstances, including the treatment
of the expenditures on a taxpayer’s ap-
plicable financial statement. One com-
menter questioned whether the treatment
of an expenditure on a taxpayer’s applica-
ble financial statement should be relevant
in determining whether an amount paid
results in a betterment and suggested re-
moval of this factor from the facts and cir-
cumstances test provided in the 2011 tem-
porary regulations. The IRS and the Trea-
sury Department recognize that taxpayers
may apply different standards for capital-
izing amounts on their applicable finan-
cial statements and such standards may not
be controlling for whether the activities
are betterments for Federal tax purposes.
Thus, the final regulations remove the tax-
payer’s treatment of the expenditure on its
financial statement as a factor to be consid-
ered in performing a betterment analysis
under the final regulations. In addition, the
final regulations omit the reference to the
taxpayer’s facts and circumstances in de-
termining whether amounts are paid for a
betterment to the taxpayer’s property. The
IRS and the Treasury Department believe
that an analysis of a taxpayer’s particu-
lar facts and circumstances is implicit in
the application of all the final regulations
governing improvements and need not be
specifically providedin the application of
the betterment rules.
The 2011 temporary regulations pro-
vided that, when an expenditure is ne-
cessitated by a particular event, the de-
termination of whether an expenditure is
for the betterment of a unit of property
is made by comparing the condition of
the property immediately after the expen-
diture with the condition of the property
immediately prior to the event necessi-
tating the expenditure. The IRS and the
Treasury Department received comments
requesting that the final regulations clarify
the application of the appropriate com-
parison rule for determining whether an
expenditure is for a betterment of a unit
of property. The final regulations retain
this general rule but clarify that the rule
applies when the event necessitating the
expenditure is eithernormal wear and tear
or damage to the unit of property during
the taxpayer’s use of the property. Thus,
the final regulations clarify that the appro-
priate comparison rule focuses on events
affecting the condition of the property and
not on business decisions made by tax-
payers. In addition, the final regulations
confirm that the rule does not apply to
wear, tear, or damage that occurs prior to
the taxpayer’s acquisition or use of the
property. In these situations, the ameliora-
tion of a material condition or defect rule
may apply.
5. Retail Store Refresh or Remodels
A substantial number of comments
were received with respect to the better-
ment examples in the 2011 temporary
regulations that addressretail store refresh
or remodel projects, requesting the addi-
tion of quantitative bright lines and the
inclusion of additional detail in the exam-
ples.
As discussed previously in this pre-
amble, the final regulations do not adopt
the suggestions to provide quantitative
bright lines in applying the betterment
rules. However, the final regulations in-
clude additional detail in a number of the
examples, including the examples related
to building refresh or remodels, illustrat-
ing distinctions between betterments and
maintenance activities when a taxpayer
undertakes multiple simultaneous activi-
ties on a building. To the extent the rules
in the final regulations present situations
that might be addressed through the IIR
program, taxpayers may pursue additional
guidance through the IIR process.
H.Restorations
1. Overview
The 2011 temporary regulations pro-
vided that an amount is paid to restore,
and therefore improve, a unit of property
if it meets one of six tests: (1) it is for
the replacement of a component of a unit
of property and the taxpayer has properly
deducted a loss for that component (other
than a casualty loss under §1.165–7); (2)
it is for the replacement of a component
of a unit of property and the taxpayer has
properly taken into account the adjusted
basis of the component in realizing gain or
loss resulting from thesaleorexchangeof
the component; (3) it is for the repair of
damage to a unit of property for which the
taxpayer has properly taken a basis adjust-
ment as a result of a casualty loss under
section 165, or relating to a casualty event
described in section 165 (“casualty loss
rule”); (4) it returns the unit of property to
its ordinarily efficient operating condition
if the property has deteriorated to a state of
disrepair and is no longer functional for its
intended use; (5) it results in the rebuilding
of the unit of property to a like-new condi-
tion after the end of its class life; or (6) it is
for the replacement of a major component
or a substantial structural part of the unit of
property (“major component rule”).
The IRS and the Treasury Department
received a number of comments regarding
the 2011 temporary regulations restoration
rules. The final regulations generally re-
tain the restoration standards set forth in
the 2011 temporary regulations but revise
both the major component rule and the ca-
sualty loss rule in response to comments.
2. Replacement of a Major Component or
Substantial Structural Part
a. Definition of major component and
substantial structural part
The 2011 temporary regulations pro-
vided that an amount paid for the replace-
ment of a major component or substan-
tial structural part of a unit of property is
an amount paid to restore (and, therefore,
improve) the unit of property. The deter-
mination of whether a component or part
was “major” or “substantial” depended on
the facts and circumstances, including both
qualitative and quantitative factors.
Commenters expressed concern that the
lack of a bright-line test or additional defi-
nitions would result in uncertainty and dis-
putes in applying the restoration rules con-
tained in the 2011 temporary regulations.
Several commenters stated that the stan-
dards provided in the 2011 temporary reg-
ulations were too subjective, and numer-
ous commenters requested that the final
regulations reintroduce a bright-line def-
inition of what constitutes a major com-
ponent or substantial structural part for
purposes of applying the restoration stan-
dards, particularly with regard to build-
ings. Several commenters suggested that
a fixed percentage of a building should
2013–43 I.R.B.343October 21, 2013

be defined as the major component. In
addition, commenters asked for clarifying
guidance or more examples, arguing that
the major component test of the 2011 tem-
porary regulations uses broad, undefined,
and subjective terms.
The final regulations retain the sub-
stantive rules of the 2011 temporary regu-
lations, but clarify the definition of major
component, and, more significantly, add
a new definition for major components
and substantial structural parts of build-
ings. Although the IRS and the Treasury
Department considered several bright-line
tests, none were found to fairly, equitably,
and in a readily implementable manner
distinguish between expenditures that con-
stitute restorations and expenditures that
constitute deductible repairs or mainte-
nance consistent with the case law and
administrative rulings in the area.
In many cases, particularly with regard
to buildings, establishing a clear threshold,
such as 30 percent of a defined amount,
would be unworkable. Largely due to the
complex nature of the property involved
and the fact that units of property include
assets placed in service in multiple tax-
able years, applying a fixed percentage to
a building structure or a building system
in a way that creates a consistent and eq-
uitable result proved exceedingly intricate
and complex, thereby failing to achieve
the simplifying objective of a bright line
test. The final regulations, therefore, do
not adopt any of the bright-line tests sug-
gested.
b. General rule for major component and
substantial structural part
To provide additional guidance for de-
termining what constitutes a major compo-
nent or substantial structural part, the final
regulations clarify the distinction between
a major component and a substantial struc-
tural part. Specifically, the final regula-
tions separate “major component,” which
focuses on the function of the component
in the unit of property, from “substantial
structural part,” which focuses on the size
of the replacement component in relation
to the unit of property. The final regula-
tions define a major component as a part
or combination of parts that performs a dis-
crete and critical function in the operation
of the unit of property. The final regula-
tions define a substantial structural part as
a part or combination of parts that com-
prises a large portion of the physical struc-
ture of the unit of property.
In response to comments, the final reg-
ulations retain, but also clarify, the excep-
tion to the major component rule. The
2011 temporary regulations provided that
the replacement of a minor component,
even though such component might affect
the function of the unit of property, gener-
ally would not, by itself, constitute a ma-
jor component. The exception was meant
to apply to relatively minor components,
such as a switch, which generally performs
a discrete function (turning property on
and off) and is critical to the operation of a
unit of property (that is, property will not
run without it). To provide additional clar-
ification regarding this exception, the final
regulations clarify that an incidental com-
ponent of a unit of property, even though
such component performs a discrete and
critical function in the operation of the unit
of property, generally will not, by itself,
constitute a major component.
c. Major component and substantial
structural part of buildings
The final regulations address the re-
quest for additional clarity regarding the
definition of major component for build-
ings by adding a new definition for ma-
jor components and substantial structural
parts of buildings. In the case of build-
ings, the final regulations provide that an
amount is for the replacement of a major
component or substantial structural part if
the replacement includes a part or combi-
nation of parts that (1) comprises a ma-
jor component or a significant portion of a
major component of the building structure
or any building system, or (2) comprises
a large portion of the physical structure of
the building structure or any building sys-
tem.
While the definition of major compo-
nent for buildings introduces an additional
level of analysis (a significant portion of
a major component) that must be applied
in determining whether an amount spent
on a building constitutes a restoration, the
rule provides an analytical framework and
reaches conclusions that are generally con-
sistent with the case law. Therefore, in
practice this framework should be readily
applicable for amountsspent on buildings.
In combination with the addition of a rou-
tine maintenance safe harbor for buildings,
the modifications to the section 168 dispo-
sition regulations, the safe harbor for small
taxpayers, and the addition and revision
of many examples, the revised definition
of major component for buildings should
relieve much of the controversy in deter-
mining whether the replacement of a major
component or a substantial structural part
of a unit of property is an amount paid to
restore a building.
3. Casualty Loss Rule
The 2011 temporary regulations pro-
vided that an amount is paid to restore a
unit of property if it is for the repair of
damage to the unit of property for which
the taxpayer has properly taken a basis ad-
justment as a result of a casualty loss un-
der section 165, or relating to a casualty
event described in section 165 (“casualty
loss rule”). Capitalization of restoration
costs is required under the casualty loss
rule, even when the amounts paid for the
repair exceed the adjusted basis remaining
in the property and regardless of whether
the amounts may otherwise qualify as re-
pair costs. The 2011 temporary regulations
recognized a taxpayer’s ability to deduct
a casualty loss under section 165 or, to
the extent eligible, to deduct the repair ex-
pense associated with the casualty damage.
But the 2011 temporary regulations did not
permit a taxpayer to deduct both amounts
arising from the same event in the same
taxable year.
Commenters requested that the final
regulations eliminate the casualty loss
rule. Commenters argued that recogni-
tion of a casualty loss under section 165
is irrelevant in determining whether the
costs to restore the damage resulting from
a casualty should be capitalized, and the
2011 temporary regulations should not
deny one tax benefit (the ability to deduct
repair costs) based on a taxpayer’s real-
ization of another tax benefit (the ability
to deduct a casualty loss). Similarly, com-
menters argued that the Code allows both
a casualty loss and a repair deduction, and
the IRS and the Treasury Department had
not offered any justification for denying a
deduction for the cost to repair damaged
property only because the taxpayer has
taken a casualty loss deduction. Com-
menters argued that the 2011 temporary
regulations penalize taxpayers that have
October 21, 20133442013–43 I.R.B.

suffered a casualty as a result of property
damage. Commenters suggested that the
casualty loss rule in the 2011 temporary
regulations results in similarly situated
taxpayers being treated differently, based
on whether an asset has adjusted basis at
the time of a casualty event. As an alterna-
tive to eliminating the casualty loss rule,
commenters requestedthat the final regu-
lations allow a taxpayer to elect to forego
recognizing the casualty loss and making
a corresponding adjustment to basis to
avoid application of the casualty loss rule.
The casualty loss rule in 2011 tempo-
rary regulations was based on the capital-
ization rule provided in section 263(a)(2),
which states that no deduction shall be al-
lowed for any amount expended in restor-
ingpropertyorinmakinggoodtheex-
haustion thereof for which an allowance
is or has been made. When property has
been damaged in a casualty and a loss for
such property has been claimed, amounts
paid to replace the damaged property are
incurred to restore property for which an
allowance has been made. Thus, under
section 263(a)(2), when the basis in re-
placed property has been recovered by the
taxpayer, capitalization of the replacement
property is appropriate.
Recognizing that such a rule can pro-
vide harsh results for a taxpayer with
valuable property with low adjusted ba-
sis that is destroyed in a casualty event,
considerable consideration was given to
the suggestion that the regulations pro-
vide an election to forgo a casualty loss
deduction. Ultimately, however, it was
concluded that the IRS and the Treasury
Department do not have the authority to
permit taxpayers to electively avoid the
basis adjustment requirement imposed by
section 1016(a). Section 1016(a) states
that “a proper adjustment in respect of the
property shall in all cases be made for . . .
losses, or other items, properly chargeable
to capital account . . ..” Therefore, even if
a taxpayer could choose to forgo claiming
a loss for property damage under section
165, section 1016 requires an adjustment
to the basis of the property because a loss
properly could be claimed.
In response to commenters’ sugges-
tions, the final regulations revise the
casualty loss rule to permit a deduction,
where otherwise permissible, for amounts
spent in excess of the adjusted basis of
the property damaged in a casualty event.
Thus, a taxpayer is still required to cap-
italize amounts paid to restore damage
to property for which the taxpayer has
properly recorded a basis adjustment, but
the costs required to be capitalized under
the casualty loss ruleare limited to the
excess of (1) the taxpayer’s basis adjust-
ments resulting from the casualty event,
over (2) the amount paid for restoration of
damage to the unit of property that also
constitutes a restoration under the other
criteria of §1.263(a)–3(k)(1) (excluding
the casualty loss rule). Casualty-related
expenditures in excessof this limitation
are not treated as restoration costs under
§1.263(a)–3(k)(1)(iii) and may be prop-
erly deducted if they otherwise constitute
ordinary and necessary business expenses
(for example, repair and maintenance
expenses) under section 162. The final
regulations contain several examples illus-
trating the casualty loss rule, including one
example that demonstrates the operation
of the new limitation on amounts required
to be capitalized.
4. Salvage Value Exception
Under the 2011 temporary regulations,
a restoration includes amounts paid for the
replacement of a component of a unit of
property when the taxpayer has properly
deducted a loss for that component (other
than a casualty loss under §1.165–7) and
for the replacement of a component of a
unit of property when the taxpayer has
properly taken into account the adjusted
basis of the component in realizing gain
or loss resulting from the sale or exchange
of the component. In response to com-
ments, the final regulations retain these
rules but provide an exception for property
that cannot be depreciated to an adjusted
basis of zero due to the application of sal-
vage value (for example, property placed
in service before 1981, and post–1980 as-
sets that do not qualify for the Acceler-
ated Cost Recovery System of former sec-
tion 168 (ACRS) or MACRS). When a loss
is properly deducted or the adjusted ba-
sis of the component is realized from a
sale or exchange, and the amount of loss
or basis adjustment is attributable only to
the remaining salvage value (the amount a
taxpayer is expected to receive in cash or
trade-in allowance upon disposition of an
asset at the end of its useful life) as com-
puted for Federal income tax purposes, a
taxpayer is not required to treat amounts
paid for the replacement of the component
as a restoration under §1.263(a)–3(k)(1)(i)
or (k)(1)(ii). Amounts subject to this ex-
ception must be evaluated under other pro-
visions of the regulations to determine if
the amounts are paid to improve tangible
property.
5. Rebuild to Like-New Condition
The 2011 temporary regulations pro-
vided that a unit of property is rebuilt
to a like-new condition if it is brought
to the status of new, rebuilt, remanufac-
tured, or similar status under the terms
of any federal regulatory guideline or the
manufacturer’s original specifications.
Commenters asked for clarification on
whether comprehensive maintenance pro-
grams, conducted according to manufac-
turer’s original specifications, constitute
rebuilding a unit of property to like-new
condition. The final regulations adopt
the standard provided in the 2011 tempo-
rary regulations but clarify that generally
a comprehensive maintenance program,
even though substantial, does not return a
unit of property to like-new condition.
I.Adaptation to a new or different use
The 2011 temporary regulations re-
quired a taxpayer to capitalize amounts
paid to adapt a unit of property to a new
or different use (that is, a use inconsistent
with the taxpayer’s intended ordinary use
at the time the property was originally
placed in service by the taxpayer). As
applied to buildings, the new or different
use standard is applied separately to the
building structure and its building sys-
tems. Commenters requested clarification
of the adaptation rules and additional ex-
amples. Commenters also asked that, for
specific industries, the regulations provide
that changes to facilities in response to a
change in product mix, a reallocation of
floor space, the need to rebrand, or the
introduction of a new product line do not
constitute a new or different use.
The final regulations retain the substan-
tive rules of the 2011 temporary regula-
tions but add additional examples to il-
lustrate the rules. The final regulations
provide that if an amount adapts the unit
of property in a manner inconsistent with
the taxpayer’s intended ordinary use of
the property when placed in service, the
2013–43 I.R.B.345October 21, 2013

amount must be capitalized as an adapta-
tion of the unit of property to a new or dif-
ferent use. In response to comments, two
new examples address circumstances in
which part of a retail building unit of prop-
erty is converted to provide new services
or products. However, providing tailored
guidance for specific industries or specific
types of property (for example, retail sales
facilities) is not appropriate for broadly ap-
plicable guidance. Specific industry guid-
ance is better addressed through the IIR
program.
VII.Optional Regulatory Accounting
Method
The 2011 temporary regulations pro-
vided an optional regulatory method,
which permitted certain regulated taxpay-
ers to follow the method of accounting
they used for regulatory accounting pur-
poses in determining whether an amount
paid improves property. For purposes of
the optional method, a taxpayer in a regu-
lated industry is a taxpayer subject to the
regulatory accounting rules of the Federal
Energy Regulatory Commission (FERC),
the Federal Communications Commis-
sion (FCC), or the Surface Transportation
Board (STB). A taxpayer that uses the
regulatory accounting method does not
apply the rules under sections 162, 212,
or 263(a) in determining whether amounts
paid to repair, maintain, or improve prop-
erty are capital expenditures or deductible
expenses. Section 263A continues to ap-
plytocostsrequiredtobecapitalizedto
property produced by the taxpayer or to
property acquired for resale.
The IRS and the Treasury Department
received no comments on this methodol-
ogy, and the final regulations retain the rule
from the 2011 temporary regulations, with
one modification. The final regulations
modify the description of the regulatory
accounting method to clarify that, for pur-
poses of determining whether an amount
is for a capital expenditure, an eligible tax-
payer must apply the method of accounting
that it is required to follow by FERC, FCC,
or STB (whichever is applicable).
VIII.Election to Capitalize Repair and
Maintenance Costs
The 2011 temporary regulations did
not contain an election for taxpayers to
capitalize expenditures made with respect
to tangible property that would otherwise
be deductible under these regulations.
Commenters requested that, to reduce un-
certainty in applying subjective standards
and to reduce administrative burden, the
final regulations include an election to
capitalize repair and maintenance expen-
ditures as improvements if the taxpayer
treats such costs as capital expenditures
for financial accounting purposes. In
response to these comments as well as
in recognition of the significant admin-
istrative burden reduction achieved by
permitting a taxpayer to follow for Federal
income tax purposes the capitalization
policies used for its books and records, the
final regulations permit a taxpayer to elect
to treat amounts paid during the taxable
year for repair and maintenance to tangi-
ble property as amounts paid to improve
that property and as an asset subject to the
allowance for depreciation, as long as the
taxpayer incurs the amounts in carrying
on a trade or business and the taxpayer
treats the amounts as capital expenditures
on its books and records used for regu-
larly computing income. Under the final
regulations, a taxpayer that elects this
treatment must apply the election to all
amounts paid for repair and maintenance
to tangible property that it treats as capi-
tal expenditures on its books and records
in that taxable year. A taxpayer making
the election must begin to depreciate the
cost of such improvements when the im-
provements are placed in service by the
taxpayer under the applicable provisions
of the Code and regulations. The election
is made by attaching a statement to the
taxpayer’s timely filed original Federal
tax return (including extensions) for the
taxable year in which the improvement is
placed in service. Once made, the election
may not be revoked.
A taxpayer that capitalizes repair and
maintenance costs under the election is
still eligible to apply thede minimissafe
harbor, the safe harbor for small taxpayers,
and the routine maintenance safe harbor to
repair and maintenance costs that are not
treated as capital expenditures on its books
and records.
IX.Applicability Dates
The final regulations generally apply to
taxable years beginning on or after January
1, 2014. However, certain provisions of
the final regulations only apply to amounts
paid or incurred in taxable years beginning
on or after January 1, 2014. For exam-
ple, thede minimissafe harbor election un-
der §1.263(a)–1(f) only applies to amounts
paid or incurred for tangible property after
January 1, 2014, for taxable years begin-
ning on or after January 1, 2014.
Alternatively, a taxpayer may generally
choose to apply the final regulations to tax-
able years beginning on or after January
1, 2012. For taxpayers choosing this early
application, certain provisions of the final
regulations only apply to amounts paid or
incurred in taxable years beginning on or
after January 1, 2012. For example, for
these taxpayers, thede minimissafe har-
bor election only applies to amounts paid
or incurred for tangible property after Jan-
uary 1, 2012, for taxable years beginning
on or after January 1, 2012.
For taxpayers choosing to apply the fi-
nal regulations to taxable years beginning
on or after January 1, 2012, or where appli-
cable, to amounts paid or incurred in tax-
able years beginning on or after January 1,
2012, the final regulations provide transi-
tion relief for taxpayers that did not make
the certain elections (for example, the elec-
tion to apply thede minimissafe harbor
or the election to apply the safe harbor for
small taxpayers) on their timely filed orig-
inal Federal tax return for their 2012 or
2013 taxable year (the applicable taxable
year). Specifically, for taxable years be-
ginning on or after January 1, 2012, and
ending on or before September 19, 2013,
a taxpayer is permitted to make these elec-
tions by filing an amended Federal tax re-
turn (including any applicable statements)
for the applicable taxable year on or be-
fore 180 days from the due date includ-
ing extensions of the taxpayer’s Federal
tax return for the applicable taxable year,
notwithstanding that the taxpayer may not
have extended the due date.
Finally, a taxpayer may also choose to
apply the 2011 temporary regulations to
taxable years beginning on or after Jan-
uary 1, 2012, and before January 1, 2014.
For taxpayers choosing to apply the tem-
porary regulations to these taxable years,
certain provisions of the temporary regu-
lations only apply to amounts paid or in-
curred in taxable years beginning on or af-
ter January 1, 2012, and before January 1,
2014.
October 21, 20133462013–43 I.R.B.

X.Change in Method of Accounting
The IRS and the Treasury Department
received several comments regarding the
procedures that a taxpayer should utilize to
change its method ofaccounting to comply
with the regulations. Several commenters
favored the use of a cut-off method, pri-
marily for reasons of administrative con-
venience. However, other commenters as-
serted that any change in method of ac-
counting must include a section 481(a) ad-
justment.
The final regulations provide that, ex-
cept as otherwise stated, a change to com-
ply with the final regulations is a change in
method of accounting to which the provi-
sions of sections 446 and 481 and the ac-
companying regulations apply. A taxpayer
seeking to change to a method of account-
ing permitted in the final regulations must
secure the consent of the Commissioner in
accordance with §1.446–1(e) and follow
the administrative procedures issued under
§1.446–1(e)(3)(ii) for obtaining the Com-
missioner’s consent to change its account-
ing method. In general, a taxpayer seek-
ing a change in method of accounting to
comply with these regulations must take
into account a full adjustment under sec-
tion 481(a).
The imposition of a section 481(a) ad-
justment for a change in method of ac-
counting to conform to the final regula-
tions provides for a uniform and consis-
tent rule for all taxpayers and ultimately
reduces the administrative burdens on tax-
payers and the IRS in enforcing the re-
quirements of section 263(a). Although
the IRS and the Treasury Department rec-
ognize that requiring a section 481(a) ad-
justment may place a burden on taxpayers
to calculate reasonable adjustments, tax-
payers have shown a willingness and abil-
ity to make these calculations in request-
ing method changes after the publication
of the 2008 proposed regulations and af-
ter the publication of the 2011 temporary
regulations. In addition, taxpayers and the
IRS routinely reach agreements on calcu-
lation methodologies and amounts.
Separate procedures will be provided
under which taxpayers may obtain auto-
matic consent for a taxable year beginning
on or after January 1, 2012, to change to
a method of accounting provided in the fi-
nal regulations. Although a taxpayer seek-
ing a change in method of accounting to
comply with these regulations generally
must take into account a full adjustment
under section 481(a), it is anticipated that
for the specific situation where a taxpayer
seeks to change to a method of account-
ing that is applicable only to amounts paid
or incurred in taxable years beginning on
or after January 1, 2014, a limited section
481(a) adjustment will apply, taking into
account only amounts paid or incurred in
taxable years beginning on or after January
1, 2014, or at a taxpayer’s option, amounts
paid or incurred in taxable years beginning
on or after January 1, 2012.
Special Analyses
It has been determined that this Trea-
sury decision is not a significant regula-
tory action as defined in Executive Order
12866, as supplemented by Executive Or-
der 13563. Therefore, a regulatory assess-
ment is not required. It also has been deter-
mined that section 553(b) of the Adminis-
trative Procedure Act(5 U.S.C. chapter 5)
does not apply to these regulations.
Pursuant to the Regulatory Flexibil-
ity Act (5 U.S.C. chapter 6), it is hereby
certified that these final regulations will
not have a significant economic impact
on a substantial number of small entities.
This regulation affects all small business
taxpayers. While a collection of infor-
mation is required by this regulation in
§§1.263(a)–1(f)(5), 1.263(a)–2(h)(6), and
1.263(a)–3(n), this collection will not have
a significant economic impact on small
entities. This information is required for
a taxpayer to elect to use thede minimis
safe harbor, to elect a safe harbor for de-
termining the treatment of amounts related
to buildings owned or leased by small
taxpayers, and to elect to capitalize cer-
tain repair and maintenance costs. These
elections were provided in the regulations
in response to comment letters submitted
on behalf of small business taxpayers re-
questing that these types of provisions be
added to the regulations to assist small
businesses. All of these elections are vol-
untary, beneficial, and were designed to
simplify the application of sections 162
and 263(a) to small taxpayers. The provi-
sions require a taxpayer to file a statement
with the taxpayer’s timely filed original
tax return to inform the IRS that the tax-
payer is electing to use these provisions.
The estimated time to prepare a statement
should not exceed 15 minutes, and the
filing of the statement allows the taxpayer
to receive the beneficial treatment for the
amounts that qualify for the statement.
Based on these facts, a regulatory flexibil-
ity analysis under Regulatory Flexibility
Act (5 U.S.C. chapter 6) is not required.
Pursuant to section 7805(f) of the Code,
this regulation was submitted to the Chief
Counsel for Advocacy of the Small Busi-
ness Administration for comment on its
impact on small business.

Adoption of Amendments to the
Regulations
Accordingly, 26 CFR parts 1 and 602
are amended as follows:
PART 1—INCOME TAXES
Paragraph 1. The authority citation for
part 1 continues to read in part as follows:
Authority: 26 U.S.C. 7805 * * *
Par. 2. Section 1.162–3 is revised to
read as follows:
§1.162–3 Materials and supplies.
(a)In general—(1)Non-incidental ma-
terials and supplies. Except as provided
in paragraphs (d), (e), and (f) of this sec-
tion, amounts paid to acquire or produce
materials and supplies (as defined in para-
graph (c) of this section) are deductible in
the taxable year in which the materials and
supplies are first used in the taxpayer’s op-
erations or are consumed in the taxpayer’s
operations.
2013–43 I.R.B.347October 21, 2013

(2)Incidental materials and supplies.
Amounts paid to acquire or produce inci-
dental materials and supplies (as defined
in paragraph (c) of this section) that are
carried on hand and for which no record
of consumption is kept or of which phys-
ical inventories at the beginning and end
of the taxable year are not taken, are de-
ductible in the taxable year in which these
amounts are paid, provided taxable income
is clearly reflected.
(3)Use or consumption of rotable and
temporary spare parts. Except as provided
in paragraphs (d), (e), and (f) of this sec-
tion, for purposes of paragraph (a)(1) of
this section, rotable and temporary spare
parts (defined under paragraph (c)(2) of
this section) are first used in the taxpayer’s
operations or are consumed in the tax-
payer’s operations in the taxable year in
which the taxpayer disposes of the parts.
(b)Coordination with other provisions
of the Internal Revenue Code. Nothing in
this section changes the treatment of any
amount that is specifically provided for un-
der any provision of the Internal Revenue
Code (Code) or regulations other than sec-
tion 162(a) or section 212 and the regula-
tions under those sections. For example,
see §1.263(a)–3, which requires taxpay-
ers to capitalize amounts paid to improve
tangible property and section 263A and
the regulations under section 263A, which
require taxpayers to capitalize the direct
and allocable indirectcosts, including the
cost of materials and supplies, of prop-
erty produced by the taxpayer and property
acquired for resale. See also §1.471–1,
which requires taxpayers to include in in-
ventory certain materials and supplies.
(c)Definitions—(1)Materials and sup-
plies. For purposes of this section,mate-
rials and suppliesmeans tangible property
that is used or consumed in the taxpayer’s
operations that is not inventory and that—
(i) Is a component acquired to maintain,
repair, or improve a unit of tangible prop-
erty (as determined under §1.263(a)–3(e))
owned, leased, or serviced by the taxpayer
and that is not acquired as part of any sin-
gle unit of tangible property;
(ii) Consists of fuel, lubricants, water,
and similar items, reasonably expected to
be consumed in 12 months or less, begin-
ning when used in the taxpayer’s opera-
tions;
(iii) Is a unit of property as determined
under §1.263(a)–3(e) that has an economic
useful life of 12 months or less, beginning
when the property is used or consumed in
the taxpayer’s operations;
(iv) Is a unit of property as determined
under §1.263(a)–3(e) that has an acqui-
sition cost or production cost (as deter-
mined under section 263A) of $200 or
less (or other amount as identified in pub-
lished guidance in theFederal Register
or in the Internal Revenue Bulletin (see
§601.601(d)(2)(ii)(b)ofthischapter);or
(v) Is identified in published guid-
ance in theFederal Registeror in
the Internal Revenue Bulletin (see
§601.601(d)(2)(ii)(b)ofthischapter)as
materials and supplies for which treatment
is permitted under this section.
(2)Rotable and temporary spare parts.
For purposes of this section, rotable spare
parts are materials and supplies under
paragraph (c)(1)(i) of this section that are
acquired for installation on a unit of prop-
erty, removable from that unit of property,
generally repaired or improved, and either
reinstalled on the same or other property
or stored for later installation. Tempo-
rary spare parts are materials and supplies
under paragraph (c)(1)(i) of this section
that are used temporarily until a new or
repaired part can be installed and then are
removed and stored for later installation.
(3)Standby emergency spare parts.
Standby emergency spare parts are materi-
als and supplies under paragraph (c)(1)(i)
of this section that are—
(i) Acquired when particular machinery
or equipment is acquired (or later acquired
and set aside for use in particular machin-
ery or equipment);
(ii) Set aside for use as replacements
to avoid substantial operational time loss
caused by emergencies due to particular
machinery or equipment failure;
(iii) Located at or near the site of the
installed related machinery or equipment
so as to be readily available when needed;
(iv) Directly related to the particular
machinery or piece of equipment they
serve;
(v) Normally expensive;
(vi) Only available on special order
and not readily available from a vendor or
manufacturer;
(vii) Not subject to normal periodic re-
placement;
(viii) Not interchangeable in other ma-
chines or equipment;
(x) Not acquired in quantity (generally
only one is on hand for each piece of ma-
chinery or equipment); and
(xi) Not repaired and reused.
(4)Economic useful life—(i)General
rule. The economic useful life of a unit of
property is not necessarily the useful life
inherent in the property but is the period
over which the property may reasonably be
expected to be useful to the taxpayer or, if
the taxpayer is engaged in a trade or busi-
ness or an activity for the production of in-
come, the period over which the property
may reasonably be expected to be useful
to the taxpayer in its trade or business or
for the production of income, as applica-
ble. See §1.167(a)–1(b) for the factors to
be considered in determining this period.
(ii)Taxpayers with an applicable finan-
cial statement. For taxpayers with an ap-
plicable financial statement (as defined in
paragraph (c)(4)(iii) of this section), the
economic useful life of a unit of prop-
erty, solely for the purposes of applying the
provisions of paragraph (c)(4) of this sec-
tion, is the useful life initially used by the
taxpayer for purposes of determining de-
preciation in its applicable financial state-
ment, regardless of any salvage value of
the property. If a taxpayer does not have
an applicable financial statement for the
taxable year in which a unit of property
was originally acquired or produced, the
economic useful life of the unit of prop-
erty must be determined under paragraph
(c)(4)(i) of this section. Further, if a tax-
payer treats amounts paid for a unit of
property as an expense in its applicable fi-
nancial statement on a basis other than the
useful life of the property or if a taxpayer
does not depreciate the unit of property
on its applicable financial statement, the
economic useful life of the unit of prop-
erty must be determined under paragraph
(c)(4)(i) of this section. For example, if
a taxpayer has a policy of treating as an
expense on its applicable financial state-
ment amounts paid for a unit of property
costing less than a certain dollar amount,
notwithstanding that the unit of property
has a useful life of more than one year, the
economic useful life of the unit of prop-
erty must be determined under paragraph
(c)(4)(i) of this section.
(iii)Definition of applicable finan-
cial statement. The taxpayer’s applicable
financial statement is the taxpayer’s fi-
nancial statement listed in paragraphs
October 21, 20133482013–43 I.R.B.

(c)(4)(iii)(A) through (C) of this section
that has the highest priority (including
within paragraph (c)(4)(iii)(B) of this sec-
tion). The financial statements are, in
descending priority—
(A) A financial statement required to
be filed with the Securities and Exchange
Commission (SEC) (the 10–K or the An-
nual Statement to Shareholders);
(B) A certified audited financial state-
ment that is accompanied by the report of
an independent certified public accountant
(or in the case of a foreign entity, by the
report of a similarly qualified independent
professional), that is used for—
(1) Credit purposes;
(2) Reporting to shareholders, partners,
or similar persons; or
(3) Any other substantial non-tax pur-
pose; or
(C) A financial statement (other than
a tax return) required to be provided to
the federal or a state government or any
federal or state agency (other than the SEC
or the Internal Revenue Service).
(5)Amount paid. For purposes of this
section, in the case of a taxpayer using
an accrual method of accounting, the
termsamount paidandpaymentmean a
liability incurred (within the meaning of
§1.446–1(c)(1)(ii)). A liability may not
be taken into account under this section
prior to the taxable year during which the
liability is incurred.
(6)Produce. For purposes of this sec-
tion,producemeans construct, build, in-
stall, manufacture, develop, create, raise,
or grow. This definition is intended to have
the same meaning as the definition used
for purposes of section 263A(g)(1) and
§1.263A–2(a)(1)(i), except that improve-
ments are excluded from the definition in
this paragraph (c)(6) and are separately
defined and addressed in §1.263(a)–3.
Amounts paid to produce materials and
supplies are subject to section 263A.
(d)Election to capitalize and depreci-
ate certain materials and supplies—(1)In
general. A taxpayer may elect to treat as
a capital expenditure and to treat as an as-
set subject to the allowance for deprecia-
tion the cost of any rotable spare part, tem-
porary spare part, or standby emergency
spare part as defined in paragraph (c)(2) or
(c)(3) of this section. Except as specified
in paragraph (d)(2) of this section, an elec-
tion made under this paragraph (d) applies
to amounts paid during the taxable year to
acquire or produce any rotable, temporary,
or standby emergency spare part to which
paragraph (a) of this section would apply
(but for the election under this paragraph
(d)). Any property for which this election
is made shall not be treated as a material or
a supply.
(2)Exceptions. A taxpayer may not
elect to capitalize and depreciate under
paragraph (d) of this section any amount
paid to acquire or produce a rotable, tem-
porary, or standby emergency spare part
defined in paragraph (c)(2) or (c)(3) of this
section if—
(i) The rotable, temporary, or standby
emergency spare part is intended to be used
as a component of a unit of property under
paragraph (c)(1)(iii), (iv), or (v) of this sec-
tion;
(ii) The rotable, temporary, or standby
emergency spare part is intended to be used
as a component of a property described in
paragraph (c)(1)(i) and the taxpayer cannot
or has not elected to capitalize and depreci-
ate that property under this paragraph (d);
or
(iii) The amount is paid to acquire or
produce a rotable or temporary spare part
and the taxpayer uses the optional method
of accounting for rotable and temporary
spare parts under paragraph (e) to of this
section.
(3)Manner of electing. A taxpayer
makes the election under paragraph (d) of
this section by capitalizing the amounts
paid to acquire or produce a rotable, tem-
porary, or standby emergency spare part
in the taxable year the amounts are paid
and by beginning to recover the costs when
the asset is placed in service by the tax-
payer for the purposes of determining de-
preciation under the applicable provisions
of the Internal Revenue Code and the Trea-
sury Regulations. See §1.263(a)–2 for the
treatment of amounts paid to acquire or
produce real or personal tangible property.
A taxpayer must make this election in its
timely filed original Federal tax return (in-
cluding extensions) for the taxable year the
asset is placed in service by the taxpayer
for purposes of determining depreciation.
See §§301.9100–1 through 301.9100–3 of
this chapter for the provisions governing
extensions of time to make regulatory elec-
tions. In the case of an S corporation or a
partnership,theelectionismadebytheS
corporation or partnership, and not by the
shareholders or partners. A taxpayer may
make an election for each rotable, tempo-
rary, or standby emergency spare part that
qualifies for the election under this para-
graph (d). A taxpayer may revoke an elec-
tion made under this paragraph (d) with re-
spect to a rotable, temporary, or standby
emergency spare part only by filing a re-
quest for a private letter ruling and ob-
taining the Commissioner’s consent to re-
voke the election. The Commissioner may
grant a request to revoke this election if
the taxpayer acted reasonably and in good
faith and the revocation will not prejudice
the interests of the Government. See gen-
erally §301.9100–3 of this chapter. The
manner of electing and revoking the elec-
tion to capitalize under this paragraph (d)
may be modified through guidance of gen-
eral applicability (see§§601.601(d)(2) and
601.602 of this chapter). An election may
not be made or revoked through the filing
of an application for change in account-
ing method or, before obtaining the Com-
missioner’s consent to make the late elec-
tion or to revoke the election, by filing an
amended Federal tax return.
(e)Optional method of accounting for
rotable and temporary spare parts—(1)In
general. This paragraph (e) provides an
optional method of accounting for rotable
and temporary spare parts (the optional
method for rotable parts). A taxpayer may
use the optional method for rotable parts,
instead of the general rule under paragraph
(a)(3) of this section, to account for its
rotable and temporary spare parts as de-
fined in paragraph (c)(2) of this section.
A taxpayer that uses the optional method
for rotable parts must use this method for
all of its pools of rotable and temporary
spare parts used in the same trade or busi-
ness and for which it uses this method for
its books and records. If a taxpayer uses
the optional method for rotable and tempo-
rary spare parts for pools of rotable or tem-
porary spare parts for which the taxpayer
does not use the optional method for its
book and records, then the taxpayer must
use the optional method for all its pools
of rotable spare parts in the same trade or
business. The optional method for rotable
parts is a method of accounting under sec-
tion 446(a). Under the optional method for
rotable parts, the taxpayer must apply the
rules in this paragraph (e) to each rotable
or temporary spare part(part) upon the tax-
payer’s initial installation, removal, repair,
2013–43 I.R.B.349October 21, 2013

maintenance or improvement, reinstalla-
tion, and disposal of each part.
(2)Description of optional method for
rotable parts—(i)Initial installation.The
taxpayer must deduct the amount paid to
acquire or produce the part in the taxable
year that the part is first installed on a unit
of property for use in the taxpayer’s oper-
ations.
(ii)Removalfromunitofproperty.In
each taxable year in which the part is re-
moved from a unit of property to which it
was initially or subsequently installed, the
taxpayer must—
(A) Include in gross income the fair
market value of the part; and
(B) Include in the basis of the part the
fair market value of the part included in in-
come under paragraph (e)(2)(ii)(A) of this
section and the amount paid to remove the
part from the unit of property.
(iii)Repair, maintenance, or improve-
ment of part. The taxpayer may not cur-
rently deduct and must include in the basis
of the part any amounts paid to maintain,
repair, or improve the part in the taxable
year these amounts are paid.
(iv)Reinstallation of part.Thetax-
payer must deduct the amounts paid to re-
install the part and those amounts included
in the basis of the part under paragraphs
(e)(2)(ii)(B) and (e)(2)(iii) of this section,
to the extent that those amounts have not
been previously deducted under this para-
graph (e)(2)(iv), in the taxable year that the
part is reinstalled on a unit of property.
(v)Disposal of the part. The tax-
payer must deduct the amounts included
in the basis of the part under paragraphs
(e)(2)(ii)(B) and (e)(2)(iii) of this section,
to the extent that those amounts have not
been previously deducted under paragraph
(e)(2)(iv) of this section, in the taxable
year in which the part is disposed of by the
taxpayer.
(f)Application of de minimis safe har-
bor. If a taxpayer elects to apply thede
minimissafe harbor under §1.263(a)–1(f)
to amounts paid for the production or ac-
quisition of tangible property, then the
taxpayer must apply thede minimissafe
harbor to amounts paid for all materials
and supplies that meet the requirements
of §1.263(a)–1(f), except for those mate-
rials and supplies that the taxpayer elects
to capitalize and depreciate under para-
graph (d) of this section or for which
the taxpayer properly uses the optional
method of accounting for rotable and tem-
porary spare parts under paragraph (e)
of this section. If the taxpayer properly
applies thede minimissafe harbor under
§1.263(a)–1(f) to amounts paid for ma-
terials and supplies, then these amounts
are not treated as amounts paid for mate-
rials and supplies under this section. See
§1.263(a)–1(f)(5) for the time and manner
of electing thede minimissafe harbor and
§1.263(a)–1(f)(3)(iv) for the treatment of
safe harbor amounts.
(g)Sale or disposition of materials and
supplies. Upon sale or other disposition,
materials and supplies as defined in this
section are not treated as a capital asset
under section 1221 or as property used in
the trade or business under section 1231.
Any asset for which the taxpayer makes
the election to capitalize and depreciate
under paragraph (d) of this section shall
not be treated as a material or supply, and
the recognition and character of the gain
or loss for such depreciable asset are deter-
mined under other applicable provisions of
the Code.
(h)Examples. The rules of this section
areillustratedbythefollowingexamples,
in which it is assumed, unless otherwise
stated, that the property is not an incidental
material or supply, that the taxpayer com-
putes its income on a calendar year basis,
that the taxpayer does not make the elec-
tion to apply paragraph (d) of this section,
or use the method of accounting described
in paragraph (e) of this section, and that
the taxpayer has not elected to apply thede
minimissafe harbor under §1.263(a)–1(f).
The following examples illustrate only the
application of thissection and, unless oth-
erwise stated, do notaddress the treatment
under other provisions of the Code (for ex-
ample, section 263A).
Example 1.Non-rotable components. A owns a
fleet of aircraft that it operates in its business. In Year
1, A purchases a stock of spare parts, which it uses
to maintain and repair itsaircraft. A keeps a record
of consumption of these spare parts. In Year 2, A
uses the spare parts for the repair and maintenance
of one of its aircraft. Assume each aircraft is a unit
of property under §1.263(a)–3(e) and that spare parts
are not rotable or temporary spare parts under para-
graph (c)(2) of this section. Assume these repair and
maintenance activities do not improve the aircraft un-
der §1.263(a)–3. These parts are materials and sup-
plies under paragraph (c)(1)(i) of this section because
they are components acquired and used to maintain
and repair A’s aircraft. Under paragraph (a)(1) of this
section, the amounts that A paid for the spare parts
in Year 1 are deductible in Year 2, the taxable year
in which the spare parts are first used to repair and
maintain the aircraft.
Example 2.Rotable spare parts; disposal
method
. B operates a fleet of specialized vehicles
that it uses in its service business. Assume that each
vehicle is a unit of property under §1.263(a)–3(e).
At the time that it acquires a new type of vehicle, B
also acquires a substantial number of rotable spare
partsthatitwillkeeponhandtoquicklyreplace
similar parts in B’s vehicles as those parts break
down or wear out. These rotable parts are removable
from the vehicles and are repaired so that they can
be reinstalled on the same or similar vehicles. In
Year 1, B acquires several vehicles and a number of
rotable spare parts to be used as replacement parts in
these vehicles. In Year 2, B repairs several vehicles
by using these rotable spare parts to replace worn or
damaged parts. In Year 3, B removes these rotable
spare parts from its vehicles, repairs the parts, and
reinstalls them on other similar vehicles. In Year 5,
B can no longer use the rotable parts it acquired in
Year 1 and disposes of them as scrap. Assume that
B does not improve any of the rotable spare parts
under §1.263(a)–3. Under paragraph (c)(1)(i) of this
section, the rotable spare parts acquired in Year 1 are
materials and supplies. Under paragraph (a)(3) of
this section, rotable spare parts are generally used or
consumed in the taxable year in which the taxpayer
disposes of the parts. Therefore, under paragraph
(a)(1) of this section, the amounts that B paid for the
rotable spare parts in Year 1 are deductible in Year 5,
the taxable year in which B disposes of the parts.
Example 3.Rotable spare parts; application of
optional method of accounting
. C operates a fleet of
specialized vehicles that it uses in its service business.
Assume that each vehicle is a unit of property under
§1.263(a)–3(e). At the time that it acquires a new
type of vehicle, C also acquires a substantial number
of rotable spare parts that it will keep on hand to re-
place similar parts in C’s vehicles as those parts break
down or wear out. These rotable parts are removable
from the vehicles and are repaired so that they can be
reinstalled on the same or similar vehicles. C uses
the optional method of accounting for all its rotable
and temporary spare parts under paragraph (e) of this
section. In Year 1, C acquires several vehicles and
a number of rotable spare parts (the “Year 1 rotable
parts”) to be used as replacement parts in these vehi-
cles. In Year 2, C repairs several vehicles and uses
the Year 1 rotable parts to replace worn or damaged
parts. In Year 3, C pays amounts to remove these Year
1 rotable parts from its vehicles. In Year 4, C pays
amounts to maintain, repair, or improve the Year 1
rotable parts. In Year 5, C pays amounts to reinstall
the Year 1 rotable parts on other similar vehicles. In
Year 8, C removes the Year 1 rotable parts from these
vehicles and stores these parts for possible later use.
In Year 9, C disposes of the Year 1 rotable parts. Un-
der paragraph (e) of this section, C must deduct the
amounts paid to acquire and install the Year 1 rotable
parts in Year 2, the taxable year in which the rotable
partsarefirstinstalledbyCinC’svehicles.InYear
3, when C removes the Year 1 rotable parts from its
vehicles, C must include in its gross income the fair
market value of each part. Also, in Year 3, C must in-
clude in the basis of each Year 1 rotable part the fair
market value of the rotable part and the amount paid
to remove the rotable part from the vehicle. In Year
4, C must include in the basis of each Year 1 rotable
October 21, 20133502013–43 I.R.B.

part the amounts paid to maintain, repair, or improve
each rotable part. In Year 5, the year that C reinstalls
the Year 1 rotable parts (as repaired or improved) in
other vehicles, C must deduct the reinstallation costs
and the amounts previously included in the basis of
each part. In Year 8, the year that C removes the Year
1 rotable parts from the vehicles, C must include in
income the fair market value of each rotable part re-
moved. In addition, in Year 8, C must include in the
basis of each part the fair market value of that part and
the amount paid to remove each rotable part from the
vehicle. In Year 9, the year that C disposes of the Year
1 rotable parts, C may deduct the amounts remaining
in the basis of each rotable part.
Example 4.Rotable part acquired as part of a
single unit of property; not material or supply
.D
operates a fleet of aircraft. In Year 1, D acquires
a new aircraft, which includes two new aircraft en-
gines. The aircraft costs $500,000 and has an eco-
nomic useful life of more than 12 months, beginning
when it is placed in service. In Year 5, after the air-
craft is operated for several years in D’s business, D
removes the engines from the aircraft, repairs or im-
proves the engines, and either reinstalls the engines
on a similar aircraft or stores the engines for later re-
installation. Assume the aircraft purchased in Year 1,
including its two engines, is a unit of property under
§1.263(a)–3(e). Because the engines were acquired
as part of the aircraft, a single unit of property, the
engines are not materials or supplies under paragraph
(c)(1)(i) of this section nor rotable or temporary spare
parts under paragraph (c)(2) of this section. Accord-
ingly, D may not apply the rules of this section to
the aircraft engines upon the original acquisition of
the aircraft nor after the removal of the engines from
the aircraft for use in the same or similar aircraft.
Rather, D must apply the rules under §§1.263(a)–2
and 1.263(a)–3 to the aircraft, including its engines,
to determine the treatment of amounts paid to acquire,
produce, or improve the unit of property.
Example 5.Consumable property. E operates a
fleet of aircraft that carries freight for its customers. E
has several storage tanks on its premises, which hold
jet fuel for its aircraft. Assume that once the jet fuel
is placed in E’s aircraft, the jet fuel is reasonably ex-
pected to be consumed within 12 months or less. On
December 31, Year 1, E purchases a two-year sup-
plyofjetfuel. InYear2,Eusesaportionofthejet
fuel purchased on December 31, Year 1, to fuel the
aircraft used in its business. The jet fuel that E pur-
chased in Year 1 is a material or supply under para-
graph (c)(1)(ii) of this section because it is reason-
ably expected to be consumed within 12 months or
less from the time it is placed in E’s aircraft. Under
paragraph (a)(1) of this section, E may deduct in Year
2 the amounts paid for the portion of jet fuel used in
the operation of E’s aircraft in Year 2.
Example 6.Unit of property that costs $200 or
less
. F operates a business that rents out a variety of
small individual items to customers (rental items). F
maintains a supply of rental items on hand. In Year
1, F purchases a large quantity of rental items to use
in its rental business. Assume that each rental item
is a unit of property under §1.263(a)–3(e) and costs
$200 or less. In Year 2, F begins using all the rental
items purchased in Year 1 by providing them to cus-
tomers of its rental business. F does not sell or ex-
change these items on established retail markets at
any time after the items are used in the rental busi-
ness. The rental items are materials and supplies un-
der paragraph (c)(1)(iv) of this section. Under para-
graph (a)(1) of this section, the amounts that F paid
for the rental items in Year 1 are deductible in Year
2, the taxable year in which the rental items are first
used in F’s business.
Example 7.Unit of property that costs $200 or
less
. G provides billing services to its customers. In
Year 1, G pays amounts to purchase 50 scanners to be
used by its employees. Assume each scanner is a unit
of property under §1.263(a)–3(e) and costs less than
$200. In Year 1, G’s employees begin using 35 of
the scanners, and F stores the remaining 15 scanners
for use in a later taxable year. The scanners are ma-
terials and supplies under paragraph (c)(1)(iv) of this
section. Under paragraph (a)(1) of this section, the
amounts G paid for 35 of the scanners are deductible
in Year 1, the taxable year in which G first uses each
of those scanners. The amounts that G paid for each
of the remaining 15 scanners are deductible in the tax-
able year in which each machine is first used in G’s
business.
Example 8.Materials and supplies that cost less
than $200; de minimis safe harbor
. Assume the same
factsasin
Example 7except that G’s scanners qualify
for the
de minimissafe harbor under §1.263(a)–1(f),
and G properly elects to apply the
de minimissafe
harbor under §1.263(a)–1(f) to amounts paid in Year
1. G must apply the
de minimissafe harbor under
§1.263(a)–1(f) to amounts paid for the scanners,
rather than treat these amounts as costs of materials
and supplies under this section. In accordance with
§1.263(a)–1(f)(3)(iv), G may deduct the amounts
paid for all 50 scanners under §1.162–1 in the taxable
year the amounts are paid.
Example 9.Unit of property that costs $200 or
less; bulk purchase
. H provides consulting services
to its customers. In Year 1, H pays $500 to purchase
one box of 10 toner cartridges to use as needed for
H’s printers. Assume each toner cartridge is a unit
of property under §1.263(a)–3(e). In Year 1, H’s em-
ployees place 8 of the toner cartridges in printers in
H’s office, and store the remaining 2 cartridges for use
in a later taxable year. The toner cartridges are mate-
rials and supplies under paragraph (c)(1)(iv) of this
section because even though purchased in one box
costing more than $200, the allocable cost of each
unit of property equals $50. Therefore, under para-
graph (a)(1) of this section, the $400 paid by H for 8 of
the cartridges is deductible in Year 1, the taxable year
in which H first uses each of those cartridges. The
amounts paid by H for each of the remaining 2 car-
tridges ($50 each) are deductible in the taxable year
in which each cartridge is first used in H’s business.
Example 10.Materials and supplies used in
improvements; coordination with §1.263(a)–3
.J
owns various machines that are used in its business.
Assume that each machine is a unit of property under
§1.263(a)–3(e). In Year 1, J purchases a supply of
spare parts for its machines. J acquired the parts
to use in the repair or maintenance of the machines
under §1.162–4 or in the improvement of the ma-
chines under §1.263(a)–3. The spare parts are not
rotable or temporary spare parts under paragraph
(c)(2) of this section. In Year 2, J uses all of these
spare parts in an activity that improves a machine
under §1.263(a)–3. Under paragraph (c)(1)(i) of this
section, the spare parts purchased by J in Year 1 are
materials and supplies. Under paragraph (a)(1) of
this section, the amounts paid for the spare parts are
otherwise deductible as materials and supplies in
Year 2, the taxable year in which J uses those parts.
However, because these materials and supplies are
used to improve J’s machine, J is required to capi-
talize the amounts paid for those spare parts under
§1.263(a)–3.
Example 11.Cost of producing materials and
supplies; coordination with section 263A
.Kisaman-
ufacturer that produces liquid waste as part of its op-
erations. K determines that its current liquid waste
disposal process is inadequate. To remedy the prob-
lem, in Year 1, K constructs a leaching pit to provide a
draining area for the liquid waste. Assume the leach-
ing pit is a unit of property under §1.263(a)–3(e) and
hasaneconomicusefullifeof12monthsorless,start-
ing on the date that K begins to use the leaching pit
as a draining area. At the end of this period, K’s fac-
tory will be connected to the local sewer system. In
Year 2, K starts using the leaching pit in its operations.
The amounts paid to construct the leaching pit (in-
cluding the direct and allocable indirect costs of prop-
erty produced under section 263A) are amounts paid
for a material or supply under paragraph (c)(1)(iii) of
this section. However, the amounts paid to construct
the leaching pit may be subject to capitalization under
section 263A if these amounts comprise the direct or
allocable indirect costs of property produced by K.
Example 12.Costs of acquiring materials and
supplies for production of property; coordination
with section 263A
. In Year 1, L purchases jigs, dies,
molds, and patterns for use in the manufacture of L’s
products. Assume each jig, die, mold, and pattern
is a unit of property under §1.263(a)–3(e). The eco-
nomic useful life of each jig, die, mold, and pattern
is 12 months or less, beginning when each item is
used in the manufacturing process. The jigs, dies,
molds, and patterns are not components acquired to
maintain, repair, or improve any of L’s equipment
under paragraph (c)(1)(i) of this section. L begins
using the jigs, dies, molds and patterns in Year 2 to
manufacture its products. These items are materi-
als and supplies under paragraph (c)(1)(iii) of this
section. Under paragraph (a)(1) of this section, the
amounts paid for the items are otherwise deductible
in Year 2, the taxable year in which L first uses those
items. However, the amounts paid for these materials
and supplies may be subject to capitalization under
section 263A if these amounts comprise the direct or
allocable indirect costs of property produced by L.
Example 13.Election to capitalize and depreci-
ate
. M is in the mining business. M acquires cer-
tain temporary spare parts, which it keeps on hand
to avoid operational time loss in the event it must
make temporary repairs to a unit of property that is
subject to depreciation. These parts are not used to
improve property under §1.263(a)–3(d). These tem-
porary spare parts are used until a new or repaired
part can be installed and then are removed and stored
for later temporary installation. M does not use the
optional method of accounting for rotable and tem-
porary spare parts in paragraph (e) of this section for
any of its rotable or temporary spare parts. The tem-
porary spare parts are materials and supplies under
paragraph (c)(1)(i) of this section. Under paragraphs
(a)(1) and (a)(3) of this section, the amounts paid for
the temporary spare parts are deductible in the tax-
able year in which they are disposed of by M. How-
ever, because it is unlikely that the temporary spare
2013–43 I.R.B.351October 21, 2013

parts will be disposed of in the near future, M would
prefer to treat the amounts paid for the spare parts as
capital expenditures subject to depreciation. M may
elect under paragraph (d) of this section to treat the
cost of each temporary spare part as a capital expen-
diture and as an asset subject to an allowance for de-
preciation. M makes this election by capitalizing the
amounts paid for each spare part in the taxable year
that M acquires the spare parts and by beginning to
recover the costs of each part on its timely filed Fed-
eral tax return for the taxable year in which the part is
placed in service for purposes of determining depre-
ciation under the applicable provisions of the Inter-
nal Revenue Code and the Treasury Regulations. See
§1.263(a)–2(g) for the treatment of capital expendi-
tures.
Example 14.Election to apply de minimis safe
harbor.
(i) N provides consulting services to its cus-
tomers. In Year 1, N pays amounts to purchase 50
laptop computers. Each laptop computer is a unit of
property under §1.263(a)–3(e), costs $400, and has an
economic useful life of more than 12 months. Also in
Year 1, N purchases 50 office chairs to be used by its
employees. Each office chair is a unit of property that
costs $100. N has an applicable financial statement
(as defined in §1.263(a)–1(f)(4)) and N has a written
accountingpolicyatthebeginningYear1toexpense
amounts paid for units of property costing $500 or
less. N treats amounts paid for property costing $500
or less as an expense on its applicable financial state-
ment in Year 1.
(ii) The laptop computers are not materials or
supplies under paragraph (c) of this section. There-
fore, the amounts N pays for the computers must
generally be capitalized under §1.263(a)–2(d) as
amounts paid for the acquisition of tangible property.
The office chairs are materials and supplies under
paragraph (c)(1)(iv) of this section. Thus, under
paragraph (a)(1) of this section, the amounts paid
for the office chairs are deductible in the taxable
year in which they are first used in N’s business.
However, under paragraph (f) of this section, if N
properly elects to apply the
de minimissafe harbor
under §1.263(a)–1(f) to amounts paid in Year 1,
then N must apply the
de minimissafe harbor under
§1.263(a)–1(f) to amounts paid for the computers and
the office chairs, rather than treat the office chairs as
the costs of materials and supplies under §1.162–3.
Under the
de minimissafe harbor, N may not cap-
italize the amounts paid for the computers under
§1.263(a)–2 nor treat the office chairs as materials
and supplies under §1.162–3. Instead, in accordance
with §1.263(a)–1(f)(3)(iv), under §1.162–1, N may
deduct the amounts paid for the computers and the
office chairs in the taxable year paid.

Par. 15. Section 1.167(a)–8T is re-
moved.
Par.16.Section1.168(i)–7isaddedto
read as follows:
§1.168(i)–7 Accounting for MACRS
property.
(a)In general. A taxpayer may ac-
count for MACRS property (as defined in
§1.168(b)–1(a)(2)) by treating each indi-
vidual asset as an account (a “single as-
set account” or an “item account”) or by
combining two or more assets in a single
account (a “multiple asset account” or a
“pool”). A taxpayer may establish as many
accounts for MACRS property as the tax-
payer wants. This section does not apply to
assets included in general asset accounts.
For rules applicable to general asset ac-
counts, see §1.168(i)–1, §1.168(i)–1T, or
Prop. Reg. §1.168(i)–1 (September 19,
2013), as applicable.
(b)Required use of single asset ac-
counts. A taxpayer must account for an as-
set in a single asset account if the taxpayer
uses the asset both in a trade or business
(or for the production of income) and in a
personal activity, or if the taxpayer places
in service and disposes of the asset during
the same taxable year. Also, if general
asset account treatment for an asset ter-
minates under §1.168(i)–1T(c)(1)(ii)(A),
(e)(3)(iii), (e)(3)(vii), (g), or (h)(2) or
Prop. Reg. §1.168(i)–1(c)(1)(ii)(A),
(e)(3)(iii), (e)(3)(vii), (g), or (h)(2)
(September 19, 2013),as applicable, the
taxpayer must account for the asset in
a single asset account beginning in the
taxable year in which the general asset
account treatment for the asset termi-
nates. If a taxpayer accounts for an asset
in a multiple asset account or a pool and
the taxpayer disposes of the asset, the
taxpayer must account for the asset in
a single asset account beginning in the
taxable year in which the disposition oc-
curs. See §1.168(i)–8T(g)(2)(i) or Prop.
Reg. §1.168(i)–8(h)(2)(i) (September 19,
2013), as applicable. If a taxpayer dis-
poses of a component of a larger asset
and the unadjusted depreciable basis of
the disposed of component is included in
the unadjusted depreciable basis of the
larger asset, the taxpayer must account
for the component in a single asset ac-
count beginning in the taxable year in
which the disposition occurs. See Prop.
Reg. §1.168(i)–8(g)(3)(i) (September 19,
2013).
(c)Establishment of multiple asset ac-
counts or pools—(1)Assets eligible for
multiple asset accounts or pools. Except
as provided in paragraph (b) of this section,
assets that are subject to either the general
depreciation system of section 168(a) or
the alternative depreciation system of sec-
tion 168(g) may be accounted for in one or
more multiple asset accounts or pools.
(2)Grouping assets in multiple asset
accounts or pools—(i)General rules.As-
sets that are eligible to be grouped into a
single multiple asset account or pool may
be divided into more than one multiple as-
set account or pool. Each multiple asset
October 21, 20133542013–43 I.R.B.

account or pool must include only assets
that—
(A) Have the same applicable deprecia-
tion method;
(B) Have the same applicable recovery
period;
(C) Have the same applicable conven-
tion; and
(D) Are placed in service by the tax-
payer in the same taxable year.
(ii)Special rules.Inadditiontothegen-
eral rules in paragraph (c)(2)(i) of this sec-
tion, the following rules apply when estab-
lishing multiple asset accounts or pools—
(A) Assets subject to the mid-quarter
convention may only be grouped into a
multiple asset account or pool with assets

§1.263(a)–0T [Removed]
Par. 19. Section 1.263(a)–0T is re-
moved.
Par. 20. Section 1.263(a)–1 is revised
to read as follows:
§1.263(a)–1 Capital expenditures; in
general.
(a)General rule for capital expendi-
tures. Except as provided in chapter 1 of
the Internal Revenue Code, no deduction
is allowed for—
(1) Any amount paid for new buildings
or for permanent improvements or better-
ments made to increase the value of any
property or estate; or
(2) Any amount paid in restoring prop-
erty or in making good the exhaustion
thereof for which an allowance is or has
been made.
(b)Coordination with other provisions
of the Internal Revenue Code. Nothing in
this section changes the treatment of any
amount that is specifically provided for un-
der any provision of the Internal Revenue
Code or the Treasury Regulations other
than section 162(a) or section 212 and the
regulations under those sections. For ex-
ample, see section 263A, which requires
taxpayers to capitalize the direct and allo-
cable indirect costs to property produced
by the taxpayer and property acquired for
resale. See also section 195 requiring tax-
payers to capitalize certain costs as start-up
expenditures.
(c)Definitions. For purposes of this
section, the following definitions apply:
(1)Amount paid. In the case of a tax-
payer using an accrual method of account-
ing, the termsamount paidandpayment
mean a liability incurred (within the mean-
ing of §1.446–1(c)(1)(ii)). A liability may
not be taken into account under this section
prior to the taxable year during which the
liability is incurred.
(2)Producemeans construct, build, in-
stall, manufacture, develop, create, raise,
or grow. This definition is intended to have
the same meaning as the definition used
for purposes of section 263A(g)(1) and
§1.263A–2(a)(1)(i), except that improve-
ments are excluded from the definition in
this paragraph (c)(2) and are separately de-
fined and addressed in §1.263(a)–3.
(d)Examples of capital expenditures.
The following amounts paid are examples
of capital expenditures:
(1) An amount paid to acquire or pro-
duce a unit of real or personal tangible
property. See §1.263(a)–2.
(2)Anamountpaidtoimproveaunit
of real or personal tangible property. See
§1.263(a)–3.
(3) An amount paid to acquire or create
intangibles. See §1.263(a)–4.
(4)Anamountpaidorincurredtofacil-
itate an acquisition of a trade or business,
a change in capital structure of a business
entity, and certain other transactions. See
§1.263(a)–5.
(5) An amount paid to acquire or create
interests in land, such as easements, life es-
tates, mineral interests, timber rights, zon-
ing variances, or other interests in land.
(6) An amount assessed and paid un-
der an agreement between bondholders or
shareholders of a corporation to be used in
a reorganization of the corporation or vol-
untary contributions by shareholders to the
capital of the corporation for any corporate
purpose. See section 118 and §1.118–1.
(7)Anamountpaidbyaholdingcom-
pany to carry out a guaranty of dividends
at a specified rate on the stock of a sub-
sidiary corporation for the purpose of se-
curing new capital for the subsidiary and
increasing the value of its stockholdings in
the subsidiary. This amount must be added
to the cost of the stock in the subsidiary.
(e)Amounts paid to sell property—(1)
In general. Commissions and other trans-
action costs paid to facilitate the sale
of property are not currently deductible
under section 162 or 212. Instead, the
amounts are capitalizedcosts that reduce
the amount realizedin the taxable year
in which the sale occurs or are taken into
account in the taxable year in which the
sale is abandoned if a deduction is per-
missible. These amounts are not added to
the basis of the property sold or treated
as an intangible asset under §1.263(a)–4.
See §1.263(a)–5(g) for the treatment of
amounts paid to facilitate the disposition
of assets that constitute a trade or business.
2013–43 I.R.B.357October 21, 2013

(2)Dealer in property. In the case of a
dealer in property, amounts paid to facili-
tate the sale of such property are treated as
ordinary and necessary business expenses.
(3)Examples. The following examples,
which assume the sale is not an installment
sale under section 453, illustrate the rules
of this paragraph (e):
Example 1.Sales costs of real property.Aowns
a parcel of real estate. A sells the real estate and pays
legal fees, recording fees, and sales commissions to
facilitate the sale. A must capitalize the fees and com-
missions and, in the taxable year of the sale, must re-
duce the amount realized from the sale of the real es-
tate by the fees and commissions.
Example 2.Sales costs of dealers.Assume the
same facts as in
Example 1, except that A is a dealer
in real estate. The commissions and fees paid to fa-
cilitate the sale of the real estate may be deducted as
ordinary and necessary business expenses under sec-
tion 162.
Example 3.Sales costs of personal property used
in a trade or business
. B owns a truck for use in
B’s trade or business. B decides to sell the truck on
November 15, Year 1. B pays for an appraisal to
determine a reasonable asking price. On February
15,Year2,BsellsthetrucktoC.InYear1,Bmust
capitalize the amount paid to appraise the truck, and
in Year 2, must reduce the amount realized from the
sale of the truck by the amount paid for the appraisal.
Example 4.Costs of abandoned sale of personal
property used in a trade or business.
Assume the
same facts as in
Example 3, except that, instead of
selling the truck on February 15, Year 2, B decides on
that date not to sell the truck and takes the truck off
the market. In Year 1, B must capitalize the amount
paid to appraise the truck. However, B may recognize
the amount paid to appraise the truck as a loss under
section 165 in Year 2, the taxable year when the sale
is abandoned.
Example 5.Sales costs of personal property not
used in a trade or business.
Assume the same facts as
in
Example 3, except that B does not use the truck in
B’s trade or business but instead uses it for personal
purposes. In Year 1, B must capitalize the amount
paid to appraise the truck, and in Year 2, must reduce
the amount realized from the sale of the truck by the
amount paid for the appraisal.
Example 6.Costs of abandoned sale of personal
property not used in a trade or business
. Assume the
same facts as in
Example 5, except that, instead of
selling the truck on February 15, Year 2, B decides on
that date not to sell the truck and takes the truck off
the market. In Year 1, B must capitalize the amount
paid to appraise the truck. Although B abandons the
sale in Year 2, B may not treat the amount paid to
appraise the truck as a loss under section 165 because
the truck was not used in B’s trade or business or in a
transaction entered into for profit.
(f)De minimis safe harbor elec-
tion—(1)In general. Except as otherwise
provided in paragraph (f)(2) of this section,

cable financial statement defined in para-
graph(f)(4)ofthissectioninadditiontoa

quirements of paragraph (f)(4) of this sec-
tion, the taxpayer must meet the require-
ments of paragraph (f)(1)(i) of this section
to qualify to elect thede minimissafe har-
bor under this paragraph (f).

and other additional costs.A taxpayer
electing to apply thede minimissafe har-
bor under paragraph (f)(1) of this section

October 21, 20133582013–43 I.R.B.

the taxpayer electing to apply thede min-
imissafe harbor under paragraph (f)(1)
of this section must include in the cost
of such property all additional costs (for
example, delivery fees,installation ser-
vices, or similar costs) if these additional
costs are included on the same invoice
with the tangible property. For purposes
of this paragraph, if the invoice includes
amounts paid for multiple tangible prop-
erties and such invoice includes additional
invoice costs related to these multiple
properties, then the taxpayer must allocate
the additional invoice costs to each prop-
erty using a reasonable method, and each
property, including allocable labor and
overhead, must meet the requirements of
paragraph (f)(1)(i) or paragraph (f)(1)(ii)
of this section, whichever is applicable.
Reasonable allocation methods include,
but are not limited to specific identifica-
tion, apro rataallocation, or a weighted
average method based on the property’s
relative cost. For purposes of this para-
graph (f)(3)(i), additional costs consist of
the costs of facilitating the acquisition or
production of such tangible property un-
der §1.263(a)–2(f) and the costs for work
performed prior to the date that the tan-
gible property is placed in service under
§1.263(a)–2(d).
(ii)Materials and supplies.Ifatax-
payer elects to apply thede minimissafe
harbor provided under this paragraph (f),
then the taxpayer must also apply thede
minimissafe harbor to amounts paid for
all materials and supplies (as defined un-
der §1.162–3) that meet the requirements
of §1.263(a)–1(f). See paragraph (f)(3)(iv)
of this section for treatment of materials
and supplies under thede minimissafe har-
bor.
(iii)Sale or disposition. Property to
which a taxpayer applies thede minimis
safe harbor contained in this paragraph (f)
is not treated upon sale or other disposition
as a capital asset under section 1221 or
as property used in the trade or business
under section 1231.
(iv)Treatment of de minimis amounts.
An amount paid for property to which a
taxpayer properly applies thede minimis
safe harbor contained in this paragraph (f)
is not treated as a capital expenditure un-
der §1.263(a)–2(d)(1) or §1.263(a)–3(d) or
as a material and supply under §1.162–3,
and may be deducted under §1.162–1 in
the taxable year the amount is paid pro-
vided the amount otherwise constitutes an
ordinary and necessary expense incurred
in carrying on a trade or business.
(v)Coordination with section 263A.
Amounts paid for tangible property de-
scribed in paragraph (f)(1) of this section
may be subject to capitalization under
section 263A if the amounts paid for
tangible property comprise the direct or
allocable indirect costs of other property
produced by the taxpayer or property
acquired for resale. See, for example,
§1.263A–1(e)(3)(ii)(R) requiring taxpay-
ers to capitalize the cost of tools and
equipment allocableto property produced
or property acquired for resale.
(vi)Written accounting procedures for
groups of entities.Ifthetaxpayer’sfi-
nancial results are reported on the applica-
ble financial statement (as defined in para-
graph (f)(4) of this section) for a group
of entities then, for purposes of paragraph
(f)(1)(i)(A) of this section, the group’s ap-
plicable financial statement may be treated
as the applicable financial statement of
the taxpayer, and for purposes of para-
graphs (f)(1)(i)(B) and (f)(1)(i)(C) of this
section, the written accounting procedures
provided for the group and utilized for the
group’s applicable financial statement may
be treated as the written accounting proce-
dures of the taxpayer.
(vii)Combined expensing accounting
procedures. For purposes of paragraphs
(f)(1)(i) and (f)(1)(ii) of this section, if
the taxpayer has, at the beginning of the
taxable year accounting procedures treat-
ing as an expense for non-tax purposes (1)
amounts paid for property costing less than
a specified dollar amount; and (2) amounts
paid for property with an economic use-
ful life (as defined in §1.162–3(c)(4)) of
12 months or less, then a taxpayer elect-
ingtoapplythede minimissafe harbor un-
der this paragraph (f) must apply the provi-
sions of this paragraph (f) to amounts qual-
ifying under either accounting procedure.
(4)Definition of applicable financial
statement. For purposes of this para-
graph (f), the taxpayer’s applicable fi-
nancial statement (AFS) is the taxpayer’s
financial statement listed in paragraphs
(f)(4)(i) through (iii) of this section that
has the highest priority (including within
paragraph (f)(4)(ii) of this section). The
financial statements are, in descending
priority—
(i) A financial statement required to
be filed with the Securities and Exchange
Commission (SEC) (the 10–K or the An-
nual Statement to Shareholders);
(ii) A certified audited financial state-
ment that is accompanied by the report of
an independent certified public accountant
(or in the case of a foreign entity, by the
report of a similarly qualified independent
professional) that is used for—
(A) Credit purposes;
(B) Reporting to shareholders, partners,
or similar persons; or
(C) Any other substantial non-tax pur-
pose; or
(iii) A financial statement (other than
a tax return) required to be provided to
the federal or a state government or any
federal or state agency (other than the SEC
or the Internal Revenue Service).
(5)Time and manner of election.A
taxpayer that makes the election under this
paragraph (f) must make the election for
all amounts paid during the taxable year
for property described in paragraph (f)(1)
of this section and meeting the require-
ments of paragraph (f)(1)(i) or paragraph
(f)(1)(ii) of this section, as applicable. A
taxpayer makes the election by attaching
a statement to the taxpayer’s timely filed
original Federal tax return (including ex-
tensions) for the taxable year in which
these amounts are paid. See §§301.9100–1
through 301.9100–3 of this chapter for the
provisions governing extensions of time to
make regulatory elections. The statement
must be titled “Section 1.263(a)–1(f)de
minimissafe harbor election” and include
the taxpayer’s name, address, taxpayer
identification number, and a statement
that the taxpayer is making thede minimis
safe harbor election under §1.263(a)–1(f).
In the case of a consolidated group fil-
ing a consolidated income tax return, the
election is made for each member of the
consolidated group by the common parent,
and the statement must also include the
names and taxpayer identification num-
bers of each member for which the election
is made. In the case of an S corporation or
a partnership, the election is made by the S
corporation or the partnership and not by
the shareholders or partners. An election
may not be made through the filing of
an application forchange in accounting
method or, before obtaining the Commis-
sioner’s consent to make a late election,
by filing an amended Federal tax return.
2013–43 I.R.B.359October 21, 2013

A taxpayer may not revoke an election
made under this paragraph (f). The man-
ner of electing thede minimissafe harbor
under this paragraph (f) may be modified
through guidance of general applicability
(see §§601.601(d)(2) and 601.602 of this
chapter).
(6)Anti-abuse rule. If a taxpayer acts
to manipulate transactions with the intent
to achieve a tax benefit or to avoid the
application of the limitations provided un-
der paragraphs (f)(1)(i)(B)(1), (f)(1)(i)(D),
(f)(1)(ii)(B)(1), and (f)(1)(ii)(D) of this
section, appropriate adjustments will be
made to carry out the purposes of this sec-
tion. For example, a taxpayer is deemed
to act to manipulate transactions with an
intent to avoid the purposes and require-
ments of this section if—
(i) The taxpayer applies thede minimis
safe harbor to amounts substantiated with
invoices created to componentize property
that is generally acquired or produced by
the taxpayer (or other taxpayers in the
same or similar trade or business) as a
single unit of tangible property; and
(ii) This property, if treated as
a single unit, would exceed any of
the limitations provided under para-
graphs (f)(1)(i)(B)(1),(f)(1)(i)(D),
(f)(1)(ii)(B)(1), and (f)(1)(ii)(D) of this
section, as applicable.
(7)Examples. The following examples
illustrate the application of this paragraph
(f). Unless otherwise provided, assume
that section 263A does not apply to the
amounts described.
Example 1.De minimis safe harbor; taxpayer
without AFS
. In Year 1, A purchases 10 printers at
$250 each for a total cost of $2,500 as indicated by the
invoice. Assume that each printer is a unit of prop-
erty under §1.263(a)–3(e). A does not have an AFS.
A has accounting procedures in place at the beginning
of Year 1 to expense amounts paid for property cost-
ing less than $500, and A treats the amounts paid for
the printers as an expense on its books and records.
The amounts paid for the printers meet the require-
ments for the
de minimissafe harbor under paragraph
(f)(1)(ii) of this section. If A elects to apply the
de
minimis
safe harbor under this paragraph (f) in Year
1, A may not capitalize the amounts paid for the 10
printers or any other amounts meeting the criteria for
the
de minimissafe harbor under paragraph (f)(1). In-
stead, in accordance with paragraph (f)(3)(iv) of this
section, A may deduct these amounts under §1.162–1
in the taxable year the amounts are paid provided the
amounts otherwise constitute deductible ordinary and
necessary expenses incurred in carrying on a trade or
business.
Example 2.De minimis safe harbor; taxpayer
without AFS
. In Year 1, B purchases 10 computers
at $600 each for a total cost of $6,000 as indicated by
the invoice. Assume that each computer is a unit of
property under §1.263(a)–3(e). B does not have an
AFS. B has accounting procedures in place at the be-
ginning of Year 1 to expense amounts paid for prop-
erty costing less than $1,000 and B treats the amounts
paid for the computers as an expense on its books
and records. The amounts paid for the printers do
not meet the requirements for the
de minimissafe har-
bor under paragraph (f)(1)(ii) of this section because
the amount paid for the property exceeds $500 per
invoice (or per item as substantiated by the invoice).
B may not apply the
de minimissafe harbor election
to the amounts paid for the 10 computers under para-
graph (f)(1) of this section.
Example 3.De minimis safe harbor; taxpayer
with AFS
. C is a member of a consolidated group
for Federal income tax purposes. C’s financial re-
sults are reported on the consolidatedapplicable fi-
nancial statements for the affiliated group. C’s affili-
ated group has a written accounting policy at the be-
ginningofYear1,whichisfollowedbyC,toexpense
amounts paid for property costing $5,000 or less. In
Year 1, C pays $6,250,000 to purchase 1,250 com-
puters at $5,000 each. C receives an invoice from its
supplier indicating the total amount due ($6,250,000)
and the price per item ($5,000). Assume that each
computer is a unit of property under §1.263(a)–3(e).
The amounts paid for the computers meet the require-
ments for the
de minimissafe harbor under paragraph
(f)(1)(i)ofthissection. IfCelectstoapplythe
de
minimis
safe harbor under this paragraph (f) for Year
1, C may not capitalize the amounts paid for the 1,250
computers or any other amounts meeting the criteria
for the
de minimissafe harbor under paragraph (f)(1)
of this section. Instead, in accordance with paragraph
(f)(3)(iv) of this section, C may deduct these amounts
under §1.162–1 in the taxable year the amounts are
paid provided the amounts otherwise constitute de-
ductible ordinary and necessary expenses incurred in
carrying on a trade or business.
Example 4.De minimis safe harbor; taxpayer
with AFS
. D is a member of a consolidated group
for Federal income tax purposes. D’s financial re-
sults are reported on the consolidatedapplicable fi-
nancial statements for the affiliated group. D’s affili-
ated group has a written accounting policy at the be-
ginning of Year 1, which is followed by D, to expense
amounts paid for property costing less than $15,000.
In Year 1, D pays $4,800,000 to purchase 800 el-
liptical machines at $6,000 each. D receives an in-
voice from its supplier indicating the total amount due
($4,800,000) and the price per item ($6,000). Assume
that each elliptical machine is a unit of property un-
der §1.263(a)–3(e). D may not apply the
de minimis
safe harbor election to the amounts paid for the 800
elliptical machines under paragraph (f)(1) of this sec-
tion because the amount paid for the property exceeds
$5,000 per invoice (or per item as substantiated by the
invoice).
Example 5.De minimis safe harbor; additional
invoice costs
. E is a member of a consolidated group
for Federal income tax purposes. E’s financial re-
sults are reported on the consolidatedapplicable fi-
nancial statements for the affiliated group. E’s af-
filiated group has a written accounting policy at the
beginningofYear1,whichisfollowedbyE,toex-
pense amounts paid for property costing less than
$5,000. In Year 1, E pays $45,000 for the purchase
and installation of wireless routers in each of its 10
office locations. Assume that each wireless router
is a unit of property under §1.263(a)–3(e). E re-
ceives an invoice from its supplier indicating the total
amount due ($45,000), including the material price
per item ($2,500), and total delivery and installation
($20,000). E allocates the additional invoice costs to
the materials on a
pro ratabasis, bringing the cost of
each router to $4,500 ($2,500 materials + $2,000 la-
bor and overhead). The amounts paid for each router,
including the allocable additional invoice costs, meet
the requirements for the
de minimissafe harbor under
paragraph (f)(1)(i) of this section. If E elects to ap-
ply the
de minimissafe harbor under this paragraph
(f) for Year 1, E may not capitalize the amounts paid
for the 10 routers (including the additional invoice
costs) or any other amounts meeting the criteria for
the
de minimissafe harbor under paragraph (f)(1) of
this section. Instead, in accordance with paragraph
(f)(3)(iv) of this section, E may deduct these amounts
under §1.162–1 in the taxable year the amounts are
paid provided the amounts otherwise constitute de-
ductible ordinary and necessary expenses incurred in
carryingonatradeorbusiness.
Example 6.De minimis safe harbor; non-invoice
additional costs
. F is a corporation that provides
consulting services to its customer. F does not have
an AFS, but F has accounting procedures in place
at the beginning of Year 1 to expense amounts paid
for property costing less than $500. In Year 1, F
pays $600 to an interior designer to shop for, eval-
uate, and make recommendations regarding purchas-
ing new furniture for F’s conference room. As a re-
sult of the interior designer’s recommendations, F ac-
quires a conference table for $500 and 10 chairs for
$300 each. In Year 1, F receives an invoice from the
interior designer for $600 for his services, and F re-
ceives a separate invoice from the furniture supplier
indicating a total amount due of $500 for the table and
$300 for each chair. For Year 1, F treats the amount
paid for the table and each chair as an expense on its
books and records, and F elects to use the
de minimis
safe harbor for amounts paid for tangible property
that qualify under the safe harbor. The amount paid
to the interior designer is a cost of facilitating the ac-
quisition of the table and chairs under §1.263(a)–2(f).
Under paragraph (f)(3)(i) of this section, F is not re-
quired to include in the cost of tangible property the
additional costs of acquiring such property if these
costs are not included in the same invoice as the tan-
gible property. Thus, F is not required to include a
pro
rata
allocation of the amount paid to the interior de-
signer to determine the application of the
de minimis
safe harbor to the table and the chairs. Accordingly,
the amounts paid by F for the table and each chair
meet the requirements for the
de minimissafe harbor
under paragraph (f)(1)(ii) of this section, and F may
not capitalize the amounts paid for the table or each
chair under paragraph (f)(1) of this section. In addi-
tion, F is not required to capitalize the amounts paid to
the interior designer as a cost that facilitates the acqui-
sition of tangible property under §1.263(a)–2(f)(3)(i).
Instead, F may deduct the amounts paid for the ta-
ble, chairs, and interior designer under §1.162–1 in
the taxable year the amounts are paid provided the
amounts otherwise constitute deductible ordinary and
necessary expenses incurred in carrying on a trade or
business.
Example 7.De minimis safe harbor; 12-month
economic useful life
. G operates a restaurant. In Year
October 21, 20133602013–43 I.R.B.

1, G purchases 10 hand-held point-of-service devices
at $300 each for a total cost of $3,000 as indicated by
invoice. G also purchases 3 tablet computers at $500
each for a total cost of $1,500 as indicated by invoice.
Assume each point-of-service device and each tablet
computer has an economic useful life of 12 months or
less, beginning when they are used in G’s business.
Assume that each device and each tablet is a unit of
property under §1.263(a)–3(e). G does not have an
AFS, but G has accounting procedures in place at
the beginning of Year 1 to expense amounts paid for
property costing $300 or less and to expense amounts
paid for property with an economic useful life of 12
months or less. Thus, G expenses the amounts paid
for the hand-held devices on its books and records
because each device costs $300. G also expenses the
amounts paid for the tablet computers on its books
and records because the computers have an economic
useful life of 12 months of less, beginning when they
are used. The amounts paid for the hand-held devices
and the tablet computers meet the requirements for
the
de minimissafe harbor under paragraph (f)(1)(ii)
of this section. If G elects to apply the
de minimis
safe harbor under this paragraph (f) in Year 1, G may
not capitalize the amounts paid for the hand-held de-
vices, the tablet computers, or any other amounts
meeting the criteria for the
de minimissafe harbor un-
der paragraph (f)(1) of this section. Instead, in accor-
dance with paragraph (f)(3)(iv) of this section, G may
deduct the amounts paid for the hand-held devices
and tablet computers under §1.162–1 in the taxable
year the amounts are paid provided the amounts oth-
erwise constitute deductible ordinary and necessary
businessexpensesincurredincarryingonatradeor
business.
Example 8.De minimis safe harbor; limitation.
Assume the facts as in
Example 7, except G purchases
the 3 tablet computers at $600 each for a total cost of
$1,800. The amounts paid for the tablet computers do
not meet the
de minimisrule safe harbor under para-
graphs (f)(1)(ii) and (f)(3)(vii) of this section because
the cost of each computer exceeds $500. Therefore,
the amounts paid for the tablet computers may not be
deducted under the safe harbor.
Example 9.De minimis safe harbor; materi-
als and supplies
. H is a corporation that provides
consulting services to its customers. H has an AFS
and a written accounting policy at the beginning of
the taxable year to expense amounts paid for prop-
erty costing $5,000 or less. In Year 1, H purchases
1,000 computers at $500 each for a total cost of
$500,000. Assume that each computer is a unit of
property under §1.263(a)–3(e) and is not a material
or supply under §1.162–3. In addition, H purchases
200 office chairs at $100 each for a total cost of
$20,000 and 250 customized briefcases at $80 each
for a total cost of $20,000. Assume that each office
chair and each briefcase is a material or supply under
§1.162–3(c)(1). H treats the amounts paid for the
computers, office chairs, and briefcases as expenses
on its AFS. The amounts paid for computers, office
chairs, and briefcases meet the requirements for the
de minimissafe harbor under paragraph (f)(1)(i) of
this section. If H elects to apply the
de minimissafe
harbor under this paragraph (f) in Year 1, H may not
capitalize the amounts paid for the 1,000 computers,
the 200 office chairs, and the 250 briefcases under
paragraph (f)(1) of this section. H may deduct the
amounts paid for the computers, the office chairs,
and the briefcases under §1.162–1 in the taxable year
the amounts are paid provided the amounts other-
wise constitute deductible ordinary and necessary
expenses incurred in carryingonatradeorbusiness.
Example 10.De minimis safe harbor; coordina-
tion with section 263A
. J is a member of a consoli-
dated group for Federal income tax purposes. J’s fi-
nancial results are reported on the consolidated AFS
for the affiliated group. J’s affiliated group has a
written accounting policy at the beginning of Year 1,
which is followed by J, to expense amounts paid for
property costing less than $1,000 or that has an eco-
nomic useful life of 12 months or less. In Year 1,
J acquires jigs, dies, molds, and patterns for use in
the manufacture of J’s products. Assume each jig,
die, mold, and pattern is a unit of property under
§1.263(a)–3(e) and costs less than $1,000. In Year
1, J begins using the jigs, dies, molds and patterns
to manufacture its products. Assume these items are
materials and supplies under §1.162–3(c)(1)(iii), and
J elects to apply the
de minimissafe harbor under
paragraph (f)(1)(i) of this section to amounts quali-
fyingunderthesafeharbor in Year 1. Under para-
graph (f)(3)(v) of this section, the amounts paid for
the jigs, dies, molds, and patterns may be subject to
capitalization under section 263A if the amounts paid
for these tangible properties comprise the direct or al-
locable indirect costs of other propertyproduced by
the taxpayer or property acquired for resale.
Example 11.De minimis safe harbor; anti-abuse
rule
. K is a corporation that provides hauling services
to its customers. In Year 1, K decides to purchase a
truck to use in its business. K does not have an AFS.
K has accounting procedures in place at the begin-
ning of Year 1 to expense amounts paid for property
costing less than $500. K arranges to purchase a used
truck for a total of $1,500. Prior to the acquisition,
K requests the seller to provide multiple invoices for
different parts of the truck. Accordingly, the seller
provides K with four invoices during Year 1—one in-
voice of $500 for the cab, one invoice of $500 for
the engine, one invoice of $300 for the trailer, and
a fourth invoice of $200 for the tires. K treats the
amounts paid under each invoice as an expense on its
books and records. K elects to apply the
de minimis
safe harbor under paragraph (f) of this section in Year
1 and does not capitalize the amounts paid for each
invoice pursuant to the safe harbor. Under paragraph
(f)(6) of this section, K has applied the
de minimis
rule to amounts substantiated with invoices created
to componentize property that is generally acquired
as a single unit of tangible property in the taxpayer’s
type of business, and this property, if treated as sin-
gle unit, would exceed the limitations provided under
the
de minimisrule. Accordingly, K is deemed to ma-
nipulate the transaction to acquire the truck with the
intent to avoid the purposes of this paragraph (f). As
a result, K may not apply the
de minimisrule to these
amounts and is subject to appropriate adjustments.
(g)Accounting method changes.Ex-
cept for paragraph (f) of this section (the
de minimissafe harbor election), a change
to comply with this section is a change in
method of accounting to which the pro-
visions of sections 446 and 481 and the
accompanying regulations apply. A tax-
payer seeking to change to a method of ac-
counting permitted in this section must se-
cure the consent of the Commissioner in
accordance with §1.446–1(e) and follow
the administrative procedures issued under
§1.446–1(e)(3)(ii) for obtaining the Com-
missioner’s consent to change its account-
ing method.
(h)Effective/applicability date—(1)
In general. Except for paragraph (f) of
this section, this section generally applies
to taxable years beginning on or after
January 1, 2014. Paragraph (f) of this
section applies to amounts paid in taxable
years beginning on or after January 1,
2014. Except as provided in paragraph
(h)(1) and paragraph (h)(2) of this section,
§1.263(a)–1 as contained in 26 CFR part 1
edition revised as of April 1, 2011, applies
to taxable years beginning before January
1, 2014.
(2)Early application of this sec-
tion—(i)In general. Except for paragraph
(f) of this section, a taxpayer may choose
to apply this section to taxable years be-
ginning on or after January 1, 2012. A
taxpayer may choose to apply paragraph
(f) of this section to amounts paid in tax-
able years beginning on or after January
1, 2012.
(ii)Transition rule for de minimis safe
harbor election on 2012 or 2013 returns.
If under paragraph (h)(2)(i) of this section,
a taxpayer chooses to make the election
to apply thede minimissafe harbor under
paragraph (f) of this section for amounts
paid in its taxable year beginning on or af-
ter January 1, 2012, and ending on or be-
fore September 19, 2013 (applicable tax-
able year), and the taxpayer did not make
the election specifiedin paragraph (f)(5) of
this section on its timely filed original Fed-
eral tax return for the applicable taxable
year, the taxpayer must make the election
specified in paragraph (f)(5) of this section
for the applicable taxable year by filing an
amended Federal tax return for the appli-
cable taxable year on or before 180 days
from the due date including extensions of
the taxpayer’s Federal tax return for the ap-
plicable taxable year,notwithstanding that
the taxpayer may not have extended the
due date.
(3)Optional application of TD
9564. A taxpayer may choose to apply
§1.263(a)–1T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2012, and before January 1, 2014.
2013–43 I.R.B.361October 21, 2013

§1.263(a)–1T [Removed]
Par. 21. Section 1.263(a)–1T is re-
moved.
Par. 22. Section 1.263(a)–2 is revised
to read as follows:
§1.263(a)–2 Amounts paid to acquire or
produce tangible property.
(a)Overview. This section provides
rules for applying section 263(a) to
amounts paid to acquire or produce a unit
of real or personal property. Paragraph (b)
of this section contains definitions. Para-
graph (c) of this section contains the rules
for coordinating this section with other
provisions of the Internal Revenue Code
(Code). Paragraph (d) of this section pro-
vides the general requirement to capitalize
amounts paid to acquire or produce a unit
of real or personal property. Paragraph (e)
of this section provides the requirement
to capitalize amounts paid to defend or
perfect title to real or personal property.
Paragraph (f) of this section provides the
rules for determining the extent to which
taxpayers must capitalize transaction costs
related to the acquisition of tangible prop-
erty. Paragraphs (g) and (h) of this section
address the treatment and recovery of cap-
ital expenditures. Paragraph (i) of this
section provides for changes in methods
of accounting to comply with this section,
and paragraph (j) of this section provides
the effective and applicability dates for the
rules under this section.
(b)Definitions.For purposes of this
section, the following definitions apply:
(1)Amount paid. In the case of a tax-
payer using an accrual method of account-
ing, the termsamount paidandpayment
mean a liability incurred (within the mean-
ing of §1.446–1(c)(1)(ii)). A liability may
not be taken into account under this section
prior to the taxable year during which the
liability is incurred.
(2)Personal propertymeans tangible
personal property as defined in §1.48–1(c).
(3)Real propertymeans land and im-
provements thereto, such as buildings or
other inherently permanent structures (in-
cluding items that are structural compo-
nents of the buildings or structures) that are
not personal property as defined in para-
graph (b)(2) of this section. Any property
that constitutes other tangible property un-
der §1.48–1(d) is treated as real property
for purposes of this section. Local law
is not controlling in determining whether
property is real property for purposes of
this section.
(4)Producemeans construct, build, in-
stall, manufacture, develop, create, raise,
or grow. This definition is intended to have
the same meaning as the definition used
for purposes of section 263A(g)(1) and
§1.263A–2(a)(1)(i), except that improve-
ments are excluded from the definition in
this paragraph (b)(4) and are separately de-
fined and addressed in §1.263(a)–3.
(c)Coordination with other provisions
of the Code—(1)In general. Nothing in
this section changes the treatment of any
amount that is specifically provided for un-
der any provision of the Code or the Trea-
sury Regulations other than section 162(a)
or section 212 and the regulations under
those sections. For example, see section
263A requiring taxpayers to capitalize the
direct and allocable indirect costs of prop-
erty produced by the taxpayer and prop-
erty acquired for resale. See also section
195 requiring taxpayers to capitalize cer-
tain costs as start-up expenditures.
(2)Materials and supplies. Nothing
in this section changes the treatment of
amounts paid to acquire or produce prop-
erty that is properly treated as materials
and supplies under §1.162–3.
(d)Acquired or produced tangible
property—(1)Requirement to capitalize.
Except as provided in §1.162–3 (relat-
ing to materials and supplies) and in
§1.263(a)–1(f) (providing ade minimis
safe harbor election), a taxpayer must cap-
italize amounts paid to acquire or produce
a unit of real or personal property (as de-
termined under §1.263(a)–3(e)), including
leasehold improvements, land and land
improvements, buildings, machinery and
equipment, and furniture and fixtures. See
§1.263(a)–3(f) for the rules for determin-
ing whether amounts are for leasehold
improvements. Amounts paid to acquire
or produce a unit of real or personal prop-
erty include the invoice price, transaction
costs as determined under paragraph (f) of
this section, and costs for work performed
prior to the date that the unit of property is
placed in service by the taxpayer (without
regard to any applicable convention under
section 168(d)). A taxpayer also must
capitalize amounts paid to acquire real or
personal property for resale.
(2)Examples.The following exam-
ples illustrate the rules of this paragraph
(d). Unless otherwise provided, assume
that the taxpayer does not elect thede min-
imissafe harbor under §1.263(a)–1(f) and
that the property isnot acquired for resale
under section 263A.
Example 1.Acquisition of personal property.A
purchases new cash registers for use in its retail store
located in leased space in a shopping mall. Assume
each cash register is a unit of property as determined
under §1.263(a)–3(e) and is not a material or supply
under §1.162–3. A must capitalize under paragraph
(d)(1) of this section the amount paid to acquire each
cash register.
Example 2.Acquisition of personal property that
is a material or supply; coordination with §1.162–3
.
B operates a fleet of aircraft. In Year 1, B acquires
a stock of component parts, which it intends to use
to maintain and repair its aircraft. Assume that
each component part is a material or supply under
§1.162–3(c)(1) and B does not make elections under
§1.162–3(d) to treat the materials and supplies as
capital expenditures. In Year 2, B uses the component
parts in the repair and maintenance of its aircraft.
Because the parts are materials and supplies under
§1.162–3, B is not required to capitalize the amounts
paid for the parts under paragraph (d)(1) of this
section. Rather, to determine the treatment of these
amounts, B must apply the rules under §1.162–3,
governing the treatment of materials and supplies.
Example 3.Acquisition of unit of personal
property; coordination with §1.162–3
. C operates
a rental business that rents out a variety of small
individual items to customers (rental items). C
maintains a supply of rental items on hand to re-
place worn or damaged items. C purchases a large
quantity of rental items to be used in its business.
Assume that each of these rental items is a unit of
property under §1.263(a)–3(e). Also assume that a
portion of the rental items are materials and supplies
under §1.162–3(c)(1). Under paragraph (d)(1) of
this section, C must capitalize the amounts paid for
the rental items that are not materials and supplies
under §1.162–3(c)(1). However, C must apply the
rules in §1.162–3 to determine the treatment of the
rental items that are materials and supplies under
§1.162–3(c)(1).
Example 4.Acquisition or production cost.D
purchases and produces jigs, dies, molds, and patterns
for use in the manufacture of D’s products. Assume
that each of these items is a unit of property as deter-
mined under §1.263(a)–3(e) and is not a material and
supply under §1.162–3(c)(1). D is required to capital-
ize under paragraph (d)(1) of this section the amounts
paid to acquire and produce the jigs, dies, molds, and
patterns.
Example 5.Acquisition of land.F purchases a
parcel of undeveloped real estate. F must capitalize
under paragraph (d)(1) of this section the amount paid
to acquire the real estate. See paragraph (f) of this
section for the treatment of amounts paid to facilitate
the acquisition of real property.
Example 6.Acquisition of building.G purchases
a building. G must capitalize under paragraph (d)(1)
of this section the amount paid to acquire the building.
See paragraph (f) of this section for the treatment of
October 21, 20133622013–43 I.R.B.

amounts paid to facilitate the acquisition of real prop-
erty.
Example 7.Acquisition of property for resale and
production of property for sale; coordination with
section 263A
. H purchases goods for resale and pro-
duces other goods for sale. H must capitalize under
paragraph (d)(1) of this section the amounts paid to
acquire and produce the goods. See section 263A for
the amounts required to be capitalized to the property
produced or to the property acquired for resale.
Example 8.Production of building; coordination
with section 263A
. J constructs a building. J must
capitalize under paragraph (d)(1) of this section the
amount paid to construct the building. See section
263A for the costs required to be capitalized to the
real property produced by J.
Example 9.Acquisition of assets constituting a
trade or business.
K owns tangible and intangible
assets that constitute a trade or business. L purchases
all the assets of K in a taxable transaction. L must
capitalize under paragraph (d)(1) of this section
theamountpaidforthetangibleassetsofK.See
§1.263(a)–4 for the treatment of amounts paid to
acquire or create intangibles and §1.263(a)–5 for the
treatment of amounts paid to facilitate the acquisition
of assets that constitute a trade or business. See
section 1060 for special allocation rules for certain
asset acquisitions.
Example 10.Work performed prior to placing the
property in service
. In Year 1, M purchases a building
for use as a business office. Prior to placing the build-
ing in service, M pays amounts to repair cement steps,
refinish wood floors, patch holes in walls, and paint
the interiors and exteriors of the building. In Year
2, M places the building in service and begins using
the building as its business office. Assume that the
work that M performs does not constitute an improve-
ment to the building or its structural components un-
der §1.263(a)–3. Under §1.263–3(e)(2)(i), the build-
ing and its structural components is a single unit of
property. Under paragraph (d)(1) of this section, the
amounts paid must be capitalized as amounts to ac-
quire the building unit of property because they were
for work performed prior to M’s placing the building
in service.
Example 11.Work performed prior to placing the
property in service
. In January Year 1, N purchases
a new machine for use in an existing production line
of its manufacturing business. Assume that the ma-
chine is a unit of property under §1.263(a)–3(e) and
is not a material or supply under §1.162–3. N pays
amounts to install the machine, and after the machine
is installed, N pays amounts to perform a critical test
on the machine to ensure that it will operate in ac-
cordance with quality standards. On November 1,
Year 1, the critical test is complete, and N places the
machine in service on the production line. N pays
amounts to perform periodic quality control testing
after the machine is placed in service. Under para-
graph (d)(1) of this section, the amounts paid for
the installation and the critical test performed before
the machine is placed in service must be capitalized
by N as amounts to acquire the machine. However,
amounts paid for periodic quality control testing after
N placed the machine in service are not required to be
capitalized as amounts paid to acquire the machine.
(e)Defense or perfection of title to
property—(1)In general.Amounts paid
to defend or perfect title to real or personal
property are amounts paid to acquire or
produce property within the meaning of
this section and must be capitalized.
(2)Examples.The following examples
illustrate the rule of this paragraph (e):
Example 1. Amounts paid to contest condemna-
tion
. X owns real property located in County. County
files an eminent domain complaint condemning a por-
tion of X’s property to use as a roadway. X hires an
attorney to contest the condemnation. The amounts
that X paid to the attorney must be capitalized be-
cause they were to defend X’s title to the property.
Example 2.Amounts paid to invalidate or-
dinance
. Y is in the business of quarrying and
supplying for sale sand and stone in a certain munic-
ipality. Several years after Y establishes its business,
the municipality in which it is located passes an or-
dinance that prohibits the operation of Y’s business.
Y incurs attorney’s fees in a successful prosecution
of a suit to invalidate the municipal ordinance. Y
prosecutes the suit to preserve its business activities
and not to defend Y’s title in the property. Therefore,
the attorney’s fees that Y paid are not required to be
capitalized under paragraph (e)(1) of this section.
Example 3. Amounts paid to challenge building
line
. The board of public works of a municipality es-
tablishes a building line across Z’s business property,
adversely affecting the value of the property. Z in-
curs legal fees in unsuccessfully litigating the estab-
lishment of the building line. The amounts Z paid to
the attorney must be capitalized because they were to
defend Z’s title to the property.
(f)Transaction costs—(1)In general.
Except as provided in §1.263(a)–1(f)(3)(i)
(for purposes of thede minimissafe har-
bor), a taxpayer must capitalize amounts
paid to facilitate the acquisition of real or
personal property. See §1.263(a)–5 for the
treatment of amounts paid to facilitate the
acquisition of assets that constitute a trade
or business. See §1.167(a)–5 for alloca-
tions of facilitative costs between depre-
ciable and non-depreciable property.
(2)Scope of facilitate—(i)In general.
Except as otherwise provided in this sec-
tion, an amount is paid to facilitate the ac-
quisition of real or personal property if the
amount is paid in the process of investigat-
ing or otherwise pursuing the acquisition.
Whether an amount is paid in the process
of investigating or otherwise pursuing the
acquisition is determined based on all of
the facts and circumstances. In determin-
ing whether an amount is paid to facili-
tate an acquisition, the fact that the amount
would (or would not) have been paid but
for the acquisition is relevant but is not de-
terminative. Amounts paid to facilitate an
acquisition include, but are not limited to,
inherently facilitative amounts specified in
paragraph (f)(2)(ii) of this section.
(ii)Inherently facilitative amounts.An
amount is paid in the process of investigat-
ing or otherwise pursuing the acquisition
of real or personal property if the amount
is inherently facilitative. An amount is in-
herently facilitative if the amount is paid
for—
(A) Transporting the property (for ex-
ample, shipping fees and moving costs);
(B) Securing an appraisal or determin-
ing the value or price of property;
(C) Negotiating the terms or structure
of the acquisition and obtaining tax advice
on the acquisition;
(D) Application fees, bidding costs, or
similar expenses;
(E) Preparing and reviewing the docu-
ments that effectuate the acquisition of the
property (for example, preparing the bid,
offer, sales contract, or purchase agree-
ment);
(F) Examining and evaluating the title
of property;
(G) Obtaining regulatory approval of
the acquisition or securing permits related
to the acquisition, including application
fees;
(H) Conveying property between the
parties, including sales and transfer taxes,
and title registration costs;
(I) Finders’ fees or brokers’ commis-
sions, including contingency fees (defined
in paragraph (f)(3)(iii) of this section);
(J) Architectural, geological, survey,
engineering, environmental, or inspection
services pertaining toparticular proper-
ties; or
(K) Services provided by a qualified in-
termediary or other facilitator of an ex-
change under section 1031.
(iii)Special rule for acquisitions of
real property—(A)In general. Except
as provided in paragraph (f)(2)(ii) of this
section (relating to inherently facilitative
amounts), an amount paid by the tax-
payer in the process of investigating or
otherwise pursuing the acquisition of real
property does not facilitate the acquisition
if it relates to activities performed in the
process of determining whether to acquire
real property and which real property to
acquire.
(B)Acquisitions of real and personal
property in a single transaction.An
amount paid by the taxpayer in the process
of investigating or otherwise pursuing the
acquisition of personal property facilitates
the acquisition of such personal property,
2013–43 I.R.B.363October 21, 2013

even if such property is acquired in a single
transaction that also includes the acquisi-
tion of real property subject to the special
rule set out in paragraph (f)(2)(iii)(A) of
this section. A taxpayer may use a rea-
sonable allocation method to determine
which costs facilitate the acquisition of
personal property and which costs relate
to the acquisition of real property and are
subject to the special rule of paragraph
(f)(2)(iii)(A) of this section.
(iv)Employee compensation and over-
head costs—(A)In general. For purposes
of paragraph (f) of this section, amounts
paid for employee compensation (within
the meaning of §1.263(a)–4(e)(4)(ii)) and
overhead are treated as amounts that do not
facilitate the acquisition of real or personal
property. See section 263A, however, for
the treatment of employee compensation
and overhead costs required to be capital-
ized to property produced by the taxpayer
or to property acquired for resale.
(B)Election to capitalize.Atax-
payer may elect to treat amounts paid for
employee compensation or overhead as
amounts that facilitate the acquisition of
property. The election is made separately
for each acquisition and applies to em-
ployee compensation oroverhead,orboth.
For example, a taxpayer may elect to treat
overhead, but not employee compensation,
as amounts that facilitate the acquisition
of property. A taxpayer makes the election
by treating the amounts to which the elec-
tion applies as amounts that facilitate the
acquisition in the taxpayer’s timely filed
original Federal tax return (including ex-
tensions) for the taxable year during which
the amounts are paid. See §§301.9100–1
through 301.9100–3 of this chapter for the
provisions governing extensions of time
to make regulatory elections. In the case
of an S corporation or a partnership, the
election is made by the S corporation or by
the partnership, andnot by the sharehold-
ers or partners. A taxpayer may revoke
an election made under this paragraph
(f)(2)(iv)(B) with respect to each acquisi-
tion only by filing a request for a private
letter ruling and obtaining the Commis-
sioner’s consent to revoke the election.
The Commissioner may grant a request to
revoke this election if the taxpayer acted
reasonably and in good faith and the re-
vocation will not prejudice the interests of
Government. See generally §301.9100–3
of this chapter. The manner of electing
and revoking the election to capitalize
under this paragraph (f)(2)(iv)(B) may
be modified through guidance of general
applicability (see §§606.601(d)(2) and
601.602 of this section). An election may
not be made or revoked through the filing
of an application forchange in accounting
method or, before obtaining the Commis-
sioner’s consent to make the late election
or to revoke the election, by filing an
amended Federal tax return.
(3)Treatment of transaction costs—(i)
In general. Except as provided under
§1.263(a)–1(f)(3)(i) (for purposes of the
de minimissafe harbor), all amounts paid
to facilitate the acquisition of real or per-
sonal property are capital expenditures.
Facilitative amountsallocable to real or
personal property must be included in the
basis of the property acquired.
(ii)Treatment of inherently facilitative
amounts. Inherently facilitative amounts
allocable to real or personal property are
capital expenditures related to such prop-
erty, even if the property is not eventually
acquired. Except for contingency fees as
defined in paragraph (f)(3)(iii) of this sec-
tion, inherently facilitative amounts allo-
cable to real or personal property not ac-
quired may be allocated to those proper-
ties and recovered as appropriate in accor-
dance with the applicable provisions of the
Code and the Treasury Regulations (for ex-
ample, sections 165, 167, or 168). See
paragraph (h) of this section for the recov-
ery of capitalized amounts.
(iii)Contingency Fees. For purposes of
this section, a contingency fee is an amount
paid that is contingent on the successful
closing of the acquisition of real or per-
sonal property. Contingency fees must be
included in the basis of the property ac-
quired and may not be allocated to the
property not acquired.
(4)Examples.The following exam-
ples illustrate the rules of paragraph (f)
of this section. For purposes of these
examples, assume that the taxpayer does
not elect thede minimissafe harbor under
§1.263(a)–1(f):
Example 1. Broker’s fees to facilitate an acqui-
sition
. A decides to purchase a building in which
to relocate its offices and hires a real estate broker
to find a suitable building. A pays fees to the bro-
ker to find property for A to acquire. Under para-
graph (f)(2)(ii)(I) of this section, A must capitalize
the amounts paid to the broker because these costs are
inherently facilitative of the acquisition of real prop-
erty.
Example 2.Inspection and survey costs to facil-
itate an acquisition
. B decides to purchase Build-
ing X and pays amounts to third-party contractors for
a termite inspection and an environmental survey of
Building X. Under paragraph (f)(2)(ii)(J) of this sec-
tion, B must capitalize the amounts paid for the in-
spection and the survey of the building because these
costs are inherently facilitative of the acquisition of
real property.
Example 3.Moving costs to facilitate an acqui-
sition
. C purchases all the assets of D and, in con-
nection with the purchase, hires a transportation com-
pany to move storage tanks from D’s plant to C’s
plant. Under paragraph (f)(2)(ii)(A) of this section,
C must capitalize the amount paid to move the stor-
age tanks from D’s plant to C’s plant because this cost
is inherently facilitative to the acquisition of personal
property.
Example 4.Geological and geophysical costs;
coordination with other provisions
. E is in the busi-
ness of exploring, purchasing, and developing prop-
erties in the United States for the production of oil
and gas. E considers acquiring a particular property
but first incurs costs for the services of an engineering
firm to perform geological and geophysical studies to
determine if the property is suitable for oil or gas pro-
duction. Assume that the amounts that E paid to the
engineering firm constitute geological and geophysi-
cal expenditures under section 167(h). Although the
amounts that E paid for the geological and geophys-
ical services are inherently facilitative to the acqui-
sition of real property under paragraph (f)(2)(ii)(J)
of this section, E is not required to include those
amounts in the basis of the real property acquired.
Rather, under paragraph (c) of this section, E must
capitalize these costs separately and amortize such
costs as required under section 167(h) (addressing the
amortization of geological and geophysical expendi-
tures).
Example 5.Scope of facilitate. F is in the busi-
ness of providing legal services to clients. F is inter-
ested in acquiring a new conference table for its of-
fice. F hires and incurs fees for an interior designer
to shop for, evaluate, and make recommendations to
F regarding which new table to acquire. Under para-
graphs (f)(1) and (2) of this section, F must capitalize
the amounts paid to the interior designer to provide
these services because they are paid in the process of
investigating or otherwise pursuing the acquisition of
personal property.
Example 6.Transaction costs allocable to multi-
ple properties
. G, a retailer, wants to acquire land for
the purpose of building a new distribution facility for
its products. G considers various properties on High-
way X in State Y. G incurs fees for the services of an
architect to advise and evaluate the suitability of the
sites for the type of facility that G intends to construct
on the selected site. G must capitalize the architect
fees as amounts paid to acquire land because these
amounts are inherently facilitative to the acquisition
of land under paragraph (f)(2)(ii)(J) of this section.
Example 7.Transaction costs; coordination with
section 263A
. H, a retailer, wants to acquire land for
the purpose of building a new distribution facility for
its products. H considers various properties on High-
way X in State Y. H incurs fees for the services of
an architect to prepare preliminary floor plans for a
building that H could construct at any of the sites. Un-
der these facts, the architect’s fees are not facilitative
October 21, 20133642013–43 I.R.B.

to the acquisition of land under paragraph (f) of this
section. Therefore, H is not required to capitalize the
architect fees as amounts paid to acquire land. How-
ever, the amounts paid for the architect’s fees may be
subject to capitalization under section 263A if these
amounts comprise the direct or allocable indirect cost
of property produced by H, such as the building.
Example 8.Special rule for acquisitions of real
property
. J owns several retail stores. J decides to
examine the feasibility of opening a new store in City
X. In October, Year 1, J hires and incurs costs for a
development consulting firm to study City X and per-
form market surveys, evaluate zoning and environ-
mental requirements, and make preliminary reports
and recommendations as to areas that J should con-
sider for purposes of locating a new store. In De-
cember, Year 1, J continues to consider whether to
purchase real property in City X and which property
to acquire. J hires, and incurs fees for, an appraiser
to perform appraisals on two different sites to deter-
mine a fair offering price for each site. In March,
Year 2, J decides to acquire one of these two sites
for the location of its new store. At the same time, J
determines not to acquire the other site. Under para-
graph (f)(2)(iii) of this section, J is not required to
capitalize amounts paid to the development consul-
tant in Year 1 because the amounts relate to activities
performed in the process of determining whether to
acquire real property and which real property to ac-
quire, and the amounts are not inherently facilitative
costs under paragraph (f)(2)(ii) of this section. How-
ever, J must capitalize amounts paid to the appraiser
in Year 1 because the appraisal costs are inherently
facilitative costs under paragraph (f)(2)(ii)(B) of this
section. In Year 2, J must include the appraisal costs
allocable to property acquired in the basis of the prop-
erty acquired. In addition, J may recover the appraisal
costs allocable to the property not acquired in accor-
dance with paragraphs (f)(3)(ii) and (h) of this sec-
tion. See, for example, §1.165–2 for losses on the
permanent withdrawal of non-depreciable property.
Example 9.Contingency fee. K owns several
restaurant properties. K decides to open a new restau-
rant in City X. In October, Year 1, K hires a real estate
consultant to identify potential property upon which
K may locate its restaurant, and is obligated to com-
pensate the consultant upon the acquisition of prop-
erty. The real estate consultant identifies three prop-
erties, and K decides to acquire one of those proper-
ties. Upon closing of the acquisition of that property,
K pays the consultant its fee. The amount paid to the
consultant constitutes a contingency fee under para-
graph (f)(3)(iii) of this section because the payment is
contingent on the successful closing of the acquisition
of property. Accordingly, under paragraph (f)(3)(iii)
of this section, K must include the amount paid to the
consultant in the basis of the property acquired. K is
not permitted to allocate the amount paid between the
properties acquired and not acquired.
Example 10.Employee compensation and over-
head
. L, a freight carrier, maintains an acquisition
department whose sole function is to arrange for the
purchase of vehicles and aircraft from manufacturers
or other parties to be used in its freight carrying busi-
ness. As provided in paragraph (f)(2)(iv)(A) of this
section, L is not required to capitalize any portion of
the compensation paid to employees in its acquisi-
tion department or any portion of its overhead allo-
cable to its acquisition department. However, under
paragraph (f)(2)(iv)(B) of this section, L may elect
to capitalize the compensation and/or overhead costs
allocable to the acquisition of a vehicle or aircraft by
treating these amounts as costs that facilitate the ac-
quisition of that property in its timely filed original
Federal tax return for the year the amounts are paid.
(g)Treatment of capital expenditures.
Amounts required to be capitalized un-
der this section are capital expenditures
and must be taken into account through a
charge to capital account or basis, or in the
case of property that is inventory in the
hands of a taxpayer, through inclusion in
inventory costs.
(h)Recovery of capitalized
amounts—(1)In general. Amounts that
are capitalized under this section are
recovered through depreciation, cost of
goods sold, or by an adjustment to basis at
the time the property is placed in service,
sold, used, or otherwise disposed of by
the taxpayer. Cost recovery is determined
by the applicable provisions of the Code
and regulations relating to the use, sale, or
disposition of property.
(2)Examples. The following examples
illustrate the rule of paragraph (h)(1) of
this section. For purposes of these ex-
amples, assume that the taxpayer does not
elect thede minimissafe harbor under sec-
tion §1.263(a)–1(f).
Example 1.Recovery when property placed in
service
. X owns a 10-unit apartment building. The
refrigerator in one of the apartments stops function-
ing, and X purchases a new refrigerator to replace the
old one. X pays for the acquisition, delivery, and in-
stallation of the new refrigerator. Assume that the re-
frigerator is the unit of property, as determined under
§1.263(a)–3(e), and is not a material or supply under
§1.162–3. Under paragraph (d)(1) of this section, X
is required to capitalize the amounts paid for the ac-
quisition, delivery, and installation of the refrigerator.
Under this paragraph (h), the capitalized amounts are
recovered through depreciation, which begins when
the refrigerator is placed in service by X.
Example 2.Recovery when property used in the
production of property
. Y operates a plant where it
manufactures widgets. Y purchases a tractor loader
to move raw materials into and around the plant for
use in the manufacturing process. Assume that the
tractor loader is a unit of property, as determined un-
der §1.263(a)–3(e), and is not a material or supply un-
der §1.162–3. Under paragraph (d)(1) of this section,
Y is required to capitalize the amounts paid to ac-
quire the tractor loader. Under this paragraph (h), the
capitalized amounts are recovered through deprecia-
tion, which begins when Y places the tractor loader in
service. However, because the tractor loader is used
in the production of property, under section 263A
the cost recovery (that is, the depreciation) may also
be capitalized to Y’s property produced, and, conse-
quently, recovered through cost of goods sold. See
§1.263A–1(e)(3)(ii)(I).
(i)Accounting method changes.Un-
less otherwise provided under this section,
a change to comply with this section is a
change in method of accounting to which
the provisions of sections 446 and 481 and
the accompanying regulations apply. A
taxpayer seeking to change to a method of
accounting permitted in this section must
secure the consent of the Commissioner in
accordance with §1.446–1(e) and follow
the administrative procedures issued under
§1.446–1(e)(3)(ii) for obtaining the Com-
missioner’s consent to change its account-
ing method.
(j)Effective/applicability date—(1)In
general. Except for paragraphs (f)(2)(iii),
(f)(2)(iv), and (f)(3)(ii) of this section,
this section generally applies to taxable
years beginning on or after January 1,
2014. Paragraphs (f)(2)(iii), (f)(2)(iv), and
(f)(3)(ii) of this section apply to amounts
paid in taxable years beginning on or after
January 1, 2014. Except as provided in
paragraphs (j)(1) and (j)(2) of this section,
§1.263(a)–2 as contained in 26 CFR part 1
edition revised as of April 1, 2011, applies
to taxable years beginning before January
1, 2014.
(2)Early application of this sec-
tion—(i)In general. Except for para-
graphs (f)(2)(iii), (f)(2)(iv), and (f)(3)(ii)
of this section of this section, a taxpayer
may choose to apply this section to tax-
able years beginning on or after January
1, 2012. A taxpayer may choose to ap-
ply paragraphs (f)(2)(iii), (f)(2)(iv), and
(f)(3)(ii) of this section to amounts paid
in taxable years beginning on or after Jan-
uary 1, 2012.
(ii)Transition rule for election to cap-
italize employee compensation and over-
head costs on 2012 or 2013 returns. If un-
der paragraph (j)(2)(i) of this section, a tax-
payer chooses to make the election to cap-
italize employee compensation and over-
head costs under paragraph (f)(2)(iv)(B) of
this section for amounts paid in its tax-
able year beginning on or after January 1,
2012, and ending on or before September
19, 2013 (applicable taxable year), and the
taxpayer did not make the election speci-
fied in paragraph (f)(2)(iv)(B) of this sec-
tion on its timely filed original Federal tax
return for the applicable taxable year, the
taxpayer must make the election specified
in paragraph (f)(2)(iv)(B) of this section
for the applicable taxable year by filing an
amended Federal tax return for the appli-
2013–43 I.R.B.365October 21, 2013

cable taxable year on or before 180 days
from the due date including extensions of
the taxpayer’s Federaltax return for the ap-
plicable taxable year, notwithstanding that
the taxpayer may not have extended the
due date.
(3)Optional application of TD
9564. Except for §1.263(a)–2T(f)(2)(iii),
(f)(2)(iv), (f)(3)(ii), and (g), a taxpayer
may choose to apply §1.263(a)–2T as
contained in TD 9564 (76 FR 81060)
December 27, 2011, to taxable years be-
ginning on or after January 1, 2012, and
before January 1, 2014. A taxpayer may
choose to apply §1.263(a)–2T(f)(2)(iii),
(f)(2)(iv), (f)(3)(ii) and (g) as contained
in TD 9564 (76 FR 81060) December 27,
2011, to amounts paid in taxable years
beginning on or after January 1, 2012, and
before January 1, 2014.
§1.263(a)–2T [Removed]
Par. 23. Section 1.263(a)–2T is re-
moved.
Par. 24. Section 1.263(a)–3 is revised
to read as follows:
§1.263(a)–3 Amounts paid to improve
tangible property.
(a)Overview. This section provides
rules for applying section 263(a) to
amounts paid to improve tangible prop-
erty. Paragraph (b) of this section provides
definitions. Paragraph (c) of this section
provides rules for coordinating this sec-
tion with other provisions of the Internal
Revenue Code (Code). Paragraph (d) of
this section provides the requirement to
capitalize amounts paid to improve tangi-
ble property and provides the general rules
for determining whether a unit of property
is improved. Paragraph (e) of this section
provides the rules for determining the ap-
propriate unit of property. Paragraph (f)
of this section provides rules for leasehold
improvements. Paragraph (g) of this sec-
tion provides special rules for determining
improvement costs in particular contexts,
including indirect costs incurred during an
improvement, removal costs, aggregation
of related costs, and regulatory compli-
ance costs. Paragraph (h) of this section
provides a safe harbor for small taxpay-
ers. Paragraph (i) provides a safe harbor
for routine maintenance costs. Paragraph
(j) of this section provides rules for de-
termining whether amounts are paid for
betterments to the unit of property. Para-
graph (k) of this section provides rules for
determining whether amounts are paid to
restore the unit of property. Paragraph (l)
of this section provides rules for amounts
paid to adapt the unit of property to a new
or different use. Paragraph (m) of this
section provides an optional regulatory
accounting method. Paragraph (n) of this
section provides an election to capitalize
repair and maintenance costs consistent
with books and records. Paragraphs (o)
and (p) of this section provide for the treat-
ment and recovery of amounts capitalized
under this section. Paragraphs (q) and
(r) of this section provide for accounting
method changes and state the effective/ap-
plicability date for the rules in this section.
(b)Definitions.For purposes of this
section, the following definitions apply:
(1)Amount paid. In the case of a tax-
payer using an accrual method of account-
ing, the termsamounts paidandpayment
mean a liability incurred (within the mean-
ing of §1.446–1(c)(1)(ii)). A liability may
not be taken into account under this section
prior to the taxable year during which the
liability is incurred.
(2)Personal propertymeans tangible
personal property as defined in §1.48–1(c).
(3)Real propertymeans land and im-
provements thereto, such as buildings or
other inherently permanent structures (in-
cluding items that are structural compo-
nents of the buildings or structures) that are
not personal property as defined in para-
graph (b)(2) of this section. Any property
that constitutes other tangible property un-
der §1.48–1(d) is also treated as real prop-
erty for purposes of this section. Local law
is not controlling in determining whether
property is real property for purposes of
this section.
(4)Ownermeans the taxpayer that has
the benefits and burdens of ownership of
the unit of property for Federal income tax
purposes.
(c)Coordination with other provisions
of the Code—(1)In general. Nothing in
this section changes the treatment of any
amount that is specifically provided for un-
der any provision of the Code or the reg-
ulations other than section 162(a) or sec-
tion 212 and the regulations under those
sections. For example, see section 263A
requiring taxpayers to capitalize the di-
rect and allocable indirect costs of property
produced and property acquired for resale.
(2)Materials and supplies. A material
or supply as defined in §1.162–3(c)(1) that
is acquired and used to improve a unit of
tangible property is subject to this section
and is not treated as a material or supply
under §1.162–3.
(3)Example.The following example
illustrates the rules of this paragraph (c):
Example.Railroad rolling stock.X is a railroad
that properly treats amounts paid for the rehabilitation
of railroad rolling stock as deductible expenses un-
der section 263(d). X is not required to capitalize the
amounts paid because nothing in this section changes
the treatment of amounts specifically provided for un-
der section 263(d).
(d)Requirement to capitalize amounts
paid for improvements. Except as pro-
vided in paragraph (h) or paragraph (n) of
this section or under §1.263(a)–1(f), a tax-
payer generally must capitalize the related
amounts (as defined in paragraph (g)(3) of
this section) paid to improve a unit of prop-
erty owned by the taxpayer. However, see
paragraph (f) of this section for the treat-
ment of amounts paid to improve leased
property. See section 263A for the require-
ment to capitalize the direct and alloca-
ble indirect costs of property produced by
the taxpayer and property acquired for re-
sale; section 1016 for adding capitalized
amounts to the basis of the unit of prop-
erty; and section 168 for the treatment of
additions or improvements for deprecia-
tion purposes. Forpurposes of this sec-
tion, a unit of property is improved if the
amounts paid for activities performed after
the property is placed in service by the tax-
payer—
(1) Are for a betterment to the unit of
property (see paragraph (j) of this section);
(2) Restore the unit of property (see
paragraph (k) of this section); or
(3) Adapt the unit of property to a new
or different use (see paragraph (l) of this
section).
(e)Determining the unit of prop-
erty—(1)In general. The unit of prop-
erty rules in this paragraph (e) apply
only for purposes of section 263(a) and
§§1.263(a)–1, 1.263(a)–2, 1.263(a)–3,
and 1.162–3. Unless otherwise specified,
the unit of property determination is based
upon the functional interdependence stan-
dard provided in paragraph (e)(3)(i) of this
section. However, special rules are pro-
vided for buildings (see paragraph (e)(2) of
this section), plant property (see paragraph
(e)(3)(ii) of this section), network assets
(see paragraph (e)(3)(iii) of this section),
October 21, 20133662013–43 I.R.B.

leased property (see paragraph (e)(2)(v)
of this section for leased buildings and
paragraph (e)(3)(iv) of this section for
leased property other than buildings), and
improvements to property (see paragraph
(e)(4) of this section). Additional rules
are provided if a taxpayer has assigned
different MACRS classes or depreciation
methods to components of property or
subsequently changes the class or depreci-
ation method of a component or other item
of property (see paragraph (e)(5) of this
section). Property that is aggregated or
subject to a general asset account election
or accounted for in a multiple asset ac-
count (that is, pooled) may not be treated
asasingleunitofproperty.
(2)Building—(i)In general. Except as
otherwise provided in paragraphs (e)(4),
and (e)(5)(ii) of this section, in the case of
a building (as defined in §1.48–1(e)(1)),
each building and its structural compo-
nents (as defined in §1.48–1(e)(2)) is a
single unit of property (“building”). See
paragraph (e)(2)(iii) of this section for
condominiums, paragraph (e)(2)(iv) of
this section for cooperatives, and para-
graph (e)(2)(v) of this section for leased
buildings.
(ii)Application of improvement rules to
a building.Anamountispaidtoimprove
a building under paragraph (d) of this sec-
tion if the amount is paid for an improve-
ment under paragraphs (j), (k), or para-
graph (l) of this section to any of the fol-
lowing:
(A)Building structure.A building
structure consists of the building (as de-
fined in §1.48–1(e)(1)), and its structural
components (as defined in §1.48–1(e)(2)),
other than the structural components des-
ignated as buildings systems in paragraph
(e)(2)(ii)(B) of this section.
(B)Building system.Each of the fol-
lowing structural components (as defined
in §1.48–1(e)(2)), including the com-
ponents thereof, constitutes a building
system that is separate from the building
structure, and to which the improvement
rules must be applied—
(1) Heating, ventilation, and air con-
ditioning (“HVAC”) systems (including
motors, compressors, boilers, furnace,
chillers, pipes, ducts, radiators);
(2) Plumbing systems (including pipes,
drains, valves, sinks, bathtubs, toilets, wa-
ter and sanitary sewer collection equip-
ment, and site utility equipment used to
distribute water and waste to and from the
property line and between buildings and
other permanent structures);
(3) Electrical systems (including
wiring, outlets, junction boxes, lighting
fixtures and associated connectors, and
site utility equipment used to distribute
electricity from the property line to and
between buildings and other permanent
structures);
(4) All escalators;
(5) All elevators;
(6) Fire-protection and alarm systems
(including sensing devices, computer con-
trols, sprinkler heads, sprinkler mains, as-
sociated piping or plumbing, pumps, vi-
sual and audible alarms, alarm control pan-
els, heat and smoke detection devices, fire
escapes, fire doors, emergency exit light-
ing and signage, and fire fighting equip-
ment, such as extinguishers, and hoses);
(7) Security systems for the protection
of the building and its occupants (includ-
ing window and door locks, security cam-
eras, recorders, monitors, motion detec-
tors, security lighting, alarm systems, en-
try and access systems, related junction
boxes, associated wiring and conduit);
(8) Gas distribution system (including
associated pipes and equipment used to
distribute gas to and from the property line
and between buildings or permanent struc-
tures); and
(9) Other structural components iden-
tified in published guidance in theFed-
eral Registeror in the Internal Revenue
Bulletin (see §601.601(d)(2)(ii)(b)ofthis
chapter) that are excepted from the build-
ing structure under paragraph (e)(2)(ii)(A)
of this section and are specifically desig-
nated as building systems under this sec-
tion.
(iii)Condominium—(A)In general.In
the case of a taxpayer that is the owner
of an individual unit in a building with
multiple units (such as a condominium),
the unit of property (“condominium”) is
the individual unit owned by the taxpayer
and the structural components (as defined
in §1.48–1(e)(2)) that are part of the unit.
(B)Application of improvement rules
to a condominium.Anamountispaid
to improve a condominium under para-
graph (d) of this section if the amount is
paid for an improvement under paragraphs
(j), (k), or paragraph (l) of this section to
the building structure (as defined in para-
graph (e)(2)(ii)(A) of this section) that is
part of the condominium or to the por-
tion of any building system (as defined in
paragraph (e)(2)(ii)(B) of this section) that
is part of the condominium. In the case
of the condominium management associ-
ation, the association must apply the im-
provement rules to the building structure
or to any building system described under
paragraphs (e)(2)(ii)(A) and (e)(2)(ii)(B)
of this section.
(iv)Cooperative—(A)In general.In
the case of a taxpayer that has an own-
ership interest in a cooperative housing
corporation, the unit of property (“coop-
erative”) is the portion of the building in
which the taxpayer has possessory rights
and the structural components (as defined
in §1.48–1(e)(2)) that are part of the por-
tion of the building subject to the tax-
payer’s possessory rights (cooperative).
(B)Application of improvement rules to
a cooperative. Anamountispaidtoim-
prove a cooperative under paragraph (d)
of this section if the amount is paid for
an improvement under paragraphs (j), (k),
or(l)ofthissectiontotheportionofthe
building structure (as defined in paragraph
(e)(2)(ii)(A) of this section) in which the
taxpayer has possessory rights or to the
portion of any building system (as defined
in paragraph (e)(2)(ii)(B) of this section)
that is part of the portion of the building
structure subject to the taxpayer’s posses-
sory rights. In the case of a cooperative
housing corporation, the corporation must
apply the improvement rules to the build-
ing structure or to any building system as
described under paragraphs (e)(2)(ii)(A)
and (e)(2)(ii)(B) of this section.
(v)Leased building—(A)In general.In
the case of a taxpayer that is a lessee of all
or a portion of a building (such as an office,
floor, or certain square footage), the unit
of property (“leased building property”)
is each building and its structural compo-
nents or the portion of each building sub-
ject to the lease and the structural compo-
nents associated with the leased portion.
(B)Application of improvement rules to
aleasedbuilding. An amount is paid to
improve a leased building property under
paragraphs (d) and (f)(2) of this section if
the amount is paid for an improvement, un-
der paragraphs (j), (k), or (l) of this section,
to any of the following:
(1)Entire building. In the case of a tax-
payer that is a lessee of an entire build-
ing, the building structure (as defined un-
2013–43 I.R.B.367October 21, 2013

der paragraph (e)(2)(ii)(A) of this section)
or any building system (as defined under
paragraph (e)(2)(ii)(B) of this section) that
is part of the leased building.
(2)Portion of a building. In the case of
a taxpayer that is a lessee of a portion of a
building (such as an office, floor, or certain
square footage), the portion of the build-
ing structure (as defined under paragraph
(e)(2)(ii)(A) of this section) subject to the
lease or the portion of any building system
(as defined under paragraph (e)(2)(ii)(B)
of this section) subject to the lease.
(3)Property other than building—(i)
In general. Except as otherwise provided
in paragraphs (e)(3), (e)(4), (e)(5), and
(f)(1) of this section, in the case of real
or personal property other than property
described in paragraph (e)(2) of this sec-
tion, all the components that are function-
ally interdependent comprise a single unit
of property. Components of property are
functionally interdependent if the placing
in service of one component by the tax-
payer is dependent on the placing in ser-
vice of the other component by the tax-
payer.
(ii)Plant property—(A)Definition.For
purposes of this paragraph (e), the term
plant propertymeans functionally inter-
dependent machinery or equipment, other
than network assets, used to perform an
industrial process, such as manufacturing,
generation, warehousing, distribution, au-
tomated materials handling in service in-
dustries, or other similar activities.
(B)Unit of property for plant property.
In the case of plant property, the unit of
property determined under the general rule
of paragraph (e)(3)(i) of this section is fur-
ther divided into smaller units comprised
of each component (or group of compo-
nents) that performs a discrete and major
function or operation within the function-
ally interdependent machinery or equip-
ment.
(iii)Network assets—(A)Definition.
For purposes of this paragraph (e), the
termnetwork assetsmeans railroad track,
oil and gas pipelines, water and sewage
pipelines, power transmission and distri-
bution lines, and telephone and cable lines
that are owned or leased by taxpayers in
each of those respective industries. The
term includes, for example, trunk and
feeder lines, pole lines, and buried conduit.
It does not include property that would be
included as building structure or building
systems under paragraphs (e)(2)(ii)(A)
and (e)(2)(ii)(B) of this section, nor does it
include separate property that is adjacent
to, but not part of a network asset, such as
bridges, culverts, or tunnels.
(B)Unit of property for network as-
sets.In the case of network assets, the
unit of property is determined by the
taxpayer’s particular facts and circum-
stances except as otherwise provided in
published guidance in theFederal Reg-
isteror in the Internal Revenue Bulletin
(see §601.601(d)(2)(ii)(b)ofthischapter).
For these purposes, the functional interde-
pendence standard provided in paragraph
(e)(3)(i) of this section is not determina-
tive.
(iv)Leased property other than build-
ings. In the case of a taxpayer that is a
lessee of real or personal property other
than property described in paragraph (e)(2)
of this section, the unit of property for the
leased property is determined under para-
graphs (e)(3)(i),(ii), (iii), and (e)(5) of this
section except that, after applying the ap-
plicable rules under those paragraphs, the
unit of property may not be larger than the
property subject to the lease.
(4)Improvements to property.Anim-
provement to a unit of property generally
is not a unit of property separate from the
unit of property improved. For the unit of
property for lessee improvements, see also
paragraph (f)(2)(ii)) of this section. If a
taxpayer elects to treat as a capital expen-
diture under §1.162–3(d) the amount paid
for a rotable spare part, temporary spare
part, or standby emergency spare part, and
such part is used in an improvement to a
unit of property, then for purposes of ap-
plying paragraph (d) of this section to the
unit of property improved, the part is not a
unit of property separate from the unit of
property improved.
(5)Additional rules—(i)Year placed in
service. Notwithstanding the unit of prop-
erty determination under paragraph (e)(3)
of this section, a component (or a group
of components) of a unit property must
be treated as a separate unit of property
if, at the time the unit of property is ini-
tially placed in service by the taxpayer,
the taxpayer has properly treated the com-
ponent as being within a different class
of property under section 168(e) (MACRS
classes) than the class of the unit of prop-
erty of which the component is a part, or
the taxpayer has properly depreciated the
component using a different depreciation
method than the depreciation method of
the unit of property of which the compo-
nent is a part.
(ii)Change in subsequent taxable year.
Notwithstanding the unit of property deter-
mination under paragraphs (e)(2), (3), (4),
or (5)(i) of this section, in any taxable year
after the unit of property is initially placed
in service by the taxpayer, if the taxpayer
or the Internal Revenue Service changes
the treatment of that property (or any por-
tion thereof) to a proper MACRS class or a
proper depreciation method (for example,
as a result of a cost segregation study or a
change in the use of the property), then the
taxpayer must change the unit of property
determination for that property (or the por-
tion thereof) under this section to be con-
sistent with the change in treatment for de-
preciation purposes. Thus, for example,
if a portion of a unit of property is prop-
erly reclassified to a MACRS class differ-
ent from the MACRS class of the unit of
property of which it was previously treated
as a part, then the reclassified portion of
the property shouldbe treated as a sepa-
rate unit of property for purposes of this
section.
(6)Examples.The following examples
illustrate the application of this paragraph
(e) and assume that the taxpayer has not
made a general asset account election with
regard to propertyor accounted for prop-
erty in a multiple asset account. In addi-
tion, unless the facts specifically indicate
otherwise, assume that the additional rules
in paragraph (e)(5) of this section do not
apply:
Example 1.Building systems. A owns an office
building that contains a HVAC system. The HVAC
system incorporates ten roof-mounted units that ser-
vice different parts of the building. The roof-mounted
units are not connected and have separate controls
and duct work that distribute the heated or cooled air
to different spaces in the building’s interior. A pays
an amount for labor and materials for work performed
on the roof-mounted units. Under paragraph (e)(2)(i)
of this section, A must treat the building and its struc-
tural components as a single unit of property. As pro-
vided under paragraph (e)(2)(ii) of this section, an
amount is paid to improve a building if it is for an im-
provement to the building structure or any designated
building system. Under paragraph (e)(2)(ii)(B)(
1)of
this section, the entire HVAC system, including all of
the roof-mounted units and their components, com-
prise a building system. Therefore, under paragraph
(e)(2)(ii) of this section, if an amount paid by A for
work on the roof-mountedunits is an improvement
(for example, a betterment) to the HVAC system,
October 21, 20133682013–43 I.R.B.

A must treat this amount as an improvement to the
building.
Example 2.Building systems. B owns a building
that it uses in its retail business. The building contains
two elevator banks in different locations in its build-
ing. Each elevator bank contains three elevators. B
pays an amount for labor and materials for work per-
formed on the elevators. Under paragraph (e)(2)(i) of
this section, B must treat the building and its struc-
tural components as a single unit of property. As pro-
vided under paragraph (e)(2)(ii) of this section, an
amountispaidtoimproveabuildingifitisforanim-
provement to the building structure or any designated
building system. Under paragraph (e)(2)(ii)(B)(
5)of
this section, all six elevators, including all their com-
ponents, comprise a building system. Therefore, un-
der paragraph (e)(2)(ii) of this section, if an amount
paid by B for work on the elevators is an improve-
ment (for example, a betterment) to the elevator sys-
tem, B must treat this amount as an improvement to
the building.
Example 3.Building structure and systems;
condominium
. C owns a condominium unit in a con-
dominium office building. C uses the condominium
unit in its business of providing medical services.
The condominium unit contains two restrooms, each
of which contains a sink, a toilet, water and drainage
pipes and other bathroom fixtures. C pays an amount
for labor and materials to perform work on the pipes,
sinks, toilets, and plumbing fixtures that are part of
the condominium. Under paragraph (e)(2)(iii) of
this section, C must treat the individual unit that it
owns, including the structural components that are
part of that unit, as a single unit of property. As pro-
vided under paragraph (e)(2)(iii)(B) of this section,
an amount is paid to improve the condominium if
it is for an improvement to the building structure
that is part of the condominium or to a portion of
any designated building system that is part of the
condominium. Under paragraph (e)(2)(ii)(B)(
2)of
this section, the pipes, sinks, toilets, and plumbing
fixtures that are part of C’s condominium comprise
the plumbing system for the condominium. There-
fore, under paragraph (e)(2)(iii) of this section, if an
amountpaidbyCforworkonpipes,sinks,toilets,
and plumbing fixtures is an improvement (for ex-
ample, a betterment) to the portion of the plumbing
system that is part of C’s condominium, C must treat
this amount as an improvement to the condominium.
Example 4.Building structure and systems; prop-
erty other than buildings
. D, a manufacturer, owns
a building adjacent to its manufacturing facility that
contains office space and related facilities for D’s
employees that manage and administer D’s manu-
facturing operations. The office building contains
equipment, such as desks, chairs, computers, tele-
phones, and bookshelves that are not building struc-
ture or building systems. D pays an amount to add
an extension to the office building. Under paragraph
(e)(2)(i) of this section, D must treat the building and
its structural components as a single unit of property.
As provided under paragraph (e)(2)(ii) of this sec-
tion, an amount is paid to improve a building if it is
for an improvement to the building structure or any
designated building system. Therefore, under para-
graph (e)(2)(ii) of this section, if an amount paid by
D for the addition of an extension to the office build-
ing is an improvement (forexample, a betterment)
to the building structure or any of the building sys-
tems, D must treat this amount as an improvement to
the building. In addition, because the equipment con-
tained within the office building constitutes property
other than the building, the units of property for the
office equipment are initially determined under para-
graph (e)(3)(i) of this section and are comprised of all
the components that are functionally interdependent
(for example, each desk, each chair, and each book
shelf).
Example 5. Plant property; discrete and major
function
. E is an electric utility company that oper-
ates a power plant to generate electricity. The power
plant includes a structure that is not a building un-
der §1.48–1(e)(1), and, among other things, one pul-
verizer that grinds coal, a single boiler that produces
steam, one turbine that converts the steam into me-
chanical energy, and one generator that converts me-
chanical energy into electrical energy. In addition, the
turbine contains a series of blades that cause the tur-
bine to rotate when affected by the steam. Because
the plant is composed of real and personal tangible
property other than a building, the unit of property
for the generating equipment is initially determined
under the general rule in paragraph (e)(3)(i) of this
section and is comprised of all the components that
are functionally interdependent. Under this rule, the
initial unit of property is the entire plant because the
components of the plant are functionally interdepen-
dent. However, because the power plant is plant prop-
erty under paragraph (e)(3)(ii) of this section, the ini-
tial unit of property is further divided into smaller
units of property by determining the components (or
groups of components) that perform discrete and ma-
jor functions within the plant. Under this paragraph,
E must treat the structure, the boiler, the turbine, the
generator, and the pulverizer each as a separate unit
of property because each of these components per-
forms a discrete and major function within the power
plant. E may not treat components, such as the tur-
bine blades, as separate units of property because
each of these components does not perform a discrete
and major function within the plant.
Example 6.Plant property; discrete and major
function
. F is engaged in a uniform and linen rental
business. F owns and operates a plant that utilizes
many different machines and equipment in an as-
sembly line-like process to treat, launder, and pre-
pare rental items for its customers. F utilizes two
laundering lines in its plant, each of which can op-
erate independently. One line is used for uniforms
and another line is used for linens. Both lines incor-
porate a sorter, boiler, washer, dryer, ironer, folder,
and waste water treatment system. Because the laun-
dering equipment contained within the plant is prop-
erty other than a building, the unit of property for
the laundering equipment is initially determined un-
der the general rule in paragraph (e)(3)(i) of this sec-
tion and is comprised of all the components that are
functionally interdependent. Under this rule, the ini-
tial units of property are each laundering line be-
cause each line is functionally independent and is
comprised of components that are functionally inter-
dependent. However, because each line is comprised
of plant property under paragraph (e)(3)(ii) of this
section, F must further divide these initial units of
property into smaller units of property by determin-
ing the components (or groups of components) that
perform discrete and major functions within the line.
Under paragraph (e)(3)(ii) of this section, F must treat
each sorter, boiler, washer, dryer, ironer, folder, and
waste water treatment system in each line as a sep-
arate unit of property because each of these compo-
nents performs a discrete and major function within
the line.
Example 7.Plant property; industrial process.
G operates a restaurant that prepares and serves food
to retail customers. Within its restaurant, G has
a large piece of equipment that uses an assembly
line-like process to prepare and cook tortillas that
G serves only to its restaurant customers. Because
the tortilla-making equipment is property other than
a building, the unit of property for the equipment is
initially determined under the general rule in para-
graph (e)(3)(i) of this section and is comprised of all
the components that are functionally interdependent.
Under this rule, the initial unit of property is the
entire tortilla-making equipment because the vari-
ous components of the equipment are functionally
interdependent. The equipment is not plant property
under paragraph (e)(3)(ii) of this section because the
equipment is not used in an industrial process, as
it performs a small-scale function in G’s restaurant
operations. Thus, G is not required to further divide
the equipment into separate units of property based
on the components that perform discrete and major
functions.
Example 8.Personal property.Hownslocomo-
tives that it uses in its railroad business. Each loco-
motive consists of various components, such as an
engine, generators, batteries, and trucks. H acquired
a locomotive with all its components. Because H’s
locomotive is property other than a building, the ini-
tial unit of property is determined under the general
rule in paragraph (e)(3)(i) of this section and is com-
prised of the components that are functionally inter-
dependent. Under paragraph (e)(3)(i) of this section,
the locomotive is a single unit of property because it
consists entirely of components that are functionally
interdependent.
Example 9.Personal property. J provides le-
gal services to its clients. J purchased a laptop com-
puter and a printer for its employees to use in provid-
ing legal services. Because the computer and printer
are property other than a building, the initial units
of property are determined under the general rule in
paragraph (e)(3)(i) of this section and are comprised
of the components that are functionally interdepen-
dent. Under paragraph (e)(3)(i) of this section, the
computer and the printer are separate units of prop-
erty because the computer and the printer are not
components that are functionally interdependent (that
is, the placing in service of the computer is not depen-
dent on the placing in service of the printer).
Example 10.Building structure and systems;
leased building
. K is a retailer of consumer products.
K conducts its retail sales in a building that it leases
from L. The leased building consists of the build-
ing structure (including the floor, walls, and roof)
and various building systems, including a plumbing
system, an electrical system, an HVAC system, a
security system, and a fire protection and prevention
system. K pays an amount for labor and materials
to perform work on the HVAC system of the leased
building. Under paragraph (e)(2)(v)(A) of this sec-
tion, because K leases the entire building, K must
treat the leased building and its structural compo-
nents as a single unit of property. As provided under
paragraph (e)(2)(v)(B) of this section, an amount
2013–43 I.R.B.369October 21, 2013

is paid to improve a leased building property if it
is for an improvement (for example, a betterment)
to the leased building structure or to any building
system within the leased building. Therefore, un-
der paragraphs (e)(2)(v)(B)(
1) and (e)(2)(ii)(B)(1)
of this section, if an amount paid by K for work
on the HVAC system is for an improvement to the
HVAC system in the leased building, K must treat
this amount as an improvement to the entire leased
building property.
Example 11.Production of real property related
to leased property
. Assume the same facts as in
Example 10, except that K receives a construction
allowance from L, and K uses the construction al-
lowance to build a driveway adjacent to the leased
building. Assume that under the terms of the lease,
K, the lessee, is treated as the owner of any property
that it constructs on or nearby the leased building.
Also assume that section 110 does not apply to the
construction allowance. Finally, assume that the
driveway is not plant property or a network asset.
Because the construction of the driveway consists of
the production of real property other than a building,
all the components of thedriveway are functionally
interdependent and are a single unit of property under
paragraphs (e)(3)(i) and (e)(3)(iv) of this section.
Example 12.Leasehold improvements; construc-
tion allowance used for lessor-owned improvements
.
Assume the same facts as
Example 11, except that,
under the terms of the lease, L, the lessor, is treated
as the owner of any property constructed on the leased
premises. Because L, the lessor, is the owner of the
driveway and the driveway is real property other than
a building, all the components of the driveway are
functionally interdependent and are a single unit of
property under paragraph (e)(3)(i) of this section.
Example 13.Buildings and structural compo-
nents; leased office space
. M provides consulting ser-
vices to its clients. M conducts its consulting services
business in two office spaces in the same building,
each of which it leases from N under separate lease
agreements. Each office space contains a separate
HVAC system, which is part of the leased property.
Both lease agreements provide that M is responsible
for maintaining, repairing, and replacing the HVAC
system that is part of the leased property. M pays
amounts to perform work on the HVAC system in
each office space. Because M leases two separate of-
fice spaces subject to two leases, M must treat the
portion of the building structure and the structural
components subject to each lease as a separate unit of
property under paragraph (e)(2)(v)(A) of this section.
As provided under paragraph (e)(2)(v)(B) of this sec-
tion,anamountispaidtoimprove a leased building
property, if it is for an improvement to the leased por-
tion of the building structure or the portion of any
designated building system subject to each lease. Un-
der paragraphs (e)(2)(v)(B)(
1) and (e)(2)(ii)(B)(1)of
this section, M must treat the HVAC system associ-
ated with each leased office space as a building sys-
tem of that leased building property. Thus, M must
treat the HVAC system associated with the first leased
office space as a building system of the first leased
office space and the HVAC system associated with
the second leased office space as a building system
of the second leased office space. Under paragraph
(e)(2)(v)(B) of this section, if the amount paid by M
for work on the HVAC system in one leased office
space is for an improvement (for example, a better-
ment) to the HVAC system that is part of that leased
space, then M must treat the amount as an improve-
ment to that individual leased property.
Example 14.Leased property; personal prop-
erty
. N is engaged in the business of transporting pas-
sengers on private jet aircraft. To conduct its busi-
ness, N leases several aircraft from O. Under para-
graph (e)(3)(iv) of this section (referencing paragraph
(e)(3)(i) of this section), N must treat all of the com-
ponents of each leased aircraft that are functionally
interdependent as a single unit of property. Thus, N
must treat each leased aircraft as a single unit of prop-
erty.
Example 15.Improvement property.(i)Pisare-
tailer of consumer products. In Year 1, P purchases
a building from Q, which P intends to use as a retail
sales facility. Under paragraph (e)(2)(i) of this sec-
tion, P must treat the building and its structural com-
ponents as a single unit of property. As provided un-
der paragraph (e)(2)(ii) of this section, an amount is
paid to improve a building if it is for an improvement
to the building structure or any designated building
system.
(ii) In Year 2, P pays an amount to construct an ex-
tension to the building to be used for additional ware-
house space. Assume that the extension involves the
addition of walls, floors, roof, and doors, but does
not include the addition or extension of any building
systems described in paragraph (e)(2)(ii)(B) of this
section. Also assume that the amount paid to build
the extension is a betterment to the building structure
under paragraph (j) of this section, and is therefore
treated as an amount paid for an improvement to the
entire building under paragraph (e)(2)(ii) of this sec-
tion. Accordingly, P capitalizes the amount paid as an
improvement to the building under paragraph (d) of
this section. Under paragraph (e)(4) of this section,
the extension is not a unit of property separate from
the building, the unit of property improved. Thus,
to determine whether any future expenditure consti-
tutes an improvement to the building under paragraph
(e)(2)(ii) of this section, P must determine whether
the expenditure constitutes an improvement to the
building structure, including the building extension,
or to any of the designated building systems.
Example 16.Additional rules; year placed in ser-
vice
. R is engaged in the business of transporting
freight throughout the United States. To conduct its
business, R owns a fleet of truck tractors and trailers.
Each tractor and trailer is comprised of various com-
ponents, including tires. R purchased a truck tractor
with all of its components, including tires. The trac-
tor tires have an average useful life to R of more than
one year. At the time R placed the tractor in service, it
treated the tractor tires as a separate asset for depreci-
ation purposes under section 168. R properly treated
the tractor (excluding the cost of the tires) as 3-year
property and the tractor tires as 5-year property under
section 168(e). Because R’s tractor is property other
than a building, the initial units of property for the
tractor are determined under the general rule in para-
graph (e)(3)(i) of this section and are comprised of all
the components that are functionally interdependent.
Under this rule, R must treat the tractor, including its
tires, as a single unit of property because the tractor
and the tires are functionally interdependent (that is,
the placing in service of the tires is dependent upon
the placing in service of the tractor). However, under
paragraph (e)(5)(i) of this section, R must treat the
tractor and tires as separate units of property because
R properly treated the tires as being within a different
class of property under section 168(e).
Example 17. Additional rules; change in subse-
quent year
. S is engaged in the business of leasing
nonresidential real property to retailers. In Year 1,
S acquired and placed in service a building for use
in its retail leasing operation. In Year 5, to accom-
modate the needs of a new lessee, S incurred costs to
improve the building structure. S capitalized the costs
of the improvement under paragraph (d) of this sec-
tion and depreciated the improvement in accordance
with section 168(i)(6) as nonresidential real property
under section 168(e). In Year 7, S determined that the
structural improvement made in Year 5 qualified un-
der section 168(e)(8) as qualified retail improvement
property and, therefore, was 15-year property under
section 168(e). In Year 7, S changed its method of
accounting to use a 15-year recovery period for the
improvement. Under paragraph (e)(5)(ii) of this sec-
tion, in Year 7, S must treat the improvement as a unit
of property separate from the building.
Example 18.Additional rules; change in sub-
sequent year
. In Year 1, T acquired and placed in
service a building and parking lot for use in its re-
tail operations. Under §1.263(a)–2 of the regulations,
T capitalized the cost of the building and the park-
ing lot and began depreciating the building and the
parking lot as nonresidential real property under sec-
tion 168(e). In Year 3, T completed a cost segrega-
tion study under which it properly determined that the
parking lot qualified as 15-year property under sec-
tion 168(e). In Year 3, T changed its method of ac-
counting for the parking lot to use a 15-year recovery
period and the 150-percent declining balance method
of depreciation. Under paragraph (e)(5)(ii) of this
section, beginning in Year 3, T must treat the parking
lot as a unit of property separate from the building.
Example 19.Additional rules; change in sub-
sequent year
. In Year 1, U acquired and placed in
service a building for use in its manufacturing busi-
ness. U capitalized the costs allocable to the build-
ing’s wiring separately from the building and depre-
ciated the wiring as 7-year property under section
168(e). U capitalized the cost of the building and all
other structural components of the building and be-
gan depreciating them as nonresidential real property
under section 168(e). In Year 3, U completed a cost
segregation study under which it properly determined
that the wiring is a structural component of the build-
ing and, therefore, shouldhave been depreciated as
nonresidential real property. In Year 3, U changed
its method of accounting to treat the wiring as non-
residential real property. Under paragraph (e)(5)(ii)
of this section, U must change the unit of property
for the wiring in a manner that is consistent with
the change in treatment for depreciation purposes.
Therefore, U must change the unit of property for
the wiring to treat it as a structural component of the
building, and as part of the building unit of property,
in accordance with paragraph (e)(2)(i) of this section.
(f)Improvements to leased prop-
erty—(1)In general. Except as provided
in paragraph (h) of this section (safe
harbor for small taxpayers) and under
§1.263(a)–1(f) (de minimissafe harbor),
this paragraph (f) provides the exclusive
rules for determining whether amounts
October 21, 20133702013–43 I.R.B.

paid by a taxpayer are for an improvement
to a leased property and must be capital-
ized. In the case of a leased building or
a leased portion of a building, an amount
is paid to improve a leased property if the
amount is paid for an improvement to any
of the properties specified in paragraph
(e)(2)(ii) of this section (for lessor im-
provements) or in paragraph (e)(2)(v)(B)
of this section (for lessee improvements,
except as provided in paragraph (f)(2)(ii)
of this section). Section 1.263(a)–4 does
not apply to amounts paid for improve-
ments to leased property or to amounts
paid for the acquisition or production of
leasehold improvement property.
(2)Lessee improvements—(i)Require-
ment to capitalize. A taxpayer lessee must
capitalize the related amounts (see para-
graph (g)(3) of this section) that it pays to
improve (as defined under paragraph (d)
of this section) a leased property except
to the extent that section 110 applies to
a construction allowance received by the
lessee for the purpose of such improve-
ment or when the improvement constitutes
a substitute for rent. See §1.61–8(c) for
the treatment of lesseeexpenditures that
constitute a substitute for rent. A tax-
payer lessee must also capitalize the re-
lated amounts that a lessor pays to im-
prove (as defined under paragraph (d) of
this section) a leased property if the lessee
is the owner of the improvement, except
to the extent that section 110 applies to
a construction allowance received by the
lessee for the purpose of such improve-
ment. An amount paid for a lessee im-
provement under this paragraph (f)(2)(i) is
treated as an amount paid to acquire or pro-
duce a unit of real or personal property un-
der §1.263(a)–2(d)(1) of the regulations.
(ii)Unit of property for lessee im-
provements. For purposes of determining
whether an amount paid by a lessee con-
stitutes a lessee improvement to a leased
property under paragraph (f)(2)(i) of this
section, the unit of property and the im-
provement rules are applied to the leased
property in accordance with paragraph
(e)(2)(v) (leased buildings) or paragraph
(e)(3)(iv) (leased property other than
buildings) of this section and include pre-
vious lessee improvements. However, if
a lessee improvement is comprised of an
entire building erected on leased property,
then the unit of property for the building
and the application of the improvement
rules to the building are determined under
paragraphs (e)(2)(i) and (e)(2)(ii) of this
section.
(3)Lessor improvements—(i)Require-
ment to capitalize. A taxpayer lessor must
capitalize the related amounts (see para-
graph (g)(3) of this section) that it pays
directly, or indirectly through a construc-
tion allowance to the lessee, to improve
(as defined in paragraph (d) of this section)
a leased property when the lessor is the
owner of the improvement or to the extent
that section 110 applies to the construc-
tion allowance. A lessor must also capital-
ize the related amounts that the lessee pays
to improve a leased property (as defined
in paragraph (e) of this section) when the
lessee’s improvement constitutes a substi-
tute for rent. See §1.61–8(c) for treatment
of expenditures by lessees that constitute
a substitute for rent.Amounts capitalized
by the lessor under this paragraph (f)(3)(i)
may not be capitalized by the lessee. If
a lessor improvement is comprised of an
entire building erected on leased property,
then the amount paid for the building is
treated as an amount paid by the lessor to
acquire or produce a unit of property under
§1.263(a)–2(d)(1). See paragraphs (e)(2)
of this section for the unit of property for
a building and paragraph (e)(3) of this sec-
tion for the unit of property for real or per-
sonal property other than a building.
(ii)Unit of property for lessor improve-
ments. In general, an amount capitalized
as a lessor improvement under paragraph
(f)(3)(i) of this section is not a unit of prop-
erty separate from the unit of property im-
proved. See paragraph (e)(4) of this sec-
tion. However, if a lessor improvement
is comprised of an entire building erected
on leased property, then the unit of prop-
erty for the building and the application of
the improvement rules to the building are
determined under paragraphs (e)(2)(i) and
(e)(2)(ii) of this section.
(4)Examples. The following examples
illustrate the application of this paragraph
(f) and do not address whether capitaliza-
tion is required under another provision of
the Code (for example, section 263A). For
purposes of the following examples, as-
sume that section 110 does not apply to the
lessee and the amounts paid by the lessee
are not a substitute for rent.
Example 1.Lessee improvements; additions to
building
. (i) T is a retailer of consumer products.
In Year 1, T leases a building from L, which T in-
tends to use as a retail sales facility. The leased build-
ing consists of the building structure under paragraph
(e)(2)(ii)(A) of this section and various building sys-
tems under paragraph (e)(2)(ii)(B) of this section, in-
cluding a plumbing system, an electrical system, and
an HVAC system. Under the terms of the lease, T
is permitted to improve the building at its own ex-
pense. Under paragraph (e)(2)(v)(A) of this section,
because T leases the entirebuilding, T must treat the
leased building and its structural components as a sin-
gle unit of property. As provided under paragraph
(e)(2)(v)(B)(
1) of this section, an amount is paid to
improve a leased building property if the amount is
paid for an improvement to the leased building struc-
ture or to any building system within the leased build-
ing. Therefore, under paragraphs (e)(2)(v)(B)(
1)and
(e)(2)(ii) of this section, if T pays an amount that im-
proves the building structure, the plumbing system,
the electrical system, or the HVAC system, then T
must treat this amount as an improvement to the en-
tire leased building property.
(ii) In Year 2, T pays an amount to construct an ex-
tension to the building to be used for additional ware-
house space. Assume that this amount is for a better-
ment (as defined under paragraph (j) of this section)
to T’s leased building structure and does not affect
any building systems. Accordingly, the amount that
T pays for the building extension is for a betterment
to the leased building structure, and thus, under para-
graph (e)(2)(v)(B)(
1) of this section, is treated as an
improvement to the entire leased building under para-
graph (d) of this section. Because T, the lessee, paid
an amount to improve a leased building property, T is
required to capitalize the amount paid for the build-
ing extension as a leasehold improvement under para-
graph (f)(2)(i) of this section. In addition, paragraph
(f)(2)(i) of this section requires T to treat the amount
paid for the improvement as the acquisition or pro-
duction of a unit of property (leasehold improvement
property) under §1.263(a)–2(d)(1).
(iii) In Year 5, T pays an amount to add a large
overhead door to the building extension that it con-
structed in Year 2 to accommodate the loading of
larger products into the warehouse space. Under
paragraph (f)(2)(ii) of this section, to determine
whether the amount paid by T is for a leasehold
improvement, the unit of property and the improve-
ment rules are applied in accordance with paragraph
(e)(2)(v) of this section and include T’s previous
improvements to the leased property. Therefore,
under paragraph (e)(2)(v)(A) of this section, the unit
of property is the entire leased building, including
the extension built in Year 2. In addition, under
paragraph (e)(2)(v)(B) of this section, the leased
building property is improved if the amount is paid
for an improvement to the building structure or any
building system. Assume that the amount paid to
add the overhead door is for a betterment, under
paragraph (j) of this section, to the building structure,
which includes the extension. Accordingly, T must
capitalize the amounts paid to add the overhead door
as a leasehold improvement to the leased building
property. In addition, paragraph (f)(2)(i) of this
section requires T to treat the amount paid for the
improvement as the acquisition or production of a
unit of property (leasehold improvement property)
under §1.263(a)–2(d)(1). However, to determine
whetherafutureamountpaidbyTisforaleasehold
improvement to the leased building, the unit of prop-
2013–43 I.R.B.371October 21, 2013

erty and the improvement rules are again applied in
accordance with paragraph (e)(2)(v) of this section
and include the new overhead door.
Example 2.Lessee improvements; additions to
certain structural components of buildings
.(i)As-
sume the same facts as
Example 1except that in Year
2, T also pays an amount to construct an extension
of the HVAC system into the building extension. As-
sume that the extension is a betterment, under para-
graph (j) of this section, to the leased HVAC system
(a building system under paragraph (e)(2)(ii)(B)(
1)of
this section). Accordingly, the amount that T pays
for the extension of the HVAC system is for a better-
ment to the leased building system, the HVAC sys-
tem, and thus, under paragraph (e)(2)(v)(B)(
1)ofthis
section, is treated as an improvement to the entire
leased building property under paragraph (d) of this
section. Because T, the lessee, pays an amount to im-
prove a leased building property, T is required to cap-
italize the amount paid as a leasehold improvement
under paragraph (f)(2)(i) of this section. Under para-
graph (f)(2)(i) of this section, T must treat the amount
paid for the HVAC extension as the acquisition and
production of a unit of property (leasehold improve-
ment property) under §1.263(a)–2(d)(1).
(ii) In Year 5, T pays an amount to add an ad-
ditional chiller to the portion of the HVAC system
that it constructed in Year 2 to accommodate the cli-
mate control requirements for new product offerings.
Under paragraph (f)(2)(ii) of this section, to deter-
mine whether the amount paid by T is for a leasehold
improvement, the unit of property and the improve-
ment rules are applied inaccordance with paragraph
(e)(2)(v) of this section and include T’s previous im-
provements to the leased building property. There-
fore, under paragraph (e)(2)(v)(B) of this section, the
leased building property is improved if the amount is
paid for an improvement to the building structure or
any building system. Assume that the amount paid to
add the chiller is for a betterment, under paragraph
(j) of this section, to the HVAC system, which in-
cludes the extension of the system in Year 2. Ac-
cordingly, T must capitalize the amounts paid to add
the chiller as a leasehold improvement to the leased
building property. In addition, paragraph (f)(2)(i) of
this section requires T to treat the amount paid for
the chiller as the acquisition or production of a unit
of property (leasehold improvement property) under
§1.263(a)–2(d)(1). However, to determine whether a
future amount paid by T is for a leasehold improve-
ment to the leased building, the unit of property and
the improvement rules are again applied in accor-
dance with paragraph (e)(2)(v) of this section and in-
clude the new chiller.
Example 3.Lessor Improvements; additions to
building
. (i) T is a retailer of consumer products. In
Year 1, T leases a building from L, which T intends
to use as a retail sales facility. Pursuant to the lease,
L provides a construction allowance to T, which T
intends to use to construct an extension to the retail
sales facility for additional warehouse space. As-
sume that the amount paid for any improvement to the
building does not exceed the construction allowance
and that L is treated as the owner of any improvement
to the building. Under paragraph (e)(2)(i) of this sec-
tion, L must treat the building and its structural com-
ponents as a single unit of property. As provided un-
der paragraph (e)(2)(ii) of this section, an amount is
paid to improve a building if it is paid for an improve-
ment to the building structure or to any building sys-
tem.
(ii) In Year 2, T uses L’s construction allowance to
construct an extension to the leased building to pro-
vide additional warehouse space in the building. As-
sume that the extension is a betterment (as defined
under paragraph (j) of this section) to the building
structure, and therefore, the amount paid for the ex-
tension results in an improvement to the building un-
der paragraph (d) of this section. Under paragraph
(f)(3)(i) of this section, L, the lessor and owner of the
improvement, must capitalize the amounts paid to T
to construct the extension to the retail sales facility. T
is not permitted to capitalize the amounts paid for the
lessor-owned improvement. Finally, under paragraph
(f)(3)(ii) of this section, the extension to L’s building
is not a unit of property separate from the building
and its structural components.
Example 4.Lessee property; personal property
added to leased building
. T is a retailer of consumer
products. T leases a building from L, which T intends
to use as a retail sales facility. Pursuant to the lease, L
provides a construction allowance to T, which T uses
to acquire and construct partitions for fitting rooms,
counters, and shelving. Assume that each partition,
counter, and shelving unit is a unit of property under
paragraph (e)(3) of this section. Assume that for Fed-
eral income tax purposes T is treated as the owner of
the partitions, counters, and shelving. T’s expendi-
tures for the partitions, counters, and shelving are not
improvements to the leased property under paragraph
(d) of this section, but rather constitute amounts paid
to acquire or produce separate units of personal prop-
erty under §1.263(a)–2(d)(1).
Example 5. Lessor property; buildings on leased
property
. L is the owner of a parcel of unimproved
real property that L leases to T. Pursuant to the lease,
L provides a construction allowance to T of $500,000,
which T agrees to use to construct a building costing
not more than $500,000 on the leased real property
and to lease the building from L after it is constructed.
Assume that for Federal income tax purposes, L is
treated as the owner of the building that T will con-
struct. T uses the $500,000 to construct the building
as required under the lease. The building consists of
the building structure and the following building sys-
tems: (1) a plumbing system; (2) an electrical sys-
tem; and (3) an HVAC system. Because L provides
a construction allowance to T to construct a build-
ing and L is treated as the owner of the building, L
must capitalize the amounts that it pays indirectly to
T to construct the building as a lessor improvement
under paragraph (f)(3)(i) of this section. In addition,
the amounts paid by L for the construction allowance
are treated as amounts paid by L to acquire and pro-
duce the building under §1.263(a)–2(d)(1). Further,
under paragraph (e)(2)(i) of this section, L must treat
the building and its structural components as a sin-
gle unit of property. Under paragraph (f)(3)(i) of this
section, T, the lessee, may not capitalize the amounts
paid (with the construction allowance received from
L) for construction of the building.
Example 6.Lessee contribution to construction
costs
. Assume the same facts as inExample 5, except
T spends $600,000 to construct the building. T uses
the $500,000 construction allowance provided by L
plus $100,000 of its own funds to construct the build-
ing that L will own pursuant to the lease. Also assume
that the additional $100,000 that T pays is not a sub-
stitute for rent. For the reasons discussed in
Example
5
, L must capitalize the $500,000 it paid T to con-
struct the building under §1.263(a)–2(d)(1). In addi-
tion, because T spends its own funds to complete the
building, T has a depreciable interest of $100,000 in
the building and must capitalize the $100,000 it paid
to construct the building as a leasehold improvement
under §1.263(a)–2(d)(1) of the regulations. Under
paragraph (e)(2)(i) of this section, L must treat the
building as a single unit of property to the extent of
its depreciable interest of $500,000 In addition, un-
der paragraphs (f)(2)(ii) and (e)(2)(i) of this section, T
must also treat the building as a single unit of property
to the extent of its depreciable interest of $100,000.
(g)Special rules for determining im-
provement costs—(1)Certain costs in-
curred during an improvement—(i)In
general. A taxpayer must capitalize all
the direct costs of an improvement and all
the indirect costs (including, for example,
otherwise deductible repair costs) that di-
rectly benefit or areincurred by reason
of an improvement. Indirect costs arising
from activities that do not directly bene-
fit and are not incurred by reason of an
improvement are not required to be capi-
talized under section 263(a), regardless of
whether the activitiesare performed at the
same time as an improvement.
(ii)Exception for individuals’ resi-
dences. A taxpayer who is an individual
may capitalize amounts paid for repairs
and maintenance that are made at the same
time as capital improvements to units of
property not used in the taxpayer’s trade
or business or for the production of in-
come if the amounts are paid as part of an
improvement (for example, a remodeling)
of the taxpayer’s residence.
(2)Removal Costs—(i)In general.If
a taxpayer disposes of a depreciable asset,
including a partial disposition under Prop.
Reg. §1.168(i)–1(e)(2)(ix) (September
19, 2013), or Prop. Reg. §1.168(i)–8(d)
(September 19, 2013), for Federal income
tax purposes and has taken into account
the adjusted basis of the asset or com-
ponent of the asset inrealizing gain or
loss, then the costs of removing the as-
set or component are not required to be
capitalized under this section. If a de-
preciable asset is included in a general
asset account under section 168(i)(4),
and neither the regulations under section
168(i)(4) and §1.168(i)–1T(e)(3) nor Prop.
Reg. §1.168(i)–1(e)(3) (September 19,
2013), apply to a disposition of such as-
set, or a portion of such asset under Prop.
Reg. §1.168(i)–1(e)(2)(ix) (September 19,
2013), a loss is treated as being realized
October 21, 20133722013–43 I.R.B.

in the amount of zero upon the disposition
of the asset solely for purposes of this
paragraph (g)(2)(i). If a taxpayer disposes
of a component of a unit of property, but
the disposal of the component is not a
disposition for Federal tax purposes, then
the taxpayer must deduct or capitalize the
costs of removing the component based on
whether the removal costs directly benefit
or are incurred by reason of a repair to
the unit of property or an improvement to
the unit of property. But see §1.280B–1
for the rules applicable to demolition of
structures.
(ii)Examples. The following exam-
ples illustrate the application of paragraph
(g)(2)(i) of this section and, unless other-
wise stated, do not address whether cap-
italization is required under another pro-
vision of this section or another provision
of the Code (for example, section 263A).
For purposes of the following examples,
assume that Prop. Reg. §1.168(i)–1(e)
(September 19, 2013), or Prop. Reg.
§1.168(i)–8 (September 19, 2013), applies
and that §1.280B–1 does not apply.
Example 1.Component removed during improve-
ment; no disposition
. X owns a factory building
with a storage area on the second floor. X pays an
amount to remove the original columns and girders
supporting the second floor and replace them with
new columns and girders to permit storage of sup-
plies with a gross weight 50 percent greater than
the previous load-carrying capacity of the storage
area. Assume that the replacement of the columns
and girders constitutes a betterment to the building
structure and is therefore an improvement to the
building unit of property under paragraphs (d)(1)
and (j) of this section. Assume that X disposes of
the original columns and girders and the disposal of
these structural components is not a disposition under
Prop. Reg. §1.168(i)–1(e) (September 19, 2013),
or Prop. Reg. §1.168(i)–8 (September 19, 2013).
Under paragraphs (g)(2)(i) and (j) of this section, the
amount paid to remove the columns and girders must
be capitalized as a cost of the improvement, because
it directly benefits and is incurred by reason of the
improvement to the building.
Example 2.Component removed during improve-
ment; disposition
.AssumethesamefactsasEx-
ample 1
, except X disposes of the original columns
and girders and elects to treat the disposal of these
structural components as a partial disposition of the
factory building under Prop. Reg. §1.168(i)–8(d)
(September 19, 2013), taking into account the ad-
justed basis of the components in realizing loss on the
disposition. Under paragraph (g)(2)(i) of this section,
the amount paid to remove the columns and girders is
not required to be capitalized as part of the cost of the
improvement regardless of their relation to the im-
provement. However, all the remaining costs of re-
placing the columns and girders must be capitalized
as improvements to the building unit of property un-
der paragraphs (d)(1), (j), and (g)(1) of this section.
Example 3.Component removed during repair
or maintenance; no disposition
. Y owns a building
in which it conducts its retail business. The roof over
Y’s building is covered with shingles. Over time, the
shingles begin to wear and Y begins to experience
leaks into its retail premises. However, the build-
ing still functions in Y’s business. To eliminate the
problems, a contractor recommends that Y remove
the original shingles and replace them with new shin-
gles. Accordingly, Y pays the contractor to replace
the old shingles with new but comparable shingles.
The new shingles are comparable to original shin-
gles but correct the leakage problems. Assume that
Y disposes of the original shingles, and the disposal
of these shingles is not a disposition under Prop. Reg.
§1.168(i)–1(e) (September 19, 2013), or Prop. Reg.
§1.168(i)–8 (September 19, 2013). Assume that re-
placement of old shingles with new shingles to cor-
rect the leakage is not a betterment or a restoration of
the building structure or systems under paragraph (j)
or (k) of this section and does not adapt the building
structure or systems to a new or different use under
paragraph (l) of this section. Thus, the amounts paid
by Y to replace the shingles are not improvements to
the building unit of property under paragraph (d) of
this section. Under paragraph (g)(2)(i) of this section,
the amounts paid to remove the shingles are not re-
quired to be capitalized because they directly benefit
and are incurred by reason of repair or maintenance
to the building structure.
Example 4.Component removed with disposition
and restoration
. Assume the same facts asExample
3
except Y disposes of the original shingles, and Y
elects to treat the disposal of these components as a
partial disposition of the building under Prop. Reg.
§1.168(i)–8(d) (September 19, 2013), and deducts the
adjusted basis of the components as a loss on the dis-
position. Under paragraph (k)(1)(i) of this section,
amounts paid for replacement of the shingles con-
stitute a restoration of thebuilding structure because
the amounts are paid for the replacement of a com-
ponent of the structure and the taxpayer has properly
deducted a loss for that component. Thus, under para-
graphs (d)(2) and (k) of this section, Y is required to
capitalize the amounts paid for the replacement of the
shingles as an improvement to the building unit of
property. However, under paragraph (g)(2)(i) of this
section, the amounts paid by Y to remove the original
shingles are not required to be capitalized as part of
the costs of the improvement, regardless of their re-
lation to the improvement.
(3)Related amounts. For purposes of
paragraph (d) of this section, amounts
paid to improve a unit of property include
amounts paid over a period of more than
one taxable year. Whether amounts are
related to the same improvement depends
on the facts and circumstances of the ac-
tivities being performed.
(4)Compliance with regulatory re-
quirements. For purposes of this section,
a Federal, state, or local regulator’s re-
quirement that a taxpayer perform certain
repairs or maintenance on a unit of prop-
erty to continue operating the property is
not relevant in determining whether the
amount paid improves the unit of property.
(h)Safe harbor for small taxpay-
ers—(1)In general. A qualifying taxpayer
(as defined in paragraph (h)(3) of this
section) may elect to not apply paragraph
(d)orparagraph(f)ofthissectiontoan
eligible building property (as defined in
paragraph (h)(4) of this section) if the total
amount paid during the taxable year for
repairs, maintenance, improvements, and
similar activities performed on the eligi-
ble building property does not exceed the
lesser of—
(i) 2 percent of the unadjusted basis (as
defined under paragraph (h)(5) of this sec-
tion) of the eligible building property; or
(ii) $10,000.
(2)Application with other safe harbor
provisions. For purposes of paragraph
(h)(1) of this section, amounts paid for
repairs, maintenance, improvements, and
similar activities performed on eligible
building property include those amounts
not capitalized under thede minimissafe
harbor election under §1.263(a)–1(f) and
those amounts deemed not to improve
property under the safe harbor for routine
maintenance under paragraph (i) of this
section.
(3)Qualifying taxpayer—(i)In general.
For purposes of this paragraph (h), the
termqualifying taxpayermeans a taxpayer
whose average annual gross receipts as de-
termined under this paragraph (h)(3) for
the three preceding taxable years is less
than or equal to $10,000,000.
(ii)Application to new taxpayers.If
a taxpayer has been in existence for less
than three taxable years, the taxpayer de-
termines its average annual gross receipts
for the number of taxable years (including
short taxable years) that the taxpayer (or its
predecessor) has been in existence.
(iii)Treatment of short taxable year.In
the case of any taxable year of less than
12 months (a short taxable year), the gross
receipts shall be annualized by—
(A) Multiplying the gross receipts for
the short period by 12; and
(B) Dividing the product determined in
paragraph (h)(3)(iii)(A) of this section by
the number of months in the short period.
(iv)Definition of gross receipts.For
purposes of applying paragraph (h)(3)(i) of
this section, the termgross receiptsmeans
the taxpayer’s receipts for the taxable year
that are properly recognized under the tax-
2013–43 I.R.B.373October 21, 2013

payer’s methods of accounting used for
Federal income tax purposes for the tax-
able year. For this purpose, gross receipts
include total sales (net of returns and al-
lowances) and all amounts received for
services. In addition, gross receipts in-
clude any income from investments and
from incidental or outside sources. For ex-
ample, gross receipts include interest (in-
cluding original issue discount and tax-ex-
empt interest within the meaning of section
103), dividends, rents, royalties, and annu-
ities, regardless of whether such amounts
are derived in the ordinary course of the
taxpayer’s trade of business. Gross re-
ceipts are not reduced by cost of goods
sold or by the cost of property sold if such
property is describedin section 1221(a)(1),
(3), (4), or (5). With respect to sales of
capital assets as defined in section 1221,
or sales of property described in section
1221(a)(2) (relating to property used in a
trade or business), gross receipts shall be
reduced by the taxpayer’s adjusted basis
in such property. Gross receipts do not
include the repayment of a loan or simi-
lar instrument (for example, a repayment
of the principal amount of a loan held by
a commercial lender) and, except to the
extent of gain recognized, do not include
gross receipts derived from a non-recog-
nition transaction, such as a section 1031
exchange. Finally, gross receipts do not
include amounts received by the taxpayer
with respect to sales tax or other similar
state and local taxes if, under the applica-
ble state or local law, the tax is legally im-
posed on the purchaser of the good or ser-
vice, and the taxpayer merely collects and
remits the tax to the taxing authority. If,
in contrast, the tax is imposed on the tax-
payer under the applicable law, then gross
receipts include the amounts received that
are allocable to the payment of such tax.
(4)Eligible building property. For pur-
poses of this section, the term,eligible
building propertyrefers to each unit of
property defined in paragraph (e)(2)(i)
(building), paragraph (e)(2)(iii)(A) (con-
dominium), paragraph (e)(2)(iv)(A) (co-
operative), or paragraph (e)(2)(v)(A)
(leased building or portion of building)
of this section, as applicable, that has an
unadjusted basis of $1,000,000 or less.
(5)Unadjusted basis—(i)Eligible
building property owned by taxpayer.For
purposes of this section, the unadjusted
basis of eligible building property owned
by the taxpayer means the basis as de-
termined under section 1012, or other
applicable sections ofChapter 1, including
subchapters O (relating to gain or loss on
dispositions of property), C (relating to
corporate distributions and adjustments),
K (relating to partners and partnerships),
and P (relating to capital gains and losses).
Unadjusted basis is determined without
regard to any adjustments described in
section 1016(a)(2) or (3) or to amounts for
which the taxpayer has elected to treat as
an expense (for example, under sections
179, 179B, or 179C).
(ii)Eligible building property leased to
the taxpayer. For purposes of this sec-
tion, the unadjusted basis of eligible build-
ing property leased to the taxpayer is the
total amount of (undiscounted) rent paid
or expected to be paid by the lessee under
the lease for the entire term of the lease,
including renewal periods if all the facts
and circumstances in existence during the
taxable year in which the lease is entered
indicate a reasonable expectancy of re-
newal. See §1.263(a)–4(f)(5)(ii) for the
factors significant in determining whether
there exists a reasonable expectancy of re-
newal.
(6)Time and manner of election.A
taxpayer makes the election described in
paragraph (h)(1) of this section by attach-
ing a statement to the taxpayer’s timely
filed original Federaltaxreturn(including
extensions) for the taxable year in which
amounts are paid for repairs, maintenance,
improvements, and similar activities per-
formed on the eligible building property
providing that such amounts qualify un-
der the safe harbor provided in paragraph
(h)(1) of this section. See §§301.9100–1
through 301.9100–3 of this chapter for the
provisions governing extensions of time to
make regulatory elections. The statement
must be titled, “Section 1.263(a)–3(h) Safe
Harbor Election for Small Taxpayers” and
include the taxpayer’s name, address, tax-
payer identification number, and a descrip-
tion of each eligible building property to
which the taxpayer is applying the elec-
tion. In the case of an S corporation or a
partnership,theelectionismadebytheS
corporation or by the partnership, and not
by the shareholders or partners. An elec-
tion may not be made through the filing
of an application for change in account-
ing method or, before obtaining the Com-
missioner’s consent to make a late elec-
tion, by filing an amended Federal tax re-
turn. A taxpayer may not revoke an elec-
tion made under this paragraph (h). The
time and manner of making the election
under this paragraph (h) may be modified
through guidance of general applicability
(see §§601.601(d)(2) and 601.602 of this
chapter).
(7)Treatment of safe harbor amounts.
Amounts paid by the taxpayer for repairs,
maintenance, improvements, and similar
activities to which the taxpayer properly
applies the safe harbor under paragraph
(h)(1) of this section and for which the
taxpayer properly makes the election un-
der paragraph (h)(6) of this section are not
treated as improvements under paragraph
(d) or (f) of this section and may be de-
ducted under §1.162–1 or §1.212–1, as ap-
plicable, in the taxable year these amounts
are paid, provided the amounts otherwise
qualify for a deduction under these sec-
tions.
(8)Safe harbor exceeded.Iftotal
amounts paid by a qualifying taxpayer
during the taxable year for repairs, main-
tenance, improvements, and similar ac-
tivities performed on an eligible building
property exceed the safe harbor limita-
tions specified in paragraph (h)(1) of this
section, then the safe harbor election is
not available for that eligible building
property and the taxpayer must apply the
general improvement rules under this sec-
tion to determine whether amounts are
for improvements to the unit of property,
including the safe harbor for routine main-
tenance under paragraph (i) of this section.
The taxpayer may also elect to apply thede
minimissafe harbor under §1.263(a)–1(f)
to amounts qualifying under that safe har-
bor irrespective of the application of this
paragraph (h).
(9)Modification of safe harbor
amounts. The amount limitations pro-
vided in paragraphs (h)(1)(i), (h)(1)(ii),
and (h)(3) of this section may be modified
through published guidance in theFed-
eral Registeror in the Internal Revenue
Bulletin (see §601.601(d)(2)(ii)(b)ofthis
chapter).
(10)Examples. The following exam-
ples illustrate the rules of this paragraph
(h). Assume that §1.212–1 does not apply
to the amounts paid.
Example 1.Safe harbor for small taxpayers ap-
plicable
. A is a qualifying taxpayer under paragraph
(h)(3) of this section. A owns an office building
October 21, 20133742013–43 I.R.B.

in which A provides consulting services. In Year
1, A’s building has an unadjusted basis of $750,000
as determined under paragraph (h)(5)(i) of this sec-
tion. In Year 1, A pays $5,500 for repairs, main-
tenance, improvements and similar activities to the
office building. Because A’s building unit of prop-
erty has an unadjusted basis of $1,000,000 or less,
A’s building constitutes eligible building property un-
der paragraph (h)(4) of this section. The aggregate
amountpaidbyAduringYear1forrepairs,main-
tenance, improvements and similar activities on this
eligible building property does not exceed the lesser
of $15,000 (2 percent of the building’s unadjusted ba-
sis of $750,000) or $10,000. Therefore, under para-
graph (h)(1) of this section, A may elect to not apply
the capitalization rule of paragraph (d) of this sec-
tion to the amounts paid for repair, maintenance, im-
provements, or similar activities on the office build-
inginYear1.IfAproperlymakestheelectionunder
paragraph (h)(6) of this section for the office build-
ing and the amounts otherwise constitute deductible
ordinary and necessary expenses incurredin carrying
on a trade or business, A may deduct these amounts
under §1.162–1 in Year 1.
Example 2.Safe harbor for small taxpayers in-
applicable
. Assume the same facts as inExample 1,
except that A pays $10,500 for repairs, maintenance,
improvements, and similar activities performed on
its office building in Year 1. Because this amount
exceeds $10,000, the lesser of the two limitations
provided in paragraph (h)(1) of this section, A may
not apply the safe harbor for small taxpayers under
paragraph (h)(1) of this section to the total amounts
paid for repairs, maintenance, improvements, and
similar activities performed on the building. There-
fore, A must apply the general improvement rules
under this section to determine which of the aggre-
gate amounts paid are for improvements and must be
capitalized under paragraph (d) of this section and
which of the amounts are for repair and maintenance
under §1.162–4.
Example 3.Safe harbor applied build-
ing-by-building
. (i) B is a qualifying taxpayer under
paragraph (h)(3) of this section. B owns two rental
properties, Building M and Building N. Building
M and Building N are both multi-family residential
buildings. In Year 1, each property has an unad-
justed basis of $300,000 under paragraph (h)(5) of
this section. Because Building M and Building N
each have an unadjusted basis of $1,000,000 or less,
Building M and Building N each constitute eligible
building property in Year 1 under paragraph (h)(4)
of this section. In Year 1, B pays $5,000 for repairs,
maintenance, improvements, and similar activities
performedonBuildingM.InYear1,Balsopays
$7,000 for repairs, maintenance, improvements, and
similar activities performed on Building N.
(ii) The total amount paid by B during Year 1 for
repairs, maintenance, improvements and similar ac-
tivities on Building M ($5,000) does not exceed the
lesser of $6,000 (2 percent of the building’s unad-
justed basis of $300,000) or $10,000. Therefore, un-
der paragraph (h)(1) of this section, for Year 1, B may
elect to not apply the capitalization rule under para-
graph (d) of this section to the amounts it paid for re-
pairs, maintenance, improvements, and similar activ-
ities on Building M. If B properly makes the election
under paragraph (h)(6) of this section for Building M
and the amounts otherwise constitute deductible ordi-
nary and necessary expenses incurred in carrying on
B’s trade or business, B may deduct these amounts
under §1.162–1.
(iii) The total amount paid by B during Year 1
for repairs, maintenance, improvements and similar
activities on Building N ($7,000) exceeds $6,000
(2 percent of the building’s unadjusted basis of
$300,000), the lesser of the two limitations provided
under paragraph (h)(1) of this section. Therefore, B
may not apply the safe harbor under paragraph (h)(1)
of this section to the total amounts paid for repairs,
maintenance, improvements, and similar activities
performed on Building N. Instead, B must apply
the general improvement rules under this section
to determine which of the total amounts paid for
work performed on Building N are for improvements
and must be capitalized under paragraph (d) of this
section and which amounts are for repair and main-
tenance under §1.162–4.
Example 4.Safe harbor applied to leased build-
ing property
. C is a qualifying taxpayer under para-
graph (h)(3) of this section. C is the lessee of a build-
ing in which C operates a retail store. The lease is
a triple-net lease, and the lease term is 20 years, in-
cluding reasonably expected renewals. C pays $4,000
per month in rent. In Year 1, C pays $7,000 for re-
pairs, maintenance, improvements, and similar ac-
tivities performed on the building. Under paragraph
(h)(5)(ii) of this section, the unadjusted basis of C’s
leased unit of property is $960,000 ($4,000 monthly
rent x 12 months x 20 years). Because C’s leased
building has an unadjusted basis of $1,000,000 or
less, the building is eligible building property for Year
1 under paragraph (h)(4) of this section. The total
amountpaidbyCduringYear1forrepairs,main-
tenance, improvements, and similar activities on the
leased building ($7,000) does not exceed the lesser of
$19,200 (2 percent of the building’s unadjusted ba-
sis of $960,000) or $10,000. Therefore, under para-
graph (h)(1) of this section, for Year 1, C may elect
to not apply the capitalization rule under paragraph
(d) of this section to the amounts it paid for repairs,
maintenance, improvements, and similar activities on
the leased building. If C properly makes the elec-
tionunderparagraph(h)(6)ofthissectionforthe
leased building and the amounts otherwise constitute
deductible ordinary and necessary expenses incurred
in carrying on C’s trade or business, C may deduct
these amounts under §1.162–1.
(i)Safe harbor for routine mainte-
nance on property—(1)In general.An
amount paid for routine maintenance (as
defined in paragraph (i)(1)(i) or (i)(1)(ii)
of this section, as applicable) on a unit of
tangible property, orin the case of a build-
ing, on any of the properties designated
in paragraphs (e)(2)(ii), (e)(2)(iii)(B),
(e)(2)(iv)(B), or paragraph (e)(2)(v)(B) of
this section, is deemed not to improve that
unit of property.
(i)Routine maintenance for buildings.
Routine maintenance for a building unit
of property is the recurring activities that
a taxpayer expects to perform as a result
of the taxpayer’s use of any of the prop-
erties designated in paragraphs (e)(2)(ii),
(e)(2)(iii)(B), (e)(2)(iv)(B), or (e)(2)(v)(B)
of this section to keep the building struc-
ture or each building system in its or-
dinarily efficient operating condition.
Routine maintenance activities include,
for example, the inspection, cleaning, and
testing of the building structure or each
building system, and the replacement of
damaged or worn parts with comparable
and commercially available replacement
parts. Routine maintenance may be per-
formed any time during the useful life
of the building structure or building sys-
tems. However, the activities are routine
only if the taxpayer reasonably expects
to perform the activities more than once
during the 10-year period beginning at the
time the building structure or the building
system upon which the routine mainte-
nance is performed is placed in service
by the taxpayer. A taxpayer’s expectation
will not be deemed unreasonable merely
because the taxpayer does not actually
perform the maintenance a second time
during the 10-year period, provided that
the taxpayer can otherwise substantiate
that its expectation was reasonable at the
time the property was placed in service.
Factors to be considered in determin-
ing whether maintenance is routine and
whether a taxpayer’s expectation is rea-
sonable include the recurring nature of the
activity, industry practice, manufacturers’
recommendations, and the taxpayer’s ex-
perience with similar or identical property.
With respect to a taxpayer that is a lessor
of a building or a part of the building,
the taxpayer’s use of the building unit of
property includes the lessee’s use of its
unit of property.
(ii)Routine maintenance for property
other than buildings. Routine maintenance
for property other than buildings is the
recurring activities that a taxpayer expects
to perform as a result of the taxpayer’s
use of the unit of property to keep the
unit of property in its ordinarily efficient
operating condition. Routine maintenance
activities include, for example, the inspec-
tion, cleaning, and testing of the unit of
property, and the replacement of damaged
or worn parts of the unit of property with
comparable and commercially available
replacement parts. Routine maintenance
may be performed any time during the use-
ful life of the unit of property. However,
the activities are routine only if, at the time
the unit of property is placed in service
2013–43 I.R.B.375October 21, 2013

by the taxpayer, the taxpayer reasonably
expects to perform the activities more
than once during the class life (as defined
in paragraph (i)(4) of this section) of the
unit of property. A taxpayer’s expectation
will not be deemed unreasonable merely
because the taxpayer does not actually
perform the maintenance a second time
during the class life of the unit of property,
provided that the taxpayer can otherwise
substantiate that its expectation was rea-
sonable at the time the property was placed
in service. Factors to be considered in de-
termining whether maintenance is routine
and whether the taxpayer’s expectation is
reasonable include the recurring nature of
the activity, industry practice, manufactur-
ers’ recommendations, and the taxpayer’s
experience with similaroridenticalprop-
erty. With respect to a taxpayer that is a
lessor of a unit of property, the taxpayer’s
use of the unit of property includes the
lessee’s use of the unit of property.
(2)Rotable and temporary spare parts.
Except as provided in paragraph (i)(3) of
this section, for purposes of paragraph
(i)(1)(ii) of this section, amounts paid for
routine maintenanceinclude routine main-
tenance performed on (and with regard to)
rotable and temporary spare parts.
(3)Exceptions. Routine maintenance
does not include the following:
(i) Amounts paid for a betterment to a
unit of property under paragraph (j) of this
section;
(ii) Amounts paid for the replacement
of a component of a unit of property for
which the taxpayer has properly deducted
a loss for that component (other than a ca-
sualty loss under §1.165–7) (see paragraph
(k)(1)(i) of this section);
(iii) Amounts paid for the replacement
of a component of a unit of property for
which the taxpayer has properly taken into
account the adjusted basis of the compo-
nent in realizing gain or loss resulting from
the sale or exchange of the component (see
paragraph (k)(1)(ii) of this section);
(iv) Amounts paid for the restoration of
damage to a unit of property for which the
taxpayer is required to take a basis adjust-
ment as a result of a casualty loss under
section 165, or relating to a casualty event
described in section 165,subject to the lim-
itation in paragraph (k)(4) of this section
(see paragraph (k)(1)(iii) of this section);
(v) Amounts paid to return a unit of
property to its ordinarily efficient operat-
ing condition, if the property has deterio-
rated to a state of disrepair and is no longer
functional for its intended use (see para-
graph (k)(1)(iv) of this section);
(vi) Amounts paid to adapt a unit of
property to a new or different use under
paragraph (l) of this section;
(vii) Amounts paid for repairs, mainte-
nance, or improvement of network assets
(as defined in paragraph (e)(3)(iii)(A) of
this section); or
(viii) Amounts paid for repairs, mainte-
nance, or improvement of rotable and tem-
porary spare parts to which the taxpayer
applies the optional method of accounting
for rotable and temporary spare parts un-
der §1.162–3(e).
(4)Class life. The class life of a unit
of property is the recovery period pre-
scribed for the property under sections
168(g)(2) and (3) for purposes of the alter-
native depreciation system, regardless of
whether the property is depreciated under
section 168(g). For purposes of determin-
ing class life under this section, section
168(g)(3)(A) (relating to tax-exempt use
property subject to lease) does not ap-
ply. If the unit of property is comprised
of components with different class lives,
then the class life of the unit of property is
deemed to be the same as the component
with the longest class life.
(5)Coordination with section 263A.
Amounts paid for routine maintenance
under this paragraph (i) may be subject
to capitalization under section 263A if
these amounts comprise the direct or al-
locable indirect costs of other property
produced by the taxpayer or property
acquired for resale. See, for example,
§1.263A–1(e)(3)(ii)(O) requiring tax-
payers to capitalize the cost of repairing
equipment or facilities allocable to prop-
erty produced or property acquired for
resale.
(6)Examples. The following examples
illustrate the application of this paragraph
(i) and, unless otherwise stated, do not ad-
dress the treatment under other provisions
of the Code (for example, section 263A).
In addition, unless otherwise stated, as-
sume that the taxpayer has not applied
the optional method of accounting for
rotable and temporary spare parts under
§1.162–3(e).
Example 1.Routine maintenance on component.
(i) A is a commercial airline engaged in the business
of transporting passengers and freight throughout the
United States and abroad. To conduct its business, A
owns or leases various types of aircraft. As a con-
dition of maintaining its airworthiness certification
for these aircraft, A is required by the Federal Avia-
tion Administration (FAA) to establish and adhere to
a continuous maintenance program for each aircraft
within its fleet. These programs, which are designed
by A and the aircraft’s manufacturer and approved by
the FAA, are incorporated into each aircraft’s main-
tenance manual. The maintenance manuals require a
variety of periodic maintenance visits at various in-
tervals. One type of maintenance visit is an engine
shop visit (ESV), which A expects to perform on its
aircraft engines approximately every 4 years to keep
its aircraft in its ordinarily efficient operating condi-
tion. In Year 1, A purchased a new aircraft, which
included four new engines attached to the airframe.
The four aircraft engines acquired with the aircraft
are not materials or supplies under §1.162–3(c)(1)(i)
because they are acquired as part of a single unit of
property, the aircraft. In Year 5, A performs its first
ESV on the aircraft engines. The ESV includes disas-
sembly, cleaning, inspection, repair, replacement, re-
assembly, and testing of the engine and its component
parts. During the ESV, the engine is removed from
the aircraft and shipped to an outside vendor who per-
forms the ESV. If inspection or testing discloses a dis-
crepancy in a part’s conformity to the specifications
in A’s maintenance program,the part is repaired, or if
necessary, replaced with a comparable and commer-
cially available replacement part. After the ESVs, the
engines are returned to A to be reinstalled on another
aircraft or stored for laterinstallation. Assume that
the class life for A’s aircraft, including the engines, is
12 years. Assume that none of the exceptions set out
in paragraph (i)(3) of this section apply to the costs of
performing the ESVs.
(ii) Because the ESVs involve the recurring ac-
tivities that A expects to perform as a result of its use
of the aircraft to keep the aircraft in ordinarily effi-
cient operating condition and consist of maintenance
activities that A expects to perform more than once
during the 12 year class life of the aircraft, A’s ESVs
are within the routine maintenance safe harbor under
paragraph (i)(1)(ii) of this section. Accordingly, the
amounts paid for the ESVs are deemed not to improve
the aircraft and are not required to be capitalized un-
der paragraph (d) of this section.
Example 2.Routine maintenance after class life.
Assume the same facts as in
Example 1,exceptthat
in year 15 A pays amounts to perform an ESV on
one of the original aircraft engines after the end of
the class life of the aircraft. Because this ESV in-
volves the same routine maintenance activities that
were performed on aircraft engines in
Example 1,this
ESV also is within the routine maintenance safe har-
bor under paragraph (i)(1)(ii) of this section. Accord-
ingly, the amounts paid for this ESV, even though per-
formed after the class life of the aircraft, are deemed
not to improve the aircraft and are not required to be
capitalized under paragraph (d) of this section.
Example 3.Routine maintenance on rotable
spare parts
. (i) Assume the same facts as inExample
1
, except that in addition to the four engines pur-
chased as part of the aircraft, A separately purchases
four additional new engines that A intends to use in
its aircraft fleet to avoid operational downtime when
ESVs are required to be performed on the engines
previously installed on an aircraft. Later in Year
October 21, 20133762013–43 I.R.B.

1, A installs these four engines on an aircraft in its
fleet. In Year 5, A performs the first ESVs on these
four engines. Assume that these ESVs involve the
same routine maintenance activities that were per-
formed on the engines in
Example 1, and that none
of the exceptions set out in paragraph (i)(3) of this
section apply to these ESVs. After the ESVs were
performed, these engines were reinstalled on other
aircraft or stored for later installation.
(ii) The additional aircraft engines are rotable
spare parts because they were acquired separately
from the aircraft, they are removable from the air-
craft, and are repaired and reinstalled on other aircraft
or stored for later installation. See §1.162–3(c)(2)
(definition of rotable and temporary spare parts).
Assume the class life of an engine is the same as the
airframe, 12 years. Because the ESVs involve the
recurring activities that A expects to perform as a
result of its use of the engines to keep the engines in
ordinarily efficient operating condition, and consist
of maintenance activities that A expects to perform
more than once during the 12 year class life of the
engine, the ESVs fall within the routine maintenance
safe harbor under paragraph (i)(1)(ii) of this section.
Accordingly, the amounts paid for the ESVs for the
four additional engines are deemed not to improve
these engines and are not required to be capitalized
under paragraph (d) of this section. For the treat-
ment of amounts paid to acquire the engines, see
§1.162–3(a).
Example 4.Routine maintenance resulting from
prior owner’s use
. (i) In January, Year 1, B purchases
a used machine for use in its manufacturing opera-
tions. Assume that the machine is the unit of property
and has a class life of 10 years. B places the machine
in service in January, Year 1, and at that time, B ex-
pects to perform manufacturer recommended sched-
uled maintenance on the machine approximately ev-
ery three years. The scheduled maintenance includes
the cleaning and oiling of the machine, the inspec-
tion of parts for defects, and the replacement of mi-
nor items such as springs, bearings, and seals with
comparable and commercially available replacement
parts. At the time B purchased the machine, the ma-
chine was approaching the end of a three-year sched-
uled maintenance period. As a result, in February,
Year 1, B pays amounts to perform the manufacturer
recommended scheduled maintenance. Assume that
none of the exceptions set out in paragraph (i)(3) of
this section apply to the amounts paid for the sched-
uled maintenance.
(ii) The majority of B’s costs do not qualify un-
der the routine maintenance safe harbor in paragraph
(i)(1)(ii) of this section because the costs were in-
curred primarily as a result of the prior owner’s use
of the property and not B’s use. B acquired the ma-
chine just before it had received its three-year sched-
uled maintenance. Accordingly, the amounts paid
for the scheduled maintenance resulted from the prior
owner’s, and not B’s, use of the property and must be
capitalized if those amounts result in a betterment un-
der paragraph (i) of this section, including the amelio-
ration of a material condition or defect, or otherwise
result in an improvement under paragraph (d) of this
section.
Example 5.Routine maintenance resulting from
new owner’s use
. Assume the same facts as inEx-
ample 4
, except that after B pays amounts for the
maintenance in Year 1, B continues to operate the ma-
chine in its manufacturing business. In Year 4, B pays
amounts to perform the next scheduled manufacturer
recommended maintenance on the machine. Assume
that the scheduled maintenance activities performed
are the same as those performed in
Example 4and that
none of the exceptions set out in paragraph (i)(3) of
this section apply to the amounts paid for the sched-
uled maintenance. Because the scheduled mainte-
nance performed in Year 4 involves the recurring ac-
tivities that B performs as a result of its use of the
machine, keeps the machine in an ordinarily efficient
operating condition, and consists of maintenance ac-
tivities that B expects to perform more than once dur-
ing the 10-year class life of the machine, B’s sched-
uled maintenance costs are within the routine main-
tenance safe harbor under paragraph (i)(1)(ii) of this
section. Accordingly, the amounts paid for the sched-
uled maintenance in Year 4 are deemed not to im-
prove the machine and are not required to be capi-
talized under paragraph (d) of this section.
Example 6.Routine maintenance; replacement of
substantial structural part; coordination with section
263A
. C is in the business of producing commercial
products for sale. As part of the production process,
C places raw materials into lined containers in which
a chemical reaction is used to convert raw materials
into the finished product. The lining, which com-
prises 60 percent of the total physical structure of the
container, is a substantial structural part of the con-
tainer. Assume that each container, including its lin-
ing, is the unit of property and that a container has
a class life of 12 years. At the time that C placed
the container into service, C was aware that approx-
imately every three years, the container lining would
need to be replaced with comparable and commer-
cially available replacement materials. At the end of
three years, the container will continue to function,
but will become less efficient and the replacement of
the lining will be necessary to keep the container in
an ordinarily efficient operating condition. In Year 1,
C acquired 10 new containers and placed them into
service. In Year 4, Year 7, Year 9, and Year 12, C
pays amounts to replace the containers’ linings with
comparable and commercially available replacement
parts. Assume that none of the exceptions set out in
paragraph(i)(3)ofthissectionapplytotheamounts
paid for the replacement linings. Because the replace-
ment of the linings involves recurring activities that C
expects to perform as a result of its use of the contain-
ers to keep the containers in their ordinarily efficient
operating condition and consists of maintenance ac-
tivities that C expects to perform more than once dur-
ing the 12-year class life of the containers, C’s lining
replacement costs are withinthe routine maintenance
safe harbor under paragraph (i)(1)(ii) of this section.
Accordingly, the amounts that C paid for the replace-
ment of the container linings are deemed not to im-
prove the containers and are not required to be capi-
talized under paragraph (d) of this section. However,
the amounts paid to replace the lining may be subject
to capitalization under section 263A if the amounts
paid for this maintenance comprise the direct or al-
locable indirect costs of the property produced by C.
See §1.263A–1(e)(3)(ii)(O).
Example 7.Routine maintenance once during
class life
. D is a Class I railroad that owns a fleet of
freight cars. Assume that a freight car, including all
its components, is a unit of property and has a class
life of 14 years. At the time that D places a freight
car into service, D expects to perform cyclical recon-
ditioning to the car every 8 to 10 years to keep the
freight car in ordinarily efficient operating condition.
During this reconditioning, D pays amounts to dis-
assemble, inspect, and recondition or replace com-
ponents of the freight car with comparable and com-
mercially available replacement parts. Ten years af-
ter D places the freight car in service, D pays amounts
to perform a cyclical reconditioning on the car. Be-
cause D expects to perform the reconditioning only
once during the 14 year class life of the freight car, the
amounts D pays for the reconditioning do not qualify
for the routine maintenance safe harbor under para-
graph (i)(1)(ii) of this section. Accordingly, D must
capitalize the amounts paid for the reconditioning of
thefreightcariftheseamountsresultinanimprove-
ment under paragraph (d) of this section.
Example 8.Routine maintenance; reasonable ex-
pectation
.AssumethesamefactsasExample 7,ex-
cept in Year 1, D acquires and places in service sev-
eral refrigerated freight cars, which also have a class
life of 14 years. Because of the special requirements
of these cars, at the time they are placed in service,
D expects to perform a reconditioning of the refrig-
eration components of the freight car every 6 years
to keep the freight car in an ordinarily efficient op-
erating condition. During the reconditioning, D pays
amounts to disassemble, inspect, and recondition or
replace the refrigeration components of the freight
car with comparable and commercially available re-
placement parts. Assume that none of the exceptions
set out in paragraph (i)(3) of this section apply to the
amounts paid for the reconditioning of these freight
cars. In Year 6, D pays amounts to perform a recondi-
tioning on the refrigeration components on one of the
freight cars. However, because of changes in the fre-
quency that D utilizes this freight car, D does not per-
form the second reconditioning on the same freight
car until Year 15, after the end of the 14-year class life
of the car. Under paragraph (i)(1)(ii) of this section,
D’s reasonable expectation that it would perform the
reconditioning every 6 years will not be deemed un-
reasonable merely because D did not actually perform
the reconditioning a second time during the 14-year
class life, provided that D can substantiate that its ex-
pectation was reasonable at the time the property was
placed in service. If D can demonstrate that its ex-
pectation was reasonable in Year 1 using the factors
provided in paragraph (i)(1)(ii) of this section, then
the amounts paid by D to recondition the refriger-
ated freight car components in Year 6 and in Year 15
are within the routine maintenance safe harbor under
paragraph (i)(1)(ii) of this section.
Example 9.Routine maintenance on non-rotable
part
. E is a towboat operator that owns and leases a
fleet of towboats. Each towboat is equipped with two
diesel-powered engines. Assume that each towboat,
including its engines, is the unit of property and that
a towboat has a class life of 18 years. At the time
that E places its towboats into service, E is aware
that approximately every three to four years E will
need to perform scheduled maintenance on the two
towboat engines to keep the engines in their ordinar-
ily efficient operating condition. This maintenance
is completed while the engines are attached to the
towboat and involves the cleaning and inspecting
of the engines to determine which parts are within
acceptable operating tolerances and can continue to
be used, which parts must be reconditioned to be
2013–43 I.R.B.377October 21, 2013

brought back to acceptable tolerances, and which
parts must be replaced. Engine parts replaced during
these procedures are replaced with comparable and
commercially available replacement parts. Assume
the towboat engines are not rotable spare parts under
§1.162–3(c)(2). In Year 1, E acquired a new towboat,
including its two engines, and placed the towboat
into service. In Year 5, E pays amounts to perform
scheduled maintenance on both engines in the tow-
boat. Assume that none of the exceptions set out in
paragraph (i)(3) of this section apply to the scheduled
maintenance costs. Because the scheduled mainte-
nance involves recurring activities that E expects to
perform more than once during the 18-year class life
of the towboat, the maintenance results from E’s use
of the towboat, and the maintenance is performed to
keep the towboat in an ordinarily efficient operating
condition, the scheduled maintenance on E’s towboat
is within the routine maintenance safe harbor under
paragraph (i)(1)(ii) of this section. Accordingly, the
amounts paid for the scheduled maintenance to its
towboat engines in Year 5 are deemed not to improve
the towboat and are not required to be capitalized
under paragraph (d) of this section.
Example 10.Routine maintenance with related
betterments
. Assume the same facts asExample 9,
except that in Year 9 E’s towboat engines are due for
another scheduled maintenance visit. At this time, E
decides to upgrade the engines to increase their horse-
power and propulsion, which would permit the tow-
boats to tow heavier loads. Accordingly, in Year 9,
E pays amounts to perform many of the same activ-
ities that it would perform during the typical sched-
uled maintenance activities such as cleaning, inspect-
ing, reconditioning, and replacing minor parts, but at
the same time, E incurs costs to upgrade certain en-
gine parts to increase the towing capacity of the boats
in excess of the capacity of the boats when E placed
them in service. In combination with the replace-
ment of parts with new and upgraded parts, the sched-
uled maintenance must be completed to perform the
horsepower and propulsion upgrade. Thus, the work
done on the engines encompasses more than the re-
curring activities that E expected to perform as a re-
sult of its use of the towboats and did more than keep
the towboat in its ordinarily efficient operating con-
dition. Rather under paragraph (j) of this section, the
amounts paid to increase the horsepower and propul-
sion of the engines are for a betterment to the tow-
boat, and such amounts are excepted from the routine
maintenance safe harbor under paragraph (i)(3)(i) of
this section. In addition, under paragraph (g)(1)(i) of
this section, the scheduled maintenance procedures
directly benefit the upgrades. Therefore, the amounts
that E paid in Year 9 for the maintenance and upgrade
of the engines do not qualify for the routine mainte-
nance safe harbor described under paragraph (i)(1)(ii)
of this section. Rather, E must capitalize the amounts
paid for maintenance and upgrades of the engines as
an improvement to the towboats under paragraph (d)
of this section.
Example 11.Routine maintenance with unrelated
improvements
. Assume the same facts asExample 9,
except in Year 5, in addition to paying amounts to
perform the scheduled engine maintenance on both
engines, E also incurs costs to upgrade the communi-
cations and navigation systems in the pilot house of
the towboat with new state-of-the-art systems. As-
sume the amounts paid to upgrade the communica-
tions and navigation systems are for betterments un-
der paragraph (j) of this section, and therefore result
in an improvement to the towboat under paragraph
(d) of this section. In contrast with
Example 9,the
amounts paid for the scheduled maintenance on E’s
towboat engines are not otherwise related to the up-
grades to the navigation systems. Because the sched-
uled maintenance on the towboat engines does not di-
rectly benefit and is not incurred by reason of the up-
grades to the communication and navigation systems,
the amounts paid for the scheduled engine mainte-
nance are not a direct or indirect cost of the improve-
ment under paragraph (g)(1)(i) of this section. Ac-
cordingly, the amounts paid for the scheduled main-
tenance to its towboat engines in Year 5 are routine
maintenance deemed not toimprove the towboat and
are not required to be capitalized under paragraph (d)
of this section.
Example 12.Exceptions to routine maintenance.
F owns and operates a farming and cattle ranch with
an irrigation system that provides water for crops.
Assume that each canal in the irrigation system is a
single unit of property and has a class life of 20 years.
At the time F placed the canals into service, F ex-
pected to have to perform major maintenance on the
canals every three years to keep the canals in their
ordinarily efficient operating condition. This mainte-
nance includes draining the canals, and then cleaning,
inspecting, repairing, and reconditioning or replacing
parts of the canal with comparable and commercially
available replacement parts. F placed the canals into
service in Year 1 and did not perform any mainte-
nance on the canals until Year 6. At that time, the
canals had fallen into a state of disrepair and no longer
functioned for irrigation. In Year 6, F pays amounts to
drain the canals and do extensive cleaning, repairing,
reconditioning, and replacing parts of the canals with
comparable and commercially available replacement
parts. Although the work performed on F’s canals
was similar to the activities that F expected to per-
form, but did not perform, every three years, the costs
of these activities do not fall within the routine main-
tenance safe harbor. Specifically, under paragraph
(i)(3)(v) of this section, routine maintenance does not
include activities that return a unit of property to its
former ordinarily efficient operating condition if the
property has deteriorated to a state of disrepair and
is no longer functional for its intended use. Accord-
ingly, amounts that F pays for work performed on the
canals in Year 6 must be capitalized if they result in
improvements under paragraph (d) of this section (for
example, restorations under paragraph (k) of this sec-
tion).
Example 13.Routine maintenance on a building;
escalator system
. In Year 1, G acquires a large retail
mall in which it leases space to retailers. The mall
contains an escalator system with 40 escalators,
which includes landing platforms, trusses, tracks,
steps, handrails, and safety brushes. In Year 1, when
G placed its building into service, G reasonably ex-
pected that it would need toreplace the handrails on
the escalators approximately every four years to keep
the escalator system in its ordinarily efficient operat-
ing condition. After a routine inspection and test of
the escalator system in Year 4, G determines that the
handrails need to be replaced and pays an amount
to replace the handrails with comparable and com-
mercially available handrails. The escalator system,
including the handrails, is a building system under
paragraph (e)(2)(ii)(B)(
4)ofthissection. Assume
that none of the exceptions in paragraph (i)(3) of this
section apply to the scheduled maintenance costs.
Because the replacement of the handrails involves
recurring activities that Gexpects to perform as a
result of its use of the escalator system to keep the
escalator system in an ordinarily efficient operating
condition, and G reasonably expects to perform these
activities more than once during the 10-year period
beginning at the time building system was placed
in service, the amounts paid by G for the handrail
replacements are withinthe routine maintenance
safe harbor under paragraph (i)(1)(i) of this section.
Accordingly, the amounts paid for the replacement
of the handrails in Year 4 are deemed not to improve
the building unit of property and are not required to
be capitalized under paragraph (d) of this section.
Example 14.Not routine maintenance; escala-
tor system
. Assume the same facts as inExample 13,
except that in Year 9, G pays amounts to replace the
steps of the escalators. In Year 1, when G placed its
building into service, G reasonably expected that ap-
proximately every 18 to 20 years G would need to re-
place the steps to keep the escalator system in its ordi-
narily efficient operating condition. Because the re-
placement does not involve recurring activities that G
expects to perform more than once during the 10-year
period beginning at the time the building structure or
the building system was placed in service, the costs
of these activities do not fall within the routine main-
tenance safe harbor. Accordingly, amounts that G
pays to replace the steps in Year 9 must be capitalized
if they result in improvements under paragraph (d)
of this section (for example, restorations under para-
graph (k) of this section).
Example 15.Routine maintenance on building;
reasonable expectation
. In Year 1, H acquires a new
office building, which it uses to provide services.
The building contains an HVAC system, which is a
building system under paragraph (e)(2)(ii)(B)(
1)of
this section. In Year 1, when H placed its building
into service, H reasonably expected that every four
years H would need to pay an outside contractor to
perform detailed testing, monitoring, and preventa-
tive maintenance on its HVAC system to keep the
HVAC system in its ordinarily efficient operating
condition. This scheduled maintenance includes dis-
assembly, cleaning, inspection, repair, replacement,
reassembly, and testing of the HVAC system and
many of its component parts. If inspection or testing
discloses a problem with any component, the part is
repaired, or if necessary, replaced with a comparable
and commercially available replacement part. The
scheduled maintenance at these intervals is recom-
mended by the manufacturer of the HVAC system
and is routinely performed on similar systems in sim-
ilar buildings. Assume that none of the exceptions in
paragraph (i)(3) of this section apply to the amounts
paid for the maintenance on the HVAC system. In
Year 4, H pays amounts to a contractor to perform
the scheduled maintenance. However, H does not
perform this scheduled maintenance on its building
again until Year 11. Under paragraph (i)(1)(i) of
this section, H’s reasonable expectation that it would
perform the maintenance every 4 years will not be
deemed unreasonable merely because H did not ac-
tually perform the maintenance a second time during
the 10-year period, provided that H can substantiate
that its expectation was reasonable at the time the
October 21, 20133782013–43 I.R.B.

property was placed in service. If H can demonstrate
that its expectation was reasonable in Year 1 using
the other factors considered in paragraph (i)(1)(i),
then the amounts H paid for the maintenance of the
HVAC system in Year 4 and in Year 11 are within
the routine maintenance safe harbor under paragraph
(i)(1)(i) of this section.
(j)Capitalization of betterments—(1)
In general.A taxpayer must capitalize as
an improvement an amount paid for a bet-
terment to a unit of property. An amount is
paid for a betterment to a unit of property
only if it—
(i) Ameliorates a material condition or
defect that either existed prior to the tax-
payer’s acquisition of the unit of property
or arose during the production of the unit
of property, whether or not the taxpayer
was aware of the condition or defect at the
time of acquisition or production;
(ii) Is for a material addition, includ-
ing a physical enlargement, expansion, ex-
tension, or addition of a major component
(as defined in paragraph (k)(6) of this sec-
tion) to the unit of property or a material in-
crease in the capacity, including additional
cubic or linear space,of the unit of prop-
erty; or
(iii) Is reasonably expected to materi-
ally increase the productivity, efficiency,
strength, quality, or output of the unit of
property.
(2)Application of betterment rules—(i)
In general. The applicability of each quan-
titative and qualitative factor provided in
paragraphs (j)(1)(ii) and (j)(1)(iii) of this
section to a particular unit of property de-
pends on the nature of the unit of property.
For example, if an addition or an increase
in a particular factor cannot be measured in
the context of a specific type of property,
this factor is not relevant in the determina-
tion of whether an amount has been paid
for a betterment to the unit of property.
(ii)Application of betterment rules to
buildings. Anamountispaidtoimprove
a building if it is paid for a betterment,
as defined under paragraph (j)(1) of this
section, to a property specified under
paragraph (e)(2)(ii) (building), paragraph
(e)(2)(iii)(B) (condominium), paragraph
(e)(2)(iv)(B) (cooperative), or paragraph
(e)(2)(v)(B) (leased building or leased
portion of building) of this section. For
example, an amount is paid to improve a
building if it is paid for an increase in the
efficiency of the building structure or any
one of its building systems (for example,
the HVAC system).
(iii)Unavailability of replacement
parts. If a taxpayer replaces a part of a
unit of property that cannot reasonably
be replaced with the same type of part
(for example, because of technological
advancements or product enhancements),
the replacement of the part with an im-
proved, but comparable, part does not, by
itself, result in a betterment to the unit of
property.
(iv)Appropriate comparison—(A)In
general. In cases in which an expenditure
is necessitated by normal wear and tear
or damage to the unit of property that oc-
curred during the taxpayer’s use of the unit
of property, the determination of whether
an expenditure is for the betterment of the
unit of property is made by comparing
the condition of the property immediately
after the expenditure with the condition of
the property immediately prior to the cir-
cumstances necessitating the expenditure.
(B)Normal wear and tear.Iftheex-
penditure is made to correct the effects of
normal wear and tear to the unit of prop-
erty that occurred during the taxpayer’s
use of the unit of property, the condition
of the property immediately prior to the
circumstances necessitating the expendi-
ture is the condition of the property af-
ter the last time the taxpayer corrected the
effects of normal wear and tear (whether
the amounts paid were for maintenance or
improvements) or, if the taxpayer has not
previously corrected the effects of normal
wear and tear, the condition of the property
when placed in service by the taxpayer.
(C)Damage to property. If the expen-
diture is made to correct damage to a unit
of property that occurred during the tax-
payer’s use of the unit of property, the con-
dition of the property immediately prior to
the circumstances necessitating the expen-
diture is the condition of the property im-
mediately prior to damage.
(3)Examples. The following examples
illustrate the application of this paragraph
(j) only and do not address whether capi-
talization is required under another provi-
sion of this section or another provision of
the Internal Revenue Code (for example,
section 263A). Unless otherwise provided,
assume that the appropriate comparison in
paragraph (j)(2)(iv) of this section is not
applicable under the facts.
Example 1.Amelioration of pre-existing material
condition or defect
. In Year 1, A purchases a store
located on a parcel of land that contains underground
gasoline storage tanks left by prior occupants. As-
sume that the parcel of land is the unit of property.
The tanks had leaked prior to A’s purchase, causing
soil contamination. A is not aware of the contamina-
tion at the time of purchase. In Year 2, A discovers the
contamination and incurs costs to remediate the soil.
The remediation costs are for a betterment to the land
under paragraph (j)(1)(i) of this section because A in-
curred the costs to ameliorate a material condition or
defect that existed prior to A’s acquisition of the land.
Example 2.Not amelioration of pre-existing con-
dition or defect
. B owns an office building that was
constructed with insulation that contained asbestos.
The health dangers of asbestos were not widely
known when the building was constructed. Several
years after B places the building into service, B
determines that certain areas of asbestos-containing
insulation have begun to deteriorate and could even-
tually pose a health risk to employees. Therefore, B
pays an amount to remove the asbestos-containing
insulation from the building structure and replace it
with new insulation that is safer to employees, but
no more efficient or effective than the asbestos insu-
lation. Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a building
unit of property if the amount is paid for a betterment
to the building structure or any building system.
Although the asbestos is determined to be unsafe
under certain circumstances, the presence of asbestos
insulation in a building, by itself, is not a preexisting
material condition or defect of the building structure
under paragraph (j)(1)(i) of this section. In addition,
the removal and replacement of the asbestos is not
for a material addition to the building structure or
a material increase in the capacity of the building
structure under paragraphs (j)(1)(ii) and (j)(2)(iv)
of this section as compared to the condition of the
property prior to the deterioration of the insulation.
Similarly, the removal and replacement of asbestos
is not reasonably expected to materially increase the
productivity, efficiency, strength, quality, or output
of the building structure under paragraphs (j)(1)(iii)
and (j)(2)(iv) of this section as compared to the con-
dition of the property prior to the deterioration of the
insulation. Therefore, theamountpaidtoremoveand
replace the asbestos insulation is not for a betterment
to the building structure or an improvement to the
building under paragraph (j) of this section.
Example 3.Not amelioration of pre-existing ma-
terial condition or defect
. (i) In January, Year 1,
C purchased a used machine for use in its manu-
facturing operations. Assume that the machine is a
unit of property and has a class life of 10 years. C
placed the machine in service in January, Year 1 and
at that time expected to perform manufacturer recom-
mended scheduled maintenance on the machine ev-
ery three years. The scheduled maintenance includes
cleaning and oiling the machine, inspecting parts for
defects, and replacing minor items, such as springs,
bearings, and seals, with comparable and commer-
cially available replacement parts. The scheduled
maintenance does not include any material additions
or materially increase the capacity, productivity, effi-
ciency, strength, quality, or output of the machine. At
the time C purchased the machine, it was approaching
the end of a three-year scheduled maintenance period.
As a result, in February, Year 1, C pays an amount
to perform the manufacturer recommended scheduled
2013–43 I.R.B.379October 21, 2013

maintenance to keep the machine in its ordinarily ef-
ficient operating condition.
(ii) The amount that C pays does not qualify un-
der the routine maintenance safe harbor in paragraph
(i) of this section, because the cost primarily results
from the prior owner’s use of the property and not
the taxpayer’s use. C acquired the machine just be-
fore it had received its three-year scheduled mainte-
nance. Accordingly, the amount that C pays for the
scheduled maintenance results from the prior owner’s
use of the property and ameliorates conditions or de-
fects that existed prior to C’s ownership of the ma-
chine. Nevertheless, considering the purpose and mi-
nor nature of the work performed, this amount does
not ameliorate a material condition or defect in the
machine under paragraph (j)(1)(i) of this section, is
not for a material addition to or increase in capacity of
the machine under paragraph (j)(1)(ii) of this section,
and is not reasonably expected to materially increase
the productivity, efficiency, strength, quality, or out-
put of the machine under paragraph (j)(1)(iii) of this
section. Therefore, C is not required to capitalize the
amount paid for the scheduled maintenance as a bet-
terment to the unit of property under this paragraph
(j).
Example 4.Not amelioration of pre-existing ma-
terial condition or defect
. D purchases a used ice
resurfacing machine for use in the operation of its
ice skating rink. To comply with local regulations,
D is required to routinely monitor the air quality in
the ice skating rink. One week after D places the ma-
chine into service, during a routine air quality check,
D discovers that the operation of the machine is ad-
versely affecting the air quality in the skating rink.
As a result, D pays an amount to inspect and retune
the machine, which includes replacing minor com-
ponents of the engine that had worn out prior to D’s
acquisition of the machine. Assume the resurfacing
machine, including the engine, is the unit of property.
The routine maintenance safe harbor in paragraph (i)
of this section does not apply to the amounts paid, be-
cause the activities performed do not relate solely to
the taxpayer’s use of the machine. The amount that
D pays to inspect, retune, and replace minor com-
ponents of the ice resurfacing machine ameliorates a
condition or defect that existed prior to D’s acquisi-
tion of the equipment. Nevertheless, considering the
purpose and minor nature of the work performed, this
amount does not ameliorate a material condition or
defect in the machine under paragraph (j)(1)(i) of this
section. In addition, the amount is not paid for a ma-
terial addition to the machine or a material increase in
the capacity of the machineunder paragraph (j)(1)(ii)
of this section. Also, the activities are not reasonably
expected to materially increase the productivity, ef-
ficiency, strength, quality, or output of the machine
under paragraph (j)(1)(iii) of this section. Therefore,
D is not required to capitalize the amount paid to in-
spect, retune, and replace minor components of the
machine as a betterment under this paragraph (j).
Example 5.Amelioration of material condition
or defect
. (i) E acquires a building for use in its
business of providing assisted living services. Be-
fore and after the purchase, the building functions
as an assisted living facility. However, at the time
of the purchase, E is aware that the building is in a
condition that is below the standards that E requires
for facilities used in its business. Immediately after
the acquisition and during the following two years,
while E continues to use the building as an assisted
living facility, E pays amounts for extensive repairs
and maintenance, and the acquisition of new prop-
erty to bring the facility into the high-quality condi-
tion for which E’s facilities are known. The work
on E’s building includes repairing damaged drywall,
repainting, re-wallpapering, replacing windows, re-
pairing and replacing doors, replacing and regrout-
ing tile, repairing millwork, and repairing and replac-
ing roofing materials. The work also involves the re-
placement of section 1245 property, including win-
dow treatments, furniture, and cabinets. The work
that E performs affects only the building structure un-
der paragraph (e)(2)(ii)(A) of this section and does
not affect any of the building systems described in
paragraph (e)(2)(ii)(B) of this section. Assume that
each section 1245 property is a separate unit of prop-
erty.
(ii) Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a bet-
terment to the building structure or any building sys-
tem. Considering the purpose of the expenditure and
the effect of the expenditures on the building struc-
ture, the amounts that E paid for repairs and mainte-
nance to the building structure comprise a betterment
to the building structure under paragraph (j)(1)(i) of
this section because the amounts ameliorate mate-
rial conditions that existed prior to E’s acquisition of
the building. Therefore, E must treat the amounts
paid for the betterment to the building structure as
an improvement to the building and must capitalize
the amounts under paragraphs (j) and (d)(1) of this
section. Moreover, E is required to capitalize the
amounts paid to acquire and install each section 1245
property, including each window treatment, each item
of furniture, and each cabinet, in accordance with
§1.263(a)–2(d)(1).
Example 6.Not a betterment; building refresh.
(i) F owns a nationwide chain of retail stores that sell
a wide variety of items. To maintain the appearance
and functionality of its store buildings after several
years of wear, F periodically pays amounts to refresh
the look and layout of its stores. The work that F per-
forms during a refresh consists of cosmetic and lay-
out changes to the store’s interiors and general repairs
and maintenance to the store building to modernize
the store buildings and reorganize the merchandise
displays. The work to each store consists of replac-
ing and reconfiguring display tables and racks to pro-
vide better exposure of the merchandise, making cor-
responding lighting relocations and flooring repairs,
moving one wall to accommodate the reconfiguration
of tables and racks, patching holes in walls, repainting
the interior structure with a new color scheme to coor-
dinate with new signage, replacing damaged ceiling
tiles, cleaning and repairing wood flooring through-
out the store building, and power washing building
exteriors. The display tables and the racks all consti-
tute section 1245 property. F pays amounts to refresh
50 stores during the taxable year. Assume that each
section 1245 property within each store is a separate
unit of property. Finally, assume that the work does
not ameliorate any material conditions or defects that
existed when F acquired the store buildings or result
in any material additions to the store buildings.
(ii) Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a bet-
terment to the building structure or any building sys-
tem. Considering the facts and circumstances includ-
ing the purpose of the expenditure, the physical na-
ture of the work performed, and the effect of the ex-
penditure on the buildings’ structure and systems, the
amounts paid for the refresh of each building are not
for any material additionsto, or material increases
in the capacity of, the buildings’ structure or sys-
tems as compared with the condition of the structure
or systems after the previous refresh. Moreover, the
amounts paid are not reasonably expected to mate-
rially increase the productivity, efficiency, strength,
quality, or output of any building structure or sys-
tem under as compared to the condition of the struc-
tures or systems after the previous refresh. Rather, the
work performed keeps F’s store buildings’ structures
and buildings’ systems in their ordinarily efficient op-
erating condition. Therefore, F is not required to treat
the amounts paid for the refresh of its store buildings’
structures and buildings’ systems as betterments un-
der paragraphs (j)(1)(ii), (j)(1)(iii), and (j)(2)(iv) of
this section. However, F is required to capitalize the
amounts paid to acquire and install each section 1245
property in accordance with §1.263(a)–2(d)(1).
Example 7. Building refresh; limited improve-
ment
. (i) Assume the same facts asExample 6except,
in the course of the refresh to one of its store build-
ings, F also pays amounts to increase the building’s
storage space, add a second loading dock, and add a
second overhead door. Specifically, at the same time
F pays amounts to perform the refresh, F pays addi-
tional amounts to construct an addition to the back
of the store building, including adding a new over-
head door and loading dock to the building. The
work also involves upgrades to the electrical system
of the building, including the addition of a second
service box with increased amperage and new wiring
from the service box to provide lighting and power
throughout the new space. Although it is performed
at the same time, the construction of the additions
does not affect, and is not otherwise related to, the
refresh of the retail space.
(ii) Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a build-
ingunitofpropertyiftheamountispaidforabet-
terment to the building structure or any building sys-
tem. Under paragraph (j)(1)(ii) of this section, the
amounts paid by F to add the storage space, loading
dock, overhead door, and expand the electrical sys-
tem are for betterments to F’s building structure and
to the electrical system because they are for mate-
rial additions to, and a material increase in capacity
of, the structure and the electrical system of F’s store
building. Accordingly, F must treat the amounts paid
for these betterments as improvements to the building
unit of property and capitalize these amounts under
paragraphs (d)(1) and (j) of this section. However,
for the reasons discussed in
Example 6,Fisnotre-
quired to treat the amounts paid for the refresh of its
store building structure and systems as a betterments
under paragraph (j)(1) of this section. In addition, F
is not required under paragraph (g)(1) of this section
to capitalize the refresh costs described in
Example
6
because these costs do not directly benefit and are
not incurred by reason of the additions to the building
structure and electrical system. As in
Example 6,Fis
required to capitalize the amounts paid to acquire and
install each section 1245 property in accordance with
§1.263(a)–2(d)(1).

Example 8.Betterment; building remodel.(i)G
owns a large chain of retail stores that sell a variety
of items. G determines that due to changes in the re-
tail market, it can no longer compete in its current
store class and decides to upgrade its stores to offer
higher end products to a different type of customer.
To offer these products and attract different types of
customers, G must substantially remodel its stores.
Thus, G pays amounts to remodel its stores by per-
forming work on the buildings’ structures and sys-
tems as defined under paragraphs (e)(2)(ii)(A) and
(e)(2)(ii)(B) of this section. This work includes re-
placing large parts of the exterior walls with win-
dows, replacing the escalators with a monumental
staircase, adding a new glass enclosed elevator, re-
building the interior and exterior facades, replacing
vinyl floors with ceramic flooring, replacing ceiling
tiles with acoustical tiles, and removing and rebuild-
ing walls to move changing rooms and create spe-
cialty departments. The work also includes upgrades
to increase the capacity ofthe buildings’ electrical
system to accommodate the structural changes and
the addition of new section 1245 property, such as
new product information kiosks and point of sale sys-
tems. The work to the electrical system also involves
the installation of new more efficient and mood en-
hancing lighting fixtures. In addition, the work in-
cludes remodeling all bathrooms by replacing con-
tractor-grade plumbing fixtures with designer-grade
fixtures that conserve water and energy. Finally, G
also pays amounts to clean debris resulting from con-
struction during the remodel, patch holes in walls that
were made to upgrade the electrical system, repaint
existing walls with a new color scheme to match the
new interior construction, and to power wash build-
ing exteriors to enhance the new exterior facade.
(ii) Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a bet-
terment to the building structure or any building sys-
tem. Considering the facts and circumstances, in-
cluding the purpose of the expenditure, the physi-
cal nature of the work performed, and the effect of
the work on the buildings’ structures and buildings’
systems, the amounts that G pays for the remodel-
ing of its stores result in betterments to the build-
ings’ structures and several of its systems under para-
graph (j) of this section. Specifically, the amounts
paid to replace large parts of the exterior walls with
windows, replace the escalators with a monumen-
tal staircase, add a new elevator, rebuild the interior
and exterior facades, replace vinyl floors with ce-
ramic flooring, replace the ceiling tiles with acous-
tical tiles, and to remove and rebuild walls are for
material additions, that is the addition of major com-
ponents, to the building structure under paragraph
(j)(1)(ii) of this section and are reasonably expected
to increase the quality of the building structure un-
der paragraph (j)(1)(iii) of this section. Similarly,
the amounts paid to upgrade the electrical system
are to materially increase the capacity of the electri-
cal system under paragraph (j)(1)(ii) of this section
and are reasonably expected to increase the quality
of this system under paragraph (j)(1)(iii) of this sec-
tion. In addition, the amounts paid to remodel the
bathrooms with higher grade and more resource-ef-
ficient materials are reasonably expected to increase
the efficiency and quality of the plumbing system un-
der paragraph (j)(1)(iii) of this section. Finally, the
amounts paid to clean debris, patch and repaint exist-
ing walls with a new color scheme, and to power wash
building exteriors, while not betterments by them-
selves, directly benefitted and were incurred by rea-
son of the improvements to G’s store buildings’ struc-
tures and electrical systems under paragraph (g)(1)
of this section. Therefore, G must treat the amounts
paid for betterments to the store buildings’ structures
and systems, including the costs of cleaning, patch-
ing, repairing, and power washing the building, as
improvements to G’s buildings and must capitalize
these amounts under paragraphs (d)(1) and (j) of this
section. Moreover, G is required to capitalize the
amounts paid to acquire and install each section 1245
property in accordance with §1.263(a)–2(d)(1). For
the treatment of amounts paid to remove components
of property, see paragraph (g)(2) of this section.
Example 9.Not betterment; relocation and re-
installation of personal property.
In Year 1, H pur-
chases new cash registers for use in its retail store
located in leased space in a shopping mall. Assume
that each cash register is a unit of property as deter-
mined under paragraph (e)(3) of this section. In Year
1, H capitalizes the costs of acquiring and installing
the new cash registers under §1.263(a)–2(d)(1). In
Year 3, H’s lease expires, and H decides to relocate
its retail store to a different building. In addition to
various other costs, H pays $5,000 to move the cash
registers and $1,000 to reinstall them in the new store.
Thecashregistersareusedforthesamepurposeand
in the same manner that they were used in the former
location. The amounts that H pays to move and rein-
stall the cash registers into its new store do not result
in a betterment to the cash registers under paragraph
(j)ofthissection.
Example 10.Betterment; relocation and reinstal-
lation of equipment
. J operates a manufacturing facil-
ity in Building A, which contains various machines
that J uses in its manufacturing business. J decides
to expand part of its operations by relocating a ma-
chine to Building B to reconfigure the machine with
additional components. Assume that the machine is a
single unit of property under paragraph (e)(3) of this
section. J pays amounts to disassemble the machine,
to move the machine to the new location, and to re-
install the machine in a new configuration with addi-
tional components. Assume that the reinstallation, in-
cluding the reconfiguration and the addition of com-
ponents, is for an increase in capacity of the machine,
and therefore is for a betterment to the machine un-
der paragraph (j)(1)(ii) of this section. Accordingly,
J must capitalize the costs of reinstalling the machine
as an improvement to the machine under paragraphs
(j) and (d)(1) of this section. J is also required to cap-
italize the costs of disassembling and moving the ma-
chine to Building B because these costs directly ben-
efit and are incurred by reason of the improvement to
the machine under paragraph (g)(1) of this section.
Example 11. Betterment; regulatory requirement.
K owns a building that it uses in its business. In Year
1, City C passes an ordinance setting higher safety
standards for buildingsbecause of the hazardous
conditions caused by earthquakes. To comply with
the ordinance, K pays an amount to add expansion
bolts to its building structure. These bolts anchor
the wooden framing of K’s building to its cement
foundation, providing additional structural support
and resistance to seismic forces, making the building
more resistant to damage from lateral movement.
Under paragraphs (e)(2)(ii) and (j)(2)(ii) of this sec-
tion, an amount is paid to improve a building unit
of property if the amount is paid for a betterment
to the building structure or any building system.
The framing and foundation are part of the building
structure as defined in paragraph(e)(2)(ii)(A)ofthis
section. Prior to the ordinance, the old building was
in good condition but did not meet City C’s new
requirements for earthquake resistance. The amount
paid by K for the addition of the expansion bolts
met City C’s new requirement, but also materially
increased the strength of the building structure under
paragraph (j)(1)(iii) of this section. Therefore, K
must treat the amount paid to add the expansion bolts
as a betterment to the building structure and must
capitalize this amount as an improvement to building
under paragraphs (d)(1) and (j) of this section. City
C’s new requirement that K’s building meet certain
safety standards to continue to operate is not relevant
in determining whether the amount paid improved
the building. See paragraph (g)(4) of this section.
Example 12. Not a betterment; regulatory re-
quirement.
L owns a meat processing plant. After
operating the plant for many years, L discovers that
oil is seeping through the concrete walls of the plant.
Federal inspectors advise L that it must correct the
seepage problem or shutdown its plant. To correct
the problem, L pays an amount to add a concrete lin-
ing to the walls from the floor to a height of about four
feet and also to add concrete to the floor of the plant.
Under paragraphs (e)(2)(ii) and (j)(2)(ii) of this sec-
tion, an amount is paid to improve a building unit of
property if the amount is paid for a betterment to the
building structure or any building system. The walls
are part of the building structure as defined in para-
graph (e)(2)(ii)(A) of this section. The condition ne-
cessitating the expenditure was the seepage of the oil
into the plant. Prior to the seepage, the walls did not
leak and were functioning for their intended use. L is
not required to treat the amount paid as a betterment
under paragraphs (j)(1)(ii) and (j)(2)(iv) of this sec-
tion because it is not paid for a material addition to,
or a material increase in the capacity of, the building’s
structure as compared to the condition of the structure
prior to the seepage of oil. Moreover, the amount paid
is not reasonably expected to materially increase the
productivity, efficiency, strength, quality, or output of
the building structure under paragraphs (j)(1)(iii) and
(j)(2)(iv) as compared to the condition of the structure
prior to the seepage of the oil. Therefore, L is not re-
quired to treat the amount paid to correct the seepage
as a betterment to the building under paragraph (d)(1)
or (j) of this section. The federal inspectors’ require-
ment that L correct the seepage to continue operating
the plant is not relevant in determining whether the
amount paid improves the plant.
Example 13.Not a betterment; new roof mem-
brane
. M owns a building that it uses for its retail
business. Over time, the waterproof membrane (top
layer) on the roof of M’s building begins to wear,
and M began to experience water seepage and leaks
throughout its retail premises. To eliminate the prob-
lems, a contractor recommends that M put a new rub-
ber membrane on the worn membrane. Accordingly,
M pays the contractor to add the new membrane. The
new membrane is comparable to the worn membrane
when it was originally placed in service by the tax-
payer. Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a building
2013–43 I.R.B.381October 21, 2013

unit of property if the amount is paid for a betterment
to the building structure or any building system. The
roof is part of the building structure under paragraph
(e)(2)(ii)(A) of this section. The condition necessitat-
ing the expenditure was the normal wear of M’s roof.
Under paragraph (j)(2)(iv) of this section, to deter-
mine whether the amounts are for a betterment, the
condition of the building structure after the expendi-
ture must be compared to the condition of the struc-
ture when M placed the building into service because
M has not previously corrected the effects of normal
wear and tear. Under these facts, the amount paid to
add the new membrane to the roof is not for a ma-
terial addition or a material increase in the capacity
of the building structure under paragraph (j)(1)(ii) of
this section as compared to the condition of the struc-
ture when it was placed in service. Moreover, the new
membrane is not reasonably expected to materially
increase the productivity, efficiency, strength, quality,
or output of the building structure under paragraph
(j)(1)(iii) of this section as compared to the condition
of the building structure when it was placed in ser-
vice. Therefore, M is not required to treat the amount
paid to add the new membrane as a betterment to the
building under paragraph (d)(1) or (j) of this section.
Example 14.Material increase in capacity;
building
. N owns a factory building with a stor-
age area on the second floor. N pays an amount to
reinforce the columns and girders supporting the
second floor to permit storage of supplies with a
gross weight 50 percent greater than the previous
load-carrying capacity ofthe storage area. Under
paragraphs (e)(2)(ii) and (j)(2)(ii) of this section, an
amount is paid to improve a building unit of property
if the amount is paid for a betterment to the building
structure or any building system. The columns and
girders are part of the building structure defined
under paragraph (e)(2)(ii)(A) of this section. N must
treat the amount paid to reinforce the columns and
girders as a betterment under paragraphs (j)(1)(ii)
and (j)(1)(iii) of this section because it materially in-
creases the load-carrying capacity and the strength of
the building structure. Therefore, N must capitalize
this amount as an improvement to the building under
paragraphs (d)(1) and (j) of this section.
Example 15.Material increase in capacity; chan-
nel.
O owns harbor facilities consisting of a slip for
the loading and unloading of barges and a channel
leading from the slip to the river. At the time of
purchase, the channel was 150 feet wide, 1,000 feet
long, and 10 feet deep. Several years after purchasing
the harbor facilities, to allow for ingress and egress
and for the unloading of larger barges, O decides to
deepen the channel to a depth of 20 feet. O pays a
contractor to dredge the channel to 20 feet. Assume
the channel is the unit of property. O must capitalize
the amounts paid for the dredging as an improvement
to the channel because they are for a material increase
in the capacity of the unit of property under paragraph
(j)(1)(ii) of this section.
Example 16. Not a material increase in capac-
ity; channel
. Assume the same facts as inExample
15
, except that the channel was susceptible to silta-
tion and, after dredging to 20 feet, the channel depth
had been reduced to 18 feet. O pays a contractor to
redredge the channel to a depth of 20 feet. The expen-
diture was necessitated by the siltation of the channel.
Both prior to the siltation and after the redredging, the
depth of the channel was 20 feet. Applying the com-
parison rule under paragraph (j)(2)(iv) of this section,
the amounts paid by O to redredge the channel are not
for a betterment under paragraph (j)(1)(ii) of this sec-
tion because they are not for amaterial addition to, or
a material increase in the capacity of, the unit of prop-
erty as compared to the condition of the property prior
to the siltation. Similarly, these amounts are not for a
betterment under paragraph (j)(1)(iii) of this section
because the amounts are not reasonably expected to
increase the productivity, efficiency, strength, quality,
or output of the unit of property as compared to the
condition of the property before the siltation. There-
fore, O is not required to capitalize these amounts as
improvement under paragraphs (d)(1) and (j) of this
section.
Example 17.Material increase in capacity; chan-
nel
. Assume the same facts as inExample 16except
that after the redredging, there is more siltation, and
the channel depth is reduced back to 18 feet. In ad-
dition, to allow for additional ingress and egress and
for the unloading of even larger barges, O decides to
deepen the channel to a depth of 25 feet. O pays a
contractor to redredge the channel to 25 feet. O must
capitalize the amounts paid for the dredging as an im-
provement to the channel because the amounts are for
a material increase in the capacity of the unit of prop-
erty under paragraph (j)(1)(ii) of this section as com-
pared to condition of the unit of property before the
siltation. As part of this improvement, O is also re-
quired to capitalize the portion of the redredge costs
allocable to restoring the depth lost to the siltation be-
cause, under paragraph (g)(1)(i) of this section, these
amounts directly benefit and are incurred by reason
of the improvement to the unit of property.
Example 18.Not a material increase in capac-
ity; building
. P owns a building used in its trade or
business. The first floor has a drop-ceiling. To fully
expose windows on the first floor, P pays an amount
to remove the drop-ceiling and repaint the original
ceiling. Under paragraphs (e)(2)(ii) and (j)(2)(ii) of
this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a bet-
terment to the building structure or any building sys-
tem. The ceiling is part of the building structure as
defined under paragraph (e)(2)(ii)(A) of this section.
P is not required to treat the amount paid to remove
the drop-ceiling as a betterment to the building be-
cause it was not for a material addition or material
increase in the capacity of the building structure un-
der paragraph (j)(1)(ii) of this section and it was not
reasonably expected to materially increase to the ef-
ficiency, strength, or quality of the building structure
under paragraph (j)(1)(iii) of this section. In addi-
tion, under paragraph (j)(2)(i) of this section, because
the effect on productivity and output of the building
structure cannot be measured in this context, these
factors are not relevant in determining whether there
is a betterment to the building structure.
Example 19. Material increase in capacity;
building
. Q owns a building that it uses in its retail
business. The building contains one floor of retail
space with very high ceilings. Q pays an amount to
add a stairway and a mezzanine for the purposes of
adding additional selling space within its building.
Under paragraphs (e)(2)(ii) and (j)(2)(ii) of this sec-
tion, an amount is paid to improve a building unit
of property if the amount is paid for a betterment to
the building structure or any building system. The
stairway and the mezzanine are part of the building
structure as defined under paragraph (e)(2)(ii)(A)
of this section. Q is required to treat the amount
paid to add the stairway and mezzanine as a bet-
terment because it is for a material addition to, and
an increase in the capacity of, the building structure
under paragraph (j)(1)(ii) of this section. Therefore,
Q must capitalize this amount as an improvement to
the building unit of property under paragraphs (d)(1)
and (j) of this section.
Example 20.Not material increase in efficiency;
HVAC system
. R owns an office building that it
uses to provide services to customers. The build-
ing contains an HVAC system that incorporates
10 roof-mounted units that provide heating and air
conditioning for different parts of the building. The
HVAC system also consists of controls for the entire
system and duct work that distributes the heated or
cooled air to the various spaces in the building’s in-
terior. After many years of use of the HVAC system,
R begins to experience climate control problems in
various offices throughout the office building and
consults with a contractor to determine the cause.
The contractor recommends that R replace two of
the roof-mounted units. R pays an amount to re-
place the two specified units. The two new units are
expected to eliminate the climate control problems
and to be 10 percent more energy efficient than the
replaced units in their original condition. No work is
performed on the other roof-mounted heating/cool-
ing units, the duct work, or the controls. Under
paragraphs (e)(2)(ii) and (j)(2)(ii) of this section, an
amount is paid to improve a building unit of property
if the amount is paid for a betterment to the building
structure or any building system. The HVAC system,
including the two-roof mounted units, is a building
system under paragraph (e)(2)(ii)(B)(
1)ofthissec-
tion. The replacement of the two roof-mounted units
is not a material addition to or a material increase in
the capacity of the HVAC system under paragraphs
(j)(1)(ii) and (j)(3)(ii) of this section as compared
to the condition of the system prior to the climate
control problems. In addition, given the 10 percent
efficiency increase in two units of the entire HVAC
system, the replacement is not expected to materially
increase the productivity, efficiency, strength, qual-
ity, or output of the HVAC system under paragraphs
(j)(1)(iii) and (j)(2)(iv) of this section as compared
to the condition of the system prior to the climate
control problems. Therefore, R is not required to
capitalize the amounts paid for these replacements
as betterments to the building unit of property under
paragraphs (d)(1) and (j) of this section.
Example 21.Material increase in efficiency;
building
. S owns a building that it uses in its ser-
vice business. S conducts an energy assessment
and determines that it could significantly reduce its
energy costs by adding insulation to its building. S
pays an insulation contractor to apply a combination
of loose-fill, spray foam, and blanket insulation
throughout S’s building structure, including within
the attic, walls, and crawl spaces. S reasonably ex-
pects the new insulation to make the building more
energy efficient because the contractor indicated that
the new insulation would reduce its annual energy
and power costs by approximately 50 percent of
its annual costs during the last five years. Under
paragraphs (e)(2)(ii) and (j)(2)(ii) of this section, an
amount is paid to improve a building if the amount is
paid for a betterment to the building structure or any
October 21, 20133822013–43 I.R.B.

building system. Therefore, under paragraphs (d)(1)
and (j) of this section, S must capitalize as a better-
ment the amount paid to add the insulation because
the insulation is reasonably expected to materially
increase the efficiency of the building structure under
paragraph (j)(1)(iii) of this section.
Example 22.Material addition; building.Towns
and operates a restaurant, which provides a variety
of prepared foods to its customers. To better accom-
modate its customers and increase customer traffic,
T decides to add a drive-through service area. As
a result, T pays amounts to partition an area within
its restaurant for a drive-through service counter, to
construct a service window with necessary security
features, to build an overhang for vehicles, and to
construct a drive-up menu board. Assume that the
drive-up menu board is section 1245 property that is
a separate unit of property under paragraph (e)(3) of
this section. Under paragraphs (e)(2)(ii) and (j)(2)(ii)
of this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a better-
ment to the building structure or any building system.
The amounts paid for the partition, service window
and overhang are betterments to the building struc-
ture because they comprise a material addition (that
is, a physical expansion, extension, and addition of
a major component) to the building structure under
paragraph (j)(1)(ii) of this section. Accordingly, T
must capitalize as an improvement the amounts paid
to add the partition, drive-through window, and over-
hang under paragraphs (d)(1) and (j) of this section.
T is also required to capitalize the amounts paid to
acquire and install each section 1245 property in ac-
cordance with §1.263(a)–2(d)(1).
Example 23.Costs incurred during betterment.U
owns a building that it uses in its service business. To
accommodate new employees and equipment, U pays
amounts to increase the load capacity of its electrical
system by adding a second electrical panel with addi-
tional circuits and adding wiring and outlets through-
out the electrical system of its building. To com-
plete the upgrades to the electrical system, the con-
tractor makes several holes in walls. As a result, U
also incurs costs to patch the holes and repaint sev-
eral walls. Under paragraphs (e)(2)(ii) and (j)(2)(ii)
of this section, an amount is paid to improve a build-
ing unit of property if the amount is paid for a better-
ment to the building structure or any building system.
The amounts paid to upgrade the panel and wiring
are for betterments to U’s electrical system because
they increase the capacity of the electrical system un-
der paragraph (j)(1)(ii) of this section and increase
the strength and output ofthe electrical system un-
der paragraph (j)(1)(iii) of this section. Accordingly,
U is required to capitalize the costs of the upgrade to
the electrical system as an improvement to the build-
ing unit of property under paragraphs (d)(1) and (j) of
this section. Moreover, under paragraph (g)(1) of this
section, U is required to capitalize the amounts paid
to patch holes and repaint several walls in its building
because these costs directly benefit and are incurred
by reason of the improvement to U’s building unit of
property.
(k)Capitalization of restorations—(1)
In general. A taxpayer must capitalize as
an improvement an amount paid to restore
a unit of property, including an amount
paid to make good the exhaustion for
which an allowance is or has been made.
An amount restores a unit of property only
if it—
(i) Is for the replacement of a compo-
nent of a unit of property for which the tax-
payer has properly deducted a loss for that
component, other thana casualty loss un-
der §1.165–7;
(ii) Is for the replacement of a compo-
nent of a unit of property for which the tax-
payer has properly taken into account the
adjusted basis of the component in realiz-
ing gain or loss resulting from the sale or
exchange of the component;
(iii) Is for the restoration of damage to
a unit of property for which the taxpayer
is required to take a basis adjustment as a
result of a casualty loss under section 165,
or relating to a casualty event described
in section 165, subject to the limitation in
paragraph (k)(4) of this section;
(iv) Returns the unit of property to its
ordinarily efficient operating condition if
the property has deteriorated to a state of
disrepair and is no longer functional for its
intended use;
(v) Results in the rebuilding of the unit
of property to a like-new condition after
the end of its class life as defined in para-
graph (i)(4) of this section (see paragraph
(k)(5) of this section); or
(vi) Is for the replacement of a part or a
combination of parts that comprise a major
component or a substantial structural part
of a unit of property (see paragraph (k)(6)
of this section).
(2)Application of restorations to
buildings. An amount is paid to im-
proveabuildingifitispaidtorestore
(as defined under paragraph (k)(1) of
this section) a property specified under
paragraph (e)(2)(ii) (building), paragraph
(e)(2)(iii)(B) (condominium), paragraph
(e)(2)(iv)(B) (cooperative), or paragraph
(e)(2)(v)(B) (leased building or portion
of building) of this section. For example,
an amount is paid to improve a building
if it is paid for the replacement of a part
or combination of parts that comprise a
major component or substantial structural
part of the building structure or any one
of its building systems (for example, the
HVAC system). See paragraph (k)(6) of
this section.
(3)Exception for losses based on sal-
vage value. A taxpayer is not required to
treat as a restoration amounts paid under
paragraph (k)(1)(i) or paragraph (k)(1)(ii)
of this section if the unit of property has
been fully depreciated and the loss is at-
tributable only to remaining salvage value
as computed for federal income tax pur-
poses.
(4)Restoration of damage from casu-
alty—(i)Limitation. For purposes of para-
graph (k)(1)(iii) of this section, the amount
paid for restoration of damage to the unit
of property that mustbe capitalized under
this paragraph (k) is limited to the excess
(ifany)of—
(A) The amount prescribed by
§1.1011–1 as the adjusted basis of
the single, identifiable property (under
§1.167–7(b)(2)(i)) for determining the loss
allowable on account of the casualty, over
(B) The amount paid for restoration
of damage to the unit of property under
paragraph (k)(1)(iii) of this section that
also constitutes an improvement under any
other provision of paragraph (k)(1) of this
section.
(ii)Amounts in excess of limitation.The
amounts paid for restoration of damage to
a unit of property as described in para-
graph (k)(1)(iii) of this section, but that ex-
ceed the limitation provided in paragraph
(k)(4)(i) of this section, must be treated in
accordance with the provisions of the In-
ternal Revenue Code and regulations that
are otherwise applicable. See, for exam-
ple, §1.162–4 (repairs and maintenance);
§1.263(a)–2 (costs to acquire and produce
units of property); and §1.263(a)–3 (costs
to improve units of property).
(5)Rebuild to like-new condition.For
purposes of paragraph (k)(1)(v) of this
section, a unit of property is rebuilt to a
like-new condition if it is brought to the
status of new, rebuilt, remanufactured, or
a similar status under the terms of any fed-
eral regulatory guideline or the manufac-
turer’s original specifications. Generally,
a comprehensive maintenance program,
even though substantial, does not return a
unit of property to a like-new condition.
(6)Replacement of a major component
or a substantial structural part—(i)In
general. To determine whether an amount
is for the replacement of a part or a com-
bination of parts that comprise a major
component or a substantial structural part
of the unit of property under paragraph
(k)(1)(vi) of this section, it is appropriate
to consider all the facts and circumstances.
These facts and circumstances include the
quantitative and qualitative significance of
2013–43 I.R.B.383October 21, 2013

the part or combination of parts in relation
to the unit of property.
(A)Major component.Amajorcom-
ponent is a part or combination of parts
that performs a discrete and critical func-
tion in the operation of the unit of prop-
erty. An incidental component of the unit
of property, even though such component
performs a discrete and critical function in
the operation of the unit of property, gen-
erally will not, by itself, constitute a major
component.
(B)Substantial structural part.Asub-
stantial structural part is a part or combina-
tion of parts that comprises a large portion
of the physical structure of the unit of prop-
erty.
(ii)Major components and substantial
structural parts of buildings. In the case
of a building, an amount is for the replace-
ment of a major component or a substantial
structural part of the building unit of prop-
erty if—
(A) The replacement includes a part
or combination of parts that comprise a
major component (as defined in para-
graph(k)(6)(i)(A)ofthissection),ora
significant portion of a major component,
of any of the properties designated in
paragraph (e)(2)(ii) (building), paragraph
(e)(2)(iii)(B) (condominium), paragraph
(e)(2)(iv)(B) (cooperative), or paragraph
(e)(2)(v)(B) (leased building or leased
portion of a building) of this section; or
(B) The replacement includes a part
or combination of parts that comprises
a large portion of the physical structure
of any of the properties designated in
paragraph (e)(2)(ii) (building), paragraph
(e)(2)(iii)(B) (condominium), paragraph
(e)(2)(iv)(B) (cooperative), or paragraph
(e)(2)(v)(B) (leased building or portion of
building) of this section.
(7)Examples. The following examples
illustrate the application of this paragraph
(k) only and do not address whether capi-
talization is required under another provi-
sion of this section or another provision of
the Code (for example, section 263A). Un-
less otherwise stated, assume that the tax-
payer has not properly deducted a loss for,
nor taken into account the adjusted basis
on a sale or exchange of, any unit of prop-
erty, asset, or component of a unit of prop-
erty that is replaced.
Example 1.Replacement of loss component.A
owns a manufacturing building containing various
types of manufacturing equipment. A does a cost
segregation study of the manufacturing building and
properly determines that a walk-in freezer in the man-
ufacturing building is section 1245 property as de-
fined in section 1245(a)(3). The freezer is not part
of the building structure or the HVAC system under
paragraph (e)(2)(i) or (e)(2)(ii)(B)(
1) of this section.
Several components of the walk-in freezer cease to
function, and A decides to replace them. A abandons
the old freezer components and properly recognizes
a loss from the abandonment of the components. A
replaces the abandoned freezer components with new
components and incurs costs to acquire and install the
new components. Under paragraph (k)(1)(i) of this
section, A must capitalize the amounts paid to ac-
quire and install the new freezer components because
A replaced components for which it had properly de-
ducted a loss.
Example 2.Replacement of sold component.As-
sume the same facts as in
Example 1, except that
A did not abandon the components but instead sold
them to another party and properly recognized a loss
on the sale. Under paragraph (k)(1)(ii) of this sec-
tion, A must capitalize the amounts paid to acquire
and install the new freezer components because A re-
placed components for which it had properly taken
into account the adjusted basis of the components in
realizing a loss from the sale of the components.
Example 3.Restoration after casualty loss.B
owns an office building that it uses in its trade or busi-
ness. A storm damages the office building at a time
when the building has an adjusted basis of $500,000.
B deducts under section 165 a casualty loss in the
amount of $50,000, and properly reduces its basis in
the office building to $450,000. B hires a contractor
to repair the damage to the building, including the re-
pair of the building roof and the removal of debris
from the building premises. B pays the contractor
$50,000 for the work. Under paragraph (k)(1)(iii) of
this section, B must treat the $50,000 amount paid to
the contractor as a restoration of the building structure
because B properly adjusted its basis in that amount
as a result of a casualty loss under section 165, and the
amount does not exceed the limit in paragraph (k)(4)
of this section. Therefore, B must treat the amount
paid as an improvement to the building unit of prop-
erty and, under paragraph (d)(2) of this section, must
capitalize the amount paid.
Example 4.Restoration after casualty event.As-
sume the same facts as in
Example 3,exceptthatB
receives insurance proceeds of $50,000 after the ca-
sualty to compensate for its loss. B cannot deduct a
casualty loss under section 165 because its loss was
compensated by insurance. However, B properly re-
duces its basis in the property by the amount of the in-
surance proceeds. Under paragraph (k)(1)(iii) of this
section, B must treat the $50,000 amount paid to the
contractor as a restoration of the building structure
because B has properly taken a basis adjustment re-
lating to a casualty event described in section 165,
and the amount does not exceed the limit in para-
graph (k)(4) of this section. Therefore, B must treat
the amount paid as an improvement to the building
unit of property and, under paragraph (d)(2) of this
section, must capitalize the amount paid.
Example 5.Restoration after casualty loss; lim-
itation
. (i) C owns a building that it uses in its trade
or business. A storm damages the building at a time
when the building has an adjusted basis of $500,000.
C determines that the cost of restoring its property is
$750,000, deducts a casualty loss under section 165
in the amount of $500,000, and properly reduces its
basis in the building to $0. C hires a contractor to
repair the damage to the building and pays the con-
tractor $750,000 for the work. The work involves re-
placing the entire roof structure of the building at a
cost of $350,000 and pumping water from the build-
ing, cleaning debris from the interior and exterior, and
replacing areas of damaged dry wall and flooring at a
cost of $400,000. Although resulting from the casu-
alty event, the pumping, cleaning, and replacing dam-
aged drywall and flooring, does not directly benefit
and is not incurred by reason of the roof replacement.
(ii) Under paragraph (k)(1)(vi) of this section,
C must capitalize as an improvement the $350,000
amount paid to the contractor to replace the roof
structure because the roof structure constitutes a
major component and a substantial structural part
of the building unit of property. In addition, under
paragraphs (k)(1)(iii) and (k)(4)(i), C must treat as a
restoration the remaining costs, limited to the excess
of the adjusted basis of the building over the amounts
paid for the improvement under paragraph (k)(1)(vi).
Accordingly, C must treat as a restoration $150,000
($500,000 - $350,000) of the $400,000 paid for the
portion of the costs related to repairing and cleaning
the building structure under paragraph (k)(1)(iii) of
this section. Thus, in addition to the $350,000 to
replace the roof structure, C must also capitalize the
$150,000 as an improvement to the building unit of
property under paragraph (d)(2) of this section. C
is not required to capitalize the remaining $250,000
repair and cleaning costs under paragraph (k)(1)(iii)
of this section.
Example 6.Restoration of property in a state of
disrepair
. D owns and operates a farm with several
barns and outbuildings. D did not use or maintain one
of the outbuildings on a regular basis, and the out-
building fell into a state of disrepair. The outbuild-
ing previously was used for storage but can no longer
be used for that purpose because the building is not
structurally sound. D decides to restore the outbuild-
ing and pays an amount to shore up the walls and
replace the siding. Under paragraphs (e)(2)(ii) and
(k)(2) of this section, an amount is paid to improve
a building if the amount is paid to restore the build-
ing structure or any building system. The walls and
siding are part of the building structure under para-
graph (e)(2)(ii)(A) of this section. Under paragraph
(k)(1)(iv) of this section, D must treat the amount
paid to shore up the walls and replace the siding as
a restoration of the building structure because the
amounts return the building structure to its ordinarily
efficient operating condition after it had deteriorated
to a state of disrepair and was no longer functional for
its intended use. Therefore, D must treat the amount
paid to shore up the walls and replace the siding as
an improvement to the building unit of property and,
under paragraph (d)(2) of this section, must capitalize
the amount paid.
Example 7.Rebuild of property to like-new con-
dition before end of class life
. E is a Class I rail-
road that owns a fleet of freight cars. Assume the
freight cars have a recovery period of 7 years un-
dersection168(c)andaclasslifeof14years. Ev-
ery 8 to 10 years, E rebuilds its freight cars. Ten
years after E places the freight car in service, E per-
forms a rebuild to the manufacturer’s original speci-
fication, which includes a complete disassembly, in-
October 21, 20133842013–43 I.R.B.

spection, and reconditioning or replacement of com-
ponents of the suspension and draft systems, trailer
hitches, and other specialequipment. E also modi-
fies the car to upgrade various components to the lat-
est engineering standards. The freight car is stripped
to the frame, with all of its substantial components
either reconditioned or replaced. The frame itself
is the longest-lasting part of the car and is recondi-
tioned. The walls of the freight car are replaced or
are sandblasted and repainted. New wheels are in-
stalled on the car. All the remaining components of
the car are restored before they are reassembled. At
the end of the rebuild, the freight car has been restored
to like-new condition under the manufacturer’s spec-
ifications. Assume the freight car is the unit of prop-
erty. E is not required to treat as an improvement
and capitalize the amounts paid to rebuild the freight
car under paragraph (k)(1)(v) of this section because,
although the amounts paid restore the freight car to
like-new condition, the amounts were not paid after
the end of the class life of the freight car. However,
see paragraphs (k)(1)(vi) and (k)(6) of this section to
determine whether any amounts must be capitalized
because they are paid for the replacement of a major
component or a substantial structural part of the unit
of property.
Example 8.Rebuild of property to like-new con-
dition after end of class life
. Assume the same facts
as in
Example 7, except that E rebuilds the freight
car 15 years after E places it in service. Under para-
graph (k)(1)(v) of this section, E must treat as an im-
provement and capitalize the amounts paid to rebuild
the freight car because the amounts paid restore the
freight car to like-new condition after the end of the
class life of the freight car.
Example 9.Not a rebuild to a like-new condi-
tion
. F is a commercial airline engaged in the busi-
ness of transporting freight and passengers. To con-
duct its business, F owns several aircraft. As a con-
dition of maintaining its airworthiness certificates, F
is required by the FAA to establish and adhere to a
continuous maintenance program for each aircraft in
its fleet. F performs heavy maintenance on its air-
frames every 8 to 10 years. In Year 1, F purchased
an aircraft for $15 million. In Year 16, F paid $2 mil-
lion for the labor and materials necessary to perform
the second heavy maintenance visit on the airframe
of an aircraft. To perform the heavy maintenance
visit, F extensively disassembles the airframe, remov-
ing items such as engines, landing gear, cabin and
passenger compartment seats, side and ceiling pan-
els, baggage stowage bins, galleys, lavatories, floor
boards, cargo loading systems, and flight control sur-
faces. As specified by F’s maintenance manual for
the aircraft, F then performs certain tasks on the dis-
assembled airframe for the purpose of preventing de-
terioration of the inherent safety and reliability lev-
els of the airframe. These tasks include lubrication
and service, operational and visual checks, inspection
and functional checks, reconditioning of minor parts
and components, and removal, discard, and replace-
ment of certain life-limited single cell parts, such as
cartridges, canisters, cylinders, and disks. Recondi-
tioning of parts includes burnishing corrosion, repair-
ing cracks, dents, gouges, punctures, tightening or
replacing loose or missing fasteners, replacing dam-
aged seals, gaskets, or valves, and similar activities.
In addition to the tasks described above, to comply
with certain FAA airworthiness directives, F inspects
specific skin locations, applies doublers over small
areas where cracks were found, adds structural rein-
forcements, and replaces skin panels on a small sec-
tion of the fuselage. However, the heavy maintenance
does not include the replacement of any major com-
ponents or substantial structural parts of the aircraft
with new components. In addition, the heavy main-
tenance visit does not bring the aircraft to the status of
new, rebuilt, remanufactured, or a similar status under
FAA guidelines or the manufacturer’s original spec-
ifications. After the heavy maintenance, the aircraft
was reassembled. Assume the aircraft, including the
engines, is a unit of property and has a class life of
12 years under section 168(c). Although the heavy
maintenance is performed after the end of the class
life of the aircraft, F is not required to treat the heavy
maintenance as a restoration and improvement of the
unit of property under paragraph (k)(1)(v) of this sec-
tion because, although extensive, the amounts paid do
not restore the aircraft to like-new condition. See also
paragraph (i)(1)(iii) of this section for the application
of the safe harbor for routine maintenance.
Example 10.Replacement of major component or
substantial structural part; personal property
.Gisa
common carrier that owns a fleet of petroleum haul-
ing trucks. G pays amounts to replace the existing
engine, cab, and petroleum tank with a new engine,
cab, and tank. Assume the tractor of the truck (which
includes the cab and the engine) is a single unit of
property and that the trailer (which contains the pe-
troleum tank) is a separate unit of property. The new
engine and the cab each constitute a part or combi-
nation of parts that comprise a major component of
G’s tractor, because they perform a discrete and crit-
ical function in the operation of the tractor. In ad-
dition, the cab constitutes a part or combination of
parts that comprise a substantial structural part of G’s
tractor. Therefore, the amounts paid for the replace-
ment of the engine and the cab must be capitalized
under paragraph (k)(1)(vi) of this section. Moreover,
the new petroleum tank constitutes a part or combina-
tion of parts that comprise a major component and a
substantial structural part of the trailer. Accordingly,
the amounts paid for the replacement of the tank also
must be capitalized under paragraph (k)(1)(vi) of this
section.
Example 11.Repair performed during restora-
tion
. Assume the same facts as inExample 10, except
that, at the same time the engine and cab of the tractor
are replaced, G pays amounts to paint the cab of the
tractor with its company logo and to fix a broken tail-
light on the tractor. The repair of the broken taillight
and the painting of the cab generally are deductible
expenses under §1.162–4. However, under paragraph
(g)(1)(i) of this section, a taxpayer must capitalize all
the direct costs of an improvement and all the indirect
costs that directly benefit or are incurred by reason
of an improvement. Repairs and maintenance that do
not directly benefit or are not incurred by reason of an
improvement are not required to be capitalized under
section 263(a), regardless of whether they are made
at the same time as an improvement. For the amounts
paid to paint the logo on the cab, G’s need to paint the
logo arose from the replacement of the cab with a new
cab. Therefore, under paragraph (g)(1)(i) of this sec-
tion, G must capitalize the amounts paid to paint the
cab as part of the improvement to the tractor because
these amounts directly benefit and are incurred by
reason of the restoration of the tractor. The amounts
paid to repair the broken taillight are not for the re-
placement of a major component, do not directly ben-
efit, and are not incurred by reason of the replacement
of the cab or the engine under paragraph (g)(1)(i) of
this section, even thoughthe repair was performed at
the same time as these replacements. Thus, G is not
required to capitalize the amounts paid to repair the
broken taillight.
Example 12.Related amounts to replace major
component or substantial structural part; personal
property
. (i) H owns a retail gasoline station, consist-
ing of a paved area used for automobile access to the
pumps and parking areas, a building used to market
gasoline, and a canopy covering the gasoline pumps.
The premises also consist of underground storage
tanks (USTs) that are connected by piping to the
pumps and are part of the gasoline pumping system
used in the immediate retail sale of gas. The USTs
are components of the gasoline pumping system. To
comply with regulations issued by the Environmen-
tal Protection Agency, H is required to remove and
replace leaking USTs. In Year 1, H hires a contrac-
tor to perform the removal and replacement, which
consists of removing the old tanks and installing new
tanks with leak detection systems. The removal of
the old tanks includes removing the paving material
covering the tanks, excavating a hole large enough
to gain access to the old tanks, disconnecting any
strapping and pipe connections to the old tanks, and
lifting the old tanks out of the hole. Installation of
the new tanks includes placement of a liner in the
excavated hole, placement of the new tanks, instal-
lation of a leak detection system, installation of an
overfill system, connection of the tanks to the pipes
leading to the pumps, backfilling of the hole, and
replacement of the paving. H also is required to pay a
permit fee to the county to undertake the installation
of the new tanks.
(ii) H pays the permit fee to the county on October
15, Year 1. On December 15, Year 1, the contractor
completes the removal of the old USTs and bills H
for the costs of removal. On January 15, Year 2, the
contractor completes the installation of the new USTs
and bills H for the remainder of the work. Assume
that H computes its taxes on a calendar year basis
and H’s gasoline pumping system is the unit of prop-
erty. Under paragraph (k)(1)(vi) of this section, H
must capitalize the amounts paid to replace the USTs
as a restoration to the gasoline pumping system be-
cause the USTs are parts or combinations of parts that
comprise a major component and substantial struc-
tural part of the gasoline pumping system. Moreover,
under paragraph (g)(2) of this section, H must capi-
talize the costs of removing the old USTs because H
has not taken a loss on the disposition of the USTs,
and the amounts to remove the USTs directly benefit
and are incurred by reasonof the restoration of, and
improvement to, the gasoline pumping system. In ad-
dition, under paragraph (g)(1) of this section, H must
capitalize the permit fees because they directly ben-
efit and are incurred by reason of the improvement
to the gasoline pumping system. Finally, under para-
graph (g)(3) of this section, H must capitalize the re-
lated amounts paid to improve the gasoline pumping
system, including the permit fees, the amount paid to
remove the old USTs, and the amount paid to install
the new USTs, even though the amounts were sepa-
rately invoiced, paid to different parties, and incurred
in different tax years.

Example 13.Not replacement of major compo-
nent; incidental
. J owns a machine shop in which it
makes dies used by manufacturers. In Year 1, J pur-
chased a drill press for use in its production process.
In Year 3, J discovers that the power switch assem-
bly, which controls the supply of electric power to
the drill press, has become damaged and cannot op-
erate. To correct this problem, J pays amounts to
replace the power switch assembly with comparable
and commercially available replacement parts. As-
sume that the drill press is a unit of property under
paragraph (e) of this section and the power switch as-
sembly is a small component of the drill press that
may be removed and installed with relative ease. The
power switch assembly is not a major component of
the unit of property under paragraph (k)(6)(i)(A) of
this section because, although the power assembly
may affect the function of J’s drill press by control-
ling the supply of electric power, the power assembly
is an incidental component of the drill press. In addi-
tion, the power assembly is not a substantial structural
part of J’s drill press under paragraph (k)(6)(i)(B) of
this section. Therefore, J is not required to capitalize
the costs to replace the power switch assembly under
paragraph (k)(1)(vi) of this section.
Example 14.Replacement of major component
or substantial structural part; roof
. K owns a man-
ufacturing building. K discovers several leaks in the
roof of the building and hires a contractor to inspect
and fix the roof. The contractor discovers that a ma-
jorportionofthedeckinghasrottedandrecommends
the replacement of the entire roof. K pays the con-
tractor to replace the entire roof, including the deck-
ing, insulation, asphalt, and various coatings. Un-
der paragraphs (e)(2)(ii) and (k)(2) of this section, an
amount is paid to improve a building if the amount is
paid to restore the building structure or any building
system. The roof is part of the building structure as
defined under paragraph (e)(2)(ii)(A) of this section.
Because the entire roof performs a discrete and criti-
cal function in the building structure, the roof com-
prises a major component of the building structure
under paragraph (k)(6)(ii)(A) of this section. In addi-
tion, because the roof comprises a large portion of the
physical structure of the building structure, the roof
comprises a substantial structural part of the build-
ing structure under paragraph (k)(6)(ii)(B) of this sec-
tion. Therefore, under either analysis, K must treat
the amount paid to replace the roof as a restoration of
thebuildingunderparagraphs(k)(1)(vi)and(k)(2)of
this section and must capitalize the amount paid as an
improvement under paragraph (d)(2) of this section.
Example 15.Not replacement of major compo-
nent or substantial structural part; roof membrane
.
L owns a building in which it conducts its retail busi-
ness. The roof decking over L’s building is covered
with a waterproof rubber membrane. Over time, the
rubber membrane begins to wear, and L begins to ex-
perience leaks into its retail premises. However, the
building is still functioning in L’s business. To elim-
inate the problems, a contractor recommends that L
replace the membrane on the roof with a new rub-
ber membrane. Accordingly, L pays the contractor to
strip the original membrane and replace it with a new
rubber membrane. The new membrane is compara-
ble to the original membrane but corrects the leakage
problems. Under paragraphs (e)(2)(ii) and (k)(2) of
this section, an amount is paid to improve a build-
ing if the amount is paid to restore the building struc-
ture or any building system. The roof, including the
membrane, is part of the building structure as defined
under paragraph (e)(2)(ii)(A) of this section. Be-
cause the entire roof performs a discrete and critical
function in the building structure, the roof comprises
a major component of the building structure under
paragraph (k)(6)(ii)(A) of this section. Although the
replacement membrane may aid in the function of the
building structure, it does not, by itself, comprise a
significant portion of the roof major component un-
der paragraph (k)(6)(ii)(A) of this section. In addi-
tion, the replacement membrane does not comprise a
substantial structural part of L’s building structure un-
der paragraph (k)(6)(ii)(B) of this section. Therefore,
L is not required to capitalize the amount paid to re-
place the membrane as a restoration of the building
under paragraph (k)(1)(vi) of this section.
Example 16. Not a replacement of major com-
ponent or substantial structural part
;HVAC system.
M owns a building in which it operates an office
that provides medical services. The building con-
tains one HVAC system, which is comprised of three
furnaces, three air conditioning units, and duct work
that runs throughout the building to distribute the hot
or cold air throughout the building. One furnace in
M’s building breaks down, and M pays an amount
to replace it with a new furnace. Under paragraphs
(e)(2)(ii) and (k)(2) of this section, an amount is paid
to improve a building if the amount is paid to restore
the building structure or any building system. The
HVAC system, including the furnaces, is a building
system under paragraph (e)(2)(ii)(B)(
1)ofthissec-
tion. As the parts that provide the heating function
in the system, the three furnaces, together, perform a
discrete and critical function in the operation of the
HVAC system and are therefore a major component
of the HVAC system under paragraph (k)(6)(i)(A) of
this section. However, the single furnace is not a sig-
nificant portion of this major component of the HVAC
system under paragraph (k)(6)(ii)(A) of this section,
or a substantial structural part of the HVAC system
under paragraph (k)(6)(ii)(B) of this section. There-
fore, M is not required to treat the amount paid to re-
place the furnace as a restoration of the building under
paragraph (k)(1)(vi) of this section.
Example 17.Replacement of major component or
substantial structural part; HVAC system
. N owns a
large office building in which it provides consulting
services. The building contains one HVAC system,
which is comprised of one chiller unit, one boiler,
pumps, duct work, diffusers, air handlers, outside air
intake, and a cooling tower. The chiller unit includes
the compressor, evaporator, condenser, and expan-
sion valve, and it functions to cool the water used to
generate air conditioning throughout the building. N
pays an amount to replace the chiller with a compa-
rable unit. Under paragraphs (e)(2)(ii) and (k)(2) of
this section, an amount is paid to improve a building
if the amount is paid to restore the building structure
or any building system. The HVAC system, includ-
ing the chiller unit, is a building system under para-
graph (e)(2)(ii)(B)(
1) of this section. The chiller unit
performs a discrete and critical function in the opera-
tion of the HVAC system because it provides the cool-
ing mechanism for the entire system. Therefore, the
chiller unit is a major component of the HVAC sys-
tem under paragraph (k)(6)(ii)(A) of this section. Be-
cause the chiller unit comprises a major component
of a building system, N must treat the amount paid to
replace the chiller unit as a restoration to the building
under paragraphs (k)(1)(vi) and (k)(2) of this section
and must capitalize the amount paid as an improve-
ment to the building under paragraph (d)(2) of this
section.
Example 18.Not replacement of major compo-
nent or substantial structural part; HVAC system
.O
owns an office building that it uses to provide ser-
vices to customers. The building contains a HVAC
system that incorporates ten roof-mounted units that
provide heating and air conditioning for the building.
The HVAC system also consists of controls for the en-
tire system and duct work that distributes the heated
or cooled air to the various spaces in the building’s
interior. O begins to experience climate control prob-
lems in various offices throughout the office building
and consults with a contractor to determine the cause.
The contractor recommends that O replace three of
the roof-mounted heating and cooling units. O pays
an amount to replace the three specified units. No
work is performed on the other roof-mounted heating
and cooling units, the duct work, or the controls. Un-
der paragraphs (e)(2)(ii) and (k)(2) of this section, an
amount is paid to improve a building if the amount re-
stores the building structure or any building system.
The HVAC system, including the 10 roof-mounted
heating and cooling units, is a building system un-
der paragraph (e)(2)(ii)(B)(
1) of this section. As the
components that generate the heat and the air con-
ditioning in the HVAC system, the 10 roof-mounted
units, together, perform a discrete and critical func-
tionintheoperationoftheHVACsystemand,there-
fore, are a major component of the HVAC system un-
der paragraph (k)(6)(ii)(A) of this section. The three
roof-mounted heating and cooling units are not a sig-
nificant portion of a major component of the HVAC
system under (k)(6)(ii)(A) of this section, or a sub-
stantial structural part of the HVAC system, under
paragraph (k)(6)(ii)(B) of this section. Accordingly,
O is not required to treat the amount paid to replace
the three roof-mounted heating and cooling units as a
restoration of the building under paragraph (k)(1)(iv)
of this section.
Example 19.Replacement of major component or
substantial structural part; fire protection system
.P
owns a building that it uses to operate its business. P
pays an amount to replace the sprinkler system in the
building with a new sprinkler system. Under para-
graphs (e)(2)(ii) and (k)(2) of this section, an amount
is paid to improve a building if the amount restores
the building structure or any building system. The
fire protection and alarm system, including the sprin-
kler system, is a building system under paragraph
(e)(2)(ii)(B)(
6) of this section. As the component that
provides the fire suppression mechanism in the sys-
tem, the sprinkler system performs a discrete and crit-
ical function in the operation of the fire protection
and alarm system and is therefore a major compo-
nent of the system under paragraph (k)(6)(ii)(A) of
this section. Because the sprinkler system comprises
a major component of a building system, P must treat
the amount paid to replace the sprinkler system as
restoration to the building unit of property under para-
graphs (k)(1)(vi) and (k)(2) of this section and must
capitalize the amount paid as an improvement to the
building under paragraph (d)(2) of this section.
Example 20.Replacement of major component
or substantial structural part
;electrical system.Q
owns a building that it uses to operate its business. Q
October 21, 20133862013–43 I.R.B.

pays an amount to replace the wiring throughout the
building with new wiring that meets building code re-
quirements. Under paragraphs (e)(2)(ii) and (k)(2) of
this section, an amount is paid to improve a build-
ing if the amount restores the building structure or
any building system. The electrical system, includ-
ing the wiring, is a building system under paragraph
(e)(2)(ii)(B)(
3) of this section. As the component
that distributes the electricity throughout the system,
the wiring performs a discrete and critical function
in the operation of the electrical system under para-
graph (k)(6)(ii)(A) of this section. The wiring also
comprises a large portion of the physical structure of
the electrical system under paragraph (k)(6)(ii)(B) of
this section. Because the wiring comprises a major
component and a substantial structural part of a build-
ing system, Q must treat the amount paid to replace
the wiring as a restoration to the building under para-
graphs (k)(1)(vi) and (k)(2) of this section and must
capitalize the amount paid as an improvement to the
building under paragraph (d)(2) of this section.
Example 21.Not a replacement of major com-
ponent or substantial structural part; electrical sys-
tem
. R owns a building that it uses to operate its
business. R pays an amount to replace 30 percent of
the wiring throughout the building with new wiring
that meets building code requirements. Under para-
graphs (e)(2)(ii) and (k)(2) of this section, an amount
is paid to improve a building if the amount restores
the building structure or any building system. The
electrical system, including the wiring, is a building
system under paragraph (e)(2)(ii)(B)(
3)ofthissec-
tion. All the wiring in the building comprises a major
component because it performs a discrete and criti-
cal function in the operation of the electrical system.
However, the portion of the wiring that was replaced
is not a significant portion of the wiring major com-
ponent under paragraph (k)(6)(ii)(A) of this section,
nor does it comprise a substantial structural part of
the electrical system under paragraph (k)(6)(ii)(B) of
this section. Therefore, under paragraph (k)(6) of this
section, the replacement of 30 percent of the wiring
is not the replacement of a major component or sub-
stantial structural part of the building, and R is not re-
quired to treat the amount paid to replace 30 percent
of the wiring as a restoration to the building under
paragraph (k)(1)(iv) of this section.
Example 22.Replacement of major component
or substantial structural part
;plumbing system.S
owns a building in which it conducts a retail busi-
ness. The retail building has three floors. The re-
tail building has men’s and women’s restrooms on
two of the three floors. S decides to update the re-
strooms by paying an amount to replace the plumb-
ing fixtures in all of the restrooms, including all the
toilets and sinks, with modern style plumbing fixtures
of similar quality and function. S does not replace the
pipes connecting the fixtures to the building’s plumb-
ing system. Under paragraphs (e)(2)(ii) and (k)(2) of
this section, an amount is paid to improve a building
if the amount restores the building structure or any
building system. The plumbing system, including the
plumbing fixtures, is a building system under para-
graph (e)(2)(ii)(B)(
2) of this section. All the toilets
together perform a discrete and critical function in the
operation of the plumbing system, and all the sinks,
together, also perform a discrete and critical function
in the operation of the plumbing system. Therefore,
under paragraph (k)(6)(ii)(A) of this section, all the
toilets comprise a major component of the plumbing
system, and all the sinks comprise a major component
of the plumbing system. Accordingly, S must treat
the amount paid to replace all of the toilets and all of
the sinks as a restoration of the building under para-
graphs (k)(1)(vi) and (k)(2) of this section and must
capitalize the amount paid as an improvement to the
building under paragraph (d)(2) of this section.
Example 23.Not replacement of major compo-
nent or substantial structural part; plumbing system
.
Assume the same facts as
Example 22except that S
does not update all the bathroom fixtures. Instead,
Sonlypaysanamounttoreplace8ofthetotalof
20 sinks located in the various restrooms. The 8 re-
placed sinks, by themselves, do not comprise a sig-
nificant portion of a major component (the 20 sinks)
of the plumbing system under paragraph (k)(6)(ii)(A)
of this section nor do they comprise a large portion of
the physical structure of the plumbing system under
paragraph (k)(6)(ii)(B) of this section. Therefore, un-
der paragraph (k)(6) of thissection, the replacement
of the eight sinks does notconstitute the replacement
of a major component or substantial structural part of
the building, and S is not required to treat the amount
paid to replace the eight sinks as a restoration of a
building under paragraph (k)(1)(iv) of this section.
Example 24.Replacement of major component
or substantial structural part; plumbing system
.(i)T
owns and operates a hotel building. T decides that, to
attract customers and to remain competitive, it needs
to update the guest rooms in its facility. Accordingly,
T pays amounts to replace the bathtubs, toilets, and
sinks, and to repair, repaint, and retile the bathroom
walls and floors, which is necessitated by the installa-
tion of the new plumbing components. The replace-
ment bathtubs, toilets, sinks, and tile are new and in a
different style, but are similar in function and quality
to the replaced items. T also pays amounts to replace
certain section 1245 property, such as the guest room
furniture, carpeting, drapes, table lamps, and parti-
tion walls separating the bathroom area. T completes
this work on two floors at a time, closing those floors
and leaving the rest of the hotel open for business. In
Year 1, T pays amounts to perform the updates for 4
of the 20 hotel room floors and expects to complete
the renovation of the remaining rooms over the next
two years.
(ii) Under paragraphs (e)(2)(ii) and (k)(2) of this
section, an amount is paid to improve a building
if the amount restores the building structure or any
building system. The plumbing system, including
the bathtubs, toilets, and sinks, is a building system
under paragraph (e)(2)(ii)(B)(
2)ofthissection. All
the bathtubs, together, all the toilets, together, and
all the sinks together in the hotel building perform
discrete and critical functions in the operation of
the plumbing system under paragraph (k)(6)(ii)(A)
of this section and comprise a large portion of the
physical structure of the plumbing system under para-
graph (k)(6)(ii)(B) of this section. Therefore, under
paragraph (k)(6)(ii) of this section, these plumbing
components comprise major components and sub-
stantial structural parts of the plumbing system, and T
must treat the amount paid to replace these plumbing
components as a restoration of, and improvement to,
the building under paragraphs (k)(1)(vi) and (k)(2)
of this section. In addition, under paragraph (g)(1)(i)
of this section, T must treat the costs of repairing,
repainting, and retiling the bathroom walls and floors
as improvement costs because these costs directly
benefit and are incurred by reason of the improve-
ment to the building. Further, under paragraph (g)(3)
of this section, T must treat the costs incurred in
Years 1, 2, and 3 for the bathroom remodeling as
improvement costs, even though they are incurred
over a period of several taxable years, because they
are related amounts paid to improve the building unit
of property. Accordingly, under paragraph (d)(2) of
this section, T must treat all the amounts it incurs
to update its hotel restrooms as an improvement
to the hotel building and capitalize these amounts.
In addition, under §1.263(a)–2 of the regulations,
T must capitalize the amounts paid to acquire and
install each section 1245 property.
Example 25.Not replacement of major compo-
nent or substantial structural part; windows
.Uowns
a large office building that it uses to provide office
space for employees that manage U’s operations. The
building has 300 exterior windows that represent 25
percent of the total surface area of the building. In
Year 1, U pays an amount to replace 100 of the ex-
terior windows that had become damaged. At the
time of these replacements, U has no plans to replace
any other windows in the near future. Under para-
graphs (e)(2)(ii) and (k)(2) of this section, an amount
is paid to improve a building if the amount restores
the building structure or any building system. The
exterior windows are part of the building structure as
defined under paragraph (e)(2)(ii)(A) of this section.
The 300 exterior windows perform a discrete and crit-
ical function in the operation of the building structure
and are, therefore, a major component of the building
structure under paragraph (k)(6)(i)(A) of this section.
However, the 100 windows do not comprise a signif-
icant portion of this major component of the build-
ing structure under paragraph (k)(6)(ii)(A) of this sec-
tion or a substantial structural part of the building
structure under paragraph (k)(6)(ii)(B) of this section.
Therefore, under paragraph (k)(6) of this section, the
replacement of the 100 windows does not constitute
the replacement of a majorcomponent or substantial
structural part of the building, and U is not required to
treat the amount paid to replace the 100 windows as
restoration of the building under paragraph (k)(1)(iv)
of this section.
Example 26.Replacement of major component;
windows
. Assume the same facts asExample 25,
except that that U replaces 200 of the 300 windows
on the building. The 300 exterior windows perform
a discrete and critical function in the operation of
the building structure and are, therefore, a major
component of the building structure under paragraph
(k)(6)(i)(A) of this section. The 200 windows com-
prise a significant portion of this major component of
the building structure under paragraph (k)(6)(ii)(A)
of this section. Therefore, under paragraph (k)(6)
of this section, the replacement of the 200 windows
comprise the replacement of a major component of
the building structure. Accordingly, U must treat the
amount paid to replace the 200 windows as a restora-
tion of the building under paragraphs (k)(1)(vi) and
(k)(2) of this section and must capitalize the amount
paid as an improvement to the building under para-
graph (d)(2) of this section.
Example 27.Replacement of substantial struc-
tural part; windows
. Assume the same facts asEx-
ample 25,
except that the building is a modern de-
sign and the 300 windows represent 90 percent of the
2013–43 I.R.B.387October 21, 2013

total surface area of the building. U replaces 100
of the 300 windows on the building. The 300 ex-
terior windows perform a discrete and critical func-
tion in the operation of the building structure and are,
therefore, a major component of the building struc-
ture under paragraph (k)(6)(i)(A) of this section. The
100 windows do not comprise a significant portion of
this major component of the building structure under
paragraph (k)(6)(ii)(A) of this section, however, they
do comprise a substantial structural part of the build-
ing structure under paragraph (k)(6)(ii)(B) of this sec-
tion. Therefore, under paragraph (k)(6) of this sec-
tion, the replacement of the 100 windows comprise
the replacement of a substantial structural part of the
building structure. Accordingly, U must treat the
amount paid to replace the 100 windows as a restora-
tion of the building unit of property under paragraphs
(k)(1)(vi) and (k)(2) of this section and must capital-
ize the amount paid as an improvement to the building
under paragraph (d)(2) of this section.
Example 28.Not replacement of major compo-
nent or substantial structural part; floors
.Vowns
and operates a hotel building. V decides to refresh the
appearance of the hotel lobby by replacing the floors
in the lobby. The hotel lobby comprises less than 10
percent of the square footage of the entire hotel build-
ing. V pays an amount to replace the wood flooring in
the lobby with new wood flooring of a similar qual-
ity. V did not replace any other flooring in the build-
ing. Assume that the wood flooring constitutes sec-
tion 1250 property. Under paragraphs (e)(2)(ii) and
(k)(2) of this section, an amount is paid to improve a
building if the amount restores the building structure
or any building system. The wood flooring is part of
the building structure under paragraph (e)(2)(ii)(A) of
this section. All the floors in the hotel building com-
prise a major component of the building structure be-
cause they perform a discrete and critical function in
the operation of the building structure. However, the
lobby floors are not a significant portion of a major
component (that is, all the floors) under paragraph
(k)(6)(ii)(A) of this section, nor do the lobby floors
comprise a substantial structural part of the building
structure under paragraph (k)(6)(ii)(B) of this section.
Therefore, under paragraph (k)(6) of this section, the
replacement of the lobby floors is not the replacement
of a major component or substantial structural part of
the building unit of property, and V is not required to
treat the amount paid for the replacement of the lobby
floors as a restoration to the building under paragraph
(k)(1)(iv) of this section.
Example 29.Replacement of major component
or substantial structural part
;floors. Assume the
same facts as
Example 28, except that V decides to
refresh the appearance of all the public areas of the
hotel building by replacing all the floors in the pub-
lic areas. To that end, V pays an amount to replace
all the wood floors in all the public areas of the ho-
tel building with new wood floors. The public areas
include the lobby, the hallways, the meeting rooms,
the ballrooms, and other public rooms throughout the
hotel interiors. The public areas comprise approxi-
mately 40 percent of the square footage of the entire
hotel building. All the floors in the hotel building
comprise a major component of the building struc-
ture because they perform a discrete and critical func-
tion in the operation of the building structure. The
floors in all the public areas of the hotel comprise a
significant portion of a major component (that is, all
the building floors) of the building structure. There-
fore, under paragraph (k)(6)(ii)(A) of this section, the
replacement of all the public area floors constitutes
the replacement of a major component of the build-
ing structure. Accordingly, V must treat the amount
paid to replace the public area floors as a restora-
tion of the building unit of property under paragraphs
(k)(1)(vi) and (k)(2) of this section and must capital-
ize the amounts as an improvement to the building
under paragraph (d)(2) of this section.
Example 30.Replacement with no disposition.(i)
X owns an office building with four elevators serv-
ing all floors in the building. X replaces one of the
elevators. The elevator is astructural component of
the office building. X chooses to apply Prop. Reg.
§1.168(i)–8 to taxable years beginning on or after
January 1, 2012, and before the applicability date of
the final regulations. In accordance with Prop. Reg.
§1.168(i)–8(c)(4)(ii)(A) (September 19, 2013), the
office building (including its structural components)
is the asset for tax disposition purposes. X does not
treat the structural components of the office build-
ing as assets under Prop. Reg. §1.168(i)–8(c)(4)(iii)
(September 19, 2013). X also does not make the par-
tial disposition election provided under Prop. Reg.
§1.168(i)–8(d)(2) (September 19, 2013), for the ele-
vator. Thus, the retirement of the replaced elevator
is not a disposition under section 168, and no loss is
taken into account for purposes of paragraph (k)(1)(i)
of this section.
(ii) Under paragraphs (e)(2)(ii) and (k)(2) of this
section, an amount is paid to improve a building
if the amount restores the building structure or any
building system. The elevator system, including all
four elevators, is a building system under paragraph
(e)(2)(ii)(B)(
5) of this section. The replacement
elevator does not perform a discrete and critical
function in the operation of elevator system under
paragraph (k)(6)(ii)(A) of this section nor does it
comprise a large portion of the physical structure of
the elevator system under paragraph (k)(6)(ii)(B) of
this section. Therefore, under paragraph (k)(6) of this
section, the replacement elevator does not constitute
the replacement of a major component or substantial
structural part of the elevator system. Accordingly,
X is not required to treat the amount paid to replace
the elevator as a restoration to the building under
either paragraph (k)(1)(i) or paragraph (k)(1)(vi) of
this section.
Example 31.Replacement with disposition.The
facts are the same as in
Example 30,exceptXmakes
the partial disposition election provided under para-
graph Prop. Reg. §1.168(i)–8(d)(2) (September 19,
2013), for the elevator. Although the office building
(including its structural components) is the asset
for disposition purposes, the result of X making the
partial disposition election for the elevator is that the
retirement of the replaced elevator is a disposition.
Thus, depreciation for the retired elevator ceases at
the time of its retirement (taking into account the
applicable convention), and X recognizes a loss upon
this retirement. Accordingly, X must treat the amount
paid to replace the elevator as a restoration of the
building under paragraphs (k)(1)(i) and (k)(2) of this
section and must capitalize the amount paid as an im-
provement to the building under paragraph (d)(2) of
this section. In addition, the replacement elevator is
treated as a separate asset for tax disposition purposes
pursuant to Prop. Reg. §1.168(i)–8(c)(4)(ii)(D)
(September 19, 2013), and for depreciation purposes
pursuant to section 168(i)(6).
(l)Capitalization of amounts to adapt
property to a new or different use—(1)In
general. A taxpayer must capitalize as an
improvement an amount paid to adapt a
unit of property to a new or different use.
In general, an amount is paid to adapt a unit
of property to a new or different use if the
adaptation is not consistent with the tax-
payer’s ordinary use of the unit of property
at the time originally placed in service by
the taxpayer.
(2)Application of adaption rule to
buildings. In the case of a building, an
amount is paid to improve a building
if it is paid to adapt to a new or dif-
ferent use a property specified under
paragraph (e)(2)(ii) (building), paragraph
(e)(2)(iii)(B) (condominium), paragraph
(e)(2)(iv)(B) (cooperative), or paragraph
(e)(2)(v)(B) (leased building or leased
portion of building) of this section. For
example, an amount is paid to improve a
building if it is paid to adapt the building
structure or any one of its buildings sys-
tems to a new or different use.
(3)Examples. The following examples
illustrate the application of this paragraph
(l) only and do not address whether capital-
ization is required under another provision
of this section or under another provision
of the Code (for example, section 263A).
Unless otherwise stated, assume that the
taxpayer has not properly deducted a loss
for any unit of property, asset, or compo-
nent of a unit of property that is removed
and replaced.
Example 1.New or different use; change in build-
ing use
. A is a manufacturer and owns a manufactur-
ing building that it has used for manufacturing since
Year 1, when A placed it in service. In Year 30, A
pays an amount to convert its manufacturing building
into a showroom for its business. To convert the fa-
cility, A removes and replaces various structural com-
ponents to provide a better layout for the showroom
and its offices. A also repaints the building interi-
ors as part of the conversion. When building ma-
terials are removed and replaced, A uses compara-
ble and commercially available replacement materi-
als. Under paragraphs (l)(2) and (e)(2)(ii) of this sec-
tion, an amount is paid to improve A’s manufactur-
ing building if the amount adapts the building struc-
ture or any designated building system to a new or
different use. Under paragraph (l)(1) of this section,
the amount paid to convert the manufacturing build-
ing into a showroom adapts the building structure to
a new or different use because the conversion to a
showroom is not consistent with A’s ordinary use of
the building structure at the time it was placed in ser-
vice. Therefore, A must capitalize the amount paid to
convert the building into a showroom as an improve-

ment to the building under paragraphs (d)(3) and (l)
of this section.
Example 2.Not a new or different use; leased
building.
B owns and leases out space in a building
consisting of twenty retail spaces. The space was de-
signed to be reconfigured; that is, adjoining spaces
could be combined into one space. One of the tenants
expands its occupancy by leasing two adjoining retail
spaces. To facilitate the new lease, B pays an amount
to remove the walls between the three retail spaces.
Assume that the walls between spaces are part of the
building and its structural components. Under para-
graphs (l)(2) and (e)(2)(ii) of this section, an amount
is paid to improve B’s building if it adapts the build-
ing structure or any of the building systems to a new
or different use. Under paragraph (l)(1) of this sec-
tion, the amount paid to convert three retail spaces
into one larger space for an existing tenant does not
adapt B’s building structure to a new or different use
because the combination of retail spaces is consistent
with B’s intended, ordinary use of the building struc-
ture. Therefore, the amount paid by B to remove the
walls does not improve the building under paragraph
(l) of this section and is not required to be capitalized
under paragraph (d)(3) of this section.
Example 3.Not a new or different use; prepar-
ing building for sale
. C owns a building consisting of
twenty retail spaces. C decides to sell the building. In
anticipation of selling the building, C pays an amount
to repaint the interior walls and to refinish the hard-
wood floors. Under paragraphs (l)(2) and (e)(2)(ii) of
this section, an amount is paid to improve C’s build-
ing to a new or different use if it adapts the build-
ing structure or any of the building systems to a new
or different use. Preparing the building for sale does
not constitute a new or different use for the build-
ing structure under paragraph (l)(1) of this section.
Therefore, the amount paid by C to prepare the build-
ing structure for sale does not improve the building
under paragraph (l) of this section and is not required
to be capitalized under paragraph (d)(3) of this sec-
tion.
Example 4.New or different use; land.Downsa
parcel of land on which it previously operated a man-
ufacturing facility. Assume that the land is the unit
of property. During the course of D’s operation of
the manufacturing facility, the land became contami-
nated with wastes from its manufacturing processes.
D discontinues manufacturing operations at the site
and decides to develop the property for residential
housing. In anticipation of building residential prop-
erty, D pays an amount to remediate the contamina-
tion caused by D’s manufacturing process. In addi-
tion, D pays an amount to regrade the land so that it
can be used for residential purposes. Amounts that D
pays to clean up wastes do not adapt the land to a new
or different use, regardless of the extent to which the
land was cleaned, because this cleanup merely returns
the land to the condition it was in before the land was
contaminated in D’s operations. Therefore, D is not
required to capitalize the amount paid for the cleanup
under paragraph (l)(1) of this section. However, the
amount paid to regrade the land so that it can be used
for residential purposes adapts the land to a new or
different use that is inconsistent with D’s intended or-
dinary use of the property at the time it was placed in
service. Accordingly, the amounts paid to regrade the
land must be capitalized as improvements to the land
under paragraphs (d)(3) and (l) of this section.
Example 5.New or different use; part of build-
ing
. (i) E owns a building in which it operates a re-
tail drug store. The store consists of a pharmacy for
filling medication prescriptions and various depart-
ments where customers can purchase food, toiletries,
home goods, school supplies, cards, over-the-counter
medications, and other similar items. E decides to
create a walk-in medical clinic where nurse practi-
tioners and physicians’ assistants diagnose, treat, and
write prescriptions for common illnesses and injuries,
administer common vaccinations, conduct physicals
and wellness screenings, and provide routine lab tests
and services for common chronic conditions. To cre-
ate the clinic, E pays amounts to reconfigure the phar-
macy building. E incurs costs to build new walls
creating an examination room, lab room, reception
area, and waiting area. E installs additional plumb-
ing, electrical wiring, and outlets to support the lab. E
also acquires section 1245 property, such as comput-
ers, furniture, and equipment necessary for the new
clinic. E treats the amounts paid for those units of
property as costs of acquiring new units of property
under §1.263(a)–2.
(ii) Under paragraphs (l)(2) and (e)(2)(ii) of this
section, an amount is paid to improve E’s building if
it adapts the building structure or any of the building
systems to a new or different use. Under paragraph
(l)(1) of this section, the amount paid to convert part
of the retail drug store building structure into a med-
ical clinic adapts the building structure to a new and
different use, because the useof the building structure
to provide clinical medical services is not consistent
with E’s intended ordinary use of the building struc-
ture at the time it was placed in service. Similarly,
the amounts paid to add to the plumbing system and
the electrical systems to support the new medical ser-
vices is not consistent withE’s intended ordinary use
of these systems when the systems were placed in ser-
vice. Therefore, E must treat the amount paid for the
conversion of the building structure, plumbing sys-
tem, and electrical system as an improvement to the
building and capitalize the amount under paragraphs
(d)(3) and (l) of this section.
Example 6.Not a new or different use; part of
building.
(i) F owns a building in which it operates
a grocery store. The grocery store includes various
departments for fresh produce, frozen foods, fresh
meats, dairy products, toiletries, and over-the-counter
medicines. The grocery store also includes separate
counters for deli meats, prepared foods, and baked
goods, often made to order. To better accommodate
its customers’ shopping needs, F decides to add a
sushi bar where customers can order freshly prepared
sushi from the counter for take-home or to eat at the
counter. To create the sushi bar, F pays amounts to
add a sushi counter and chairs, add additional wiring
and outlets to support the counter, and install addi-
tional pipes and a sink, to provide for the safe han-
dling of the food. F also pays amounts to replace
flooring and wall coverings in the sushi bar area with
decorative coverings to reflect more appropriate dé-
cor. Assume the sushi counter and chairs are section
1245 property, and F treats the amounts paid for those
units of property as costs of acquiring new units of
property under §1.263(a)–2.
(ii) Under paragraphs (l)(2) and (e)(2)(ii) of this
section, an amount is paid to improve F’s building if
it adapts the building structure or any of the building
systems to a new or different use. Under paragraph
(l)(1) of this section, the amount paid to convert a
part of F’s retail grocery into a sushi bar area does
not adapt F’s building structure, plumbing system, or
electrical system to a new or different use, because
the sale of sushi is consistent with F’s intended, ordi-
nary use of the building structure and these systems
in its grocery sales business, which includes selling
food to its customers at various specialized counters.
Accordingly, the amount paid by F to replace the wall
and floor finishes, add wiring, and add plumbing to
create the sushi bar space does not improve the build-
ing unit of property under paragraph (l) of this section
and is not required to be capitalized under paragraph
(d)(3) of this section.
Example 7.Not a new or different use; part of
building
. (i) G owns a hospital with various depart-
ments dedicated to the provision of clinical medical
care. To better accommodate its patients’ needs, G
decides to modify the emergency room space to pro-
vide both emergency care and outpatient surgery. To
modify the space, G pays amounts to move interior
walls, add additional wiring and outlets, replace floor
tiles and doors, and repaint the walls. To complete the
outpatient surgery center, G also pays amounts to in-
stall miscellaneous medical equipment necessary for
the provision of surgicalservices. Assume the med-
ical equipment is section 1245 property, and G treats
the amounts paid for those units of property as costs
of acquiring new units of property under §1.263(a)–2.
(ii) Under paragraphs (l)(2) and (e)(2)(ii) of this
section, an amount is paid to improve G’s building
if it adapts the building structure or any of the build-
ing systems to a new or different use. Under para-
graph (l)(1) of this section, the amount paid to con-
vert part of G’s emergency room into an outpatient
surgery center does not adapt G’s building structure
or electrical system to a new or different use, because
the provision of outpatient surgery is consistent with
G’s intended, ordinary use of the building structure
and these systems in its clinical medical care busi-
ness. Accordingly, the amounts paid by G to relocate
interior walls, add additional wiring and outlets, re-
place floor tiles and doors, and repaint the walls to
create outpatient surgery space do not improve the
building under paragraph (l) of this section and are
not required to be capitalized under paragraph (d)(3)
of this section.
(m)Optional regulatory accounting
method—(1)In general. This para-
graph (m) provides an optional simpli-
fied method (the regulatory accounting
method) for regulated taxpayers to de-
termine whether amounts paid to repair,
maintain, or improve tangible property
are to be treated as deductible expenses
or capital expenditures. A taxpayer that
uses the regulatory accounting method de-
scribed in paragraph (m)(3) of this section
must use that method for property subject
to regulatory accounting instead of deter-
mining whether amounts paid to repair,
maintain, or improve property are capi-
tal expenditures or deductible expenses
under the general principles of sections
162(a), 212, and 263(a). Thus, the capi-
2013–43 I.R.B.389October 21, 2013

talization rules in paragraph (d) (and the
routine maintenancesafe harbor described
in paragraph (i)) of this section do not
apply to amounts paid to repair, maintain,
or improve property subject to regula-
tory accounting by taxpayers that use the
regulatory accounting method under this
paragraph (m).
(2)Eligibility for regulatory account-
ing method. A taxpayer that is engaged
in a trade or business in a regulated in-
dustry is a regulated taxpayer and may
use the regulatory accounting method un-
der this paragraph (m). For purposes of
this paragraph (m), a taxpayer is in a reg-
ulated industry only if the taxpayer is sub-
ject to the regulatory accounting rules of
the Federal Energy Regulatory Commis-
sion (FERC), the Federal Communications
Commission (FCC), or the Surface Trans-
portation Board (STB).
(3)Description of regulatory account-
ing method. Under the regulatory ac-
counting method, a taxpayer must follow
the method of accounting for regulatory
accounting purposes that it is required to
follow for FERC, FCC, or STB (whichever
is applicable) in determining whether an
amount paid repairs, maintains, or im-
proves property under this section. There-
fore, a taxpayer must capitalize for Federal
income tax purposes an amount paid that
is capitalized as an improvement for reg-
ulatory accounting purposes. A taxpayer
may not capitalize for Federal income tax
purposes under this section an amount
paid that is not capitalized as an improve-
ment for regulatory accounting purposes.
A taxpayer that uses the regulatory ac-
counting method must use that method for
all of its tangible property that is subject to
regulatory accounting rules. The method
does not apply to tangible property that
is not subject to regulatory accounting
rules. The method also does not apply to
property for the taxable years in which
the taxpayer elected to apply the repair
allowance under §1.167(a)–11(d)(2). The
regulatory accounting method is a method
of accounting under section 446(a).
(4)Examples. The following examples
illustrate the application of this paragraph
(m):
Example 1.Taxpayer subject to regulatory ac-
counting rules of FERC
. W is an electric utility com-
pany that operates a power plant that generates elec-
tricity and that owns and operates network assets to
transmit and distribute the electricity to its customers.
W is subject to the regulatory accounting rules of
FERC, and W uses the regulatory accounting method
under paragraph (m) of this section. W does not capi-
talize on its books and records for regulatory account-
ing purposes the cost of repairs and maintenance per-
formed on its turbines or its network assets. Under
the regulatory accounting method, W may not capi-
talize for Federal income tax purposes amounts paid
for repairs performed on its turbines or its network
assets.
Example 2.Taxpayer not subject to regulatory ac-
counting rules of FERC
. X is an electric utility com-
pany that operates a power plant to generate electric-
ity. X previously was subject to the regulatory ac-
counting rules of FERC, but currently X is not re-
quired to use FERC’s regulatory accounting rules.
X cannot use the regulatoryaccountingmethodpro-
vided in this paragraph (m).
Example 3.Taxpayer subject to regulatory ac-
counting rules of FCC
. Y is a telecommunications
company that is subject to the regulatory accounting
rules of the FCC. Y uses the regulatory accounting
method under this paragraph (m). Y’s assets include
a telephone central office switching center, which
contains numerous switches and various switching
equipment. Y capitalizes on its books and records for
regulatory accounting purposes the cost of replac-
ing each switch. Under the regulatory accounting
method, Y is required to capitalize for Federal in-
come tax purposes amounts paid to replace each
switch.
Example 4.Taxpayer subject to regulatory ac-
counting rules of STB
. Z is a Class I railroad that
is subject to the regulatory accounting rules of the
STB. Z uses the regulatory accounting method un-
der this paragraph (m). Z capitalizes on its books and
records for regulatory accounting purposes the cost of
locomotive rebuilds. Under the regulatory account-
ing method, Z is required to capitalize for Federal in-
come tax purposes amounts paid to rebuild its loco-
motives.
(n)Election to capitalize repair and
maintenance costs—(1)In general.A
taxpayer may elect to treat amounts paid
during the taxable year for repair and
maintenance (as defined under §1.162–4)
to tangible property as amounts paid to
improve that property under this section
and as an asset subject to the allowance for
depreciation if the taxpayer incurs these
amounts in carrying on the taxpayer’s
trade or business and if the taxpayer treats
these amounts as capital expenditures on
its books and records regularly used in
computing income (“books and records”).
A taxpayer that elects to apply this para-
graph (n) in a taxable year must apply
this paragraph to all amounts paid for re-
pair and maintenance to tangible property
that it treats as capital expenditures on its
books and records in that taxable year.
Any amounts for which this election is
made shall not be treated as amounts paid
for repair or maintenance under §1.162–4.
(2)Time and manner of election.A
taxpayer makes this election under this
paragraph (n) by attaching a statement to
the taxpayer’s timely filed original Federal
tax return (including extensions) for the
taxable year in which the taxpayer pays
amounts described under paragraph (n)(1)
of this paragraph. See §§301.9100–1
through 301.9100–3 of this chapter for the
provisions governing extensions of time
to make regulatory elections. The state-
ment must be titled “Section 1.263(a)–3(n)
Election” and include the taxpayer’s name,
address, taxpayer identification number,
and a statement that the taxpayer is making
the election to capitalize repair and main-
tenance costs under §1.263(a)–3(n). In the
case of a consolidated group filing a con-
solidated income tax return, the election
is made for each member of the consoli-
dated group by the common parent, and
the statement must also include the names
and taxpayer identification numbers of
each member for which the election is
made. In the case of an S corporation or a
partnership, the election is made by the S
corporation or partnership and not by the
shareholders or partners. A taxpayer mak-
ing this election for a taxable year must
treat any amounts paid for repairs and
maintenance during the taxable year that
are capitalized on the taxpayer’s books
and records as improvements to tangible
property. The taxpayer must begin to de-
preciate the cost of such improvements
amounts when they are placed in service
by the taxpayer under the applicable pro-
visions of the Code and regulations. An
election may not be made through the
filing of an application for change in ac-
counting method or, before obtaining the
Commissioner’s consent to make a late
election, by filing an amended Federal tax
return. The time and manner of electing
to capitalize repair and maintenance costs
under this paragraph (n) may be modified
through guidance of general applicability
(see §§601.601(d)(2) and 601.602 of this
chapter).
(3)Exception. This paragraph (n) does
not apply to amounts paid for repairs
or maintenance of rotable or temporary
spare parts to which the taxpayer applies
the optional method of accounting for
rotable and temporary spare parts under
§1.162–3(e).
October 21, 20133902013–43 I.R.B.

(4)Examples. The following examples
illustrate the application of this paragraph
(n):
Example 1.Election to capitalize routine main-
tenance on non-rotable part
.(i)Qisatowboatop-
erator that owns a fleet of towboats that it uses in
its trade or business. Each towboat is equipped with
two diesel-powered engines. Assume that each tow-
boat, including its engines, is the unit of property and
that a towboat has a class life of 18 years. Assume
the towboat engines are not rotable spare parts under
§1.162–3(c)(2). In Year 1, Q acquired a new towboat,
including its two engines, and placed the towboat into
service. In Year 4, Q pays amounts to perform sched-
uled maintenance on both engines in the towboat. As-
sume that none of the exceptions set out in paragraph
(i)(3) of this section apply to the scheduled mainte-
nance costs and that the scheduled maintenance on
Q’s towboat is within the routine maintenance safe
harbor under paragraph (i)(1)(ii) of this section. Ac-
cordingly, the amounts paid for the scheduled main-
tenance to its towboat engines in Year 4 are deemed
not to improve the towboat and are not required to be
capitalized under paragraph (d) of this section.
(ii) On its books and records, Q treats amounts
paid for scheduled maintenance on its towboat en-
gines as capital expenditures. For administrative con-
venience, Q decides to account for these costs in the
same way for Federal income tax purposes. Under
paragraph (n) of this section, in Year 4, Q may elect
to capitalize the amounts paid for the scheduled main-
tenance on its towboat engines. If Q elects to capital-
ize such amounts, Q must capitalize all amounts paid
for repair and maintenance to tangible property that Q
treats as capital expenditures on its books and records
in Year 4.
Example 2.No election to capitalize routine
maintenance
. Assume the same facts asExample
1
, except in Year 8, Q pays amounts to perform
scheduled maintenance for a second time on the
towboat engines. On its books and records, Q treats
the amounts paid for this scheduled maintenance as
capital expenditures. However, in Year 8, Q decides
not to make the election to capitalize the amounts
paid for scheduled maintenance under paragraph
(n) of this section. Because Q does not make the
election under paragraph (n) for Year 8, Q may apply
the routine maintenance safe harbor under paragraph
(i)(1)(ii) of this section to the amounts paid in Year 8,
and not treat these amounts as capital expenditures.
Because the election is made for each taxable year,
there is no effect on the scheduled maintenance costs
capitalized by Q on its Federal tax return for Year 4.
Example 3.Election to capitalize replacement of
building component
. (i) R owns an office building
that it uses to provide services to customers. The
building contains a HVAC system that incorporates
ten roof-mounted units that provide heating and air
conditioning for different parts of the building. In
Year 1, R pays an amount to replace 2 of the 10 units
to address climate control problems in various offices
throughout the office building. Assume that the re-
placement of the two units does not constitute an im-
provement to the HVAC system, and, accordingly, to
the building unit of property under paragraph (d) of
this section, and that R may deduct these amounts as
repairs and maintenance under §1.162–4.
(ii) On its books and records, R treats amounts
paid for the two HVAC components as capital expen-
ditures. R determines that it would prefer to account
for these amounts in the same way for Federal in-
come tax purposes. Under this paragraph (n), in Year
1, R may elect to capitalize the amounts paid for the
new HVAC components. If R elects to capitalize such
amounts, R must capitalize all amounts paid for repair
and maintenance to tangible property that R treats as
capital expenditures on its books and records in Year
1.
(o)Treatment of capital expenditures.
Amounts required to be capitalized un-
der this section are capital expenditures
and must be taken into account through a
charge to capital account or basis, or in the
case of property that is inventory in the
hands of a taxpayer, through inclusion in
inventory costs.
(p)Recovery of capitalized amounts.
Amounts that are capitalized under this
section are recovered through deprecia-
tion, cost of goods sold, or by an adjust-
ment to basis at the time the property is
placed in service, sold, used, or otherwise
disposed of by the taxpayer. Cost recovery
is determined by the applicable Code and
regulation provisions relating to the use,
sale, or disposition of property.
(q)Accounting method changes.Ex-
cept as otherwise provided in this section,
a change to comply with this section is a
change in method ofaccounting to which
the provisions of sections 446 and 481 and
the accompanying regulations apply. A
taxpayer seeking to change to a method of
accounting permitted in this section must
secure the consent of the Commissioner in
accordance with §1.446–1(e) and follow
the administrative procedures issued under
§1.446–1(e)(3)(ii) for obtaining the Com-
missioner’s consent to change its account-
ing method.
(r)Effective/applicability date—(1)In
general. Except for paragraphs (h), (m),
and (n) of this section, this section ap-
plies to taxable years beginning on or af-
ter January 1, 2014. Paragraphs (h), (m),
and(n)ofthissectionapplytoamounts
paid in taxable years beginning on or af-
ter January 1, 2014. Except as provided in
paragraphs (r)(2) and (r)(3) of this section,
§1.263(a)–3 as contained in 26 CFR part 1
edition revised as of April 1, 2011, applies
to taxable years beginning before January
1, 2014.
(2)Early application of this sec-
tion—(i)In general. Except for para-
graphs (h), (m), and (n) of this section, a
taxpayer may choose to apply this section
to taxable years beginning on or after Jan-
uary 1, 2012. A taxpayer may choose to
apply paragraphs (h), (m), and (n) of this
section to amounts paid in taxable years
beginning on or after January 1, 2012.
(ii)Transition rule for certain elections
on 2012 or 2013 returns.Ifunderpara-
graph (r)(2)(i) of this section, a taxpayer
chooses to make the election to apply the
safe harbor for small taxpayers under para-
graph (h) of this section or the election
to capitalize repair and maintenance costs
under paragraph (n) of this section for
amounts paid in its taxable year beginning
on or after January 1, 2012, and ending on
or before September 19, 2013 (applicable
taxable year), and the taxpayer did not
make the election specified in paragraph
(h)(6) or paragraph (n)(2) of this section
on its timely filed original Federal tax
return for the applicable taxable year, the
taxpayer must make the election specified
in paragraph (h)(6) or paragraph (n)(2) of
this section for the applicable taxable year
by filing an amended Federal tax return
(including the required statements) for the
applicable taxable year on or before 180
days from the due date including exten-
sions of the taxpayer’s Federal tax return
for the applicable taxable year, notwith-
standing that the taxpayer may not have
extended the due date.
(3)Optional application of TD
9564. A taxpayer may choose to apply
§1.263(a)–3T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2012, and before January 1, 2014.
§1.263(a)–3T [Removed]
Par. 25. Section 1.263(a)–3T is re-

moved.
Par. 31. Section 1.1016–3 is amended
by revising paragraphs (a)(1)(ii), (j)(1),
and (j)(3) to read as follows:
§1.1016–3 Exhaustion, wear and tear,
obsolescence, amortization, and depletion
for periods since February 13, 1913.
(a)***
(1)* * *
(ii) The determination of the amount
properly allowable for exhaustion, wear
and tear, obsolescence, amortization, and
depletion must be made on the basis of
facts reasonably known to exist at the end
of the taxable year. A taxpayer is not
permitted to take advantage in a later year
of the taxpayer’s prior failure to take any
such allowance or the taxpayer’s taking
an allowance plainly inadequate under
the known facts in prior years. In the
case of depreciation, if in prior years the
taxpayer has consistently taken proper
deductions under one method, the amount
allowable for such prior years may not be
increased, even though a greater amount
would have been allowable under another
proper method. For rules governing losses
on retirement or disposition of depreciable
property, including rules for determining
basis, see §1.167(a)–8, §1.168(i)–1T(e),
§1.168(i)–8T, Prop. Reg. §1.168(i)–1(e)
(September 19, 2013), or Prop. Reg.
§1.168(i)–8 (September 19, 2013), as ap-
plicable. The application of this paragraph
is illustrated by the following example (for
purposes of this example, assume section
167(f)(1) as in effect on September 19,
2013, applies to taxable years beginning
on or after January 1, 2014):
Example. On July 1, 2014, A, a calendar-year tax-
payer, purchased and placedin service “off-the-shelf”
computer software at a cost of $36,000. This com-
puter software is not an amortizable section 197
intangible. Pursuant to section 167(f)(1), the useful
life of the computer software is 36 months. It has no
salvage value. Computer software placed in service
in 2014 is not eligible for the additional first year
depreciation deduction provided by section 168(k).
A did not deduct any depreciation for the computer
software for 2014 and deducted depreciation of
$12,000 for the computer software for 2015. As a
result, the total amount of depreciation allowed for
the computer software as of December 31, 2015, was
$12,000. However, the total amount of depreciation
allowable for the computer software as of December
31, 2015, is $18,000 ($6,000 for 2014 + $12,000 for
2015). As a result, the unrecovered cost of the com-
puter software as of December 31, 2015, is $18,000
(cost of $36,000 less the depreciation allowable of
$18,000 as of December 31, 2015). Accordingly,
depreciation for 2016 for the computer software is
$12,000 (unrecovered cost of $18,000 divided by the
remaining useful life of 18 months as of January 1,
2016, multiplied by 12 full months in 2016).

Part III. Administrative, Procedural, and Miscellaneous
26 CFR 601.105: Examination of returns and claims
for refund, credit, or abatement; determination of
correct liability.
(Also: sections 66, 6015)
Rev. Proc. 2013–34
SECTION 1. PURPOSE AND SCOPE
.01Purpose. This revenue procedure
provides guidance for a taxpayer seeking
equitable relief from income tax liability
under section 66(c) or section 6015(f) of
the Internal Revenue Code (a “requesting
spouse”). Section 4.01 of this revenue
procedure provides the threshold require-
ments for any request for equitable relief.
Section 4.02 of this revenue procedure sets
forth the conditions under which the In-
ternal Revenue Service will make stream-
lined relief determinations granting equi-
table relief under section 6015(f) from an
understatement of income tax or an un-
derpayment of income tax reported on a
joint return, or the operation of community
property law under section 66(c). Section
4.03 of this revenue procedure provides a
nonexclusive list of factors for considera-
tion in determining whether relief should
be granted under section 6015(f) because it
would be inequitable to hold a requesting
spouse jointly and severally liable when
the conditions of section 4.02 are not met.
The factors in section 4.03 also will apply
in determining whether to relieve a spouse
from income tax liability resulting from
the operation of community property law
under the equitable relief provision of sec-
tion 66(c).
.02Scope. This revenue procedure ap-
plies to spouses who request either equi-
table relief from jointand several liability
under section 6015(f), or equitable relief
under section 66(c) from income tax lia-
bility resulting from the operation of com-
munity property law.
SECTION 2. BACKGROUND
.01 Section 6013(d)(3) provides that
married taxpayers who file a joint return
under section 6013 will be jointly and
severally liable for the income tax arising
from that joint return. For purposes of
section 6013(d)(3) and this revenue pro-
cedure, the term “tax” includes penalties,
additions to tax, and interest. See sections
6601(e)(1) and 6665(a)(2).
.02 Section 3201(a) of the Internal Rev-
enue Service Restructuring and Reform
Act of 1998, Pub. L. No. 105–206, 112
Stat. 685, 734 (RRA), enacted section
6015, which provides relief in certain
circumstances from the joint and several
liability imposed by section 6013(d)(3).
Section 6015(b) and (c) specify two sets
of circumstances under which relief from
joint and several liability is available in
cases involving understatements of tax.
Section 6015(b) is modeled after former
section 6013(e), the prior innocent spouse
statute, and section 6015(c) provides for
separation of liability for taxpayers who
are no longer married to, are legally sepa-
rated from, or not living together with the
person with whom they filed a joint re-
turn. If relief is not available under section
6015(b) or (c), section 6015(f) authorizes
the Secretary to grant equitable relief if,
taking into account all the facts and cir-
cumstances, the Secretary determines that
it is inequitable to hold a requesting spouse
liable for any unpaid tax or any deficiency
(or any portion of either).
Section 66(c) provides relief from in-
come tax liability resulting from the op-
eration of community property law to tax-
payers domiciled in a community property
state who do not file a joint return. Sec-
tion 3201(b) of the RRA amended section
66(c) to add an equitable relief provision
similar to section 6015(f).
.03 Section 6015 provides relief only
from joint and several liability arising from
a joint return. If an individual signs a joint
return under duress, the election to file
jointly is not valid and there is no valid re-
turn with respect to the requesting spouse.
The individual is not jointly and severally
liable for any income tax liabilities aris-
ing from that return. In that case, section
6015 does not apply and is not necessary
for obtaining relief. If an individual files
a claim for relief under section 6015, but
also maintains that there is no valid joint
return due to duress, the Service will first
make a determination as to the validity of
the joint return and may accordingly deny
the request for section 6015 relief based on
the fact that no joint return was filed (and
thus, relief is not necessary). If it is ulti-
mately determined that a valid joint return
was filed, the Service will then consider
whether the individual would be entitled to
relief from joint and several liability on the
merits.
.04 Under section 6015(b) and (c), re-
lief is available only from an understate-
ment or a deficiency. Section 6015(b) and
(c) do not authorize relief from an under-
payment of income tax reported on a joint
return. Section 66(c)and section 6015(f)
permit equitable relief from an underpay-
ment of income tax or from a deficiency.
The legislative history of section 6015 pro-
vides that Congress intended for the Secre-
tary to exercise discretion in granting eq-
uitable relief from an underpayment of in-
come tax if a requesting spouse “does not
know, and had no reason to know, that
funds intended for the payment of tax were
instead taken by the other spouse for such
other spouse’s benefit.” H.R. Conf. Rep.
No. 105–599, at 254 (1998). Congress
also intended for the Secretary to exercise
the equitable relief authority under section
6015(f) in other situations if, “taking into
account all the facts and circumstances, it
is inequitable to hold an individual liable
for all or part of any unpaid tax or defi-

On January 5, 2012,the Department
of Treasury and the Service released No-
tice 2012–8, 2012–4 I.R.B. 309, which
set forth a proposed revenue procedure to
update and revise Rev. Proc. 2003–61,
2003–2 C.B. 296. Notice 2012–8 also
modified and clarified the criteria for equi-
table relief, and it eliminated the two-year
rule for filing a claim for relief as set forth
in Notice 2011–70, 2011–32 I.R.B. 135.
Notice 2012–8 invited public comment re-
garding the proposed revenue procedure.
A total of 54 comments were received, 45
of which were generalcomments either in
support of the revisions, asking for assis-
tance in specific cases, or totally unrelated
to innocent spouse relief. The nine sub-
stantive comments ranged from discussing
one or two discrete issues to commenting
on all aspects of the proposed revenue pro-
cedure and innocent spouse relief in gen-
eral. Treasury and the Service considered
all comments received, and the proposed
revenue procedure has been modified to
2013–43 I.R.B.397October 21, 2013

take into account many of the concerns
raised.
This revenue procedure supersedes
Rev. Proc. 2003–61. The structure and
format of this revenue procedure generally
follows that of Rev. Proc. 2003–61 with
the following significant changes:
.01 This revenue procedure gives
greater deference to the presence of abuse
than Rev. Proc. 2003–61. The Service
recognizes that the issue of abuse can be
relevant with respect to the analysis of
other factors and can negate the presence
of certain factors. This change is intended
to give greater weight to the presence of
abuse when its presence impacts the anal-
ysis of other factors.
.02 The timeliness threshold condition
in section 4.01(3) of this revenue proce-
dure provides that a request for equitable
relief under section 6015(f) or section
66(c) must be filed before the expiration of
the period of limitation for collection un-
der section 6502 to the extent the taxpayer
seeks relief from an outstanding liability,
or before the expiration of the period of
limitation for credit or refund under sec-
tion 6511 to the extent the taxpayer seeks
a refund of taxes paid. This is a significant
change to the requirement in Rev. Proc.
2003–61, section 4.01(3), and Treas. Reg.
§ 1.6015–5(b)(1) (TD 9003), that the re-
questing spouse’s claim for equitable relief
must be filed no later than two years after
the date of the Service’s first collection
activity.SeeNotice 2011–70. In response
to a comment received with respect to
Notice 2012–8, section 4.01(3)(a) refers
to the period of limitation for collection as
its commonly used IRS term — Collection
Statute Expiration Date or CSED.
.03 The attribution threshold condition
in section 4.01(7) of this revenue proce-
dure adds a new exception in paragraph (e)
to the requirement that the income tax li-
ability must be attributable to an item of
the nonrequesting spouse. Under section
4.01(7)(e) of the revenue procedure, relief
would not be precluded for an item attrib-
utable to the requesting spouse if the non-
requesting spouse’s fraud gave rise to the
understatement of tax or deficiency.
.04 Streamlined determinations under
section 4.02 of this revenue procedure now
apply to understatements of income tax in-
stead of only underpayments as under Rev.
Proc. 2003–61. Section 4.02 also now ap-
plies to claims for equitable relief under
section 66(c).
.05 Section 4.03(2) of this revenue pro-
cedure clarifies that no one factor or a ma-
jority of factors necessarily controls the
determination. Therefore, depending on
the facts and circumstances of the case, re-
lief may still be appropriate if the number
of factors weighing against relief exceeds
the number of factors weighing in favor of
relief, or a denial of relief may still be ap-
propriate if the number of factors weigh-
ing in favor of relief exceeds the number
of factors weighing against relief.
.06 The economic hardship factor in
section 4.03(2)(b) of this revenue proce-
dure now provides minimum standards
based on income, expenses, and assets,
for determining whether the requesting
spouse would suffer economic hardship if
relief is not granted. Section 4.03(2)(b)
also now provides that the lack of a find-
ing of economic hardship does not weigh
against relief, as it did under Rev. Proc.
2003–61, and instead will be neutral.
.07 The knowledge factor for under-
statement cases in section 4.03(2)(c)(i)
of this revenue procedure clarifies how
the factor works in cases involving equi-
table relief under section 66(c), in addition
to cases involving equitable relief under
section 6015(f). Section 4.03(2)(c)(i)(A)
provides that actualknowledge of the item
giving rise to an understatement or defi-
ciency will no longer be weighed more
heavily than other factors, as it did under
Rev. Proc. 2003–61. Further, section
4.03(2)(c)(i)(A) clarifies that, for purposes
of this factor, if the nonrequesting spouse
abused the requesting spouse or main-
tained control over the household finances
by restricting the requesting spouse’s ac-
cess to financial information, and because
of the abuse or financial control, the re-
questing spouse was not able to challenge
the treatment of any items on the joint re-
turn for fear of the nonrequesting spouse’s
retaliation, then that abuse or financial
control will result in this factor weighing
in favor of relief even if the requesting
spouse knew or had reason to know of the
items giving rise to the understatement or
deficiency.
.08 The knowledge factor for under-
payment cases in section 4.03(2)(c)(ii) of
this revenue procedure now provides that,
in determining whether the requesting
spouse knew or had reason to know that
the nonrequesting spouse would not pay
the tax reported as due on the return, the
Service will consider whether the request-
ing spouse reasonably expected that the
nonrequesting spouse would pay the tax
liability at the time the return was filed or
within a reasonable period of time after
the filing of the return. In response to
comments received with respect to Notice
2012–8, section 4.03(2)(c)(ii) provides
that a requesting spouse may be presumed
to have reasonably expected that the non-
requesting spouse would pay the liability
if a request for an installment agreement
topaythetaxwasfiledbythelaterof
90 days after the due date for payment
of the tax, or 90 days after the return
was filed. Further, section 4.03(2)(c)(ii)
clarifies that for purposes of this factor,
if the nonrequesting spouse abused the
requesting spouse or maintained control
over the household finances by restricting
the requesting spouse’s access to financial
information, and because of the abuse or
financial control, the requesting spouse
was not able to question the payment of
the taxes reported as due on the return or
challenge the nonrequesting spouse’s as-
surance regarding payment of the taxes for
fear of the nonrequesting spouse’s retali-
ation, then that abuse or financial control
will result in this factor weighing in fa-
vor of relief even if the requesting spouse
knew or had reason to know that the non-
requesting spouse would not pay the tax
liability. Finally, section 4.03(2)(c)(ii)
provides that if the requesting spouse did
not reasonably expect that the nonrequest-
ing spouse would pay the tax liability
reported on an amended return that was
based on items not properly reported on
the original return, the Service will also
consider whether the requesting spouse
knew or had reason to know of the under-
statement on the original return.
.09 The legal obligation factor in sec-
tion 4.03(2)(d) of this revenue procedure
clarifies that a requesting spouse’s legal
obligation to pay outstanding tax liabili-
ties is a factor to consider in determining
whether equitable relief should be granted,
in addition to whether the nonrequesting
spouse has a legal obligation to pay the tax
liabilities.
.10 The significant benefit factor in sec-
tion 4.03(2)(e) of this revenue procedure
provides that any significant benefit a re-
questing spouse may have received from
October 21, 20133982013–43 I.R.B.

the unpaid tax or understatement will not
weigh against relief (will be neutral) if the
nonrequesting spouse abused the request-
ing spouse or maintained financial control
and made the decisions regarding living
a more lavish lifestyle. Further, section
4.03(2)(e) provides that if only the non-
requesting spouse significantly benefitted
from the unpaid tax or understatement, and
the requesting spouse had little or no ben-
efit, or the nonrequesting spouse enjoyed
the benefit to the requesting spouse’s detri-
ment, this factor will weigh in favor of
relief. Section 4.03(2)(e) also provides
that if the amount of unpaid tax or under-
statement of tax was small such that nei-
ther spouse received a significant benefit,
then this factor is neutral. In response to
comments received with respect to Notice
2012–8, section 4.03(2)(e) provides that
the determination that the tax liability was
small such that neither spouse received a
significant benefit will vary depending on
the facts and circumstances of each case.
.11 The compliance with the income tax
laws factor in section 4.03(2)(f) of this rev-
enue procedure now provides that a re-
questing spouse’s subsequent compliance
with all Federal income tax laws is a factor
that may weigh in favor of relief, instead
of always being neutral under Rev. Proc.
2003–61.
.12 Section 4.04 of this revenue proce-
dure broadens the availability of refunds in
cases involving deficiencies by eliminat-
ing the rule in section 4.04(1) of Rev. Proc.
2003–61 that limited refunds in cases in-
volving deficiencies to payments made by
the requesting spouse pursuant to an in-
stallment agreement.
SECTION 4. GENERAL CONDITIONS
FOR RELIEF
.01Eligibility for equitable relief.A
requesting spouse must satisfy all of the
following threshold conditions to be eli-
gible to submit a request for equitable re-
lief under section 6015(f). With the excep-
tion of conditions (1) and (2), a request-
ing spouse must satisfy all of the follow-
ing threshold conditions to be eligible to
submit a request for equitable relief under
section 66(c). The Service may relieve a
requesting spouse who satisfies all the ap-
plicable threshold conditions set forth be-
low of all or part of the income tax liabil-
ity under section 66(c) or section 6015(f)
if, taking into accountall the facts and cir-
cumstances, the Service determines that it
would be inequitable to hold the requesting
spouse liable for the income tax liability.
The threshold conditions are as follows:
(1) The requesting spouse filed a joint
return for the taxable year for which he or
she seeks relief.
(2) Relief is not available to the request-
ing spouse under section 6015(b) or (c).
(3) The claim for relief is timely filed:
(a) If the requesting spouse is applying
for relief from a liability or a portion of a li-
ability that remains unpaid, the request for
relief must be made on or before the Col-
lection Statute Expiration Date (CSED).
The CSED is the date the period of limi-
tation on collection of the income tax lia-
bility expires, as provided in section 6502.
Generally, that period expires 10 years af-
ter the assessment of tax, but it may be ex-
tended by other provisions of the Internal
Revenue Code.
(b) Claims for credit or refund of
amounts paid must be made before the
expiration of the period of limitation on
credit or refund, as provided in section
6511. Generally, that period expires three
years from the time the return was filed or
two years from the time the tax was paid,
whichever is later.
(4) No assets were transferred between
the spouses as part of a fraudulent scheme
by the spouses.
(5) The nonrequesting spouse did not
transfer disqualified assets to the request-
ing spouse. For this purpose, the term “dis-
qualified asset” has the meaning given the
term by section 6015(c)(4)(B). If the non-
requesting spouse transferred disqualified
assets to the requesting spouse, relief will
be available only to the extent that the in-
come tax liability exceeds the value of the
disqualified assets. Even if there was a
transfer of disqualified assets, the request-
ing spouse may be eligible for relief if the
nonrequesting spouse abused the request-
ing spouse or maintained control over the
household finances by restricting the re-
questing spouse’s access to financial in-
formation, or the requesting spouse did
not have actual knowledge that disquali-
fied assets were transferred.
(6) The requesting spouse did not
knowingly participate in the filing of a
fraudulent joint return.
(7) The income tax liability from which
the requesting spouse seeks relief is attrib-
utable (either in full or in part) to an item
of the nonrequesting spouse or an under-
payment resulting from the nonrequesting
spouse’s income. If the liability is partially
attributable to the requesting spouse, then
relief can only be considered for the por-
tion of the liability attributable to the non-
requesting spouse. Nonetheless, the Ser-
vice will consider granting relief regard-
less of whether the understatement, defi-
ciency, or underpayment is attributable (in
full or in part) to the requesting spouse if
any of the following exceptions applies:
(a)Attribution solely due to the oper-
ation of community property law.Ifan
item is attributable or partially attribut-
able to the requesting spouse solely due to
the operation of community property law,
then for purposes of this revenue proce-
dure, that item (or portion thereof) will be
considered to be attributable to the nonre-
questing spouse.
(b)Nominal ownership.Iftheitemis
titled in the name of the requesting spouse,
the item is presumptively attributable to
the requesting spouse. This presumption
is rebuttable. For example, H opens an in-
dividual retirement account (IRA) in W’s
name and forges W’s signature on the IRA
in 2006. Thereafter, H makes contribu-
tions to the IRA and in 2008 takes a tax-
able distribution from the IRA. H and W
file a joint return for the 2008 taxable year,
but do not report the taxable distribution
on their joint return. The Service later de-
termines a deficiency relating to the tax-
able IRA distribution. W requests relief
from joint and several liability under sec-
tion 6015. W establishes that W did not
contribute to the IRA, sign paperwork re-
lating to the IRA, or otherwise act as if W
were the owner of the IRA. W, thereby, re-
buts the presumption that the IRA is attrib-
utable to W.
(c)Misappropriation of funds.Ifthe
requesting spouse did not know, and had
no reason to know, that funds intended for
the payment of tax were misappropriated
by the nonrequesting spouse for the nonre-
questing spouse’s benefit, the Service will
consider granting equitable relief although
the underpayment may be attributable in
part or in full to an item of the requesting
spouse. The Service will consider granting
relief in this case only to the extent that the
funds intended for the payment of tax were
taken by the nonrequesting spouse.
2013–43 I.R.B.399October 21, 2013

(d)Abuse. If the requesting spouse es-
tablishes that he or she was the victim of
abuse prior to the time the return was filed,
and that, as a result of the prior abuse,
the requesting spouse was not able to chal-
lenge the treatment of any items on the re-
turn, or was not able to question the pay-
ment of any balance due reported on the re-
turn, for fear of the nonrequesting spouse’s
retaliation, the Service will consider grant-
ing equitable relief even though the defi-
ciency or underpayment may be attribut-
able in part or in full to an item of the re-
questing spouse.
(e)Fraud committed by nonrequesting
spouse. The Service will consider granting
relief notwithstanding that the item giving
rise to the understatement or deficiency is
attributable to the requesting spouse, if the
requesting spouse establishes that the non-
requesting spouse’s fraud is the reason for
the erroneous item. For example, W fraud-
ulently accesses H’s brokerage account to
sell stock that H had separately received
from an inheritance. W deposits the funds
from the sale in a separate bank account
to which H does not have access. H and
W file a joint Federal income tax return
for the year, which does not report the in-
come from the sale of the stock. The Ser-
vice determines a deficiency based on the
omission of the income from the sale of
the stock. H requests relief from the defi-
ciency under section6015(f). The income
from the sale of the stock normally would
be attributable to H. Because W commit-
ted fraud with respect to H, however, and
because this fraud was the reason for the
erroneous item, the liability is properly at-
tributable to W.
.02.Circumstances under which the
Service will make streamlined determina-
tions granting equitable relief under sec-
tions 66(c) and 6015(f).
If a requesting spouse who filed a joint
return, or a requesting spouse who did not
file a joint return in a community prop-
erty state, satisfies the threshold condi-
tions of section 4.01, the Service will con-
sider whether the requesting spouse is en-
titled to a streamlined determination of eq-
uitable relief under section 66(c) or section
6015(f) under this section 4.02. If a re-
questing spouse is not entitled to a stream-
lined determination because the requesting
spouse does not satisfy all the elements in
this section 4.02, the requesting spouse is
still entitled to be considered for relief un-
der the equitable factors in section 4.03.
The Service will make streamlined deter-
minations granting equitable relief under
section 66(c) or section 6015(f), in cases
in which the requesting spouse establishes
that the requesting spouse:
(1)Marital status. Is no longer married
to the nonrequesting spouse as set forth in
section 4.03(2)(a);
(2)Economic hardship.Wouldsuf-
fer economic hardship if relief were not
granted as set forth in section 4.03(2)(b);
and
(3)Knowledge or reason to know.
(a)Section 6015(f) cases.Didnot
know or have reason to know that there
was an understatement or deficiency on
the joint income tax return, as set forth in
section 4.03(2)(c)(i), or did not know or
have reason to know that the nonrequest-
ing spouse would not or could not pay the
underpayment of tax reported on the joint
income tax return, as set forth in section
4.03(2)(c)(ii). If the nonrequesting spouse
abused the requesting spouse or main-
tained control over the household finances
by restricting the requesting spouse’s ac-
cess to financial information, and because
of the abuse or financial control, the re-
questing spouse was not able to challenge
the treatment of any items on the joint
return, or to question the payment of the
taxes reported as due on the joint return
or challenge the nonrequesting spouse’s
assurance regarding payment of the taxes,
for fear of the nonrequesting spouse’s
retaliation, then the abuse or financial con-
trol will result in this factor being satisfied
even if the requesting spouse knew or had
reason to know of the items giving rise to
the understatement or deficiency or knew
or had reason to know that the nonrequest-
ing spouse would not pay the tax liability.
(b)Section 66(c) cases. Did not know
or have reason to know of an item of
community income properly includible in
gross income, which, under the rules con-
tained in section 879(a), would be treated
as the income of the nonrequesting spouse.
.03.Factors for determining whether to
grant equitable relief.
(1)Applicability. This section 4.03
applies to a requesting spouse who re-
quests relief under section 66(c) or section
6015(f), and who satisfies the threshold
conditions of section 4.01, but does not
qualify for streamlined determinations
granting relief under section 4.02.
(2)Factors. In determining whether it
is inequitable to hold the requesting spouse
liable for all or part of the unpaid income
tax liability or deficiency, and whether full
or partial equitable relief under section
66(c) or section 6015(f) should be granted,
all the facts and circumstances of the case
are to be taken into account. The factors
listed below are designed as guides and
not intended to comprise an exclusive list.
Other factors relevant to a specific claim
for relief may also be taken into account in
making the determination. In evaluating a
claim for relief, no one factor or a majority
of factors necessarily determines the out-
come. The degree of importance of each
factor varies depending on the requesting
spouse’s facts and circumstances. Abuse
or the exercise of financial control by
the nonrequesting spouse is a factor that
may impact the other factors, as described
below. Factors to consider include the
following:
(a)Marital status. Whether the request-
ing spouse is no longer married to the non-
requesting spouse as of the date the Service
makes its determination. If the requesting
spouse is still married to the nonrequesting
spouse, this factor is neutral. If the request-
ing spouse is no longer married to the non-
requesting spouse, this factor will weigh in
favor of relief. For purposes of this sec-
tion, a requesting spouse will be treated as
being no longer married to the nonrequest-
ing spouse only in the following situations:
(i) The requesting spouse is divorced
from the nonrequesting spouse,
(ii) The requesting spouse is legally
separated from the nonrequesting spouse
under applicable state law,
(iii) The requesting spouse is a widow
or widower and is not an heir to the non-
requesting spouse’s estate that would have
sufficient assets to pay the tax liability, or
(iv) The requesting spouse has not been
a member of the same household as the
nonrequesting spouse at any time during
the 12-month period ending on the date
the Service makes its determination. For
these purposes, a temporary absence (e.g.,
due to incarceration, illness, business, mil-
itary service, or education) is not consid-
ered separation if the absent spouse is ex-
pected to return to the household. See
Treas. Reg. § 1.6015–3(b)(3)(i). A re-
questing spouse is a member of the same
household as the nonrequesting spouse for
October 21, 20134002013–43 I.R.B.

any period in which the spouses maintain
the same residence.
(b)Economic hardship.Whetherthe
requesting spouse will suffer economic
hardship if relief is not granted. For pur-
poses of this factor, an economic hardship
exists if satisfaction of the tax liabil-
ity in whole or in part will cause the
requesting spouse to be unable to pay rea-
sonable basic living expenses. Whether
the requesting spouse will suffer eco-
nomic hardship is determined based on
rules similar to those provided in Treas.
Reg. § 301.6343–1(b)(4), and the Service
will take into consideration a requesting
spouse’s current income and expenses and
the requesting spouse’s assets. In deter-
mining the requesting spouse’s reasonable
basic living expenses, the Service will
consider whether the requesting spouse
shares expenses or has expenses paid
by another individual (such as a family
member, including a current spouse). If
denying relief from the joint and several
liability will cause the requesting spouse
to suffer economic hardship, this factor
will weigh in favor of relief. If denying
relief from the joint and several liability
will not cause the requesting spouse to
suffer economic hardship, this factor will
be neutral.
In determining whether the requesting
spouse would suffer economic hardship if
relief is not granted, the Service will com-
pare the requesting spouse’s income to
the Federal poverty guidelines (as updated
periodically in the Federal Register by the
U.S. Department of Health and Human
Services under the authority of 42 U.S.C.
§ 9902(2)) for the requesting spouse’s
family size and will determine by how
much, if at all, the requesting spouse’s
monthly income exceeds the spouse’s rea-
sonable basic monthly living expenses.
This factor will weigh in favor of relief if
the requesting spouse’s income is below
250% of the Federal poverty guidelines,
unless the requesting spouse has assets
out of which the requesting spouse can
make payments towards the tax liability
and still adequately meet the requesting
spouse’s reasonable basic living expenses.
If the requesting spouse’s income exceeds
250% of the Federal poverty guidelines,
this factor will still weigh in favor of relief
if the requesting spouse’s monthly income
exceeds the requesting spouse’s reason-
able basic monthly living expenses by
$300 or less, unless the requesting spouse
has assets out of which the requesting
spouse can make payments towards the tax
liability and still adequately meet the re-
questing spouse’s reasonable basic living
expenses. If the requesting spouse’s in-
come exceeds 250% of the Federal poverty
guidelines and monthly income exceeds
monthly expenses by more than $300, or
if the requesting spouse qualifies under
either standard but has sufficient assets to
make payments towards the tax liability
and still adequatelymeet the requesting
spouse’s reasonable basic living expenses,
the Service will consider all facts and
circumstances (including the size of the
requesting spouse’s household) in deter-
mining whether the requesting spouse
would suffer economic hardship if relief
is not granted. If the requesting spouse is
deceased, this factor is neutral.
(c)Knowledge or reason to know.
(i)Understatement cases.
(A)Section 6015(f) cases.Whetherthe
requesting spouse knew or had reason to
know of the item giving rise to the un-
derstatement or deficiency as of the date
the joint return (including a joint amended
return) was filed, or the date the request-
ing spouse reasonably believed the joint
return was filed. If the requesting spouse
did not know and had no reason to know
of the item giving rise to the understate-
ment, this factor will weigh in favor of
relief. If the requesting spouse knew or
had reason to know of the item giving
rise to the understatement, this factor will
weigh against relief. Actual knowledge
of the item giving rise to the understate-
ment or deficiency will not be weighed
more heavily than any other factor. De-
pending on the facts and circumstances, if
the requesting spouse was abused by the
nonrequesting spouse (as described in sec-
tion 4.03(2)(c)(iv)), or the nonrequesting
spouse maintained control of the house-
hold finances by restricting the requesting
spouse’s access to financial information,
and because of the abuse or financial con-
trol, the requesting spouse was not able to
challenge the treatment of any items on the
joint return for fear of the nonrequesting
spouse’s retaliation, this factor will weigh
in favor of relief even if the requesting
spouse knew or had reason to know of the
items giving rise to the understatement or
deficiency.
(B)Section 66(c) cases.Whetherthe
requesting spouse knew or had reason
to know of an item of community in-
come properly includible in gross income,
which, under the rules contained in section
879(a), would be treated as the income of
the nonrequesting spouse.
(ii)Underpayment cases. In the case
of an income tax liability that was prop-
erly reported but not paid, whether, as of
thedatethereturnwasfiledorthedate
the requesting spouse reasonably believed
the return was filed, the requesting spouse
knew or had reason to know that the non-
requesting spouse would not or could not
pay the tax liability at that time or within a
reasonable period of time after the filing of
the return. This factor will weigh in favor
of relief if the requesting spouse reason-
ably expected the nonrequesting spouse to
pay the tax liability reported on the return.
A reasonable expectation of payment will
be presumed if the spouses submitted a re-
quest for an installment agreement to pay
the tax reported as due on the return. To
benefit from the presumption, the request
for an installment agreement must be filed
by the later of 90 days after the due date
for payment of the tax, or 90 days after the
return was filed. The request must detail
the plan for paying the tax, interest, and
penalties, satisfy the liability within a rea-
sonable time, and it must not be unreason-
able for the requesting spouse to believe
that the nonrequesting spouse will be able
to make the payments contemplated in the
requested installment agreement.
This factor will weigh against relief if,
based on the facts and circumstances of
the case, it was not reasonable for the re-
questing spouse to believe that the non-
requesting spouse would or could pay the
tax liability shown on the return. For ex-
ample, if prior to the return being filed,
or the date the requesting spouse reason-
ably believed the return was filed, the re-
questing spouse knew of the nonrequesting
spouse’s prior bankruptcies, financial dif-
ficulties, or other issues with the Service or
other creditors, or was otherwise aware of
difficulties in timely paying bills, then this
factor will generally weigh against relief.
Depending on the facts and circum-
stances, if the requesting spouse was
abused by the nonrequesting spouse (as
described in section 4.03(2)(c)(iv)), or the
nonrequesting spouse maintained control
of the household finances by restricting
2013–43 I.R.B.401October 21, 2013

the requesting spouse’s access to financial
information, and because of the abuse or
financial control, the requesting spouse
was not able to question the payment of
the taxes reported as due on the return
or challenge the nonrequesting spouse’s
assurance regarding payment of the taxes
for fear of the nonrequesting spouse’s re-
taliation, this factor will weigh in favor of
relief even if the requesting spouse knew
or had reason to know about the nonre-
questing spouse’s intent or ability to pay
the taxes due.
With respect to an underpayment of tax
on an amended return that reports a liabil-
ity based on items not properly reported
on the original return, the initial inquiry
is whether, as of the date the amended re-
turn was filed, or the date the requesting
spouse reasonably believed the amended
return was filed, the requesting spouse rea-
sonably expected that the nonrequesting
spouse would pay the tax within a rea-
sonable period of time. If so, this fac-
tor will weigh in favor of relief. How-
ever, if it was not reasonable for the re-
questing spouse to expect that the nonre-
questing spouse would pay the tax, the re-
questing spouse’s knowledge or reason to
know of the understatement on the origi-
nal return will also be considered. If the
requesting spouse knew or had reason to
know of the item giving rise to the under-
statement on the original return, then this
factor will weigh against relief. If the re-
questing spouse did not know or have rea-
son to know of the item, then this factor
will weigh in favor of relief.
(iii)Reason to know. The facts and cir-
cumstances that are considered in deter-
mining whether the requesting spouse had
reason to know of an understatement, or
reason to know whether the nonrequesting
spouse could or would pay the reported tax
liability, include, but are not limited to, the
requesting spouse’s level of education, any
deceit or evasiveness of the nonrequest-
ing spouse, the requesting spouse’s de-
gree of involvement in the activity gener-
ating the income tax liability, the request-
ing spouse’s involvement in business or
household financialmatters, the request-
ing spouse’s business or financial exper-
tise, and any lavish or unusual expendi-
tures compared with past spending levels.
(iv)Abuse by the nonrequesting spouse.
For purposes of this revenue procedure, if
the requesting spouse establishes that he or
she was the victim of abuse (not amounting
to duress, see Treas. Reg. § 1.6015–1(b)),
then depending on the facts and circum-
stances of the requesting spouse’s situa-
tion, the abuse may result in certain fac-
tors weighing in favor of relief when other-
wise the factor may have weighed against
relief. Abuse comes in many forms and
can include physical, psychological, sex-
ual, or emotional abuse, including efforts
to control, isolate, humiliate, and intim-
idate the requesting spouse, or to under-
mine the requesting spouse’s ability to rea-
son independently and be able to do what
is required under the tax laws. All the
facts and circumstances are considered in
determining whether a requesting spouse
was abused. The impact of a nonrequest-
ing spouse’s alcohol or drug abuse is also
considered in determining whether a re-
questing spouse was abused. Depending
on the facts and circumstances, abuse of
the requesting spouse’s child or other fam-
ily member living in the household may
constitute abuse of the requesting spouse.
(d)Legal obligation.Whetherthe
requesting spouse or the nonrequesting
spouse has a legal obligation to pay the
outstanding Federal income tax liability.
For purposes of this factor, a legal obliga-
tion is an obligation arising from a divorce
decree or other legally binding agreement.
This factor will weigh in favor of relief if
the nonrequesting spouse has the sole legal
obligation to pay the outstanding income
tax liability pursuant to a divorce decree
or agreement. This factor, however, will
be neutral if the requesting spouse knew
or had reason to know, when entering into
the divorce decree or agreement, that the
nonrequesting spouse would not pay the
income tax liability. This factor will weigh
against relief if the requesting spouse has
the sole legal obligation. The fact that the
nonrequesting spouse has been relieved of
liability for the taxes at issue as a result of
a discharge in bankruptcy is disregarded in
determining whether the requesting spouse
has the sole legal obligation. This factor
will be neutral if, based on an agreement
or consent order, both spouses have a legal
obligation to pay the outstanding income
tax liability, the spouses are not sepa-
rated or divorced, or the divorce decree or
agreement is silent as to any obligation to
pay the outstanding income tax liability.
(e)Significant benefit.Whetherthe
requesting spouse significantly benefit-
ted from the unpaid income tax liabil-
ity or understatement. See Treas. Reg.
§ 1.6015–2(d). A significant benefit is
any benefit in excess of normal support.
For example, if the requesting spouse en-
joyed the benefits of a lavish lifestyle,
such as owning luxury assets and taking
expensive vacations, this factor will weigh
against relief. If, however, the nonrequest-
ing spouse controlled the household and
business finances or there was abuse (as
described in section 4.03(2)(c)(iv)) such
that the nonrequesting spouse made the
decision on spending funds for a lavish
lifestyle, then this mitigates this factor so
that it is neutral. If only the nonrequesting
spouse significantly benefitted from the
unpaid tax or understatement, and the re-
questing spouse had little or no benefit, or
the nonrequesting spouse enjoyed the ben-
efit to the requesting spouse’s detriment,
this factor will weigh in favor of relief. If
the amount of unpaid tax or understate-
ment was small such that neither spouse
received a significant benefit, then this
factor is neutral. Whether the amount of
unpaid tax or understatement is small such
that neither spouse received a significant
benefit will vary depending on the facts
and circumstances of each case.
(f)Compliance with income tax laws.
Whether the requesting spouse has made
a good faith effort to comply with the in-
come tax laws in the taxable years follow-
ing the taxable year or years to which the
request for relief relates.
(i) If the requesting spouse is compliant
for taxable years after being divorced from
the nonrequesting spouse, then this factor
will weigh in favor of relief. If the re-
questing spouse is not compliant, then this
factor will weigh against relief. If the re-
questing spouse made a good faith effort to
comply with the tax laws but was unable to
fully comply, then this factor will be neu-
tral. For example, if the requesting spouse
timely filed an income tax return but was
unable to fully pay the tax liability due to
the requesting spouse’s poor financial or
economic situation after the divorce, then
this factor will be neutral.
(ii) If the requesting spouse remains
married to the nonrequesting spouse,
whether or not legally separated or living
apart, and continues to file joint returns
with the nonrequesting spouse after re-
questing relief, then this factor will be
neutral if the joint returns are compliant
October 21, 20134022013–43 I.R.B.

with the tax laws, but will weigh against
relief if the returns are not compliant.
(iii) If the requesting spouse remains
married to the nonrequesting spouse but
files separate returns, this factor will weigh
infavorofreliefiftherequestingspouseis
compliant with the taxlaws and will weigh
against relief if the requesting spouse is not
compliant with the tax laws. If the request-
ing spouse made a good faith effort to com-
ply with the tax laws but was unable to
fully comply, then this factor will be neu-
tral. For example, if the requesting spouse
timely filed an income tax return but was
unable to fully pay the tax liability due to
the requesting spouse’s poor financial or
economic situation as a result of being sep-
arated or living apart from the nonrequest-
ing spouse, then this factor will be neutral.
(g)Mental or physical health.Whether
the requesting spouse was in poor physical
or mental health. This factor will weigh
infavorofreliefiftherequestingspouse
was in poor mental or physical health at the
time the return or returns for which the re-
quest for relief relates were filed (or at the
time the requesting spouse reasonably be-
lieved the return or returns were filed), or
at the time the requesting spouse requested
relief. The Service will consider the na-
ture, extent, and duration of the condition,
including the ongoing economic impact of
the illness. If the requesting spouse was
in neither poor physical nor poor mental
health, this factor is neutral.
.04.Refunds. In both understatement
and underpayment cases, a requesting
spouse is eligible for a refund of sepa-
rate payments made by the requesting
spouse after July 22, 1998, if the request-
ing spouse establishes that the funds used
to make the payment for which a refund
is sought were provided by the requesting
spouse. A requesting spouse is not eligible
for refunds of payments made with the
joint return, joint payments, or payments
that the nonrequesting spouse made. A re-
questing spouse, however, may be eligible
for a refund of the requesting spouse’s por-
tion of the requesting and nonrequesting
spouse’s joint overpayment from another
tax year that was applied to the joint in-
come tax liability to the extent that the
requesting spouse can establish that the
requesting spouse provided the funds for
the overpayment. The availability of re-
funds is subject to the refund limitations
of section 6511.

SUPPLEME
NTARY INFORMATION:
Background
On Decembe
r 27, 2011, the IRS and
the Treas
ury Department published in the
Federal R
egister(76 FR 81060) tem-
porary re
gulations (TD 9564) regarding
the accou
nting for, and dispositions of,
propert
y subject to depreciation under
section
168 (MACRS property). The
tempora
ry regulations also amended the
general
asset account regulations under
§1.168(
i)–1. On the same date, the IRS
publis
hed in theFederal Register(76 FR
81128)
a notice of proposed rulemaking
(REG–1
68745–03) cross-referencing the
tempor
ary regulations (2011 proposed
regula
tions). The IRS and the Treasury
Depar
tment received numerous written
comme
nts responding to the notice of
propo
sed rulemaking and held a public
heari
ng on May 9, 2012.
The te
mporary regulations generally
apply
to taxable years beginning on or after
Janua
ry 1, 2012. In response to the com-
ment
s received and the statements made at
the p
ublic hearing, the IRS and the Trea-
sury
Department releasedNotice 2012–73,
2012
–51 I.R.B. 713, on November 20,
2012
, announcing that, to help taxpayers
tran
sition to the final regulations, the IRS
and
the Treasury Department will change
the
applicability date of the temporary
reg
ulations to taxable years beginning on
or after Janua
ry 1, 2014, while permitting
taxpayers to c
hoose to apply the temporary
regulations t
o taxable years beginning on
or after Janua
ry 1, 2012, and before the
applicabilit
y date of the final regulations.
Notice 2012–
73 also alerts taxpayers that
the IRS and th
e Treasury Department in-
tend to publi
sh final regulations in 2013
and expect th
e final regulations to apply
to taxable y
ears beginning on or after Jan-
uary 1, 2014
, but that the final regulations
would permi
t taxpayers to apply the pro-
visions of t
he final regulations to taxable
years begi
nning on or after January 1,
2012. On De
cember 17, 2012, the IRS
and the Tre
asury Department published
in theFede
ral Register(77 FR 74583) a
technical
amendment to TD 9564, which
amended t
he applicability date of the
temporar
y regulations to taxable years be-
ginning o
n or after January 1, 2014, while
permitti
ng taxpayers to choose to apply
the temp
orary regulations to taxable years
beginni
ng on or after January 1, 2012, and
before t
he applicability date of the final
regulat
ions.
Notice 2
012–73 also alerts taxpayers
that the
IRS and the Treasury Department
intend t
o revise the disposition rules in the
tempor
ary regulations. After considering
the com
ment letters and the statements
made at
the public hearing, the IRS and
the Tre
asury Department decided to with-
draw th
e 2011 proposed regulations under
§§1.1
68(i)–1 and 1.168(i)–8 and to pro-
pose n
ew regulations. This document
conta
ins the new proposed regulations
under
§§1.168(i)–1 and 1.168(i)–8 as
well a
s new proposed regulations under
§1.1
68(i)–7. The temporary regulations
unde
r §§1.168(i)–1T and 1.168(i)–8T are
not r
evised and taxpayers continue to have
the o
ption of applying those temporary
regu
lations to taxable years beginning on
or af
ter January 1, 2012, and before the
app
licability date of the final regulations.
Sum
mary of Comments and
Exp
lanation of Provisions
I.O
verview
The
se proposed regulations under
§§1
.168(i)–1 and 1.168(i)–8 include many
of t
he provisions contained in the 2011
pro
posed regulations and the temporary
October 21, 20134042013–43 I.R.B.

regulations under §§1.168(i)–1T and
1.168(i)–8T. However, these proposed
regulations provide significant changes
to the rules relating to the determination
of the asset disposed of and a qualify-
ing disposition of an asset in a general
asset account, and the proposed regu-
lations under §§1.168(i)–1, 1.168(i)–7,
and 1.168(i)–8 provide new rules for par-
tial dispositions of assets. The IRS and
the Treasury Department intend to pub-
lish final regulations under §§1.168(i)–1,
1.168(i)–7, and 1.168(i)–8 later this year.
Accordingly, these proposed regulations
generally are proposed to apply to taxable
years beginning on or after January 1,
2014.
II.Disposition Rules for MACRS Property
The IRS and the Treasury Department
received several comments on the dis-
position rules under §§1.168(i)–1T and
1.168(i)–8T. Most of the comments related
to dispositions of structural components
of a building, dispositions of assets in a
general asset account, and determination
of the unadjusted depreciable basis of a
disposed asset in a multiple asset account
or a general asset account.
A.Determination of Asset Disposed Of
and Partial Dispositions
1. The temporary regulations
The temporary regulations under
§1.168(i)–8T provide rules for determin-
ing gain or loss upon the disposition of
MACRS property that are generally con-
sistent with the disposition rules under
§1.168–6 of the proposed regulations on
the Accelerated Cost Recovery System of
former section 168 (ACRS) (which have
been generally applied to MACRS prop-
erty). However, if anabandoned asset is
subject to nonrecourseindebtedness, the
temporary regulations clarify that the asset
is treated in the same manner as an asset
disposed of by sale.
Section 1.168–2(l)(1) of the proposed
ACRS regulations provides that a dispo-
sition does not include the retirement of
a structural component of a building and,
consequently, §1.168–6(b) of the proposed
ACRS regulations provides that no loss is
recognized upon the retirement of a struc-
tural component of a building. The tem-
porary regulations expand the definition
of disposition for MACRS property to in-
clude the retirement of a structural com-
ponent of a building and, accordingly, the
temporary regulations allow the recogni-
tion of a loss upon such a retirement.
The temporary regulations under
§1.168(i)–1T provide rules for establish-
ing general asset accounts, for computing
depreciation for general asset accounts,
and for determining gain or loss upon
the disposition of assets in general as-
set accounts. Section 1.168(i)–1T(e)(2)
provides that, in general, no loss is rec-
ognized upon the disposition of an asset
from a general asset account. However,
§1.168–1T(e)(3)(iii) provides that a tax-
payer may elect to recognize gain or loss
upon the disposition of an asset in a gen-
eral asset account if there is a qualifying
disposition. The temporary regulations
define the term “disposition” to include
the retirement of a structural component
of a building and define the term “quali-
fying disposition” to allow the recognition
of gain or loss upon most dispositions of
assets in general asset accounts. Thus, a
taxpayer has the option of recognizing a
loss on most dispositions of assets in gen-
eral asset accounts under the temporary
regulations.
The temporary regulations under
§§1.168(i)–1T and 1.168(i)–8T also pro-
vide rules for determining the disposed
asset. Those sections of the temporary
regulations provide that the facts and
circumstances of each disposition are
considered in determining the appro-
priate disposed asset. In general, the
asset for disposition purposes cannot be
larger than the unit of property as deter-
mined under §1.263(a)–3(e)(2), (e)(3),
and (e)(5) or as otherwise provided in
published guidance in theFederal Reg-
isteror in the Internal Revenue Bul-
letin. However, under §§1.168(i)–1T and
1.168(i)–8T, each building is the asset for
disposition purposes, unless more than
one building is treated as the asset un-
der §1.1250–1(a)(2)(ii). If the building
includes two or more condominium or
cooperative units, then each condominium
or cooperative unit (instead of the build-
ing) is the asset for disposition purposes.
Consistent with including a retirement of
a structural component of a building as
a disposition, the temporary regulations
provide that each structural component
of a building, condominium unit, or co-
operative unit is the asset for disposition
purposes. Further, if a taxpayer prop-
erly includes an item in one of the asset
classes 00.11 through 00.4 of Rev. Proc.
87–56 (1987–2 C.B. 674), (see 26 CFR
601.601(d)(2)(ii)(b)) or classifies an item
in one of the categories under section
168(e)(3) (other than a category that in-
cludes buildings or structural components;
for example, retail motor fuels outlet and
qualified leasehold improvement prop-
erty), each item is the asset provided it
is not larger than the unit of property as
determined under §1.263(a)–3(e)(3) or
(e)(5). Consistent with section 168(i)(6),
the temporary regulations also provide
that if the taxpayer places in service an
improvement or addition to an asset after
the taxpayer placed the asset in service,
the improvement or addition is a sepa-
rate asset for depreciation purposes. The
temporary regulations also provide that a
taxpayer generally may use any reason-
able, consistent method to treat each of an
asset’s components as the asset for dispo-
sition purposes.
2. Comments on the temporary regulations
Several commenters stated that requir-
ing taxpayers to treat the structural compo-
nents of a building as assets separate from
the underlying building increases admin-
istrative burdens for taxpayers because of
the necessity to track the components. Fur-
ther, while the temporary regulations per-
mit taxpayers to define the asset for dis-
position purposes at the smallest compo-
nent level, effectively allowing taxpayers
the ability to recognize a loss on the par-
tial retirement of a larger item, some com-
menters indicated that such an approach
is unduly complicated and will pose sig-
nificant administrative burdens for taxpay-
ers. Other commenters suggested that the
ability to use any reasonable, consistent
method to treat each of an asset’s compo-
nents as the asset for disposition purposes
be expanded to assets classified in asset
classes 00.11 through 00.4 of Rev. Proc.
87–56, which accounts for the property
that a taxpayer typically uses in its busi-
ness (for example, office furniture, com-
puters, cars, corporate jets, and land im-
provements (other than a building and its
structural components)).
Several commenters suggested that the
use of general asset accounts be the default
2013–43 I.R.B.405October 21, 2013

rule to eliminate traps for taxpayers. Com-
menters stated that requiring taxpayers
to make a general asset account election
when structural components are placed in
service to forgo the loss on dispositions
of structural components occurring years
later was a trap for taxpayers. For exam-
ple, because a taxpayer that did not elect
general asset account treatment cannot
forgo a mandatory loss on a disposition
of a structural component, the taxpayer
would be required to capitalize the re-
placement of the structural component
under §1.263(a)–3(k)(1)(i) even if the
replacement of the structural component
does not constitute the replacement of a
major component, a significant portion
of a major component, or a substantial
structural part of the building unit of prop-
erty under §§1.263(a)–3(k)(1)(vi) and
1.263(a)–3(k)(6)(ii). Further, because
some structural components are defined
in §1.48–1(e)(2) at a diminutive level (for
example, one window in a building), com-
menters stated that absent including all
structural components in a general asset
account, taxpayers run the risk of failing
to identify every disposition in a given
taxable year.
The IRS and the Treasury Department
do not think that the use of general asset
accounts should be the default rule. How-
ever, the IRS and the Treasury Department
agree that taxpayers that do not elect gen-
eral asset account treatment should have
the same flexibility to forgo a loss upon the
disposition of a structural component as
taxpayers that elect general asset account
treatment. As discussed in this preamble,
these proposed regulations make signifi-
cant modifications to the disposition rules
to allow this flexibility.
3. Structural components
These proposed regulations change the
rule in the temporary regulations under
§§1.168(i)–1T and 1.168(i)–8T that each
structural component of a building, condo-
minium, or cooperative is the asset for tax
disposition purposes. The proposed regu-
lations provide that a building (including
its structural components), a condominium
(including its structural components), or a
cooperative (including its structural com-
ponents) is the asset for disposition pur-
poses. This rule allows taxpayers to forgo
a loss upon the disposition of a structural
component of a building without making a
general asset account election.
4. Partial dispositions
A. Assets not included in general asset
accounts
The proposed regulations under
§1.168(i)–8 also provide that the disposi-
tion rules apply to a partial disposition of
an asset (for example, the disposition of a
roof (or a portion of the roof)). This rule
allows taxpayers to claim a loss upon the
disposition of a structural component (or a
portion thereof) of a building or upon the
disposition of a component (or a portion
thereof) of any other asset without iden-
tifying the component as an asset before
the disposition event. The partial dispo-
sition rule also minimizes circumstances
in which an original part and any subse-
quent replacements of the same part are
required to be capitalized and depreciated
simultaneously. These proposed regula-
tions provide examples demonstrating the
application of the partial disposition rule.
In many cases, the partial disposition
rule is elective (“partial disposition elec-
tion”). However, consistent with the oper-
ation of sections 165, 168(i)(7), 1031, and
1033, and because sales of a portion of an
asset are common, the partial disposition
rule is required to be applied to a disposi-
tion of a portion of an asset as a result of
a casualty event described in section 165,
to a disposition of a portion of an asset for
which gain (determined without regard to
section 1245 or 1250) is not recognized
inwholeorinpartundersection1031or
1033, to a transfer of a portion of an as-
set in a step-in-the-shoes transaction de-
scribed in section 168(i)(7)(B), or to a sale
of a portion of an asset. Consequently, a
disposition includes a disposition of a por-
tion of an asset under these circumstances,
even if the taxpayer does not make the par-
tial disposition election for that disposed
portion. For other transactions, a disposi-
tion includes a disposition of a portion of
an asset only if the taxpayer makes the par-
tial disposition election for that disposed
portion.
A taxpayer may make the partial dispo-
sition election for the disposition of a por-
tion of any type of MACRS property, in-
cluding an asset that is properly included
in one of the asset classes 00.11 through
00.4 of Rev. Proc. 87–56. However, con-
sistent with section 168(i)(6), a taxpayer
making the partial disposition election for
the disposition of a portion of an asset that
is properly included in one of the asset
classes 00.11 through 00.4 of Rev. Proc.
87–56 must classify the replacement por-
tion of the asset under the same asset class
as the disposed portion of the asset.
The partial disposition election is made
on the taxpayer’s timely filed original Fed-
eral tax return, including extensions, for
the taxable year in which the portion of the
asset is disposed of by the taxpayer. This
election may not be made or revoked by
the filing of an application for a change in
method of accounting. A taxpayer may re-
voke a partial disposition election by fil-
ing a request for a letter ruling and ob-
taining the consent of the Commissioner
of Internal Revenue to revoke this elec-
tion. The Commissioner may grant a re-
quest to revoke this election if the taxpayer
acted reasonably and in good faith, and the
revocation will not prejudice the interests
of the Government. In deciding whether
to grant such a request, the Commissioner
anticipates applying standards similar to
the standards under 26 CFR 301.9100–3
for granting extensions of time for mak-
ing regulatory elections. If a taxpayer
chooses to apply these proposed regula-
tions to its taxable year beginning in 2012
or 2013, these proposed regulations also
provide rules for making the partial dispo-
sition election for the portion of an asset
disposed of by the taxpayer during those
taxable years.
These proposed regulations also pro-
vide a special partial disposition rule to ad-
dress commenters’ concerns about the ef-
fect of an IRS disallowance of a taxpayer’s
characterization of the replacement of a
portion of an asset as a repair. When the
IRS disallows a taxpayer’s repair deduc-
tion for the amount paid or incurred for the
replacement of a portion of an asset and
capitalizes such amount under §1.263(a)–2
or §1.263(a)–3, the taxpayer may make the
partial disposition election for the disposi-
tion of the portion of the asset to which the
IRS’s adjustment pertains by filing an ap-
plication for change in accounting method,
provided the asset of which the disposed
portion was a part is owned by the taxpayer
at the beginning of the year of change (as
defined for purposes of section 446(e)).

B. Assets included in general asset
accounts
Similarly, the proposed regulations un-
der §1.168(i)–1 also provide that the dis-
position rules apply to a partial disposi-
tion of an asset included in a general as-
set account. Consequently, a disposition
includes a disposition of a portion of an as-
set as a result of a casualty event described
in section 165, a disposition of a portion of
an asset for which gain (determined with-
out regard to section 1245 or 1250) is not
recognized in whole or in part under sec-
tion 1031 or 1033, a transfer of a portion of
an asset in a transaction described in sec-
tion 168(i)(7)(B), a sale of a portion of an
asset, or a disposition of a portion of an
asset in a transaction described under the
anti-abuse rules applicable to general as-
set accounts. For other transactions, a dis-
position includes a disposition of a portion
of an asset only if the taxpayer makes the
election to terminate the general asset ac-
count upon the disposition of all assets, in-
cluding that disposed portion, in that gen-
eral asset account or makes the qualifying
disposition election for that disposed por-
tion. A separate partial disposition elec-
tion is not provided for assets in a general
asset account because a taxpayer can claim
a loss upon the disposition of an asset (or a
portion thereof) in a general asset account
only when the taxpayer makes these two
elections.
5. Components of an asset
Because the partial disposition rule
under these proposed regulations allows
taxpayers to treat the disposition of an as-
set’s component as a disposition, the IRS
and the Treasury Department believe that
the rule in §§1.168(i)–1T and 1.168(i)–8T
allowing taxpayers to use any reason-
able, consistent method to treat an asset’s
components as the asset for disposition
purposes is no longer needed. Accord-
ingly, these proposed regulations do not
include that temporary regulations rule.
The IRS and the Treasury Department
request comments addressing whether the
rule in §§1.168(i)–1T and 1.168(i)–8T
allowing taxpayers to use any reason-
able, consistent method to treat an asset’s
components as the asset for disposition
purposes is still needed.
6. Disposition definition
Consistent with these changes, these
proposed regulations modify the tempo-
rary regulations’ definition of a disposition
under §§1.168(i)–1T and 1.168(i)–8T to
provide that a disposition includes the
disposition of a structural component
(or a portion thereof) of a building only
if the partial disposition rule applies to
such structural component (or a portion
thereof).
7. General asset accounts
Finally, these proposed regulations
change the temporary regulation defi-
nition of a qualifying disposition under
§1.168(i)–1T(e)(3)(iii). The purpose of a
general asset account is to reduce the ad-
ministrative burden of tracking deprecia-
ble assets. This purpose was accomplished
in the final regulations for general asset
accounts under §1.168(i)–1 (as in effect
before the temporary regulations under
§1.168(i)–1T) by allowing a taxpayer to
group assets in one or more general asset
accounts and by allowing a taxpayer to
elect to terminate general asset account
treatment only when the taxpayer disposes
of all of the assets, or the last asset, in the
account, or disposes of an asset in a qual-
ifying disposition, which generally was a
casualty or other extraordinary event. The
temporary regulations under §1.168(i)–1T
expand a qualifying disposition to include
generally any disposition and, as a result,
increased the administrative burden of
tracking depreciable assets. To reduce this
burden, the IRS and the Treasury Depart-
ment have decided to change the definition
of a qualifying disposition so that it is
the same as it was under the final regu-
lations for general asset accounts under
§1.168(i)–1 (as in effect before the tem-
porary regulations under §1.168(i)–1T).
Accordingly, these proposed regulations
provide that a qualifying disposition is a
disposition that does not involve all the
assets, the last asset, or the remaining
portion of the last asset, remaining in a
general asset account and that is: (1) a
direct result of a fire,storm, shipwreck, or
other casualty, or from theft; (2) a chari-
table contribution for which a deduction
is allowable under section 170; (3) a di-
rect result of a cessation, termination, or
disposition of a business, manufacturing,
or other income producing process, oper-
ation, facility, plant, or other unit (other
than by transfer to a supplies, scrap, or
similar account); or (4) generally a trans-
action to which a nonrecognition section
of the Code applies.
B.Determination of Basis and
Identification of Disposed or Converted
Asset
The temporary regulations under
§§1.168(i)–1T and 1.168(i)–8T provide
that if the disposed asset is in a general as-
set account, is in a multiple asset account,
or is a component of a larger asset, and it is
impracticable from the taxpayer’s records
to determine the unadjusted depreciable
basis of the disposed asset, the taxpayer
may use any reasonable method that is
consistently applied to the taxpayer’s
general asset accounts, multiple asset ac-
counts, or larger assets, as applicable.
Several commenters requested that one
or more specific methodologies be pro-
vided. They suggested using replacement
cost adjusted for inflation using an objec-
tive index, using third-party construction
estimating and valuation services, or using
relative fair market value of acquired com-
ponents.
In response, these proposed regulations
provide nonexclusive examples of reason-
able methods. Such examples include: (1)
discounting the cost ofthe replacement as-
set to its placed-in-service year cost using
the Consumer Price Index; (2) apro rata
allocation of the unadjusted depreciable
basis of the general asset account or mul-
tiple asset account, as applicable, based on
the replacement cost of the disposed asset
and the replacement cost of all of the as-
sets in the general asset account or multi-
ple asset account, as applicable; and (3) a
study allocating the cost of the asset to its
individual components. The IRS and the
Treasury Department expect that reason-
able methods are available that use infor-
mation readily available or known to the
taxpayer and do not necessitate undertak-
ing expensive studies.
As previously mentioned, these pro-
posed regulations do not include the tem-
porary regulation rule in §§1.168(i)–1T
and 1.168(i)–8T that allows taxpayers to
use any reasonable, consistent method to
treat an asset’s components as the asset for
tax disposition purposes. Consistent with
2013–43 I.R.B.407October 21, 2013

this change, these proposed regulations do
not include the temporary regulation rules
in §§1.168(i)–1T and 1.168(i)–8T regard-
ing the determination of the unadjusted
depreciable basis, and identification, of
the disposed component of a larger as-
set. However, these proposed regulations
provide rules regarding the determination
of the unadjusted depreciable basis, and
identification, of the disposed portion of
an asset when the partial disposition rule
applies.
If the partial disposition rule applies,
these proposed regulations provide that a
taxpayer may use any reasonable method
for determining the unadjusted deprecia-
ble basis of the disposed portion of the
asset. Also, if a taxpayer disposes of more
than one portion of the same asset, the tax-
payer may use any reasonable method that
is consistently applied to all portions of
the same asset for purposes of determining
the unadjusted depreciable basis of each
disposed portion of the asset. These pro-
posed regulations provide nonexclusive
examples of reasonable methods.
If a taxpayer disposes of a portion of
the asset and the partial disposition rule
applies to that disposition, these proposed
regulations provide rules regarding the
identification of the asset. When it is im-
practicable from the taxpayer’s records to
determine the particular taxable year in
which the asset was placed in service by
the taxpayer, the taxpayer must identify
the asset by using the methods allowed
when the asset is in a general asset account
or a multiple asset account: the first-in,
first-out (FIFO) method, the modified
FIFO method, a mortality dispersion table
if the asset is a mass asset, or any other
method designated by the Secretary in
published guidance. A last-in, first-out
(LIFO) method is not permitted.
C.Other Changes
The proposed regulations under
§1.168(i)–8 provide that if a taxpayer
disposes of a portion of an asset and the
partial disposition rule applies to that dis-
position, the taxpayer must account for the
disposed portion in a single asset account
beginning in the taxable year in which
the disposition occurs. This new rule also
is provided in the proposed regulations
under §1.168(i)–7.
The proposed regulations under
§§1.168(i)–1 and 1.168(i)–8 also provide
examples demonstrating the interaction
between the disposition rules and the cap-
italization of tangible property rules under
§1.263(a)–3.
Proposed Effective Date
These regulations are proposed to ap-
ply to taxable years beginning on or after
January 1, 2014. The regulations also per-
mit taxpayers to rely on the provisions of
the proposed regulations for taxable years
beginning on or after January 1, 2012,
and before the applicability date of the
final regulations. The proposed regula-
tions provide that taxpayers may apply the
provisions of the final regulations to tax-
able years beginning on or after January
1, 2012. The temporary regulations under
§§1.168(i)–1T and 1.168(i)–8T allow tax-
payers to apply the temporary regulations
to taxable years beginning on or after Jan-
uary 1, 2012, but the final regulations will
provide that taxpayers may not apply the
temporary regulations to taxable years be-
ginning on or after January 1, 2014.
Special Analyses
It has been determined that this notice
of proposed rulemaking is not a significant
regulatory action as defined in Executive
Order 12866, as supplemented by Execu-
tive Order 13563. Therefore, a regulatory
assessment is not required. It also has been
determined that section 553(b) of the Ad-
ministrative Procedure Act (5 U.S.C. chap-
ter 5) does not apply to these regulations,
and because these regulations do not im-
pose a collection of information on small
entities, the Regulatory Flexibility Act (5
U.S.C. chapter 6) does not apply. Pursuant
to section 7805(f) of the Code, this regula-
tion has been submitted to the Chief Coun-
sel for Advocacy of the Small Business
Administration for comment on its impact
on small business.
Comments and Public Hearing
Before the proposed regulations are
adopted as final regulations, consideration
will be given to any comments that are
submitted timely to the IRS as prescribed
in this preamble under the “Addresses”
heading. The IRS and the Treasury De-
partment request comments on all aspects
of these proposed rules. All comments
will be available for public inspection and
copying atwww.regulations.govor upon
request.
A public hearing has been scheduled for
December 19, 2013, beginning at 10 a.m.
in the IRS Auditorium, Internal Revenue
Building, 1111 Constitution Avenue, NW.,
Washington, DC. Due to building security
procedures, visitors must enter at the Con-
stitution Avenue entrance. In addition, all
visitors must present photo identification
to enter the building. Because of access
restrictions, visitors will not be admitted
beyond the immediateentrance area more
than 30 minutes beforethe hearing starts.
For information about having your name
placed on the building access list to attend
the hearing, see the “FOR FURTHER IN-
FORMATION CONTACT” section of this
preamble.
The rules of 26 CFR 601.601(a)(3) ap-
ply to the hearing. Persons who wish to
present oral comments at the hearing must
submit electronic or written comments, an
outline of the topics to be discussed, and
the time to be devoted to each topic (signed
original and eight (8) copies) by Novem-
ber 18, 2013. A period of 10 minutes will
be allotted to each person for making com-
ments. An agenda showing the scheduling
of the speakers will be prepared after the
deadline for receivingoutlines has passed.

Par. 3. Section1.168(i)–1isamended
by revising paragraphs (a) through (l)(1),
and paragraph (m), to read as follows:
§1.168(i)–1 General asset accounts.
(a)Scope. This section provides rules
for general asset accounts under section
168(i)(4). The provisions of this section
applyonlytoassetsforwhichanelection
has been made under paragraph (l) of this
section.
(b)Definitions. For purposes of this
section, the following definitions apply:
(1)Unadjusted depreciable basishas
the same meaning given such term in
§1.168(b)–1(a)(3).
(2)Unadjusted depreciable basis of the
general asset accountis the sum of the
unadjusted depreciable bases of all assets
included in the general asset account.
(3)Adjusted depreciable basis of the
general asset accountis the unadjusted de-
preciable basis of the general asset account
less the adjustments to basis described in
section 1016(a)(2) and (3).
(4)Buildinghas the same meaning as
that term is defined in §1.48–1(e)(1).
(5)Expensed cost
is the amount of any
allowable credit or deduction treated as
a deduction allowable for depreciation or
amortization for purposes of section 1245
(for example, a creditallowable under sec-
tion 30 or a deduction allowable under sec-
tion 179, 179A, or 190). Expensed cost
does not include any additional first year
depreciation deduction.
(6)Mass assetsis a mass or group of
individual items of depreciable assets—
(i) That are not necessarily homoge-
nous;
(ii) Each of which is minor in value
relative to the total value of the mass or
group;
(iii) Numerous in quantity;
(iv) Usually accounted for only on a
total dollar or quantity basis;
(v) With respect to which separate iden-
tification is impracticable; and
(vi) Placed in service in the same tax-
able year.
(7)Portionofanassetis any part of
an asset that is less than the entire asset as
determined under paragraph (e)(2)(viii) of
this section.
(8)Remaining adjusted depreciable ba-
sisofthegeneralassetaccountis the un-
adjusted depreciable basis of the general
asset account less the amount of the addi-
tional first year depreciation deduction al-
lowed or allowable, whichever is greater,
for the general asset account.
(9)Structural componenthas the
same meaning as that term is defined in
§1.48–1(e)(2).
(c)Establishment of general asset ac-
counts—(1)Assets eligible for general as-
set accounts—(i)General rules. Assets
that are subject to either the general de-
preciation system of section 168(a) or the
alternative depreciation system of section
168(g) may be accounted for in one or
more general asset accounts. An asset is
included in a general asset account only to
the extent of the asset’s unadjusted depre-
ciable basis. However, an asset is not to be
included in a general asset account if the
asset is used both in a trade or business (or
for the production of income) and in a per-
sonal activity at any time during the tax-
able year in which the asset is placed in ser-
vice by the taxpayer or if the asset is placed
2013–43 I.R.B.409October 21, 2013

in service and disposed of during the same
taxable year.
(ii)Special rules for assets generat-
ing foreign source income. (A) Assets
that generate foreign source income, both
United States and foreign source income,
or combined gross income of a foreign
sales corporation (FSC) (as defined in for-
mer section 922), domestic international
sales corporation (DISC) (as defined in
section 992(a)), or possessions corpora-
tion (as defined in section 936) and its
related supplier may be included in a gen-
eral asset account if the requirements of
paragraph (c)(2)(i) of this section are sat-
isfied. If, however, the inclusion of these
assets in a general asset account results
in a substantial distortion of income, the
Commissioner may disregard the general
asset account election and make any real-
locations of income or expense necessary
to clearly reflect income.
(B) A general asset account shall be
treated as a single asset for purposes of
applying the rules in §1.861–9T(g)(3)
(relating to allocation and apportion-
ment of interest expense under the asset
method). A general asset account that
generates income in more than one group-
ing of income (statutory and residual)
is a multiple category asset (as defined
in §1.861–9T(g)(3)(ii)), and the income
yield from the general asset account must
be determined by applying the rules for
multiple category assets as if the general
asset account were a single asset.
(2)Grouping assets in general asset ac-
counts—(i)General rules. If a taxpayer
makes the election under paragraph (l) of
this section, assets that are subject to the
election are grouped into one or more gen-
eral asset accounts. Assets that are eligible
to be grouped into a single general asset ac-
count may be divided into more than one
general asset account. Each general asset
account must include only assets that—
(A) Have the same applicable deprecia-
tion method;
(B) Have the same applicable recovery
period;
(C) Have the same applicable conven-
tion; and
(D) Are placed in service by the tax-
payer in the same taxable year.
(ii)Special rules.Inadditiontothegen-
eral rules in paragraph (c)(2)(i) of this sec-
tion, the following rules apply when estab-
lishing general asset accounts—
(A) Assets subject to the mid-quarter
convention may only be grouped into a
general asset account with assets that are
placed in service in the same quarter of the
taxable year;
(B) Assets subject to the mid-month
convention may only be grouped into a
general asset account with assets that are
placed in service in the same month of the
taxable year;
(C) Passenger automobiles for which
the depreciation allowance is limited un-
der section 280F(a) must be grouped into
a separate general asset account;
(D) Assets not eligible for any addi-
tional first year depreciation deduction
(including assets for which the taxpayer
elected not to deduct the additional first
year depreciation) provided by, for ex-
ample, section 168(k), 168(l), 168(m),
168(n), 1400L(b), or 1400N(d), must be
grouped into a separate general asset ac-
count;
(E) Assets eligible for the additional
first year depreciation deduction may only
be grouped into a general asset account
with assets for which the taxpayer claimed
the same percentage of the additional first
year depreciation (for example, 30 percent,
50 percent, or 100 percent);
(F) Except for passenger automobiles
described in paragraph (c)(2)(ii)(C) of this
section, listed property (as defined in sec-
tion 280F(d)(4)) must be grouped into a
separate general asset account;
(G) Assets for which the depreciation
allowance for the placed-in-service year is
not determined by using an optional depre-
ciation table (for further guidance, see sec-
tion 8 of Rev. Proc. 87–57, 1987–2 C.B.
687, 693 (see §601.601(d)(2) of this chap-
ter)) must be grouped into a separate gen-
eral asset account;
(H) Mass assets that are or will be sub-
ject to paragraph (j)(2)(i)(D) of this sec-
tion (disposed of or converted mass asset
is identified by a mortality dispersion ta-
ble) must be grouped into a separate gen-
eral asset account; and
(I) Assets subject to paragraph
(h)(2)(iii)(A) of this section (change in
use results in a shorter recovery period or
a more accelerated depreciation method)
for which the depreciation allowance
for the year of change (as defined in
§1.168(i)–4(a)) is not determined by us-
ing an optional depreciation table must
be grouped into a separate general asset
account.
(3)Examples. The following exam-
ples illustrate the application of this para-
graph (c). For purposes of these exam-
ples, assume that section 168 as in effect
on September 19, 2013, applies to tax-
able years beginning on or after January 1,
2014.
Example 1. In 2014, J, a proprietorship with a cal-
endar year-end, purchases and places in service one
item of equipment that costs $550,000. This equip-
ment is section 179 property and also is 5-year prop-
erty under section 168(e). On its Federal tax return
for 2014, J makes an election under section 179 to ex-
pense $25,000 of the equipment’s cost and makes an
election under paragraph (l) of this section to include
the equipment in a generalasset account. As a result,
the unadjusted depreciable basis of the equipment is
$525,000. In accordance with paragraph (c)(1) of this
section, J must include only $525,000 of the equip-
ment’s cost in the general asset account.
Example 2. In 2014, K, a proprietorship with a
calendar year-end, purchases and places in service
100 items of equipment. All of these items are 5-year
property under section 168(e), are not listed property,
and are not eligible for any additional first year depre-
ciation deduction. On its Federal tax return for 2014,
K does not make an election under section 179 to ex-
pense the cost of any of the 100 items of equipment
and does make an election under paragraph (l) of this
section to include the 100 items of equipment in a
general asset account. K depreciates its 5-year prop-
erty placed in service in 2014 using the optional de-
preciation table that corresponds with the general de-
preciation system, the 200-percent declining balance
method, a 5-year recovery period, and the half-year
convention. In accordance with paragraph (c)(2) of
this section, K includes all of the 100 items of equip-
ment in one general asset account.
Example 3. The facts are the same as inExample
2
, except that K decides not to include all of the 100
items of equipment in one general asset account. In-
stead and in accordance with paragraph (c)(2) of this
section, K establishes 100 general asset accounts and
includes one item of equipment in each general asset
account.
Example 4. L, a calendar-year corporation, is a
wholesale distributer. In 2014, L places in service the
following properties for use in its wholesale distribu-
tion business: computers, automobiles, and forklifts.
On its Federal tax return for 2014, L does not make
an election under section 179 to expense the cost of
any of these items of equipment and does make an
election under paragraph (l) of this section to include
all of these items of equipment in a general asset ac-
count. All of these items are 5-year property under
section 168(e) and are not eligible for any additional
first year depreciation deduction. The computers are
listed property, and the automobiles are listed prop-
erty and are subject to section 280F(a). L depreciates
its 5-year property placed in service in 2014 using the
optional depreciation table that corresponds with the
general depreciation system, the 200-percent declin-
ing balance method, a 5-year recovery period, and the
half-year convention. Although the computers, auto-
mobiles, and forklifts are 5-year property, L cannot
October 21, 20134102013–43 I.R.B.

include all of them in one general asset account be-
cause the computers and automobiles are listed prop-
erty. Further, even though the computers and automo-
biles are listed property, L cannot include them in one
general asset account because the automobiles also
are subject to section 280F(a). In accordance with
paragraph (c)(2) of this section, L establishes three
general asset accounts: one for the computers, one
for the automobiles, and one for the forklifts.
Example 5. M, a fiscal-year corporation with a
taxable year ending June 30, purchases and places
in service ten items of new equipment in October
2014, and purchases and places in service five other
items of new equipment in February 2015. On its
Federal tax return for the taxable year ending June
30, 2015, M does not make an election under sec-
tion 179 to expense the cost of any of these items
of equipment and does make an election under para-
graph (l) of this section to include all of these items
of equipment in a general asset account. All of these
items of equipment are 7-year property under section
168(e), are not listed property, and are property de-
scribed in section 168(k)(2)(B). All of the ten items
of equipment placed in service in October 2014 are
eligible for the 50-percent additional first year de-
preciation deduction provided by section 168(k)(1).
All of the five items of equipment placed in service
in February 2015 are not eligible for any additional
first year depreciation deduction. M depreciates its
7-year property placed in service for the taxable year
ending June 30, 2015, using the optional depreciation
table that corresponds with the general depreciation
system, the 200-percent declining balance method, a
7-year recovery period, and the half-year convention.
Although the 15 items of equipment are depreciated
using the same depreciation method, recovery period,
and convention, M cannot include all of them in one
general asset account because some of items of equip-
ment are not eligible for any additional first year de-
preciation deduction. In accordance with paragraph
(c)(2) of this section, M establishes two general asset
accounts: one for the ten items of equipment eligible
for the 50-percent additional first year depreciation
deduction and one for the five items of equipment not
eligible for any additional first year depreciation de-
duction.
(d)Determination of depreciation al-
lowance—(1)In general. Depreciation
allowances are determined for each gen-
eral asset account. The depreciation al-
lowances must be recorded in a deprecia-
tion reserve account for each general as-
set account. The allowance for depre-
ciation under this section constitutes the
amount of depreciation allowable under
section 167(a).
(2)Assets in general asset account are
eligible for additional first year deprecia-
tion deduction. If all the assets in a gen-
eral asset account are eligible for the ad-
ditional first year depreciation deduction,
the taxpayer first must determine the al-
lowable additional first year depreciation
deduction for the general asset account for
the placed-in-service year and then must
determine the amount otherwise allowable
as a depreciation deduction for the gen-
eral asset account for the placed-in-service
year and any subsequent taxable year. The
allowable additional first year depreciation
deduction for the general asset account for
the placed-in-serviceyear is determined by
multiplying the unadjusted depreciable ba-
sis of the general asset account by the ad-
ditional first year depreciation deduction
percentage applicable to the assets in the
account (for example, 30 percent, 50 per-
cent, or 100 percent). The remaining ad-
justed depreciable basis of the general as-
set account then is depreciated using the
applicable depreciation method, recovery
period, and convention for the assets in the
account.
(3)No assets in general asset account
are eligible for additional first year depre-
ciation deduction. If none of the assets
in a general asset account are eligible for
the additional first year depreciation de-
duction, the taxpayer must determine the
allowable depreciation deduction for the
general asset account for the placed-in-
service year and any subsequent taxable
year by using the applicable depreciation
method, recovery period, and convention
for the assets in the account.
(4)Special rule for passenger automo-
biles. For purposes of applying section
280F(a), the depreciation allowance for
a general asset account established for
passenger automobiles is limited for each
taxable year to the amount prescribed in
section 280F(a) multiplied by the excess
of the number of automobiles originally
included in the account over the number of
automobiles disposed of during the taxable
year or in any prior taxable year in a trans-
action described in paragraphs (e)(3)(iii)
(disposition of an asset in a qualifying dis-
position), (e)(3)(iv) (transactions subject
to section 168(i)(7)), (e)(3)(v) (transac-
tions subject to section 1031 or section
1033), (e)(3)(vi) (technical termination
of a partnership), (e)(3)(vii) (anti-abuse
rule), (g) (assets subject to recapture),
(h)(1) (conversion topersonal use), or
(h)(2) (business or income-producing use
percentage changes) of this section.
(e)Dispositions from a general asset
account—(1)Scope and Definition—(i)
In general. This paragraph (e) provides
rules applicable to dispositions of assets
included in a general asset account. For
purposes of this paragraph (e), an asset in a
general asset account is disposed of when
ownership of the asset is transferred or
when the asset is permanently withdrawn
from use either in the taxpayer’s trade or
business or in the production of income.
A disposition includes the sale, exchange,
retirement, physical abandonment, or de-
struction of an asset. A disposition also
occurs when an asset is transferred to
a supplies, scrap, or similar account, or
when a portion of an asset is disposed of
as described in paragraph (e)(1)(ii) of this
section. If a structural component (or a
portion thereof) of a building is disposed
of in a disposition described in paragraph
(e)(1)(ii) of this section, a disposition also
includes the disposition of such structural
component (or such portion thereof).
(ii)Disposition of a portion of an asset.
For purposes of applying paragraph (e) of
this section, a disposition includes a dispo-
sition of a portion of an asset in a general
asset account as a resultof a casualty event
described in section 165, a disposition of a
portion of an asset in a general asset ac-
count for which gain (determined without
regard to section 1245 or section 1250) is
not recognized in whole or in part under
section 1031 or section 1033, a transfer of
a portion of an asset in a general asset ac-
count in a transaction described in section
168(i)(7)(B), a sale of a portion of an as-
set in a general asset account, or a dispo-
sition of a portion of an asset in a gen-
eral asset account in a transaction is de-
scribed in paragraph (e)(3)(vii)(B) of this
section. For other transactions, a dispo-
sition includes a disposition of a portion
of an asset in a general asset account only
if the taxpayer makes the election under
paragraph (e)(3)(ii) of this section to ter-
minate the general asset account in which
that disposed portion is included or makes
the election under paragraph (e)(3)(iii) of
this section for that disposed portion.
(2)General rules for a disposition—(i)
No immediate recovery of basis. Except
as provided in paragraph (e)(3) of this sec-
tion, immediately before a disposition of
any asset in a general asset account or a
disposition of a portion of such asset as de-
scribed in paragraph (e)(1)(ii) of this sec-
tion, the asset or the portion of the as-
set, as applicable, is treated as having an
adjusted depreciable basis (as defined in
§1.168(b)–1(a)(4)) of zero for purposes of
section 1011. Therefore, no loss is realized
upon the disposition of an asset from the
2013–43 I.R.B.411October 21, 2013

general asset account or upon the disposi-
tion of a portion of such asset as described
in paragraph (e)(1)(ii) of this section. Sim-
ilarly, where an asset or a portion of an as-
set, as applicable, is disposed of by transfer
to a supplies, scrap, or similar account, the
basis of the asset or the portion of the as-
set, as applicable, in the supplies, scrap, or
similar account will be zero.
(ii)Treatment of amount realized.Any
amount realized on a disposition is recog-
nized as ordinary income (notwithstand-
ing any other provision of subtitle A of
the Internal Revenue Code) to the extent
the sum of the unadjusted depreciable ba-
sis of the general asset account and any ex-
pensed cost (as defined in paragraph (b)(5)
of this section) for assets in the account ex-
ceeds any amounts previously recognized
as ordinary income upon the disposition of
other assets in the account or upon the dis-
position of portions of such assets as de-
scribed in paragraph (e)(1)(ii) of this sec-
tion. The recognition and character of any
excess amount realized are determined un-
der other applicable provisions of the In-
ternal Revenue Code (other than sections
1245 and 1250 or provisions of the Internal
Revenue Code that treat gain on a disposi-
tion as subject to section 1245 or 1250).
(iii)Effect of disposition on a general
asset account. Except as provided in para-
graph (e)(3) of this section, the unadjusted
depreciable basis and the depreciation re-
serve of the general asset account are not
affected as a result of a disposition of an
asset from the general asset account or of a
disposition of a portion of such asset as de-
scribed in paragraph (e)(1)(ii) of this sec-
tion.
(iv)Coordination with nonrecognition
provisions. For purposes of determining
the basis of an asset or a portion of an
asset, as applicable, acquired in a trans-
action, other than a transaction described
in paragraphs (e)(3)(iv) (pertaining to
transactions subjectto section 168(i)(7)),
(e)(3)(v) (pertaining to transactions sub-
ject to section 1031 or section 1033), and
(e)(3)(vi) (pertaining to technical termi-
nations of partnerships) of this section, to
which a nonrecognition section of the In-
ternal Revenue Code applies (determined
without regard to this section), the amount
of ordinary income recognized under this
paragraph (e)(2) is treated as the amount
of gain recognized on the disposition.
(v)Manner of disposition. The man-
ner of disposition (for example, normal
retirement, abnormal retirement, ordinary
retirement, or extraordinary retirement)
is not taken into account in determining
whether a disposition occurs or gain or
loss is recognized.
(vi)Disposition by transfer to a sup-
plies account. If a taxpayer made an
election under §1.162–3(d) to treat the
cost of any rotable spare part, temporary
spare part, or standby emergency spare
part (as defined in §1.162–3(c)) as a cap-
ital expenditure subject to the allowance
for depreciation and also made an election
under paragraph (l) of this section to in-
clude that rotable, temporary, or standby
emergency spare part in a general as-
set account, the taxpayer can dispose of
the rotable, temporary, or standby emer-
gency spare part by transferring it to a
supplies account only if the taxpayer has
obtained the consent of the Commissioner
to revoke the §1.162–3(d) election. See
§1.162–3(d)(3) for the procedures for re-
voking a §1.162–3(d) election.
(vii)Leasehold improvements.The
rules of paragraph (e) of this section also
apply to—
(A) A lessor of leased property that
made an improvement to that property for
the lessee of the property, has a depreciable
basis in the improvement, made an elec-
tion under paragraph (l) of this section to
include the improvement in a general asset
account, and disposesof the improvement
(or disposes of a portion of the improve-
ment as described in paragraph (e)(1)(ii) of
this section) before orupon the termination
of the lease with the lessee. See section
168(i)(8)(B); and
(B) A lessee of leased property that
made an improvement to that property, has
a depreciable basis in the improvement,
made an election under paragraph (l) of
this section to include the improvement in
a general asset account, and disposes of the
improvement (or disposes of a portion of
the improvement as described in paragraph
(e)(1)(ii) of this section) before or upon the
termination of the lease.
(viii)Determination of asset disposed
of—(A)General rules. For purposes of ap-
plying paragraph (e) of this section to the
disposition of an asset in a general asset
account (instead of the disposition of the
general asset account), the facts and cir-
cumstances of each disposition are consid-
ered in determining what is the appropri-
ate asset disposed of. The asset for dis-
position purposes may not consist of items
placed in service by the taxpayer on dif-
ferent dates. For purposes of determin-
ing what is the appropriate asset disposed
of, the unit of property determination un-
der §1.263(a)–3(e) or in published guid-
ance in the Internal Revenue Bulletin un-
der section 263(a) (see §601.601(d)(2) of
this chapter) does not apply.
(B)Special rules. In addition to the
general rules in paragraph (e)(2)(viii)(A)
of this section, the following rules apply
for purposes of applying paragraph (e) of
this section to the disposition of an asset
in a general asset account (instead of the
disposition of the general asset account):
(1) Each building (including its struc-
tural components) is the asset except
as provided in §1.1250–1(a)(2)(ii) or in
paragraph (e)(2)(viii)(B)(2) or paragraph
(e)(2)(viii) (B)(4)ofthissection.
(2) If a building has two or more con-
dominium or cooperative units, each con-
dominium or cooperative unit (including
its structural components) is the asset ex-
cept as provided in §1.1250–1(a)(2)(ii) or
in paragraph (e)(2)(viii)(B)(4) of this sec-
tion.
(3) If a taxpayer properly includes an
item in one of the asset classes 00.11
through 00.4 of Rev. Proc. 87–56 (1987–2
C.B. 674) (see §601.601(d)(2) of this chap-
ter) or properly classifies an item in one of
the categories under section 168(e)(3) (ex-
cept for a category that includes buildings
or structural components; for example,
retail motor fuels outlet, qualified lease-
hold improvement property, qualified
restaurant property, and qualified retail
improvement property), each item is the
asset provided paragraph (e)(2)(viii)(B)(4)
of this section does not apply to the item.
For example, each desk is the asset, each
computer is the asset, and each qualified
smart electric meter is the asset.
(4) If the taxpayer places in service an
improvement or addition to an asset after
the taxpayer placed the asset in service,
the improvement or addition is a separate
asset.
(ix)Examples. The following exam-
ples illustrate the application of this para-
graph (e)(2). For purposes of these ex-
amples, assume that section 168 as in ef-
fect on September 19, 2013, applies to tax-
October 21, 20134122013–43 I.R.B.

able years beginning on or after January 1,
2014.
Example 1. A, a calendar-year partnership, main-
tains one general asset account for one office build-
ing that cost $10 million. A discovers a leak in the
roof of the building and decides to replace the entire
roof. The roof is a structural component of the build-
ing. In accordance with paragraph (e)(2)(viii)(B)(
1)
of this section, the office building (including its struc-
tural components) is the asset for disposition pur-
poses. The retirement of the replaced roof is not a dis-
position of a portion of an asset as described in para-
graph (e)(1)(ii) of this section. Thus, the retirement
of the replaced roof is not a disposition under para-
graph (e)(1) of this section. As a result, A continues
to depreciate the $10 million cost of the general as-
set account. If A must capitalize the amount paid for
the replacement roof pursuant to §1.263(a)–3, the re-
placement roof is a separate asset for disposition pur-
poses pursuant to paragraph (e)(2)(viii)(B)(
4)ofthis
section and for depreciation purposes pursuant to sec-
tion 168(i)(6).
Example 2. B, a calendar-year commercial air-
line company, maintains one general asset account
for five aircraft that cost a total of $500 million.
These aircraft are described in asset class 45.0 of
Rev. Proc. 87–56. B replaces the existing engines on
one of the aircraft with new engines. Assume each
aircraft is a unit of property as determined under
§1.263(a)–3(e)(3) and each engine of an aircraft is
a major component or substantial structural part of
the aircraft as determined under §1.263(a)–3(k)(6).
Assume also that B treats each aircraft as the asset for
disposition purposes in accordance with paragraph
(e)(2)(viii) of this section. The retirement of the
replaced engines is not a disposition of a portion of
an asset as described in paragraph (e)(1)(ii) of this
section. Thus, the retirement of the replaced engines
is not a disposition under paragraph (e)(1) of this
section. As a result, B continues to depreciate the
$500 million cost of the general asset account. If B
must capitalize the amount paid for the replacement
engines pursuant to §1.263(a)–3, the replacement
engines are a separate asset for disposition purposes
pursuant to paragraph (e)(2)(viii)(B)(
4)ofthissec-
tion and for depreciation purposes pursuant to section
168(i)(6).
Example 3. (i) R, a calendar-year corporation,
maintains one general asset account for ten machines.
The machines cost a total of $10,000 and are placed
in service in June 2014. Of the ten machines, one
machine costs $8,200 and nine machines cost a to-
tal of $1,800. Assume R depreciates this general as-
set account using the optional depreciation table that
corresponds with the general depreciation system, the
200-percent declining balance method, a 5-year re-
covery period, and a half-year convention. R does
not make a section 179 election for any of the ma-
chines, and all of the machines are not eligible for
any additional first year depreciation deduction. As
of January 1, 2015, the depreciation reserve of the ac-
count is $2,000 ($10,000 x 20%).
(ii) On February 8, 2015, R sells the machine that
cost $8,200 to an unrelated party for $9,000. Under
paragraph (e)(2)(i) of this section, this machine has
an adjusted depreciable basis of zero.
(iii) On its 2015 tax return, R recognizes the
amount realized of $9,000 as ordinary income
because such amount does not exceed the unad-
justed depreciable basis of the general asset account
($10,000), plus any expensed cost for assets in the
account ($0), less amounts previously recognized
as ordinary income ($0). Moreover, the unadjusted
depreciable basis and depreciation reserve of the
account are not affected by the disposition of the
machine. Thus, the depreciation allowance for the
account in 2015 is $3,200 ($10,000 x 32%).
Example 4. (i) The facts are the same as inEx-
ample 3
. In addition, on June 4, 2016, R sells seven
machines to an unrelated party for a total of $1,100.
In accordance with paragraph (e)(2)(i) of this section,
these machines have an adjusted depreciable basis of
zero.
(ii) On its 2016 tax return, R recognizes $1,000
as ordinary income (the unadjusted depreciable ba-
sis of $10,000, plus the expensed cost of $0, less
the amount of $9,000 previously recognized as ordi-
nary income). The recognition and character of the
excess amount realized of $100 ($1,100-$1,000) are
determined under applicable provisions of the Inter-
nal Revenue Code other than section 1245 (such as
section 1231). Moreover, the unadjusted depreciable
basis and depreciation reserve of the account are not
affected by the disposition of the machines. Thus,
the depreciation allowance for the account in 2016 is
$1,920 ($10,000 x 19.2%).
(3)Special rules—(i)In general.This
paragraph (e)(3) provides the rules for ter-
minating general asset account treatment
upon certain dispositions. While the rules
under paragraphs (e)(3)(ii) and (iii) of this
section are optional rules, the rules under
paragraphs (e)(3)(iv), (v), (vi), and (vii) of
this section are mandatory rules. A tax-
payer elects to apply paragraph (e)(3)(ii)
or paragraph (e)(3)(iii) of this section by
reporting the gain, loss, or other deduction
on the taxpayer’s timely filed original Fed-
eral tax return (including extensions) for
the taxable year in which the disposition
occurs. A taxpayer may revoke the elec-
tion to apply paragraph (e)(3)(ii) or para-
graph (e)(3)(iii) of this section only by fil-
ing a request for a private letter ruling and
obtaining the Commissioner’s consent to
revoke the election. The Commissioner
may grant a request to revoke this elec-
tion if the taxpayer acted reasonably and
in good faith, and the revocation will not
prejudice the interests of the Government.
See generally §301.9100–3 of this chapter.
The election to apply paragraph (e)(3)(ii)
or (iii) of this section may not be made or
revoked through the filing of an applica-
tion for change in accounting method. For
purposes of applying paragraph (e)(3)(iii)
through (vii) of this section, see paragraph
(j) of this section for identifying an as-
set disposed of and its unadjusted depre-
ciable basis. Solely for purposes of ap-
plying paragraphs (e)(3)(iii), (e)(3)(iv)(C),
(e)(3)(v)(B), and (e)(3)(vii) of this section,
the termassetis:
(A) The asset as determined under para-
graph (e)(2)(viii) of this section, or
(B) The portion of such asset that is
disposed of in a disposition described in
paragraph (e)(1)(ii) of this section.
(ii)Disposition of all assets remain-
ing in a general asset account—(A)Op-
tional termination of a general asset ac-
count. Upon the disposition of all of the
assets, the last asset, or the remaining por-
tion of the last asset, in a general asset
account, a taxpayer may apply this para-
graph (e)(3)(ii) to recover the adjusted de-
preciable basis of the general asset ac-
count (rather than having paragraph (e)(2)
of this section apply). Under this para-
graph (e)(3)(ii), the general asset account
terminates and the amount of gain or loss
for the general asset account is determined
under section 1001(a) by taking into ac-
count the adjusted depreciable basis of the
general asset account at the time of the dis-
position (as determined under the appli-
cable convention for the general asset ac-
count). The recognition and character of
the gain or loss are determined under other
applicable provisions of the Internal Rev-
enue Code, except that the amount of gain
subject to section 1245 (or section 1250)
is limited to the excess of the depreciation
allowed or allowable for the general asset
account, including any expensed cost (or
the excess of the additional depreciation
allowed or allowable for the general as-
set account), over any amounts previously
recognized as ordinary income under para-
graph (e)(2) of this section.
(B)Examples. The following exam-
ples illustrate the application of this para-
graph (e)(3)(ii). For purposes of these ex-
amples, assume that section 168 as in ef-
fect on September 19, 2013, applies to tax-
able years beginning on or after January 1,
2014.
Example 1. (i) T, a calendar-year corporation,
maintains a general asset account for 1,000 calcula-
tors. The calculators cost a total of $60,000 and are
placed in service in 2014. Assume T depreciates this
general asset account using the optional depreciation
table that corresponds with the general depreciation
system, the 200-percent declining balance method, a
5-year recovery period, and a half-year convention.
T does not make a section 179 election for any of the
calculators, and all of the calculators are not eligible
for any additional first year depreciation deduction.
In 2015, T sells 200 of the calculators to an unre-
lated party for a total of $10,000 and recognizes the
2013–43 I.R.B.413October 21, 2013

$10,000 as ordinary income in accordance with para-
graph (e)(2) of this section.
(ii) On March 26, 2016, T sells the remaining
calculators in the general asset account to an unre-
lated party for $35,000. T elects to apply paragraph
(e)(3)(ii) of this section. As a result, the account ter-
minates and gain or loss is determined for the account.
(iii) On the date of disposition, the adjusted de-
preciable basis of the account is $23,040 (unadjusted
depreciable basis of $60,000 less the depreciation al-
lowed or allowable of $36,960). Thus, in 2016, T rec-
ognizes gain of $11,960 (amount realized of $35,000
less the adjusted depreciable basis of $23,040). The
gain of $11,960 is subject to section 1245 to the ex-
tent of the depreciation allowed or allowable for the
account (plus the expensed cost for assets in the ac-
count) less the amounts previously recognized as or-
dinary income ($36,960 + $0 - $10,000 = $26,960).
As a result, the entire gain of $11,960 is subject to
section 1245.
Example 2. (i) J, a calendar-year corporation,
maintains a general asset account for one item of
equipment. This equipment costs $2,000 and is
placed in service in 2014. Assume J depreciates this
general asset account using the optional depreciation
table that corresponds with the general depreciation
system, the 200-percent declining balance method,
a 5-year recovery period, and a half-year conven-
tion. J does not make a section 179 election for the
equipment, and it is not eligible for any additional
first year depreciation deduction. In June 2016, J
sells the equipment to an unrelated party for $1,000.
J elects to apply paragraph (e)(3)(ii) of this section.
As a result, the account terminates and gain or loss is
determined for the account.
(ii) On the date of disposition, the adjusted depre-
ciable basis of the account is $768 (unadjusted depre-
ciable basis of $2,000 less the depreciation allowed
or allowable of $1,232). Thus, in 2016, J recognizes
gain of $232 (amount realized of $1,000 less the ad-
justed depreciable basis of $768). The gain of $232 is
subject to section 1245 to the extent of the deprecia-
tion allowed or allowable for the account (plus the ex-
pensed cost for assets in the account) less the amounts
previously recognized as ordinary income ($1,232 +
$0 - $0 = $1,232). As a result, the entire gain of $232
is subject to section 1245.
(iii)Disposition of an asset in a qual-
ifying disposition—(A)Optional deter-
mination of the amount of gain, loss, or
other deduction. In the case of a quali-
fying disposition (described in paragraph
(e)(3)(iii)(B) of this section) of an as-
set, a taxpayer may elect to apply this
paragraph (e)(3)(iii) (rather than having
paragraph (e)(2) of this section apply).
Under this paragraph (e)(3)(iii), general
asset account treatment for the asset ter-
minates as of the first day of the taxable
year in which the qualifying disposition
occurs, and the amount of gain, loss, or
other deduction for the asset is determined
under §1.168(i)–8 or §1.168(i)–8T, as ap-
plicable, by taking into account the asset’s
adjusted depreciable basis at the time of
the disposition. The adjusted depreciable
basis of the asset at the time of the dispo-
sition (as determined under the applicable
convention for the general asset account in
which the asset was included) equals the
unadjusted depreciable basis of the asset
less the depreciation allowed or allowable
for the asset, computed by using the de-
preciation method, recovery period, and
convention applicable to the general asset
account in which the asset was included
and by including the portion of the ad-
ditional first year depreciation deduction
claimed for the general asset account that
is attributable to the asset disposed of. The
recognition and character of the gain, loss,
or other deduction are determined under
other applicable provisions of the Internal
Revenue Code, except that the amount of
gain subject to section 1245 (or section
1250) is limited to the lesser of—
(1) The depreciation allowed or allow-
able for the asset, including any expensed
cost (or the additional depreciation al-
lowed or allowable) for the asset; or
(2) The excess of—
(i) The original unadjusted depreciable
basis of the general asset account plus, in
the case of section 1245 property origi-
nally included in the general asset account,
any expensed cost; over
(ii) The cumulative amounts of gain
previously recognized as ordinary income
under either paragraph (e)(2) of this sec-
tion or section 1245 (or section 1250).
(B)Qualifying dispositions.Aquali-
fying dispositionis a disposition that does
not involve all the assets, or the last asset,
remaining in a general asset account and
that is—
(1) A direct result of a fire, storm, ship-
wreck, or other casualty, or from theft;
(2) A charitable contribution for which
a deduction is allowable under section 170;
(3) A direct result of a cessation, ter-
mination, or disposition of a business,
manufacturing or other income producing
process, operation, facility, plant, or other
unit (other than by transfer to a supplies,
scrap, or similar account); or
(4) A transaction, other than a transac-
tion described in paragraph (e)(3)(iv) (per-
taining to transactions subject to section
168(i)(7)), (v) (pertaining to transactions
subject to section 1031 or section 1033),
(vi) (pertaining to technical terminations
of partnerships), or (vii) (anti-abuse rule)
of this section, to which a nonrecognition
section of the Internal Revenue Code ap-
plies (determined without regard to this
section).
(C)Effect of a qualifying disposition on
a general asset account. If the taxpayer
elects to apply this paragraph (e)(3)(iii) to
a qualifying disposition of an asset, then—
(1) The asset is removed from the gen-
eral asset account as of the first day of the
taxable year in which the qualifying dis-
position occurs. For that taxable year, the
taxpayer accounts for the asset in a single
asset account in accordance with the rules
under §1.168(i)–7(b) or §1.168(i)–7T(b),
as applicable;
(2) The unadjusted depreciable basis of
the general asset account is reduced by the
unadjusted depreciable basis of the asset as
of the first day of the taxable year in which
the disposition occurs;
(3) The depreciation reserve of the gen-
eral asset account is reduced by the de-
preciation allowed or allowable for the as-
set as of the end of the taxable year im-
mediately preceding the year of disposi-
tion, computed by using the depreciation
method, recovery period, and convention
applicable to the general asset account in
which the asset was included and by in-
cluding the portion of the additional first
year depreciation deduction claimed for
the general asset accountthat is attribut-
able to the asset disposed of; and
(4) For purposes of determining the
amount of gain realized on subsequent dis-
positions that is subject to ordinary income
treatment under paragraph (e)(2)(ii) of this
section, the amount of any expensed cost
with respect to the asset is disregarded.
(D)Examples. The following exam-
ples illustrate the application of this para-
graph (e)(3)(iii). For purposes of these ex-
amples, assume that section 168 as in ef-
fect on September 19, 2013, applies to tax-
able years beginning on or after January 1,
2014.
Example 1. (i) Z, a calendar-year corporation,
maintains one general asset account for 12 machines.
Each machine costs $15,000 and is placed in service
in 2014. Of the 12 machines, nine machines that cost
a total of $135,000 are used in Z’s Kentucky plant,
and three machines that cost a total of $45,000 are
used in Z’s Ohio plant. Assume Z depreciates this
general asset account using the optional depreciation
table that corresponds with the general depreciation
system, the 200-percent declining balance method, a
5-year recovery period, and the half-year convention.
Z does not make a section 179 election for any of the
machines, and all of the machines are not eligible for
any additional first year depreciation deduction. As
October 21, 20134142013–43 I.R.B.

of December 31, 2015, the depreciation reserve for
the account is $93,600.
(ii) On May 27, 2016, Z sells its entire manufac-
turing plant in Ohio to an unrelated party. The sales
proceeds allocated to each of the three machines at
the Ohio plant is $5,000. This transaction is a quali-
fying disposition under paragraph (e)(3)(iii)(B)(
3)of
this section and Z elects to apply paragraph (e)(3)(iii)
of this section.
(iii) For Z’s 2016 return, the depreciation al-
lowance for the account is computed as follows. As
of December 31, 2015, the depreciation allowed or
allowable for the three machines at the Ohio plant is
$23,400. Thus, as of January 1, 2016, the unadjusted
depreciable basis of the account is reduced from
$180,000 to $135,000 ($180,000 less the unadjusted
depreciable basis of $45,000 for the three machines),
and, as of December 31, 2015, the depreciation
reserve of the account is decreased from $93,600 to
$70,200 ($93,600 less the depreciation allowed or
allowable of $23,400 for the three machines as of
December 31, 2015). Consequently, the deprecia-
tion allowance for the account in 2016 is $25,920
($135,000 x 19.2%).
(iv) For Z’s 2016 return, gain or loss for each of
the three machines at the Ohio plant is determined
as follows. The depreciation allowed or allowable in
2016 for each machine is $1,440 (($15,000 x 19.2%)/
2). Thus, the adjusted depreciable basis of each ma-
chine under section 1011 is $5,760 (the adjusted de-
preciable basis of $7,200 removed from the account
less the depreciation allowed or allowable of $1,440
in 2016). As a result, the loss recognized in 2016 for
each machine is $760 ($5,000 - $5,760), which is sub-
ject to section 1231.
Example 2. (i) A, a calendar-year partnership,
maintains one general asset account for one office
building that cost $20 million and was placed in
service in July 2011. A depreciates this general asset
account using the optional depreciation table that
corresponds with the general depreciation system,
the straight-line method, a 39-year recovery period,
and the mid-month convention. As of January 1,
2014, the depreciation reserve for the account is
$1,261,000.
(ii) In May 2014, a tornado occurs where the
building is located and damages the roof of the
building. A decides to replace the entire roof. The
roof is replaced in June 2014. The roof is a structural
component of the building. Because the roof was
damaged as a result of a casualty event described
in section 165, the partial disposition rule provided
under paragraph (e)(1)(ii) of this section applies to
the roof. Although the office building (including its
structural components) is the asset for disposition
purposes, the partial disposition rule provides that
the retirement of the replaced roof is a disposition
under paragraph (e)(1) of this section. This retire-
ment is a qualifying disposition under paragraph
(e)(3)(iii)(B)(
1) of this section and A elects to apply
paragraph (e)(3)(iii) of this section for the retirement
of the damaged roof.
(iii) Of the $20 million cost of the office building,
assume $1 million is the cost of the retired roof.
(iv) For A’s 2014 return, the depreciation al-
lowance for the account is computed as follows.
As of December 31, 2013, the depreciation allowed
or allowable for the retired roof is $63,050. Thus,
as of January 1, 2014, the unadjusted depreciable
basis of the account is reduced from $20,000,000 to
$19,000,000 ($20,000,000 less the unadjusted depre-
ciable basis of $1,000,000 for the retired roof), and
the depreciation reserveof the account is decreased
from $1,261,000 to $1,197,950 ($1,261,000 less the
depreciation allowed or allowable of $63,050 for the
retired roof as of December 31, 2013). Consequently,
the depreciation allowance for the account in 2014 is
$487,160 ($19,000,000 x 2.564%).
(v) For A’s 2014 return, gain or loss for the re-
tired roof is determined as follows. The deprecia-
tion allowed or allowable in 2014 for the retired roof
is $11,752 (($1,000,000 x 2.564%) x 5.5/12). Thus,
the adjusted depreciable basis of the retired roof un-
der section 1011 is $925,198 (the adjusted deprecia-
ble basis of $936,950 removed from the account less
the depreciation allowed or allowable of $11,752 in
2014). As a result, the loss recognized in 2014 for
the retired roof is $925,198, which is subject to sec-
tion 1231.
(vi) If A must capitalize the amount paid for the
replacement roof under §1.263(a)–3, the replacement
roof is a separate asset for depreciation purposes pur-
suant to section 168(i)(6). If A includes the replace-
ment roof in a general asset account, the replacement
roof is a separate asset for disposition purposes pur-
suant to paragraph (e)(2)(viii)(B)(
4) of this section. If
A includes the replacement roof in a single asset ac-
count or a multiple asset account under §1.168(i)–7,
the replacement roof is a separate asset for disposi-
tion purposes pursuant to §1.168(i)–8(c)(4)(ii)(D).
(iv)Transactions subject to section
168(i)(7)—(A)In general. If a taxpayer
transfers one or more assets in a gen-
eral asset account (or a portion of such
asset) in a transaction described in sec-
tion 168(i)(7)(B) (pertaining to treatment
of transferees in certain nonrecognition
transactions), the taxpayer (the transferor)
and the transferee must apply this para-
graph (e)(3)(iv) to the asset (or the portion
of such asset) (instead of applying para-
graph (e)(2), (e)(3)(ii), or (e)(3)(iii) of this
section). The transferee is bound by the
transferor’s election under paragraph (l)
of this section for the portion of the trans-
feree’s basis in the asset (or the portion of
such asset) that does not exceed the trans-
feror’s adjusted depreciable basis of the
general asset account or the asset (or the
portion of such asset), as applicable (as de-
termined under paragraph (e)(3)(iv)(B)(2)
or paragraph (e)(3)(iv)(C)(2) of this sec-
tion, as applicable).
(B)All assets remaining in general as-
set account are transferred. If a taxpayer
transfers all the assets, the last asset, or
the remaining portion of the last asset, in
a general asset account in a transaction de-
scribed in section 168(i)(7)(B)—
(1) The taxpayer (the transferor) must
terminate the general asset account on the
date of the transfer. The allowable depre-
ciation deduction for the general asset ac-
count for the transferor’s taxable year in
which the section 168(i)(7)(B) transaction
occurs is computed by using the depreci-
ation method, recovery period, and con-
vention applicable to the general asset ac-
count. This allowable depreciation deduc-
tion is allocated between the transferor and
the transferee on a monthly basis. This
allocation is made in accordance with the
rules in §1.168(d)–1(b)(7)(ii) for allocat-
ing the depreciation deduction between the
transferor and the transferee;
(2) The transferee must establish a new
general asset account for all the assets,
the last asset, or the remaining portion
of the last asset, in the taxable year in
which the section 168(i)(7)(B) transaction
occurs for the portion of its basis in the
assets that does not exceed the transferor’s
adjusted depreciable basis of the general
asset account in which all the assets, the
last asset, or the remaining portion of the
last asset, were included. The transferor’s
adjusted depreciable basis of this gen-
eral asset account is equal to the adjusted
depreciable basis of that account as of
the beginning of the transferor’s taxable
year in which the transaction occurs, de-
creased by the amount of depreciation
allocable to the transferor for the year of
the transfer (as determined under para-
graph (e)(3)(iv)(B)(1) of this section). The
transferee is treated as the transferor for
purposes of computing the allowable de-
preciation deduction for the new general
asset account under section 168. The new
general asset account must be established
in accordance with the rules in paragraph
(c) of this section, except that the unad-
justed depreciable bases of all the assets,
the last asset, or the remaining portion of
the last asset, and the greater of the de-
preciation allowed or allowable for all the
assets, the last asset, or the remaining por-
tion of the last asset (including the amount
of depreciation for the transferred assets
that is allocable to the transferor for the
year of the transfer), are included in the
newly established general asset account.
Consequently, this general asset account
in the year of the transfer will have a be-
ginning balance for both the unadjusted
depreciable basis and the depreciation re-
serve of the general asset account; and
(3) For purposes of section 168 and this
section, the transferee treats the portion
of its basis in the assets that exceeds the
2013–43 I.R.B.415October 21, 2013

transferor’s adjusted depreciable basis of
the general asset account in which all the
assets, the last asset, or the remaining por-
tion of the last asset, were included (as de-
termined under paragraph (e)(3)(iv)(B)(2)
of this section) as a separate asset that
the transferee placed in service on the
date of the transfer. The transferee ac-
counts for this asset under §1.168(i)–7 or
§1.168(i)–7T, as applicable, or may make
an election under paragraph (l) of this sec-
tion to include the asset in a general asset
account.
(C)Not all assets remaining in general
asset account are transferred. If a taxpayer
transfers an asset in a general asset ac-
count in a transaction described in section
168(i)(7)(B) and if paragraph (e)(3)(iv)(B)
of this section does not apply to this as-
set—
(1) The taxpayer (the transferor) must
remove the transferred asset from the gen-
eral asset account in which the asset is
included, as of the first day of the taxable
year in which the section 168(i)(7)(B)
transaction occurs. In addition, the ad-
justments to the general asset account
described in paragraphs (e)(3)(iii)(C)(2)
through (4) of this section must be made.
The allowable depreciation deduction for
the asset for the transferor’s taxable year
in which the section 168(i)(7)(B) trans-
action occurs is computed by using the
depreciation method, recovery period, and
convention applicable to the general asset
account in which the asset was included.
This allowable depreciation deduction is
allocated between the transferor and the
transferee on a monthly basis. This alloca-
tion is made in accordance with the rules
in §1.168(d)–1(b)(7)(ii) for allocating the
depreciation deduction between the trans-
feror and the transferee;
(2) The transferee must establish a
new general asset account for the asset
in the taxable year in which the section
168(i)(7)(B) transaction occurs for the
portion of its basis in the asset that does
not exceed the transferor’s adjusted depre-
ciable basis of the asset. The transferor’s
adjusted depreciable basis of this asset is
equal to the adjusted depreciable basis of
the asset as of the beginning of the trans-
feror’s taxable year in which the trans-
action occurs, decreased by the amount
of depreciation allocable to the transferor
for the year of the transfer (as determined
under paragraph (e)(3)(iv)(C)(1)ofthis
section). The transferee is treated as the
transferor for purposes of computing the
allowable depreciation deduction for the
new general asset account under section
168. The new general asset account must
be established in accordance with the rules
in paragraph (c) of this section, except
that the unadjusted depreciable basis of
the asset, and the greater of the depreci-
ation allowed or allowable for the asset
(including the amount of depreciation for
the transferred asset that is allocable to the
transferor for the year of the transfer), are
included in the newly established general
asset account. Consequently, this general
asset account in the year of the transfer
will have a beginning balance for both
the unadjusted depreciable basis and the
depreciation reserve of the general asset
account; and
(3) For purposes of section 168 and this
section, the transferee treats the portion
of its basis in the asset that exceeds the
transferor’s adjusteddepreciable basis of
the asset (as determined under paragraph
(e)(3)(iv)(C)(2) of this section) as a sep-
arate asset that the transferee placed in
service on the date of the transfer. The
transferee accounts for this asset under
§1.168(i)–7 or §1.168(i)–7T, as appli-
cable, or may make an election under
paragraph (l) of this section to include the
asset in a general asset account.
(v)Transactions subject to section
1031 or section 1033—(A)Like-kind ex-
change or involuntary conversion of all
assets remaining in a general asset ac-
count. If all the assets, the last asset, or
the remaining portion of the last asset,
in a general asset account are transferred
by a taxpayer in a like-kind exchange (as
defined under §1.168–6(b)(11)) or in an
involuntary conversion (as defined under
§1.168–6(b)(12)), the taxpayer must ap-
ply this paragraph (e)(3)(v)(A) (instead
of applying paragraph (e)(2), (e)(3)(ii),
or (e)(3)(iii) of this section). Under this
paragraph (e)(3)(v)(A), the general as-
set account terminates as of the first day
of the year of disposition (as defined in
§1.168(i)–6(b)(5)) and—
(1) The amount of gain or loss for the
general asset account is determined under
section 1001(a) by taking into account the
adjusted depreciable basis of the general
asset account at the time of disposition
(as defined in §1.168(i)–6(b)(3)). The
depreciation allowance for the general
asset account in the year of disposition
is determined in the same manner as
the depreciation allowance for the relin-
quished MACRS property (as defined in
§1.168(i)–6(b)(2)) in the year of dispo-
sition is determined under §1.168(i)–6.
The recognition and character of gain or
loss are determined in accordance with
paragraph (e)(3)(ii)(A) of this section
(notwithstanding thatparagraph (e)(3)(ii)
of this section is an optional rule); and
(2) The adjusted depreciable basis of
the general asset account at the time of dis-
position is treated as the adjusted depre-
ciable basis of the relinquished MACRS
property.
(B)Like-kind exchange or involuntary
conversion of less than all assets remain-
ing in a general asset account. If an asset
in a general asset account is transferred
by a taxpayer in a like-kind exchange or
in an involuntary conversion and if para-
graph (e)(3)(v)(A) of this section does
not apply to this asset, the taxpayer must
apply this paragraph (e)(3)(v)(B) (instead
of applying paragraph (e)(2), (e)(3)(ii), or
(e)(3)(iii) of this section). Under this para-
graph (e)(3)(v)(B), general asset account
treatment for the asset terminates as of
the first day of the year of disposition (as
defined in §1.168(i)–6(b)(5)), and—
(1) The amount of gain or loss for the
asset is determined bytaking into account
the asset’s adjusted depreciable basis at
the time of disposition (as defined in
§1.168(i)–6(b)(3)). The adjusted depre-
ciable basis of the asset at the time of dis-
position equals the unadjusted depreciable
basis of the asset less the depreciation
allowed or allowable for the asset, com-
puted by using the depreciation method,
recovery period, and convention applica-
ble to the general asset account in which
the asset was included and by including
the portion of the additional first year
depreciation deduction claimed for the
general asset account thatis attributable to
the relinquished asset. The depreciation
allowance for the asset in the year of dis-
position is determined in the same manner
as the depreciation allowance for the re-
linquished MACRS property (as defined
in §1.168(i)–6(b)(2)) in the year of dis-
position is determined under §1.168(i)–6.
The recognition and character of the gain
or loss are determined in accordance with
paragraph (e)(3)(iii)(A) of this section
October 21, 20134162013–43 I.R.B.

(notwithstanding thatparagraph (e)(3)(iii)
of this section is an optional rule); and
(2) As of the first day of the year of dis-
position, the taxpayer must remove the re-
linquished asset from the general asset ac-
count and make the adjustments to the gen-
eral asset account described in paragraphs
(e)(3)(iii)(C)(2) through (4) of this section.
(vi)Technical termination of a part-
nership. In the case of a technical ter-
mination of a partnership under section
708(b)(1)(B), the terminated partner-
ship must apply this paragraph (e)(3)(vi)
(instead of applying paragraph (e)(2),
(e)(3)(ii), or (e)(3)(iii) of this section).
Under this paragraph (e)(3)(vi), all of
the terminated partnership’s general asset
accounts terminate as of the date of its
termination under section 708(b)(1)(B).
The terminated partnership computes the
allowable depreciation deduction for each
of its general asset accounts for the taxable
year in which the technical termination
occurs by using the depreciation method,
recovery period, and convention applica-
ble to the general asset account. The new
partnership is not bound by the terminated
partnership’s election under paragraph (l)
of this section.
(vii)Anti-abuse rule—(A)In general.
If an asset in a general asset account is
disposed of by a taxpayer in a transaction
described in paragraph (e)(3)(vii)(B) of
this section, general asset account treat-
ment for the asset terminates as of the
first day of the taxable year in which the
disposition occurs. Consequently, the
taxpayer must determine the amount of
gain, loss, or other deduction attribut-
able to the disposition in the manner de-
scribed in paragraph (e)(3)(iii)(A) of this
section (notwithstanding that paragraph
(e)(3)(iii)(A) of this section is an optional
rule) and must make the adjustments to the
general asset account described in para-
graphs (e)(3)(iii)(C)(1) through (4)ofthis
section.
(B)Abusive transactions. A trans-
action is described in this paragraph
(e)(3)(vii)(B) if the transaction is not de-
scribed in paragraph (e)(3)(iv), (e)(3)(v),
or (e)(3)(vi) of this section, and if the
transaction is entered into, or made, with
a principal purpose of achieving a tax
benefit or result that would not be avail-
able absent an election under this section.
Examples of these types of transactions
include—
(1) A transaction entered into with a
principal purpose of shifting income or de-
ductions among taxpayers in a manner that
would not be possible absent an election
under this section to take advantage of dif-
fering effective tax rates among the tax-
payers; or
(2) An election madeunder this section
with a principal purpose of disposing of an
asset from a general asset account to uti-
lize an expiring net operating loss or credit
if the transaction is not abona fidedispo-
sition. The fact that a taxpayer with a net
operating loss carryover or a credit carry-
over transfers an asset to a related person
or transfers an asset pursuant to an arrange-
ment where the asset continues to be used
(or is available for use) by the taxpayer
pursuant to a lease (or otherwise) indicates,
absent strong evidenceto the contrary, that
the transaction is described in this para-
graph (e)(3)(vii)(B).
(f)Assets generating foreign source
income—(1)In general. This paragraph
(f) provides the rules for determining the
source of any income, gain, or loss recog-
nized, and the appropriate section 904(d)
separate limitation category or categories
for any foreign source income, gain, or
loss recognized on a disposition (within
the meaning of paragraph (e)(1) of this
section) of an asset in a general asset ac-
count that consists of assets generating
both United States and foreign source
income. These rules apply only to a dispo-
sition to which paragraphs (e)(2) (general
disposition rules), (e)(3)(ii) (disposition
of all assets remaining in a general asset
account), (e)(3)(iii) (disposition of an as-
set in a qualifying disposition), (e)(3)(v)
(transactions subject to section 1031 or
section 1033), or (e)(3)(vii) (anti-abuse
rule) of this section applies. Solely for
purposes of applying this paragraph (f),
the termassetis:
(i) The asset as determined under para-
graph (e)(2)(viii) of this section, or
(ii) The portion of such asset that is dis-
posed of in a disposition described in para-
graph (e)(1)(ii) of this section.
(2)Source of ordinary income, gain,
or loss—(i)Source determined by alloca-
tion and apportionment of depreciation al-
lowed. The amount of any ordinary in-
come, gain, or loss that is recognized on
the disposition of an asset in a general as-
set account must be apportioned between
United States and foreign sources based on
the allocation and apportionment of the—
(A) Depreciation allowed for the gen-
eral asset account as of the end of the tax-
able year in which the disposition occurs
if paragraph (e)(2) of this section applies
to the disposition;
(B) Depreciation allowed for the gen-
eral asset account as of the time of dis-
position if the taxpayer applies paragraph
(e)(3)(ii) of this section to the disposition
of all assets, the last asset, or the remain-
ing portion of the last asset, in the general
asset account, or if all the assets, the last
asset, or the remaining portion of the last
asset, in the general asset account are dis-
posed of in a transaction described in para-
graph (e)(3)(v)(A) of this section; or
(C) Depreciation allowed for the asset
disposed of for only the taxable year in
which the disposition occurs if the tax-
payer applies paragraph (e)(3)(iii) of this
section to the disposition of the asset in a
qualifying disposition, if the asset is dis-
posed of in a transaction described in para-
graph (e)(3)(v)(B) of this section (like-
kind exchange or involuntary conversion),
or if the asset is disposed of in a transac-
tion described in paragraph (e)(3)(vii) of
this section (anti-abuse rule).
(ii)Formula for determining foreign
source income, gain, or loss. The amount
of ordinary income, gain, or loss rec-
ognized on the disposition that shall be
treated as foreign source income, gain, or
loss must be determined under the formula
in this paragraph (f)(2)(ii). For purposes
of this formula, the allowed depreciation
deductions are determined for the appli-
cable time period provided in paragraph
(f)(2)(i) of this section. The formula is:
2013–43 I.R.B.417October 21, 2013

Foreign Source Income, Gain, or Loss
from the Disposition of an Asset
= Total Ordinary Income, Gain, or Loss
from the Disposition of an Asset
X Allowed Depreciation Deductions
Allocated and Apportioned to
Foreign Source Income/Total Allowed
Depreciation Deductions for the
General Asset Account or for the Asset
Disposed of (as applicable)
(3)Section 904(d) separate categories.
If the assets in the general asset account
generate foreign source income in more
than one separate category under section
904(d)(1) or another section of the Inter-
nal Revenue Code (for example, income
treated as foreign source income under
section 904(g)(10)), or under a United
States income tax treaty that requires the
foreign tax credit limitation to be deter-
mined separately for specified types of
income, the amount of “foreign source
income, gain, or loss from the disposition
of an asset” (as determined under the for-
mula in paragraph (f)(2)(ii) of this section)
must be allocated and apportioned to the
applicable separate category or categories
under the formula in this paragraph (f)(3).
For purposes of this formula, the allowed
depreciation deductions are determined
for the applicable time period provided
in paragraph (f)(2)(i) of this section. The
formula is:
Foreign Source Income, Gain, or Loss
in a Separate Category
= Foreign Source Income, Gain, or Loss
from The Disposition of an Asset
X Allowed Depreciation Deductions
Allocated and Apportioned to a
Separate Category Total/Allowed
Depreciation Deductions and
Apportioned to Foreign Source Income
(g)Assets subject to recapture.Ifthe
basis of an asset in a general asset ac-
count is increased as a result of the recap-
ture of any allowable credit or deduction
(for example, the basis adjustment for the
recapture amount under section 30(d)(2),
50(c)(2), 168(l)(7), 168(n)(4), 179(d)(10),
179A(e)(4), or 1400N(d)(5)), general as-
set account treatment for the asset termi-
nates as of the first day of the taxable year
in which the recapture event occurs. Con-
sequently, the taxpayer must remove the
asset from the general asset account as of
that day and must make the adjustments
to the general asset account described in
paragraphs (e)(3)(iii)(C)(2) through (4)of
this section.
(h)Changes in use—(1)Conversion to
any personal use. An asset in a general
asset account becomes ineligible for gen-
eral asset account treatment if a taxpayer
uses the asset in any personal activity dur-
ing a taxable year. Upon a conversion to
any personal use, the taxpayer must re-
move the asset from the general asset ac-
count as of the first day of the taxable year
in which the change in use occurs (the year
of change) and must make the adjustments
to the general asset account described in
paragraphs (e)(3)(iii)(C)(2) through (4)of
this section.
(2)Change in use results in a dif-
ferent recovery period or depreciation
method—(i)No effect on general asset
account election. A change in the use
described in §1.168(i)–4(d) (change in
use results in a different recovery period
or depreciation method) of an asset in a
general asset account shall not cause or
permit the revocation of the election made
under this section.
(ii)Asset is removed from the general
asset account. Upon a change in the use
described in §1.168(i)–4(d), the taxpayer
must remove the asset from the general as-
set account as of the first day of the year
of change (as defined in §1.168(i)–4(a))
and must make the adjustments to the gen-
eral asset account described in paragraphs
(e)(3)(iii)(C)(2) through (4) of this sec-
tion. If, however, the result of the change
in use is described in §1.168(i)–4(d)(3)
(change in use results in a shorter recovery
period or a more accelerated depreciation
method) and the taxpayer elects to treat the
asset as though the change in use had not
occurred pursuant to §1.168(i)–4(d)(3)(ii),
no adjustment is made to the general asset
account upon the change in use.
(iii)New general asset account is es-
tablished—(A)Change in use results in
a shorter recovery period or a more ac-
celerated depreciation method.Ifthere-
sult of the change in use is described in
§1.168(i)–4(d)(3) (change in use results
in a shorter recovery period or a more
accelerated depreciation method) and ad-
justments to the general asset account are
made pursuant to paragraph (h)(2)(ii) of
this section, the taxpayer must establish a
new general asset account for the asset in
the year of change in accordance with the
rules in paragraph (c) of this section, ex-
cept that the adjusted depreciable basis of
the asset as of the first day of the year of
change is included in the general asset ac-
count. For purposes of paragraph (c)(2)
of this section, the applicable depreciation
method, recovery period, and convention
are determined under §1.168(i)–4(d)(3)(i).
(B)Change in use results in a longer
recovery period or a slower depreciation
method. If the result of the change in use is
described in §1.168(i)–4(d)(4) (change in
use results in a longer recovery period or a
slower depreciation method), the taxpayer
must establish a separate general asset ac-
count for the asset in the year of change
in accordance with the rules in paragraph
(c) of this section, except that the unad-
justed depreciable basis of the asset, and
the greater of the depreciation of the asset
allowed or allowable in accordance with
section 1016(a)(2), as of the first day of the
year of change are included in the newly
established general asset account. Conse-
quently, this general asset account as of the
first day of the year of change will have a
beginning balance for both the unadjusted
depreciable basis and the depreciation re-
serve of the general asset account. For pur-
poses of paragraph (c)(2) of this section,
October 21, 20134182013–43 I.R.B.

the applicable depreciation method, recov-
ery period, and convention are determined
under §1.168(i)–4(d)(4)(ii).
(i)Redetermination of basis.If,af-
ter the placed-in-service year, the unad-
justed depreciable basis of an asset in a
general asset account is redetermined due
to a transaction other than that described
in paragraph (g) of this section (for exam-
ple, due to contingent purchase price or
discharge of indebtedness), the taxpayer’s
election under paragraph (l) of this section
for the asset also applies to the increase or
decrease in basis resulting from the rede-
termination. For the taxable year in which
the increase or decrease in basis occurs, the
taxpayer must establish a new general as-
set account for the amount of the increase
or decrease in basis in accordance with the
rules in paragraph (c) of this section. For
purposes of paragraph (c)(2) of this sec-
tion, the applicable recovery period for the
increase or decrease in basis is the recov-
ery period of the asset remaining as of the
beginning of the taxable year in which the
increase or decrease in basis occurs, the ap-
plicable depreciation method and applica-
ble convention for the increase or decrease
in basis are the same depreciation method
and convention applicable to the asset that
applies for the taxable year in which the
increase or decrease in basis occurs, and
the increase or decrease in basis is deemed
to be placed in service in the same taxable
year as the asset.
(j)Identification of disposed or con-
verted asset—(1)In general.Therules
of this paragraph (j) apply when an asset
in a general asset account is disposed of
or converted in a transaction described
in paragraphs (e)(3)(iii) (disposition of
an asset in a qualifying disposition),
(e)(3)(iv)(B) (transactions subject to sec-
tion 168(i)(7)), (e)(3)(v)(B) (transactions
subject to section 1031 or section 1033),
(e)(3)(vii) (anti-abuse rule), (g) (assets
subject to recapture), or (h)(1) (conversion
to any personal use) of this section.
(2)Identifying which asset is disposed
of or converted—(i)In general. For pur-
poses of identifying which asset in a gen-
eral asset account is disposed of or con-
verted, a taxpayer must identify the dis-
posed of or converted asset by using—
(A) The specific identification method
of accounting. Under this method of ac-
counting, the taxpayer can determine the
particular taxable year in which the dis-
posed of or converted asset was placed in
service by the taxpayer;
(B) A first-in, first-out method of ac-
counting if the taxpayer can readily deter-
mine from its records the total dispositions
of assets with the same recovery period
during the taxable year but the taxpayer
cannot readily determine from its records
the unadjusted depreciable basis of the dis-
posed of or converted asset. Under this
method of accounting, the taxpayer iden-
tifies the general asset account with the
earliest placed-in-service year that has the
same recovery period as the disposed of or
converted asset and that has assets at the
beginning of the taxable year of the dis-
position or conversion, and the taxpayer
treats the disposed of or converted asset as
being from that general asset account. To
determine which general asset account has
assets at the beginning of the taxable year
of the disposition or conversion, the tax-
payer reduces the number of assets origi-
nally included in the account by the num-
ber of assets disposed of or converted in
any prior taxable year in a transaction to
which this paragraph (j) applies;
(C) A modified first-in, first-out
method of accounting if the taxpayer can
readily determine from its records the to-
tal dispositions of assets with the same
recovery period during the taxable year
and the unadjusted depreciable basis of
the disposed of or converted asset. Under
this method of accounting, the taxpayer
identifies the general asset account with
the earliest placed-in-service year that has
the same recovery period as the disposed
of or converted asset and that has assets
at the beginning of the taxable year of
the disposition or conversion with the
same unadjusted depreciable basis as the
disposed of or converted asset, and the
taxpayer treats the disposed of or con-
verted asset as being from that general
asset account. To determine which general
asset account has assets at the beginning
of the taxable year of the disposition or
conversion, the taxpayer reduces the num-
ber of assets originally included in the
account by the number of assets disposed
of or converted in any prior taxable year
in a transaction to which this paragraph (j)
applies;
(D) A mortality dispersion table if the
asset is a mass asset accounted for in a sep-
arate general asset account in accordance
with paragraph (c)(2)(ii)(H) of this section
and if the taxpayer can readily determine
from its records the total dispositions of
assets with the same recovery period dur-
ing the taxable year. The mortality dis-
persion table must be based upon an ac-
ceptable sampling of the taxpayer’s actual
disposition and conversion experience for
mass assets or other acceptable statistical
or engineering techniques. To use a mor-
tality dispersion table, the taxpayer must
adopt recordkeeping practices consistent
with the taxpayer’s prior practices and con-
sonant with good accounting and engineer-
ing practices; or
(E) Any other method as the Secretary
may designate by publication in theFed-
eral Registeror in the Internal Revenue
Bulletin (see §601.601(d)(2) of this chap-
ter) on or after September 19, 2013. See
paragraph (j)(2)(iii) of this section regard-
ing the last-in, first-out method of account-
ing.
(ii)Disposition of a portion of an as-
set. If a taxpayer disposes of a portion
of an asset and paragraph (e)(1)(ii) of this
section applies to that disposition, the tax-
payer may identify the asset by using any
applicable method provided in paragraph
(j)(2)(i) of this section (after taking into ac-
count paragraph (j)(2)(iii) of this section).
(iii)Last-in, first-out method of ac-
counting. For purposes of paragraph (j)(2)
of this section, a last-in, first-out method
of accounting may not be used. Under a
last-in, first-out method of accounting, the
taxpayer identifies the general asset ac-
count with the most recent placed-in-ser-
vice year that has the same recovery period
as the disposed of or converted asset and
that has assets at the beginning of the tax-
able year of the disposition or conversion,
and the taxpayer treats the disposed of or
converted asset as being from that general
asset account.
(3)Basis of disposed of or converted as-
set. Solely for purposes of this paragraph
(j)(3), the termassetis the asset as deter-
mined under paragraph (e)(2)(viii) of this
section or the portion of such asset that is
disposed of in a disposition described in
paragraph (e)(1)(ii) of this section. After
identifying which asset in a general asset
account is disposed of or converted, the
taxpayer may use any reasonable method
that is consistently applied to all assets in
the same general asset account for pur-
poses of determining the unadjusted depre-
ciable basis of the disposed of or converted
2013–43 I.R.B.419October 21, 2013

asset in that general asset account. Exam-
ples of a reasonable method include, but
are not limited to, discounting the cost of
the replacement asset to its placed-in-ser-
vice year cost using the Consumer Price
Index, apro rataallocation of the unad-
justed depreciable basis of the general as-
set account based on the replacement cost
of the disposed asset and the replacement
cost of all of the assets in the general asset
account, and a study allocating the cost of
the asset to its individual components.
(k)Effect of adjustments on prior dis-
positions. The adjustments to a general
asset account under paragraphs (e)(3)(iii),
(e)(3)(iv), (e)(3)(v), (e)(3)(vii), (g), or (h)
of this section have no effect on the recog-
nition and character of prior dispositions
subject to paragraph (e)(2) of this section.
(l)Election—(1)Irrevocable election.
If a taxpayer makes an election under this
paragraph (l), the taxpayer consents to, and
agrees to apply, all of the provisions of
this section to the assets included in a gen-
eral asset account. Except as provided in
paragraphs (c)(1)(ii)(A), (e)(3), (g), or (h)
of this section or except as otherwise ex-
pressly provided by other guidance pub-
lished in the Internal Revenue Bulletin (see
§601.601(d)(2) of this chapter), an election
made under this section is irrevocable and
will be binding on the taxpayer for com-
puting taxable income for the taxable year
for which the election is made and for all
subsequent taxable years. An election un-
der this paragraph (l) is made separately
by each person owning an asset to which
this section applies (for example, by each
member of a consolidated group, at the
partnership level (and not by the partner
separately), or at the S corporation level
(and not by the shareholder separately)).

§1.168(i)–1T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2014.
(5)Change in method of accounting.
A change to comply with this section for
depreciable assets placed in service in a
taxable year ending on or after December
30, 2003, is a change in method of ac-
counting to which the provisions of sec-
tion 446(e) and the regulations under sec-
tion 446(e) apply. A taxpayer also may
treat a change to comply with this section
for depreciable assets placed in service in
a taxable year ending before December 30,
2003, as a change in method of accounting
to which the provisions of section 446(e)
and the regulations under section 446(e)
apply. This paragraph (m)(5) does not ap-
ply to a change to comply with paragraphs
(e)(3)(ii), (e)(3)(iii), or paragraph (l) of this
section.

gle asset account beginning in the taxable
year in which the disposition occurs. See
§1.168(i)–8(h)(3)(i).
*****
(e)Effective/applicability date—(1)In
general. This section applies to taxable
years beginning on or after January 1,
2014.
(2)Early application of this section.A
taxpayer may choose to apply the provi-
sions of this section to taxable years begin-
ning on or after January 1, 2012.

not rely on the provisions of this section
in regulation project REG–110732–13 for
taxable years beginning on or after Jan-
uary 1, 2014.
(4)Optional application of TD
9564. A taxpayer may choose to apply
§1.168(i)–7T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2012. However, a taxpayer may not apply
§1.168(i)–7T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2014.
(5)Change in method of accounting.A
change to comply with this section for de-
preciable assets placed in service in a tax-
able year ending on or after December 30,
2003, is a change in method of accounting
to which the provisions of section 446(e)
and the regulations under section 446(e)
apply. A taxpayer also may treat a change
to comply with this section for deprecia-
ble assets placed in service in a taxable
year ending before December 30, 2003, as
a change in method of accounting to which
the provisions of section 446(e) and the
regulations under section 446(e) apply.
Par. 5. Section 1.168(i)–8 is added to
read as follows:
§1.168(i)–8 Dispositions of MACRS
property.
(a)Scope. This section provides rules
applicable to dispositions of MACRS
property (as defined in §1.168(b)–1(a)(2))
or to depreciable property (as defined in
§1.168(b)–1(a)(1)) that would be MACRS
property but for an election made by the
taxpayer either to expense all or some
of the property’s cost under section 179,
179A, 179B, 179C, 179D, or 1400I(a)(1),
or any similar provision, or to amortize all
October 21, 20134202013–43 I.R.B.

or some of the property’s cost under sec-
tion 1400I(a)(2) or any similar provision.
This section also applies to dispositions
described in paragraph (d)(1) of this sec-
tion of a portion of such property. Except
as provided in §1.168(i)–1(e)(iii), this
section does not apply to dispositions of
assets included in a general asset account.
For rules applicable to dispositions of as-
sets included in a general asset account,
see §1.168(i)–1(e) or §1.168(e)–1T, as
applicable.
(b)Definitions. For purposes of this
section—
(1)Buildinghas the same meaning as
that term is defined in §1.48–1(e)(1).
(2)Dispositionoccurs when ownership
of the asset is transferred or when the as-
set is permanently withdrawn from use ei-
ther in the taxpayer’s trade or business or
in the production of income. A dispo-
sition includes the sale, exchange, retire-
ment, physical abandonment, or destruc-
tion of an asset. A disposition also occurs
when an asset is transferred to a supplies,
scrap, or similar account, or when a portion
of an asset is disposed of as described in
paragraph (d)(1) of this section. If a struc-
tural component (or a portion thereof) of a
building is disposed of in a disposition de-
scribed in paragraph (d)(1) of this section,
a disposition also includes the disposition
of such structural component (or such por-
tion thereof).
(3)Mass assetsis a mass or group of
individual items of depreciable assets—
(i) That are not necessarily homoge-
nous;
(ii) Each of which is minor in value
relative to the total value of the mass or
group;
(iii) Numerous in quantity;
(iv) Usually accounted for only on a
total dollar or quantity basis;
(v) With respect to which separate iden-
tification is impracticable; and
(vi) Placed in service in the same tax-
able year.
(4)Portionofanassetis any part of
an asset that is less than the entire asset as
determined under paragraph (c)(4) of this
section.
(5)Structural componenthas the
same meaning as that term is defined in
§1.48–1(e)(2).
(6)Unadjusted depreciable basis of the
multiple asset account or poolis the sum
of the unadjusted depreciable bases (as de-
fined in §1.168(b)–1(a)(3)) of all assets
included in the multiple asset account or
pool.
(c)Special rules—(1)Manner of dis-
position. The manner of disposition (for
example, normal retirement, abnormal re-
tirement, ordinary retirement, or extraordi-
nary retirement) is not taken into account
in determining whether a disposition oc-
curs or gain or loss is recognized.
(2)Disposition by transfer to a supplies
account. If a taxpayer made an election
under §1.162–3(d) to treat the cost of
any rotable spare part, temporary spare
part, or standby emergency spare part
(as defined in §1.162–3(c)) as a capital
expenditure subject tothe allowance for
depreciation, the taxpayer can dispose of
the rotable, temporary, or standby emer-
gency spare part by transferring it to a
supplies account only if the taxpayer has
obtained the consent of the Commissioner
to revoke the §1.162–3(d) election. See
§1.162–3(d)(3) for the procedures for re-
voking a §1.162–3(d) election.
(3)Leasehold improvements. This sec-
tion also applies to—
(i) A lessor of leased property that made
an improvement to that property for the
lessee of the property, has a depreciable ba-
sis in the improvement, and disposes of the
improvement before or upon the termina-
tion of the lease with the lessee. See sec-
tion 168(i)(8)(B); and
(ii) A lessee of leased property that
made an improvement to that property, has
a depreciable basis in the improvement,
and disposes of the improvement before
or upon the termination of the lease.
(4)Determination of asset disposed
of—(i)General rules. For purposes of
applying this section, the facts and circum-
stances of each disposition are considered
in determining what is the appropriate
asset disposed of. The asset for dispo-
sition purposes may not consist of items
placed in service by the taxpayer on dif-
ferent dates. For purposes of determining
what is the appropriate asset disposed of,
the unit of property determination under
§1.263(a)–3(e) or in published guidance
in the Internal Revenue Bulletin (see
§601.601(d)(2) of this chapter) under sec-
tion 263(a) does not apply.
(ii)Special rules. In addition to the gen-
eral rules in paragraph(c)(4)(i) of this sec-
tion, the following rules apply for purposes
of applying this section:
(A) Each building (including its struc-
tural components) is the asset except
as provided in §1.1250–1(a)(2)(ii) or
in paragraph (c)(4)(ii)(B) or paragraph
(c)(4)(ii)(D) of this section.
(B) If a building has two or more con-
dominium or cooperative units, each con-
dominium or cooperative unit (including
its structural components) is the asset ex-
cept as provided in §1.1250–1(a)(2)(ii) or
in paragraph (c)(4)(ii)(D) of this section.
(C) If a taxpayer properly includes
an item in one of the asset classes 00.11
through 00.4 of Rev. Proc. 87–56 (1987–2
C.B. 674) (see §601.601(d)(2) of this
chapter) or properly classifies an item
in one of the categories under section
168(e)(3) (except for a category that in-
cludes buildings or structural components;
for example, retail motor fuels outlet,
qualified leasehold improvement property,
qualified restaurant property, and qualified
retail improvement property), each item is
the asset provided paragraph (c)(4)(ii)(D)
of this section does not apply to the item.
For example, each desk is the asset, each
computer is the asset, and each qualified
smart electric meter is the asset.
(D) If the taxpayer places in service an
improvement or addition to an asset after
the taxpayer placed the asset in service,
the improvement or addition is a separate
asset.
(d)Disposition of a portion of an as-
set—(1)In general. For purposes of ap-
plying this section, a disposition includes
a disposition of a portion of an asset as
a result of a casualty event described in
section 165, a disposition of a portion of
an asset for which gain (determined with-
out regard to section 1245 or section 1250)
is not recognized in whole or in part un-
der section 1031 or section 1033, a trans-
fer of a portion of an asset in a transac-
tion described in section 168(i)(7)(B), or
a sale of a portion of an asset, even if the
taxpayer does not make the election under
paragraph (d)(2)(i) of this section for that
disposed portion. For other transactions, a
disposition includes a disposition of a por-
tion of an asset only if the taxpayer makes
the election under paragraph (d)(2)(i) of
this section for that disposed portion.
(2)Partial disposition election—(i)In
general. A taxpayer may make an elec-
tion under this paragraph (d)(2) to apply
this section to a disposition of a portion of
an asset. If the asset isproperly included
2013–43 I.R.B.421October 21, 2013

in one of the asset classes 00.11 through
00.4 of Rev. Proc. 87–56 (1987–2 C.B.
674) (see §601.601(d)(2) of this chapter),
a taxpayer may make an election under this
paragraph (d)(2) to apply this section to a
disposition of a portion of such asset only
if the taxpayer classifies the replacement
portion of the asset under the same asset
class as the disposed portion of the asset.
(ii)Time and manner for making elec-
tion—(A)Time for making election.Ex-
cept as provided in paragraph (d)(2)(iii) or
paragraph (d)(2)(iv) of this section, a tax-
payer must make the election specified in
paragraph (d)(2)(i) of this section by the
due date (including extensions) of the orig-
inal Federal tax return for the taxable year
in which the portion of an asset is disposed
of by the taxpayer.
(B)Manner of making election.Ex-
cept as provided in paragraph (d)(2)(iii) or
paragraph (d)(2)(iv) of this section, a tax-
payer must make the election specified in
paragraph (d)(2)(i) of this section by ap-
plying the provisions of this section for the
taxable year in which the portion of an as-
set is disposed of by the taxpayer, by re-
porting the gain, loss, or other deduction
on the taxpayer’s timely filed (including
extensions) original Federal tax return for
that taxable year, and, if the asset is prop-
erly included in one of the asset classes
00.11 through 00.4 of Rev. Proc. 87–56
(1987–2 C.B. 674) (see §601.601(d)(2) of
this chapter), by classifying the replace-
ment portion of such asset under the same
asset class as the disposed portion of the
asset in the taxable year in which the re-
placement portion is placed in service by
the taxpayer. Except as provided in para-
graph (d)(2)(iii) or paragraph (d)(2)(iv)(B)
of this section, the election specified in
paragraph (d)(2)(i) of this section may not
be made through the filing of an applica-
tion for change in accounting method.
(iii)Special rule for subsequent In-
ternal Revenue Service adjustment.This
paragraph (d)(2)(iii) applies when a tax-
payer deducted the amount paid or in-
curred for the replacement of a portion
of an asset as a repair under §1.162–4,
the taxpayer did not make the election
specified in paragraph (d)(2)(i) of this
section for the disposed portion of that
asset within the time and in the manner
under paragraph (d)(2)(ii) or paragraph
(d)(2)(iv) of this section, and as a result of
an examination of the taxpayer’s Federal
tax return, the Internal Revenue Service
disallows the taxpayer’s repair deduction
for the amount paid or incurred for the
replacement of the portion of that asset
and instead capitalizes such amount under
§1.263(a)–2 or §1.263(a)–3. If this para-
graph (d)(2)(iii) applies, the taxpayer may
make the election specified in paragraph
(d)(2)(i) of this section for the disposition
of the portion of the asset to which the
Internal Revenue Service’s adjustment
pertains by filing an application for change
in accounting method, provided the asset
of which the disposed portion was a part is
owned by the taxpayer at the beginning of
the year of change (as defined for purposes
of section 446(e)).
(iv)Special rules for 2012 or 2013
returns. If, under paragraph (j)(2) or para-
graph (j)(3) of this section, a taxpayer
chooses to apply the provisions of this
section to a taxable year beginning on or
after January 1, 2012, and ending on or
before September 19, 2013 (applicable
taxable year), and the taxpayer did not
make the election specified in paragraph
(d)(2)(i) of this section on its timely filed
original Federal tax return for the applica-
ble taxable year, including extensions, the
taxpayer must make the election specified
in paragraph (d)(2)(i) of this section for the
applicable taxable year by filing either—
(A) An amended Federal tax return
for the applicable taxable year on or be-
fore 180 days from the due date including
extensions of the taxpayer’s Federal tax
return for the applicable taxable year,
notwithstanding that the taxpayer may not
have extended the due date; or
(B) An application for change in ac-
counting method with the taxpayer’s
timely filed original Federal tax return for
the first or second taxable year succeeding
the applicable taxable year.
(v)Revocation. A taxpayer may re-
voke the election specified in paragraph
(d)(2)(i) of this section only by filing a re-
quest for a private letter ruling and obtain-
ing the Commissioner’s consent to revoke
the election. The Commissioner may grant
a request to revoke this election if the tax-
payer acted reasonably and in good faith,
and the revocation will not prejudice the
interests of the Government. See generally
§301.9100–3 of this chapter. The election
specified in paragraph (d)(2)(i) of this sec-
tion may not be revoked through the filing
of an application forchange in accounting
method.
(e)Gain or loss on dispositions.Solely
for purposes of this paragraph (e), the term
assetis an asset within the scope of this
section or the portion of such asset that is
disposed of in a disposition described in
paragraph (d)(1) of this section. Except as
provided by section 280B and §1.280B–1,
the following rules apply when an asset is
disposed of during a taxable year:
(1) If an asset is disposed of by sale, ex-
change, or involuntary conversion, gain or
loss must be recognized under the appli-
cable provisions of the Internal Revenue
Code.
(2) If an asset is disposed of by physi-
cal abandonment, lossmust be recognized
in the amount of the adjusted deprecia-
ble basis (as defined in §1.168(b)–1(a)(4))
of the asset at the time of the abandon-
ment (taking into account the applicable
convention). However, if the abandoned
asset is subject to nonrecourse indebted-
ness, paragraph (e)(1) of this section ap-
plies to the asset (instead of this paragraph
(e)(2)). For a loss from physical abandon-
ment to qualify for recognition under this
paragraph (e)(2), the taxpayer must intend
to discard the asset irrevocably so that the
taxpayer will neither use the asset again
nor retrieve it for sale, exchange, or other
disposition.
(3) If an asset is disposed of other than
by sale, exchange, involuntary conversion,
physical abandonment, or conversion to
personal use (as, for example, when the as-
set is transferred to a supplies or scrap ac-
count), gain is not recognized. Loss must
be recognized in the amount of the ex-
cess of the adjusted depreciable basis of
the asset at the time of the disposition (tak-
ing into account the applicable conven-
tion) over the asset’s fair market value at
the time of the disposition (taking into ac-
count the applicable convention).
(f)Basis of asset disposed of—(1)In
general. The adjusted basis of an asset dis-
posed of for computing gain or loss is its
adjusted depreciable basis at the time of
the asset’s disposition (as determined un-
der the applicable convention for the as-
set).
(2)Assets disposed of are in multiple
asset accounts. If the taxpayer accounts
for the asset disposed of in a multiple as-
set account or pool and it is impractica-
ble from the taxpayer’s records to deter-
October 21, 20134222013–43 I.R.B.

mine the unadjusted depreciable basis (as
defined in §1.168(b)–1(a)(3)) of the asset
disposed of, the taxpayer may use any rea-
sonable method that is consistently applied
to all assets in the same multiple asset ac-
count or pool for purposes of determin-
ing the unadjusted depreciable basis of as-
sets disposed of. Examples of a reasonable
method include, but are not limited to, dis-
counting the cost of the replacement asset
to its placed-in-service year cost using the
Consumer Price Index, apro rataalloca-
tion of the unadjusted depreciable basis of
the multiple asset account or pool based on
the replacement cost of the disposed asset
and the replacement cost of all of the assets
in the multiple asset account or pool, and a
study allocating the cost of the asset to its
individual components. To determine the
adjusted depreciable basis of an asset dis-
posed of in a multiple asset account, the
depreciation allowed or allowable for the
asset disposed of is computed by using the
depreciation method, recovery period, and
convention applicable to the multiple asset
account or pool in which the asset disposed
of was included and by including the ad-
ditional first year depreciation deduction
claimed for the asset disposed of.
(3)Disposition of a portion of an asset.
This paragraph (f)(3) applies only when a
taxpayer disposes of a portion of an asset
and paragraph (d)(1)of this section applies
to that disposition. For computing gain
or loss, the adjusted basis of the disposed
portion of the asset is the adjusted depre-
ciable basis of that disposed portion at the
time of its disposition (as determined un-
der the applicable convention for the as-
set). The taxpayer may use any reason-
able method for purposes of determining
the unadjusted depreciable basis (as de-
fined in §1.168(b)–1(a)(3)) of the disposed
portion of the asset. If a taxpayer disposes
of more than one portion of the same asset
and paragraph (d)(1)of this section applies
to more than one of those dispositions, the
taxpayer may use any reasonable method
that is consistently applied to all portions
of the same asset for purposes of deter-
mining the unadjusted depreciable basis of
each disposed portion of the asset. Exam-
ples of a reasonable method include, but
are not limited to, discounting the cost of
the replacement portion of the asset to its
placed-in-service year cost using the Con-
sumer Price Index, apro rataallocation of
the unadjusted depreciable basis of the as-
set based on the replacement cost of the
disposed portion of the asset and the re-
placement cost of the asset, and a study al-
locating the cost of the asset to its individ-
ual components. To determine the adjusted
depreciable basis of the disposed portion
of the asset, the depreciation allowed or al-
lowable for the disposed portion is com-
puted by using the depreciation method,
recovery period, and convention applica-
ble to the asset in which the disposed por-
tion was included and by including the por-
tion of the additional first year deprecia-
tion deduction claimed for the asset that is
attributable to the disposed portion.
(g)Identification of asset disposed
of—(1)In general. Except as provided
in paragraph (g)(2) or paragraph (g)(3) of
this section, a taxpayer must use the spe-
cific identification method of accounting
to identify which asset is disposed of by
the taxpayer. Under this method of ac-
counting, the taxpayer can determine the
particular taxable year in which the asset
disposed of was placed in service by the
taxpayer.
(2)Asset disposed of is in a multiple
asset account. If a taxpayer accounts for
the asset disposed of in a multiple asset
account or pool and the total dispositions
of assets with the same recovery period
during the taxable year are readily deter-
mined from the taxpayer’s records, but it is
impracticable from the taxpayer’s records
to determine the particular taxable year in
which the asset disposed of was placed in
service by the taxpayer, the taxpayer must
identify the asset disposed of by using—
(i) A first-in, first-out method of ac-
counting if the unadjusted depreciable
basis of the asset disposed of cannot be
readily determined from the taxpayer’s
records. Under this method of account-
ing, the taxpayer identifies the multiple
asset account or pool with the earliest
placed-in-service year that has the same
recovery period as the asset disposed of
and that has assets at the beginning of the
taxable year of the disposition, and the
taxpayer treats the asset disposed of as
being from that multiple asset account or
pool;
(ii) A modified first-in, first-out method
of accounting if the unadjusted depreciable
basis of the asset disposed of can be readily
determined from the taxpayer’s records.
Under this method of accounting, the tax-
payer identifies the multiple asset account
or pool with the earliest placed-in-service
year that has the same recovery period as
the asset disposed of and that has assets at
the beginning of the taxable year of the dis-
position with the same unadjusted depre-
ciable basis as the asset disposed of, and
the taxpayer treats the asset disposed of as
being from that multiple asset account or
pool;
(iii) A mortality dispersion table if the
asset disposed of is a mass asset. The
mortality dispersion table must be based
upon an acceptable sampling of the tax-
payer’s actual disposition experience for
mass assets or other acceptable statistical
or engineering techniques. To use a mor-
tality dispersion table, the taxpayer must
adopt recordkeeping practices consistent
with the taxpayer’s prior practices and con-
sonant with good accounting and engineer-
ing practices; or
(iv) Any other method as the Secretary
may designate by publication in theFed-
eral Registeror in the Internal Revenue
Bulletin (see §601.601(d)(2) of this chap-
ter) on or after September 19, 2013. See
paragraph (g)(4) of this section regarding
the last-in, first-out method of accounting.
(3)Disposition of a portion of an asset.
If a taxpayer disposes of a portion of an as-
set and paragraph (d)(1) of this section ap-
plies to that disposition, but it is impracti-
cable from the taxpayer’s records to deter-
mine the particular taxable year in which
the asset was placed in service, the tax-
payer must identify the asset by using any
applicable method provided in paragraph
(g)(2) of this section (after taking into ac-
count paragraph (g)(4) of this section).
(4)Last-in, first-out method of account-
ing. For purposes of paragraph (g)(2) of
this section, a last-in,first-out method of
accounting may not be used. Under a last-
in, first-out methodof accounting, the tax-
payer identifies the multiple asset account
or pool with the most recent placed-in-ser-
vice year that has the same recovery period
as the asset disposed of and that has assets
at the beginning of the taxable year of the
disposition, and the taxpayer treats the as-
set disposed of as being from that multiple
asset account or pool.
(h)Accounting for asset disposed
of—(1)Depreciation ends. Depreciation
ends for an asset at the time of the asset’s
disposition (as determined under the ap-
plicable convention for the asset). See
§1.167(a)–10(b). If the asset disposed
2013–43 I.R.B.423October 21, 2013

of is in a single asset account initially
or as a result of §1.168(i)–8(h)(2)(i) or
§1.168(i)–8(h)(3)(i), the single asset ac-
count terminates at the time of the asset’s
disposition (as determined under the ap-
plicable convention for the asset). If a
taxpayer disposes of a portion of an asset
and paragraph (d)(1)of this section applies
to that disposition, depreciation ends for
that disposed portion of the asset at the
time of the disposition of the disposed por-
tion (as determined under the applicable
convention for the asset).
(2)Asset disposed of in a multiple asset
account or pool. If the taxpayer accounts
for the asset disposed of in a multiple asset
account or pool, then—
(i) As of the first day of the taxable year
in which the disposition occurs, the asset
disposed of is removed from the multiple
asset account or pool and is placed into a
single asset account. See §1.168(i)–7(b) or
§1.168(i)–7T(b), as applicable;
(ii) The unadjusted depreciable basis of
the multiple asset account or pool must be
reduced by the unadjusted depreciable ba-
sis of the asset disposed of as of the first
day of the taxable year in which the dispo-
sition occurs. See paragraph (f)(2) of this
section for determining the unadjusted de-
preciable basis of the asset disposed of;
(iii) The depreciation reserve of the
multiple asset accountor pool must be
reduced by the depreciation allowed or
allowable for the asset disposed of as of
the end of the taxable year immediately
preceding the year of disposition, com-
puted by using the depreciation method,
recovery period, and convention applica-
ble to the multiple asset account or pool in
which the asset disposed of was included
and by including the additional first year
depreciation deduction claimed for the
asset disposed of; and
(iv) In determining the adjusted depre-
ciable basis of the asset disposed of at the
time of disposition (taking into account
the applicable convention), the deprecia-
tion allowed or allowable for the asset dis-
posed of is computed by using the depre-
ciation method, recovery period, and con-
vention applicable to the multiple asset ac-
count or pool in which the asset disposed
of was included and by including the ad-
ditional first year depreciation deduction
claimed for the asset disposed of.
(3)Disposition of a portion of an asset.
This paragraph (h)(3) applies only when a
taxpayer disposes of a portion of an asset
and paragraph (d)(1) ofthis section applies
to that disposition. In this case—
(i) As of the first day of the taxable year
in which the disposition occurs, the dis-
posed portion is placed into a single asset
account. See §1.168(i)–7(b);
(ii) The unadjusted depreciable basis of
the asset must be reduced by the unad-
justed depreciable basis of the disposed
portion of the first day of the taxable year
in which the disposition occurs. See para-
graph (f)(3) of this section for determining
the unadjusted depreciable basis of the dis-
posed portion;
(iii) The depreciation reserve of the as-
set must be reduced by the depreciation al-
lowed or allowable for the disposed por-
tion as of the end of the taxable year im-
mediately preceding the year of disposi-
tion, computed by using the depreciation
method, recovery period, and convention
applicable to theasset in which the dis-
posed portion was included and by includ-
ing the portion of the additional first year
depreciation deduction claimed for the as-
set that is attributable to the disposed por-
tion; and
(iv) In determining the adjusted depre-
ciable basis of the disposed portion at the
time of disposition (taking into account the
applicable convention), the depreciation
allowed or allowable for the disposed por-
tion is computed by using the depreciation
method, recovery period, and convention
applicable to theasset in which the dis-
posed portion was included and by includ-
ing the portion of the additional first year
depreciation deduction claimed for the as-
set that is attributable to the disposed por-
tion.
(i)Examples. The application of this
section is illustratedby the following ex-
amples. For purposes of these examples,
assume that section 168 as in effect on
September 19, 2013, applies to taxable
years beginning on or after January 1,
2014.
Example 1. A owns an office building with four
elevators. A replaces one of the elevators. The ele-
vator is a structural component of the office building.
In accordance with paragraph (c)(4)(ii)(A) of this sec-
tion, the office building (including its structural com-
ponents) is the asset for disposition purposes. A does
not make the partial disposition election provided un-
der paragraph (d)(2) of this section for the elevator.
Thus, the retirement of the replaced elevator is not
a disposition. As a result, depreciation continues for
the cost of the building (including the cost of the re-
tired elevator and the building’s other structural com-
ponents), and A does not recognize a loss for this re-
tired elevator. If A must capitalize the amount paid
for the replacement elevator pursuant to §1.263(a)–3,
the replacement elevator is a separate asset for dispo-
sition purposes pursuant to paragraph (c)(4)(ii)(D) of
this section and for depreciation purposes pursuant to
section 168(i)(6).
Example 2. The facts are the same as inExam-
ple 1
, except A accounts for each structural compo-
nent of the office building as a separate asset in its
fixed asset system. Although A treats each structural
component as a separate asset in its records, the of-
fice building (including its structural components) is
the asset for disposition purposes in accordance with
paragraph (c)(4)(ii)(A) of this section. Accordingly,
the result is the same as in
Example 1.
Example 3. The facts are the same as inExample
1
, except A makes the partial disposition election
provided under paragraph (d)(2) of this section for
the elevator. Although the office building (including
its structural components) is the asset for disposi-
tion purposes, the result of A making the partial
disposition election for the elevator is that the re-
tirement of the replaced elevator is a disposition.
Thus, depreciation for the retired elevator ceases
at the time of its retirement (taking into account
the applicable convention), and A recognizes a loss
upon this retirement. Further, A must capitalize the
amount paid for the replacement elevator pursuant
to §1.263(a)–3(k)(1)(i), and the replacement elevator
is a separate asset for disposition purposes pursuant
to paragraph (c)(4)(ii)(D) of this section and for
depreciation purposes pursuant to section 168(i)(6).
Example 4. B, a calendar-year commercial air-
line company, owns several aircraft that are used in
the commercial carrying of passengers and described
in asset class 45.0 of Rev. Proc. 87–56. B replaces
the existing engines on one of the aircraft with new
engines. Assume each aircraft is a unit of property as
determined under §1.263(a)–3(e)(3) and each engine
of an aircraft is a major component or substantial
structural part of the aircraft as determined under
§1.263(a)–3(k)(6). Assume also that B treats each
aircraft as the asset for disposition purposes in ac-
cordance with paragraph (c)(4) of this section. B
makes the partial disposition election provided under
paragraph (d)(2) of this section for the engines in
the aircraft. Although the aircraft is the asset for
disposition purposes, the result of B making the
partial disposition election for the engines is that the
retirement of the replaced engines is a disposition.
Thus, depreciation for the retired engines ceases
at the time of their retirement (taking into account
the applicable convention), and B recognizes a loss
upon this retirement. Further, B must capitalize the
amount paid for the replacement engines pursuant
to §1.263(a)–3(k)(1)(i), and the replacement engines
are a separate asset for disposition purposes pursuant
to paragraph (c)(4)(ii)(D) of this section and for
depreciation purposes pursuant to section 168(i)(6).
Example 5. The facts are the same as inExample
4
, except B does not make the partial disposition elec-
tion provided under paragraph (d)(2) of this section
for the engines. Thus, the retirement of the replaced
engines on one of the aircraft is not a disposition. As
a result, depreciation continues for the cost of the air-
craft (including the cost ofthe retired engines), and B
does not recognize a loss for these retired engines. If
B must capitalize the amount paid for the replacement
October 21, 20134242013–43 I.R.B.

engines pursuant to §1.263(a)–3, the replacement en-
gines are a separate asset for disposition purposes pur-
suant to paragraph (c)(4)(ii)(D) of this section and for
depreciation purposes pursuant to section 168(i)(6).
Example 6. C, a corporation, owns several trucks
that are used in its trade or business and described
in asset class 00.241 of Rev. Proc. 87–56. C re-
places the engine on one of the trucks with a new
engine. Assume each truck is a unit of property as
determined under §1.263(a)–3(e)(3) and each engine
is a major component or substantial structural part of
the truck as determined under §1.263(a)–3(k)(6). Be-
cause the trucks are described in asset class 00.241 of
Rev. Proc. 87–56, C must treat each truck as the asset
for disposition purposes. C does not make the partial
disposition election provided under paragraph (d)(2)
of this section for the engine. Thus, the retirement of
the replaced engine on the truck is not a disposition.
As a result, depreciation continues for the cost of the
truck (including the cost of the retired engine), and C
does not recognize a loss for this retired engine. If C
must capitalize the amount paid for the replacement
engine pursuant to §1.263(a)–3, the replacement en-
gine is a separate asset for disposition purposes pur-
suant to paragraph (c)(4)(ii)(D) of this section and for
depreciation purposes pursuant to section 168(i)(6).
Example 7. D owns a retail building. D replaces
60 percent of the roof of this building. In accordance
with paragraph (c)(4)(ii)(A) of this section, the retail
building (including its structural components) is the
asset for disposition purposes. Assume D must cap-
italize the costs incurred for replacing 60 percent of
the roof pursuant to §1.263(a)–3(k)(1)(vi). D makes
the partial disposition election provided under para-
graph (d)(2) of this section for the 60 percent of the
replaced roof. Thus, the retirement of 60 percent of
the roof is a disposition. As a result, depreciation for
60 percent of the roof ceases at the time of its retire-
ment (taking into account the applicable convention),
and D recognizes a loss upon this retirement. Further,
D must capitalize the amount paid for the 60 percent
of the roof pursuant to §1.263(a)–3(k)(1)(i) and (vi)
and the replacement 60 percent of the roof is a sep-
arate asset for disposition purposes pursuant to para-
graph (c)(4)(ii)(D) of this section and for depreciation
purposes pursuant to section 168(i)(6).
Example 8. (i) The facts are the same as inEx-
ample 7
. Ten years after replacing 60 percent of the
roof, D replaces 55 percent of the roof of the build-
ing. In accordance with paragraph (c)(4)(ii)(A) and
(D) of this section, for disposition purposes, the re-
tail building (including its structural components ex-
cept the replacement 60 percent of the roof) is an as-
set and the replacement 60 percent of the roof is a
separate asset. Assume D must capitalize the costs
incurred for replacing 55 percent of the roof pursuant
to §1.263(a)–3(k)(1)(vi). D makes the partial dispo-
sition election provided under paragraph (d)(2) of this
section for the 55 percent of the replaced roof. Thus,
the retirement of 55 percent of the roof is a disposi-
tion.
(ii) However, D cannot determine from its records
whether the replaced 55 percent is part of the 60 per-
cent of the roof replaced ten years ago or whether the
replaced 55 percent is part of the remaining 40 per-
cent of the original roof. Pursuant to paragraph (g)(3)
of this section, D identifies which asset it disposed of
by using the first-in, first-out method of accounting.
As a result, D disposed of the remaining 40 percent
of the original roof and 25 percent of the 60 percent
of the roof replaced ten years ago.
(iii) Thus, depreciation for the remaining 40 per-
cent of the original roof ceases at the time of its retire-
ment (taking into account theapplicable convention),
and D recognizes a loss upon this retirement. Further,
depreciation for 25 percent of the 60 percent of the
roof replaced ten years ago ceases at the time of its re-
tirement (taking into account the applicable conven-
tion), and D recognizes a loss upon this retirement.
Also, D must capitalize the amount paid for the 55
percent of the roof pursuant to §1.263(a)–3(k)(1)(i)
and (vi), and the replacement 55 percent of the roof
is a separate asset for disposition purposes pursuant
to paragraph (c)(4)(ii)(D) of this section and for de-
preciation purposes pursuant to section 168(i)(6).
Example 9. (i) On July 1, 2011, E, a calen-
dar-year taxpayer, purchased and placed in service
a multi-story office building that costs $20,000,000.
The cost of each structural component of the build-
ing was not separately stated. E accounts for the
building in its records as a single asset with a
cost of $20,000,000. E depreciates the building as
nonresidential real property and uses the optional
depreciation table that corresponds with the gen-
eral depreciation system, the straight-line method, a
39-year recovery period, and the mid-month conven-
tion. As of January 1, 2014, the depreciation reserve
for the building is $1,261,000.
(ii) On June 30, 2014, E replaces one of the of-
fice building’s elevators. E did not dispose of any
other structural components of this building in 2014.
E makes the partial disposition election provided un-
der paragraph (d)(2) of this section for this eleva-
tor. Although the office building (including its struc-
tural components) is the asset for disposition pur-
poses, the result of E making the partial disposition
election for the elevator is that the retirement of the
replaced elevator is a disposition. Because E cannot
identify the cost of the structural components of the
office building from its records, E determines the cost
of any disposed structural component of this build-
ing by discounting the cost of the replacement struc-
tural component to its placed-in-service year cost us-
ing the Consumer Price Index. Using this reasonable
method, E determines the cost of the retired elevator
by discounting the cost of the replacement elevator
to its cost in 2011 (the placed-in-service year) using
the Consumer Price Index, resulting in $150,000 of
the $20,000,000 purchase price for the building to be
the cost of the retired elevator. Using the optional de-
preciation table that corresponds with the general de-
preciation system, the straight-line method, a 39-year
recovery period, and the mid-month convention, the
depreciation allowed or allowable for the retired ele-
vator as of December 31, 2013, is $9,457.50.
(iii) For E’s 2014 Federal tax return, the loss for
the retired elevator is determined as follows. The de-
preciation allowed or allowable for 2014 for the re-
tired elevator is $1,763 ((unadjusted depreciable basis
of $150,000 x depreciation rate of 2.564% for 2014)
x 5.5/12 months). Thus, the adjusted depreciable ba-
sis of the retired elevator is $138,779.50 (the adjusted
depreciable basis of $140,542.50 removed from the
building cost less the depreciation allowed or allow-
able of $1,763 for 2014). As a result, E recognizes a
loss of $138,779.50 for the retired elevator in 2014,
which is subject to section 1231.
(iv) For E’s 2014 Federal tax return, the de-
preciation allowance for the building is computed
as follows. As of January 1, 2014, the unad-
justed depreciable basis of the building is reduced
from $20,000,000 to $19,850,000 ($20,000,000
less the unadjusted depreciable basis of $150,000
for the retired elevator), and the depreciation re-
serve of the building is reduced from $1,261,000
to $1,251,542.50 ($1,261,000 less the depreciation
allowed or allowable of $9,457.50 for the retired
elevator as of December 31, 2013). Consequently,
the depreciation allowance for the building for 2014
is $508,954 ($19,850,000 x depreciation rate of
2.564% for 2014).
(v) E also must capitalize the amount
paid for the replacement elevator pursuant to
§1.263(a)–3(k)(1)(i). The replacement elevator is a
separate asset for tax disposition purposes pursuant
to paragraph (c)(4)(ii)(D) of this section and for
depreciation purposes pursuant to section 168(i)(6).
Example 10. (i) Since 2005, F, a calendar year
taxpayer, has accounted for items of MACRS prop-
erty that are mass assets in pools. Each pool includes
only the mass assets that have the same depreciation
method, recovery period, and convention, and are
placed in service by F in the same taxable year. None
of the pools are general asset accounts under section
168(i)(4) and the regulations under section 168(i)(4).
F identifies any dispositions of these mass assets by
specific identification.
(ii) During 2014, F sells 10 items of mass assets
with a 5-year recovery period each for $100. Under
the specific identification method, F identifies these
mass assets as being from the pool established by F
in 2012 for mass assets with a 5-year recovery period.
Assume F depreciates this pool using the optional de-
preciation table that corresponds with the general de-
preciation system, the 200-percent declining balance
method, a 5-year recovery period, and the half-year
convention. F elected not to deduct the additional
first year depreciation provided by section 168(k) for
5-year property placed in service during 2012. As of
January 1, 2014, this pool contains 100 similar items
of mass assets with a total cost of $25,000 and a to-
tal depreciation reserveof $13,000. Because all the
items of mass assets in the pool are similar, F allo-
cates the cost and depreciation allowed or allowable
for the pool ratably among each item in the pool. Us-
ing this reasonable method (because all the items of
mass assets in the pool are similar), F allocates a cost
of $250 ($25,000 x (1/100)) to each disposed of mass
asset and depreciation allowed or allowable of $130
($13,000 x (1/100)) to each disposed of mass asset.
The depreciation allowed or allowable in 2014 for
each disposed of mass asset is $24 (($250 x 19.2%)
/ 2). As a result, the adjusted depreciable basis of
each disposed of mass asset under section 1011 is $96
($250 - $130 - $24). Thus, F recognizes a gain of $4
for each disposed of mass asset in 2014, which is sub-
ject to section 1245.
(iii) Further, as of January 1, 2014, the unadjusted
depreciable basis of the 2012 pool of mass assets with
a 5-year recovery period is reduced from $25,000 to
$22,500 ($25,000 less the unadjusted depreciable ba-
sis of $2,500 for the 10 disposed of items), and the de-
preciation reserve of this 2012 pool is reduced from
$13,000 to $11,700 ($13,000 less the depreciation al-
lowed or allowable of $1,300 for the 10 disposed of
items as of December 31, 2013). Consequently, as
2013–43 I.R.B.425October 21, 2013

of January 1, 2014, the 2012 pool of mass assets
with a 5-year recovery period has 90 items with a
total cost of $22,500 and a depreciation reserve of
$11,700. Thus, the depreciation allowance for this
pool for 2014 is $4,320 ($22,500 x 19.2%).
Example 11. (i) The facts are the same as inEx-
ample 10
. Because of changes in F’s recordkeep-
ing in 2015, it is impracticable for F to continue to
identify disposed of mass assets using specific iden-
tification and to determine the unadjusted deprecia-
ble basis of the disposed of mass assets. As a re-
sult, F files a Form 3115, Application for Change in
Accounting Method, to change to a first-in, first-out
method beginning with the taxable year beginning on
January 1, 2015, on a modified cut-off basis. See
§1.446–1(e)(2)(ii)(
d)(2)(vii). Under the first-in, first-
out method, the mass assets disposed of in a taxable
year are deemed to be from the pool with the earliest
placed-in-service year that has assets as of the begin-
ning of the taxable year of the disposition with the
same recovery period as the asset disposed of. The
Commissioner of Internal Revenue consents to this
change in method of accounting.
(ii) During 2015, F sells 20 items of mass assets
with a 5-year recovery period each for $50. As of
January 1, 2015, the 2008 pool is the pool with the
earliest placed-in-service year for mass assets with
a 5-year recovery period, and this pool contains 25
items of mass assets with a total cost of $10,000 and
a total depreciation reserve of $10,000. Thus, F allo-
cates a cost of $400 ($10,000 x (1/25)) to each dis-
posed of mass asset and depreciation allowed or al-
lowable of $400 to each disposed of mass asset. As
a result, the adjusted depreciable basis of each dis-
posed of mass asset is $0. Thus, F recognizes a gain
of $50 for each disposed of mass asset in 2015, which
is subject to section 1245.
(iii) Further, as of January 1, 2015, the unadjusted
depreciable basis of the 2008 pool of mass assets with
a 5-year recovery period is reduced from $10,000 to
$2,000 ($10,000 less the unadjusted depreciable ba-
sis of $8,000 for the 20 disposed of items ($400 x
20)), and the depreciation reserve of this 2008 pool is
reduced from $10,000 to $2,000 ($10,000 less the de-
preciation allowed or allowable of $8,000 for the 20
disposed of items as of December 31, 2014). Conse-
quently, as of January 1, 2015, the 2008 pool of mass
assets with a 5-year recovery period has 5 items with
a total cost of $2,000 and a depreciation reserve of
$2,000.
(j)Effective/applicability date—(1)In
general. This section applies to taxable
years beginning on or after January 1,
2014.
(2)Early application of this section.A
taxpayer may choose to apply the provi-
sions of this section to taxable years begin-
ning on or after January 1, 2012.
(3)Early application of regulation
project REG–110732–13. A taxpayer may
rely on the provisions of this section in
regulation project REG–110732–13 for
taxable years beginning on or after Jan-
uary 1, 2012. However, a taxpayer may
not rely on the provisions of this section
in regulation project REG–110732–13 for
taxable years beginning on or after Jan-
uary 1, 2014.
(4)Optional application of TD
9564. A taxpayer may choose to apply
§1.168(i)–8T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2012. However, a taxpayer may not apply
§1.168(i)–8T as contained in TD 9564 (76
FR 81060) December 27, 2011, to taxable
years beginning on or after January 1,
2014.
(5)Change in method of accounting.
A change to comply with this section for
depreciable assets placed in service in a
taxable year ending on or after December
30, 2003, is a change in method of ac-
counting to which the provisions of sec-
tion 446(e) and the regulations under sec-
tion 446(e) apply. A taxpayer also may
treat a change to comply with this section
for depreciable assets placed in service in
a taxable year ending before December 30,
2003, as a change in method of accounting
to which the provisions of section 446(e)
and the regulations under section 446(e)
apply. This paragraph (j)(5) does not ap-
ply to a change to comply with paragraph
(d)(2) of this section (except as provided
in paragraph (d)(2)(iii) or (d)(2)(iv)(B) of
this section).

Definition of Terms
Revenue rulings and revenue procedures
(hereinafter referred to as “rulings”) that
have an effect on previous rulings use the
following defined terms to describe the ef-
fect:
Amplifieddescribes a situation where
no change is being made in a prior pub-
lished position, but the prior position is be-
ingextendedtoapplytoavariationofthe
fact situation set forth therein. Thus, if
an earlier ruling held that a principle ap-
plied to A, and the new ruling holds that the
same principle also applies to B, the earlier
ruling is amplified. (Compare withmodi-
fied,below).
Clarifiedis used in those instances
where the language in a prior ruling is be-
ing made clear because the language has
caused, or may cause, some confusion.
It is not used where a position in a prior
ruling is being changed.
Distinguisheddescribes a situation
where a ruling mentions a previously pub-
lished ruling and points out an essential
difference between them.
Modifiedis used where the substance
of a previously published position is being
changed. Thus, if a prior ruling held that a
principle applied to A but not to B, and the
new ruling holds that it applies to both A
and B, the prior ruling is modified because
it corrects a published position. (Compare
withamplifiedandclarified, above).
Obsoleteddescribes a previously pub-
lished ruling that is not considered deter-
minative with respect to future transac-
tions. This term is most commonly used in
a ruling that lists previously published rul-
ings that are obsoleted because of changes
in laws or regulations. A ruling may also
be obsoleted because the substance has
been included in regulations subsequently
adopted.
Revokeddescribes situations where the
position in the previously published ruling
is not correct and the correct position is
beingstatedinanewruling.
Supersededdescribes a situation where
the new ruling does nothing more than re-
state the substance and situation of a previ-
ously published ruling (or rulings). Thus,
the term is used to republish under the
1986 Code and regulations the same po-
sition published under the 1939 Code and
regulations. The term is also used when
it is desired to republish in a single rul-
ing a series of situations, names, etc., that
were previously published over a period of
time in separate rulings. If the new rul-
ing does more than restate the substance
of a prior ruling, a combination of terms
is used. For example,modifiedandsu-
persededdescribes a situation where the
substance of a previously published ruling
is being changed in part and is continued
without change in part and it is desired to
restate the valid portion of the previously
published ruling in a new ruling that is self
contained. In this case,the previously pub-
lished ruling is first modified and then, as
modified, is superseded.
Supplementedis used in situations in
which a list, such as a list of the names of
countries, is published in a ruling and that
list is expanded by adding further names in
subsequent rulings. After the original rul-
ing has been supplemented several times, a
new ruling may be published that includes
the list in the original ruling and the ad-
ditions, and supersedes all prior rulings in
the series.
Suspendedis used in rare situations to
show that the previous published rulings
will not be applied pending some future
action such as the issuance of new or
amended regulations, the outcome of cases
in litigation, or the outcome of a Service
study.
