in a restricted country (Cuba) for purposes of the limitation set
forth in section 911(d)(8)(A) of the Code and thus, an individ-
ual working at Guantanamo Bay is eligible for the section 911
foreign earned income exclusion, provided that the other re-
quirements of that section are met.

This notice announces that the IRS and Treasury intend to issue
regulations under section 367(b) to address certain triangular
reorganizations involving foreign corporations. The regulations
will apply to triangular reorganizations where either the parent
corporation or its subsidiary are foreign and where the sub-
sidiary acquires from the parent, in exchange for property, par-
ent stock that is used to acquire the stock or assets of a target
corporation. The regulations will treat the transfer of property
from the subsidiary to its parent as a distribution of property
under section 301(c) and make corresponding adjustments.

applies, the tie-breaking rule in section 152(c)(4) applies to
the head of household filing status, the child and dependent
care credit, the child tax credit, the earned income credit, the
exclusion for dependent care assistance, and the dependency
deduction as a group, rather than on a section-by-section basis.

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 and may be obtained from the
Superintendent of Documents on a subscription basis. Bulletin
contents are compiled semiannually into Cumulative Bulletins,
which are sold on a single-copy basis.
It is the policy of the Service to publish in the Bulletin all sub-
stantive rulings necessary to promote a uniform application of
the tax laws, including all rulings that supersede, revoke, mod-
ify, or amend any of those previously published in the Bulletin.
All published rulings apply retroactively unless otherwise indi-
cated. Procedures relating solely to matters of internal man-
agement are 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.—19
86 Code.
This part i
ncludes rulings and decisions based on provisions of
the Intern
al 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 Sec-
retary (Enforcement).
Part IV
.—Items of General Interest.
This par
t includes notices of proposed rulemakings, disbar-
ment an
d 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.
The c
ontents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

term, and long-term rates are set forth for the month
of October 2006. See Rev. Rul. 2006-50, page 672.
Low-income housing credit; satisfac-

ers who dispose of qualified low-income
buildings or interests therein during the pe-
riod January through December 2006.
Rev. Rul. 2006–51
In Rev. Rul. 90–60, 1990–2 C.B.
3, the Internal Revenue Service provided
guidance to taxpayers concerning the gen-
eral methodology used by the Treasury
Department in computing the bond factor
amounts used in calculating the amount of
bond considered satisfactory by the Secre-
tary under § 42(j)(6) of the Internal Rev-
enue Code. It further announced that the
Secretary would publishintheInternal
Revenue Bulletin a table of bond factor
amounts for dispositions occurring during
each calendar month.
Rev. Proc. 99–11, 1999–1 C.B. 275,
established a collateral program as an al-
ternative to providing a surety bond for
taxpayers to avoid or defer recapture of
the low-income housing tax credits under
§ 42(j)(6). Under this program, taxpayers
may establish a Treasury Direct Account
and pledge certain United States Treasury
securities to the Internal Revenue Service
as security.
This revenue ruling provides in Table
1 the bond factor amounts for calculat-
ing the amount of bond considered satis-
factory under § 42(j)(6) or the amount of
United States Treasury securities to pledge
in a Treasury Direct Account under Rev.
Proc. 99–11 for dispositions of qualified
low-income buildings or interests therein
during the period January through Decem-
ber 2006.

SUPPLEMENTARY INFORMATION:
Background
This document contains amendments to
26 CFR part 1. On September 8, 2003, the
IRS and Treasury Department published
temporary regulations (T.D. 9091, 2003–2
C.B. 939) in theFederal Register(68 FR
52986) relating to the additional first year
depreciation deduction provisions of sec-
tions 168(k) and 1400L(b) of the Internal
Revenue Code (Code). On the same date,
the IRS published a notice of proposed
rulemaking (REG–157164–02, 2003–2
October 10, 20066332006–41 I.R.B.

C.B. 1004) cross-referencing the tempo-
rary regulations in theFederal Register
(68 FR 53008). On March 1, 2004, the
temporary regulations (T.D. 9091) were
amended by the temporary regulations
(T.D. 9115, 2004–1 C.B. 680) published
by the IRS and Treasury Department in the
Federal Register(69 FR 9529) relating
to the depreciation of property acquired in
a like-kind exchange or as a result of an
involuntary conversion, and the notice of
proposed rulemaking (REG–157164–02)
was amended by the notice of proposed
rulemaking (REG–106590–00, 2004–1
C.B. 704, REG–138499–02, 2003–2 C.B.
541) published by the IRS in theFed-
eral Register(69 FR 9560) cross-ref-
erencing T.D. 9115. No public hearing
was requested or held. Several com-
ments responding to the notice of pro-
posed rulemaking (REG–157164–02)
were received. After consideration of all
the comments, the proposed regulations
(REG–157164–02) as amended by this
Treasury decision are adopted as final, and
the corresponding temporary regulations
(T.D. 9091) are removed. The revisions
are discussed below. Additionally, minor
changes are made to the temporary regula-
tions (T.D. 9115) to reflect the proper cites
of the final regulations.
Section 1400N(d), which was added
to the Code by section 101(a) of the Gulf
Opportunity Zone Act of 2005, Public
Law 109–135 (119 Stat. 2577), generally
allows a 50-percent additional first year
depreciation deduction (GO Zone addi-
tional first year depreciation deduction)
for qualified Gulf Opportunity Zone prop-
erty. Notice 2006–67, 2006–33 I.R.B.
248, provides guidance with respect to the
GO Zone additional first year deprecia-
tion deduction. Because Notice 2006–67
contains citations to the temporary regu-
lations under section 168(k) (T.D. 9091),
the IRS intends to update Notice 2006–67
to change these citations to this Treasury
decision.
Explanation of Provisions
Section 167 allows as a depreciation de-
duction a reasonable allowance for the ex-
haustion, wear, and tear of property used
in a trade or business or held for the pro-
duction of income. The depreciation al-
lowable for tangible, depreciable property
placed in service after 1986 generally is
determined under section 168 (MACRS
property). The depreciation allowable for
computer software that is placed in service
after August 10, 1993, and is not an amorti-
zable section 197 intangible is determined
under section 167(f)(1).
Section 168(k)(1) allows a 30-percent
additional first yeardepreciation deduc-
tion for qualified property acquired after
September 10, 2001, and, in most cases,
placed in service before January 1, 2005.
Section 168(k)(4) allows a 50-percent ad-
ditional first year depreciation deduction
for 50-percent bonus depreciation prop-
erty acquired after May 5, 2003, and, in
most cases, placed in service before Jan-
uary 1, 2005. Section 1400L(b) allows
a 30-percent additional first year depre-
ciation deduction for qualified New York
Liberty Zone property (Liberty Zone prop-
erty) acquired after September 10, 2001,
and placed in service before January 1,
2007 (January 1, 2010, in the case of qual-
ifying nonresidential real property and res-
idential rental property).
The final regulations provide the re-
quirements that must be met for deprecia-
ble property to qualify for the additional
first year depreciation deduction provided
by sections 168(k) and 1400L(b). Further,
the final regulations instruct taxpayers
how to determine the additional first year
depreciation deduction and the amount
of depreciation otherwise allowable for
eligible depreciable property. Unless
specifically stated, references to the tem-
porary regulations are to T.D. 9091.
Property Eligible for the Additional First
Year Depreciation Deduction
The final regulations retain the rules
contained in the temporary regulations
providing that depreciable property must
meet four requirements to be qualified
property under section 168(k)(2) (prop-
erty for which the 30-percent additional
first year depreciation deduction is al-
lowable) or 50-percent bonus depreciation
property under section 168(k)(4) (property
for which the 50-percent additional first
year depreciation deduction is allowable).
These requirements are: (1) the depre-
ciable property must be of a specified
type; (2) the original use of the depre-
ciable property mustcommence with the
taxpayer after September 10, 2001, for
qualifiedpropertyorafterMay5,2003,
for 50-percent bonus depreciation prop-
erty; (3) the depreciable property must be
acquired by the taxpayer within a speci-
fied time period; and (4) the depreciable
property must be placed in service by a
specified date.
Several commentators questioned
whether these requirements must be met in
the year in which the depreciable property
is placed in service by the taxpayer. The
statute is clear that additional first year
depreciation is allowed in the taxable year
in which qualified property or 50 percent
bonus depreciation property is placed in
service by the taxpayer for use in its trade
or business or for production of income.
Therefore, only property that meets all of
these requirements in the year in which
placed in service by the taxpayer for use
in its trade or business or for production
of income is allowed additional first year
depreciation in the year the property is
placed in service by the taxpayer for use
in its trade or business or for production
of income. In response to this comment,
the final regulations state more explicitly
that all of the requirements must be met in
the first taxable year in which the property
is subject to depreciation by the taxpayer
whether or not depreciation deductions are
allowable.
Property of a Specified Type
The final regulations retain the rules
contained in the temporary regulations
providing that qualified property or
50-percent bonus depreciation property
must be one of the following: (1) MACRS
property that has a recovery period of 20
years or less; (2) computer software as
defined in, and depreciated under, section
167(f)(1); (3) water utility property as de-
fined in section 168(e)(5) and depreciated
under section 168; or (4) qualified lease-
hold improvement property depreciated
under section 168.
The final regulations also retain the
rules contained in the temporary regula-
tions providing that qualified property or
50-percent bonus depreciation property
does not include: (1) property excluded
from the application of section 168 as a
result of section 168(f); (2) property that
is required to be depreciated under the
alternative depreciation system of section
168(g) (ADS); (3) any class of property
for which the taxpayer elects not to deduct
2006–41 I.R.B.634October 10, 2006

the 30-percent or 50-percent additional
first year depreciation; or (4) qualified
New York Liberty Zone leasehold im-
provement property as defined in section
1400L(c).
Property is required to be depreciated
under the ADS if the property is described
under section 168(g)(1)(A) through (D)
or if other provisions of the Code re-
quire depreciation for the property to
be determined under the ADS (for ex-
ample, section 263A(e)(2)(A) or section
280F(b)(1)). A commentator questioned
whether depreciable property held by tax-
payers that made the election under section
263A(d)(3) should be excluded from eli-
gibility for the additional first year depre-
ciation deduction. Section 263A(e)(2)(A)
provides that if a taxpayer (or a related
person) makes an election under section
263A(d)(3) (relating to an election not to
apply section 263A to any plant produced
in any farming business carried on by the
taxpayer), the ADS applies to all property
of the taxpayer used predominantly in the
farming business and placed in service in
any taxable year during which any such
election is in effect. Section 168(k) does
not exclude property for which the sec-
tion 263A(d)(3) election was made from
the application of section 168(k)(2)(D)(i),
which provides that property required
to be depreciated under the ADS is not
qualified property and 50-percent bonus
depreciation property. For this reason,
the final regulations do not adopt the sug-
gestion that depreciable property held by
taxpayers that made the election under
section 263A(d)(3) is eligible for the ad-
ditional first year depreciation deduction.
Another commentator requested clarifica-
tion as to whether the reference to “prop-
erty described in section 263A(e)(2)(A)”
in §1.168(k)–1T(b)(2)(ii)(A)(2) includes
only property held by a taxpayer that
has made an election under section
263A(d)(3). In response to this com-
ment, the final regulations clarify that
if the taxpayer (or a related person)
has made the election under section
263A(d)(3), the property described in
section 263A(e)(2)(A) is not eligible for
the additional first year depreciation de-
duction.
Original Use
The final regulations clarify and make
conforming changes to the original use
rules in the temporary regulations in sev-
eral respects. First, a commentator in-
quired whether the rule providing that the
cost of reconditioned or rebuilt property
acquired by the taxpayer does not satisfy
the original use requirement also applies
to self-constructed property. A few com-
mentators inquired whether the 20-percent
test for determining whether property is re-
conditioned or rebuiltapplies to self-con-
structed property. The IRS and Treasury
Department intended that these rules ap-
ply to the cost of any reconditioned or re-
built property, whether the taxpayer orig-
inally acquired the property or self-con-
structed the property. Accordingly, the fi-
nal regulations clarify that the cost of re-
conditioned or rebuilt property does not
satisfy the original use requirement and
that the 20-percent test applies to acquired
or self-constructed property.
Second,Example 2of §1.168(k)–
1T(b)(3)(v) provides that property held
primarily for sale to customers in the
ordinary course of a person’s business
(inventory) does not constitute a use for
purposes of the original use requirement.
A commentator noted that this rule is not
in the operative rules of the temporary
regulations. In response to this comment,
the final regulations make the rule explicit
and provide that if a person initially ac-
quires new property and holds the property
as inventory and a taxpayer subsequently
acquires the property from the person for
use primarily in the taxpayer’s trade or
business or primarily for the taxpayer’s
production of income, the taxpayer is con-
sidered the original user of the property.
The final regulations also provide that if
a taxpayer initially acquires new property
and holds the property as inventory and
then subsequently withdraws the property
from inventory and uses the property pri-
marily in the taxpayer’s trade or business
or primarily for the taxpayer’s production
of income, the taxpayer is considered the
original user of the property. In both sit-
uations, the final regulations provide that
the original use of the property by the tax-
payer commences on the date on which the
taxpayer uses the property primarily in the
taxpayer’s trade or business or primarily
for the taxpayer’s production of income.
A commentator questioned whetherEx-
ample 2in §1.168(k)– 1T(b)(3)(v) is the
appropriate place to resolve the issue of
the tax treatment of demonstrator auto-
mobiles for depreciation and other pur-
poses when the issue may have a poten-
tial broader scope and significance that
may continue to arise long after the addi-
tional first year depreciation under section
168(k) has ceased to be available. The IRS
and Treasury Department believe that this
example illustrates only the concept that if
property is held by a person as inventory
andthensoldtoataxpayerforuseinthe
taxpayer’s trade or business, the taxpayer
is the original user of the property, and,
therefore, that this example is in the appro-
priate place.
Third, the final regulations retain the
special rules contained in the temporary
regulations for certain sale-leaseback
transactions and syndication transactions.
A commentator suggested that the title
of §1.168(k)–1T(b)(3)(iii)(B), “Syndica-
tion transaction,” should be changed in
the final regulations to reflect that this
rule, by its terms, can apply to any sale
of property within three months after the
date on which it is placed in service, re-
gardless of whether that sale constitutes a
syndication. The final regulations adopt
this suggestion and modify the titles of,
and make conforming changes to, the ap-
plicable paragraphs. Similar changes also
are made to the paragraphs relating to the
placed-in-service date requirement.
Fourth, the final regulations modify
the provision in the temporary regula-
tions to implement section 403(a) of the
Working Families Tax Relief Act of 2004,
(Public Law 108–311, 118 Stat. 1166)
(October 4, 2004) (WFTRA) and section
337 of the American Jobs Creation Act
of 2004 (Public Law 108–357, 118 Stat.
1418) (October 22, 2004) (AJCA). Section
403(a) of the WFTRA amended section
168(k) by adding the provision in section
168(k)(2)(E)(iii). Section 403(f) of the
WFTRA provides that this amendment is
effective as if included in the provisions
of the Job Creation and Worker Assis-
tance Act of 2002 (Public Law 107–147,
116 Stat. 21) (March 9, 2002) (JCWAA).
Section 337(a) of the AJCA amended the
syndication transaction provision in sec-
tion 168(k)(2)(E)(iii)(II) by adding at the
end the following: “(or, in the case of mul-
tiple units of property subject to the same
October 10, 20066352006–41 I.R.B.

lease, within 3 months after the date the
final unit is placed in service, so long as
the period between the time the first unit
is placed in service and the time the last
unit is placed in service does not exceed
12 months).” Section 337(b) of the AJCA
provides that this amendment is effective
for property sold after June 4, 2004.
Fifth, if property placed in service by
a person is sold and leased back within
three months, and a syndication transac-
tion occurs within three months after the
sale-leaseback, a commentator questioned
whether the purchaser of the property
in the syndication transaction is consid-
ered the original user of the property
and whether the property is treated as
having been placed in service by the pur-
chaser in the syndication transaction. Pur-
suant to §§1.168(k)–1T(b)(3)(iii)(C) and
(5)(ii)(C), the purchaser of the property in
the syndication transaction is considered
the original user of the property and the
property is treatedas having been placed
in service by the purchaser in the syndi-
cation transaction. The final regulations
retain this rule and provide an example
illustrating both the original use and the
placed in service aspects of this situation.
Finally, the final regulations retain the
rule contained in the temporary regulations
providing that if, in the ordinary course
of its business, a taxpayer sells fractional
interests in qualified property or 50-per-
cent bonus depreciation property to un-
related third parties, each first fractional
owner of the property is considered as the
original user of its proportionate share of
the property. A commentator questioned
whether the rule requiring the sale to be to
unrelated third parties means that the pur-
chasers must be unrelated to the seller, the
purchasers must be unrelated to each other,
or both. The IRS and Treasury Department
intended that the purchasers be unrelated
to the seller. Accordingly, the final regula-
tions clarify this point.
A commentator questioned whether
there are circumstances when the
placed-in-service year of property is
before the taxable year of original use.
Pursuant to §1.46–3(d)(1)(ii), property is
considered placed in service in the tax-
able year in which the property is placed
in a condition or state of readiness and
availability for a specifically assigned
function, whether in a trade or business, in
the production of income, in a tax-exempt
activity, or in a personal activity. Original
use begins when new property is placed in
service. Consequently, the placed-in-ser-
vice year of new property cannot be before
the taxable year in which original use of
the property occurs.
Acquisition of Property
The final regulations modify the ac-
quisition dates in the temporary regula-
tions to reflect section 405 of the Gulf Op-
portunity Zone Act of 2005 (Public Law
109–135, 119 Stat. 2577) (December 21,
2005) (GOZA). Section 405(a)(1) of the
GOZA amended section 168(k)(4)(B)(ii)
to provide that 50-percent bonus depreci-
ation property is property (I) acquired by
the taxpayer after May 5, 2003, and be-
fore January 1, 2005, but only if no writ-
ten binding contract for the acquisition of
the property was in effect before May 6,
2003, or (II) acquired by the taxpayer pur-
suant to a written binding contract which
was entered into after May 5, 2003, and
before January 1, 2005. Section 405(b)
provides that this amendment is effective
as if included in section 201 of the Jobs
and Growth Tax Relief and Reconciliation
Act of 2003 (Public Law 108–27, 117 Stat.
752) (May 28, 2003).
Binding Contracts
The final regulations also modify in
three respects the rules contained in the
temporary regulations defining a binding
contract. First, the temporary regulations
provide that if a contract provides for a
full refund of the purchase price in lieu of
any damages allowable by law in the event
of breach or cancellation by the seller, the
contract is not considered binding. A com-
mentator suggested that this rule should
apply to a breach or cancellation by the
buyer, not the seller. However, the IRS
and Treasury Department believe that this
rule relates to a breach or cancellation by
either party. Accordingly, the final regu-
lations provide that if a contract provides
for a full refund of the purchase price in
lieu of any damages allowable by law in
the event of breach or cancellation, the
contract is not considered binding.
Second, with respect to a contract sub-
ject to a condition, the temporary regula-
tions provide that a contract that imposes
significant obligations on the taxpayer or
a predecessor will be treated as binding
notwithstanding the fact that insubstantial
termsremaintobenegotiatedbythepar-
ties to the contract. A commentator ques-
tioned whether this rule implies that a con-
tract that imposes significant obligations
will not be treated as binding if substan-
tial terms remain to be negotiated. The
IRS and Treasury Department believe that
this implication was not intended. As a
consequence, the finalregulations clarify
this rule by providing that a contract that
imposes significant obligations on the tax-
payer or a predecessor will be treated as
binding notwithstanding the fact that cer-
tain terms remain to be negotiated by the
parties to the contract.
Third, with respect to a supply agree-
ment, a commentator suggested that the
existence of agreed pricing terms should
not be relevant in determining whether or
not a supply agreement is a binding con-
tract, except to the extent that their absence
causes the contract not to be enforceable
under local law. The commentator further
suggested that if the existence of pricing
terms is considered relevant to the result
in the example of the operative rule and
in some of the examples that illustrate the
application of the rule, that requirement
should be stated in the operative rule, and
if not relevant, the references to pricing
terms should be deleted. Pricing terms are
not relevant in determining whether a sup-
ply agreement is a binding contract for pur-
poses of these regulations. Accordingly,
the final regulations adopt the suggestion
by eliminating the reference to agreed pric-
ing terms in the example of the operative
rule. While the examples that illustrate
the application of the rule continue to con-
tain the agreed price as a fact, the conclu-
sions in these examples depend upon only
whether or not the quantity and the de-
sign specification of the property to be pur-
chased are specified.
Self-constructed property
With respect to self-constructed prop-
erty, the final regulations clarify the rules
in the temporary regulations in several
respects. First, with respect to property
described in section 168(k)(2)(B) (longer
production period property) or section
168(k)(2)(C) (certain aircraft), the final
regulations clarify that if a taxpayer en-
ters into a written binding contract after
September 10, 2001, and before January 1,
2006–41 I.R.B.636October 10, 2006

2005, with another person to manufacture,
construct, or produce such property and
the manufacture, construction, or produc-
tion begins after December 31, 2004, the
taxpayer has acquired the property pur-
suant to a written binding contract entered
into after September 10, 2001, and before
January 1, 2005 (for qualified property) or
after May 5, 2003, and before January 1,
2005 (for 50-percent bonus depreciation
property).
Second, a commentator asked whether
the rules in the temporary regulations pro-
viding for when construction begins are in-
tended also to apply to manufacture and
production because self-constructed prop-
erty can be manufactured, constructed, or
produced for purposes of the additional
first year depreciation deduction. The IRS
and Treasury Department intended these
rules to apply to manufacture, construc-
tion, or production. Accordingly, the final
regulations make this clarification.
Third, the temporary regulations pro-
vide that construction of property begins
when physical work of a significant na-
ture begins and the determination of when
physical work of a significant nature
begins depends on the facts and circum-
stances. The temporary regulations also
provide that physical work of a significant
nature will not be considered to begin be-
fore the taxpayer incurs or pays more than
10 percent of the total cost of the property
(excluding the cost of any land and prelim-
inary activities). Several commentators
questioned whether this 10-percent test is
a safe harbor. The preamble to the tempo-
rary regulations (68 FR 52987) states that
the 10-percent test is a safe harbor. Conse-
quently, the final regulations are clarified
to provide that the 10-percent test is a safe
harbor. Further, when another party manu-
factures, constructs,or produces property
for the taxpayer, the final regulations clar-
ify that the safe harbor test must be met
by the taxpayer. Thus, under the final reg-
ulations, a taxpayer can determine when
manufacture, construction, or production
of the property begins either (1) by using
the 10 percent safe harbor or (2) by using
its own facts and circumstances.
Fourth, the final regulations retain the
rules contained in the temporary regula-
tions relating to components of self-con-
structed property. One of these rules is
that if the binding contract to acquire a
component is entered into, or the man-
ufacture, construction, or production of
a component begins, after September 10,
2001, for qualified property, or after May
5, 2003, for 50-percent bonus deprecia-
tion property, and before January 1, 2005,
but the manufacture, construction, or pro-
duction of the larger self-constructed prop-
erty begins after December 31, 2004, the
component qualifies for the additional first
year depreciation deduction (assuming all
other requirements are met) but the larger
self-constructed property does not. In the
case of a self-constructed component that
is to be incorporated into a larger self-
constructed property, some commentators
noted that the applicability of this rule is
limited. Specifically, one commentator
stated that if the 10 percent test mentioned
in the preceding paragraph is not a safe
harbor test, then the only case in which
self-constructed components could qualify
for the additional first year depreciation
deduction is one in which the taxpayer’s
pre-January 1, 2005, costs are 10 percent
or less of the total cost of the larger self-
constructed property (but more than 10
percent of the total cost of the component).
Another commentator stated that a self-
constructed component that is to be incor-
porated into a larger self-constructed prop-
erty may not be placed in service before
the larger self-constructed property. The
IRS and Treasury Department agree that
the rule has limited applicability. The rule
applies when the larger self-constructed
property is propertythat is manufactured,
constructed, or produced by the taxpayer
for its own use and that is described in sec-
tion 168(k)(2)(B) (longer production pe-
riod property) or section 168(k)(2)(C) (cer-
tain aircraft) and, therefore, the property is
eligible for the extended placed-in-service
date of January 1, 2006.
Disqualified transactions
The final regulations clarify the dis-
qualified transaction rules in the tempo-
rary regulations to reflect section 403(a) of
the WFTRA. This section amended section
168(k) by adding section 168(k)(2)(E)(iv),
which provides limitations related to users
and related parties (disqualified transac-
tions). Section 168(k)(2)(E)(iv) provides
that the termqualified propertydoes not
include any property if: (I) the user of
such property (as of the date on which the
property is originally placed in service) or
a person that is related (within the mean-
ing of section 267(b) or 707(b)) to such
user or to the taxpayer had a written bind-
ing contract in effect for the acquisition
of the property at any time on or before
September 10, 2001; or (II) in the case
of property manufactured, constructed, or
produced for such user’s or person’s own
use, the manufacture, construction, or pro-
duction of the property began at any time
on or before September 10, 2001. Section
403(f) of the WFTRA provides that this
amendment is effective as if included in the
provisions of the JCWAA.
Finally, the IRS and Treasury Depart-
ment decided to add new examples to illus-
trate the above rules. Further, inExample
10of §1.168(k)–1T(b)(4)(v), a commen-
tator inquired whether the taxpayer (S)
is considered to be self-constructing the
property, acquiring the property, or both.
The IRS and Treasury Department in-
tended to have the taxpayer both self-con-
structing and acquiring the property. The
final regulations make this clarification.
A commentator questioned whether
the result inExample 10of §1.168(k)–
1T(b)(4)(v) also would apply if before
September 11, 2001, a partnership began
construction of a power plant for its own
use, then after September 10, 2001, and
before completion of the plant, there is a
technical termination of the partnership
under section 708(b)(1)(B), and then sub-
sequently the new partnership incurred
additional expenditures to complete the
construction of the power plant and placed
the power plant in service before January
1, 2005. Assuming the terminated part-
nership and the new partnership are not
related parties, the new partnership is con-
sidered to have acquired the uncompleted
power plant and completed the construc-
tion of the power plant and, thus, the result
inExample 10of §1.168(k)–1T(b)(4)(v)
will apply to the new partnership in this
case. While the additional first year de-
preciation deduction for Liberty Zone
property requires the property to be ac-
quired by purchase, the same result would
apply because for purposes of that require-
ment, §1.1400L(b)–1T(c)(5)(ii) treats the
new partnership as acquiring the property
by purchase and the final regulations re-
tain this rule.
October 10, 20066372006–41 I.R.B.

Placed-in-service Date
The final regulations retain the rule con-
tained in the temporary regulations provid-
ing, pursuant to section 168(k)(2)(A)(iv)
and section 168(k)(4)(B)(iii), that quali-
fied property or 50-percent bonus depre-
ciation property is property that is placed
in service by the taxpayer before January
1, 2005. The temporary regulations also
provide that property described in section
168(k)(2)(B) (longer production period
property) must be placed in service before
January 1, 2006. The final regulations
modify this extended placed-in-service
date requirement in two respects. First, the
final regulations reflect that the extended
placed-in-service date of before January
1, 2006, also applies to property described
in section 168(k)(2)(C) (certain aircraft),
whichwasaddedtosection168(k)by
section 336 of the AJCA. Second, the fi-
nal regulations reflect that the extended
placed-in-service date of before January
1, 2006, is extended for one year to before
January 1, 2007, for property to which
Announcement 2006–29, 2006–19 I.R.B.
879 applies. Announcement 2006–29
applies to property described in section
168(k)(2)(B) or (C) that is either placed in
service by the taxpayer or manufactured
by a person in the Gulf Opportunity (GO)
Zone, the Rita GO Zone, or the Wilma
GO Zone, provided the taxpayer was
unable to meet the December 31, 2005,
placed-in-service date deadline for such
property as a result of Hurricane Katrina,
Hurricane Rita, or Hurricane Wilma.
Qualified Leasehold Improvement
Property
The final regulations retain the rules
contained in the temporary regulations re-
lating to qualified leasehold improvement
property. The temporary regulations pro-
vide that qualified leasehold improvement
property means any improvement, which
is section 1250 property, to an interior por-
tion of a building that is nonresidential real
property if, among other things, the im-
provement is made under or pursuant to a
lease by the lessee (or any sublessee) of the
interior portion, or by the lessor of that in-
terior portion. A commentator questioned
whether this rule means an improvement
that is permitted or required by a lease.
The IRS and Treasury Department believe
that the improvement must be made un-
der or pursuant to a lease, regardless of
whether the improvement is permitted or
required under the lease.
Computation of Additional First Year
Depreciation Deduction and Otherwise
Allowable Depreciation
The final regulations retain the rules
contained in the temporary regulations for
determining the amount of the additional
first year depreciation deduction and oth-
erwise allowable depreciation deduction.
In addition, the final regulations clarify
that the additional first year depreciation
deduction generally is allowable in the
first taxable year in which the qualified
property or 50-percent bonus depreciation
property is placed in service by the tax-
payer for use in its trade or business or for
the production of income.
Election Not to Claim Additional First
Year Depreciation Deduction
With respect to the election not to claim
the additional first year depreciation de-
duction, the final regulations retain the
rules contained in the temporary regu-
lations for making this election and for
defining what is a class of property for
purposes of the election. For any class
of property that is qualified property, a
taxpayer may elect out of the 30-per-
cent additional first year depreciation
deduction for any class of qualified prop-
erty. For any class of property that is
50-percent bonus depreciation property,
a taxpayer may elect either to deduct the
30-percent, instead ofthe 50-percent, ad-
ditional first year depreciation or to deduct
no additional first year depreciation. A
commentator asked whether a taxpayer
with 50-percent bonus depreciation prop-
erty must make two elections to elect not
to deduct any additional first year depre-
ciation. The final regulations clarify that
only one election is needed to elect not
to deduct both the 30-percent and 50-per-
cent additional first year depreciation for
50-percent bonus depreciation property.
If a taxpayer elects not to deduct any ad-
ditional first year depreciation for a class
of property, another commentator asked
whether the depreciation adjustments un-
der section 56 apply to property included
in such class for purposes of computing
the taxpayer’s alternative minimum tax-
able income. The non-applicability of the
depreciation adjustments under section 56
provided by section 168(k)(2)(G) applies
only to qualified property or 50-percent
bonus depreciation property. If a taxpayer
elects not to deduct any additional first
year depreciation for a class of property,
the property included in such class is not
qualified property or 50-percent bonus de-
preciation property.Accordingly, the fi-
nal regulations provide that if a taxpayer
elects not to deduct any additional first
year depreciation for a class of property,
the depreciation adjustments under section
56 apply to that property for purposes of
computing the taxpayer’s alternative min-
imum taxable income.
The final regulations also include the
procedures provided by section 3.04 of
Rev. Proc. 2002–33, 2002–1 C.B. 963, for
revokinganelectionnottodeductthead-
ditional first year depreciation for a class
of property. These procedures provide
that this election is revocable only with
the prior written consent of the Commis-
sioner of Internal Revenue and, to seek
the Commissioner’s consent, the taxpayer
must submit a request for a letter ruling.
However, the final regulations also pro-
vide an automatic 6-month extension from
the due date of the taxpayer’s Federal
tax return (excluding extensions) for the
placed-in-service year to revoke the elec-
tion, provided the taxpayer timely filed its
Federal tax return for the placed-in-service
year.
LibertyZoneProperty
Generally, the requirements for deter-
mining the eligibility of property for the
additional first year depreciation deduc-
tion for Liberty Zone property provided by
section 1400L(b) are similar to the require-
ments for the 30-percent additional first
year depreciation deduction for qualified
property provided by section 168(k)(1) in
the final regulations. The final regula-
tions made several changes to the tempo-
rary regulations with respect to the Liberty
Zone property, which are discussed below.
The final regulations retain the rule con-
tained in the temporary regulations provid-
ing that Liberty Zone property includes the
same property that is described as qualified
property or 50-percent bonus depreciation
property for purposes of section 168(k). In
2006–41 I.R.B.638October 10, 2006

addition, Liberty Zone property includes
nonresidential real property or residential
rental property to the extent such prop-
erty rehabilitates real property damaged,
or replaces real property destroyed or con-
demned, as a result of the terrorist attacks
of September 11, 2001. Real property is
considered to have been destroyed or con-
demned only if an entire building or struc-
ture was destroyed or condemned as a re-
sult of the terrorist attacks of September
11, 2001. Property is treated as replac-
ing destroyed or condemned property if, as
part of an integrated plan, the property re-
places real property that is included in a
continuous area thatincludes real property
destroyed or condemned. A commentator
noted that the temporary regulations sim-
ply reiterate the statute but do not define
the wordcontinuous. The IRS and Trea-
sury Department believe that the common
meaning ofcontinuousapplies.
The temporary regulations definereal
propertyas a building or its structural
components, or other tangible real prop-
erty except: (1) property described in
section 1245(a)(3)(B) (relating to depre-
ciable property used as an integral part
of a specified activity or as a specified
facility); (2) property described in sec-
tion 1245(a)(3)(D) (relating to a single
purpose agricultural or horticultural struc-
ture); and (3) property described in section
1245(a)(3)(E) (relating to storage facility
used in connection with the distribution
of petroleum or any primary product of
petroleum). A commentator suggested
that these exclusions to the definition of
real property should be deleted in the final
regulations. As a result of this definition,
nonresidential real property or residential
rental property that rehabilitates or re-
places any of the excluded properties that
were damaged, destroyed, or condemned,
is not eligible for the Liberty Zone addi-
tional first year depreciation deduction.
For this reason, the IRS and Treasury De-
partment agree. Accordingly, the final
regulations provide that real property is a
building or its structural components, or
other tangible real property.
The temporary regulations provide that
Liberty Zone property does not include
property that is described as qualified
property or 50-percent bonus depreci-
ation property for purposes of section
168(k), or property that is described in
§1.168(k)–1T(b)(2)(ii). The property de-
scribed in §1.168(k)–1T(b)(2)(ii) is prop-
erty that is: (1) described in section 168(f);
(2) required to be depreciated under the
alternative depreciation system; (3) in-
cluded in any class of property for which
the taxpayer elects out of the additional
first year depreciation deduction under
section 168(k); or (4) qualified Liberty
Zone leasehold improvement property.
Instead of providing a cross-reference to
§1.168(k)–1(b)(2)(ii), the final regula-
tions list the property that is described
in §1.168(k)–1(b)(2)(ii) with one modifi-
cation to the exclusion for property that
is included in any class of property for
which the taxpayer elects out of the ad-
ditional first year depreciation deduction
under section 168(k). In this regard, a
commentator stated that while section
1400L(b)(2)(C)(iv) provides that the elec-
tion out rules for purposes of section
1400L(b) are to be similar to the election
out rules under section 168(k), section
1400L(b)(2)(C)(iv) does not mean that the
same election must be made with respect
to both sections 168(k) and 1400L(b).
Accordingly, the commentator suggested
that a taxpayer be permitted to elect not
to apply section 168(k) to its property of
a particular class of property to the extent
that such property is not located within
the Liberty Zone, while still being entitled
to the benefits of section 1400L(b) for its
property of the same class that is located
within the Liberty Zone. The IRS and
Treasury Department agree with this sug-
gestion. Accordingly, the final regulations
make clear that Liberty Zone property
is not property included in any class of
property for which the taxpayer elects out
of the additional first year depreciation
deduction under section 1400L(b).
The final regulations retain the rule con-
tained in the temporary regulations provid-
ing that Liberty Zone property is property
that is acquired by the taxpayer by pur-
chase after September 10, 2001, but only
if no written binding contract for the ac-
quisition of the property was in effect be-
fore September 10, 2001. The termby
purchaseis defined in section 179(d) and
§1.179–4(c). The final regulations also re-
tain the rule contained in the temporary
regulations providing that the new partner-
ship resulting from a technical termination
under section 708(b)(1)(B) or a transferee
in section 168(i)(7) transactions is deemed
to acquire the depreciable property by pur-
chase. A commentator suggested that the
rule should apply only if the old transferor
partnership had itself acquired the prop-
erty by purchase, as the mere existence of
a technical termination does not provide
sufficient reason to deem the statutory pur-
chase requirement to have been met. The
final regulations do not adopt this sugges-
tion. Theruleistheresultoftherules
provided in the temporary regulations re-
garding the additional first year deprecia-
tion deduction under sections 168(k) and
1400L(b) that allow the new partnership
resulting from a technical termination to
be entitled to the additional first year de-
preciation deduction for eligible property
that was placed in service by the termi-
nated partnership during the taxable year
of termination. As a result, the IRS and
Treasury Department determined that the
rule should not be changed.
The final regulations also retain the
rules contained in the temporary regula-
tions for electing not to deduct the Liberty
Zone additional first year depreciation
deduction for a class of property. In addi-
tion, the final regulations for this election
include provisions similar to those previ-
ously discussed relating to the alternative
minimum tax and the revocation of the
election with respect to the election not to
deduct the additional first year deprecia-
tion deduction under section 168(k).
Special Rules
Similar to the temporary regulations,
the final regulations provide special rules
for the following situations: (1) qualified
property, 50-percent bonus depreciation
property, or Liberty Zone property placed
in service and disposed of in the same tax-
able year; (2) redetermination of basis of
qualified property, 50-percent bonus de-
preciation property, or Liberty Zone prop-
erty; (3) recapture of additional first year
depreciation for purposes of section 1245
and section 1250; (4) a certified pollution
control facility that is qualified property,
50-percent bonus depreciation property,
or Liberty Zone property; (5) like-kind
exchanges and involuntary conversions
of qualified property, 50-percent bonus
depreciation property, or Liberty Zone
property; (6) a change in use of qualified
property, 50-percent bonus depreciation
property, or Liberty Zone property; (7)
the computation of earnings and profits;
October 10, 20066392006–41 I.R.B.

(8) the increase in the limitation of the
amount of depreciation for passenger au-
tomobiles; and (9) the step-up in basis
due to a section 754 election. For some
of these situations, the final regulations
modify or clarify the rules contained in
the temporary regulations. In addition, the
final regulations provide rules for two new
situations: the rehabilitation credit under
section 47 and the computation of depre-
ciation for purposes of section 514(a)(3).
Property placed in service and disposed
of in the same taxable year
With respect to qualified property,
50-percent bonus depreciation property,
or Liberty Zone property placed in ser-
vice and disposed of in the same taxable
year, the final regulations retain the rules
contained in the temporary regulations. In
general, the regulations provide that the
additional first year depreciation deduc-
tion is not allowed. If qualified property
or 50-percent bonus depreciation property
is placed in service and disposed of by
a taxpayer in the same taxable year and
then, in a subsequent taxable year, is reac-
quired and again placed in service by the
taxpayer, a commentator inquired whether
the additional first year depreciation de-
duction is allowable in the subsequent
taxable year. Because the property is used
property in the subsequent taxable year,
the additional first year depreciation de-
duction is not allowable for the property
in the subsequent taxable year. Accord-
ingly, in this situation, the final regulations
clarify that the additional first year depre-
ciation deduction is not allowable for the
property in the subsequent taxable year.
The temporary regulations provide two
exceptions to the general rule. First, the
additional first year depreciation deduc-
tion is allowable for qualified property,
50-percent bonus depreciation property, or
Liberty Zone property placed in service by
a terminated partnership in the same tax-
able year in which a technical termination
of the partnership occurs. In this case, the
new partnership, and not the terminated
partnership, claims the additional first year
depreciation deduction. Second, the ad-
ditional first year depreciation deduction
is allowable for qualified property, 50-per-
cent bonus depreciation property, or Lib-
erty Zone property placed in service by
a transferor in the same taxable year in
which the property is transferred in a trans-
action described in section 168(i)(7). In
this case, the additional first year depre-
ciation deduction for the transferor’s tax-
able year in which the property is placed
in service is allocated between the trans-
feror and the transferee on a monthly basis.
The allocation shall be made in accordance
with the rules in §1.168(d)–1(b)(7)(ii) for
allocating the depreciation deduction be-
tween the transferor and the transferee.
Ifthetransfereehasadifferenttaxable
year than the transferor, a commentator
questioned whether the allocation of the
additional first yeardepreciation deduc-
tion would be made between the transferor
and the transferee in accordance with the
above rules. Becausethe allocation rules
in §1.168(d)–1(b)(7)(ii) cover this situa-
tion, the IRS and Treasury Department did
not modify the rule in the final regulations.
Redetermination of basis
The final regulations also retain the
rules contained in the temporary regula-
tions with respect to a redetermination
of basis of qualified property, 50-percent
bonus depreciation property, or Liberty
Zone property (for example, due to a con-
tingent purchase price or a discharge of
indebtedness). These rules apply to a rede-
termination of the unadjusted depreciable
basis of the property occurring before
January 1, 2005 (January 1, 2006, for the
extended placed-in-service date property)
for qualified property or 50-percent bonus
depreciation property, or before January 1,
2007 (January 1, 2010, in the case of non-
residential real property and residential
rental property) for Liberty Zone property.
A commentator suggested that the rules
should be expanded to include redeter-
minations of basis occurring on or after
these dates. The commentator pointed
out that the rule results in additional first
year depreciation not being allowable for
additional purchase price paid on or after
January 1, 2005, with respect to qualified
property or 50-percent bonus depreciation
property acquired before 2005. The final
regulations do not adopt this suggestion.
While the current rule may be unfavorable
when, for example, a redetermination of
basis results in an increase of basis on
or after January 1, 2005, for qualified
property or 50-percent bonus depreciation
property acquired before 2005, the current
rule may be favorable when, for exam-
ple, a redetermination of basis results in
a decrease of basis on or after January 1,
2005, with respect to qualified property
or 50-percent bonus depreciation property
acquired before 2005. Further, the IRS
and Treasury Department limited the rules
to redeterminations occurring before the
dates mentioned above to be consistent
with the dates on which property must
be placed in service to be eligible for the
additional first year depreciation deduc-
tion. For this reason, the IRS and Treasury
Department determined not to change the
rule in the final regulations.
In the case of a redetermination of
basis that results in a decrease in basis,
a commentator noted that the operative
rule provides that the taxpayer includes
in the taxpayer’s income the excess ad-
ditional first year depreciation deduction
previously claimed for the qualified prop-
erty, the 50-percent bonus depreciation
property, or the Liberty Zone property but
the example illustrating the application
of this rule allows the taxpayer to reduce
current year depreciation deductions by
the amount of the excess additional first
year depreciation deduction previously
claimed for the qualified property, the
50-percent bonus depreciation property,
or Liberty Zone property. Because the
IRS and Treasury Department recognize
that the lump-sum inclusion in income
approach provided in the operative rule of
the temporary regulation may adversely
affect real estate investment trusts and
similar entities, the final regulations pro-
vide that the excess additional first year
depreciation deduction offsets the amount
otherwise allowable for depreciation for
the taxable year. Even if the amount of
the offset exceeds the amount otherwise
allowable for depreciation for the taxable
year, the taxpayer takes into account a
negative depreciation deduction in com-
puting taxable income.
The final regulations retain the rule
contained in the temporary regulations
providing that, for purposes of the redeter-
mination of basis rules: (1) an increase in
basis occurs in the taxable year an amount
is taken into account under section 461;
and (2) a decrease in basis occurs in the
taxable year an amount is taken into ac-
count under section 451. A commentator
questioned whether because the event in
question is giving rise to a basis adjust-
2006–41 I.R.B.640October 10, 2006

ment, rather than to an item of income
or deduction, it is appropriate for the rule
to tie the timing of the adjustment to ac-
counting method rules concerning the
timing of income and deductions. The
commentator also noted that one apparent
effect of applying the accounting method
rules is to override the basis reduction
rule of section 1017(a) as illustrated in
Example 2of §1.168(k)–1T(f)(2)(iv). The
IRS and Treasury Department did not in-
tend to change the section 1017(a) rules.
While the IRS and Treasury Department
continue to believe that the current rule
is appropriate, the final regulations have
been modified for cases in which the Code,
the regulations under the Code, or other
published guidance expressly provides
an exception to such rule (for example,
section 1017(a)). Therefore,Example 2of
§1.168(k)–1(f)(2)(iv) in the final regula-
tions reflects the basis adjustment rules of
section 1017(a).
Like-kind exchanges and involuntary
conversions
With respect to MACRS property or
computer software acquired in a like-kind
exchange under section 1031 or as a re-
sult of an involuntary conversion under
section 1033, the final regulations change
the rules contained in the temporary reg-
ulations (T.D. 9091 as amended by T.D.
9115) in several respects. First, the final
regulations modify the scope of this provi-
sion to include property described in sec-
tion 168(k)(2)(C) (certain aircraft), which
was added to section 168(k) by section 336
of the AJCA, and to include property to
which Announcement 2006–29, 2006–19
I.R.B. 879, applies if the time of replace-
ment is after September 10, 2001, and be-
fore January 1, 2007. As previously noted,
Announcement 2006–29 applies to prop-
erty described in section 168(k)(2)(B) or
(C) that is either placed in service by the
taxpayer or manufactured by a person in
the Gulf Opportunity (GO) Zone, the Rita
GO Zone, or the Wilma GO Zone, pro-
vided the taxpayer was unable to meet the
December 31, 2005, placed-in-service date
deadline for such property as a result of
Hurricane Katrina, Hurricane Rita, or Hur-
ricane Wilma. Similar changes also are
made to the paragraph relating to the com-
putation of the additional first year depre-
ciation deduction for MACRS property or
computer software acquired in a like-kind
exchange or as a result of an involuntary
conversion.
A commentator inquired whether the
rules should be expanded to include ex-
changed or involuntarily converted prop-
erty that is subject to former section 168
(the accelerated costrecovery system or
ACRS) or that is pre–1981 depreciation
property. The current rules apply only
to exchanged or involuntarily converted
property that is MACRS property in or-
der to conform with §1.168(i)–6T (relat-
ing to depreciation of property acquired in
like-kind exchanges or as a result of in-
voluntary conversions). Accordingly, the
IRS and Treasury Department believe that
this issue is outside the scope of these reg-
ulations and should be addressed when the
temporary regulations under §1.168(i)–6T
are finalized.
Second, the temporary regulations de-
fine the time of replacement as the later
of when the acquired MACRS property
or acquired computer software is placed
in service, or the time of disposition of
the exchanged or involuntarily converted
property. A commentator expressed con-
cern that in the case of an involuntary
conversion under section 1033, the final
regulations may confer an unintended
benefit in the case of taxpayers who ac-
quired property prior to September 11,
2001, in order to replace property that was
ultimately requisitioned or condemned
after September 10, 2001, but as to which
the threat or imminence of condemna-
tion existed prior to that date. The IRS
and Treasury Department acknowledge
that the rule confers a benefit under such
circumstances, but continue to believe
that the rule is appropriate. Addition-
ally, the IRS and Treasury Department
decided to provide rules in the final reg-
ulations to address how the additional
first year depreciation deduction is treated
when §1.168(i)–6T(d)(4) applies. Section
1.168(i)–6T(d)(4) applies when, in an in-
voluntary conversion, a taxpayer acquires
and places in service acquired MACRS
property before the time of disposition
of the involuntarily converted MACRS
property. If the time of disposition of the
involuntarily converted MACRS prop-
erty is after December 31, 2004, or, in
the case of property described in section
168(k)(2)(B) or (C), after December 31,
2005 (or after December 31, 2006, in
the case of property described in section
168(k)(2)(B) or (C) to which Announce-
ment 2006–29 applies), the final regula-
tions provide that the time of replacement
is when the acquired MACRS property is
placed in service, provided the threat or
imminence of requisition or condemnation
of the converted property existed prior to
January 1, 2005, or, in the case of property
described in section 168(k)(2)(B) or (C),
existed before January 1, 2006 (or existed
before January 1, 2007, in the case of
property described in section 168(k)(2)(B)
or (C) to which Announcement 2006–29
applies). In this case,the final regulations
also modify the income inclusion rule
in §1.168(i)–6T(d)(4) to allow the addi-
tional first year depreciation deduction on
the remaining carryover basis of the ac-
quired MACRS property that is qualified
property, 50-percent bonus depreciation
property, or Liberty Zone property.
Third, the final regulations clarify the
rules contained in the temporary regula-
tions relating to the computation of the
additional first year depreciation deduc-
tion for property described in section
168(k)(2)(B) (longer production period
property) and for alternative minimum tax
purposes. In both cases, the temporary
regulations provide a cross-reference to
§1.168(k)–1T(d) (computation of depreci-
ation deduction for qualified property or
50-percent bonus depreciation property).
A commentator suggested that the purpose
of the reference to §1.168(k)–1T(d) should
be clarified. The final regulations adopt
this suggestion by deleting the cross-ref-
erence and providing rules for computing
the additional first year depreciation de-
duction for property described in section
168(k)(2)(B) (longer production period
property) and for alternative minimum tax
purposes.
Also, a commentator questioned
whether the rule that the additional first
year depreciation is calculated separately
with respect to the carryover basis and the
excess basis is appropriate, and suggested
that the rule should be simplified by elim-
inating the requirement of separate calcu-
lations. The IRS and Treasury Department
believe that the rule is appropriate because
it conforms with §1.168(i)–6T, which
requires separate calculations of deprecia-
tion for the carryover basis and the excess
basis.
October 10, 20066412006–41 I.R.B.

Fourth, the final regulations clarify
the rules contained in the temporary reg-
ulations relating to exchanged or invol-
untarily converted MACRS property or
exchanged or involuntarily converted
computer software that is placed in service
and disposed of in an exchange or involun-
tary conversion in the same taxable year.
In this case, the temporary regulations
provide that the additional first year de-
preciation deduction is not allowable for
the exchanged or involuntarily converted
MACRS property or the exchanged or in-
voluntarily converted computer software
if the MACRS property or computer soft-
ware is placed in service and disposed of
in an exchange or involuntary conversion
in the same taxable year. A commentator
suggested that the finalregulations clarify
that the reference in the above rule to the
MACRS property or computer software
that is placed in service and disposed of in
the same taxable year is the exchanged or
involuntarily converted MACRS property
or exchanged or involuntarily converted
computer software. The final regulations
adopt this suggestion.
Finally, a new example is added and
the facts in several of the examples are
clarified to reflect that the acquired prop-
erty must be new property in order to meet
the original use requirement and, there-
fore, qualify for the additional first year de-
preciation deduction.
Change in use
The final regulations retain the rules
contained in the temporary regulations
providing when the use of qualified prop-
erty, 50-percent bonus depreciation prop-
erty, or Liberty Zone property changes
in the hands of the same taxpayer during
the placed-in-service year or a subse-
quent taxable year. One of these rules
provide that if property is acquired by a
taxpayer for personal use and, during a
subsequent taxable year, is converted by
the taxpayer from personal use to business
or income-producing use, the additional
first year depreciation deduction is allow-
able for the propertyin the taxable year
the property is converted to business or
income-producing use (assuming all the
requirements for theadditional first year
depreciation deduction are met). Another
rule provides that if depreciable property
is not qualified property, 50-percent bonus
depreciation property, or Liberty Zone
property in the placed-in-service year, the
additional first yeardepreciation deduc-
tion is not allowable for the property even
if a change in the use of the property subse-
quent to the placed-in-service year results
in the property being qualified property,
50-percent bonus depreciation property,
or Liberty Zone property in the taxable
year of the change in use. A commentator
questioned whether these two rules are
inconsistent. The commentator further
noted that under §1.167(a)–11(e)(1)(i),
property that is ready for use in a per-
sonal activity is considered to be placed
in service. The IRS and Treasury De-
partment do not believe that the two rules
are inconsistent. Property is eligible for
the additional first year depreciation de-
ductionifinthefirstyearinwhichthe
property is subject todepreciation, the
property meets all the requirements to
qualify for the additional first year depre-
ciation deduction. Inthe case of property
that changes from personal use to a busi-
ness or income-producing use, the first
year such property is subject to deprecia-
tion is the year of conversion to business or
income-producing use. But in the case of
property that changes from a depreciable
use not eligible for the additional first year
depreciation deduction to a depreciable
use that is eligible for the additional first
year depreciation deduction, such property
did not meet the requirements to qualify
for the additional first year depreciation
deduction in the first year in which the
property is subjectto depreciation.
Earnings and profits
The final regulations retain the rule con-
tained in the temporary regulations pro-
viding that the additional first year de-
preciation deduction is not allowable for
purposes of computing earnings and prof-
its. A commentator suggested that because
this provision interprets section 312(k), the
regulations under section 312 should in-
clude a cross-reference to the regulations
under section 168(k). The IRS and Trea-
sury Department agree and, accordingly,
the final regulations adopt this suggestion.
280F(a)(1) limitation
The final regulations also retain the
rules contained in the temporary regula-
tions providing the increase in the lim-
itation under section 280F(a)(1) of the
amount of depreciation for certain passen-
ger automobiles that arequalified property
or 50-percent bonus depreciation property.
A commentator had three inquiries about
this increase in the limitation under section
280F(a)(1). First, the commentator asked
whether the increase in the limitation can
be taken as a section 179 expense. The
increase in the limitation under section
280F(a)(1) that is provided in the final
regulations may be taken as a section 179
expense. Second, the commentator asked
whether the increase in the limitation of
amount of depreciation for certain pas-
senger automobiles needs to be prorated
in a short taxable year. Because the ad-
ditional first year depreciation deduction
is not prorated for a short taxable year,
the increase in the limitation under section
280F(a)(1) that is provided in the final reg-
ulations also is not prorated. Third, when
calculating depreciation for an asset with
less than 100 percent business use, the
commentator asked whether the business
use percentage is applied to the increase
in the limitation of amount of depreciation
for certain passenger automobiles. If a
taxpayer’s business use of the automobile
is less than 100 percent, the business use
percentage is applied to the automobile’s
depreciation deduction, including the ad-
ditional first year depreciation deduction,
for the taxable year. The IRS and Treasury
Department believe that these issues are
outside the scope of these regulations and,
accordingly, the finalregulations do not
address these issues.
Section 754 election
Finally, the final regulations retain the
rules contained in the temporary regula-
tions relating to any increase in basis of
qualified property, 50-percent bonus de-
preciation property, or Liberty Zone prop-
erty due to a section 754 election. Under
these rules, such increase in basis gener-
ally is not eligible for the additional first
year depreciation deduction. However, if
qualified property, 50-percent bonus de-
preciation property, or Liberty Zone prop-
erty is placed in service by a partnership
in the taxable year the partnership termi-
nates under section 708(b)(1)(B), any in-
crease of basis of the qualified property,
50-percent bonus depreciation property, or
2006–41 I.R.B.642October 10, 2006

Liberty Zone property due to a section 754
election is eligible for the additional first
year depreciation deduction. A commen-
tator requested that we expand this termi-
nating partnership rule to any increase in
basis due to a section 754 election that
arises before or during the placed-in-ser-
vice year of the property. The IRS and
Treasury Department decided not to do so.
Theruleforaterminationofapartnership
under section 708(b)(1)(B) was made to be
consistent with the special rule allowing
the new partnership, instead of the termi-
nated partnership, to claim the additional
first year depreciation deduction for prop-
erty placed in service during the taxable
year of termination and contributed by the
terminated partnership to a new partner-
ship. The IRS and Treasury Department
believe that these rules should not be ex-
panded to cover any other situations.
A commentator also suggested that we
clarify the regulation to provide that any
increase in basis due to a section 754 elec-
tion that arises before or during the year in
which the qualified property, 50-percent
bonus depreciation property, or Liberty
Zone property is placed in service will
be taken into account for the additional
first year depreciation deduction. The IRS
and Treasury Department did not adopt
this suggestion in the final regulations.
The additional first year depreciation de-
duction rules provide for the accelerated
recovery of a taxpayer’s cost of qualified
property, 50-percent bonus depreciation
property, or Liberty Zone property. Many
basis increases resulting from a section
754 election bear no relation whatso-
ever to the cost of qualified property,
50-percent bonus depreciation property,
or Liberty Zone property. For example, if
a partnership with a section 754 election
in effect made a liquidating distribution
of high-basis property to a partner with
low basis in his partnership interest, the
basis of the partnership’s undistributed
property would be increased under section
734(b) by an amount equal to the decrease
in basis to the distributed property under
section 732(b). The amount of the section
734(b) basis increase allocable to qualified
property under section 755 would have no
correlation to the taxpayer’s cost of the
property. The IRS and Treasury Depart-
ment believe that the rules regarding any
basis increase due to a section 754 election
should remain limited to those provided in
the temporary regulations.
Rehabilitation credit
Several commentators asked whether
property that is qualified property, 50-per-
cent bonus depreciation property, or Lib-
erty Zone property qualifies for the reha-
bilitation credit under section 47. Section
47 allows a rehabilitation credit for quali-
fied rehabilitation expenditures for certain
buildings. Section 47(c)(2) defines the
termqualified rehabilitation expendi-
tureas meaning, in general, any amount
properly chargeable to capital account
for property for which depreciation is
allowable under section 168 and that is
nonresidential real property, residential
rental property, real property that has a
class life of more than 12.5 years, or an
addition or improvement thereof. How-
ever, a qualified rehabilitation expenditure
does not include any expenditure with re-
spect to which the taxpayer does not use
the straight line method over a recovery
period determined under section 168(c) or
(g). Because the additional first year de-
preciation deduction is not a straight line
method, the IRS and Treasury Department
have decided to provide in the final regu-
lations that if qualified rehabilitation ex-
penditures (as defined in section 47(c)(2)
and §1.48–12(c)) are qualified property,
50-percent bonus depreciation property, or
Liberty Zone property, the taxpayer may
claim the additional first year depreciation
deduction for the unadjusted depreciable
basis of the qualified rehabilitation expen-
ditures and may claim the rehabilitation
credit (provided the requirements of sec-
tion 47 are met) for the remaining basis of
the qualified rehabilitation expenditures
(unadjusted depreciable basis less the
additional first yeardepreciation deduc-
tion allowed or allowable, whichever is
greater) provided thetaxpayer depreciates
the remaining adjusted depreciable basis
of such expenditures using the straight line
method over a recovery period determined
under section 168(c) or (g). The taxpayer
may also claim the rehabilitation credit
for the portion of the basis of the qualified
rehabilitated building that is attributable
to the qualified rehabilitation expenditures
if the taxpayer elects not to deduct the
additional first year depreciation for the
class of property that includes the quali-
fied rehabilitated expenditures.
Depreciation under section 514(a)(3)
Finally, a few commentators questioned
whether a tax-exempt partner in a partner-
ship that has debt-financed property may
take advantage of the additional first year
depreciation deduction. In computing
under section 512 the unrelated business
taxable income for any taxable year, sec-
tion 514 provides the rules for determining
the amount of unrelated business taxable
income related to debt-financed property.
Under section 514(a)(3), the deductions al-
lowable with respect to each debt-financed
property is the sum of the deductions un-
der chapter 1 of the Code that are directly
connected with the debt-financed property
or the income therefrom, except that if
the debt-financed property is depreciable
property, the allowance must be computed
only by use of the straight-line method.
The final regulations provide that the ad-
ditional first year depreciation deduction
is not allowable for purposes of section
514(a)(3).
Changes in Method of Accounting
The IRS and Treasury Department in-
tend to issue administrative guidance pro-
viding procedures for automatic consent
for taxpayers that wish to seek a change in
method of accounting to comply with these
final regulations.
Effective Date
In general, the final regulations apply
to qualified property or Liberty Zone prop-
erty acquired by a taxpayer after Septem-
ber 10, 2001, and for 50-percent bonus
depreciation property acquired by a tax-
payer after May 5, 2003. Modifications to
§1.168(k)–1(b)(3)(iii)(B) and (5)(ii)(B) re-
lating to syndication and other lease trans-
actions that provide a special rule for mul-
tiple units of property subject to the same

Special Analyses
It has been determined that this Trea-
sury decision is not asignificant regula-
tory action as defined in Executive Order
12866. Therefore, a regulatory assessment
October 10, 20066432006–41 I.R.B.

is not required. It also has been deter-
mined that section 553(b) of the Admin-
istrative Procedure Act (5 U.S.C. chap-
ter 5) does not apply to these regulations
and, because these regulations do not im-
pose on small entities a collection of infor-
mation requirement, the Regulatory Flex-
ibility Act (5 U.S.C. chapter 6) does not
apply. Therefore, a Regulatory Flexibil-
ity Analysis is not required. Pursuant to
section 7805(f) of the Code, the notice of
proposed rulemaking was previously sub-
mitted to the Chief Counsel for Advocacy
of the Small BusinessAdministration for
comment on its impact on small business.
Drafting Information
The principal author of these regula-
tions is Douglas H. Kim, Office of As-
sociate Chief Counsel (Passthroughs and
Special Industries). However, other per-
sonnel from the IRS and Treasury Depart-
ment participated in their development.

Adoption of Amendments to the
Regulations
Accordingly, 26 CFR part 1 is amended
as follows:

Par. 3. Section 1.167(a)–14 is amended
by revising paragraphs (b)(1), (e)(2), and
(e)(3) to read as follows:
§1.167(a)–14 Treatment of certain
intangible property excluded from section
197.
*****
(b)***(1)In general. The amount
of the deduction for computer soft-
ware described in section 167(f)(1) and
§1.197–2(c)(4) is determined by amortiz-
ing the cost or other basis of the computer
software using the straight line method
described in §1.167(b)–1 (except that its
salvage value is treated as zero) and an
amortization period of 36 months begin-
ning on the first day of the month that the
computer software is placed in service.
Before determining the amortization de-
duction allowable under this paragraph
(b), the cost or other basis of computer
software that is section 179 property, as
defined in section 179(d)(1)(A)(ii), must
be reduced for any portion of the basis
the taxpayer properly elects to treat as
an expense under section 179. In addi-
tion, the cost or other basis of computer
software that is qualified property under
section 168(k)(2) or §1.168(k)–1, 50-per-
cent bonus depreciation property under
section 168(k)(4) or §1.168(k)–1, or qual-
ified New York Liberty Zone property
under section 1400L(b) or §1.1400L(b)–1,
must be reduced by the amount of the
additional first yeardepreciation deduc-
tion allowed or allowable, whichever is
greater, under section 168(k) or section
1400L(b) for the computer software. If
costs for developing computer software
that the taxpayer properly elects to defer
under section 174(b) result in the develop-
ment of property subject to the allowance
for depreciation under section 167, the
rules of this paragraph (b) will apply to the
unrecovered costs. In addition, this para-
graph (b) applies to the cost of separately
acquired computer software if the cost to
acquire the software is separately stated
and the cost is required to be capitalized
under section 263(a).

(iii)Unadjusted depreciable basisis the
basis of property for purposes of section
1011 without regard to any adjustments de-
scribed in section 1016(a)(2) and (3). This
basis reflects the reduction in basis for the
percentage of the taxpayer’s use of prop-
erty for the taxable year other than in the
taxpayer’s trade or business (or for the pro-
duction of income), for any portion of the
basis the taxpayer properly elects to treat
as an expense under section 179 or sec-
tion 179C, and for any adjustments to ba-
sis provided by other provisions of the In-
ternal Revenue Code and the regulations
thereunder (other than section 1016(a)(2)
and (3)) (for example, a reduction in basis
by the amount of the disabled access credit
pursuant to section 44(d)(7)). For property
subject to a lease, see section 167(c)(2).
*****
(b)Qualified property or 50-percent
bonus depreciation property—(1)In gen-
eral
. Qualified property or 50-percent
bonus depreciation property is deprecia-
ble property that meets all the following
requirements in the first taxable year in
which the property is subject to depre-
ciation by the taxpayer whether or not
depreciation deductions for the property
are allowable:
(i) The requirements in §1.168(k)–
1(b)(2) (description of property);
(ii) The requirements in §1.168(k)–
1(b)(3) (original use);
(iii) The requirements in §1.168(k)–
1(b)(4) (acquisition of property); and
(iv) The requirements in §1.168(k)–
1(b)(5) (placed-in-service date).
(2) * * *
(ii) * * *
(A) * * *
(2) Required to be depreciated under the
alternative depreciation system of section
168(g) pursuant to section 168(g)(1)(A)
through (D) or other provisions of the In-
ternal Revenue Code (for example, prop-
erty described in section 263A(e)(2)(A) if
the taxpayer (or any related person as de-
fined in section 263A(e)(2)(B)) has made
an election under section 263A(d)(3), or
property described in section 280F(b)(1)).
*****
(3) * * *
(i)In general. For purposes of the
30-percent additional first year deprecia-
tion deduction, depreciable property will
meet the requirements of this paragraph
(b)(3) if the original use of the prop-
erty commences with the taxpayer after
September 10, 2001. For purposes of the
50-percent additional first year deprecia-
tion deduction, depreciable property will
meet the requirements of this paragraph
(b)(3) if the original use of the property
commences with the taxpayer after May
5, 2003. Except as provided in paragraphs
(b)(3)(iii) and (iv) of this section, origi-
nal use means the first use to which the
property is put, whether or not that use
corresponds to the use of the property
by the taxpayer. Thus, additional capital
expenditures incurred by a taxpayer to re-
condition or rebuild property acquired or
owned by the taxpayer satisfies the orig-
inal use requirement. However, the cost
of reconditioned or rebuilt property does
not satisfy the original use requirement.
The question of whether property is recon-
ditioned or rebuilt property is a question
of fact. For purposes of this paragraph
(b)(3)(i), property that contains used parts
will not be treated as reconditioned or
rebuilt if the cost of the used parts is not
more than 20 percent of the total cost of
the property, whether acquired or self-con-
structed.
(ii)Conversion to business or income-
producing use—(A)Personal use to busi-
ness or income-producing use.Ifatax-
payer initially acquires new property for
personal use and subsequently uses the
property in the taxpayer’s trade or busi-
ness or for the taxpayer’s production of in-
come, the taxpayer is considered the orig-
inal user of the property. If a person ini-
2006–41 I.R.B.646October 10, 2006

tially acquires new property for personal
use and a taxpayer subsequently acquires
the property from the person for use in the
taxpayer’s trade or business or for the tax-
payer’s production of income, the taxpayer
is not considered the original user of the
property.
(B)Inventory to business or income-
producing use. If a taxpayer initially ac-
quires new property and holds the property
primarily for sale to customers in the ordi-
nary course of the taxpayer’s business and
subsequently withdraws the property from
inventory and uses the property primarily
in the taxpayer’s trade or business or pri-
marily for the taxpayer’s production of in-
come, the taxpayer is considered the orig-
inal user of the property. If a person ini-
tially acquires new property and holds the
property primarily for sale to customers in
the ordinary course of the person’s busi-
ness and a taxpayer subsequently acquires
the property from the person for use pri-
marily in the taxpayer’s trade or business
or primarily for the taxpayer’s production
of income, the taxpayer is considered the
original user of the property. For purposes
of this paragraph (b)(3)(ii)(B), the origi-
nal use of the property by the taxpayer
commences on the date on which the tax-
payer uses the property primarily in the
taxpayer’s trade or business or primarily
for the taxpayer’s production of income.
(iii)Sale-leaseback, syndication, and
certain other transactions.***
(B)Syndication transaction and certain
other transactions. If new property is orig-
inally placed in service by a lessor (includ-
ing by operation of paragraph (b)(5)(ii)(A)
of this section) after September 10, 2001
(for qualified property), or after May 5,
2003 (for 50-percent bonus depreciation
property), and is sold by the lessor or any
subsequent purchaser within three months
after the date the property was originally
placed in service by the lessor (or, in the
case of multiple units of property subject
to the same lease, within three months af-
ter the date the final unit is placed in ser-
vice, so long as the period between the
time the first unit is placed in service and
the time the last unit is placed in service
does not exceed 12 months), and the user
of the property after the last sale during
the three-month period remains the same
as when the property was originally placed
in service by the lessor, the purchaser of
the property in the last sale during the
three-month period is considered the orig-
inal user of the property.
(C)Sale-leaseback transaction fol-
lowed by a syndication transaction and
certain other transactions. If a sale-lease-
back transaction that satisfies the require-
ments in paragraph (b)(3)(iii)(A) of this
section is followed by a transaction that
satisfies the requirements in paragraph
(b)(3)(iii)(B) of this section, the original
user of the property is determined in ac-
cordance with paragraph (b)(3)(iii)(B) of
this section.
(iv)Fractional interests in property.If,
in the ordinary course of its business, a tax-
payer sells fractional interests in property
to third parties unrelated to the taxpayer,
each first fractional owner of the property
is considered as the original user of its pro-
portionate share of the property. Further-
more, if the taxpayer uses the property be-
fore all of the fractional interests of the
property are sold but the property contin-
uestobeheldprimarilyforsalebythetax-
payer, the original use of any fractional in-
terest sold to a third party unrelated to the
taxpayer subsequent to the taxpayer’s use
of the property begins with the first pur-
chaser of that fractional interest. * * *
(v) * * *
Example 4. * * * On June 1, 2003, G sells to
I, an unrelated party to G, the remaining unsold 3/8
fractional interests in the aircraft. * * *
Example 5. On September 1, 2001, JJ, an equip-
ment dealer, buys new tractors that are held by JJ pri-
marily for sale to customers in the ordinary course of
its business. On October 15, 2001, JJ withdraws the
tractors from inventory and begins to use the tractors
primarily for producing rental income. The holding
of the tractors by JJ as inventory does not constitute
a “use” for purposes of the original use requirement
and, therefore, the original use of the tractors com-
mences with JJ on October 15, 2001, for purposes of
paragraph (b)(3) of this section. However, the trac-
tors are not eligible for the additional first year de-
preciation deduction because JJ acquired the tractors
before September 11, 2001.

(B)50-percent bonus depreciation
property. For purposes of the 50-percent
additional first yeardepreciation deduc-
tion, depreciable property will meet the
requirements of this paragraph (b)(4) if
the property is—
(1) Acquired by the taxpayer after May
5, 2003, and before January 1, 2005, but
only if no written binding contract for the
acquisition of the property was in effect
before May 6, 2003; or

teredintoafterMay5,2003,andbefore
January 1, 2005.

sions of a supply or similar agreement state

(iii) * * *
(A) * * * If a taxpayer enters into a
written binding contract (as defined in
paragraph (b)(4)(ii) of this section) after
September 10, 2001, and before January 1,
2005, with another person to manufacture,
construct, or produce property described
in section 168(k)(2)(B) (longer production
period property) or section 168(k)(2)(C)
(certain aircraft) and the manufacture, con-
struction, or production of this property
begins after December 31, 2004, the ac-
quisition rule in paragraph (b)(4)(i)(A)(2)
or (B)(4)(i)(B)(2) of this section is met.
(B)When does manufacture, construc-
tion, or production begin—(1)In general.
For purposes of paragraph (b)(4)(iii) of
this section, manufacture, construction,
or production of property begins when
physical work of a significant nature be-
gins. Physical work does not include
preliminary activities such as planning
or designing, securing financing, explor-
ing, or researching. The determination
of when physical work of a significant
nature begins depends on the facts and
circumstances. For example, if a retail
motor fuels outlet or other facility is to be
constructed on-site, construction begins
when physical work of a significant nature
commences at the site; that is, when work
begins on the excavation for footings,
pouring the pads for the outlet, or the driv-
October 10, 20066472006–41 I.R.B.

ing of foundation pilings into the ground.
Preliminary work, such as clearing a site,
test drilling to determine soil condition,
or excavation to change the contour of
the land (as distinguished from excava-
tion for footings) does not constitute the
beginning of construction. However, if a
retail motor fuels outlet or other facility
is to be assembled on-site from modular
units manufactured off-site and delivered
to the site where the outlet will be used,
manufacturing begins when physical work
of a significant nature commences at the
off-site location.
(2)Safe harbor. For purposes of para-
graph (b)(4)(iii)(B)(1)ofthissection,a
taxpayer may choose to determine when
physical work of a significant nature be-
gins in accordance with this paragraph
(b)(4)(iii)(B)(2). Physical work of a sig-
nificant nature will not be considered to
begin before the taxpayer incurs (in the
case of an accrual basis taxpayer) or pays
(in the case of a cash basis taxpayer)
more than 10 percent of the total cost of
the property (excluding the cost of any
land and preliminary activities such as
planning or designing, securing financ-
ing, exploring, or researching). When
property is manufactured, constructed,
or produced for the taxpayer by another
person, this safe harbor test must be sat-
isfied by the taxpayer. For example, if a
retail motor fuels outlet or other facility
is to be constructed for an accrual basis
taxpayer by another person for the total
cost of $200,000 (excluding the cost of
any land and preliminary activities such as
planning or designing, securing financing,
exploring, or researching), construction
is deemed to begin for purposes of this
paragraph (b)(4)(iii)(B)(2) when the tax-
payer has incurred more than 10 percent
(more than $20,000) of the total cost of
the property. A taxpayer chooses to apply
this paragraph (b)(4)(iii)(B)(2) by filing
an income tax return for the placed-in-ser-
vice year of the property that determines
when physical work of a significant na-
ture begins consistent with this paragraph
(b)(4)(iii)(B)(2).
*****
(iv)Disqualified transactions—(A)In
general. Property does not satisfy the re-
quirements of this paragraph (b)(4) if the
user of the property as of the date on which
the property was originally placed in ser-
vice (including by operation of paragraphs
(b)(5)(ii), (iii), and (iv) of this section), or
a related party to the user or to the tax-
payer, acquired, or had a written binding
contract (as defined in paragraph (b)(4)(ii)
of this section) in effect for the acquisi-
tion of the property at any time before
September 11, 2001 (for qualified prop-
erty), or before May 6, 2003 (for 50-per-
cent bonus depreciation property). In addi-
tion, property manufactured, constructed,
or produced for the use by the user of the
property or by a related party to the user
or to the taxpayer does not satisfy the re-
quirements of this paragraph (b)(4) if the
manufacture, construction, or production
of the property for the user or the related
party began at any time before September
11, 2001 (for qualified property), or before
May 6, 2003 (for 50-percent bonus depre-
ciation property).
*****
(v) * * *
Example 10. * * * Between May 6, 2003, and
June 30, 2003, S, a calendar-year taxpayer, began
construction, and incurred another $1,200,000 to
complete the construction, of the power plant and, on
August 1, 2003, S placed the power plant in service.
***
Example 11. * * * In addition, the sale-leaseback
rules in paragraphs (b)(3)(iii)(A) and (b)(5)(ii)(A) of
this section do not apply because the equipment was
originally placed in service by T before September
11, 2001.
Example 12. On July 1, 2001, KK began con-
structing property for its own use. KK placed this
property in service on September 15, 2001. On Oc-
tober 15, 2001, KK sells the property to LL, an unre-
lated party, and leases the property back from LL in
a sale-leaseback transaction. Pursuant to paragraph
(b)(4)(iv) of this section, the property does not qual-
ify for the additional first year depreciation deduction
because the property was constructed for KK, the user
of the property, and that construction began prior to
September 11, 2001.
Example 13. On June 1, 2004, MM decided to
construct property described in section 168(k)(2)(B)
for its own use. However, one of the component parts
of the property had to be manufactured by another
person for MM. On August 15, 2004, MM entered
into a written binding contract with NN to acquire
this component part of the property for $100,000.
The manufacture of the component part commenced
on September 1, 2004, and MM received the com-
pleted component part on February 1, 2005. The
cost of this component part is 9 percent of the total
cost of the property to be constructed by MM. MM
began constructing the property described in sec-
tion 168(k)(2)(B) on January 15, 2005, and placed
this property (including all component parts) in ser-
vice on November 1, 2005. Pursuant to paragraph
(b)(4)(iii)(C)(2) of this section, the self-constructed
component part of $100,000 manufactured by NN for
MM is eligible for the additional first year deprecia-
tion deduction (assuming all other requirements are
met) because the manufacturing of the component
part began after September 10, 2001, and before Jan-
uary 1, 2005, and the property described in section
168(k)(2)(B), the larger self-constructed property,
was placed in service by MM before January 1, 2006.
However, pursuant to paragraph (b)(4)(iii)(A) of this
section, the cost of the property described in section
168(k)(2)(B) (excluding the cost of the self-con-
structed component part of $100,000 manufactured
by NN for MM) is not eligible for the additional first
year depreciation deduction because construction of
the property began after December 31, 2004.
Example 14. On December 1, 2004, OO entered
into a written binding contract (as defined in para-
graph (b)(4)(ii) of this section) with PP to manufac-
ture an aircraft described in section 168(k)(2)(C) for
use in OO’s trade or business. PP begins to manu-
facture the aircraft on February 1, 2005. OO places
the aircraft in service on August 1, 2005. Pursuant
to paragraph (b)(4)(iii)(A) of this section, the aircraft
meets the requirements of paragraph (b)(4)(i)(B)(2)
of this section because the aircraft was acquired by
OO pursuant to a written binding contract entered into
after May 5, 2003, and before January 1, 2005.
(5)Placed-in-service date—(i)In gen-
eral. Depreciable property will meet the
requirements of this paragraph (b)(5) if
the property is placed in service by the
taxpayer for use in its trade or business
or for production of income before Jan-
uary 1, 2005, or, in the case of property
described in section 168(k)(2)(B) or (C),
is placed in service by the taxpayer for
use in its trade or business or for pro-
duction of income before January 1, 2006
(or placed in service by the taxpayer for
use in its trade or business or for produc-
tion of income before January 1, 2007, in
the case of property described in section
168(k)(2)(B) or (C) to which section 105
of the Gulf Opportunity Zone Act of 2005
(Public Law 109–135, 119 Stat. 2577) ap-
plies (for further guidance, see Announce-
ment 2006–29, 2006–19 I.R.B. 879, and
§601.601(d)(2)(ii)(b)ofthischapter)).
(ii)Sale-leaseback, syndication, and
certain other transactions.***
(B)Syndication transaction and cer-
tain other transactions. If qualified prop-
erty is originally placed in service after
September 10, 2001, or 50-percent bonus
depreciation property is originally placed
in service after May 5, 2003, by a lessor
(including by operation of paragraph
(b)(5)(ii)(A) of this section) and is sold
by the lessor or any subsequent purchaser
withinthreemonthsafterthedatetheprop-
erty was originally placed in service by the
lessor (or, in the case of multiple units of
property subject to the same lease, within
three months after the date the final unit
2006–41 I.R.B.648October 10, 2006

is placed in service, so long as the period
between the time the first unit is placed in
service and the time the last unit is placed
in service does not exceed 12 months), and
the user of the property after the last sale
during this three-month period remains
the same as when the property was orig-
inally placed in service by the lessor, the
property is treated asoriginally placed in
service by the purchaser of the property in
the last sale during the three-month period
but not earlier than the date of the last sale.
(C)Sale-leaseback transaction fol-
lowed by a syndication transaction and
certain other transactions. If a sale-lease-
back transaction that satisfies the re-
quirements in paragraph (b)(5)(ii)(A) of
this section is followed by a transaction
that satisfies the requirements in para-
graph (b)(5)(ii)(B) of this section, the
placed-in-service date of the property is
determined in accordance with paragraph
(b)(5)(ii)(B) of this section.
*****
(v)Example. The application of this
paragraph (b)(5) is illustrated by the fol-
lowing example:
Example. On September 15, 2004, QQ acquired
and placed in service new equipment. This equip-
ment is not described in section 168(k)(2)(B) or (C).
On December 1, 2004, QQ sells the equipment to RR
and leases the equipment back from RR in a sale-
leaseback transaction. On February 15, 2005, RR
sells the equipment to TT subject to the lease with
QQ. As of February 15, 2005, QQ is still the user
of the equipment. The sale-leaseback transaction of
December 1, 2004, between QQ and RR satisfies the
requirements of paragraph (b)(5)(ii)(A) of this sec-
tion. The sale transaction of February 15, 2005, be-
tween RR and TT satisfies the requirements of para-
graph (b)(5)(ii)(B) of this section. Consequently, pur-
suant to paragraph (b)(5)(ii)(C) of this section, the
equipment is treated as originally placed in service by
TT on February 15, 2005. Further, pursuant to para-
graph (b)(3)(iii)(C) of this section, TT is considered
the original user of the equipment. Accordingly, the
equipment is not eligible for the additional first year
depreciation deduction.
*****
(d) * * *
(1) * * * (i)In general. Except as
provided in paragraph (f) of this section,
the additional first year depreciation de-
duction is allowable in the first taxable
year in which the qualified property or
50-percent bonus depreciation property is
placed in service by the taxpayer for use in
its trade or business or for the production
of income. Except as provided in para-
graph (f)(5) of this section, the allowable
additional first yeardepreciation deduc-
tion for qualified property is determined
by multiplying the unadjusted depreciable
basis (as defined in §1.168(k)–1(a)(2)(iii))
of the qualified property by 30 percent.
Except as provided in paragraph (f)(5) of
this section, the allowable additional first
year depreciation deduction for 50-percent
bonus depreciation property is determined
by multiplying the unadjusted depreciable
basis (as defined in §1.168(k)–1(a)(2)(iii))
of the 50-percent bonus depreciation prop-
erty by 50 percent. Except as provided in
paragraph (f)(1) of this section, the 30-per-
cent or 50-percent additional first year de-
preciation deduction is not affected by a
taxable year of less than 12 months. See
paragraph (f)(1) of this section for quali-
fied property or 50-percent bonus depreci-
ation property placed in service and dis-
posed of in the same taxable year. See
paragraph (f)(5) of this section for quali-
fied property or 50-percent bonus depreci-
ation property acquiredinalike-kindex-
change or as a result of an involuntary con-
version.
*****
(iii)Alternative minimum tax.The
30-percent or 50-percent additional first
year depreciation deduction is allowed
for alternative minimum tax purposes for
the taxable year in which the qualified
property or the 50-percent bonus depreci-
ation property is placed in service by the
taxpayer. In general, the 30-percent or
50-percent additional first year depreci-
ation deduction for alternative minimum
tax purposes is based on the unadjusted
depreciable basis of the property for alter-
native minimum tax purposes. However,
see paragraph (f)(5)(iii)(D) of this sec-
tion for qualified property or 50-percent
bonus depreciation property acquired in
a like-kind exchange or as a result of an
involuntary conversion.

that election applies for purposes of com-
puting the taxpayer’s alternative minimum
taxable income.
(7)Revocation of election—(i)In gen-
eral. Except as provided in paragraph
(e)(7)(ii) of this section, an election spec-
ified in paragraph (e)(1) of this section,
once made, may be revoked only with the
written consent of the Commissioner of
Internal Revenue. To seek the Commis-
sioner’s consent, the taxpayer must submit
a request for a letter ruling.
(ii)Automatic 6-month extension.If
a taxpayer made an election specified in
paragraph (e)(1) of this section for a class
of property, an automatic extension of 6
months from the due date of the taxpayer’s
Federal tax return (excluding extensions)
for the placed-in-service year of the class
of property is granted to revoke that elec-
tion, provided the taxpayer timely filed
the taxpayer’s Federal tax return for the
placed-in-service year of the class of prop-
erty and, within this 6-month extension pe-
riod, the taxpayer (and all taxpayers whose
tax liability would be affected by the elec-
tion) files an amended Federal tax return
for the placed-in-service year of the class
of property in a manner that is consistent
with the revocation of the election.

(2)Redetermination of basis. ***If
the unadjusted depreciable basis (as de-
fined in §1.168(k)–1(a)(2)(iii)) of quali-
fied property or 50-percent bonus depre-
ciation property is redetermined (for ex-
ample, due to contingent purchase price
or discharge of indebtedness) before Jan-
uary 1, 2005, or, in the case of property
described in section 168(k)(2)(B) or (C),
is redetermined before January 1, 2006 (or
redetermined before January 1, 2007, in
the case of property described in section
October 10, 20066492006–41 I.R.B.

168(k)(2)(B) or (C) to which section 105
of the Gulf Opportunity Zone Act of 2005
(Public Law 109–135, 119 Stat. 2577) ap-
plies (for further guidance, see Announce-
ment 2006–29, 2006–19 I.R.B. 879, and
§601.601(d)(2)(ii)(b)ofthischapter)),the
additional first year depreciation deduc-
tion allowable for the qualified property
or the 50-percent bonus depreciation prop-
erty is redetermined as follows:
*****
(ii)Decrease in basis. For the taxable
year in which a decrease in basis of qual-
ified property or 50-percent bonus depre-
ciation property occurs, the taxpayer shall
reduce the total amount otherwise allow-
able as a depreciation deduction for all
of the taxpayer’s depreciable property by
the excess additional first year deprecia-
tion deduction previously claimed for the
qualified property or the 50-percent bonus
depreciation property. If, for such taxable
year, the excess additional first year depre-
ciation deduction exceeds the total amount
otherwise allowable as a depreciation de-
duction for all of the taxpayer’s deprecia-
ble property, the taxpayer shall take into
account a negative depreciation deduction
in computing taxable income. The excess
additional first year depreciation deduc-
tion for qualified property is determined
by multiplying the amount of the decrease
in basis for this property by 30 percent.
The excess additional first year depreci-
ation deduction for 50-percent bonus de-
preciation property is determined by mul-
tiplying the amount of the decrease in ba-
sis for this property by 50 percent. For
purposes of this paragraph (f)(2)(ii), the
30-percent additional first year deprecia-
tion deduction applies to the decrease in
basis if the underlying property is quali-
fied property and the 50-percent additional
first year depreciation deduction applies
to the decrease in basis if the underly-
ing property is 50-percent bonus depreci-
ation property. Also, if the taxpayer es-
tablishes by adequate records or other suf-
ficient evidence that the taxpayer claimed
less than the additional first year deprecia-
tion deduction allowable for the qualified
property or the 50-percent bonus depreci-
ation property before the decrease in basis
or if the taxpayer claimed more than the
additional first year depreciation deduc-
tion allowable for the qualified property
or the 50-percent bonus depreciation prop-
erty before the decrease in basis, the ex-
cess additional first year depreciation de-
duction is determined by multiplying the
amount of the decrease in basis by the
additional first yeardepreciation deduc-
tion percentage actually claimed by the
taxpayer for the qualified property or the
50-percent bonus depreciation property, as
applicable, before the decrease in basis. To
determine the amount to reduce the total
amount otherwise allowable as a deprecia-
tion deduction for all of the taxpayer’s de-
preciable property for the excess deprecia-
tion previously claimed (other than the ad-
ditional first year depreciation deduction)
resulting from the decrease in basis of the
qualified property or the 50-percent bonus
depreciation property, the amount of the
decrease in basis of the qualified property
or the 50-percent bonus depreciation prop-
erty must be adjusted by the excess addi-
tional first year depreciation deduction that
reduced the total amount otherwise allow-
able as a depreciation deduction (as deter-
mined under this paragraph) and the re-
maining decrease in basis of—
(A) Qualified property or 50-percent
bonus depreciation property (except for
computer software described in paragraph
(b)(2)(i)(B) of this section) reduces the
amount otherwise allowable as a depreci-
ation deduction over the recovery period
of the qualified property or the 50-percent
bonus depreciation property, as applica-
ble, remaining as of the beginning of the
taxable year in which the decrease in basis
occurs, and using the same depreciation
method and convention of the qualified
property or 50-percent bonus depreciation
property, as applicable, that applies in the
taxable year in which the decrease in basis
occurs. If, for any taxable year, the reduc-
tion to the amount otherwise allowable as
a depreciation deduction (as determined
under this paragraph (f)(2)(ii)(A)) exceeds
the total amount otherwise allowable as a
depreciation deduction for all of the tax-
payer’s depreciable property, the taxpayer
shall take into account a negative depre-
ciation deduction incomputing taxable
income; and
(B) Computer software (as defined
in paragraph (b)(2)(i)(B) of this section)
that is qualified property or 50-percent
bonus depreciation property reduces the
amount otherwise allowable as a depre-
ciation deduction over the remainder
of the 36-month period (the useful life
under section 167(f)(1)) as of the be-
ginning of the first day of the month in
which the decrease in basis occurs. If,
for any taxable year, the reduction to the
amount otherwise allowable as a depreci-
ation deduction (as determined under this
paragraph (f)(2)(ii)(B)) exceeds the total
amount otherwise allowable as a depreci-
ation deduction for all of the taxpayer’s
depreciable property, the taxpayer shall
take into account a negative depreciation
deduction in computing taxable income.

(iv)***
Example 2. (i) On May 15, 2002, DD, a calen-
dar-year taxpayer, purchased and placed in service
qualified property that is 5-year property at a cost of
$400,000. To purchase the property, DD borrowed
$250,000 from Bank2. On May 15, 2003, Bank2 for-
gives $50,000 of the indebtedness. DD makes the
election provided in section 108(b)(5) to apply any
portion of the reduction under section 1017 to the ba-
sis of the depreciable property of the taxpayer. DD
depreciates the 5-year property placed in service in
2002 using the optional depreciation table that cor-
responds with the general depreciation system, the
200-percent declining balance method, a 5-year re-
covery period, and the half-year convention.
(ii) For 2002, DD is allowed a 30-percent addi-
tional first year depreciation deduction of $120,000
(the unadjusted depreciable basis of $400,000 mul-
tiplied by .30). In addition, DD’s depreciation
deduction allowable for 2002 for the remaining ad-
justed depreciable basis of $280,000 (the unadjusted
depreciable basis of $400,000 reduced by the addi-
tional first year depreciation deduction of $120,000)
is $56,000 (the remaining adjusted depreciable basis
of $280,000 multiplied by the annual depreciation
rate of .20 for recovery year 1).
(iii) For 2003, DD’s deduction for the re-
maining adjusted depreciable basis of $280,000 is
$89,600 (the remaining adjusted depreciable basis of
$280,000 multiplied by the annual depreciation rate
.32 for recovery year 2). Although Bank2 forgave
the indebtedness in 2003, the basis of the property
is reduced on January 1, 2004, pursuant to sections
108(b)(5) and 1017(a) under which basis is reduced
at the beginning of the taxable year following the
taxable year in which the discharge of indebtedness
occurs.
(iv) For 2004, DD’s deduction for the re-
maining adjusted depreciable basis of $280,000
is $53,760 (the remaining adjusted depreciable basis
of $280,000 multiplied by the annual depreciation
rate .192 for recovery year 3). However, pursuant to
paragraph (f)(2)(ii) of this section, DD must reduce
2006–41 I.R.B.650October 10, 2006

the amount otherwise allowable as a depreciation
deduction for 2004 by the excess depreciation pre-
viously claimed for the $50,000 decrease in basis
of the qualified property. Consequently, DD must
reduce the amount of depreciation otherwise allow-
able for 2004 by the excess additional first year
depreciation of $15,000 (the decrease in basis of
$50,000 multiplied by .30). Also, DD must reduce
the amount of depreciation otherwise allowable for
2004 by the excess depreciation attributable to the
remaining decrease in basis of $35,000 (the decrease
in basis of $50,000 reduced by the excess additional
first year depreciation of $15,000). The reduction
in the amount of depreciation otherwise allowable
for 2004 for the remaining decrease in basis of
$35,000 is $19,999 (the remaining decrease in basis
of $35,000 multiplied by .5714, which is equal to
1/remaining recovery period of 3.5 years at January
1, 2004, multiplied by 2). Accordingly, assuming the
qualified property is the only depreciable property
owned by DD, for 2004, DD’s total depreciation
deduction allowable for the qualified property is
$18,761 ($53,760 minus $15,000 minus $19,999).

remaining carryover basis and the remain-
ing excess basis, if any, of the acquired
MACRS property that is qualified property
or 50-percent bonus depreciation property
described in section 168(k)(2)(B) is lim-
ited to the total of the property’s remain-
ing carryover basis and remaining excess
basis, if any, attributable to the property’s
manufacture, construction, or production
after September 10, 2001 (for qualified
property), or May 5, 2003 (for 50-percent
bonus depreciation property), and before
January 1, 2005.
(D)Alternative minimum tax.The
30-percent or 50-percent additional first
year depreciation deduction is allowed for
alternative minimum tax purposes for the
year of replacement of acquired MACRS
property or acquired computer software
that is qualified property or 50-percent
bonus depreciation property. The 30-per-
cent or 50-percent additional first year
depreciation deduction for alternative
minimum tax purposes is based on the
remaining carryover basis and the remain-
ing excess basis, if any, of the acquired
MACRS property or the acquired com-
puter software for alternative minimum
tax purposes.

sion, a taxpayer acquires and places in
service the acquired MACRS property or
the acquired computer software before
the time of disposition of the involun-
tarily converted MACRS property or the
involuntarily converted computer soft-
ware and the time of disposition of the
involuntarily converted MACRS property
or the involuntarily converted computer

in the case of property described in sec-
tion 168(k)(2)(B) or (C) to which section
105 of the Gulf Opportunity Zone Act
of 2005 (Public Law 109–135, 119 Stat.

879, and §601.601(d)(2)(ii)(b)ofthis
chapter)), then—
(A)Time of replacement.Thetime
of replacement for purposes of this para-
graph (f)(5) is when the acquired MACRS
property or acquired computer software is
placed in service by the taxpayer, provided
the threat or imminence of requisition or
condemnation of the involuntarily con-
verted MACRS property or involuntarily
converted computer software existed be-
fore January 1, 2005, or, in the case of
property described in section 168(k)(2)(B)
or (C), existed before January 1, 2006
(or existed before January 1, 2007, in
the case of property described in section
168(k)(2)(B) or (C) to which section 105
of the Gulf Opportunity Zone Act of 2005
(Public Law 109–135, 119 Stat. 2577) ap-
plies (for further guidance, see Announce-
ment 2006–29, 2006–19 I.R.B. 879, and
§601.601(d)(2)(ii)(b)ofthischapter));and
(B)Depreciation of acquired MACRS
property or acquired computer software.
The taxpayer depreciates the acquired
MACRS property or acquired computer
software in accordance with paragraph (d)
of this section. However, at the time of
disposition of the involuntarily converted
MACRS property, the taxpayer deter-
mines the exchanged basis (as defined in
§1.168(i)–6T(b)(7)) and the excess basis
(as defined in §1.168(i)–6T(b)(8)) of the
acquired MACRS property and begins to
depreciate the depreciable exchanged ba-
sis (as defined in §1.168(i)–6T(b)(9))
of the acquired MACRS property in
accordance with §1.168(i)–6T(c). The
depreciable excess basis (as defined
in §1.168(i)–6T(b)(10)) of the acquired
MACRS property continues to be depreci-
ated by the taxpayer in accordance with the
first sentence of this paragraph. Further,
in the year of disposition of the invol-
untarily converted MACRS property, the
taxpayer must include in taxable income
the excess of the depreciation deductions
allowable, including the additional first
year depreciation deduction allowable, on
the unadjusted depreciable basis of the
acquired MACRS property over the ad-
ditional first year depreciation deduction
that would have been allowable to the tax-
payer on the remaining carryover basis of
the acquired MACRS property at the time
of replacement (as defined in paragraph
(f)(5)(v)(A) of this section) plus the depre-
ciation deductions that would have been
allowable, including the additional first
year depreciation deduction allowable, to
the taxpayer on the depreciable excess
basis of the acquired MACRS property
from the date the acquired MACRS prop-
erty was placed in service by the taxpayer
(taking into account the applicable con-
vention) to the time of disposition of the
involuntarily converted MACRS property.
Similar rules apply to acquired computer
software.
(vi)Examples. The application of this
paragraph (f)(5) is illustrated by the fol-
lowing examples:
Example 1. (i) In December 2002, EE, a calendar-
year corporation, acquired for $200,000 and placed
in service Canopy V1, a gas station canopy. Canopy
V1 is qualified property under section 168(k)(1) and
is 5-year property under section 168(e). EE depreci-
ated Canopy V1 under the general depreciation sys-
tem of section 168(a) by using the 200-percent declin-
ing balance method of depreciation, a 5-year recov-
ery period, and the half-year convention. EE elected
to use the optional depreciation tables to compute the
depreciation allowance for Canopy V1. On January
1, 2003, Canopy V1 was destroyed in a fire and was
no longer usable in EE’s business. On June 1, 2003,
in an involuntary conversion, EE acquired and placed
in service new Canopy W1 with all of the $160,000
of insurance proceeds EE received due to the loss of
Canopy V1. Canopy W1 is 50-percent bonus depre-
ciation property under section 168(k)(4) and is 5-year
property under section 168(e). Pursuant to paragraph
(g)(3)(ii) of this section and §1.168(i)–6T(k)(2)(i),
EE decided to apply §1.168(i)–6T to the involuntary
conversion of Canopy V1 with the replacement of
Canopy W1, the acquired MACRS property.

Example 3. (i) In December 2001, FF, a cal-
endar-year corporation, acquired for $10,000 and
placed in service Computer X2. Computer X2 is
qualified property under section 168(k)(1) and is
5-year property under section 168(e). FF depreciated
Computer X2 under the general depreciation system
of section 168(a) by using the 200-percent declining
balance method of depreciation, a 5-year recovery
period, and the half-year convention. FF elected
to use the optional depreciation tables to compute
the depreciation allowance for Computer X2. On
January 1, 2002, FF acquired new Computer Y2
by exchanging Computer X2 and $1,000 cash in a
like-kind exchange. Computer Y2 is qualified prop-
erty under section 168(k)(1) and is 5-year property
under section 168(e). Pursuant to paragraph (g)(3)(ii)
of this section and §1.168(i)–6T(k)(2)(i), FF decided
to apply §1.168(i)–6T to the exchange of Computer
X2 for Computer Y2, the acquired MACRS property.

Example 4. (i) In September 2002, GG, a June
30 year-end corporation, acquired for $20,000 and
placed in service Equipment X3. Equipment X3 is
qualified property under section 168(k)(1) and is
5-year property under section 168(e). GG depreci-
ated Equipment X3 under the general depreciation
system of section 168(a) by using the 200-percent
declining balance method of depreciation, a 5-year
recovery period, and the half-year convention. GG
elected to use the optional depreciation tables to
compute the depreciation allowance for Equipment
X3. In December 2002, GG acquired new Equip-
ment Y3 by exchanging Equipment X3 and $5,000
cash in a like-kind exchange. Equipment Y3 is qual-
ified property under section 168(k)(1) and is 5-year
property under section 168(e). Pursuant to paragraph
(g)(3)(ii) of this section and §1.168(i)–6T(k)(2)(i),
GG decided to apply §1.168(i)–6T to the exchange
of Equipment X3 for Equipment Y3, the acquired
MACRS property.

Example 5. (i)SamefactsasinExample 4.GG
depreciated Equipment Y3under the general depre-
ciation system of section 168(a) by using the 200-
percent declining balance method of depreciation, a

GG elected to use the optional depreciation tables to
compute the depreciation allowance for Equipment
Y3. On July 1, 2003, GG acquired new Equipment
Z1 by exchanging Equipment Y3 in a like-kind ex-
change. Equipment Z1 is 50-percent bonus depreci-
ation property under section 168(k)(4) and is 5-year
property under section 168(e). Pursuant to paragraph
(g)(3)(ii) of this section and §1.168(i)–6T(k)(2)(i),
GG decided to apply §1.168(i)–6T to the exchange
of Equipment Y3 for Equipment Z3, the acquired
MACRS property.

Example 6. (i) In April 2004, SS, a calendar
year-end corporation, acquired and placed in service
Equipment K89. Equipment K89 is 50-percent bonus
depreciation property under section 168(k)(4). In
November 2004, SS acquired and placed in service
used Equipment N78 by exchanging Equipment K89
in a like-kind exchange.
(ii) Pursuant to paragraph (f)(5)(iii)(B) of this
section, no additional first year deduction is al-
lowable for Equipment K89 and, pursuant to
§1.168(d)–1T(b)(3)(ii), no regular depreciation
deduction is allowable for Equipment K89, for the
taxable year ended December 31, 2004.
(iii) Equipment N78 is not qualified property un-
der section 168(k)(1) or 50-percent bonus depreci-
ation property under section 168(k)(4) because the
original use requirement of paragraph (b)(3) of this
section is not met. Accordingly, no additional first
year depreciation deduction is allowable for Equip-
ment N78.

(10)Coordination with section 47—(i)
In general. If qualified rehabilitation ex-
penditures (as defined in section 47(c)(2)
and §1.48–12(c)) incurred by a taxpayer
2006–41 I.R.B.652October 10, 2006

with respect to a qualified rehabilitated
building (as definedin section 47(c)(1)
and §1.48–12(b)) are qualified property
or 50-percent bonus depreciation property,
the taxpayer may claim the rehabilitation
credit provided by section 47(a) (provided
the requirements of section 47 are met)—
(A) With respect to the portion of the
basis of the qualified rehabilitated build-
ing that is attributable to the qualified re-
habilitation expenditures if the taxpayer
makes the applicable election under para-
graph (e)(1)(i) or (e)(1)(ii)(B) of this sec-
tion not to deduct any additional first year
depreciation for the class of property that
includes the qualified rehabilitation expen-
ditures; or
(B) With respect to the portion of the re-
maining rehabilitated basis of the qualified
rehabilitated building that is attributable
to the qualified rehabilitation expenditures
if the taxpayer claims the additional first
year depreciation deduction on the un-
adjusted depreciable basis (as defined in
paragraph (a)(2)(iii) of this section but be-
fore the reduction in basis for the amount
of the rehabilitation credit) of the qualified
rehabilitation expenditures and the tax-
payer depreciates the remaining adjusted
depreciable basis (as defined in paragraph
(d)(2)(i) of this section) of such expen-
ditures using straight line cost recovery
in accordance with section 47(c)(2)(B)(i)
and §1.48–12(c)(7)(i). For purposes of
this paragraph (f)(10)(i)(B), the remaining
rehabilitated basis is equal to the unad-
justed depreciable basis (as defined in
paragraph (a)(2)(iii) of this section but be-
fore the reduction in basis for the amount
of the rehabilitation credit) of the qual-
ified rehabilitation expenditures that are
qualified property or 50-percent bonus
depreciation property reduced by the ad-
ditional first year depreciation allowed or
allowable, whichever is greater.
(ii)Example. The application of this
paragraph (f)(10) is illustrated by the fol-
lowing example.
Example. (i) Between February 8, 2004, and
June 4, 2004, UU, a calendar-year taxpayer, incurred
qualified rehabilitation expenditures of $200,000
with respect to a qualified rehabilitated building
that is nonresidential real property under section
168(e). These qualified rehabilitation expenditures
are 50-percent bonus depreciation property and
qualify for the 10-percent rehabilitation credit un-
der section 47(a)(1). UU’s basis in the qualified
rehabilitated building is zero before incurring the
qualified rehabilitation expenditures and UU placed
the qualified rehabilitated building in service in July
2004. UU depreciates its nonresidential real property
placed in service in 2004 under the general depreci-
ation system of section 168(a) by using the straight
line method of depreciation, a 39-year recovery pe-
riod, and the mid-month convention. UU elected to
use the optional depreciation tables to compute the
depreciation allowance for its depreciable property
placed in service in 2004. Further, for 2004, UU did
not make any election under paragraph (e) of this
section.
(ii) Because UU did not make any election under
paragraph (e) of this section, UU is allowed a 50-per-
cent additional first year depreciation deduction of
$100,000 for the qualified rehabilitation expendi-
tures for 2004 (the unadjusted depreciable basis of
$200,000 (before reduction in basis for the rehabili-
tation credit) multiplied by .50). For 2004, UU also
is allowed to claim a rehabilitation credit of $10,000
for the remaining rehabilitated basis of $100,000
(the unadjusted depreciable basis (before reduction
in basis for the rehabilitation credit) of $200,000 less
the additional first year depreciation deduction of
$100,000). Further, UU’s depreciation deduction for
2004 for the remaining adjusted depreciable basis
of $90,000 (the unadjusted depreciable basis (before
reduction in basis for the rehabilitation credit) of
$200,000 less the additional first year depreciation
deduction of $100,000 less the rehabilitation credit
of $10,000) is $1,059.30 (the remaining adjusted
depreciable basis of $90,000 multiplied by the de-
preciation rate of .01177 for recovery year 1, placed
in service in month 7).
(11)Coordination with section
514(a)(3). The additional first year de-
preciation deduction is not allowable for
purposes of section 514(a)(3).

(6)Rehabilitation credit.Ifatax-
payer did not claim on a Federal tax
return for any taxable year ending on or
before September 1, 2006, the rehabil-
itationcreditprovidedbysection47(a)
with respect to the portion of the basis
of a qualified rehabilitated building that
is attributable to qualified rehabilitation
expenditures and the qualified rehabilita-
tion expenditures are qualified property
or 50-percent bonus depreciation prop-
erty, and the taxpayer did not make the
applicable election specified in paragraph
(e)(1)(i) or (e)(1)(ii)(B) of this section
for the class of property that includes
the qualified rehabilitation expenditures,
the taxpayer may claim the rehabilitation
credit for the remaining rehabilitated basis
(as defined in paragraph (f)(10)(i)(B) of
this section) of the qualified rehabilitated
building that is attributable to the qualified
rehabilitation expenditures (assuming all
the requirements of section 47 are met) in
accordance with paragraph (f)(10)(i)(B) of
this section by filing an amended Federal
tax return for the taxable year for which
the rehabilitation credit is to be claimed.
The amended Federal tax return must in-
clude the adjustment to the tax liability for
the rehabilitation credit and any collateral
adjustments to taxable income or to the
tax liability (for example, the amount of
depreciation allowed or allowable in that
taxable year for the qualified rehabilitated
building). Such adjustments must also be
made on amended Federal tax returns for
any affected succeeding taxable years.
Par. 10. Section 1.169–3 is amended
by revising paragraphs (a), (b)(2), and (g)
to read as follows:
§1.169–3 Amortizable basis.
(a)In general. The amortizable basis of
a certified pollution control facility for the
purpose of computing the amortization de-
duction under section 169 is the adjusted
basis of the facility for purposes of deter-
mining gain (see part II (section 1011 and
following), subchapter O, chapter 1 of the
Internal Revenue Code), in conjunction
with paragraphs (b), (c), and (d) of this
section. The adjusted basis for purposes
of determining gain (computed without
regard to paragraphs (b), (c), and (d) of
this section) of a facility that performs a
function in addition to pollution control,
or that is used in connection with more
than one plant or other property, or both,
is determined under §1.169–2(a)(3). For
rules as to additions and improvements to
October 10, 20066532006–41 I.R.B.

such a facility, see paragraph (f) of this
section. Before computing the amorti-
zation deduction allowable under section
169, the adjusted basis for purposes of de-
termining gain for a facility that is placed
in service by a taxpayer after September
10, 2001, and that is qualified property
under section 168(k)(2) or §1.168(k)–1,
50-percent bonus depreciation property
under section 168(k)(4) or §1.168(k)–1, or
qualified New York Liberty Zone property
under section 1400L(b) or §1.1400L(b)–1
must be reduced by the amount of the
additional first year depreciation deduc-
tion allowed or allowable, whichever is
greater, under section 168(k) or section
1400L(b), as applicable, for the facility.
(b) * * *
(2) If the taxpayer elects to begin the
60-month amortization period with the
first month of the taxable year succeeding
the taxable year in which the facility is
completed or acquired and a deprecia-
tion deduction is allowable under section
167 (including an additional first-year
depreciation allowance under former sec-
tion 179; for a facility that is acquired
by the taxpayer after September 10, 2001,
and that is qualified property under section
168(k)(2) or §1.168(k)–1 or qualified New
York Liberty Zone property under section
1400L(b) or §1.1400L(b)–1, the additional
first year depreciation deduction under
section 168(k)(1) or 1400L(b), as applica-
ble; and for a facility that is acquired by
the taxpayer after May 5, 2003, and that
is 50-percent bonus depreciation property
under section 168(k)(4) or §1.168(k)–1,
the additional first year depreciation de-
duction under section168(k)(4))with
respect to the facility for the taxable year
in which it is completed or acquired,
the amount determined under paragraph
(b)(1) of this section shall be reduced by
an amount equal to the amount of the de-
preciation deduction allowed or allowable,
whichever is greater, multiplied by a frac-
tion the numerator of which is the amount
determined under paragraph (b)(1) of this
section, and the denominator of which is
the facility’s total cost. The additional
first-year allowance for depreciation un-
der former section 179 will be allowable
only for the taxable year in which the fa-
cility is completed or acquired and only
if the taxpayer elects to begin the amorti-
zation deduction under section 169 with
the taxable year succeeding the taxable
year in which such facility is completed
or acquired. For a facility that is acquired
by a taxpayer after September 10, 2001,
and that is qualified property under sec-
tion 168(k)(2) or §1.168(k)–1 or qualified
New York Liberty Zone property under
section 1400L(b) or §1.1400L(b)–1, see
§1.168(k)–1(f)(4) or §1.1400L(b)–1(f)(4),
as applicable, with respect to when the
additional first yeardepreciation deduc-
tion under section 168(k)(1) or 1400L(b)
is allowable. For a facility that is acquired
by a taxpayer after May 5, 2003, and that
is 50-percent bonus depreciation property
under section 168(k)(4) or §1.168(k)–1,
see §1.168(k)–1(f)(4) with respect to
when the additional first year deprecia-
tion deduction under section 168(k)(4) is
allowable.

with respect to the portion of the basis of
a qualified rehabilitated building that is
attributable to qualified rehabilitation ex-
penditures and the qualified rehabilitation
expenditures are qualified New York Lib-
erty Zone property, and the taxpayer did
not make the election specified in para-
graph (e)(1) of this section for the class of
property that includes the qualified reha-
bilitation expenditures, the taxpayer may
claim the rehabilitation credit for the re-
maining rehabilitated basis (as defined in
§1.168(k)–1(f)(10)(i)(B)) of the qualified
rehabilitated building that is attributable
to the qualified rehabilitation expenditures
(assuming all the requirements of section
47 are met) in accordance with paragraph
(f)(9) of this section by filing an amended
Federal tax return for the taxable year for
which the rehabilitation credit is to be
claimed. The amended Federal tax return
must include the adjustment to the tax lia-
bility for the rehabilitation credit and any
collateral adjustments to taxable income
or to the tax liability (for example, the
amount of depreciation allowed or allow-
able in that taxable year for the qualified
rehabilitated building). Such adjustments
must also be made on amended Federal
tax returns for any affected succeeding
taxable years.

ACTION: Final regulations.
SUMMARY: This document contains final
regulations relating to the use of a nonac-
crual-experience method of accounting by
taxpayers using an accrual method of ac-
counting and performing services. The fi-
nal regulations reflect amendments under
the Job Creation andWorker Assistance
Act of 2002. The final regulations affect
qualifying taxpayers that want to adopt,
change to, or change a nonaccrual-experi-
ence method of accounting under section
448(d)(5) of the Internal Revenue Code
(Code).
DATES:Effective Date:These regulations
are effective September 6, 2006.
Applicability Date:These regulations
are applicable for taxable years ending on
or after August 31, 2006.
Comment Date:Written comments
must be received by January 4, 2007.
These regulations require that a tax-
payer’s nonaccrual-experience method
must be self-tested against the taxpayer’s
actual experience to determine whether
the nonaccrual-experience method clearly
reflects the taxpayer’s experience. The
determination of actual experience is re-
served in these regulations. Comments are
requested concerning how to determine
actual experience for purposes of timely
performing self-testing. Send submissions

Background
This document contains amendments
to the Income Tax Regulations (26 CFR
part 1) under section 448(d)(5). Section
448(d)(5) was enacted by section 801 of
the Tax Reform Act of 1986 (Public Law
99–514, 100 Stat. 2085) and was amended
by section 403 of the Job Creation and
Worker Assistance Act of 2002 (Public
Law 107–147, 116 Stat. 21) (JCWA),
effective for taxable years ending after
March 9, 2002. On September 4, 2003, the
IRS and Treasury Department published
in theFederal Register(68 FR 52543)
proposed amendments to the regulations
under section 448(d) by cross-reference to
temporary regulations (REG–141402–02,
2003–2 C.B. 932) and temporary regula-
tions (68 FR 52496) (T.D. 9090, 2003–2
C.B. 891) (collectively, the 2003 regula-
tions) relating to the limitation on the use
of the nonaccrual-experience method of
accounting under section 448(d)(5). A
public hearing was held on December 10,
2003. Written and electronic comments
responding to the proposed regulations
were received. After consideration of all
of the comments, the proposed regulations
are adopted as revised by this Treasury de-
cision, and the corresponding temporary
regulations are removed. The revisions
are discussed below.
Explanation of Provisions and Revisions
and Summary of Comments
1.Overview
These final regulations generally follow
the rules in the 2003 regulations. The fi-
nal regulations include the four safe harbor
nonaccrual-experience methods provided
in the 2003 regulations, but those methods
have been modified to provide more flexi-
bility. Unlike the 2003 regulations, the fi-
nal regulations do not require as a general
rule that a taxpayer’s nonaccrual-experi-
ence method be tested against one of the
safe harbor nonaccrual-experience meth-
ods. Instead, the final regulations adopt,
with modifications, the general rule from
the 2003 regulations as a fifth safe harbor.
The final regulations also adopt a new gen-
eral rule that requires a taxpayer’s nonac-
crual-experience method be tested against
actual experience unless the taxpayer has
adopted one of the five safe harbor meth-
ods. These final regulations apply to tax-
able years ending on or after August 31,
2006.
Certain portions of the 2003 regula-
tions have been removed or incorporated
into other paragraphs of the final regu-
lations. Section 1.448–2T(d) regarding
certain receivables for which the nonac-
crual-experience method is not allowed
has been combined with §1.448–2(c)
in the final regulations. Special rules
in various parts of the 2003 regulations
such as §1.448–2T(e)(2)(ii) and (iii),
1.448–2T(e)(3)(iii), 1.448–2T(e)(4)(ii)
and (iii), and 1.448–2T(e)(5)(ii) and (iii),
have been combined with the special
rules in §1.448–2T(e)(7) and are now in
§1.448–2(b), (c), and (d) of the final regu-
lations. Most of §1.448–2T(g), (h), and (j)
of the 2003 regulations relating to methods
of accounting and audit protection have
been removed. The IRS and Treasury
Department intend to issue administrative
guidance that will contain procedures for
certain changes in a nonaccrual-experi-
ence method of accounting. The general
rule that a nonaccrual-experience method
is a method of accounting to which sec-
tions 446 and 481 apply has been moved
to §1.448–2(b).
Other portions of the 2003 regulations
have been moved to a new definitions and
special rules paragraph in §1.448–2(c) of
the final regulations. Section 1.448–2T(d)
regarding accounts receivable is included
in a definition of accounts receivable in
§1.448–2(c)(1) of the final regulations.
Other terms in the definitions paragraph
include applicable period, bad debts,
charge-offs, determination date, recover-
ies, and uncollectible amount. The final
regulations incorporate these definitions,
as appropriate, throughout. For exam-
ple, in the 2003 regulations the four safe
harbor methods include bad debts in the
numerator; however, safe harbor 2 did not
refer to bad debts, but instead described
them as “accounts receivable actually de-
termined to be uncollectible and charged
off....” These descriptions should not be
interpreted differently. Therefore, the final
regulations use the defined termbad debts
in each numerator. Finally, the examples
are changed to conform to other changes
within the final regulations.
2.Self-Testing Requirement
The 2003 regulations provide that a
taxpayer may use any nonaccrual-expe-
rience method of accounting, provided
the taxpayer’s method meets the self-test
requirements. The self-testing in the 2003
regulations requires a taxpayer to com-
pare its proposed nonaccrual-experience
method with one of the four safe harbor
methods to determine whether the tax-
payer’s proposed method clearly reflects
experience. Self-testing is required in the
first taxable year to determine whether
the proposed method is allowed (first-year
self-testing requirement) and, if allowed,
self-testing is required every three taxable
years thereafter (three-year self-testing
requirement). The final regulations pro-
vide, as a general rule, that a taxpayer may
use any nonaccrual-experience method
of accounting that clearly reflects the
taxpayer’s experience. The final regula-
tions provide that taxpayers must self-test
October 10, 20066572006–41 I.R.B.

against the taxpayer’s actual experience
to determine whether a method clearly
reflects the taxpayer’s experience unless
the taxpayer has adopted one of the five
safe harbor methods. The final regulations
reserve on the definition of actual experi-
ence.
a.Appropriateness of self-testing
requirement
Many commentators suggested that
taxpayers should not be required to incur
additional expenses to develop a separate
system for performing the self-test, noting
that it would be burdensome and impracti-
cal for the majority of taxpayers using an
alternative nonaccrual-experience method
to conduct the self-test due to the limita-
tions of their existing automated record
keeping systems. One commentator sug-
gested that the self-test was outside the
scope of the JCWA and legislative intent.
These commentators all recommended
that the final regulations omit the self-test-
ing requirement.
The JCWA provides that “[a] taxpayer
may adopt, or ... change to, a computa-
tion or formula that clearly reflects the
taxpayer’s experience,” and that “[a] re-
quest [to change] shall be approved if
such computation or formula clearly re-
flects the taxpayer’s experience.” Public
Law 107–147, section 403(a). Taxpayers
and the IRS must be able to determine
whether a nonaccrual-experience method
clearly reflects the taxpayer’s experience.
The Secretary has broad authority to de-
termine whether a method of accounting
clearly reflects the taxpayer’s income.
A self-testing requirement is consistent
with the statute, because it is the manner
by which taxpayers and the IRS deter-
mine whether a nonaccrual-experience
method clearly reflects the taxpayer’s
experience, and thus, clearly reflects the
taxpayer’s income. Taxpayers must be
able to show that a nonaccrual-experience
method clearly reflects experience prior
to adopting or changing to the method.
The requirement to self-test provides an
objective standard for making the deter-
mination. Therefore, the final regulations
do not adopt the recommendation to omit
a self-testing requirement and retain the
rule that a taxpayer must maintain books
and records sufficient to prove that the
taxpayer’s nonaccrual-experience method
clearly reflects its experience for the tax-
able year of the exclusion.
b.Standard for comparison
Commentators stated that the self-test-
ing requirements do not allow taxpayers
the opportunity to demonstrate that a pro-
posed method clearly reflects their experi-
ence, because under the 2003 regulations
all methods must be compared to one of
the safe harbors. The commentators stated
that none of the safe harbors reflect ac-
tual experience, because all of the safe har-
bors are moving averages rather than a
comparison of the estimated uncollectible
amount for a taxable year under the tax-
payer’s nonaccrual-experience method to
the actual collection experience of that tax-
able year’s accounts receivable. Thus, the
commentators stated, the safe harbors may
or may not reflect actual experience as well
as the proposed method.
The final regulations modify the
self-testing requirements in response to
these comments and eliminate the re-
quirement in the 2003 regulations that a
taxpayer’s nonaccrual-experience method
must be tested against one of the four safe
harbor methods. The final regulations
require that the taxpayer’s nonaccrual-ex-
perience method must be tested against the
taxpayer’s actual experience, unless the
taxpayer is using one of the safe harbor
nonaccrual-experience methods, which
are deemed to clearly reflect experience.
For taxpayers and the IRS to imple-
ment and administer the nonaccrual-ex-
perience method, the determination of
actual experience is necessary. Although
commentators stated that taxpayers should
be allowed to use hindsight and that ac-
tual experience would require the use of
data reflecting the portion of the subject
accounts receivable that remain uncol-
lectible, the commentators did not elabo-
rate regarding what “remain uncollectible”
means, nor did the commentators set the
date at which accounts receivable “re-
main uncollectible.” The determination
and proof of actual experience generally is
a simple matter for taxpayers whose col-
lection process with respect to the subject
receivables is complete by the time the
Federal income tax return is filed. The
collection cycle for some taxpayers, how-
ever, may routinely span several taxable
years. The commentators did not elaborate
how such a factual determination could be
made prior to filing the Federal income
tax return for the applicable taxable year
(or alternatively, prior to filing the method
change request for the applicable tax-
able year) in cases in which a taxpayer’s
collection cycle for the receivables goes
beyond the date for the filing of the return
(or method change). For taxpayers with a
longer collection process, the determina-
tion of the final actual experience is not
possible by the time the Federal income
tax return is filed, and may continue to be
incomplete upon examination by the IRS,
if the taxpayer’s collection process with
respect to receivables is still in process.
Additionally, it is possible that accounts
receivable written off in one taxable year
may be recovered several taxable years
later, even for taxpayers whose average
collection cycle is short. Therefore, the
final regulations reserve the determination
of actual experience.
The IRS and Treasury Department an-
ticipate providing future guidance that
may change or restrict the rules for
self-testing and may address the deter-
mination of actual experience. In the
meantime, taxpayers may request advance
consent to use a method other than a safe
harbor method, but in the request taxpay-
ers must establish to the satisfaction of the
Commissioner how the determination of
actual experience is made. Comments are
requested concerning how to determine
actual experience. Specifically, the IRS
and Treasury Department seek comments
on how the use of hindsight data can be
made administrable. For example, how
will the IRS National Office have the nec-
essary data furnished with the application
for change in method of accounting, and
how will the taxpayer be able to timely per-
form the self-testing? In particular, should
one, fixed determination date be used as
a cut-off for all information included in
the determination of actual experience?
What facts and circumstances, known by
the filing deadline for a change in method
of accounting and thefiling deadline for
an original Federal income tax return, can
a taxpayer and the IRS rely on to deter-
mine the taxpayer’s actual experience for
purposes of the first-year self-testing re-
quirements for the application for change
in method of accounting and for purposes
of the three-year self-testing requirements
for the filing of the Federal income tax
2006–41 I.R.B.658October 10, 2006

return? For a taxpayer that is applying
to adopt or change to a nonaccrual-ex-
perience method of accounting, should
thetaxpayerbeallowedtorelyonthe
results under the proposed method for the
current taxable yearcompared to actual
experience for old taxable years rather
than a comparison of the results under the
proposed method for the current taxable
year compared to actual experience for the
current taxable year at the time of filing,
provided the taxpayer can demonstrate
that there is not a change in the type of
a substantial portion of the outstanding
accounts receivable such that the risk of
loss is substantially decreased? What
standards should apply to a taxpayer who
has had a change in the type of a substan-
tial portion of the outstanding accounts
receivable? If a taxpayer’s business has
changed in a manner that impacts a sub-
stantial portion of its outstanding accounts
receivable, the taxpayer’s historical data
for its receivables could lose much of their
relevance in determining the taxpayer’s
current nonaccrual experience.
c.Safe harbor comparison method
The final regulations retain a modified
version of the self-test from the 2003 reg-
ulations, which required the comparison
of a taxpayer’s method against one of
the safe harbors. The safe harbor com-
parison method in the final regulations
is used in conjunction with the fifth safe
harbor nonaccrual-experience method,
which allows a taxpayer to use any nonac-
crual-experience method provided the
method meets the safe harbor comparison
method of self-testing. The safe harbor
comparison method provided in the final
regulations allows a taxpayer to com-
pare the taxpayer’s method against any of
thesafeharbors1through4duringany
self-testing period,rather than requiring
the safe harbor chosen for comparison
to be treated as a method of accounting.
Because any of the safe harbors 1 through
4 are deemed to clearly reflect experience,
a taxpayer should be able to compare
its method against any of the safe har-
bors 1 through 4 to determine whether its
method clearly reflects experience. The
IRS and Treasury Department anticipate
that the procedures for changes in method
of accounting to use the new safe har-
bor nonaccrual-experience method will
be provided in administrative guidance,
and that these changes will be made with
automatic consent.
d.Methods that do not clearly reflect
experience
The 2003 regulations provide, as part
of the three-year self-test requirement,
that if the taxpayer’s cumulative alterna-
tive nonaccrual-experience amount ex-
cluded from income during the test period
exceeds the taxpayer’s cumulative safe
harbor nonaccrual-experience amount, the
taxpayer must recapture the excess into
income in the third taxable year of the
three-year self-test. The IRS and Trea-
sury Department intended this recapture
provision to allow minor variances or
fluctuations produced by the taxpayer’s
nonaccrual-experience method without
prohibiting continued use of the method.
However, when the taxpayer’s nonac-
crual-experience method produces results
that are more than minor variations or
fluctuations from the three-year self-test
amounts, the method does not clearly
reflect the taxpayer’s experience. The
recapture provision addresses situations
in which the taxpayer’s nonaccrual-expe-
rience method generally clearly reflects
experience, but the taxpayer has an anoma-
lous taxable year in which the method does
not clearly reflect experience. However,
methods may consistently provide large
distortions from the taxpayer’s actual ex-
perience in future taxable years despite
meeting the requirements of the first-year
self-test. Consequently, the final regu-
lations include a limit in the three-year
self-testing provisions that, if exceeded,
deems the taxpayer’s nonaccrual-experi-
ence method to not clearly reflect the tax-
payer’s experience. Because the taxpayer
must recapture the difference between the
uncollectible amount under the taxpayer’s
nonaccrual-experience method and the
taxpayer’s actual experience, a change
from the taxpayer’s nonaccrual-experi-
ence method to a permissible method in
the subsequent taxable year does not re-
quire a section 481(a) adjustment and is
made on a cut-off basis.
Additionally, to provide transparency,
the IRS and Treasury Department intend
to provide in future guidance descriptions
of methods and characteristics of methods
combined with specific taxpayer circum-
stances that do not clearly reflect experi-
ence.
e.Other
Commentators suggested that the
self-test was not administrable in the con-
text of consolidated groups. The IRS and
Treasury Department believe that the final
regulations do not impose more burden
than any other method of accounting in
the context of a consolidated group. Gen-
erally, methods of accounting, including
the nonaccrual-experience method with its
self-testing requirement, are adopted and
applied separately by each entity within
the consolidated group (or to separate
trades or businesses within an entity), not
at the consolidated group level.
3.Safe Harbor Methods
The 2003 regulations have four safe
harbors: safe harbor 1 (the six-year mov-
ing average method), safe harbor 2 (the
actual experience method), safe harbor 3
(the modified BlackMotor method), and
safe harbor 4 (the modified moving aver-
age method). Comments were received re-
garding safe harbors 1, 2, and 4. No com-
ments were received regarding safe harbor
3.
a.General issues
Commentators questioned the need to
impose different time periods for different
safe harbor methods. For example, in the
2003 regulations, safe harbors 1, 3 and 4
are based on a six-year period (the current
taxable year and the five immediately pre-
ceding taxable years), whereas safe har-
bor 2 is based on a three year period (the
current taxable year and the two imme-
diately preceding taxable years). These
commentators recommended that, for con-
sistency, the safe harbor methods should
permit taxpayers to compute the uncol-
lectible amounts using a period consisting
of the current taxable year and no fewer
than the two immediately preceding tax-
able years and no more than the five im-
mediately preceding taxable years.
Providing options among the safe har-
bors, including those with different time
periods, is consistent with legislative in-
tent to provide taxpayers “with alterna-
tive computations or formulas that taxpay-
ers may rely upon.” Different taxpayers
October 10, 20066592006–41 I.R.B.

may choose different methods with differ-
ent time periods based on their individ-
ual circumstances and experience. The fi-
nal regulations allow taxpayers flexibility
to choose a period of at least three tax-
able years, but not more than six taxable
years (applicable period), for purposes of
the computations in each of the safe har-
bors. The taxable years included in the
applicable period must be the most recent
(which may or may not include the cur-
rent taxable year, as applicable) and must
be consecutive.
Additionally, commentators stated
that including the current taxable year in
computations can cause difficulties when
preparing computations for estimated
taxes. Therefore, the final regulations
allow taxpayers flexibility with regard
to whether the current taxable year is
included in the applicable period. The
choice of which taxable years and how
many are included in the applicable pe-
riod is part of the taxpayer’s method of
accounting under a safe harbor, and can
be changed only with the consent of the
Commissioner. Taxpayers making such
a change may not have all the historical
data necessary to compute a section 481(a)
adjustment. Therefore, the final regula-
tions provide that the change is done on
a cut-off basis rather than with a section
481(a) adjustment.
Finally, some commentators reiterated
their earlier suggestion that the Black
Motor formula should be permitted as an
additional safe harbor method. The IRS
and Treasury Department continue to con-
clude that the Black Motor formula should
not be provided as an additional safe har-
bor method because the formula overstates
the uncollectible amount in many circum-
stances. The final regulations add a fifth
safe harbor, which, as discussed above,
allows taxpayers to use any alternative
nonaccrual-experience method provided
the method meets the requirements of
the safe harbor comparison method under
the self-testing requirements. The IRS
and Treasury Department may provide
additional safe harbors through future
published guidance. In addition, if a tax-
payer does not wish to rely on one of the
safe harbors, the final regulations pro-
vide that a taxpayer may use any other
alternative nonaccrual-experience method
provided the method clearly reflects its
experience and the taxpayer requests and
receives consent from the Commissioner
to use such method.
Commentators requested that the regu-
lations specifically include a statement that
unintentional or immaterial variances will
not cause a taxpayer to be changed to the
specific charge-off method. As discussed
in the preamble to the 2003 regulations, the
IRS and Treasury Department do not con-
template that a taxpayer be changed to the
specific charge-off method due to uninten-
tional or immaterial variances, especially
if a taxpayer is disadvantaged by the vari-
ances. Such a rule is unnecessary, partic-
ularly with the flexibility added to each of
thesafeharbors.
b.Safe harbor 1 — revenue-based moving
average method
Safe harbor 1 in the 2003 regulations
was referred to as the six-year moving
average method. It is renamed the rev-
enue-based moving average method in the
final regulations to reflect the flexibility to
choose between three to six taxable years
for the applicable period. The final regula-
tions provide that the revenue-based mov-
ing average percentage of safe harbor 1
(the ratio of net write-offs for the applica-
ble period over accounts receivable earned
over the same applicable period) is multi-
plied by a taxpayer’s accounts receivable
balance at the end of the taxable year to de-
termine the taxpayer’s nonaccrual-experi-
ence amount.
A commentator suggested that a safe
harbor method should be added that would
modify safe harbor 1 to multiply the rev-
enue-based moving average percentage by
a taxpayer’s total billings (accounts receiv-
able earned during the taxable year in lieu
of its accounts receivable balance at the
end of the taxable year). The commen-
tator suggested that this new safe harbor
would provide symmetry between the de-
nominator of the revenue-based moving
average percentage and the amount against
which the revenue-based moving average
percentage is multiplied.
The final regulations do not adopt this
recommendation. The IRS and Treasury
Department previously analyzed the ef-
fects of multiplying the revenue-based
moving average percentage by the to-
tal billings during the taxable year and
determined that this computation over-
states that portion of the taxpayer’s
year-end accounts receivable balance
that will not be collected. The existing
formula is the method provided in for-
mer §1.448–2T(e)(2), as contained in T.D.
8194, 53 FR 12513 (1988). Although
the denominator and multiplicand are not
symmetrical, the method accurately re-
flects the year-end receivables that will
not be collected for taxpayers with a short
collection cycle.
c.Safe harbor 2 — actual experience
method
Under safe harbor 2 of the 2003 reg-
ulations, the taxpayer’s adjusted nonac-
crual-experience amount is determined
by tracking the receivables in the tax-
payer’s accounts receivable balance at the
beginning of the current taxable year to
determine the dollar amount of the ac-
counts receivable actually determined to
be uncollectible and charged off and not
recovered or determined to be collectible
by the determination date. The determi-
nation date is the date selected by the
taxpayer for the taxable year for purposes
of safe harbor 2, and may not be later than
the earlier of the due date, including ex-
tensions, for filing the taxpayer’s Federal
income tax return for that taxable year or
the date on which the taxpayer timely files
the return for that taxable year. Under Op-
tion A of safe harbor 2, the computation
is repeated for the taxpayer’s accounts re-
ceivable balance at the beginning of each
of the two immediately preceding taxable
years. Under Option B of safe harbor 2,
taxpayers that do not have the information
necessary to compute a three-year moving
average in the first taxable year the method
is used are allowed to transition into the
method year-by-year. The total of the
amounts determined to be uncollectible is
divided by the total beginning accounts
receivable balance for those taxable years
used in the computation to determine the
taxpayer’s three-year (Option A), or up
to three-year (Option B), moving average
percentage. This percentage is then mul-
tiplied by the taxpayer’s current year-end
accounts receivable balance to arrive at
the taxpayer’s actual nonaccrual-expe-
rience amount. The taxpayer’s actual
nonaccrual-experience amount is then
multiplied by 1.05 to determine the tax-
payer’s adjusted nonaccrual-experience
amount.
2006–41 I.R.B.660October 10, 2006

As discussed above, the final regula-
tions allow flexibility in the applicable pe-
riod used in safe harbor 2. Additionally,
because the final regulations provide defi-
nitions of terms used throughout the regu-
lations for consistency, the terms used to
describe the safe harbor 2 formula were
changed to conform to the definitions in
the final regulations. Although the de-
scription of the method may look as though
it has changed substantially, the safe har-
bor 2 method is not intended to operate
differently than the 2003 regulations, other
than the flexibility in the applicable period
and, as discussed below, the flexibility in
the determination dates and in tracing re-
coveries.
Some commentators requested clarifi-
cation as to whether safe harbor 2 is based
on a computation that takes into account
all known information arising both before
and after the determination date. The com-
mentators suggested that the 2003 regula-
tions may be interpreted as taking into ac-
count only all known information arising
on or before determination dates for previ-
ous taxable years involved in the compu-
tation.
The computation in safe harbor 2, Op-
tion A, in the final regulations, contem-
plates consideration of all known informa-
tion arising on or before the determina-
tion date for the current taxable year, in-
cluding beginning accounts receivable bal-
ances, charge-offs and recoveries, with re-
spect to all taxable years included in the
computation. For example, if an account
receivable of a calendar year taxpayer ex-
ists on January 1, 2006, and is charged off
as a bad debt on December 15, 2007, the
bad debt should be included in the com-
putation in the taxable year it is charged
off and every subsequent taxable year for
as long as the 2006 beginning of the year
accounts receivable balance is part of the
computation under this method. Conse-
quently, the final regulations clarify that all
known information arising on or before the
determination date for the current taxable
year, with respect to the taxable years in-
cluded in the computation, should be con-
sidered.
In the 2003 regulations, Option B al-
lows a taxpayer to transition into the ac-
tual experience safe harbor method. The
final regulations allow a new taxpayer with
no beginning accounts receivable to transi-
tion under either Option A or Option B (see
§1.448–2(d)(4) of the final regulations).
Option B in the final regulations differs
from Option A in that it allows a taxpayer
to use multiple determination dates (one
for each taxable year of the applicable pe-
riod) instead of one determination date.
Therefore, under Option B in the final reg-
ulations, a taxpayer has a choice of the ap-
plicable period, three to six taxable years,
and the taxpayer uses separate determina-
tion dates for each taxable year in the ap-
plicable period. Thatis, a taxpayer must
use bad debts sustained by the separate de-
termination date of each taxable year dur-
ing the applicable period rather than bad
debts sustained by the determination date
of the current taxable year. The determina-
tion date used for each taxable year must
be the determination date originally used
for each taxable year at the time the uncol-
lectible amount for that taxable year was
computed. For example, if an account re-
ceivable of a calendar year taxpayer ex-
ists on January 1, 2006, and is charged off
as a bad debt on December 15, 2007, and
the determination date for the 2006 tax-
able year is September 1, 2007, the bad
debt would never be included in the com-
putation because it is charged off after the
2006 taxable year determination date. This
method was requested by commentators
to reduce the burden of having to update
the total bad debts for a particular taxable
year with every future computation that in-
cluded that taxable year.
Other commentators requested clarifi-
cation as to whether the determination date
used in safe harbor 2 may shift from year to
year. These commentators recommended
that the final regulations confirm that a tax-
payer may use a different determination
date each taxable year, and that a change
of determination date is not a change in
method of accounting. Safe harbor 2 con-
templates that a taxpayer may file its Fed-
eral income tax return at different times
from year to year, and that the choice of
a determination date used in the computa-
tion is not a method of accounting. How-
ever, once a determination date is selected
and used for a particular taxable year, it
may not be changed for that taxable year.
Therefore, the final regulations clarify that
the determination date may be different
from year to year, and that a change in
the determination date is not a change in
method of accounting.
Under Option B of safe harbor 2, the
2003 regulations provide that a newly
formed taxpayer that chooses Option B
and does not have any accounts receivable
upon formation will not be able to exclude
any portion of its year-end accounts re-
ceivable from income for its first taxable
year because the taxpayer does not have
any accounts receivable on the first day
of the taxable year that can be tracked.
Some commentators recommended that
the final regulations either permit newly
formed taxpayers using Option B to ex-
clude a portion of their year-end accounts
receivable balance, or in the alternative,
clarify the rules for adopting this safe
harbor in the taxpayer’s first taxable year
in order to eliminate the administrative
burden of filing Form 3115, “Applica-
tion for Change in Accounting Method,”
in the succeeding taxable year. The fi-
nal regulations retain this special rule in
§1.448–(d)(4) for both safe harbor 2 and
safe harbor 4, because the methods require
a beginning accounts receivable balance
to compute the uncollectible amount. Use
of another method in the first taxable year
may not clearly reflect experience. The
final regulations clarify that the taxpayer
must begin creating its moving average
in its second taxable year by tracking the
accounts receivable as of the first day of
its second taxable year. The use of one
of the safe harbor nonaccrual-experience
methods of accounting described in para-
graph (f)(2), (f)(4), or (f)(5), if applicable,
of the final regulations in a taxpayer’s
second taxable year in this situation is
not a change in method of accounting.
Although the taxpayer must maintain the
books and records necessary to perform
the computations under the adopted safe
harbor nonaccrual-experience method, the
taxpayer is not required to affirmatively
elect the method on its Federal income tax
return for its first taxable year.
Commentators requested that safe har-
bor 2 be modified to permit taxpayers to
use any reasonable method to determine
recoveries. In response to commentators’
concerns about whether taxpayers could
use assumptions regarding recoveries
rather than specifically trace, the preamble
to the 2003 regulations stated that the IRS
and Treasury Department do not intend
that a taxpayer be changed to the specific
charge off method due to unintentional
and/or immaterial variances, especially
October 10, 20066612006–41 I.R.B.

if the taxpayer is disadvantaged by such
variances. Some commentators believe
that despite the preamble, the 2003 regula-
tions may require taxpayers to specifically
trace 100% of recoveries. The IRS and
Treasury Department did not intend to pre-
vent taxpayers from using a method that
allocates 100% of recoveries to current
taxable year bad debts. Commentators
also have stated that although some recov-
eries may be traceable, some recoveries
may not be traceable due to lump sum
recoveries from third parties.
The final regulations provide that a tax-
payer specifically should trace recoveries
ifthetaxpayerisabletodosowithout
undue burden. However, the IRS and
Treasury Department believe if the tax-
payer is unable specifically to trace all
recoveries without undue burden, the tax-
payer should be able to use any reasonable
method in determining the amount of re-
coveries to be traced to each taxable year’s
bad debts. Therefore, the final regulations
allow taxpayers to use a reasonable alloca-
tion method. A method will be considered
reasonable if there is a cause and effect
relationship between the allocation base
or ratio and the recoveries. The final reg-
ulations also provide that a taxpayer may
trace only recoveries that are traceable
and allocate the remaining, untraceable,
recoveries to charge-offs of amounts in
the relevant beginning accounts receiv-
able balances. Methods that include, for
example, receivablesfor which the nonac-
crual-experience method is not allowed to
be used (see §1.448–2(c)(1)(ii)) generally
will not be considered reasonable.
d.Safe harbor 3 — modified Black Motor
method
Safe harbor 3 is a variation of the for-
mula addressed inBlack Motor Co. v.
Commissioner, 41 B.T.A. 300 (1940),
aff’d, 125 F.2d 977 (6
th
Cir. 1942). No
comments were received regarding safe
harbor 3. The final regulations adopt the
method in the 2003 regulations, with mi-
nor revisions made to the terms used in
the formulas to conform the terms used
throughout the regulations.
e.Safe harbor 4 — modified moving
average method
The 2003 regulations provide that, for
purposes of safe harbor 4, a taxpayer may
determine the uncollectible amount by
multiplying its accounts receivable bal-
ance at the end of the current taxable year
by the ratio of total bad debts charged off
for the current taxable year and the five
preceding taxable years other than the
credit charges (accounts receivable) that
were charged off in the same taxable year
they were generated, adjusted for recov-
eries of charge-offs during that period, to
the sum of accounts receivable at the end
of the current taxable year and the five
preceding taxable years.
Some commentators argued that, by
eliminating credit charges that were writ-
ten off in the same taxable year they were
generated, the effect of this computation
for a taxpayer’s first taxable year is to
eliminate the intended benefit of section
448(d)(5). These commentators recom-
mended that the final regulations permit
newly formed taxpayers using safe harbor
4 to exclude a portion of their year-end
accounts receivable balance, or in the al-
ternative, clarify the rules on adopting
this safe harbor method in the taxpayer’s
first taxable year in order to eliminate the
administrative burden of filing Form 3115
in the succeeding taxable year.
This safe harbor method, like safe har-
bor 3, is a variation of the formula ad-
dressed inBlack Motor Co. v. Com-
missioner. Safe harbor 4, by eliminat-
ing credit charges that were written off
in the same taxable year they were gen-
erated, and thereby reducing the amount
computed under the traditional Black Mo-
tor formula, remedies known shortcom-
ings generally associated with the Black
Motor formula, and as such, more accu-
rately reflects a taxpayer’s nonaccrual-ex-
perience. Therefore, the final regulations
retain this rule.
Another commentator pointed out that
there is a mismatching in the compari-
son of write-offs to accounts receivable
in the formula used in safe harbor 4 be-
cause it compares the total accounts writ-
ten off in a taxable year after the year of
sale to the ending balances in accounts re-
ceivable for the six-year period. For exam-
ple, the sum of the write-offs in each tax-
able year for the preceding taxable years’
charges for services in year 7 is for ser-
vices rendered in years 1 through 6, but the
ending balances in accounts receivable are
from years 2 through 7. This commenta-
tor opined that, if charges for services and
accounts receivable are increasing, the ra-
tio of write-offs from prior balances rel-
ative to current receivables would be un-
derstated and therefore the uncollectible
amount would be understated. The com-
mentator suggested that the sum of the
write-offs in each taxable year for the pre-
ceding taxable years’ charges for services
should be divided by the sum of the be-
ginning accounts receivable for the current
and five preceding taxable years. The fi-
nal regulations adopt this recommendation
and, for purposes of safe harbor 4, the de-
nominator is changed to reflect the begin-
ning of the taxable year accounts receiv-
able balances in lieu of accounts receivable
balances at the end of the taxable year.
4.Special Rules
a.Acquisitions and dispositions
A commentator recommended that
the final regulations clarify that newly
formed or acquired taxpayers in a section
351(a) or 721(a) nontaxable transaction
are allowed to use predecessor data to
compute their uncollectible amount under
the nonaccrual-experience method. The
final regulations adopt this comment and
provide special rules for acquisitions and
dispositions. Taxpayers that acquire a
major portion of a trade or business or a
unit of a trade or business (for example, a
hospital) should include the data from the
predecessor in the computations to avoid
potentially skewing the computations for
the remainder of the applicable period.
Additionally, taxpayers that dispose of
a major portion of a trade or business
or a unit of a trade or business should
not use the data related to the disposed
trade or business in the computations. For
purposes of the nonaccrual-experience
methods of accounting, a new, qualified
taxpayer that acquires property in any
transaction to which section 381(a) does
not apply must adopt a nonaccrual-ex-
perience method on the basis of its own
experience. However, to the extent pre-
decessor information is available, the data
must be used in the newly-adopted nonac-
crual-experience method.
b.Reportable transactions
Some commentators recommended
that the book-tax difference that may
2006–41 I.R.B.662October 10, 2006

result from the use of the nonaccrual-ex-
perience method not be taken into account
in determining whether a transaction is a
reportable transaction for purposes of the
disclosure rules under §1.6011–4(b)(6).
As a result of Notice 2006–6, 2006–5
I.R.B. 385, book-tax differences no
longer create reportable transactions un-
der §1.6011–4(b)(6). Therefore, it is not
necessary to adopt this recommendation.
c.Short taxable years
As discussed, the 2003 regulations gen-
erally provide procedures for taxpayers
that have fewer than the requisite num-
ber of taxable years to adopt or change
to a safe harbor nonaccrual-experience
method. Some commentators requested
rules on how taxpayers may compute their
nonaccrual-experience amount in the case
of a short taxable year. Commentators
opined that for certain safe harbors, such
as safe harbors 2, 3 and 4, inaccurate in-
come exclusion can arise because a short
taxable year will have a disproportionate
effect on the numerator and denominator
of the computations. For example, a tax-
payer that has a relatively stable balance
of accounts receivable but a short period,
such as three months, may generate only
one-fourth of the normal write-offs. These
commentators recommended that the fi-
nal regulations provide that, if a taxpayer
experiences a short taxable year, the net
write-offs for the short period should be
annualized in order to prevent distortion
of the safe harbor computation. Alterna-
tively, these commentators suggested that
taxpayers should be allowed to include
data from the previous twelve months in
the safe harbor computation. For example,
for a calendar year taxpayer who experi-
ences a short period ending March 31
st
,the
taxpayer would use data from the twelve
months prior to the period ending on
March 31
st
to compute its nonaccrual-ex-
perience amount.
The final regulations provide that tax-
payers must make appropriate adjustments
for short taxable years for nonaccrual-ex-
perience methods that are based on a com-
parison of accounts receivable balance to
total bad debts. The IRS and Treasury
Department intend to issue administrative
guidance on appropriate adjustments.
d.Periodic systems
As with the 2003 regulations, the fi-
nal regulations provide, in §1.448–2(d)(2),
that a taxpayer applies its nonaccrual-ex-
perience method with respect to each spe-
cific account receivable eligible for the
method. The preamble to the 2003 regu-
lations states that a taxpayer may continue
to use the periodic system described in No-
tice 88–51, 1988–1 C.B. 535, in conjunc-
tion with any permissible nonaccrual-ex-
perience method used by the taxpayer. The
use of a periodic method remains permis-
sible under §1.448–2(d)(2) of the final reg-
ulations.
5.Effective date
These final regulations are applicable to
taxable years ending on or after August 31,
2006. A commentator recommended that
the final regulationsbe applied retroac-
tively to allow taxpayers to settle any open
taxable year in which the nonaccrual-ex-
perience method is an issue under consid-
eration in examination, in Appeals, or be-
fore the U.S. Tax Court by using one of
the safe harbor methods, and thus, avoid
continued disagreements between the gov-
ernment and taxpayers. The final regula-
tions do not adopt this recommendation.
However, the Commissioner may settle an
earlier taxable year on the basis of a safe
harbor method that clearly reflects the tax-
payer’s experience.
6.Procedures for Adoption or Change in
Method of Accounting
The 2003 regulations include specific
rules for filing an application to change to a
nonaccrual-experience method of account-
ing. The final regulations omit these rules,
which will be provided in administrative
guidance. The guidance will include auto-
matic consent procedures for filing an ap-
plication to change to one of the safe har-
bor nonaccrual-experience methods of ac-
counting.
To adopt or change to a method other
than one of the safe harbor nonaccrual-
experience methods of accounting, a tax-
payer must request advance consent under
the current procedures for obtaining the
consent of the Commissioner of Internal
Revenue to change a method of account-
ing for Federal income tax purposes (see,
for example, Rev. Proc. 97–27, 1997–1
C.B. 680 (as modified and amplified by
Rev. Proc. 2002–19, 2002–1 C.B. 696,
as amplified and clarified by Rev. Proc.
2002–54, 2002–2 C.B. 432). In the in-
terest of sound tax administration, a new
taxpayer must request advance consent to
adopt a method other than one of the safe
harbor nonaccrual-experience methods to
ensure that the method clearly reflects in-
come and experience.
Special Analyses
It has been determined that this Trea-
sury decision is not asignificant regula-
tory action as defined in Executive Order
12866. Therefore, a regulatory assessment
is not required. It also has been determined
that section 553(b) and (d) of the Admin-
istrative Procedure Act (5 U.S.C. chapter
5) does not apply to these regulations. It is
hereby certified that the collection of infor-
mation contained in these regulations will
not have a significant regulatory impact on
a substantial number of small entities. This
certification is based upon the fact that the
estimated burden associated with the in-
formation collection averages three hours
per respondent. Moreover, for taxpayers
that are eligible to use these regulations
and that follow these regulations, any bur-
den due to the collection of information
in these regulations will be outweighed by
the benefit received by accruing less in-
come than would otherwise be required.
Accordingly, a regulatory flexibility anal-
ysis is not required. Pursuant to section
7805(f) of the Internal Revenue Code, the
proposed regulations preceding these reg-
ulations were submitted to the Chief Coun-
sel for Advocacy of the Small Business
Administration for comment on their im-
pact on small business.
Drafting Information
The principal author of these regula-
tions is W. Thomas McElroy, Jr. of the Of-
fice of Associate Chief Counsel (Income
Tax and Accounting). However, other per-
sonnel from the IRS and Treasury Depart-
ment participated in their development.
*****
Adoption of Amendments to the
Regulations
Accordingly, 26 CFR parts 1 and 602
are amended as follows:
October 10, 20066632006–41 I.R.B.

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 1.448–2 is added to read
as follows:
§1.448–2 Nonaccrual of certain amounts
by service providers.
(a)In general. This section applies
to taxpayers qualified to use a nonac-
crual-experience method of accounting
provided for in section 448(d)(5) with
respect to amounts to be received for the
performance of services. A taxpayer that
satisfies the requirements of this section
is not required to accrue any portion of
amounts to be received from the perfor-
mance of services that, on the basis of the
taxpayer’s experience, and to the extent
determined under the computation or for-
mula used by the taxpayer and allowed
under this section, will not be collected.
Except as otherwise provided in this sec-
tion, a taxpayer is qualified to use a nonac-
crual-experience method of accounting if
the taxpayer uses an accrual method of
accounting with respect to amounts to be
received for the performance of services
by the taxpayer and either—
(1) The services are in fields referred
to in section 448(d)(2)(A) and described in
§1.448–1T(e)(4) (health, law, engineering,
architecture, accounting, actuarial science,
performing arts, or consulting); or
(2) The taxpayer meets the $5 million
annual gross receipts test of section 448(c)
and §1.448–1T(f)(2) for all prior taxable
years.
(b)Application of method and treat-
ment as method of accounting.Therules
of section 448(d)(5) and the regulations
are applied separately to each taxpayer.
For purposes of section 448(d)(5), the
termtaxpayerhas the same meaning
as the termpersondefined in section
7701(a)(1) (rather than the meaning of the
term defined in section 7701(a)(14)). The
nonaccrual of amounts to be received for
the performance of services is a method
of accounting (a nonaccrual-experience
method). A change to a nonaccrual-expe-
rience method, from one nonaccrual-expe-
rience method to another nonaccrual-ex-
perience method, or to a periodic system
(for example, see Notice 88–51, 1988–1
C.B. 535, and §601.601(d)(2)(ii)(b)of
this chapter), is a change in method of
accounting to which the provisions of
sections 446 and 481 and the regulations
apply. See also paragraphs (c)(2)(i), (c)(5),
(d)(4), and (e)(3)(i) of this section. Except
as provided in other published guidance, a
taxpayer who wishes to adopt or change to
any nonaccrual-experience method other
than one of the safe harbor methods de-
scribed in paragraph (f) of this section
must request and receive advance consent
from the Commissioner in accordance
with the applicable administrative proce-
dures issued under §1.446–1(e)(3)(ii) for
obtaining the Commissioner’s consent.
(c)Definitions and special rules—(1)
Accounts receivable—(i)In general.Ac-
counts receivable include only amounts
that are earned by a taxpayer and other-
wise recognized in income through the
performance of services by the taxpayer.
For purposes of determining a taxpayer’s
nonaccrual-experience under any method
provided in this section, amounts de-
scribed in paragraph (c)(1)(ii) of this
section are not taken into account. Except
as otherwise provided, for purposes of
this section, accounts receivable do not
include amounts that are not billed (such
as for charitable or pro bono services)
or amounts contractually not collectible
(such as amounts in excess of a fee sched-
ule agreed to by contract). See paragraph
(g)Examples 1and2of this section for
examples of this rule.
(ii)Method not available for certain
receivables—(A)Amounts not earned
and recognized through the performance
of services. A nonaccrual-experience
method of accounting may not be used
with respect to amountsthat are not earned
by a taxpayer and otherwise recognized
in income through the performance of
services by the taxpayer. For example, a
nonaccrual-experience method may not be
used with respect to amounts owed to the
taxpayer by reason of the taxpayer’s activ-
ities with respect to lending money, selling
goods, or acquiringaccounts receivable
or other rights to receive payment from
other persons (including persons related
to the taxpayer) regardless of whether
those persons earned the amounts through
the provision of services. However, see
paragraph (d)(3) of this section for special
rules regarding acquisitions of a trade or
business or a unit of a trade or business.
(B)If interest or penalty charged on
amounts due. A nonaccrual-experience
method of accounting may not be used
with respect to amounts due for which in-
terestisrequiredtobepaidorforwhich
there is any penalty for failure to timely
pay any amounts due. For this purpose,
a taxpayer will be treated as charging in-
terest or penalties for late payment if the
contract or agreement expressly provides
for the charging of interest or penalties for
late payment, regardless of the practice of
the parties. If the contract or agreement
does not expressly provide for the charg-
ing of interest or penalties for late pay-
ment, the determination of whether the tax-
payer charges interest or penalties for late
payment will be made based on all of the
facts and circumstances of the transaction,
and not merely on the characterization by
the parties or the treatment of the transac-
tion under state or local law. However, the
offering of a discount for early payment
of an amount due will not be regarded as
the charging of interest or penalties for late
payment under this section, if—
(1) The full amount due is otherwise
accrued as gross income by the taxpayer at
the time the services are provided; and
(2) The discount for early payment is
treated as an adjustment to gross income in
the year of payment, if payment is received
within the time required for allowance of
the discount. See paragraph (g)Example 3
of this section for an example of this rule.
(2)Applicable period—(i)In general.
The applicable period is the number of tax-
able years on which the taxpayer bases its
nonaccrual-experience method. A change
in the number of taxable years included in
the applicable period is a change in method
of accounting to which the procedures of
section 446 apply. A change in the in-
clusion or exclusion of the current taxable
year in the applicable period is a change
in method of accounting to which the pro-
cedures of section 446 apply. A change in
the number of taxable years included in the
applicable period or the inclusion or exclu-
sion of the current taxable year in the ap-
plicable period is made on a cut-off basis.
(ii)Applicable period for safe harbors.
For purposes of the safe harbors under
paragraph (f) of this section the applica-
ble period may consist of at least three but
not more than six of the immediately pre-
ceding consecutive taxable years. Alter-
natively, the applicable period may con-
2006–41 I.R.B.664October 10, 2006

sist of the current taxable year and at least
two but not more than five of the immedi-
ately preceding consecutive taxable years.
A period shorter than six taxable years is
permissible only if the period contains the
most recent preceding taxable years and all
of the taxable years in the applicable pe-
riod are consecutive.
(3)Bad debts. Bad debts are accounts
receivable determined to be uncollectible
and charged off.
(4)Charge-offs. Amounts charged off
include only those amounts that would oth-
erwise be allowable under section 166(a).
(5)Determination date. The determi-
nation date in safe harbor 2 provided in
paragraph (f)(2) of this section is used as
a cut-off date for determining all known
data to be taken into account in the com-
putation of the taxableyear’s uncollectible
amount. The determination date may not
be later than the earlier of the due date,
including extensions, for filing the tax-
payer’s Federal income tax return for that
taxable year or the date on which the tax-
payer timely files the return for that taxable
year. The determination date may be dif-
ferent in each taxable year. However, once
a determination date is selected and used
for a particular taxable year, it may not be
changed for that taxable year. The choice
of a determination date is not a method of
accounting.
(6)Recoveries. Recoveries are amounts
previously excluded from income under a
nonaccrual-experience method or charged
off that the taxpayer recovers.
(7)Uncollectible amount.Theun-
collectible amount is the portion of any
account receivable amount due that, un-
der the taxpayer’s nonaccrual-experience
method, will be not collected.
(d)Use of experience to estimate un-
collectible amounts—(1)In general.In
determining the portion of any amount
due that, on the basis of experience, will
not be collected, a taxpayer may use any
nonaccrual-experience method that clearly
reflects the taxpayer’s nonaccrual-expe-
rience. The determination of whether
a nonaccrual-experience method clearly
reflects the taxpayer’s nonaccrual-experi-
ence is made in accordance with the rules
under paragraph (e) of this section. Alter-
natively, the taxpayer may use any one of
the five safe harbornonaccrual-experience
methods of accounting provided in para-
graphs (f)(1) through (f)(5) of this section,
which are presumed to clearly reflect a
taxpayer’s nonaccrual-experience.
(2)Application to specific accounts
receivable. The nonaccrual-experience
method is applied with respect to each
account receivable of the taxpayer that is
eligible for this method. With respect to a
particular account receivable, the taxpayer
determines, in the manner prescribed in
paragraphs (d)(1) or (f)(1) through (f)(5)
of this section (whichever applies), the un-
collectible amount. The determination is
required to be made only once with respect
to each account receivable, regardless of
the term of the receivable. The uncol-
lectible amount is notrecognized as gross
income. Thus, the amount recognized as
gross income is the amount that would
otherwise be recognized as gross income
with respect to the account receivable, less
the uncollectible amount. A taxpayer that
excludes an amount from income during a
taxable year as a result of the taxpayer’s
use of a nonaccrual-experience method
may not deduct in any subsequent taxable
year the amount excluded from income.
Thus, the taxpayer may not deduct the
excluded amount in a subsequent taxable
year in which the taxpayer actually de-
termines that the amount is uncollectible
and charges it off. If a taxpayer using a
nonaccrual-experience method determines
that an amount that was not excluded from
income is uncollectible and should be
charged off (for example, a calendar-year
taxpayer determines on November 1
st
that
an account receivable that was originated
on May 1
st
of the same taxable year is un-
collectible and should be charged off), the
taxpayer may deduct the amount charged
off when it is charged off, but must include
any subsequent recoveries in income. The
reasonableness of a taxpayer’s determi-
nation that amounts are uncollectible and
should be charged off may be considered
on examination. See paragraph (g)Exam-
ple 12of this section for an example of
this rule.
(3)Acquisitions and dispositions—(i)
Acquisitions. If a taxpayer acquires the
major portion of a trade or business of
another person (predecessor) or the major
portion of a separate unit of a trade or busi-
ness of a predecessor, then, for purposes of
applying this section for any taxable year
ending on or after the acquisition, the ex-
perience from preceding taxable years of
the predecessor attributable to the portion
of the trade or business acquired, if avail-
able, must be used in determining the tax-
payer’s experience.
(ii)Dispositions. If a taxpayer disposes
of a major portion of a trade or business
or the major portion of a separate unit
of a trade or business, and the taxpayer
furnished the acquiring person the infor-
mation necessary for the computations re-
quired by this section, then, for purposes of
applying this section for any taxable year
ending on or after the disposition, the expe-
rience from preceding taxable years attrib-
utable to the portion of the trade or busi-
ness disposed may not be used in determin-
ing the taxpayer’s experience.
(iii)Meaning of terms. For the mean-
ing of the termsacquisition,separate unit,
andmajor portion, see paragraph (b) of
§1.52–2. The termacquisitionincludes an
incorporation or a liquidation.
(4)New taxpayers. The rules of this
paragraph (d)(4) apply to any newly
formed taxpayer to which the rules of
paragraph (d)(3)(i) of this section do not
apply. Any newly formed taxpayer that
wants to use a safe harbor nonaccrual-ex-
perience method of accounting described
in paragraph (f)(1), (f)(2), (f)(3), (f)(4),
or (f)(5) of this section applies the meth-
ods by using the experience of the actual
number of taxable years available in the
applicable period. A newly formed tax-
payer that wants to use one of the safe
harbor nonaccrual-experience methods of
accounting described in paragraph (f)(2),
(f)(4), or (f)(5) of this section in its first
taxable year and does not have any ac-
counts receivable upon formation may
not exclude any portion of its year-end
accounts receivable from income for its
first taxable year. The taxpayer must
begin creating its moving average in its
second taxable year by tracking the ac-
counts receivable as of the first day of its
second taxable year. The use of one of the
safe harbor nonaccrual-experience meth-
ods of accounting described in paragraph
(f)(2), (f)(4), or (f)(5) of this section in
a taxpayer’s second taxable year in this
situation is not a change in method of
accounting. Although the taxpayer must
maintain the books and records necessary
to perform the computations under the
adopted safe harbor nonaccrual-experi-
ence method, the taxpayer is not required
to affirmatively elect the method on its
October 10, 20066652006–41 I.R.B.

Federal income tax return for its first tax-
able year.
(5)Recoveries. Regardless of the
nonaccrual-experience method of ac-
counting used by a taxpayer under this
section, the taxpayer must take recoveries
into account. If, in a subsequent taxable
year, a taxpayer recovers an amount pre-
viously excluded from income under a
nonaccrual-experience method or charged
off, the taxpayer must include the recov-
ered amount in income in that subsequent
taxable year. See paragraph (g)Example
13of this section for an example of this
rule.
(6)Request to exclude taxable years
from applicable period. A period shorter
than the applicable period generally is per-
missible only if the period consists of con-
secutive taxable years and there is a change
in the type of a substantial portion of the
outstanding accounts receivable such that
the risk of loss is substantially increased.
A decline in the general economic condi-
tions in the area, which substantially in-
creases the risk of loss, is a relevant fac-
tor in determining whether a shorter pe-
riod is appropriate. However, approval to
use a shorter period will not be granted
unless the taxpayer supplies evidence that
the accounts receivable outstanding at the
close of the taxable years for the shorter
period requested are more comparable in
nature and risk to accounts receivable out-
standing at the close of the current taxable
year. A substantial increase in a taxpayer’s
bad debt experience is not, by itself, suffi-
cient to justify the use of a shorter period.
If approval is granted to use a shorter pe-
riod, the experience for the excluded tax-
able years may not be used for any subse-
quent taxable year. A request for approval
to exclude the experience of a prior taxable
year must be made in accordance with the
applicable procedures for requesting a let-
ter ruling and must include a statement of
the reasons the experience should be ex-
cluded. A request will not be considered
unless it is sent to the Commissioner at
least 30 days before the close of the first
taxable year for which the approval is re-
quested.
(7)Short taxable years. A taxpayer
with a short taxable year that uses a nonac-
crual-experience method that compares
accounts receivable balance to total bad
debts during the taxable year should make
appropriate adjustments.
(8)Record keeping requirements—(i)
A taxpayer using a nonaccrual-experience
method of accounting must keep sufficient
books and records to establish the amount
of any exclusion from gross income un-
der section 448(d)(5) for the taxable year,
including books and records demonstrat-
ing—
(A) The nature of the taxpayer’s nonac-
crual-experience method;
(B) Whether, for any particular tax-
able year, the taxpayer qualifies to use its
nonaccrual-experience method (including
the self-testing requirements of paragraph
(e) of this section (if applicable));
(C) The taxpayer’s determination that
amounts are uncollectible;
(D) The proper amount that is exclud-
able under the taxpayer’s nonaccrual-ex-
perience method; and
(E) The taxpayer’s determination date
under paragraph (c)(5) of this section (if
applicable).
(ii) If a taxpayer does not maintain
records of the data that are sufficient to es-
tablish the amount of any exclusion from
gross income under section 448(d)(5)
for the taxable year, the Internal Rev-
enue Service may change the taxpayer’s
method of accounting on examination.
See §1.6001–1 for rules regarding records.
(e)Requirements for nonaccrual
method to clearly reflect experience—(1)
In general. A nonaccrual-experience
method clearly reflects the taxpayer’s ex-
perience if the taxpayer’s nonaccrual-ex-
perience method meets the self-test re-
quirements described in this paragraph
(e). If a taxpayer is using one of the safe
harbor nonaccrual-experience methods
described in paragraphs (f)(1) through
(f)(4) of this section, its method is deemed
to clearly reflect its experience and is not
subject to the self-testing requirements in
paragraphs (e)(2) and (e)(3) of this section.
(2)Requirement to self-test—(i)In
general. A taxpayer using, or desiring
to use, a nonaccrual-experience method
must self-test its nonaccrual-experience
method for its first taxable year for which
the taxpayer uses, or desires to use, that
nonaccrual-experience method (first-year
self-test) and everythree taxable years
thereafter (three-year self-test). Each
self-testmustbeperformed by comparing
the uncollectible amount (under the tax-
payer’s nonaccrual-experience method)
with the taxpayer’s actual experience. A
taxpayer using the safe harbor under para-
graph (f)(5) of this section must self-test
using the safe harbor comparison method
in paragraph (e)(3) of this section.
(ii)First-year self-test. The first-year
self-test must be performed by compar-
ing the uncollectible amount with the tax-
payer’s actual experience for its first tax-
able year for which the taxpayer uses, or
desires to use, that nonaccrual-experience
method. If the uncollectible amount for the
first-year self-test is less than or equal to
the taxpayer’s actual experience for its first
taxable year for which the taxpayer uses, or
desires to use, that nonaccrual-experience
method, the taxpayer’s nonaccrual-experi-
ence method is treated as clearly reflect-
ing its experience for the first taxable year.
If, as a result of the first-year self-test, the
uncollectible amount for the test period is
greater than the taxpayer’s actual experi-
ence, then—
(A) The taxpayer’s nonaccrual-experi-
ence method is treated as not clearly re-
flecting its experience;
(B) The taxpayer is not permitted to use
that nonaccrual-experience method in that
taxable year; and
(C) The taxpayer must change to (or
adopt) for that taxable year either—
(1) Another nonaccrual-experience
method that clearly reflects experience,
that is, a nonaccrual-experience method
that meets the first-year self-test require-
ment; or
(2) A safe harbor nonaccrual-experi-
ence method described in paragraphs (f)(1)
through (f)(5) of this section.
(iii)Three-year self-test—(A)In gen-
eral. The three-year self-test must be per-
formed by comparing the sum of the un-
collectible amounts for the current taxable
year and prior two taxable years (cumu-
lative uncollectible amount) with the sum
of the taxpayer’s actual experience for the
current taxable year and prior two tax-
able years (cumulative actual experience
amount).
(B)Recapture. If the cumulative un-
collectible amount for the test period is
greater than the cumulative actual ex-
perience amount for the test period, the
taxpayer’s uncollectible amount is lim-
ited to the cumulative actual experience
amount for the test period. Any excess
of the taxpayer’s cumulative uncollectible
amount over the taxpayer’s cumulative
actual nonaccrual-experience amount ex-
2006–41 I.R.B.666October 10, 2006

cluded from income during the test period
must be recaptured into income in the third
taxable year of the three-year self-test pe-
riod.
(C)Determination of whether method
is permissible or impermissible.Ifthe
cumulative uncollectible amount is less
than 110 percent of the cumulative ac-
tual experience amount, the taxpayer’s
nonaccrual-experience method is treated
as a permissible method and the tax-
payer may continue to use its alternative
nonaccrual-experience method, subject
to the three-year self-test requirement
of this paragraph (e)(2)(iii). If the cu-
mulative uncollectible amount is greater
than or equal to 110 percent of the cu-
mulative actual experience amount, the
taxpayer’s nonaccrual-experience method
is treated as impermissible in the taxable
year subsequent to the three-year self-test
year and does not clearly reflect its ex-
perience. The taxpayer must change to
another nonaccrual-experience method
that clearly reflects experience, includ-
ing, for example, one of the safe harbor
nonaccrual-experience methods described
in paragraphs (f)(1) through (f)(5) of
this section, for the subsequent taxable
year. A change in method of accounting
from an impermissible method under this
paragraph (e)(2)(iii)(C) to a permissible
method in the taxable year subsequent to
the three-year self-test year is made on a
cut-off basis.
(iv)Determination of taxpayer’s actual
experience. Reserved.
(3)Safe harbor comparison
method—(i)In general. A taxpayer
using, or desiring to use, a nonaccrual-ex-
perience method under the safe harbor
in paragraph (f)(5) of this section must
self-test its nonaccrual-experience method
for its first taxable year for which the
taxpayer uses, or desires to use, that
nonaccrual-experience method (first-year
self-test) and every three taxable years
thereafter (three-year self-test). A nonac-
crual-experience method under the safe
harbor in paragraph (f)(5) of this section
is deemed to clearly reflect experience
provided all the requirements of the
safe harbor comparison method of this
paragraph (e)(3) aremet. Each self-test
must be performed by comparing the un-
collectible amount (under the taxpayer’s
nonaccrual-experience method) with the
uncollectible amount that would have
resulted from use of one of the safe harbor
methods described in paragraph (f)(1),
(f)(2), (f)(3), or (f)(4) of this section.
A change from a nonaccrual-experi-
ence method that uses the safe harbor
comparison method for self-testing to
a nonaccrual-experience method that
does not use the safe harbor comparison
method for self-testing, and vice versa,
is a change in method of accounting to
which the provisions of sections 446
and 481 and the regulations apply. A
change solely to use or discontinue use
of the safe harbor comparison method
for purposes of determining whether the
nonaccrual-experience method clearly
reflects experience must be made on a
cut-off basis and without audit protection.
(ii)Requirements to use safe har-
bor comparison method—(A)First-year
self-test. The first-year self-test must be
performed by comparing the uncollectible
amount with the uncollectible amount
determined under any of the safe harbor
methods described in paragraph (f)(1),
(f)(2), (f)(3), or (f)(4) of this section (safe
harbor uncollectible amount) for its first
taxable year for which the taxpayer uses, or
desires to use, that nonaccrual-experience
method. If the uncollectible amount for
the first-year self-test is less than or equal
to the safe harbor uncollectible amount,
then the taxpayer’s nonaccrual-experience
method is treated as clearly reflecting its
experience for the first taxable year. If,
as a result of the first-year self-test, the
uncollectible amount for the test period is
greater than the safe harbor uncollectible
amount, then—
(1) The taxpayer’s nonaccrual-experi-
ence method is treated as not clearly re-
flecting its experience;
(2) The taxpayer is not permitted to use
that nonaccrual-experience method in that
taxable year; and
(3) The taxpayer must change to (or
adopt) for that taxable year either—
(i) Another nonaccrual-experience
method that clearly reflects experience,
that is, a nonaccrual-experience method
that meets the first-year self-test require-
ment; or
(ii) A safe harbor nonaccrual-experi-
ence method described in paragraphs (f)(1)
through (f)(5) of this section.
(B)Three-year self-test. The three-year
self-test must be performed by compar-
ing the sum of the uncollectible amounts
for the current taxable year and prior two
taxable years (cumulative uncollectible
amount) with the sum of the uncollectible
amount determined under any of the safe
harbor methods described in paragraph
(f)(1), (f)(2), (f)(3), or (f)(4) of this sec-
tion for the current taxable year and prior
two taxable years (cumulative safe harbor
uncollectible amounts). If the cumulative
uncollectible amountfor the three-year
self-test is less than or equal to the cu-
mulative safe harbor uncollectible amount
for the test period, then the taxpayer’s
nonaccrual-experience method is treated
as clearly reflecting its experience for the
test period and the taxpayer may continue
to use that nonaccrual-experience method,
subject to a requirement to self-test again
after three taxable years. If the cumulative
uncollectible amount for the test period is
greater than the cumulative safe harbor un-
collectible amount for the test period, the
taxpayer’s uncollectible amount is limited
to the cumulative safe harbor uncollectible
amount for the test period. Any excess
of the taxpayer’s cumulative uncollectible
amount over the taxpayer’s cumulative
safe harbor uncollectible amount excluded
from income during the test period must
be recaptured into income in the third tax-
able year of the three-year self-test period.
If the cumulative uncollectible amount
is less than 110 percent of the cumula-
tive safe harbor uncollectible amount, the
taxpayer’s nonaccrual-experience method
is treated as a permissible method and
the taxpayer may continue to use its al-
ternative nonaccrual-experience method,
subject to the three-year self-test require-
ment of this paragraph (e)(3)(ii)(B). If the
cumulative uncollectible amount is greater
than or equal to 110 percent of the cumula-
tive safe harbor uncollectible amount, the
taxpayer’s nonaccrual-experience method
is treated as impermissible in the taxable
year subsequent to the three-year self-test
year and does not clearly reflect its ex-
perience. The taxpayer must change to
another nonaccrual-experience method
that clearly reflects experience, includ-
ing, for example, one of the safe harbor
nonaccrual-experience methods described
in paragraphs (f)(1) through (f)(5) of
this section, for the subsequent taxable
year. A change in method of accounting
from an impermissible method under this
paragraph (e)(3)(ii)(B) to a permissible
method in the taxable year subsequent to
October 10, 20066672006–41 I.R.B.

the three-year self-test year is made on a
cut-off basis.
(4)Methods that do not clearly reflect
experience. [Reserved.]
(5)Contemporaneous documentation.
For purposes of this paragraph (e), includ-
ing the safe harbor comparison method of
paragraph (e)(3) of this section, a taxpayer
must document in its books and records, in
the taxable year any first-year or three-year
self-test is performed, the method used to
conduct the self-test, including appro-
priate documentation and computations
that resulted in the determination that the
taxpayer’s nonaccrual-experience method
clearly reflected the taxpayer’s nonac-
crual-experience for the applicable test
period.
(f)Safe harbors—(1)Safe harbor 1:
revenue-based moving average method.
A taxpayer may use a nonaccrual-expe-
rience method under which the taxpayer
determines the uncollectible amount by
multiplying its accounts receivable bal-
ance at the end of the current taxable year
by a percentage (revenue-based moving
average percentage). The revenue-based
moving average percentage is computed
by dividing the total bad debts sustained,
adjusted by recoveries received, through-
out the applicable period by the total
revenue resulting in accounts receivable
earned throughout the applicable period.
See paragraph (g)Example 4of this sec-
tion for an example of this method. Thus,
the uncollectible amount under the rev-
enue-based moving average method is
computed:
Bad debts sustained, adjusted byrecoveries received, during the
applicable period
Total revenue resulting in accounts receivable during the

(2)Safe harbor 2: actual experience
method—(i)Option A: single determina-
tion date. A taxpayer may use a nonac-
crual-experience method under which
the taxpayer determines the uncollectible
amount by multiplying its accounts re-
ceivable balance at the end of the current
taxable year by a percentage (moving av-
erage nonaccrual-experience percentage)
andthenincreasingtheresultingamount
by 5 percent. See paragraph (g)Example
5of this section for an example of safe
harbor 2 in general, and paragraph (g)
Example 6of this section for an example
of the single determination date option
of safe harbor 2. The taxpayer’s moving
average nonaccrual-experience percent-
age is computed by dividing the total bad
debts sustained, adjusted by recoveries
that are allocable to the bad debts, by the
determination date of the current taxable
year related to the taxpayer’s accounts re-
ceivable balance at the beginning of each
taxable year during the applicable period
by the sum of the accounts receivable at
the beginning of the each taxable year
during the applicable period. Thus, the
uncollectible amount under Option A of
the actual experiencemethod is computed:
Bad debts sustained, adjusted by recoveries received
that are allocable to the bad debts, by the determination
date of the current taxable year related to the taxpayer’s
accounts receivable balance at the beginning of each
taxable year during the applicable period
Sum of accounts receivable at the beginning of each
taxable year during the applicable period
×
Accounts receivable at end
of current taxable year
×1.05
(ii)Option B: multiple determination
dates. Alternatively, in computing its bad
debts related to the taxpayer’s accounts re-
ceivable balance at the beginning of each
taxable year during the applicable period,
a taxpayer may use the original determina-
tion date for each taxable year during the
applicable period. That is, the taxpayer
may use bad debts sustained, adjusted by
recoveries received that are allocable to
the bad debts, by the determination date of
each taxable year during the applicable pe-
riod rather than the determination date of
the current taxable year. See paragraph (g)
Example 7of this section for an example
of the multiple determination date option
of safe harbor 2. Thus, the uncollectible
amount under Option B of the actual expe-
rience method is computed:
Sum of, for each taxable year during the applicable
period, bad debts sustained, adjusted by recoveries
received that are allocable to the bad debts, by that
taxable year’s determination date and related to the
taxpayer’s accounts receivable balance at the beginning
of the taxable year
Sum of accounts receivable at the beginning of each
taxable year during the applicable period

Accounts receivable at end
of current taxable year

(iii)Tracing of recoveries—(A)In gen-
eral. Bad debts related to the taxpayer’s
accounts receivable balance at the begin-
ning of each taxable year during the appli-
cable period must be adjusted by the por-
tion, if any, of recoveries received that are
properly allocable to the bad debts.
(B)Specific tracing. If a taxpayer, with-
out undue burden, can trace all recoveries
to their corresponding charge-offs, the tax-
payer must specifically trace all recover-
ies.
(C)Recoveries cannot be traced with-
out undue burden. If a taxpayer has any
recoveries that cannot, without undue bur-
den, be traced to corresponding charge-
offs, the taxpayer may allocate those or all
recoveries between charge-offs of amounts
in the relevant beginning accounts receiv-
able balances and other charge-offs using
an allocation method that is reasonable un-
der all of the facts and circumstances.
(1)Reasonable allocations. An allo-
cation method is reasonable if there is a
cause and effect relationship between the
allocation base or ratio and the recoveries.
A taxpayer may elect to trace recoveries
that are traceable and allocate all untrace-
able recoveries to charge-offs of amounts
in the relevant beginning accounts receiv-
able balances. Such an allocation method
will be deemed to be reasonable under all
the facts and circumstances.
(2)Allocations that are not reasonable.
Allocation methods that generally will not
be considered reasonable include, for ex-
ample, methods in which there is not a
cause and effect relationship between the
allocation base or ratio and methods in
which receivables for which the nonac-
crual-experience method is not allowed to
be used are included in the allocation. See
paragraph (c)(1)(ii) of this section for ex-
amples of receivables for which the nonac-
crual-experience method is not allowed.
(3)Safe harbor 3: modified Black Mo-
tor method. A taxpayer may use a nonac-
crual-experience method under which
the taxpayer determines the uncollectible
amount by multiplying its accounts re-
ceivable balance at the end of the current
taxable year by a percentage (modified
Black Motor moving average percentage)
and then reducing the resulting amount
by the bad debts written off during the
current taxable year relating to accounts
receivable generated during the current
taxable year. The modified Black Motor
moving average percentage is computed
by dividing the total bad debts sustained,
adjusted by recoveriesreceived, during the
applicable period by the sum of accounts
receivable at the end of each taxable year
during the applicable period. See para-
graph (g)Example 8of this section for an
example of this method. Thus, the uncol-
lectible amount under the modified Black
Motor method is computed:
Bad debts sustained, adjusted by
recoveries received, during the
applicable period
Sum of accounts receivable at the
end of each taxable year during the
applicable period
×
Accounts receivable at end of
current taxable year
Bad debts written off during the
current taxable year relating to
accounts receivable generated during
the current taxable year
(4)Safe harbor 4: modified moving
average method. A taxpayer may use
a nonaccrual-experience method under
which the taxpayer determines the un-
collectible amount by multiplying its
accounts receivable balance at the end of
the current taxable year by a percentage
(modified moving average percentage).
The modified moving average percentage
is computed by dividing the total bad debts
sustained, adjusted by recoveries received,
during the applicable period other than bad
debts that were written off in the same tax-
able year the relatedaccounts receivable
were generated by the sum of accounts
receivable at the beginning of each taxable
year during the applicable period. See
paragraph (g)Example 9of this section
for an example of this method. Thus, the
uncollectible amount under the modified
moving average method is computed:
(Bad debts sustained, adjusted by recoveries received, during
the applicable period
Bad debts written off in same taxable
year accounts receivable generated)
Sum of accounts receivable at the beginning of each taxable
year during the applicable period
× Accounts receivable at end of current taxable year
(
5)Safe harbor 5: alternative nonac-
c
rual-experience method. A taxpayer may
use an alternative nonaccrual-experience
method that clearly reflects the taxpayer’s
actual nonaccrual-experience, provided
the taxpayer’s alternative nonaccrual-ex-
perience method meets the self-test re-
quirements described in paragraph (e)(3)
of this section.
(
g)Examples. The following examples
i
llustrate the provisions of this section. In
each example, the taxpayer uses a calendar
year for Federal income tax purposes and
an accrual method of accounting, does not
require the payment of interest or penalties
with respect to past due accounts receiv-
able (except in the case ofExample 3) and,
in the case ofExamples 5through7, selects
a
n appropriate determination date for each
t
axable year. The examples are as follows:
Example 1.Contractual allowance or adjust-
ment. B, a healthcare provider, performs a medical
procedure on individual C, who has health insurance
coverage with IC, an insurance company. B bills IC
and C for $5,000, B’s standard charge for this med-
ical procedure. However, B has a contract with IC
that obligates B to accept $3,500 as full payment for
the medical procedure if the procedure is provided
to a patient insured by IC. Under the contract, only
$3,500 of the $5,000 billed by B is legally collectible
October 10, 20066692006–41 I.R.B.

from IC and C. The remaining $1,500 represents
a contractual allowance or contractual adjustment.
Under paragraph (c)(1)(i) of this section, the remain-
ing $1,500 is not a contractually collectible amount
for purposes of this section and B may not use a
nonaccrual-experience method with respect to this
portion of the receivable.
Example 2.Charitable or pro bono services.D,
a law firm, agrees to represent individual E in a le-
gal matter and to provide services to E on a pro bono
basis. D normally charges $500 for these services.
Because D provides its services to E pro bono, D’s
services are never billed or intended to result in rev-
enue. Thus, under paragraph (c)(1)(i) of this section,
the $500 is not a collectible amount for purposes of
this section and D may not use a nonaccrual-experi-
ence method with respect to this portion of the receiv-
able.
Example 3.Charging interest and/or penalties.
Z has two billing methods for the amounts to be re-
ceived from Z’s provision of services described in
paragraph (a)(1) of this section. Under one method,
for amounts that are more than 90 days past due, Z
charges interest at a market rate until the amounts
(together with interest) are paid. Under the other
billing method, Z charges no interest for amounts past
due. Under paragraph (c)(1)(ii) of this section, A may
not use a nonaccrual-experience method of account-
ing with respect to any of the amounts billed under
the method that charges interest on amounts that are
more than 90 days past due. Z may, however, use
the nonaccrual-experience method with respect to the
amounts billed under the method that does not charge
interest for amounts past due.
Example 4.Safe harbor 1: Revenue-based mov-
ing average method. (i) F uses the revenue-based
moving average method described in paragraph (f)(1)
of this section with an applicable period of six tax-
able years. F’s total accounts receivable and bad debt
experience for the 2006 taxable year and the five im-
mediately preceding consecutive taxable years are as
follows:

Total
$330,000$64,900
(ii) F’s revenue-based moving average percent-
age is 19.67% ($64,900/$330,000). If $49,300 of
accounts receivable remains outstanding as of the
close of that taxable year(2006), F’s uncollectible
amount using the revenue-based moving average safe
harbor method is computed by multiplying $49,300
by the revenue-based moving average percentage
of 19.67%, or $9,697. Thus, F may exclude $9,697
from gross income for 2006.
Example 5.Safe harbor 2: Actual experience
method. (i) G is eligible to use a nonaccrual-expe-
rience method and wishes to adopt the actual expe-
rience method of paragraph (f)(2) of this section. G
elects to use a three-year applicable period consisting
of the current and two immediately preceding consec-
utive taxable years. G determines that its actual ac-
counts receivable collection experience is as follows:

Total
$3,735,000$175,000
(ii) G’s ending A/R Balance on December 31,
20
08, is $880,000. In 2008, G computes its uncol-
lectible amount by using a three-year moving average
under paragraph (f)(2) of this section. G’s moving av-
er
age nonaccrual-experience percentage is 4.7%, de-
termined by dividing the sum of the amount of G’s ac-
counts receivable outstanding on January 1 of 2006,
2
007, and 2008, that were determined to be bad debts
(adjusted for recoveries allocable to the bad debts)
on or before the corresponding determination date(s),
b
y the sum of the amount of G’s accounts receivable
outstanding on January 1 of 2006, 2007, and 2008
($175,000/$3,735,000 or 4.7%). G’s uncollectible
amount for 2008 is determined by multiplying this
percentage by the balanceof G’s accounts receivable
on December 31, 2008 ($880,000 x 4.7% =$41,360),
and increasing this amount by 105% ($41,360 x 105%
= $43,428). G may exclude $43,428 from gross in-
come for 2008.
Example 6.Safe harbor 2: Single determination
date (Option A). H is eligible to use a nonaccrual-ex-
perience method and wishes to adopt the actual expe-
rience method of paragraph (f)(2) of this section. H
elects to use a six-year applicable period consisting
of the current and five immediately preceding taxable
ye
ars. H also elects to use a single determination date
in accordance with paragraph (f)(2)(i) of this section.
H selects December 31, its taxable year-end, as its
de
termination date. Since H is using a single deter-
mination date from the current taxable year, its deter-
mination date for the 2001–2006 applicable period is
D
ecember 31, 2006. H has a $800 charge-off in 2003
of an account receivable in the 2003 beginning ac-
counts receivable balance. In 2005, H has a recovery
o
f $100 which is traceable, without undue burden, to
the $800 charge-off in 2003. Since the $100 recovery
occurred prior to H’s December 31, 2006, determina-
tion date, it reduces the amount of H’s bad debts in the
numerator of the formula for purposes of determining
H’s moving average nonaccrual-experience percent-
age. In addition, H must include the $100 recovery in
income in 2005 (see paragraph (d)(5) of this section
regarding recoveries).
Example 7.Safe harbor 2: Multiple determina-
tion dates (Option B).Thefactsarethesameasin
Example 6, except H elects to use multiple determi-
nation dates in accordance with paragraph (f)(2)(ii) of
this section. Consequently, H’s determination date is
December 31, 2001, for its calculations of the portion
of
the numerator relating to the 2001 taxable year, De-
cember 31, 2002, for its calculations of the portion of
the numerator relating to the 2002 taxable year, and
so
on through the final taxable year (2006), which has
a determination date of December 31, 2006. Since
the $100 recovery did not occur until after Decem-
b
er 31, 2003 (the determination date for the 2003 tax-
able year), it does not reduce the amount of H’s bad
debts in the numerator of the formula for purposes
o
f determining H’s moving average nonaccrual-ex-
perience percentage. However, H still must include
the $100 recovery in income in 2005 (see paragraph
(d)(5) of this section regarding recoveries).
Example 8.Safe harbor 3: Modified Black Motor
method. (i) J uses the modified Black Motor method
described in paragraph (f)(3) of this section and a six-
year applicable period. J’s total accounts receivable
and bad debt experience for the 2006 taxable year and
the five immediately preceding consecutive taxable
years are as follows:

(ii) J’s modified Black Motor moving average
percentage is 8.228% ($75,700/$920,000). If the
accounts receivable generated and written off during
the current taxable year are $3,600, J’s uncollectible
amount is $11,210, computed by multiplying J’s ac-
counts receivable on December 31, 2006 ($180,000)
by the modified Black Motor moving average per-
centage of 8.228% and reducing the resulting amount
by $3,600 (J’s accounts receivable generated and
written off during the 2006 taxable year). J may
exclude $11,210 from gross income for 2006.
Example 9.Safe harbor 4: Modified moving av-
erage method. (i) The facts are the same as inEx-
ample 8, except that the balances represent accounts
receivable at the beginning of the taxable year, and J
uses the modified moving average method described
inparagraph(f)(4)ofthis section and a six-year ap-
plicable period. Furthermore, the accounts receivable
that were written off in the same taxable year they
were generated, adjusted for recoveries of bad debts
during the period are as follows:

tiplying J’s accounts receivable on December 31,
2006 ($180,000) by the modified moving average
pe

gross income for 2006.
Example 10.First-year self-test. Beginning in
20
06, K is eligible to use a nonaccrual-experience
method and wants to adopt an alternative nonaccrual-
experience method under paragraph (f)(5) of this sec-
ti
on, and consequently is subject to the safe harbor
comparison method of self-testing under paragraph
(e)(3) of this section. K elects to self-test against safe
h
arbor 1 for purposes of conducting its first-year self-
test. K’s uncollectible amount for 2006 is $22,000.
K’s safe harbor uncollectible amount under safe har-
b
or 1 is $21,000. Because K’s uncollectible amount
for 2006 ($22,000) is greater than the safe harbor un-
collectible amount ($21,000), K’s alternative nonac-
crual-experience method is treated as not clearly re-
flecting its nonaccrual experience for 2006. Accord-
ingly, K must adopt either another nonaccrual-experi-
ence method that clearly reflects experience (subject
to the self-testing requirements of paragraph (e)(2)(ii)
of this section, or a safe harbor nonaccrual-experience
method described in paragraph (f)(1) (revenue-based
moving average), (f)(2) (actual experience method),
(f)(3) (modified Black Motor method), (f)(4) (modi-
fied moving average method) of this section, or an-
other alternative nonaccrual-experience method un-
der paragraph (f)(5) of this section that meets the
self-testing requirements of paragraph (e)(3) of this
section.
Example 11.Three-year self-test. The facts are
thesameasinExample 10,exceptthatK’ssafe
har
bor uncollectible amount under safe harbor 1
for 2006 is also $22,000. Consequently, K meets
the first-year self-test requirement and may use its
al
ternative nonaccrual-experience method. Subse-
quently, K’s cumulative uncollectible amount for
2007 through 2009 is $300,000. K’s safe harbor
un
collectible amount for 2007 through 2009 under
its chosen safe harbor method for self-testing (safe
harbor 1) is $295,000. Because K’s cumulative
u
ncollectible amount for the three-year test period
(taxable years 2007 through 2009) is greater than its
safe harbor uncollectible amount for the three-year
t
est period ($295,000), under paragraph (e)(3)(ii)(B)
of this section, the $5,000 excess of K’s cumulative
uncollectible amount over K’s safe harbor uncol-
lectible amount for the three-year test period must be
recaptured into income in 2009 in accordance with
paragraph (e)(3)(ii)(B) of this section. Since K’s
cumulative uncollectible amount for the three-year
test period ($300,000) is less than 110% of its safe
harbor uncollectible amount ($295,000 x 110% =
$324,500), under paragraph (e)(3)(ii)(B) of this
section, K may continue to use its alternative nonac-
crual-experience method, subject to the three-year
self-test requirement.
Example 12.Subsequent worthlessness of year-
end receivable. The facts are the same as inExam-
ple 4, except that one of the accounts receivable out-
standing at the end of 2002 was for $8,000, and in
2003, under section 166, the entire amount of this re-
ceivable becomes wholly worthless. Because F does
not accrue as income $1,573 of this account receiv-
able ($8,000 x .1967) under the nonaccrual-experi-
ence method in 2002, under paragraph (d)(2) of this
sec
tion F may not deduct this portion of the account
receivable as a bad debt deduction under section 166
in 2003. F may deduct the remaining balance of the
re
ceivable in 2003 as a bad debt deduction under sec-
tion 166 ($8,000 - $1,574 = $6,426).
Example 13.Subsequent collection of year-end
re
ceivable. The facts are the same as inExample 4.
In 2007, F collects in full an account receivable of
$1,700 that was outstanding at the end of 2006. Under
pa
ragraph (d)(5) of this section, F must recognize ad-
ditional gross income in 2007 equal to the portion of
this receivable that F excluded from gross income in
t
he prior taxable year ($1,700 x .1967 = $334). That
amount ($334) is a recovery under paragraph (d)(5)
of this section.

at least 60,000 of the manufacturer’s pas-
senger automobiles and light trucks that
qualify for either credit have been sold for
use or lease in the United States (deter-
mined on a cumulative basis for sales after
December 31, 2005). Taxpayers purchas-
ing the manufacturer’s vehicles during the
first two calendar quarters of the phase-out
period may claim only 50 percent of the
otherwise allowable credit. Taxpayers pur-
chasing the manufacturer’s vehicles dur-
ing the third and fourth quarters of the

Guidance on the Application of
Section 911 to U.S. Individuals
Working at Guantanamo Bay
Notice 2006–84
This notice provides guidance regard-
ing the application of section 911 of the In-
ternal Revenue Code to U.S. citizens and
residents earning income from performing
services at the U.S. Naval Base at Guan-
tanamo Bay.
Section 911(a) of the Code allows a
qualified individual to elect to exclude
from gross income his or her foreign
earned income (as defined in section
911(b)) and housing cost amount. Section
911(d)(1) generally defines a “qualified
individual” as a U.S. citizen or resident
whose tax home is in a foreign country
and who meets certain requirements of
residence or presence in a foreign coun-
try. Section 1.911–3(a) of the Income
Tax Regulations defines foreign earned
income as earned income from sources
within a foreign country (as defined in
section 1.911–2(h) of the regulations)
that is earned during a period for which
the individual qualifies under section
1.911–2(a) to make an election. Earned
income is from sources within a foreign
country if it is attributable to services
performed by an individual in a foreign
country or countries. Section 1.911–2(h)
provides, in part, that the term “foreign
country” when used in a geographical
sense includes any territory under the sov-
ereignty of a government other than that
of the United States. Section 911(b)(1)(B)
excludes from the definition of foreign
earned income certain amounts, includ-
ing amounts paid by the United States or
an agency thereof to an employee of the
United States or an agency thereof.
Section 911(d)(8)(A) of the Code pro-
vides, generally, that if travel (or any
transaction in connection with such travel)
with respect to any foreign country is pro-
scribed by certain regulations during any
period, then: (1) foreign earned income
does not include income from sources
within that country attributable to services
performed during that period; (2) housing
expenses do not include any expenses al-
locable to such period for housing in that
country, or for housing of the taxpayer’s
spouse or dependents in another country
while the taxpayer is present in that coun-
try; and (3) an individual is not treated as
abona fideresident of, or as present in, a
foreign country for any day during which
the individual was present in that country
during that period. The regulations iden-
tified in section 911(d)(8)(A) are those
promulgated pursuant to the Trading With
the Enemy Act (“TWEA”), 50 U.S.C.
App. 1et seq., or the International Emer-
gency Economic Powers Act, 50 U.S.C.
1701et seq., that include provisions gener-
ally prohibiting U.S. citizens and residents
from engaging in transactions related to
travel to, from, or within certain foreign
countries. Section 911(d)(8)(B). Section
911(d)(8)(C), however, provides that the
limitations of section 911(d)(8)(A) do not
apply to any individual during any period
in which such individual’s activities are
not in violation of these regulations.
In 1963, the Department of the Trea-
sury’s Office of Foreign Assets Control
(“OFAC”) issued the Cuban Assets Con-
trol Regulations (the “CACR”), 31 C.F.R.
part 515. The CACR were issued pursuant
to TWEA. Section 515.201(b)(1) of the
CACR prohibits persons subject to United
States jurisdiction from all dealings in
any property in which Cuba or a Cuban
national has or has had an interest since
July 8, 1963, unless authorized by OFAC.
OFAC interprets this prohibition to include
a prohibition on all transactions related to
travel to, from, and within Cuba.See, e.g.,
§ 515.560 of the CACR, which authorizes
certain transactions related to travel to,
from, and within Cuba for participation in
certain activities.
Section 911(d)(8) of the Code was en-
acted as part of the Tax Reform Act of 1986
(Pub. L. No. 99–514, 1986–3 C.B. 1, 481).
The Report of the Senate Committee on Fi-
nance (S. Rep. No. 99–313, 99
th
Cong.,
2d Sess. 389 (1986)) listed Cuba as one
of the countries for which Treasury reg-
ulations proscribed transactions related to
travel of U.S. citizens and residents. Sec-
tion 911(d)(8) continues to apply to Cuba.
See, Rev. Rul. 2005–3, 2005–1 C.B. 334.
After consultations with OFAC, the IRS
and Treasury have determined that for pur-
poses of section 911(d)(8) of the Code, the
CACR do not proscribe transactions re-
lated to travel, to, from, or within the U.S.
Naval Base at Guantanamo Bay. For pur-
poses of determining whether an individ-
ual’s earned income is from sources within
a foreign country for the purpose of sec-
tion 911(b) and section 1.911–3(a) of the
regulations, however, the individual who
is performing services at the U.S. Naval
Base at Guantanamo Bay is performing
services within a foreign country. See sec-
tion 1.911–2(h).
Accordingly, under section 911(d)
(8)(C) of the Code, the limitations of sec-
tion 911(d)(8)(A) do not apply to qualified
individuals who are performing services at
the U.S. Naval Base at Guantanamo Bay.
Therefore, such individuals are eligible for
the exclusion under section 911 provided
that they meet the other requirements of
that section.

Chief Counsel (International). For further

Treatment Under Section
367(b) of Property Used
to Purchase Parent Stock
in Certain Triangular
Reorganizations
Notice 2006–85
SECTION 1. OVERVIEW
This notice announces that the Internal
Revenue Service (IRS) and the Treasury
Department (Treasury) will issue regula-
tions under section 367(b) of the Internal
Revenue Code that address certain triangu-
lar reorganizations under section 368(a) in-
volving one or more foreign corporations.
This notice is issued in response to com-
ments and specific requests for guidance
regarding certain transactions that are de-
signed to avoid U.S. income tax, includ-
ing tax on the repatriation of a subsidiary’s
earnings. The transactions generally in-
volve a subsidiary purchasing its parent’s
stock for property and then transferring the
stock in exchange for the stock or assets
of a corporation in a triangular reorganiza-
tion under section 368(a). In general, and
as described below, the regulations issued
pursuant to this notice will apply to trans-
actions occurring on or after September 22,
2006.
The IRS and Treasury recently finalized
§1.367(b)–4(b)(1)(ii), which may apply to
October 10, 20066772006–41 I.R.B.

certain (but not all) of the triangular reor-
ganizations described in this notice. That
final regulation under section 367(b) ap-
propriately addressed the treatment of the
majority of relevant triangular reorganiza-
tions. While the IRS and Treasury were
aware of the transactions covered by this
notice at that time, the decision was made
to address these transactions comprehen-
sively in separate guidance.
The following definitions apply for pur-
poses of this notice. A “triangular reorga-
nization” is a forward triangular merger,
a triangular C reorganization, a reverse
triangular merger, or a triangular B re-
organization, as those terms are defined
in §1.358–6(b)(2)(i) through (iv), respec-
tively, or a reorganization described in sec-
tion 368(a)(1)(G) and (a)(2)(D). In addi-
tion, P, S, and T are corporations described
in §1.358–6(b)(1)(i) through (iii), respec-
tively. Finally, the term “property” means
money, securities, and any other property,
except that the term does not include stock
in S.
SECTION 2. TRANSACTIONS AT
ISSUE
The IRS and Treasury are aware that
certain taxpayers are engaging in triangu-
lar reorganizations involving foreign cor-
porations that result in a tax-advantaged
transfer of property from S to P. The trans-
action is often structured as a triangular
B reorganization, but could also be struc-
tured as a triangular C reorganization or
another type of triangular reorganization.
For example, assume P, a domestic corpo-
ration, owns 100 percent of S, a foreign
corporation, and S1, a domestic corpora-
tion. S1 owns 100 percent of T, a foreign
corporation. S purchases P stock for either
cash or a note, and provides the P stock to
S1 in exchange for all the T stock in a tri-
angular B reorganization.
Taxpayers take the position that (i)
when P sells its stock to S for cash or
a note, P recognizes no gain or loss on
the sale under section 1032, (ii) S takes
a cost basis in the P shares under section
1012, and (iii) S recognizes no gain under
§1.1032–2(c) upon the transfer of the P
shares immediately thereafter because the
basis and fair market value of the shares
are equal. Thus, taxpayers take the po-
sitionthatthecashornoteusedbySto
acquire the P stock does not result in a
distribution under section 301. Further-
more, taxpayers do not include in income
amounts under section 951(a)(1)(B) be-
cause S acquires and disposes of the P
stock before the close of a quarter of
the taxable year, which is the time at
which to measure P’s share of the average
amount of United States property held
by S.Seesection 956(a)(1)(A). Finally,
under §1.367(b)–4(b)(1)(ii), S1 does not
include in income as a deemed dividend
the section 1248 amount attributable to the
T stock that S1 exchanges.
The IRS and Treasury believe that the
taxpayers’ characterization of these trans-
actions raises significant policy concerns,
particularly when either P or S (or both)
is a foreign corporation (regardless of
whetherTisrelatedtoPandSbefore
the transaction). For example, when P is
domestic and S is foreign, as in the exam-
ple described above, the transaction could
have the effect of repatriating foreign
earnings of S to P without a corresponding
dividend to P that would be subject to U.S.
income tax. Similarly, where P is foreign
and S is domestic, the transaction could
have the effect of repatriating S’s U.S.
earnings to its foreign parent in a manner
that is not subject to U.S. withholding
tax. This variation of the transaction also
raises U.S. earnings stripping issues where
S uses a note to purchase all or a portion
of the P stock. Moreover, where both P
and S are foreign, the transactions may
have the effect of avoiding income in-
clusions to certain U.S. shareholders of
P that would be subject to U.S. income
tax under the subpart F provisions, absent
the application of an exception, such as
under section 954(c)(6). In addition, for-
eign-to-foreign transactions of this type
can be used to facilitate the subsequent
repatriation of foreign earnings to U.S.
shareholders without U.S. income tax.
SECTION 3. BACKGROUND
.01 Triangular reorganizations
Section 368 defines the term “re-
organization.” Sections 368(a)(1)(B),
368(a)(1)(C), 368(a)(1)(G), 368(a)(2)(D),
and 368(a)(2)(E) describe certain reorga-
nizations in which P stock may be used by
S as the consideration issued in exchange
for T’s stock or assets, as applicable.
Section 1032 provides that no gain or
loss will be recognized to a corporation
on the receipt of money or other property
in exchange for stock of such corporation.
Section 1.1032–2(b) provides that in the
case of a forward triangular merger, a trian-
gular C reorganization, or a triangular B re-
organization, P stock provided by P to S, or
directly to T or T’s shareholders on behalf
of S, pursuant to the plan of reorganization
is treated as a disposition by P of shares
of its own stock. However, §1.1032–2(c)
provides that S must recognize gain or loss
in the above transactions on its exchange
of P stock for T stock or assets if S did not
receive the P stock from P pursuant to the
plan of reorganization. Section 361 pro-
vides that S does not recognize gain or loss
on the P stock that it exchanges for T stock
in a reverse triangular merger.
Section 361(a) provides that no gain
or loss shall be recognized by T if it ex-
changes property in pursuance of the plan
of reorganization solely for stock or secu-
rities in P. Section 361(c) provides that no
gain or loss shall be recognized to T on the
distribution to its shareholders of P stock
received from P in pursuance of the plan
of reorganization.
Section 354 provides that no gain or
loss shall be recognized by T sharehold-
ers if stock or securities in T are, in pur-
suance of the plan of reorganization, ex-
changed solely for stock or securities of P.
Section 356 applies to T shareholders in
cases where they receive other property in
addition to the property permitted to be re-
ceived under section 354.
Section 358 provides rules for deter-
mining the T shareholders’ bases in their P
stock following triangular reorganizations.
Sections 1.358–6 and 1.367(b)–13 provide
rules for determining P’s basis in its S or T
stock, as applicable. If P files a consoli-
datedreturnwithSorT,otherbasisrules
apply.SeeTreas. Reg. §1.1502–30 or
1.1502–31.
.02 Section 367
Section 367(a)(1) provides that if, in
connection with any exchange described
in section 332, 351, 354, 356, or 361, a
United States person transfers property to
a foreign corporation, such foreign corpo-
ration shall not, for purposes of determin-
ing the extent to which gain shall be recog-
nized on such transfer, be considered to be
2006–41 I.R.B.678October 10, 2006

a corporation. The Secretary has broad au-
thority under section 367(a)(2), (3), and (6)
to provide that section 367(a)(1) will not
apply to certain transfers described therein.
In the case of any exchange described
in section 332, 351, 354, 355, 356, or
361 in connection with which there is no
transfer of propertydescribed in section
367(a)(1), section 367(b)(1) provides that
a foreign corporation shall be considered
to be a corporation except to the extent pro-
vided in regulations prescribed by the Sec-
retary which are necessary or appropriate
to prevent the avoidance of Federal income
taxes.
Section 367(b)(2) provides that the
regulations prescribed pursuant to section
367(b)(1) shall include (but shall not be
limited to) regulations dealing with the
sale or exchange of stock or securities in
a foreign corporation by a United States
person, including regulations providing,
among other things, the circumstances
under which gain is recognized, amounts
are included in gross income as a divi-
dend, adjustments are made to earnings
and profits, or adjustments are made to
basis of stock or securities.
.03 Distributions of property
Section 301(c)(1) provides that a distri-
bution of property by a corporation to its
shareholder with respect to its stock is in-
cluded in the shareholder’s gross income
to the extent the distribution constitutes a
dividend under section 316. Section 316
defines a dividend as a distribution out of
a corporation’s current and accumulated
earnings and profits. To the extent the dis-
tribution is not a dividend, the shareholder
reduces basis in the distributing corpora-
tion’s stock, and any amount of the distri-
bution in excess of the shareholder’s ba-
sis is treated as gain from the sale or ex-
change of the corporation’s stock.Seesec-
tion 301(c)(2) and (3).
Certain transactions that are exchanges
in form can be treated as distributions for
tax purposes. Section 304 generally pro-
vides that when a shareholder transfers
stock of a controlled corporation to an-
other controlled corporation in exchange
for property, the two legs of the exchange
are bifurcated and the receipt of the prop-
erty by the shareholder is treated as a dis-
tribution. Section 304, by its terms, does
not apply to the transfer by a shareholder
of its own stock to a controlled corpora-
tion in exchange for property, even though
the economic effect of that transaction is
essentially identical.
Other transactions may result in
deemed distribution treatment in certain
circumstances. For example, a share-
holder that exchanges common stock of a
corporation for common stock and prop-
erty pursuant to a recapitalization will
be treated as receivinga distribution of
property with respect to its stock under
section 301 if in substance the distribution
is a separate transaction.SeeTreas. Reg.
§1.301–1(l);see also,Bazley v. Comm’r,
331 U.S. 737 (1947).
.04 Distributions involving foreign
corporations or foreign shareholders
The treatment of a distribution varies
depending upon whether the corporation
or shareholder is domestic or foreign. A
distribution from a foreign corporation to
a shareholder that is a U.S. person result-
ing in a dividend under sections 301(c)(1)
and 316, or gain from the sale or exchange
of property under section 301(c)(3), gen-
erally is subject to U.S. income tax, with
potential offset by foreign tax credits.
A distribution from a domestic corpo-
ration to a shareholder that is not a U.S.
person resulting in a dividend is generally
taxable under section 871 or 881 at a rate
of 30 percent, subject to reduction under
an applicable treaty, and the domestic cor-
poration is responsible for withholding tax
under section 1441 or 1442. To the ex-
tent such a distribution results in gain from
the sale or exchange of property to the for-
eign shareholder under section 301(c)(3),
such amounts are subject to U.S. income
tax under section 897(a) if the distributing
corporation had been a United States real
property holding corporation (as defined
in section 897(c)(2)) within the past five
years. In such a case, the gain is subject
to U.S. income tax as income effectively
connected with the conduct of a trade or
business within the United States.
Finally, a distribution from a foreign
corporation to a shareholder that is a con-
trolled foreign corporation, within the
meaning of section 957, resulting in a div-
idend or gain from the sale or exchange
of property to the foreign shareholder un-
der section 301(c)(3) may also be subject
to U.S. income tax. For example, such
amounts may constitute subpart F income
and therefore result in an income inclusion
under section 951(a)(1)(A) to U.S. share-
holders, within the meaning of section
951(b), of the controlled foreign corpo-
ration, subject to certain exceptions.See,
e.g., section 954(c)(6).
SECTION 4. APPLICATION OF
SECTION 367(b)
Congress enacted section 367(b) to en-
sure that international tax considerations
are adequately addressed when the sub-
chapter C provisions apply to certain non-
recognition exchanges involving foreign
corporations. This provision was neces-
sary because the subchapter C provisions
were enacted largely to address transac-
tions involving domestic corporations and
shareholders that are United States per-
sons. As a result, the subchapter C pro-
visions do not fully account for interna-
tional tax concerns that arise when the pro-
visions apply to transactions involving for-
eign corporations or shareholders that are
not U.S. persons.
In enacting section367(b), Congress
noted that “it is essential to protect against
tax avoidance in transfers to foreign cor-
porations and upon the repatriation of
previously untaxed foreign earnings....”
H.R. Rep. No. 658, 94th Cong., 1
st
Sess.
241 (1975). In addition,because determin-
ing the proper interaction of the Code’s
international and subchapter C provi-
sions is “necessarilyhighly technical,”
Congress granted the Secretary broad reg-
ulatory authority to provide the “necessary
or appropriate” rules to prevent the avoid-
ance of Federal income taxes, rather than
enacting a more comprehensive statutory
regime.Id.This broad grant of authority
has been exercised on numerous occasions
to address a wide range of international
policy concerns.See, e.g., Treas. Reg.
§§1.367(b)–4(b)(1) (preserving section
1248 amounts), (b)(2) (addressing traf-
ficking in foreign tax credits by use of
preferred stock), –5(b)(1)(ii) (ensuring
section 311(b) gain is recognized by a
domestic corporation when it distributes
stock of a controlled foreign corporation
to an individual distributee under section
355), and –7 (addressing the carryover
of tax attributes in a foreign-to-foreign
section 381 transaction).
October 10, 20066792006–41 I.R.B.

In a triangular reorganization, the ex-
change by the T shareholders of their T
stock for P stock is described in section
354 or 356. As a result, a triangular reorga-
nization involving a foreign corporation is
described in section 367(b) and, therefore,
may be subject to regulations issued un-
der the broad regulatory authority granted
therein. It is on this basis that regulations
will be issued to address the triangular re-
organizations covered by this notice.
SECTION 5. REGULATIONS TO BE
ISSUED UNDER SECTION 367(b)
The IRS and Treasury will issue regula-
tions under section 367(b) to address cer-
tain triangular reorganizations involving
foreign corporations. The regulations will
apply to triangular reorganizations where
P or S (or both) is foreign and, pursuant
to the reorganization, S acquires from P,
in exchange for property, all or a portion
of the P stock that is used to acquire the
stock or assets of T (T could be either re-
lated or unrelated to P and S before the
transaction). In such a case, the regula-
tions under section 367(b) will make ad-
justments with respect to P and S such that
the property transferred from S to P in ex-
change for P stock will have the effect of
a distribution of property from S to P un-
der section 301(c) that is treated as sepa-
rate from the transfer by P of the P stock
to S pursuant to the reorganization. The
adjustments will be made notwithstanding
the fact that section 1032 otherwise applies
to the reorganization.Therefore, the regu-
lations will require, as appropriate, an in-
clusion in P’s gross income as a dividend,
areductioninP’sbasisinitsSorTstock,
andtherecognitionofgainbyPfromthe
sale or exchange of property. The regula-
tions will also provide for appropriate cor-
responding adjustments to be made, such
as a reduction of S’s earnings and profits as
a result of the distribution (consistent with
the principles of section 312). The regula-
tions will also address similar transactions
in which S acquires the P stock used in
the reorganization from a related party that
purchased the P stock in a related transac-
tion.
SECTION 6. EFFECTIVE DATE
In general, the regulations to be issued
under section 367(b) that are described in
section5ofthisnoticewillapplytotrans-
actions occurring on or after September
22, 2006. The regulations described in
this notice will not, however, apply to a
transaction that was completed on or after
September 22, 2006, provided the transac-
tion was entered into pursuant to a written
agreement which was (subject to custom-
ary conditions) binding before September
22, 2006 and all times thereafter.
No inference is intended as to the treat-
ment of transactions described herein
under current law, and the IRS may, where
appropriate, challenge such transactions
under applicable provisions or judicial
doctrines.
SECTION 7. COMMENTS
The IRS and Treasury request com-
ments on the regulations to be issued
under this notice. Specifically, comments
are requested as to whether in certain cases
it is appropriate to provide an exception
from the treatment described in this notice.
In addition, comments are requested as to
the source and timing of the adjustments
to be made with respect to P and S under
the regulations to be issued.
The IRS and Treasury also request
comments regarding transactions that are
not described in section 5 of this notice.
For example, comments are requested on
transactions where S or P is foreign and S
purchases P stock from a person unrelated
to P (for example, from the public on the
open market), or where S acquires the P
stock in a transaction that is unrelated to
the triangular reorganization. Finally, the
IRS and Treasury request comments on
the treatment of transactions similar to
those described in this notice that do not
qualify as reorganizations (for example,
because S issues minimal consideration
to T in a transaction that would other-
wise qualify as a reorganization under
section 368(a)(1)(B)). Any regulations
issued to address transactions that are not
described in section 5 of this notice will
apply prospectively.

“Tie-breaking” Rule for Two or
More Taxpayers Claiming a
Child as a Qualifying Child
Notice 2006–86
PURPOSE
This notice provides interim guidance
under § 152(c)(4) of the Internal Revenue
Code, the rule for determining which tax-
payer may claim a qualifying child when
two or more taxpayers claim the same
child under any of the following provi-
sions: (1) head of household filing status
under § 2(b), (2) the child and dependent
care credit under § 21, (3) the child tax
credit under § 24, (4) the earned income
credit under § 32, (5) the exclusion for
dependent care assistance under § 129
(which incorporates by reference the def-
inition of qualifying child or other quali-
fying individual under § 21), and (6) the
dependency deduction under § 151. This
notice clarifies that,unless the special rule
in § 152(e) applies, the tie-breaking rule in
§ 152(c)(4) applies to these provisions as a
group, rather than on a section-by-section
basis.
Section 152 was amended by § 201 of
the Working Families Tax Relief Act of
2004 (WFTRA), Pub. L. No. 108–311,
118 Stat. 1169, effective for taxable years
beginning after December 31, 2004. The
Internal Revenue Service and Treasury
Department intend to issue regulations
consistent with the guidance contained in
this notice. The guidance in this notice ap-
plies until those regulations are effective.
BACKGROUND
Definition of a qualifying child
Section 151 allows a taxpayer a deduc-
tion of the exemption amount for each in-
dividual who is a dependent (as defined in
§ 152) of the taxpayer for the taxable year.
2006–41 I.R.B.680October 10, 2006

Under § 152(a), a dependent is a qualify-
ing child or qualifying relative.
Section 152(c)(1) defines a qualifying
child as an individual who (A) bears a
certain relationship to the taxpayer (child,
brother, sister, stepbrother, stepsister or de-
scendant of any of those relatives), (B) has
the same principal place of abode as the
taxpayer for more than one-half of the tax-
able year, (C) meets certain age require-
ments, and (D) does not provide over one-
half of the child’s own support for the cal-
endar year in which the taxable year of the
taxpayer begins.
WFTRA establishes a uniform defini-
tion of a qualifying child under § 152(c)
for determining whether a taxpayer qual-
ifies for head of household filing sta-
tus, the child and dependent care credit,
the child tax credit, the earned income
credit, and the dependency deduction.
See§§ 2(b)(1)(A)(i), 21(b)(1)(A), 24(c),
32(c)(3), and 151, respectively, and
H.R. Conf. Rep. No. 696, 108
th
Cong.,
2d Sess. 55–65 (2004). The uniform defi-
nition also applies in determining whether
a taxpayer qualifies for the income ex-
clusion under § 129, which defines de-
pendent care assistance by reference to
employment-related expenses (as defined
in § 21(b)(2)) for the care of a qualifying
child or other qualifying individual.
“Tie-breaking” rule
Section 152(c)(4) provides a tie-break-
ing rule for determining which taxpayer
may claim a qualifying child as a quali-
fying child when two or more taxpayers
claim the same child for a taxable year be-
ginning in the same calendar year. The
general rule of § 152(c)(4)(A) applies if
oneornotaxpayerclaimingthechildis
the child’s parent. Under § 152(c)(4)(A),
the child is treated as the qualifying child
of (i) the taxpayer who is the child’s par-
ent, or (ii) if none of the taxpayers is the
child’s parent, the taxpayer with the high-
est adjusted gross income for that taxable
year.
The rule of § 152(c)(4)(B) applies if
both taxpayers claiming the child as a
qualifying child are the child’s parents
who do not file a joint return together.
Under § 152(c)(4)(B), the child is treated
as the qualifying child of the parent with
whom the child resides for the longer pe-
riod of time during the taxable year. If
the child resides with both parents for the
same amount of time during the taxable
year, the child is treated as the qualifying
child of the parent with the higher adjusted
gross income for that taxable year.
Special rule for certain noncustodial
parents
Notwithstanding the rule of
§152(c)(4)(B), a child may be treated as
the qualifying child of the noncustodial
parent, for certain purposes, under the
special rule of § 152(e). The noncustodial
parent may claim the child as a qualifying
child under § 152(e), if:
(1) the child is in the custody of one or
both parents for more than one-half of the
calendar year;
(2) the child receives over one-half of
the child’s support during the calendar
year from the child’s parents;
(3) the parents—
(a) are divorced or separated under a
decree of divorce or separate maintenance,
(b) are separated under a written sepa-
ration agreement, or
(c) live apart at all times during the last
6 months of the calendar year; and
(4) the custodial parent releases the
claim to the exemption to the noncustodial
parent in a written declaration that the
noncustodial parent attaches to the non-
custodial parent’s tax return.
Section 152(e)(4) defines “custodial
parent” as the parent having custody of the
child for the greater portion of the calen-
dar year, and “noncustodial parent” as the
parent who is not the custodial parent.
The special rule of § 152(e) allows a
noncustodial parent to claim the child as
a qualifying child only for purposes of the
child tax credit under § 24 and the de-
pendency deduction under § 151. Sec-
tion 152(e) does not apply to determina-
tions under §§ 2(b), 21(b) and 129 (see
§ 21(e)(5)), and 32(c)(3).
APPLICATION
Except to the extent that § 152(e) ap-
plies, under § 152(c)(4), when more than
one taxpayer claims a child as a qualify-
ing child, the child is treated as the quali-
fying child of only one taxpayer for all the
provisions that employ the uniform defini-
tion of a qualifying child (head of house-
hold filing status under § 2(b), the child
and dependent care credit under § 21, the
child tax credit under § 24, the earned in-
come credit under § 32, the exclusion for
dependent care assistance under § 129, and
the dependency deduction under § 151).
This rule is applied to these provisions as a
group, rather than on a section-by-section
basis.
If § 152(e) applies, a child may be
treated as the qualifying child of two
taxpayers. A noncustodial parent may
claim the child as a qualifying child under
§ 152(e) only for purposes of the child
tax credit under § 24 and the dependency
deduction under § 151. However, the non-
custodial parent may not claim the child
as a qualifying child under § 152(e) in
determining head of household filing sta-
tus under § 2(b), the earned income credit
under § 32, the child and dependent care
credit under § 21, or the exclusion from in-
come for dependent care assistance under
§ 129. Only the custodial parent (or other
eligible taxpayer) may claim the child as a
qualifying child for those purposes.
EXAMPLES
In the examples below, each individual
is a citizen of the United States and uses
a calendar taxable year, and the child is a
qualifying child (as defined in § 152(c)) of
each taxpayer. Unless otherwise indicated,
these examples assume that each individ-
ual meets the other requirements for claim-
ing a benefit described in the example.
Example 1. (i) A child, mother, and grandmother
share the same principal place of abode. The mother
is not married and is not the qualifying child of the
grandmother, and the grandmother is not the mother’s
dependent.
(ii) The mother claims the child as a qualifying
child for purposes of the earned income credit under
§32.
(iii) The child is treated as the qualifying child of
the mother for purposes of the earned income credit.
Because the mother claims the child as a qualifying
child for purposes of the earned income credit, under
§ 152(c)(4)(A), the child may not be treated as the
qualifying child of the grandmother for any purpose.
(iv) If, however, the mother does not claim the
child as a qualifying child for any purpose, the child
may be treated as the qualifying child of the grand-
mother for purposes of theearned income credit un-
der § 32 as well as head of household filing status un-
der § 2(b), the dependency deduction under § 151, the
child tax credit under § 24, the child and dependent
care credit under § 21, and the exclusion from income
for dependent care assistance under § 129, if applica-
ble, assuming that no other taxpayer claims the child
as a qualifying child.
Example 2. (i) The facts are the same as inExam-
ple 1, except that the mother and father of the child
are divorced, the father is the noncustodial parent, the
October 10, 20066812006–41 I.R.B.

mother has released the claim to the exemption to the
father in a written declaration under § 152(e), and the
father attaches the written declaration to his return
and claims the child as a qualifying child for purposes
of the dependency deduction and the child tax credit.
(ii) Under § 152(e), the child is treated as the qual-
ifying child of the father for purposes of the depen-
dency deduction and the child tax credit. The child
is treated as the qualifying child of the mother for
purposes of the earned income credit and, if appli-
cable, head of household filing status, the child and
dependent care credit, and the exclusion from income
for dependent care assistance. The child may not be
treated as the qualifying child of the grandmother for
any purpose.
Example 3. (i) The father and mother of a child
are married to each other. The father, mother, and
child share the same principal place of abode for the
first 8 months of the year. For the last 4 months of
the year, the parents live apart from each other, and
the mother and child share the same principal place
of abode. The parents file separate tax returns for
the taxable year. Consequently, neither parent may
claim head of household filing status, an earned in-
come credit, or a child and dependent care credit, be-
causeingeneral§2(b)appliesonlytounmarriedin-
dividuals, while §§ 32(d) and 21(e)(2), respectively,
require married individuals to file a joint return.
(ii) The father claims the child as a qualifying
child for purposes of the dependency deduction under
§ 151 and the exclusion for dependent care assistance
under § 129. The mother claims the child as a quali-
fying child for purposes of the dependency deduction
under § 151, the child tax credit under § 24, and the
exclusion for dependent care assistance under § 129.
(iii) Under the tie-breaking rule of § 152(c)(4)(B),
the child is treated as the qualifying child of the
mother because the child resided with the mother
for the longer period of time during the taxable year.
Therefore, the child is the qualifying child of the
mother for purposes of the dependency deduction,
the child tax credit, and the exclusion for depen-
dent care assistance. Section 152(e) does not apply
because the mother and father are not divorced or
separated under a decree ofseparate maintenance or
written separation agreement at the end of the taxable
year and did not live apart for the last 6 months of
the calendar year. Therefore, the child may not be
treated as the qualifying child of the father for any
purpose.
(iv) If, however, the mother does not claim the
child as a qualifying child for any purpose, the child
is treated as the qualifying child of the father for
purposes of the dependency deduction under § 151
and the exclusion for dependent care assistance un-
der § 129.
Example 4. (i) The facts are the same as inExam-
ple 3, except that the mother and father are separated
under a written separation agreement at the end of the
taxable year, the mother is the custodial parent and
has released the claim to the exemption to the father
in a written declaration under § 152(e), and the father
attaches the Form 8332 to his return and claims the
child as a qualifying child for purposes of the depen-
dency deduction, the child tax credit, and the exclu-
sion for dependent care assistance under § 129.
(ii) Because § 152(e) applies, the child is treated
as the qualifying child of the father for purposes of the
dependency deduction and the child tax credit. The
child is not treated as the qualifying child of the father
for purposes of the exclusion for dependent care as-
sistance because the father is the noncustodial parent
and, under § 21(e)(5), only the custodial parent may
claim the child as a qualifying child for purposes of
the exclusion for dependent care assistance. There-
fore, the tie-breaking rule of § 152(c)(4)(B) applies,
and the child is treated as the qualifying child of the
mother for purposes of the exclusion for dependent
care assistance.
Example 5. (i) The father and mother of two chil-
dren are married to each other. The father, mother,
and both children share the same principal place of
abode for the entire year. The father and mother
file separate tax returns for the taxable year. Conse-
quently, neither parent may claim head of household
filing status, an earned income credit, or a child and
dependent care credit, because in general § 2(b) ap-
plies only to unmarried individuals, while §§ 32(d)
and 21(e)(2), respectively,require married individu-
als to file a joint return.
(ii) The father claims the older child as a qualify-
ing child for purposes of the child tax credit, depen-
dency deduction, and exclusion for dependent care
assistance. The mother claims the younger child as
a qualifying child for purposes of the child tax credit,
dependency deduction, and exclusion for dependent
care assistance.
(iii) The older child is treated as the qualifying
child of the father and the younger child is treated as
the qualifying child of the mother. The tie-breaking
rule of § 152(c)(4)(B) does not apply because no two
taxpayers are claiming the same child as a qualifying
child for any of the benefits.

SUPPLEMENTAL INFORMATION:
Background and Explanation of
Provisions
I. Section 1221(a)(4) Language,
Legislative History, and Regulations
Section 1221 defines a capital asset
as all property held by a taxpayer unless
specifically excepted.Section 1221(a)(4)
treats accounts or notes receivable ac-
quired in the ordinary course of trade or
business for services rendered or from
the sale of property described in section
1221(a)(1) as ordinary assets.
Congress enacted section 1221(a)(4) in
1954 to correct a character mismatch prob-
lem. Before its enactment, the value of
accounts or notes receivable acquired for
rendering services or selling inventory was
taken into account by a taxpayer as ordi-
nary income, but gain or loss on a later dis-
position of the receivables was given capi-
tal treatment. Section 1221(a)(4) corrected
this mismatch by treating the accounts or
notes receivable as ordinary assets.
The legislative history confirms this
limited focus by referring explicitly to
accounts and notes receivable acquired
“in payment for” inventory or services
rendered by the holder. The specific prob-
lem being addressed by the enactment of
section 1221(a)(4) was described in the
House Report:
Paragraph (4) is a new provision
which excepts from the definition of
capital assets accounts or notes receiv-
able acquired in the ordinary course of
trade or business for services rendered
or from the sale of property described
in paragraph (1), that is, stock in trade
or inventory or property held for sale
to customers in the ordinary course of
trade or business. This will change
present law treatment, for example, as
follows: If a taxpayer acquires a note or
account receivable in payment for in-
ventory or services rendered, reports it
as income and sells it at a discount, then
this amendment will provide ordinary
loss treatment. Under present law such
loss treatment is only allowed if the tax-
payer is also, in effect, a dealer in such
accounts or notes. Alternatively, the
taxpayer may sell the account or note
for something more than the discounted
value that was originally reported. Un-
der present law this difference would
be capital gain unless the taxpayer is
such a dealer. The amendment will
cause such gain to be ordinary income.
H. R. Rep. No. 1337, 83d Cong., 2d Sess.,
A273–74 (1954).
The longstanding regulation interpret-
ing section 1221(a)(4) also confirms this
limited focus. Section 1.1221–1(a) of the
Income Tax Regulations states that the
termcapital assetsincludes all classes
of property not specifically excluded by
section 1221. Section 1.1221–1(d), which
addresses the section 1221(a)(4) exclu-
sion, repeats the statutory language of
section 1221(a)(4) and then interprets it to
apply as follows:
Thus, if a taxpayer acquires a note re-
ceivable for servicesrendered, reports
the fair market value of the note as in-
come, and later sells the note for less
than the amount previously reported,
the loss is an ordinary loss. On the other
hand, if the taxpayer later sells the note
for more than the amount originally re-
ported, the excess is treated as ordinary
income.
II. Expansion of Section 1221(a)(4)
Notwithstanding the above, section
1221(a)(4) has been applied more expan-
sively. The initial expansion occurred with
respect to notes obtained in loan origina-
tions. InBurbank Liquidating Corp. v.
Commissioner, 39 T.C. 999 (1963),acq.
sub nom. United Assocs., Inc., 1965–1
C.B. 3,aff’d. in part and rev’d. in part
on other grounds, 335 F.2d 125 (9
th
Cir.
1964), the Tax Court held that mortgage
loans originated by a savings and loan as-
sociation in the ordinary course of its busi-
ness were, in the hands of that association,
ordinary assets under section 1221(a)(4)
because they were notes receivable ac-
quired for the service of making loans. In
addition to acquiescing to the decision, the
Service relied uponBurbank Liquidating
October 10, 20066832006–41 I.R.B.

in a series of revenue rulings treating loans
made by commercial lenders (including
banks and REITs) as ordinary assets under
section 1221(a)(4) when held by the origi-
nal lender. See Rev. Rul. 72–238, 1972–1
C.B. 65; Rev. Rul. 73–558, 1973–2 C.B.
298; Rev. Rul. 80–56, 1980–1 C.B. 154;
Rev. Rul. 80–57, 1980–1 C.B. 157. See
§601.601(d)(2) of this chapter.
Historically, a lending transaction was
sometimes thought of as rendering a ser-
vice to the borrower. See Rev. Rul.
70–540, 1970–2 C.B. 101; Rev. Rul.
69–188, 1969–1 C.B. 54; Rev. Rul. 68–6,
1968–1 C.B. 325. That characterization,
however, does not justify treating notes
acquired by an originator in a lending
transaction as ordinary assets under sec-
tion 1221(a)(4). That treatment strains
the language of the statute because the
notes are not issued by borrowers solely or
even predominantly forservices rendered.
Rather, the notes are, for the most part,
issued by the borrower to the lender in
exchange for money.
Subsequently, the Tax Court fur-
ther extended the application of section
1221(a)(4) inFederal National Mortgage
Association v. Commissioner, 100 T.C.
541 (1993) (FNMA), by applying that
provision to notes that were purchased
in transactions thatthe court considered
closely associated with the process of
origination. Although FNMA was not
an originator, the court used theBurbank
Liquidatinganalysis to extend section
1221(a)(4) treatment to mortgages pur-
chased by FNMA. The court justified
this result by pointing out that FNMA’s
purchasing activity was undertaken in
accordance with its statutorily defined
purpose “to provide supplementary assis-
tance to the secondary market for home
mortgages by providing a degree of liq-
uidity for mortgage investments.”FNMA,
100 T.C. at 545 (quoting the Housing Act
of 1954, ch. 649, title II, section 201, 12
U.S.C. 1716(a)). Because of this purpose,
the court concluded that the purchases
were “a service to the mortgage lending
business and the members thereof.”Id.at
578.
The expansion of section 1221(a)(4)
cannot be reconciled with Congress’
stated purpose for enacting the statute.
Acquisition of notes or mortgages using
consideration other than services or sec-
tion 1221(a)(1) property generally does
not trigger current ordinary income and so
does not create a potential for the character
mismatch that concerned Congress when
it enacted section 1221(a)(4).
The proposed regulation reflects a
conclusion by the Treasury Department
and the IRS that the extension of sec-
tion 1221(a)(4) to notes acquired by a
creditor in a lending transaction or to
notes purchased in the secondary mar-
ket is inconsistent with Congressional
intent and is unsound as a matter of tax
policy. In addition, the interpretation of
section 1221(a)(4) set forth inBurbank
LiquidatingandFNMAimpedes effective
administration of the tax laws by caus-
ing the status of the notes to hinge on
judgments as to whether the lending trans-
action or a subsequent secondary market
purchase of the notes provides a service
to the borrower or the mortgage lending
industry. Reliance on judgments such as
this fosters uncertainty and disputes.
Accordingly, the proposed regulation
clarifies that an account or note receiv-
able is not describedin section 1221(a)(4)
if, in exchange for the account or note
receivable, the taxpayer provides more
thande minimisconsideration other than
services or property described in section
1221(a)(1), or if the account or note receiv-
able is not issued by the party acquiring
the services or property described in sec-
tion 1221(a)(1). In particular, a note is not
acquired for services within the meaning
of section 1221(a)(4) on the grounds that
the taxpayer’s act of acquiring (including
originating) the account or note receivable
constitutes, or includes, the provision of
a service or services to the issuer of the
account or note receivable, to the sec-
ondary market in which accounts or notes
receivable of this sort may trade, or to the
participants in that market.
Effect on Other Documents
Rev. Rul. 72–238 and Rev. Rul.
73–558 are not determinative with respect
to future transactions because these rul-
ings apply to taxable years beginning be-
fore July 12, 1969, and were superseded
by section 582(c) of the Internal Revenue
Code of 1986. Accordingly, simultane-
ously with the publication of these pro-
posed regulations, those rulings are be-
ing declared obsolete. When final regu-
lations are published, the IRS will deter-
mine whether Rev. Rul. 80–56 and 80–57
should similarly be declared obsolete.
Proposed Effective Date
These regulations are proposed to apply
to accounts or notes receivable acquired
after the date the final regulations are pub-
lished in theFederal Register.
Special Analyses
It has been determined that this notice
of proposed rulemaking is not a signifi-
cant regulatory action as defined in Exec-
utive Order 12866. Therefore, a regula-
tory assessment is not required. It has also
been determined that section 553(b) of the
Administrative Procedure Act (5 U.S.C.
chapter 5) does not apply to these regu-
lations, and because the regulation does
not impose a collection of information on
small entitles, the Regulatory Flexibility
Act (5 U.S.C. chapter 6) does not apply.
Pursuant to section 7805(f) of the Code,
this notice of proposed rulemaking will be
submitted to the Chief Counsel for Advo-
cacy of the Small Business Administration
for comment on its impact on small busi-
ness.
Comments and Public Hearing
Before these proposed regulations are
adopted as final regulations, consideration
will be given to any written comments
(a signed original and eight (8) copies)
or electronic comments that are submit-
ted timely to the IRS. The Treasury De-
partment and IRS invite comments on the
proposed effective date, on the impact of
the proposed regulation on hedging prac-
tices of lending institutions or other tax-
payers to which section 582(c) does not ap-
ply, and on appropriate measures to deal
with that impact. Comments are specifi-
cally requested from taxpayers in the ac-
ceptance finance, debt collection, factor-
ing and personal finance industries on any
impact that the proposed regulation may
have. The Treasury Department and the
IRS also specifically request comments on
the clarity of the proposed rules and how
they can be made easier to understand. All
comments will be available for public in-
spection and copying.
A public hearing has been scheduled for
November 7, 2006, beginning at 10 a.m.
in the New Carrollton Auditorium, 5000
2006–41 I.R.B.684October 10, 2006

Ellin Road, Lanham, Maryland. All vis-
itors must present photo identification to
enter the building. Because of access re-
strictions, visitors will not be admitted be-
yond the immediate entrance area more
than 30 minutes before the 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 written or electronic comments and
an outline of the topics to be discussed
and the time to be devoted to each topic
(a signed original and eight (8) copies) by
October 17, 2006. A period of 10 minutes
will be allotted to each person for making
comments. An agenda showing the sched-
uling of the speakers will be prepared af-
ter the deadline for receiving outlines has
passed. Copies of the agenda will be avail-
able free of charge at the hearing.
Drafting Information
The principal author of these proposed
regulations is K. Scott Brown, Office
of the Associate Chief Counsel (Finan-
cial Institutions and Products). However,
other personnel from the IRS and Treasury
Department participated in their develop-
ment.

Proposed Amendments to the
Regulations
Accordingly, 26 CFR part 1 is proposed
to be 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 1.1221–1 is amended as
follows:
1. Paragraph (e) is redesignated as (f).
2. A new paragraph (e) is added.
The addition reads as follows:
§1.1221–1 Meaning of terms.
*****
(e)(1) An account or note receivable is
not described in section 1221(a)(4) if—
(i) In acquiring the account or note
receivable, the taxpayer provides more
thande minimisconsideration other than
services or property described in section
1221(a)(1); or
(ii) The obligor under the account or
note receivable is a person other than the
person acquiring the services or property
describedinsection1221(a)(1).
(2) In particular, an account or note
receivable is not described in section
1221(a)(4) on the grounds that the tax-
payer’s act of acquiring (including orig-
inating) the account or note receivable
constitutes, or includes, the provision of
a service or services to the issuer of the
account or note receivable, to the sec-
ondary market in which accounts or notes
receivable of this sort may trade, or to the
participants in that market. If a lender,
however, separately invoiced reasonable
fees for services that the lender rendered
to the borrower in connection with a lend-
ing transaction and if the lender received
as evidence of the obligation to make
payment of those fees an account or note
receivable that is separate from the debt
instrument that was originated in the lend-
ing transaction, then this paragraph (e)(2)
does not prevent the separate account or
note receivable from being described in
section 1221(a)(4).
(3) This paragraph (e) applies to ac-
counts or notes receivable acquired after
the date the final regulations are published
in theFederal Register.

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 rul-
ings 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.
