This revenue procedure provides a safe harbor for cer-
tain taxpayers that received a loan pursuant to the Pay-
check Protection Program (PPP) and, based on guidance
issued by the Department of the Treasury and the Internal
Revenue Service prior to the enactment of the COVID-re-
lated Tax Relief Act of 2020, enacted as Subtitle B of
Title II of Division N of the Consolidated Appropriations
Act, 2021, Public Law 116-260, 134 Stat. 1182 (Dec.
27, 2020), did not deduct certain otherwise deductible
expenses paid or incurred during the taxpayer’s taxable
year(s) ending after March 26, 2020, and on or before
December 31, 2020 (2020 taxable year) that resulted
in, or were expected to result in, forgiveness of the loan.
Under the safe harbor, such taxpayers may elect to de-
duct these expenses on the taxpayer’s timely filed orig-
inal Federal income tax return or information return, as
applicable, for the taxpayer’s first taxable year following
the taxpayer’s 2020 taxable year rather than filing an
amended return or administrative adjustment request for
the taxpayer’s 2020 taxable year.

Introduction
The Internal Revenue Bulletin is the authoritative instrument
of the Commissioner of Internal Revenue for announcing of-
ficial rulings and procedures of the Internal Revenue Service
and for publishing Treasury Decisions, Executive Orders, Tax
Conventions, legislation, court decisions, and other items of
general interest. It is published weekly.
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,
modify, or amend any of those previously published in the
Bulletin. All published rulings apply retroactively unless other-
wise indicated. Procedures relating solely to matters of inter-
nal management 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 rul-
ings to taxpayers or technical advice to Service field offices,
identifying details and information of a confidential nature are
deleted to prevent unwarranted invasions of privacy and to
comply with statutory requirements.
Rulings and procedures reported in the Bulletin do not have the
force and effect of Treasury Department Regulations, but they
may be used as precedents. Unpublished rulings will not be
relied on, used, or cited as precedents by Service personnel in
the disposition of other cases. In applying published rulings and
procedures, the effect of subsequent legislation, regulations,
court decisions, rulings, and procedures must be considered,
and Service personnel and others concerned are cautioned
against reaching the same conclusions in other cases unless
the facts and circumstances are substantially the same.
The Bulletin is divided into four parts as follows:
Part I.—1986 Code.
This part includes rulings and decisions based on provisions
of the Internal Revenue Code of 1986.
Part II.—Treaties and Tax Legislation.
This part is divided into two subparts as follows: Subpart A,
Tax Conventions and Other Related Items, and Subpart B,
Legislation 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
Rulings. Bank Secrecy Act Administrative Rulings are issued
by the Department of the Treasury’s Office of the Assistant
Secretary (Enforcement).
Part IV.—Items of General Interest.
This part includes notices of proposed rulemakings, disbar-
ment and suspension lists, and announcements.
The last Bulletin for each month includes a cumulative index
for the matters published during the preceding months. These
monthly indexes are cumulated on a semiannual basis, and are
published in the last Bulletin of each semiannual period.
The contents of this publication are not copyrighted and may be reprinted freely. A citation of the Internal Revenue Bulletin as the source would be appropriate.

Part III
2020 Section 45K(d)(2)(C)
Reference Price
Notice 2021-29
SECTION 1. PURPOSE
This notice publishes the reference
price under § 45K(d)(2)(C) of the In-
ternal Revenue Code for calendar year
2020. The credit period for the noncon-
ventional source production credit under
§ 45K ended on December 31, 2013, for
facilities producing coke or coke gas
(other than from petroleum based prod-
ucts). However, the reference price con-
tinues to apply in determining the amount
of the enhanced oil recovery credit under
§ 43, the marginal well production cred-
it for qualified crude oil production un-
der § 45I, and the applicable percentage
under § 613A to be used in determining
percentage depletion in the case of oil
and natural gas produced from marginal
properties.
SECTION 2. BACKGROUND
Section 45K(d)(2)(C) provides that the
term “reference price” means, with respect
to a calendar year, the Secretary’s estimate
of the annual average wellhead price per
barrel for all domestic crude oil the price
of which is not subject to regulation by the
United States.
Section 43(a) provides that, for pur-
poses of § 38, the enhanced oil recovery
credit for any taxable year is an amount
equal to 15 percent of the taxpayer’s qual-
ified enhanced oil recovery costs for such
taxable year.
Section 43(b)(1) provides that the
amount of enhanced oil recovery credit
for any taxable year shall be reduced by
an amount which bears the same ratio to
the amount of such credit (determined
without regard to this paragraph) as - (A)
the amount by which the reference price
for the calendar year preceding the cal-
endar year in which the taxable year be-
gins exceeds $28, bears to (B) $6. Section
43(b)(2) provides that the term “reference
price” means, with respect to any calendar
year, the reference price determined for
such calendar year under § 45K(d)(2)(C).
Section 45I(a) provides that, for pur-
poses of § 38, the marginal well pro-
duction credit for any taxable year is an
amount equal to the product of the credit
amount and the qualified crude oil produc-
tion and the qualified natural gas produc-
tion which is attributable to the taxpayer.
Section 45I(b)(1) provides that for
crude oil production, the amount of the
marginal well production credit is $3 per
barrel of qualified crude oil production.
Section 45I(b)(2) provides that the $3
amount under § 45I(b)(1) shall be reduced
(but not below zero) by an amount which
bears the same ratio to such amount (de-
termined without regard to this paragraph)
as – (i) the excess (if any) of the applica-
ble reference price over $15, bears to (ii)
$3. The applicable reference price for a
taxable year is the reference price of the
calendar year preceding the calendar year
in which the taxable year begins.
Section 45I(b)(2)(C) provides that for
qualified crude oil production the term
“reference price” means, with respect to
any calendar year, the reference price de-
termined under § 45K(d)(2)(C).
Section 613A(c)(6)(A) provides, in
general, that the allowance for depletion
under § 611 shall be computed in accor-
dance with § 613 with respect to - (i) so
much of the taxpayer’s average daily mar-
ginal production of domestic crude oil as
does not exceed the taxpayer’s depletable
oil quantity (determined without regard
to paragraph (3)(A)(ii)), and (ii) so much
of the taxpayer’s average daily margin-
al production of domestic natural gas as
does not exceed the taxpayer’s depletable
natural gas quantity (determined without
regard to paragraph (3)(A)(ii)), and the
applicable percentage shall be deemed to
be specified in subsection (b) of § 613 for
purposes of subsection (a) of that section.
Section 613A(c)(6)(C) provides that
the term “applicable percentage” means
the percentage (not greater than 25 per-
cent) equal to the sum of - (i) 15 percent,
plus (ii) 1 percentage point for each whole
dollar by which $20 exceeds the refer-
ence price for crude oil for the calendar
year preceding the calendar year in which
the taxable year begins. For purposes of
this paragraph, the term “reference price”
means, with respect to any calendar year,
the reference price determined for such
calendar year under § 45K(d)(2)(C).
SECTION 3. REFERENCE PRICE
The reference price under § 45K(d)(2)
(C) for calendar year 2020 is $37.07.

2021 Marginal Production
Rates
Notice 2021-30
This notice announces the applicable
percentage under § 613A of the Internal
Revenue Code to be used in determining
percentage depletion for marginal proper-
ties for the 2021 calendar year.
Section 613A(c)(6)(C) defines the term
“applicable percentage” for purposes of
determining percentage depletion for oil
and gas produced from marginal prop-
erties. The applicable percentage is the
percentage (not greater than 25 percent)
equal to the sum of 15 percent, plus one
percentage point for each whole dollar
by which $20 exceeds the reference price
(determined under § 45K(d)(2)(C)) for
crude oil for the calendar year preceding
the calendar year in which the taxable year
begins. The reference price determined
under § 45K(d)(2)(C) for the 2020 calen-
dar year is $37.07.
The following table contains the appli-
cable percentages for marginal production
for taxable years beginning in calendar
years 1991 through 2021.

Rev. Proc. 2021-20
SECTION 1. PURPOSE
This revenue procedure provides a
safe harbor for certain taxpayers that re-

ceived a loan pursuant to the Paycheck
Protection Program (PPP) and, based on
guidance issued by the Department of
the Treasury (Treasury Department) and
the Internal Revenue Service (IRS) prior
to the enactment of the COVID-related
Tax Relief Act of 2020 (COVID-relat-
ed Tax Relief Act), enacted as Subtitle B
of Title II of Division N of the Consolidat-
ed Appropriations Act, 2021 (Appropria-
tions Act), Public Law 116-260, 134 Stat.
1182 (Dec. 27, 2020), did not deduct cer-
tain otherwise deductible expenses paid
or incurred during the taxpayer’s taxable
year(s) ending after March 26, 2020, and
on or before December 31, 2020 (2020
taxable year) that resulted in, or were ex-
pected to result in, forgiveness of the loan.
Under the safe harbor, such taxpayers may
elect to deduct these expenses on the tax-
payer’s timely filed original Federal in-
come tax return or information return, as
applicable, for the taxpayer’s first taxable
year following the taxpayer’s 2020 tax-
able year rather than filing an amended re-
turn or administrative adjustment request
for the taxpayer’s 2020 taxable year.
SECTION 2. BACKGROUND
.01 PPP Prior to Enactment of the Ap-
propriations Act.
(1) Sections 1102 and 1106 of the
Coronavirus Aid, Relief, and Economic
Security Act (CARES Act), Public Law
116-136, 134 Stat. 281, 286-93 (Mar.
27, 2020), established the PPP as a loan
program administered by the U.S. Small
May 10, 2021 1150 Bulletin No. 2021–19

Bulletin No. 2021–19 1151 May 10, 2021
Business Administration (SBA) as part
of its “7(a) Loan Program” (15 U.S.C.
636(a)) to provide economic assistance
to small businesses nationwide adversely
impacted by the COVID–19 emergency.
See Business Loan Program Temporary
Changes; Paycheck Protection Program,
85 FR 20811 (Apr. 15, 2020). Under the
PPP as it existed prior to enactment of the
Appropriations Act, the SBA was permit-
ted to guarantee the full principal amount
of a covered loan, defined by § 1102(a)(2)
of the CARES Act as a loan made under
the PPP during the period beginning on
February 15, 2020, and ending on Decem-
ber 31, 2020 (original PPP covered loan).
See § 1102(a)(2) of the CARES Act; Pay-
check Protection Program Flexibility Act
of 2020, Public Law 116-142, 134 Stat.
641 (June 5, 2020).
(2) Prior to the enactment of the Ap-
propriations Act, under § 1106(b) of the
CARES Act, an individual or entity that
was eligible to receive an original PPP
covered loan (original eligible recipient)
could receive forgiveness of the full prin-
cipal amount of the loan up to an amount
equal to the following costs incurred and
payments made during the original PPP
covered period: (1) payroll costs, (2) inter-
est on a covered mortgage obligation, (3)
any covered rent obligation payment, and
(4) any covered utility payment (original
eligible expenses).
(3) Prior to the enactment of the Ap-
propriations Act, § 1106(i) of the CARES
Act provided that, for purposes of the In-
ternal Revenue Code (Code), “any amount
which (but for this subsection) would be
includible in gross income of the eligible
recipient by reason of forgiveness de-
scribed in subsection (b) shall be exclud-
ed from gross income.” Section 1106(i)
of the CARES Act excluded the amount
from gross income regardless of whether
the amount would be (1) income from the
discharge of indebtedness under § 61(a)
(11) of the Code, or (2) otherwise includi-
ble in gross income under § 61.
.02 Guidance Issued Prior to Enact-
ment of the COVID-related Tax Relief
Act. On April 30, 2020, the Treasury
Department and the IRS released Notice
2020-32, 2020-21 IRB 837 (May 18,
2020), which clarified that no deduction
was allowed for an otherwise deductible
expense if the payment of the expense
resulted in forgiveness of an original
PPP covered loan. On November 18,
2020, the Treasury Department and the
IRS released Rev. Rul. 2020-27, 2020-
50 IRB 1552 (December 7, 2020), which
held that a taxpayer that incurred other-
wise deductible expenses in its 2020 tax-
able year could not deduct those expens-
es if, at the end of the taxpayer’s 2020
taxable year, the taxpayer had a rea-
sonable expectation of reimbursement
of the expenses in the form of covered
loan forgiveness. Also on November
18, 2020, the Treasury Department and
the IRS released Rev. Proc. 2020-51,
2020-50 IRB 1599 (December 7, 2020),
which provided a safe harbor to address
situations covered by Rev. Rul. 2020-27
when the taxpayer’s expectation of cov-
ered loan forgiveness was not realized in
a subsequent taxable year.
.03 Enactment of the COVID-related
Tax Relief Act.
(1) On December 27, 2020, the Appro-
priations Act was enacted. Section 304(b)
(1)(A) of the Economic Aid to Hard-Hit
Small Businesses, Nonprofits, and Ven-
ues Act (Economic Aid Act), which was
enacted as Title III of Division N of the
Appropriations Act, redesignated § 1106
of the CARES Act as § 7A of the Small
Business Act, transferred the section to
the Small Business Act (15 U.S.C. § 631
et seq.), and inserted that section so as to
appear after § 7 of the Small Business Act
(15 U.S.C. § 636)). Section 276(a)(1) of
the COVID-related Tax Relief Act amend-
ed § 7A(i) of the Small Business Act to
provide new rules regarding the Federal
income tax consequences of forgiveness
of original PPP covered loans. Specifi-
cally, § 7A(i) of the Small Business Act
provides, in relevant part, that “no amount
shall be included in the gross income of
the eligible recipient by reason of forgive-
ness of indebtedness [on an original PPP
covered loan],” and “no deduction shall be
denied, no tax attribute shall be reduced,
and no basis increase shall be denied, by
reason of [that] exclusion from gross in-
come.”
(2) Rev. Rul. 2021-2, 2021-4 IRB 495
(Jan. 25, 2021), which was released on
January 6, 2021, obsoleted Notice 2020-
32 and Rev. Rul. 2020-27 due to the en-
actment of § 276(a) of the COVID-related
Tax Relief Act. Rev. Rul. 2021-2 provides

that, as of December 27, 2020, the con-
clusion stated in Notice 2020-32 and the
holding stated in Rev. Rul. 2020-27 are
no longer accurate statements of the law.
Likewise, the legal premise underlying
Rev. Proc. 2020-51 is no longer accurate
and, as of December 27, 2020, taxpayers
could not have complied with the require-
ments of section 3.01 or 3.02 of Rev. Proc.
2020-51.
SECTION 3. SAFE HARBOR TO
DEDUCT ORIGINAL ELIGIBLE
EXPENSES IN IMMEDIATELY
SUBSEQUENT TAXABLE YEAR
.01 Safe Harbor. Subject to the lim-
itations described in section 3.05 of this
revenue procedure, a taxpayer may elect
to deduct otherwise deductible original el-
igible expenses on the taxpayer’s timely
filed, including extensions, original Fed-
eral income tax return or information re-
turn, as applicable, for the taxpayer’s im-
mediately subsequent taxable year, rather
than on an amended return or administra-
tive adjustment request for the taxpayer’s
2020 taxable year in which the expenses
were paid or incurred, if the taxpayer--
(1) Is a “Covered Taxpayer,” as defined
in section 3.02 of this revenue procedure;
and
(2) Satisfies all of the requirements
described in section 3.04 of this revenue
procedure.
.02 Covered Taxpayer. A Covered Tax-
payer is a taxpayer that satisfies all of the
following:
(1) The taxpayer received an original
PPP covered loan;
(2) The taxpayer paid or incurred orig-
inal eligible expenses during the taxpay-
er’s 2020 taxable year;
(3) On or before December 27, 2020,
the taxpayer timely filed, including ex-
tensions, a Federal income tax return or
information return, as applicable, for the
taxpayer’s 2020 taxable year; and
(4) On the taxpayer’s Federal income
tax return or information return, as ap-
plicable, the taxpayer did not deduct the
original eligible expenses because--
(a) The expenses resulted in forgive-
ness of the original PPP covered loan; or
(b) The taxpayer reasonably expected
at the end of the 2020 taxable year that the
expenses would result in such forgiveness.

May 10, 2021 1152 Bulletin No. 2021–19
.03 Expenses Not Covered by the Safe
Harbor. This revenue procedure does not
apply to expenses described in sections
3.03(1) or (2) of this revenue procedure.
(1) Section 304(b)(2) of the Econom-
ic Aid Act expanded the list of expens-
es for which an individual or entity that
received an original PPP covered loan
could receive forgiveness. See § 7A(a)
of the Small Business Act (as amended
by § 304(b)(2) of the Economic Aid Act).
However, because those new expenses
were not included as part of the original
eligible expenses, those expenses are not
eligible to be deducted through an election
by a Covered Taxpayer to apply the safe
harbor provided by section 3.01 of this
revenue procedure.
(2) Section 311(a) of the Econom-
ic Aid Act amended § 7(a) of the Small
Business Act to authorize Paycheck Pro-
tection Program Second Draw Loans
(PPP Second Draw Loans) under the
same terms, conditions, and processes
as original PPP covered loans. See § 7(a)
(37)(B) of the Small Business Act (as
added by § 311(a) of the Economic Aid
Act). PPP Second Draw Loans are not
original PPP covered loans, and therefore
eligible expenses that may result in for-
giveness of such loans are not covered by
this revenue procedure.
.04 Time and Manner for Making Elec-
tion to Apply Safe Harbor. To make a valid
election to apply the safe harbor provided
by section 3.01 of this revenue procedure,
a Covered Taxpayer must satisfy the fol-
lowing conditions:
(1) Election deadline. A Covered Tax-
payer must make the election by attach-
ing the statement described in section
3.04(2) of this revenue procedure to the
Covered Taxpayer’s timely filed, includ-
ing extensions, Federal income tax return
or information return, as applicable, for
the Covered Taxpayer’s first taxable year
following the Covered Taxpayer’s 2020
taxable year in which the original eligible
expenses were paid or incurred.
(2) Requirements for statement. The
statement required by section 3.04(1)
of this revenue procedure must be titled
“Revenue Procedure 2021-20 Statement”
(and named RevProc2021-20.pdf for e-file
attachments) and include the following in-
formation:
(a) The Covered Taxpayer’s name, ad-
dress, and social security number or tax-
payer identification number;
(b) A statement that the Covered Tax-
payer is applying the safe harbor provided
by section 3.01 of this revenue procedure;
(c) The amount and date of disburse-
ment of the taxpayer’s original PPP cov-
ered loan; and
(d) A list, including descriptions and
amounts, of the original eligible expenses
paid or incurred by the Covered Taxpayer
during the Covered Taxpayer’s 2020 tax-
able year that are reported on the Federal
income tax return or information return,
as applicable, for the Covered Taxpayer’s
first taxable year following that 2020 tax-
able year.
.05 Safe Harbor Limitations. The safe
harbor provided by section 3.01 of this
revenue procedure does not preclude the
IRS from--
(1) Examining any issues relating to
the claimed deductions for original el-
igible expenses, including determining
whether a taxpayer is a Covered Taxpayer
under this revenue procedure, the amount
of the deduction, and whether the Covered
Taxpayer has substantiated the deduction
claim; or
(2) Requesting additional information
or documentation verifying any amounts
described in the statement required by
section 3.04(1) of this revenue procedure.
SECTION 4. EFFECT ON OTHER
DOCUMENTS
Rev. Proc. 2020-51 is obsolete.
SECTION 5. EFFECTIVE DATE
This revenue procedure is effective for
any taxable year ending in calendar year
2020 and for the immediately subsequent
taxable year.
SECTION 6. PAPERWORK
REDUCTION ACT
.01 This revenue procedure provides
procedures by which Covered Taxpayers
may apply the safe harbor provided by
section 3.01 of this revenue procedure.
To elect to apply that safe harbor, Cov-
ered Taxpayers must file a statement in
accordance with all of the requirements
described in section 3.04(2) of this reve-
nue procedure. The collection of informa-
tion will be associated with the Federal
income tax returns or information returns
to which that statement will be attached.
That collection of information has been
reviewed and approved by the Office of
Management and Budget in accordance
with the Paperwork Reduction Act (44
U.S.C. 3507(c)) under--
(1) control number 1545–0123 for busi-
ness filers (https://www.federalregister.
gov/documents/2018/10/09/2018-21846/
proposed-collection-comment-request-
for-forms-1065-1065-b-1066-1120-1120-
c-1120-f-1120-h-1120-nd); and
(2) control number 1545-074 for
individual filers (https://www.regin-
fo.gov/public/do/PRAViewICR?ref_
nbr=201808-1545-031).
.02 The information described in sec-
tion 6.01 of this revenue procedure is
required to be collected and retained for
compliance purposes. Specifically, that
information will be used by the IRS to
(1) determine whether a Covered Tax-
payer has elected to apply the safe harbor
provided by section 3.01 of this revenue
procedure, (2) determine that the amount
claimed on the Federal income tax or in-
formation return filed by the Covered Tax-
payer is correct, and (3) ensure that any
future action that is inconsistent with the
election by the Covered Taxpayer to apply
the safe harbor provided by section 3.01
of this revenue procedure is properly ad-
dressed, including through the potential
application of equitable estoppel or the
doctrine of consistency.
.03 The Treasury Department and the
IRS estimate that the maximum number
of respondents under this revenue proce-
dure would be 6,762,181. This number
was determined by examining the PPP
data for the total number of approved
original PPP covered loans. See https://
www.sba.gov/funding-programs/loans/
coronavirus-relief-options/paycheck-pro-
tection-program/ppp-data. This data is
current through March 28, 2021. Because
some taxpayers will not elect to apply the
safe harbor provided by section 3.01 of
this revenue procedure, the number of es-
timated respondents is on the high end of
the estimate.

Bulletin No. 2021–19 1153 May 10, 2021
.04 The maximum estimated number
of respondents under this revenue proce-
dure is 6,762,181. The estimated annual
burden per respondent or recordkeeper
varies between 0 and 30 minutes, de-
pending on individual circumstances,
with an estimated average of 15 minutes.
The estimated total annual reporting and/
or recordkeeping burden is approximate-
ly 1,690,545 hours (6,762,181 respon-
dents * 15 minutes). The estimated annu-
al cost burden to respondents is $95 per
hour. Accordingly, the Treasury Depart-
ment and the IRS expect the total annual
cost burden for the statements required
by section 3.04(1) of this revenue proce-
dure to be approximately $160,601,799
(6,762,181 * 0.25 * $95). The estimated
annual frequency of responses is once
because that statement must be filed only
once.

Rev. Proc. 2021-23
SECTION 1. PURPOSE
This revenue procedure supersedes
sections 3.05 (Child Tax Credit) and
3.07 (Earned Income Credit) of Rev.
Proc. 2020-45, 2020-46 I.R.B. 1016,
and section 2.01 of Rev. Proc. 2020-36,
2020-32 I.R.B. 243 (Applicable Percent-
age Table for 2021), to reflect statutory
amendments made by the American Res-
cue Plan Act of 2021, Pub. L. No. 117-2
(ARP). Rev. Proc. 2020-45 sets forth in-
flation-adjusted items for 2021, for var-
ious provisions of the Internal Revenue
Code of 1986 (Code). Rev. Proc. 2020-36
updates the applicable percentage table
in § 36B(b)(3)(A)(i) of the Code (Appli-
cable Percentage Table) used to calculate
a taxpayer’s premium tax credit (PTC)
and the required contribution percentage
used to determine whether an individual
is eligible for employer-sponsored mini-
mum essential coverage for calendar year
2021.
SECTION 2. CHANGES
.01 Solely for taxable years beginning
in 2021, section 9611 of the ARP increas-
es the child tax credit under § 24 of the
Code to $3,000 for qualifying children
who have attained age 6 but not 18 by the
end of the 2021 taxable year, and $3,600
for qualifying children who have not at-
tained age 6.
.02 Solely for taxable years beginning
in 2021, section 9621 of the ARP tempo-
rarily modifies the Earned Income Credit
(EIC) under § 32 of the Code to provide
special rules, including, for example, spe-
cial rules for eligible individuals with no
qualifying children and applicable phase-
out amounts.
.03 For taxable years beginning in
or after 2021, section 9624 of the ARP
modifies § 32(i) of the Code to provide
that the EIC is not available for taxpayers
whose aggregate amount of disqualified
income exceeds $10,000. This amount
will be adjusted for inflation for taxable
years beginning after December 31,
2021.
.04 For taxable years beginning in 2021
and 2022, section 9661 of the ARP Act
amends the Applicable Percentage Table
in § 36B(b)(3)(A) of the Code to provide
temporary percentages. Taxpayers use the
applicable percentages in § 36B(b)(3)(A)
to determine the amount of the PTC they
may claim for a taxable year. Section 9661
does not amend the required contribution
percentage that a taxpayer uses to deter-
mine whether the taxpayer and members
of the taxpayer’s family are eligible for
employer-sponsored minimum essential
coverage. See § 36B(c)(2)(C)(i)(ll). Con-
sequently, the required contribution per-
centage of 9.83 percent for 2021 provided
in section 2.02 of Rev. Proc. 2020-36 is
unchanged.
SECTION 3. 2021 INCREASED
REFUNDABLE CHILD
TAX CREDIT
For taxable years beginning in 2021,
the child tax credit is refundable for cer-
tain taxpayers up to $3,000 for each qual-
ifying child age 6 or older and $3,600
for each qualifying child who has not
attained age 6. A taxpayer is eligible for
the increased refundable amount only if
the taxpayer, or the spouse of a taxpayer
filing a joint return, had a main home in
the United States for more than half of
the taxable year beginning in 2021 or was
a bona fide resident of Puerto Rico for the
taxable year beginning in 2021. For all
other taxpayers, the refundable portion
of the credit is limited to $1,400 under
§ 24(h)(5)(A).
SECTION 4. 2021 EARNED INCOME
CREDIT AS MODIFIED AND
SUPERSEDED
.01 Earned Income Credit
(1) In general. For taxable years be-
ginning in 2021, the following amounts
are used to determine the EIC under
§ 32(b). The ”earned income amount”
is the amount of earned income at or
above which the maximum amount of
the earned income credit is allowed.
The “threshold phaseout amount” is the
amount of adjusted gross income (or, if
greater, earned income) above which the
maximum amount of the credit begins
to phase out. The ”completed phaseout
amount” is the amount of adjusted gross
income (or, if greater, earned income)
at or above which no credit is allowed.
The threshold phaseout amounts and the
completed phaseout amounts shown in
the table below for married taxpayers
filing a joint return include the increase
provided in § 32(b)(2)(B), as adjusted
for inflation for taxable years beginning
in 2021.

Bulletin No. 2021–19 i May 10, 2021
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
effect:
Amplified describes a situation where
no change is being made in a prior pub-
lished position, but the prior position is
being extended to apply to a variation of
the 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 with
modified, below).
Clarified is 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 rul-
ing is being changed.
Distinguished describes a situation
where a ruling mentions a previously pub-
lished ruling and points out an essential
difference between them.
Modified is 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
with amplified and clarified, above).
Obsoleted describes a previously pub-
lished ruling that is not considered deter-
minative with respect to future transactions.
This term is most commonly used in a ruling
that lists previously published rulings 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.
Revoked describes situations where the
position in the previously published ruling
is not correct and the correct position is
being stated in a new ruling.
Superseded describes a situation where
the new ruling does nothing more than
restate the substance and situation of a
previously published ruling (or rulings).
Thus, the term is used to republish under
the 1986 Code and regulations the same
position published under the 1939 Code
and regulations. The term is also used
when it is desired to republish in a single
ruling a series of situations, names, etc.,
that were previously published over a
period of time in separate rulings. If the
new ruling does more than restate the sub-
stance of a prior ruling, a combination of
terms is used. For example, modified and
superseded describes 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 previous-
ly published ruling in a new ruling that is
self contained. In this case, the previously
published ruling is first modified and then,
as modified, is superseded.
Supplemented is 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
ruling has been supplemented several
times, a new ruling may be published that
includes the list in the original ruling and
the additions, and supersedes all prior rul-
ings in the series.
Suspended is used in rare situations to
show that the previous published rulings
will not be applied pending some future
action such as the issuance of new or
amended regulations, the outcome of cas-
es in litigation, or the outcome of a Ser-
vice study.
