Rev. Proc. 2024-34

SECTION 1. PURPOSE
This revenue procedure modifies section 7 of Rev. Proc. 2024-23, 2024-23 I.R.B.
1334, to modify the procedures under § 446 of the Internal Revenue Code (Code)
1
and
§ 1.446-1(e) for obtaining automatic consent of the Commissioner of Internal Revenue
(Commissioner) to change methods of accounting for expenditures paid or incurred in
taxable years beginning after December 31, 2021, to comply with § 174 or to rely on
interim guidance provided in sections 3 through 7 of Notice 2023-63, 2023-39 I.R.B.
919, as modified by Notice 2024-12, 2024-5 I.R.B. 616. References in this revenue
procedure to “former § 174” refer to that section as in effect for research or experimental
expenditures paid or incurred in taxable years beginning before January 1, 2022, that is,

1
Unless otherwise specified, all “section” or “§” references are to sections of the Code or the Income Tax
Regulations (26 CFR part 1).

2
prior to the effective date of the amendments made to § 174 by § 13206(a) of Public
Law 115-97, 131 Stat. 2054 (Dec. 22, 2017), commonly referred to as the Tax Cuts and
Jobs Act (TCJA). References to “§ 174” in this revenue procedure refer to § 174 as
amended by the TCJA.
SECTION 2. BACKGROUND
.01 Treatment of research and experimental expenditures under former § 174.

Former § 174 allowed taxpayers to elect to deduct research or experimental
expenditures paid or incurred in connection with a trade or business as current
expenses, to capitalize and amortize such expenditures over a period of not less than
60 months, or to charge such expenditures to capital account.
.02 Treatment of SRE expenditures under § 174.

(1) Section 13206(a) of the TCJA amended former § 174. For amounts paid or
incurred in taxable years beginning after December 31, 2021, that meet the definition of
specified research or experimental (SRE) expenditures under § 174(b), § 174(a)(1)
disallows deductions for such amounts, except as provided in § 174(a)(2). Section
174(a)(2) requires taxpayers to charge SRE expenditures to capital account and allows
amortization deductions of such capitalized expenditures ratably over a 5-year period in
the case of SRE expenditures attributable to domestic research, or a 15-year period in
the case of SRE expenditures attributable to foreign research, beginning with the
midpoint of the taxable year in which such expenditures are paid or incurred. Section
13206(a) of the TCJA also made other amendments to former § 174, including
amendments to treat any amount paid or incurred in connection with the development of
any software as an SRE expenditure and to prevent the accelerated recovery of

3
unamortized SRE expenditures on account of the disposition, retirement, or
abandonment of property with respect to which such expenditures were paid or
incurred. For additional background on former § 174 and the TCJA amendments to
former § 174, see section 2 of Notice 2023-63.
(2) Section 13206(b) of the TCJA requires taxpayers to treat the amendments
made by section 13206(a) of the TCJA as a change in method of accounting for
purposes of § 481 that is (i) initiated by the taxpayer, (ii) made with the consent of the
Secretary of the Treasury or her delegate, and (iii) applied on a cut-off basis to SRE
expenditures paid or incurred in taxable years beginning after December 31, 2021.
Thus, no adjustments under § 481(a) are required or permitted with respect to research
or experimental expenditures paid or incurred in taxable years beginning before January
1, 2022.
.03 Procedural guidance under Rev. Proc. 2023-11.

On December 29, 2022, the Department of the Treasury (Treasury Department)
and the Internal Revenue Service (IRS) issued Rev. Proc. 2023-11, 2023-3 I.R.B. 417,
modifying and superseding Rev. Proc. 2023-8, 2023-3 I.R.B. 407, to provide procedures
to obtain automatic consent to change methods of accounting for SRE expenditures to
comply with § 174. The change in method of accounting provided by Rev. Proc. 2023-
11 was subsequently included in section 7.02 of Rev. Proc. 2023-24, 2023-28 I.R.B.
1207.
.04 Interim guidance under Notice 2023-63, as modified by Notice 2024-12.

(1) Notice 2023-63 was issued on September 8, 2023, to announce that the
Treasury Department and the IRS intend to issue proposed regulations addressing

4
(1) the capitalization and amortization of SRE expenditures under § 174, (2) the
treatment of SRE expenditures under § 460, and (3) the application of § 482 to cost
sharing arrangements involving SRE expenditures. Sections 3 through 9 of Notice
2023-63 provide interim guidance regarding issues intended to be addressed by
forthcoming proposed regulations.
(2) Notice 2024-12, 2024-5 I.R.B. 616, was released on December 22, 2023, and
published on January 19, 2024, to provide additional interim guidance to clarify and
modify Notice 2023-63 regarding (1) the treatment of costs paid or incurred by a
research provider for research provided under contract, (2) the requirement that a
taxpayer that chooses to rely on any of the rules described in Notice 2023-63 must rely
on all the rules described in Notice 2023-63, and (3) the obsoletion of section 5 of Rev.
Proc. 2000-50, 2000-1 C.B. 601.
.05 Procedural guidance under Rev. Proc. 2024-9.
(1) Revenue Procedure 2024-9, 2024-5 I.R.B. 628, was released on December 22,
2023, and published on January 19, 2024, to provide procedures for taxpayers to obtain
automatic consent to change methods of accounting for expenditures paid or incurred in
taxable years beginning after December 31, 2021, to comply with § 174 or to rely on
interim guidance under §§ 174 and 460 provided in Notice 2023-63, as modified by
Notice 2024-12. The change in method of accounting for § 174 provided in section 3 of
Rev. Proc. 2024-9 modified section 7.02 of Rev. Proc. 2023-24. Rev. Proc. 2023-24
was subsequently superseded in part by Rev. Proc. 2024-23. Rev. Proc. 2024-23
renumbered section 7.02 as section 7.01 and removed former section 7.01 as obsolete.
(2) Section 7.01(5)(a) of Rev. Proc. 2024-23 waives the eligibility rules in sections

5
5.01(1)(d) (regarding changes made in the final year of a trade or business) and
5.01(1)(f) (regarding changes made in the previous 5 years for the same item) of Rev.
Proc. 2015-13 for a change described in section 7.01(1)(a) of Rev. Proc. 2024-23 for
the taxpayer’s first or second taxable year beginning after December 31, 2021.
(3) Section 7.01(5)(b) of Rev. Proc. 2024-23 provides that a taxpayer may make a
change described in section 7.01(1)(a) of Rev. Proc. 2024-23 for its second taxable
year beginning after December 31, 2021, regardless of whether the taxpayer made a
change for the same item for its first taxable year beginning after December 31, 2021.
(4) Section 7.01(6) of Rev. Proc. 2024-23 provides that a taxpayer does not
receive audit protection under section 8.01 of Rev. Proc. 2015-13 for a change under
section 7.01(1)(a) of Rev. Proc. 2024-23 in the second taxable year beginning after
December 31, 2021, with respect to expenditures paid or incurred in the first taxable
year beginning after December 31, 2021, if the taxpayer did not change its method of
accounting under section 7.01(1)(a) in an effort to comply with § 174 for the first taxable
year beginning after December 31, 2021.
.06 Changing methods of accounting under section 446(e).
(1) Except as otherwise expressly provided in the Code and the regulations
thereunder, § 446(e) and § 1.446-1(e)(2) require a taxpayer to secure the consent of the
Commissioner before changing a method of accounting for Federal income tax
purposes. Section 1.446-1(e)(3)(i) states, in part, that except as otherwise provided
under the authority of § 1.446-1(e)(3)(ii), to secure the Commissioner’s consent to a
taxpayer’s change in method of accounting the taxpayer generally must file a Form
3115, Application for Change in Accounting Method, with the Commissioner during the

6
taxable year in which the taxpayer desires to make the change in method of accounting.
Section 1.446-1(e)(3)(ii) authorizes the Commissioner to prescribe administrative
procedures under which taxpayers will be permitted to change their method of
accounting. The administrative procedures will prescribe those terms and conditions
necessary to obtain the Commissioner’s consent to effect the change and to prevent
amounts from being duplicated or omitted.
(2) Rev. Proc. 2015-13, 2015-5 I.R.B. 419, as clarified and modified by Rev. Proc.
2015-33, 2015-24 I.R.B. 1067, and as modified by Rev. Proc. 2021-34, 2021-35 I.R.B.
337, Rev. Proc. 2021-26, 2021-22 I.R.B. 1163, Rev. Proc. 2017-59, 2017-48 I.R.B. 543,
and section 17.02(b) and (c) of Rev. Proc. 2016-1, 2016-1 I.R.B. 1, sets forth the
general administrative procedures by which a taxpayer may obtain the automatic
consent of the Commissioner to change a method of accounting described in the List of
Automatic Changes. Rev. Proc. 2024-23 contains the current List of Automatic
Changes.
(3) A change in a taxpayer’s treatment of expenditures paid or incurred in taxable
years beginning after December 31, 2021, to comply with § 174 or to rely on the interim
guidance in sections 3 through 7 of Notice 2023-63 is generally a change in method of
accounting to which §§ 446(e) and 481, and the corresponding regulations, apply. A
taxpayer that changes its method of accounting to comply with § 174 or to rely on the
interim guidance in sections 3 through 7 of Notice 2023-63 must use the accounting
method change procedures in Rev. Proc. 2015-13 or its successor. Section 3 of this
revenue procedure modifies the eligibility rules and limited audit protection rules in
section 7.01 of Rev. Proc. 2024-23 to allow taxpayers to obtain automatic consent to

7
change their method of accounting to comply with § 174 or to rely on the interim
guidance provided in sections 3 through 7 of Notice 2023-63 for taxable years beginning
after December 31, 2021.
(4) Specifically, the Treasury Department and the IRS are aware that certain
taxpayers may not be eligible to file automatic changes in methods of accounting under
section 7.01 of Rev. Proc. 2024-23 for a taxable year beginning in 2022 or a taxable
year beginning in 2023 if the taxpayer had one or multiple short taxable years during
2022 or 2023. This is because the waiver of the eligibility rules in section 5.01(1)(d) and
(f) of Rev. Proc. 2015-13 apply only to a taxpayer’s first or second taxable year
beginning after December 31, 2021. Therefore, the procedures in section 3 of this
revenue procedure modify the eligibility rules in section 7.01(5)(a) of Rev. Proc. 2024-23
to provide that the eligibility rules in section 5.01(1)(d) and (f) of Rev. Proc. 2015-13 do
not apply to a change described in section 7.01(1)(a) of Rev. Proc. 2024-23 made by a
taxpayer for any taxable year beginning in 2022 or 2023. The procedures in section 3
of this revenue procedure also modify the rules for changes made in successive taxable
years in section 7.01(5)(b) of Rev. Proc. 2024-23 to provide that a taxpayer may make a
change described in section 7.01(1)(a) of Rev. Proc. 2024-23 for a taxable year
beginning in 2022 or 2023, regardless of whether the taxpayer made a change for the
same item for any previous taxable year beginning in 2022 or 2023. Finally, the
procedures in section 3 of this revenue procedure also modify the limited audit
protection rules in section 7.01(6) of Rev. Proc. 2024-23 to provide that a taxpayer does
not receive audit protection for a change under section 7.01(1)(a) of this revenue
procedure made for any taxable year beginning in 2022 or 2023 (other than the first

8
taxable year beginning after December 31, 2021) with respect to expenditures paid or
incurred in the first taxable year beginning after December 31, 2021, if the taxpayer did
not change its method of accounting under section 7.01(1)(a) in an effort to comply with
§ 174 for the first taxable year beginning after December 31, 2021.
SECTION 3. MODIFICATIONS TO REV. PROC. 2024-23

.01 Modification of section 7.01(5) and (6) of Rev. Proc. 2024-23. Section 7.01(5)
and (6) of Rev. Proc. 2024-23, are modified to read as follows:

this revenue procedure made by a taxpayer for any taxable year beginning in 2022 or
2023.
(b) C

beginning in 2022 or 2023, regardless of whether the taxpayer made a change for the
same item for any previous taxable year beginning in 2022 or 2023.
(6) Limited audit protection. A taxpayer does not receive audit protection under
section 8.01 of Rev. Proc. 2015-13 for the change under section 7.01(1)(a) of this
revenue procedure with respect to expenditures paid or incurred in taxable years
beginning on or before December 31, 2021. Additionally, a taxpayer does not receive
audit protection under section 8.01 of Rev. Proc. 2015-13 for a change under section
7.01(1)(a) of this revenue procedure made for any taxable year beginning in 2022 or
2023 (other than the first taxable year beginning after December 31, 2021), with respect
