EXPERIMENTAL EXPENDITURES (§ 174)

.01 Changes to a different method or different amortization period .

(1) Description of change . (a) This change applies to a taxpayer that wants to change the treatment of expenditures that qualify as research and

experimental expenditures under § 174. Unless otherwise stated, references to § 174 in this section 7.01 refer to § 174 as in effect prior to amendment by § 13206 of Public Law 115-97, 131 Stat. 2054 (Dec. 22, 2017), commonly referred to as the Tax Cuts and Jobs Act (TCJA).

(b) Section 174 and the regulations thereunder provide the specific rules for changing a method of accounting under § 174 for research and experimental expenditures. Under § 174, a taxpayer may treat research and experimental expenditures that are paid or incurred by the taxpayer during the taxable year in connection with the taxpayer’s trade or business as expenses under § 174(a) or as deferred expenses amortizable ratably over a period of not less than 60 months under § 174(b). Pursuant to § 1.174-1, research and experimental expenditures that are not treated as expenses or deferred expenses under § 174 must be treated as a charge to capital account. Further, § 1.174-1 provides that the expenditures to which § 174 applies may relate either to a general research program or to a particular project. Finally, §§ 1.174-3(a) and 1.1744(a)(5) provide that in no event will a taxpayer be permitted to apply one method as to part of the expenditures relative to a particular project and apply a different method to the balance of the expenditures relating to the same project for the same taxable year.

(c) If a taxpayer has not treated research and experimental expenditures as expenses under § 174(a), § 174(a)(2) (B) and § 1.174-3(b)(2) provide that the taxpayer may, with consent, adopt the expense method at any time.

(d) If a taxpayer has treated research and experimental expenditures as expenses under § 174(a), § 174(a)(3) and § 1.174-3(b)(3) provide that the taxpayer may, with consent, change to a different method of treating research and experimental expenditures.

(e) If a taxpayer has treated research and experimental expenditures as deferred expenses under § 174(b), § 174(b)(2) and § 1.174-4(b)(2) provide that the taxpayer may, with consent, change to a different method of treating research or experimental expenditures or to a different period of amortization for deferred expenses.

(2) Applicability .

This change includes a change from capitalizing specified research and experimental expenditures to inventoriable property or

depreciable property and recovering such expenditures through cost of goods sold or depreciation, respectively, to the required § 174 method. Unless otherwise stated, references to “§ 174” in this section 7.02 refer to § 174 as amended by § 13206(a) of the TCJA. Section 13206(e) of the TCJA provides that the amendments made by § 13206 of the TCJA apply to amounts paid or incurred in taxable years beginning after December 31, 2021.

(b) Section 174(a)(1) provides that in the case of a taxpayer’s specified research or experimental expenditures for any taxable year, except as provided in § 174(a) (2), no deduction is allowed for such expenditures. Section 174(a)(2) provides that the taxpayer must charge such expenditures to capital account and is allowed an amortization deduction of such expenditures ratably over the 5-year period (15year period in the case of any specified research or experimental expenditures which are attributable to foreign research within the meaning of § 41(d)(4)(F) of the Code) beginning with the midpoint of the taxable year in which such expenditures are paid or incurred. The method of accounting described in this section 7.02(1)(b) is referred to as the “required § 174 method” in this section 7.02.

(2) Applicability . This change to the required § 174 method applies to specified research or experimental expenditures (as defined in § 174(b)) paid or incurred in taxable years beginning after December 31, 2021. (3) Inapplicability . This change does not apply to:

(a) a change in the treatment of acquired, leased, or licensed computer software under Rev. Proc. 2000-50, 200052 I.R.B. 601, as modified by Rev. Proc. 2007-16, 2007-1 C.B. 358 (see section 9.01 of this revenue procedure); or (b) a change in the treatment of research or experimental expenditures under former § 174, or software development expenditures, paid or incurred in taxable years beginning before January 1, 2022 (see sections 7.01 and 9.01 of this revenue procedure).

Notwithstanding the definition of Form 3115 in section 3.07 of Rev. Proc. 2015-13, 2015-5 I.R.B. 419, the statement in lieu of a Form 3115 that is permitted under this section 7.02(4)(a)(ii) is considered a Form 3115 for purposes of the automatic consent procedures of Rev.
