(a) In general.

(1) If a taxpayer has not adopted the method provided in section 174(a) of treating research or experimental expenditures paid or incurred by him in connection with his trade or business as currently deductible expenses, he may, for any taxable year beginning after December 31, 1953, elect to treat such expenditures as deferred expenses under section 174(b), subject to the limitations of subparagraph (2) of this paragraph. If a taxpayer has adopted the method of treating such expenditures as expenses under section 174(a), he may not elect to defer and amortize any such expenditures unless permission to do so is granted under section 174(a)(3). See paragraph (b) of this section.

(2) The election to treat research or experimental expenditures as deferred expenses under section 174(b) applies only to those expenditures which are chargeable to capital account but which are not chargeable to property of a character subject to an allowance for depreciation or depletion under section 167 or 611, respectively. Thus, the election under section 174(b) applies only if the property resulting from the research or experimental expenditures has no determinable useful life. If the property resulting from the expenditures has a determinable useful life, section 174(b) is not applicable, and the capitalized expenditures must be amortized or depreciated over the determinable useful life. Amounts treated as deferred expenses are properly chargeable to capital account for purposes of section 1016(a)(1), relating to adjustments to basis of property. See section 1016(a)(14). See section 174(c) and paragraph (b)(1) of §1.174-2 for treatment of expenditures for the acquisition or improvement of land or of depreciable or depletable property to be used in connection with the research or experimentation.

(3) Expenditures which are treated as deferred expenses under section 174(b) are allowable as a deduction ratably over a period of not less than 60 consecutive months beginning with the month in which the taxpayer first realizes benefits from the expenditures. The length of the period shall be selected by the taxpayer at the time he makes the election to defer the expenditures. If a taxpayer has two or more separate projects, he may select a different amortization period for each project. In the absence of a showing to the contrary, the taxpayer will be deemed to have begun to realize benefits from the deferred expenditures in the month in which the taxpayer first puts the process, formula, invention, or similar property to which the expenditures relate to an income-producing use. See section 1016(a)(14) for adjustments to basis of property for amounts allowed as deductions under section 174(b) and this section. See section 165 and the regulations thereunder for rules relating to the treatment of losses resulting from abandonment.

(4) If expenditures which the taxpayer has elected to defer and deduct ratably over a period of time in accordance with section 174(b) result in the development of depreciable property, deductions for the unrecovered expenditures, beginning with the time the asset becomes depreciable in character, shall be determined under section 167 (relating to depreciation) and the regulations thereunder. For example, for the taxable year 1954, A, who reports his income on the basis of a calendar year, elects to defer and deduct ratably over a period of 60 months research and experimental expenditures made in connection with a particular project. In 1956, the total of the deferred expenditures amounts to $60,000. At that time, A has developed a process which he seeks to patent. On July 1, 1956, A first realized benefits from the marketing of products resulting from this process. Therefore, the expenditures deferred are deductible ratably over the 60-month period beginning with July 1, 1956 (when A first realized benefits from the project). In his return for the year 1956. A deducted $6,000; in 1957, A deducted $12,000 ($1,000 per month). On July 1, 1958, a patent protecting his process is obtained by A. In his return for 1958, A is entitled to a deduction of $6,000, representing the amortizable portion of the deferred expenses attributable to the period prior to July 1, 1958. The balance of the unrecovered expenditures ($60,000 minus $24,000, or $36,000) is to be recovered as a depreciation deduction over the life of the patent commencing with July 1, 1958. Thus, one-half of the annual depreciation deduction based upon the useful life of the patent is also deductible for 1958 (from July 1 to December 31).

(5) The election shall be applicable to all research and experimental expenditures paid or incurred by the taxpayer or, if so limited by the taxpayer's election, to all such expenditures with respect to the particular project, subject to the limitations of subparagraph (2) of this paragraph. The election shall apply for the taxable year for which the election is made and for all subsequent taxable years, unless a change to a different treatment is authorized by the Commissioner under section 174(b)(2). See paragraph (b)(2) of this section. Likewise, the taxpayer shall adhere to the amortization period selected at the time of the election unless a different period of amortization with respect to a part or all of the expenditures is similarly authorized. However, no change in method will be permitted with respect to expenditures paid or incurred before the taxable year to which the change is to apply. In no event will the taxpayer be permitted to treat part of the expenditures with respect to a particular project as deferred expenses under section 174(b) and to adopt a different method of treating the balance of the expenditures relating to the same project for the same taxable year. The election under this section shall not apply to any expenditures paid or incurred before the taxable year for which the taxpayer makes the election.

(b) Election and change of method—(1) Election. The election under section 174(b) shall be made not later than the time (including extensions) prescribed by law for filing the return for the taxable year for which the method is to be adopted. The election shall be made by attaching a statement to the taxpayer's return for the first taxable year to which the election is applicable. The statement shall be signed by the taxpayer (or his duly authorized representative), and shall:

(i) Set forth the name and address of the taxpayer;

(ii) Designate the first taxable year to which the election is to apply;

(iii) State whether the election is intended to apply to all expenditures within the permissible scope of the election, or only to a particular project or projects, and, if the latter, include such information as will identify the project or projects as to which the election is to apply;

(iv) Set forth the amount of all research or experimental expenditures paid or incurred during the taxable year for which the election is made;

(v) Indicate the number of months (not less than 60) selected for amortization of the deferred expenses for each project; and

(vi) State that the taxpayer will make an accounting segregation in his books and records of the expenditures to which the election relates.

(2) Change to a different method or period. Application for permission to change to a different method of treating research or experimental expenditures or to a different period of amortization for deferred expenses shall be in writing and shall be addressed to the Commissioner of Internal Revenue, Attention: T:R, Washington, DC, 20224. The application shall include the name and address of the taxpayer, shall be signed by the taxpayer (or his duly authorized representative), and shall be filed not later than the end of the first taxable year in which the different method or different amortization period is to be used (unless subparagraph (3) of this paragraph, relating to extensions of time, is applicable). The application shall set forth the following information with regard to the research or experimental expenditures which are being treated under section 174(b) as deferred expenses:

(i) Total amount of research or experimental expenditures attributable to each project;

(ii) Amortization period applicable to each project; and

(iii) Unamortized expenditures attributable to each project at the beginning of the taxable year in which the application is filed.

In addition, the application shall set forth the length of the new period or periods proposed, or the new method of treatment proposed, the reasons for the proposed change, and such information as will identify the project or projects to which the expenditures affected by the change relate. If permission is granted to make the change, the taxpayer shall attach a copy of the letter granting the permission to his income tax return for the first taxable year in which the different method or period is to be effective.

(3) Special rules. If the last day prescribed by law for filing a return for any taxable year for which the deferred method provided in section 174(b) has been adopted falls before January 2, 1958, consent is hereby given for the taxpayer to change from such method and adopt a different method of treating research or experimental expenditures, provided that on or before January 2, 1958, he submits to the district director for the district in which the return was filed the information required by subparagraph (2) of this paragraph, relating to a change to a different method or period. For any taxable year for which the different method is adopted pursuant to this subparagraph, an amended return reflecting such method shall be filed on or before January 2, 1958.

(c) Example. The application of this section is illustrated by the following example:
