26 CFR 1.441-1 - Period for computation of taxable income.
(a)Computation of taxable income -
(1)In general. Taxable income must be computed and a return must be made for a period known as the taxable year. For rules relating to methods of accounting, the taxable year for which items of gross income are included and deductions are taken, inventories, and adjustments, see parts II and III (section 446 and following), subchapter E, chapter 1 of the Internal Revenue Code, and the regulations thereunder.
(2)Length of taxable year. Except as otherwise provided in the Internal Revenue Code and the regulations thereunder (e.g., § 1.441-2 regarding 52-53-week taxable years), a taxable year may not cover a period of more than 12 calendar months.
(1)Taxable year. Taxable year means -
(i) The period for which a return is made, if a return is made for a period of less than 12 months (short period). See section 443 and the regulations thereunder;
(iii) Except as provided in paragraphs (b)(1)(i) and (ii) of this section, the taxpayer's annual accounting period (as defined in paragraph (b)(3) of this section), if it is a calendar year or a fiscal year; or
(iv) Except as provided in paragraphs (b)(1)(i) and (ii) of this section, the calendar year, if the taxpayer keeps no books, does not have an annual accounting period, or has an annual accounting period that does not qualify as a fiscal year.
(2)Required taxable year -
(i)In general. Certain taxpayers must use the particular taxable year that is required under the Internal Revenue Code and the regulations thereunder (the required taxable year). For example, the required taxable year is -
(A)52-53-week taxable years. Certain taxpayers may elect to use a 52-53-week taxable year that ends with reference to their required taxable year. See, for example, §§ 1.441-3 (PSCs), 1.706-1 (partnerships), 1.1378-1 (S corporations), and 1.1502-76(a)(1) (members of a consolidated group).
(B)Partnerships, S corporations, and PSCs. A partnership, S corporation, or PSC may use a taxable year other than its required taxable year if the taxpayer elects to use a taxable year other than its required taxable year under section 444, elects a 52-53-week taxable year that ends with reference to its required taxable year as provided in paragraph (b)(2)(ii)(A) of this section or to a taxable year elected under section 444, or establishes a business purpose to the satisfaction of the Commissioner under section 442 (such as a grandfathered fiscal year).
(C)Specified foreign corporations. A specified foreign corporation (as defined in section 898(b)) may use a taxable year other than its required taxable year if it elects a 52-53-week taxable year that ends with reference to its required taxable year as provided in paragraph (b)(2)(ii)(A) of this section or makes a one-month deferral election under section 898(c)(1)(B).
(5)Fiscal year -
(i)Definition. Fiscal year means -
(A) A period of 12 consecutive months ending on the last day of any month other than December; or
(6)Grandfathered fiscal year. Grandfathered fiscal year means a fiscal year (other than a year that resulted in a three month or less deferral of income) that a partnership or an S corporation received permission to use on or after July 1, 1974, by a letter ruling (i.e., not by automatic approval).
(7)Books. Books include the taxpayer's regular books of account and such other records and data as may be necessary to support the entries on the taxpayer's books and on the taxpayer's return, as for example, a reconciliation of any difference between such books and the taxpayer's return. Records that are sufficient to reflect income adequately and clearly on the basis of an annual accounting period will be regarded as the keeping of books. See section 6001 and the regulations thereunder for rules relating to the keeping of books and records.
(8)Taxpayer. Taxpayer has the same meaning as the term person as defined in section 7701(a)(1) (e.g., an individual, trust, estate, partnership, association, or corporation) rather than the meaning of the term taxpayer as defined in section 7701(a)(14) (any person subject to tax).
(c)Adoption of taxable year -
(1)In general. Except as provided in paragraph (c)(2) of this section, a new taxpayer may adopt any taxable year that satisfies the requirements of section 441 and the regulations thereunder without the approval of the Commissioner. A taxable year of a new taxpayer is adopted by filing its first Federal income tax return using that taxable year. The filing of an application for automatic extension of time to file a Federal income tax return (e.g., Form 7004, “Application for Automatic Extension of Time to File Corporation Income Tax Return”), the filing of an application for an employer identification number (i.e., Form SS-4, “Application for Employer Identification Number”), or the payment of estimated taxes, for a particular taxable year do not constitute an adoption of that taxable year.
(2)Approval required -
(i)Taxpayers with required taxable years. A newly-formed partnership, S corporation, or PSC that wants to adopt a taxable year other than its required taxable year, a taxable year elected under section 444, or a 52-53-week taxable year that ends with reference to its required taxable year or a taxable year elected under section 444 must establish a business purpose and obtain the approval of the Commissioner under section 442.
(ii)Taxpayers without books. A taxpayer that must use a calendar year under section 441(g) and paragraph (f) of this section may not adopt a fiscal year without obtaining the approval of the Commissioner.
(d)Retention of taxable year. In certain cases, a partnership, S corporation, electing S corporation, or PSC will be required to change its taxable year unless it obtains the approval of the Commissioner under section 442, or makes an election under section 444, to retain its current taxable year. For example, a corporation using a June 30 fiscal year that either becomes a PSC or elects to be an S corporation and, as a result, is required to use the calendar year under section 441(i) or 1378, respectively, must obtain the approval of the Commissioner to retain its current fiscal year. Similarly, a partnership using a taxable year that corresponds to its required taxable year must obtain the approval of the Commissioner to retain such taxable year if its required taxable year changes as a result of a change in ownership. However, a partnership that previously established a business purpose to the satisfaction of the Commissioner to use a taxable year is not required to obtain the approval of the Commissioner if its required taxable year changes as a result of a change in ownership.
(e)Change of taxable year. Once a taxpayer has adopted a taxable year, such taxable year must be used in computing taxable income and making returns for all subsequent years unless the taxpayer obtains approval from the Commissioner to make a change or the taxpayer is otherwise authorized to change without the approval of the Commissioner under the Internal Revenue Code (e.g., section 444 or 859) or the regulations thereunder.
(f)Obtaining approval of the Commissioner or making a section 444 election. See § 1.442-1(b) for procedures for obtaining approval of the Commissioner (automatically or otherwise) to adopt, change, or retain an annual accounting period. See §§ 1.444-1T and 1.444-2T for qualifications, and 1.444-3T for procedures, for making an election under section 444.
