    CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY 
                               (CONTINUED)
 
PART 1_INCOME TAXES--Table of Contents
 
Sec. 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., Sec. 1.441-
2 regarding 52-53-week taxable years), a taxable year may not cover a 
period of more than 12 calendar months.
    (b) General rules and definitions. The general rules and definitions 
in this

[[Page 10]]

paragraph (b) apply for purposes of sections 441 and 442 and the 
regulations thereunder.
    (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;
    (ii) Except as provided in paragraph (b)(1)(i) of this section, the 
taxpayer's required taxable year (as defined in paragraph (b)(2) of this 
section), if applicable;
    (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) In the case of a foreign sales corporation or domestic 
international sales corporation, the taxable year determined under 
section 441(h) and Sec. 1.921-1T(a)(11), (b)(4), and (b)(6);
    (B) In the case of a personal service corporation (PSC), the taxable 
year determined under section 441(i) and Sec. 1.441-3;
    (C) In the case of a nuclear decommissioning fund, the taxable year 
determined under Sec. 1.468A-4(c)(1);
    (D) In the case of a designated settlement fund or a qualified 
settlement fund, the taxable year determined under Sec. 1.468B-2(j);
    (E) In the case of a common trust fund, the taxable year determined 
under section 584(i);
    (F) In the case of certain trusts, the taxable year determined under 
section 644;
    (G) In the case of a partnership, the taxable year determined under 
section 706 and Sec. 1.706-1;
    (H) In the case of an insurance company, the taxable year determined 
under section 843 and Sec. 1.1502-76(a)(2);
    (I) In the case of a real estate investment trust, the taxable year 
determined under section 859;
    (J) In the case of a real estate mortgage investment conduit, the 
taxable year determined under section 860D(a)(5) and Sec. 1.860D-
1(b)(6);
    (K) In the case of a specified foreign corporation, the taxable year 
determined under section 898(c)(1)(A);
    (L) In the case of an S corporation, the taxable year determined 
under section 1378 and Sec. 1.1378-1; or
    (M) In the case of a member of an affiliated group that makes a 
consolidated return, the taxable year determined under Sec. 1.1502-76.
    (ii) Exceptions. Notwithstanding paragraph (b)(2)(i) of this 
section, the following taxpayers may have a taxable year other than 
their required taxable year:
    (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, Sec. Sec. 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).

    (3) Annual accounting period. Annual accounting period means the 
annual period (calendar year or fiscal year) on the basis of which the 
taxpayer regularly computes its income in keeping its books.
    (4) Calendar year. Calendar year means a period of 12 consecutive 
months ending on December 31. A taxpayer who has not established a 
fiscal year must make its return on the basis of a calendar year.
    (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
    (B) A 52-53-week taxable year, if such period has been elected by 
the taxpayer. See Sec. 1.441-2.
    (ii) Recognition. A fiscal year will be recognized only if the books 
of the taxpayer are kept in accordance with such fiscal year.
    (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

[[Page 12]]

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 Sec. 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 Sec. Sec. 1.444-1T and 1.444-2T 
for qualifications, and 1.444-3T for procedures, for making an election 
under section 444.
