Sec. 1.446-1  General rule for methods of accounting.

    (a) General rule. (1) Section 446(a) provides that taxable income 
shall be computed under the method of accounting on the basis of which a 
taxpayer regularly computes his income in keeping his books. The term 
``method of accounting'' includes not only the overall method of 
accounting of the taxpayer but also the accounting treatment of any 
item. Examples of such over-all methods are the cash receipts and 
disbursements method, an accrual

[[Page 50]]

method, combinations of such methods, and combinations of the foregoing 
with various methods provided for the accounting treatment of special 
items. These methods of accounting for special items include the 
accounting treatment prescribed for research and experimental 
expenditures, soil and water conservation expenditures, depreciation, 
net operating losses, etc. Except for deviations permitted or required 
by such special accounting treatment, taxable income shall be computed 
under the method of accounting on the basis of which the taxpayer 
regularly computes his income in keeping his books. For requirement 
respecting the adoption or change of accounting method, see section 
446(e) and paragraph (e) of this section.
    (2) It is recognized that no uniform method of accounting can be 
prescribed for all taxpayers. Each taxpayer shall adopt such forms and 
systems as are, in his judgment, best suited to his needs. However, no 
method of accounting is acceptable unless, in the opinion of the 
Commissioner, it clearly reflects income. A method of accounting which 
reflects the consistent application of generally accepted accounting 
principles in a particular trade or business in accordance with accepted 
conditions or practices in that trade or business will ordinarily be 
regarded as clearly reflecting income, provided all items of gross 
income and expense are treated consistently from year to year.
    (3) Items of gross income and expenditures which are elements in the 
computation of taxable income need not be in the form of cash. It is 
sufficient that such items can be valued in terms of money. For general 
rules relating to the taxable year for inclusion of income and for 
taking deductions, see sections 451 and 461, and the regulations 
thereunder.
    (4) Each taxpayer is required to make a return of his taxable income 
for each taxable year and must maintain such accounting records as will 
enable him to file a correct return. See section 6001 and the 
regulations thereunder. Accounting records include the taxpayer's 
regular books of account and such other records and data as may be 
necessary to support the entries on his books of account and on his 
return, as for example, a reconciliation of any differences between such 
books and his return. The following are among the essential features 
that must be considered in maintaining such records:
    (i) In all cases in which the production, purchase, or sale of 
merchandise of any kind is an income-producing factor, merchandise on 
hand (including finished goods, work in process, raw materials, and 
supplies) at the beginning and end of the year shall be taken into 
account in computing the taxable income of the year. (For rules relating 
to computation of inventories, see section 263A, 471, and 472 and the 
regulations thereunder.)
    (ii) Expenditures made during the year shall be properly classified 
as between capital and expense. For example, expenditures for such items 
as plant and equipment, which have a useful life extending substantially 
beyond the taxable year, shall be charged to a capital account and not 
to an expense account.
    (iii) In any case in which there is allowable with respect to an 
asset a deduction for depreciation, amortization, or depletion, any 
expenditures (other than ordinary repairs) made to restore the asset or 
prolong its useful life shall be added to the asset account or charged 
against the appropriate reserve.
    (b) Exceptions. (1) If the taxpayer does not regularly employ a 
method of accounting which clearly reflects his income, the computation 
of taxable income shall be made in a manner which, in the opinion of the 
Commissioner, does clearly reflect income.
    (2) A taxpayer whose sole source of income is wages need not keep 
formal books in order to have an accounting method. Tax returns, copies 
thereof, or other records may be sufficient to establish the use of the 
method of accounting used in the preparation of the taxpayer's income 
tax returns.
    (c) Permissible methods--(1) In general. Subject to the provisions 
of paragraphs (a) and (b) of this section, a taxpayer may compute his 
taxable income under any of the following methods of accounting:
    (i) Cash receipts and disbursements method. Generally, under the 
cash receipts and disbursements method in

[[Page 51]]

the computation of taxable income, all items which constitute gross 
income (whether in the form of cash, property, or services) are to be 
included for the taxable year in which actually or constructively 
received. Expenditures are to be deducted for the taxable year in which 
actually made. For rules relating to constructive receipt, see Sec. 
1.451-2. For treatment of an expenditure attributable to more than one 
taxable year, see section 461(a) and paragraph (a)(1) of Sec. 1.461-1.
    (ii) Accrual method. (A) Generally, under an accrual method, income 
is to be included for the taxable year when all the events have occurred 
that fix the right to receive the income and the amount of the income 
can be determined with reasonable accuracy. Under such a method, a 
liability is incurred, and generally is taken into account for Federal 
income tax purposes, in the taxable year in which all the events have 
occurred that establish the fact of the liability, the amount of the 
liability can be determined with reasonable accuracy, and economic 
performance has occurred with respect to the liability. (See paragraph 
(a)(2)(iii)(A) of Sec. 1.461-1 for examples of liabilities that may not 
be taken into account until after the taxable year incurred, and see 
Sec. Sec. 1.461-4 through 1.461-6 for rules relating to economic 
performance.) Applicable provisions of the Code, the Income Tax 
Regulations, and other guidance published by the Secretary prescribe the 
manner in which a liability that has been incurred is taken into 
account. For example, section 162 provides that a deductible liability 
generally is taken into account in the taxable year incurred through a 
deduction from gross income. As a further example, under section 263 or 
263A, a liability that relates to the creation of an asset having a 
useful life extending substantially beyond the close of the taxable year 
is taken into account in the taxable year incurred through 
capitalization (within the meaning of Sec. 1.263A-1(c)(3)) and may 
later affect the computation of taxable income through depreciation or 
otherwise over a period including subsequent taxable years, in 
accordance with applicable Internal Revenue Code sections and related 
guidance.
    (B) The term ``liability'' includes any item allowable as a 
deduction, cost, or expense for Federal income tax purposes. In addition 
to allowable deductions, the term includes any amount otherwise 
allowable as a capitalized cost, as a cost taken into account in 
computing cost of goods sold, as a cost allocable to a long-term 
contract, or as any other cost or expense. Thus, for example, an amount 
that a taxpayer expends or will expend for capital improvements to 
property must be incurred before the taxpayer may take the amount into 
account in computing its basis in the property. The term ``liability'' 
is not limited to items for which a legal obligation to pay exists at 
the time of payment. Thus, for example, amounts prepaid for goods or 
services and amounts paid without a legal obligation to do so may not be 
taken into account by an accrual basis taxpayer any earlier than the 
taxable year in which those amounts are incurred.
    (C) No method of accounting is acceptable unless, in the opinion of 
the Commissioner, it clearly reflects income. The method used by the 
taxpayer in determining when income is to be accounted for will 
generally be acceptable if it accords with generally accepted accounting 
principles, is consistently used by the taxpayer from year to year, and 
is consistent with the Income Tax Regulations. For example, a taxpayer 
engaged in a manufacturing business may account for sales of the 
taxpayer's product when the goods are shipped, when the product is 
delivered or accepted, or when title to the goods passes to the 
customers, whether or not billed, depending on the method regularly 
employed in keeping the taxpayer's books.
    (iii) Other permissible methods. Special methods of accounting are 
described elsewhere in chapter 1 of the Code and the regulations 
thereunder. For example, see the following sections and the regulations 
thereunder: Sections 61 and 162, relating to the crop method of 
accounting; section 453, relating to the installment method; section 
460, relating to the long-term contract methods. In addition, special 
methods of accounting for particular items of income and expense are 
provided under

[[Page 52]]

other sections of chapter 1. For example, see section 174, relating to 
research and experimental expenditures, and section 175, relating to 
soil and water conservation expenditures.
    (iv) Combinations of the foregoing methods. (a) In accordance with 
the following rules, any combination of the foregoing methods of 
accounting will be permitted in connection with a trade or business if 
such combination clearly reflects income and is consistently used. Where 
a combination of methods of accounting includes any special methods, 
such as those referred to in subdivision (iii) of this subparagraph, the 
taxpayer must comply with the requirements relating to such special 
methods. A taxpayer using an accrual method of accounting with respect 
to purchases and sales may use the cash method in computing all other 
items of income and expense. However, a taxpayer who uses the cash 
method of accounting in computing gross income from his trade or 
business shall use the cash method in computing expenses of such trade 
or business. Similarly, a taxpayer who uses an accrual method of 
accounting in computing business expenses shall use an accrual method in 
computing items affecting gross income from his trade or business.
    (b) A taxpayer using one method of accounting in computing items of 
income and deductions of his trade or business may compute other items 
of income and deductions not connected with his trade or business under 
a different method of accounting.
    (2) Special rules. (i) In any case in which it is necessary to use 
an inventory the accrual method of accounting must be used with regard 
to purchases and sales unless otherwise authorized under subdivision 
(ii) of this subparagraph.
    (ii) No method of accounting will be regarded as clearly reflecting 
income unless all items of gross profit and deductions are treated with 
consistency from year to year. The Commissioner may authorize a taxpayer 
to adopt or change to a method of accounting permitted by this chapter 
although the method is not specifically described in the regulations in 
this part if, in the opinion of the Commissioner, income is clearly 
reflected by the use of such method. Further, the Commissioner may 
authorize a taxpayer to continue the use of a method of accounting 
consistently used by the taxpayer, even though not specifically 
authorized by the regulations in this part, if, in the opinion of the 
Commissioner, income is clearly reflected by the use of such method. See 
section 446(a) and paragraph (a) of this section, which require that 
taxable income shall be computed under the method of accounting on the 
basis of which the taxpayer regularly computes his income in keeping his 
books, and section 446(e) and paragraph (e) of this section, which 
require the prior approval of the Commissioner in the case of changes in 
accounting method.
    (iii) The timing rules of Sec. 1.1502-13 are a method of accounting 
for intercompany transactions (as defined in Sec. 1.1502-13(b)(1)(i)), 
to be applied by each member of a consolidated group in addition to the 
member's other methods of accounting. See Sec. 1.1502-13(a)(3)(i). This 
paragraph (c)(2)(iii) is applicable to consolidated return years 
beginning on or after November 7, 2001.
    (d) Taxpayer engaged in more than one business. (1) Where a taxpayer 
has two or more separate and distinct trades or businesses, a different 
method of accounting may be used for each trade or business, provided 
the method used for each trade or business clearly reflects the income 
of that particular trade or business. For example, a taxpayer may 
account for the operations of a personal service business on the cash 
receipts and disbursements method and of a manufacturing business on an 
accrual method, provided such businesses are separate and distinct and 
the methods used for each clearly reflect income. The method first used 
in accounting for business income and deductions in connection with each 
trade or business, as evidenced in the taxpayer's income tax return in 
which such income or deductions are first reported, must be consistently 
followed thereafter.
    (2) No trade or business will be considered separate and distinct 
for purposes of this paragraph unless a complete and separable set of 
books and

[[Page 53]]

records is kept for such trade or business.
    (3) If, by reason of maintaining different methods of accounting, 
there is a creation or shifting of profits or losses between the trades 
or businesses of the taxpayer (for example, through inventory 
adjustments, sales, purchases, or expenses) so that income of the 
taxpayer is not clearly reflected, the trades or businesses of the 
taxpayer will not be considered to be separate and distinct.
    (e) Requirement respecting the adoption or change of accounting 
method. (1) A taxpayer filing his first return may adopt any permissible 
method of accounting in computing taxable income for the taxable year 
covered by such return. See section 446(c) and paragraph (c) of this 
section for permissible methods. Moreover, a taxpayer may adopt any 
permissible method of accounting in connection with each separate and 
distinct trade or business, the income from which is reported for the 
first time. See section 446(d) and paragraph (d) of this section. See 
also section 446(a) and paragraph (a) of this section.
    (2)(i) Except as otherwise expressly provided in chapter 1 of the 
Code and the regulations thereunder, a taxpayer who changes the method 
of accounting employed in keeping his books shall, before computing his 
income upon such new method for purposes of taxation, secure the consent 
of the Commissioner. Consent must be secured whether or not such method 
is proper or is permitted under the Internal Revenue Code or the 
regulations thereunder.
    (ii) (a) [Reserved]. For further guidance, see Sec. 1.446-
1T(e)(2)(ii)(a).
    (b) [Reserved]. For further guidance, see Sec. 1.446-
1T(e)(2)(ii)(b).
    (c) A change in an overall plan or system of identifying or valuing 
items in inventory is a change in method of accounting. Also a change in 
the treatment of any material item used in the overall plan for 
identifying or valuing items in inventory is a change in method of 
accounting.
    (d) Changes involving depreciable or amortizable assets. [Reserved]. 
For further guidance, see Sec. 1.446-1T(e)(2)(ii)(d).
    (iii) Examples. [Reserved]. For further guidance, see Sec. 1.446-
1T(e)(2)(iii).
    (3)(i) Except as otherwise provided under the authority of paragraph 
(e)(3)(ii) of this section, to secure the Commissioner's consent to a 
taxpayer's change in method of accounting the taxpayer must file an 
application on Form 3115 with the Commissioner during the taxable year 
in which the taxpayer desires to make the change in method of 
accounting. To the extent applicable, the taxpayer must furnish all 
information requested on the Form 3115. This information includes all 
classes of items that will be treated differently under the new method 
of accounting, any amounts that will be duplicated or omitted as a 
result of the proposed change, and the taxpayer's computation of any 
adjustments necessary to prevent such duplications or omissions. The 
Commissioner may require such other information as may be necessary to 
determine whether the proposed change will be permitted. Permission to 
change a taxpayer's method of accounting will not be granted unless the 
taxpayer agrees to the Commissioner's prescribed terms and conditions 
for effecting the change, including the taxable year or years in which 
any adjustment necessary to prevent amounts from being duplicated or 
omitted is to be taken into account. See section 481 and the regulations 
thereunder, relating to certain adjustments resulting from accounting 
method changes, and section 472 and the regulations thereunder, relating 
to adjustments for changes to and from the last-in, first-out inventory 
method. For any Form 3115 filed on or after May 15, 1997, see Sec. 
1.446-1T(e)(3)(i)(B).
    (ii) Notwithstanding the provisions of paragraph (e)(3)(i) of this 
section, the Commissioner may prescribe administrative procedures under 
which taxpayers will be permitted to change their method of accounting. 
The administrative procedures shall 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. The terms and 
conditions that may be prescribed by the Commissioner may include terms 
and conditions that require the change in method of accounting to be 
effected on a cut-off basis or by an adjustment under

[[Page 54]]

section 481(a) to be taken into account in the taxable year or years 
prescribed by the Commissioner.
    (iii) This paragraph (e)(3) applies to Forms 3115 filed on or after 
December 31, 1997. For other Forms 3115, see Sec. 1.446-1(e)(3) in 
effect prior to December 31, 1997 (Sec. 1.446-1(e)(3) as contained in 
the 26 CFR part 1 edition revised as of April 1, 1997).
    (4) Effective date. [Reserved]. For further guidance, see Sec. 
1.446(e)-1T(e)(4)(i) and (ii).
