Computations on returns or other documents.

Official textecfr.govlast amended Jul 27, 2026

# (a) Amounts shown on forms.

To the extent permitted by any internal revenue form or instructions prescribed for use with respect to any internal revenue return, declaration, statement, other document, or supporting schedules, any amount required to be reported on such form shall be entered at the nearest whole dollar amount. The extent to which, and the conditions under which, such whole dollar amounts shall be entered on any form will be set forth in the instructions issued with respect to such form. For the purpose of the computation to the nearest dollar, a fractional part of a dollar shall be disregarded unless it amounts to one-half dollar or more, in which case the amount (determined without regard to the fractional part of a dollar) shall be increased by $1. The following illustrates the application of this paragraph:

Exact amount	To be reported as—
$18.49	$18
$18.50	19
$18.51	19

# (b)

Election not to use whole dollar amounts—(1) Method of election. Where any internal revenue form, or the instructions issued with respect to such form, provide that whole dollar amounts shall be reported, any person making a return, declaration, statement, or other document on such form may elect not to use whole dollar amounts by reporting thereon all amounts in full, including cents.

(2) Time of election. The election not to use whole dollar amounts must be made at the time of filing the return, declaration, statement, or other document. Such election may not be revoked after the time prescribed for filing such return, declaration, statement, or other document, including extensions of time granted for such filing. Such election may be made on any return, declaration, statement, or other document which is filed after the time prescribed for filing (including extensions of time), and such an election is irrevocable.

(3) Effect of election. The taxpayer's election shall be binding only on the return, declaration, statement, or other document filed for a taxable year or period, and a new election may be made on the return, declaration, statement, or other document filed for a subsequent taxable year or period. An election by either a husband or a wife not to report whole dollar amounts on a separate income tax return shall be binding on any subsequent joint return filed under the provisions of section 6013(b).

(4) Fractional part of a cent. For treatment of the fractional part of a cent in the payment of taxes, see section 6313 and § 301.6313-1.

# (c) Inapplicability to computation of amount.

The provisions of paragraph (a) of this section apply only to amounts required to be reported on a return, declaration, statement, or other document. They do not apply to items which must be taken into account in making the computations necessary to determine such amounts. For example, each item of receipt must be taken into account at its exact amount, including cents, in computing the amount of total receipts required to be reported on an income tax return or supporting schedule. It is the amount of total receipts, so computed, which is to be reported at the nearest whole dollar on the return or supporting schedule.

# (d) Effect on accounting method.

Section 6102 and this section have no effect on any authorized accounting method.
