Closing agreements.

Official textecfr.govlast amended Jul 27, 2026

# (a) In general.

The Commissioner may enter into a written agreement with any person relating to the liability of such person (or of the person or estate for whom he acts) in respect of any internal revenue tax for any taxable period ending prior or subsequent to the date of such agreement. A closing agreement may be entered into in any case in which there appears to be an advantage in having the case permanently and conclusively closed, or if good and sufficient reasons are shown by the taxpayer for desiring a closing agreement and it is determined by the Commissioner that the United States will sustain no disadvantage through consummation of such an agreement.

# (b)

Scope of closing agreement—(1) In general. A closing agreement may be executed even though under the agreement the taxpayer is not liable for any tax for the period to which the agreement relates. There may be a series of closing agreements relating to the tax liability for a single period.

(2) Taxable periods ended prior to date of closing agreement. Closing agreements with respect to taxable periods ended prior to the date of the agreement may relate to the total tax liability of the taxpayer or to one or more separate items affecting the tax liability of the taxpayer, as, for example, the amount of gross income, deduction for losses, depreciation, depletion, the year in which an item of income is to be included in gross income, the year in which an item of loss is to be deducted, or the value of property on a specific date. A closing agreement may also be entered into for the purpose of allowing a deficiency dividend deduction under section 547. In addition, a closing agreement constitutes a determination as defined by section 1313.

(3) Taxable periods ending subsequent to date of closing agreement. Closing agreements with respect to taxable periods ending subsequent to the date of the agreement may relate to one or more separate items affecting the tax liability of the taxpayer.

(4) Illustration. The provisions of this paragraph may be illustrated by the following example:

Example.

A owns 500 shares of stock in the XYZ Corporation which he purchased prior to March 1, 1913. A is considering selling 200 shares of such stock but is uncertain as to the basis of the stock for the purpose of computing gain. Either prior or subsequent to the sale, a closing agreement may be entered into determining the market value of such stock as of March 1, 1913, which represents the basis for determining gain if it exceeds the adjusted basis otherwise determined as of such date. Not only may the closing agreement determine the basis for computing gain on the sale of the 200 shares of stock, but such an agreement may also determine the basis (unless or until the law is changed to require the use of some other factor to determine basis) of the remaining 300 shares of stock upon which gain will be computed in a subsequent sale.

# (c) Finality.

A closing agreement which is approved within such time as may be stated in such agreement, or later agreed to, shall be final and conclusive, and, except upon a showing of fraud or malfeasance, or misrepresentation of a material fact:

(1) The case shall not be reopened as to the matters agreed upon or the agreement modified by any officer, employee, or agent of the United States, and

(2) In any suit, action, or proceeding, such agreement, or any determination, assessment, collection, payment, abatement, refund, or credit made in accordance therewith, shall not be annulled, modified, set aside, or disregarded.

However, a closing agreement with respect to a taxable period ending subsequent to the date of the agreement is subject to any change in, or modification of, the law enacted subsequent to the date of the agreement and made applicable to such taxable period, and each closing agreement shall so recite.

# (d)

Procedure with respect to closing agreements—(1) Submission of request. A request for a closing agreement which relates to a prior taxable period may be submitted at any time before a case with respect to the tax liability involved is docketed in the Tax Court of the United States. All closing agreements shall be executed on forms prescribed by the Internal Revenue Service. The procedure with respect to requests for closing agreements shall be under such rules as may be prescribed from time to time by the Commissioner in accordance with the regulations under this section.

(2) Collection, credit, or refund. Any tax or deficiency in tax determined pursuant to a closing agreement shall be assessed and collected, and any overpayment determined pursuant thereto shall be credited or refunded, in accordance with the applicable provisions of law.
