PART III. PROCEDURES FOR LETTER RULING REQUESTS

SECTION 29. WHAT

Internal Revenue Bulletin 2018-1 · 2026-10-03 edition · updated 2026-10-04 · United States

EFFECT WILL A LETTER RULING HAVE?

Has same effect as a determination letter

Will not apply to another taxpayer

Will be used by the Service in examining the taxpayer’s return

taxpayer actually intends to make a request, if the request involves a matter on which a letter ruling is ordinarily issued, and at the discretion of Employee Plans Rulings and Agreements and as time permits. For example, a pre-submission conference will not be held on an issue if, at the time the pre-submission conference is requested, the identical issue is involved in the taxpayer’s return for an earlier period and that issue is being examined. See section 24 of this revenue procedure. Generally, the taxpayer will be asked to provide a statement of whether the issue is an issue on which a letter ruling is ordinarily issued and a draft of the letter ruling request or other detailed written statement of the proposed transaction, issue(s), and legal analysis before the pre-submission conference. If the taxpayer’s representative will attend the pre-submission conference, a power of attorney form is required. A Form 2848, Power of Attorney and Declaration of Representative, must be used to provide the representative’s authorization.

Any discussion of substantive issues at a pre-submission conference is advisory only, is not binding on the Service, and cannot be relied upon as a basis for obtaining retroactive relief under the provisions of § 7805(b). See section 3.06(2) of this revenue procedure. A letter ruling request submitted following a pre-submission conference will not necessarily be assigned to the group that held the pre-submission conference.

.08 A taxpayer may request that a conference of right be held by telephone. This request may occur, for example, if a taxpayer wants a conference of right but believes that the issue involved does not warrant incurring the expense of traveling to Washington, DC. If a taxpayer makes such a request, the group manager will decide if it is appropriate in the particular case to hold the conference of right by telephone. If the request is approved by the group manager, the taxpayer will be advised when to call the Employee Plans Rulings and Agreements representatives (not a toll-free call).

.01 Except as described in this section 29, a letter ruling issued by Employee Plans Rulings and Agreements has the same effect as a determination letter ruling issued to a taxpayer under Part II of this revenue procedure.

.02 A taxpayer may not rely on a letter ruling issued to another taxpayer. See § 6110(k)(3).

.03 When determining a taxpayer’s liability, the Service must ascertain whether—

(1) the conclusions stated in the letter ruling are properly reflected in the return;

(2) the representations upon which the letter ruling was based reflected an accurate statement of the material facts;

(3) the transaction was carried out substantially as proposed; and

(4) there has been any change in the law that applies to the period during which the transaction or continuing series of transactions were consummated.

Bulletin No. 2018–1 209 January 2, 2018

May be revoked or modified if found to be in error

Letter ruling revoked or modified based on material change in facts applied retroactively

Not otherwise generally revoked or modified retroactively

.04 A letter ruling found to be in error or not in accord with the current views of the Service may be revoked or modified, unless it was part of a closing agreement as described in section 3.03 of this revenue procedure. If a letter ruling is revoked or modified, the revocation or modification applies to all years open under the period of limitation unless a request to limit the retroactive effect of a revocation or modification has been granted under § 7805(b). A request to limit the retroactive revocation or modification of a letter ruling issued by Employee Plans Rulings and Agreements should be submitted to the agent or specialist assigned to the case, and should otherwise follow the procedures described in section 23.08.

A letter ruling may be revoked or modified by—

(1) a letter giving notice of revocation or modification to the taxpayer to whom the letter ruling was issued;

(2) the enactment of legislation or ratification of a tax treaty;

(3) a decision of the United States Supreme Court;

(4) the issuance of temporary or final regulations; or

(5) the issuance of a revenue ruling, revenue procedure, notice, or other statement published in the Internal Revenue Bulletin.

Consistent with these provisions, if a letter ruling relates to a continuing action or a series of actions, it will ordinarily be applied until any one of the events described above occurs or until the letter ruling is specifically withdrawn by the Service.

Publication of a notice of proposed rulemaking will not affect the application of any letter ruling issued under this revenue procedure.

If a letter ruling is revoked or modified by a letter to the taxpayer, the letter will state whether the revocation or modification is retroactive. If a letter ruling is revoked or modified by the issuance of final or temporary regulations or by the publication of a revenue ruling, revenue procedure, notice, or other statement in the Internal Revenue Bulletin, the document may contain a statement as to its retroactive effect on letter rulings.

.05 The revocation or modification of a letter ruling will be applied retroactively to the taxpayer for whom the letter ruling was issued or to a taxpayer whose tax liability was directly involved in the letter ruling if—

(1) there was a misstatement or omission of controlling facts;

(2) the facts at the time of the transaction are materially different from the controlling facts on which the letter ruling was based; or

(3) the transaction involves a continuing action or series of actions and the controlling facts change during the course of the transaction.

.06 If the revocation or modification of a letter ruling occurs, for reasons other than a change in facts as described in section 29.05 of this revenue procedure, the revocation or modification

January 2, 2018 210 Bulletin No. 2018–1

Retroactive effect of revocation or modification applied to a particular transaction

Retroactive effect of revocation or modification applied to a continuing action or series of actions

May be retroactively revoked or modified if the transaction is completed without reliance on the letter ruling
