SECTION 14. HOW MAY

RETROACTIVE EFFECT BE LIMITED?

Request for relief under § 7805(b)

a TAM on behalf of the holder for the same issue addressed in the TAM involving the issuer, and the Associate office issues a TAM involving that issue and that holder.

.01 The holdings in a TAM are applied retroactively, whether they are initial holdings or they are later holdings that modify or revoke holdings in a prior TAM. The Associate Chief Counsel with jurisdiction over the TAM, however, may exercise the discretionary authority under § 7805(b) to limit the retroactive effect of any holding. This authority is exercised in rare and unusual circumstances.

.02 A TAM may be used to seek revocation or modification of an earlier TAM or revocation or modification of a private letter ruling (PLR). See Rev. Proc. 2025-1, section 11.04 et seq. with respect to revocation or modification of PLRs. Generally, a TAM that revokes or modifies a letter ruling or an earlier TAM will not be applied retroactively if: (1) the applicable law has not changed; (2) the taxpayer directly involved in the letter ruling or earlier TAM relied in good faith on it; and (3) revocation or modification would be detrimental to the taxpayer. The new TAM will be applied retroactively to the taxpayer whose tax liability was directly involved in the letter ruling or TAM if: (1) controlling facts have been misstated or omitted; or (2) the facts at the time of the transaction are materially different from the controlling facts on which the letter ruling or earlier TAM was based. If a letter ruling or a TAM is modified or revoked with retroactive effect, the notice to the taxpayer, except in fraud cases, should set forth the grounds on which the modification or revocation is being made and the reason why the modification or revocation is being applied retroactively.

.03 If an issue addressed in the TAM relates to a continuing action or a series of actions, it is generally applied until it is withdrawn or until the conclusion is modified or revoked by a final decision in favor of the taxpayer with respect to that issue, the enactment of legislation, the ratification of a tax treaty, a decision of the United States Supreme Court, or the issuance of temporary regulations, final regulations, a revenue ruling, or other statement published in the Internal Revenue Bulletin. Publication of a notice of proposed rulemaking does not affect the application of a TAM. If a new holding in a TAM is less favorable to the taxpayer than the holding in an earlier TAM, the new holding is generally not applied to the tax period when the taxpayer relied on the earlier holding. It will be applied to that tax period, however, if material facts on which the earlier TAM was based have changed.

.04 Under § 6110(k)(3), a taxpayer may not rely on a TAM issued by the Service for another taxpayer. In addition, retroactive or non-retroactive treatment to one member of a practice area directly involved in a letter ruling or TAM does not extend to another member of that same practice area, and retroactive or non-retroactive treatment to one client of a tax practitioner does not extend to another client of that same practitioner. The tax liability of each employee covered by a letter ruling or TAM relating to a pension plan of an employer is directly involved in the letter ruling or TAM.

.01 A taxpayer with respect to whom a TAM is issued, or for whom a TAM request is pending, may request that the appropriate Associate Chief Counsel limit the retroactive effect of any holding in the TAM or of any subsequent modification or revocation of the TAM. For a pending request for technical advice, the taxpayer should make the request for relief under § 7805(b) as part of the
