(a) Administrative proceeding. For purposes of section 7430, an administrative proceeding generally means any procedure or other action before the Internal Revenue Service that is commenced after November 10, 1988. However, an administrative proceeding does not include—

(1) Proceedings involving matters of general application, including hearings on regulations, comments on forms, or proceedings involving revenue rulings or revenue procedures;

(2) Proceedings involving requests for private letter rulings or similar determinations;

(3) Proceedings involving technical advice memoranda, except those submitted after the administrative proceeding date (as defined in paragraph (c) of this section); and

(4) Proceedings in connection with collection actions (as defined in paragraph (b) of this section), including proceedings under section 7432 or 7433, except proceedings brought under section 7433(e) and §301.7433-2 or proceedings otherwise described in §301.7430-8(c). See §301.7430-8.

(b) Collection action. A collection action generally includes any action taken by the Internal Revenue Service to collect a tax (or any interest, additional amount, addition to tax, or penalty, together with any costs in addition to the tax) or any action taken by a taxpayer in response to the Internal Revenue Service's act or failure to act in connection with the collection of a tax (including any interest, additional amount, addition to tax, or penalty, together with any costs in addition to the tax). A collection action for purposes of section 7430 and this section includes any action taken by the Internal Revenue Service under Chapter 64 of Subtitle F to collect a tax. Collection actions also include collection due process hearings under sections 6320 and 6330 (unless the underlying tax liability is properly at issue), and those actions taken by a taxpayer to remedy the Internal Revenue Service's failure to release a lien under section 6325 or to remedy any unauthorized collection action as described by section 7433, except those collection actions described by section 7433(e). An action or procedure directly relating to a claim for refund after payment of an assessed tax is not a collection action.

(c) Administrative proceeding date—(1) General rule. For purposes of section 7430 and the regulations thereunder, the term administrative proceeding date means the earlier of—

(i) The date of the receipt by the taxpayer of the notice of the decision of the Internal Revenue Service Office of Appeals;

(ii) The date of the notice of deficiency; or

(iii) The date on which the first letter of proposed deficiency that allows the taxpayer an opportunity for administrative review in the Internal Revenue Service Office of Appeals is sent.

(2) Notice of the decision of the Internal Revenue Service Office of Appeals. For purposes of section 7430 and the regulations thereunder, a notice of the decision of the Internal Revenue Service Office of Appeals is the final written document, mailed or delivered to the taxpayer, that is signed by an individual in the Office of Appeals who has been delegated the authority to settle the dispute on behalf of the Commissioner, and states or indicates that the notice is the final determination of the entire case. A notice of claim disallowance issued by the Office of Appeals is a notice of the decision of the Internal Revenue Service Office of Appeals. Solely for purposes of determining the administrative proceeding date, a notice of deficiency issued by the Office of Appeals is not a notice of the decision of the Internal Revenue Service Office of Appeals.

(3) Notice of deficiency. A notice of deficiency is a notice described in section 6212(a), including a notice rescinded pursuant to section 6212(d). For purposes of determining reasonable administrative costs under section 7430 and the regulations thereunder, the following will be treated as a notice of deficiency:

(i) A notice of final partnership administrative adjustment described in section 6223(a)(2).

(ii) A notice of determination of worker classification issued pursuant to section 7436.

(iii) A final notice of determination denying innocent spouse relief issued pursuant to section 6015.

(4) First letter of proposed deficiency that allows the taxpayer an opportunity for administrative review in the Office of Appeals. Generally, the first letter of proposed deficiency that allows the taxpayer an opportunity for administrative review in the Office of Appeals is the first letter issued to the taxpayer that describes the proposed adjustments and advises the taxpayer of the opportunity to contact the Office of Appeals. It also may be a claim disallowance or the first letter of determination that allows the taxpayer an opportunity for administrative review in the Office of Appeals.
