§ 301.6110-2 Meaning of terms. ( a ) *Written determination.* A “written determination” is a ruling, a determination letter, or a technical advice memorandum, as such terms are defined in paragraphs (d), (e), and (f) of this section, respectively. Notwithstanding paragraphs (d) through (f) of this section, a written determination does not include for example, opinion letters (as defined in § 601.201(a)(4) of this chapter), information letters (as defined in § 601.201(a)(5) of this chapter), technical information responses, technical assistance memoranda, notices of deficiency, reports on claims for refund, Internal Revenue Service decisions to accept taxpayers' offers in compromise, earnings and profits determinations, or documents issued by the Internal Revenue Service in the course of tax administration that are not disclosed to the persons to whose tax returns or tax liability the documents relate.
( b ) *Reference written determination.* A “reference written determination” is any written determination that the Commissioner determines to have significant reference value. Any written determination that the Commissioner determines to be the basis for a published revenue ruling is a reference written determination until such revenue ruling is obsoleted, revoked, superseded or otherwise held to have no effect.
( c ) *General written determination.* A “general written determination” is any written determination that is not a reference written determination.
( d ) *Ruling.* A “ruling” is a written statement issued by the National Office to a taxpayer or to the taxpayer's authorized representative (as such term is defined in § 601.201(e)(7) of this chapter) on behalf of the taxpayer, that interprets and applies tax laws to a specific set of facts. A ruling generally recites the relevant facts, sets forth the applicable provisions of law, and shows the application of the law to the facts.
( e ) *Determination letter.* A “determination letter” is a written statement issued by a district director in response to a written inquiry by an individual or an organization that applies principles and precedents previously announced by the National Office to the particular facts involved.
( f ) *Technical advice memorandum.* A “technical advice memorandum” is a written statement issued by the National Office to, and adopted by, a district director in connection with the examination of a taxpayer's return or consideration of a taxpayer's claim for refund or credit. A technical advice memorandum generally recites the relevant facts, sets forth the applicable law, and states a legal conclusion.
( g ) *Background file document* — ( 1 ) *General rule.* A “background file document” is— ( i ) The request for a written determination.
( ii ) Any written material submitted in support of such request by the person by whom or on whose behalf the request for a written determination is made,
( iii ) Any written communication, or memorandum of a meeting, telephone communication, or other contact, between employees of the Internal Revenue Service or Office of its Chief Counsel and persons outside the Internal Revenue Service in connection with such request or written determination which is received prior to the issuance (as such term is defined in paragraph (h) of this section) of the written determination, but not including communications described in paragraph (g)(2) of this section, and
( iv ) Any subsequent communication between the National Office and a district director concerning the factual circumstances underlying the request for a technical advice memorandum, or concerning a request by the district director for reconsideration by the National Office of a proposed technical advice memorandum.
( 2 ) *Limitations.* Notwithstanding paragraph (g)(1) of this section, a “background file document” shall not include any— ( i ) Communication between the Department of Justice and the Internal Revenue Service or the Office of its Chief Counsel relating to any pending civil or criminal case or investigation,

( h ) *Issuance.* “Issuance” of a written determination occurs, with respect to rulings and determination letters, upon the mailing of the ruling or determination letter to the person to whom it pertains. Issuance of a technical advice memorandum occurs upon the adoption of the technical advice memorandum by the district director.
( i ) *Person to whom written determination pertains.* A “person to whom a written determination pertains” is the person by whom a ruling or determination letter is requested, but if requested by an authorized representative, the person on whose behalf the request is made. With respect to a technical advice memorandum, a “person to whom a written determination pertains” is the taxpayer whose return is being examined or whose claim for refund or credit is being considered.
