(b) A Revenue Procedure is a statement of procedure that affects the rights or duties of taxpayers or other members of the public under the Code and related statutes or information that, although not necessarily affecting the rights and duties of the public, should be a matter of public knowledge.
(b) The Bulletin is published weekly. In order to provide a permanent reference source, the contents of the Bulletin are consolidated semiannually into an indexed Cumulative Bulletin. The Bulletin Index-Digest System provides a research and reference guide to matters appearing in the Cumulative Bulletins. These materials are sold by the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402.
(a) Issues answered by statute, treaty, or regulations;
(b) Issues answered by rulings, opinions, or court decisions previously published in the Bulletin;
(c) Issues that are of insufficient importance or interest to warrant publication;
(d) Determinations of fact rather than interpretations of law;
(e) Informers and informers' rewards; or
(f) Disclosure of secret formulas, processes, business practices, and similar information.
Procedures affecting taxpayers' rights or duties that relate to matters under the jurisdiction of the Service will be published in the Bulletin.
(b) It will be the practice of the Service to publish as much of the ruling or communication as is necessary for an understanding of the position stated. However, in order to prevent unwarranted invasions of personal privacy and to comply with statutory provisions, such as 18 U.S.C. 1905 and 26 U.S.C. 7213, dealing with disclosure of information obtained from members of the public, identifying details, including the names and addresses of persons involved, and information of a confidential nature are deleted from the ruling.
(c) Revenue Rulings, other than those relating to the qualification of pension, annuity, profit-sharing, stock bonus, and bond purchase plans, apply retroactively unless the Revenue Ruling includes a specific statement indicating, under the authority of section 7805(b) of the Internal Revenue Code of 1954, the extent to which it is to be applied without retroactive effect. Where Revenue Rulings revoke or modify rulings previously published in the Bulletin the authority of section 7805(b) of the Code ordinarily is invoked to provide that the new rulings will not be applied retroactively to the extent that the new rulings have adverse tax consequences to taxpayers. Section 7805(b) of the Code provides that the Secretary of the Treasury or his delegate may prescribe the extent to which any ruling is to be applied without retroactive effect. The exercise of this authority requires an affirmative action. For the effect of Revenue Rulings on determination letters and opinion letters issued with respect to the qualification of pension, annuity, profit-sharing, stock bonus, and bond purchase plans, see paragraph (o) of § 601.201.
(d) Revenue Rulings published in the Bulletin do not have the force and effect of Treasury Department Regulations (including Treasury decisions), but are published to provide precedents to be used in the disposition of other cases, and may be cited and relied upon for that purpose. No unpublished ruling or decision will be relied on, used, or cited, by any officer or employee of the Service as a precedent in the disposition of other cases.
(e) Taxpayers generally may rely upon Revenue Rulings published in the Bulletin in determining the tax treatment of their own transactions and need not request specific rulings applying the principles of a published Revenue Ruling to the facts of their particular cases. However, since each Revenue Ruling represents the conclusion of the Service as to the application of the law to the entire state of facts involved, taxpayers, Service personnel, and others concerned are cautioned against reaching the same conclusion in other cases unless the facts and circumstances are substantially the same. They should consider the effect of subsequent legislation, regulations, court decisions, and revenue rulings.
(f) Comments and suggestions from taxpayers or taxpayer groups on Revenue Rulings being prepared for publication in the Bulletin may be solicited, if justified by special circumstances. Conferences on Revenue Rulings being prepared for publication will not be granted except where the Service determines that such action is justified by special circumstances.
(b) In accordance with the standards set forth in subdivision (iv) of this subparagraph, each Assistant Commissioner is responsible for the preparation and appropriate referral for publication of Revenue Rulings reflecting interpretations of substantive tax law made by his office and communicated in writing to taxpayers or field offices. In this connection, the Chief Counsel is responsible for the referral to the appropriate Assistant Commissioner, for consideration for publication as Revenue Rulings, of interpretations of substantive tax law made by his Office.
(c) In accordance with the standards set forth in subdivision (iv) of this subparagraph, each Assistant Commissioner and the Chief Counsel is responsible for determining whether procedures established by any office under his jurisdiction should be published as Revenue Procedures and for the initiation, content, and appropriate referral for publication of such Revenue Procedures.
