The Internal Revenue Bulletin is a weekly publication of the Internal Revenue Service. It is divided into four parts: (1) the 1986 Internal Revenue Code; (2) Treaties and Tax Legislation; (3) Administrative, Procedural and Miscellaneous and (4) Items of General Interest.
The Bulletin is the "authoratative instrument" of the Commissioner of Internal Revenue. As one can see from the four sections delineated above that official rulings, court decisions, Executive Orders, legislation and other general interest items are announced through the Bulletin.
