Internal Revenue Bulletin & Cumulative Bulletin Basics
"The Internal Revenue Bulletin (IRB) is the authoritative instrument for announcing official rulings and procedures of the IRS and for publishing Treasury Decisions, Executive Orders, Tax Conventions, legislation, court decisions, and other items of general interest." (IRS Website) "The last Bulletin for each month includes a cumulative index for the matters published during the preceding months. These monthly indexes are cumulated on a semiannual basis, and are published in the last Bulletin of each semiannual period.” (Introduction to IRBs)
Until 2008, "[t]he contents of this weekly Bulletin [were] consolidated semiannually into a permanent, indexed, Cumulative Bulletin." (IRS Website)
Types of documents that may be published in the IRB include:
- Actions on Decisions
- Congressional committee reports / Bluebooks
- Delegation orders
- Executive orders
- Proposed & final regulations/Treasury decisions
- Public laws
- Revenue rulings
- Revenue procedures
- Select court decisions
"Items published in the Internal Revenue Bulletin are . . . king of the IRS jungle and generally trump other IRS prouncements." (IRS Prouncements-Overview, 100-2nd, Bloomberg BNA)
IRBscontain numerical finding lists towards the back of each issue.
