Revenue Rulings are public administrative rulings by the Internal Revenue Service (IRS) that apply the law to particular factual situations or refer to issues not adequately addressed by the code, regulations, or case law. A revenue ruling can be relied upon as precedent by all taxpayers. Revenue rulings are published in the Internal Revenue Bulletin (IRB) which is available in CCH IntelliConnect, and RIA Checkpoint.

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.
