Technical Advice Memoranda Basics
"A technical advice memorandum, or TAM, is guidance furnished by the Office of Chief Counsel upon the request of an IRS director or an area director, appeals, in response to technical or procedural questions that develop during a proceeding. A request for a TAM generally stems from an examination of a taxpayer's return, a consideration of a taxpayer's claim for a refund or credit, or any other matter involving a specific taxpayer under the jurisdiction of the territory manager or the area director, appeals." (IRS Website)
"Technical Advice Memorandums (TAM) are requested by IRS area offices after a return has been filed, often in conjunction with an ongoing examination. TAMs are binding on the Service in relation to the taxpayer who is the subject of the ruling." (Private Letter Rulings and Technical Advice Memorandums, IRM § 126.96.36.199.10)
TAMs are not published in the Internal Revenue Bulletin.
