IRS Technical Advice Memorandum — Business Tax Guidance — Definition Glossary

Defined by Sarah Mitchell, CPA | Reviewed by: James Okafor, EA | Updated May 2026

Full Definition

An IRS Technical Advice Memorandum (TAM) is a written guidance document issued by the IRS National Office in response to a request from an IRS field agent (Revenue Officer or Examiner) who encounters an unusual or complex tax issue during examination or collection. TAMs interpret the tax law as it applies to a specific set of facts — they are legally binding on the IRS for the case at issue but do not have precedential value for other taxpayers. Businesses involved in TFRP disputes, OIC negotiations, or complex 941 payroll tax assessments may benefit from requesting a TAM through their assigned IRS employee if the case involves novel legal issues. TAMs are publicly released (with taxpayer identifying information redacted) after issuance and can serve as persuasive authority in similar cases, even though not formally binding.

Understanding IRS Technical Advice Memorandum — Business Tax Guidance is essential for any business owner navigating IRS enforcement or business tax debt.
