IRS Form 8821 — Tax Information Authorization — Definition Glossary

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

Full Definition

IRS Form 8821 is the Tax Information Authorization, allowing a designated representative (CPA, attorney, enrolled agent, lender) to receive confidential tax information from the IRS on the taxpayer’s behalf — without giving the representative authority to act or make decisions. Form 8821 is narrower than Form 2848 (Power of Attorney): a Form 8821 designee can receive transcripts, view account information, and discuss the account with the IRS, but cannot negotiate, sign documents, or represent the taxpayer in proceedings. For tax debt financing purposes, a lender or marketplace (like Tax Funds) may request a Form 8821 to access the business’s IRS account transcripts and verify the exact amount of tax debt before finalizing financing terms. Signing Form 8821 does not authorize anyone to make decisions about the tax debt — only to receive information. Form 8821 authorizations expire after a specified period unless the taxpayer revokes them earlier.

Understanding IRS Form 8821 — Tax Information Authorization is essential for any business owner navigating IRS enforcement or business tax debt.
