On August 27, 2026, the Internal Revenue Service (IRS) released Tax Tip 2026-66 detailing the procedures and legal framework governing third-party authorizations for federal tax matters. This guidance clarifies how taxpayers can formally designate a representative—such as a certified public accountant, attorney, enrolled agent, or trusted family member—to interact with the IRS on their behalf. The authorization process is governed by Internal Revenue Code Section 6103(c) and implemented through Form 2848 (Power of Attorney and Declaration of Representative) and Form 8821 (Tax Information Authorization). The update emphasizes the distinctions between full representation rights and limited information access, the revocation procedures, and the specific scopes of authority granted under each form. With the IRS expanding digital submission options via the Tax Pro Account and Practitioner Priority Service, the guidance also addresses electronic signature requirements and processing timelines for the 2026 filing season.
Key Takeaways
- Two-Tier Authorization Structure: Taxpayers must choose between Form 2848, which grants full representation rights including the ability to execute waivers, sign returns, and receive refunds, and Form 8821, which only permits the designee to inspect and receive confidential tax information without representation authority. Selecting the incorrect form can delay case resolution and limit the representative’s ability to negotiate with IRS Appeals or Collection.
- Digital Submission and CAF Integration: The IRS now strongly encourages electronic filing of authorization forms through the Centralized Authorization File (CAF) system via the Tax Pro Account portal. Paper submissions face processing delays of 4–6 weeks, whereas digital submissions typically update within 2–3 business days. Practitioners must ensure their CAF numbers are active and linked to their PTINs to avoid rejection.
- Revocation and Duration Controls: Authorizations remain valid until revoked by the taxpayer, the representative withdraws, or a specific expiration date is reached. Taxpayers can revoke authority by filing a new Form 2848/8821 with the “Revoke” box checked or by submitting a written statement. The IRS stresses that oral revocations are insufficient; written documentation is mandatory to protect taxpayer privacy under IRC §6103.
