IRS Publication 5533-B – IRS Forms, Instructions, Pubs 2026

IRS Publication 5533-B – IRS Forms, Instructions, Pubs 2026 – Tax professionals looking to streamline client authorizations no longer need to rely solely on faxing, mailing, or uploading Forms 2848 (Power of Attorney) or 8821 (Tax Information Authorization). IRS Publication 5533-B (Rev. 6-2024) provides a clear, step-by-step roadmap for using the IRS Tax Pro Account to submit, view, and withdraw authorizations in real time.

This official IRS publication—titled Tax professionals: How to manage authorizations using Tax Pro Account—helps qualified tax pros save time, reduce paperwork, and deliver faster service to clients. Whether you’re submitting a new Power of Attorney (POA), Tax Information Authorization (TIA), linking your Centralized Authorization File (CAF) number, or withdrawing an active authorization, Publication 5533-B makes the process straightforward and digital.

What Is IRS Publication 5533-B and Why It Matters?

Published in June 2024 and available as a free PDF download from the IRS website, Publication 5533-B is a concise, practitioner-focused guide. It explains exactly how to manage authorizations through the secure Tax Pro Account portal at IRS.gov/taxproaccount.

Key highlights from the publication:

  • Real-time processing: Once a taxpayer approves (or you withdraw) an authorization, it updates the CAF database immediately.
  • One-time CAF linking: Connect your CAF number to view all active authorizations at a glance.
  • Simplified submission: Enter client and professional details that exactly match IRS records—no forms required for individual taxpayers.

This tool is part of the IRS’s ongoing digital transformation, complementing Publication 5533-A (for submission workflows) and helping reduce processing delays that used to take weeks or months.

Who Can Use the Tax Pro Account for Authorizations?

  • TIA requests: Any tax professional with a valid CAF number.
  • POA requests: Attorneys, CPAs, enrolled agents, enrolled actuaries, or enrolled retirement plan agents authorized to practice before the IRS.
  • Taxpayer requirements: Must have a U.S. or D.C. address that exactly matches IRS records and the ability to access (or create) an IRS Online Account for approval.

Important: The tool currently supports individual taxpayers only. Business authorizations still use traditional Form 2848/8821 processes in most cases (with recent business-firm expansions noted in 2026 IRS updates).

Step-by-Step: How to Manage Authorizations Using Tax Pro Account?

1. Access Your Tax Pro Account

Sign in at IRS.gov/taxproaccount using ID.me credentials (or create a new account if needed). The portal offers secure, one-stop access to authorizations, taxpayer information (within scope), and more.

2. Link Your CAF Number (One-Time Process – Highly Recommended)

Linking your CAF number lets you view your full inventory of active POAs/TIAs and withdraw them instantly.

  1. From your profile, select Link a CAF number.
  2. Follow the 2-step PIN request process.
  3. A PIN will be mailed to the address on file with the CAF (allow 1–2 weeks).
  4. Enter the PIN to complete linking.

Once linked, you can see all authorizations regardless of how they were originally submitted.

3. Submit a New POA or TIA Request

  1. Enter your (the professional’s) details: name, address, and CAF number.
  2. Enter the taxpayer’s details: name, address, and TIN—must match IRS records exactly.
  3. Select the tax matter(s) and period(s).
  4. For POA: Provide your electronic signature by checking the box and submit for validation.
  5. Optional but recommended: Notify the taxpayer to log into their IRS Online Account and approve the request (they simply check a box to sign electronically).

Taxpayers have up to 120 days to approve pending requests in their Online Account.

4. View or Withdraw Active Authorizations

  1. Go to the Taxpayers tab and select a client.
  2. Click Authorizations to see all active POAs/TIAs.
  3. View full details or click Withdraw for immediate real-time removal from the CAF.

This feature eliminates the need for FOIA requests or paper withdrawals—changes process in real time.

Key Considerations and Best Practices from Publication 5533-B

  • Exact match rule: Names and addresses must match IRS records precisely. Mismatches cause rejection.
  • U.S./D.C. address required: No foreign addresses for this digital process.
  • Real-time CAF updates: Approved requests or withdrawals update instantly—no waiting period.
  • Security: All actions use secure ID.me login and electronic signatures.
  • Address changes: Update your own address via Form 2848/8821 or written notification—not directly in Tax Pro Account.

Pro Tip: Always confirm the taxpayer’s current name/address via their recent IRS notice or Online Account before submitting.

Benefits of Managing Authorizations Digitally

  • Speed: Real-time processing vs. weeks for paper/fax.
  • Visibility: Full view of your authorization inventory once CAF is linked.
  • Client convenience: Taxpayers approve with a simple checkbox—no printing, signing, or mailing.
  • Reduced errors: Built-in validation catches mismatches early.
  • Scalability: Perfect for solo practitioners and firms handling dozens or hundreds of clients.

Recent IRS expansions (as of early 2026) have added business-firm capabilities for designated representatives, including employee access management and firm-level CAF linking—further enhancing efficiency for larger practices.
