CAA Certification: What It Takes to Become a CAA (2026)

What Does CAA Certification Authorize in 2026?

CAA certification authorizes 3 specific actions a non-certified professional cannot perform. First, the CAA can inspect and certify original identity documents using IRS-approved forensic methods. Second, the CAA can sign a Certificate of Accuracy (Form W-7 (COA)) attesting that documents were verified. Third, the CAA can submit a Form W-7 packet to the IRS without including the original identity documents.

These authorities define the difference between a CAA and a regular Acceptance Agent. See the side-by-side comparison on the CAA vs Acceptance Agent page and the program structure on the IRS Acceptance Agent Program page.

How Does CAA Certification Renew?
