Certifying Acceptance Agent vs. Acceptance Agent: What ITIN Applicants Should Know

Understand the difference between an IRS-authorized Acceptance Agent and Certifying Acceptance Agent for Form W-7 and ITIN applications.

Human tax review approvedReviewed for accuracy · Updated July 15, 2026

Acceptance Agents and Certifying Acceptance Agents can both assist with Form W-7. The important difference is how supporting identity and foreign-status documents may be handled under current IRS rules.

Both roles assist with ITIN applications

An Individual Taxpayer Identification Number is issued by the IRS to certain people who need a U.S. taxpayer identification number but are not eligible for a Social Security number. Form W-7 is used to apply. Both types of IRS-authorized acceptance agents can help review eligibility, complete Form W-7, conduct the required applicant interview, and assemble an application.

What an Acceptance Agent does

An Acceptance Agent can help complete and submit Form W-7. Under current IRS instructions, an Acceptance Agent generally must submit original identification documents or copies certified by the issuing agency to the IRS for applicants. The agent helps organize the package but does not independently certify those documents to the IRS in the way a Certifying Acceptance Agent can.

What a Certifying Acceptance Agent does

A Certifying Acceptance Agent, often called a CAA, has additional IRS authorization and document-review responsibilities. A CAA can authenticate most qualifying original identity documents for primary and secondary applicants and complete Form W-7 (COA), Certificate of Accuracy.

Important limits apply. Foreign military identification cards cannot be authenticated by a CAA. For dependents, a CAA can authenticate only passports and civil birth certificates; other dependent documents may still need to be sent to the IRS as originals or issuing-agency-certified copies.

The CAA must have the original document or an issuing-agency-certified copy in its possession for the required review. The applicant interview may be conducted in person or by video under IRS procedures, but a video image alone is not a substitute for the required possession and examination of the document.

Does using a CAA mean an original passport never has to be mailed?

No one should promise that original documents are never required. A CAA can reduce the need to mail many original qualifying documents because the CAA may authenticate them and return them after review. Applicant type, document type, dependency status, and unusual facts can change what must be submitted.

The accurate statement is narrower: working with a CAA may allow many applicants to avoid mailing certain original identity documents to the IRS, subject to current IRS rules and the applicant’s circumstances.

Can a CAA approve or issue an ITIN?

No. A CAA does not approve or issue an ITIN and cannot guarantee that an application will be accepted. The IRS reviews the application and makes every final ITIN decision. CAA status is an authorization to assist and certify within defined limits; it is not IRS endorsement of the business and does not make the agent a government office.

What should an applicant expect?

  1. Confirm that the applicant needs an ITIN and is not eligible for an SSN.
  2. Identify the federal tax return or permitted exception connected to Form W-7.
  3. Review Form W-7 for completeness and consistency.
  4. Provide document instructions based on applicant and document type.
  5. Conduct the required interview and document review.
  6. Submit the complete package to the IRS and communicate what happens next.

An international applicant should also confirm how original documents will be delivered for the CAA’s physical review, how they will be returned, and what secure communication channel will be used. Sensitive documents should never be uploaded to an ordinary public inquiry form or sent through unapproved messaging.

How long does the process take?

IRS processing estimates can change by season, overseas filing, and application completeness. The current Form W-7 instructions provide estimates, but those estimates are not guarantees. Applicants should check current IRS guidance at the time of filing and allow additional time for document delivery, correction requests, or unusual facts.
