Whether you’re interested in becoming a Certified Acceptance Agent (CAA) or looking to renew your application, we want to be certain you have all the necessary information to move forward. In this article, you’ll learn what a Certified Acceptance Agent is, how this certification can benefit your business, and the exact steps and requirements for applying, training, and maintaining your status. Follow our step-by-step guide to ensure you receive the right training and submit all the correct materials for a successful application process
What is an IRS Certified Acceptance Agent?
A Certified Acceptance Agent is a person (or business) authorized by the IRS to help individuals who don’t qualify for a Social Security number obtain an Individual Taxpayer Identification Number (ITIN), so they can file Form 1040 and other tax forms and schedules.
While both Acceptance Agents (AA) and Certified Acceptance Agents (CAA) assist taxpayers with ITIN applications, the key difference is that a CAA has additional authority to certify original identification documents for the IRS. This means clients don’t have to mail sensitive documents like passports to the IRS, which makes the process faster and more secure.
Choosing to become a CAA rather than a standard AA offers significant advantages. It enhances client trust, reduces processing delays, and allows you to provide a more convenient service, especially if your business serves a community with a high number of ITIN applicants. If your business is in a place with an influx of taxpayers with ITINs, you could benefit from having this certification.
Steps to become an IRS-Certified Acceptance Agent
Becoming a Certified Acceptance Agent requires completing specific requirements, including mandatory training, submitting an application, and uploading documentation.
There are four key steps to become an IRS-Certified Acceptance Agent, and you must complete each one thoroughly and accurately to ensure the IRS accepts your application.
Step 1: Complete ITIN Acceptance Agent training
You must complete the mandatory IRS training session designed for ITIN Acceptance Agents. This training covers essential topics such as the ITIN application process, eligibility requirements, proper completion of Form W-7, and how to assist taxpayers who do not qualify for a Social Security number. It also includes guidance on verifying identification documents and understanding your responsibilities as an agent to ensure compliance with IRS standards.
Step 2: Complete forensic document training
You must complete a forensic training course available on the IRS website. This training is separate from the general ITIN Acceptance Agent training and focuses on teaching you how to verify and authenticate identification documents submitted by taxpayers.
It covers techniques for detecting fraudulent documents, understanding security features on passports and government-issued IDs, and ensuring compliance with IRS standards for document review. Successfully completing this course is essential for Certified Acceptance Agents because it gives you the authority to certify original documents without requiring clients to mail them to the IRS.
Step 3: Submit your Certified Acceptance Agent application
Before you can complete the electronic IRS-Certified acceptance agent application, you must have an IRS e-Services account. Once you have access, log into your account and select Acceptance Agent Application from the menu.
The application typically requires you to provide business and contact information, identify responsible parties within your organization, and confirm that all listed individuals have completed the required training. You will also need to upload signed training certificates and jurats for each responsible party.
When completing the application, you’ll indicate whether you are applying as a Certified Acceptance Agent (CAA) or a standard Acceptance Agent (AA). CAAs have additional responsibilities and privileges, such as certifying original identification documents, which requires completing forensic document training and uploading proof of that training.
Step 4: Upload CAA documentation
All new Certified Acceptance Agent applicants and renewals must complete Form 13551, Application to Participate in the IRS Acceptance Agent Program through the IRS e-Services portal (mailed submissions are no longer accepted).
After submitting your application through e‑Services, you should wait approximately 24 hours before using the CAA Documentation Upload Tool. There, you’ll upload essential documents such as:
- Forensic training certificates (valid for four years)
- Proof of professional credentials (PTIN or EA license)
- Citizenship or non-profit status documentation, if applicable
The IRS automatically conducts background and tax compliance checks, so no fingerprint cards are needed.
Understanding the Certified Acceptance Agent application process
To obtain and maintain your status as a Certifying Acceptance Agent, it’s important to stay compliant with IRS requirements. Key components of the application process include:
- Complete at least five W-7 applications annually: CAAs must facilitate a minimum of five ITIN applications each year to remain active in the program.
- Undergo routine background and tax compliance checks: The IRS conducts check on both the business entity and all responsible parties to ensure compliance.
- Ensure your application and documentation are complete: Applications missing required fields, jurats, or certificates, including any forensic training for CAAs, will not be processed.
- Verify all responsible parties complete required training: Everyone listed on the application must finish both the ITIN acceptance agent training and forensic training (for CAAs).
Completing your training and certification for a Certified Acceptance Agent
In the past, tax preparers have had to submit Certified Acceptance Agent applications through the mail. But the IRS recently introduced a new online process, which has reduced application processing time for properly submitted documents from 120 days to 60 days.
Training requirements and resources for a Certified Acceptance Agent
Becoming an IRS-Certified Acceptance Agent requires specific training and adherence to rigorous standards. Individuals or entities wishing to obtain certification must complete mandatory ITIN Acceptance Agent training and demonstrate proficiency in helping foreign individuals obtain ITINs.
Additional forensic document training is required for Certified Acceptance Agents to authenticate identification documents. The IRS has a Certified Acceptance Agent FAQ page to address questions and concerns about applying for certification.
How long does it take to become a Certified Acceptance Agent?
Becoming a Certified Acceptance Agent (CAA) typically spans several stages, from completing training to receiving IRS approval, and generally takes about 60 to 75 days depending on the IRS workload.
- Training: Complete ITIN and forensic document training (1–2 weeks).
- Account Setup: Register for IRS e‑Services (about 1 week).
- Application Submission: Submit Form 13551 and upload required documentation (same day).
- IRS Review: Background and compliance checks, then approval (about 60 days).
Delays can occur if documentation is incomplete or during peak IRS processing periods.
Maintaining your certification and compliance
For applicants renewing their IRS-Certified Acceptance Agent status, it’s best to complete and submit Form 13551 at least six months before your certification expires. You will also need to attach your certificate to Form 13551. Certified Acceptance Agent certificates expire on December 31 the fourth year after the IRS approves your application or renewal.
