Certified Acceptance Agents (CAAs) assist individuals in obtaining an Individual Taxpayer Identification Number from the IRS. They verify documents, authenticate identities, and ensure forms meet IRS requirements before submission. Their role reduces application errors and protects applicants from delays or rejections. By maintaining strict standards, CAAs build trust with clients and the IRS.

Compliance is crucial because CAAs face penalties for violating IRS guidelines. These penalties include warning letters, probationary status, or termination from the program entirely. Non-compliance also risks harming clients who depend on the prompt approval of taxpayer identification numbers. Each violation damages professional credibility and jeopardizes the CAA’s authorization.

Proper risk management safeguards both professionals and applicants in the ITIN process. Tax professionals must monitor error rates, maintain accurate records, and update procedures regularly. Applicants benefit when CAAs minimize compliance risks through strong internal systems. Effective compliance ensures smoother processing, client satisfaction, and continued program authorization.

What is a Certified Acceptance Agent

Certified Acceptance Agents (CAAs) are critical in the IRS program for issuing the Individual Taxpayer Identification Number. Their responsibilities extend beyond application assistance, as they must comply with strict regulations, implement risk management, and maintain accuracy throughout the process. Understanding their role is essential for applicants and organizations in this capacity. The following sections explain their definition, responsibilities, and differences from Acceptance Agents.

IRS Publication 4520 definition and ITANP connection

  • IRS Definition: A CAA is authorized pursuant to IRS Publication 4520 to assist foreign individuals in applying for an Individual Taxpayer Identification Number.

  • Program Connection: The program allows CAAs to serve as trusted intermediaries between the IRS and applicants who submit documentation.

  • Compliance Role: CAAs must comply with federal regulations, maintain adherence to IRS procedures, and ensure the accuracy of completed forms.

  • Risk Management: Their role reduces compliance risks for CAAs by improving the data collection and document verification processes.

Primary Responsibilities in the ITIN Application Process

  • Document Authentication: CAAs verify identity and status documents for applicants and dependents, ensuring compliance with all IRS requirements.

Documentation errors, poor data collection, and weak risk management controls create serious compliance risks for CAAs. By implementing accurate procedures, maintaining required records, and cooperating with the IRS, CAAs can reduce violations and ensure program adherence.

IRS Sanctions and Enforcement Actions

The IRS enforces a structured sanctions system to address compliance risks for CAAs and ensure program adherence. This system uses escalating levels of enforcement to reduce violations, enforce accuracy, and protect applicants for taxpayer identification numbers. The following sections explain the sanction framework, violations, and procedures for probation, reinstatement, and termination.

Overview of the IRS Four-Level Sanction System

  • Level One: Acceptance Letter: CAAs receive compliance confirmation when they adhere to all regulations and requirements.

  • Level Two: Warning Letter: The IRS issues letters for minor violations that do not prevent applicants from receiving service.

  • Level Three: Probation Letter: Serious violations subject CAAs to probationary status, requiring corrective action and improved compliance procedures.

  • Level Four: Termination Letter: Flagrant violations result in termination of the CAA program agreement and loss of authorization.

Examples of Minor, Serious, and Flagrant Violations

  • Minor Violations: Missing copies of IRS notices, incomplete procedures, or failing to notify applicants of temporary identification numbers.

  • Serious Violations: Inconsistent Certificate of Accuracy documents, invalid signatures, or repeated incomplete Form W-7 submissions.

  • Flagrant Violations: Submitting unauthorized documents, failing to maintain records, refusing to comply with IRS requests, or seasonal operations.

  • Compliance Risks for CAAs: Each violation type increases compliance risks and can result in penalties or program removal.

Process for Probation, Reinstatement, and Termination

  1. Probation Status: CAAs are placed on probation and converted to Acceptance Agents for at least one year.

  2. Corrective Action: CAAs must implement training, address violations, and reduce error rates by at least 50 percent.

  3. Reinstatement Review: The IRS conducts compliance reviews to determine if the CAA qualifies for reinstatement.

  4. Final Termination: If compliance is not achieved, the IRS enforces termination and prohibits further participation in the program.

The IRS sanctions system provides structured enforcement to address compliance risks for CAAs. By adhering to regulations and implementing effective risk management, CAAs can avoid penalties and successfully serve applicants.

Avoiding Common Compliance Mistakes

FAQs About CAA Compliance Risks

What happens if a CAA’s error rate exceeds 10%?

If a Certified Acceptance Agent has an error rate above 10%, the IRS may conduct a compliance review to evaluate procedures. High error rates create compliance risks for CAAs and can lead to probation, suspension, or termination. During probation, the CAA may be downgraded to Acceptance Agent status and required to reduce errors by at least 50%. Continued violations may result in permanent removal from the program, loss of authorization, and additional penalties.

How long must CAAs keep client records?

CAAs must maintain complete client records for three calendar years following the submission of Form W-7 applications. These records include Certificates of Accuracy, identification documents, intake sheets, training certifications, and IRS notices. The files may be stored electronically or in a tangible copy, but they must be secure and accessible for review. Maintaining these records is required to comply with IRS regulations and helps demonstrate adherence during audits or compliance reviews conducted by the IRS.

Can CAAs authenticate foreign military IDs?

No, under IRS regulations, Certified Acceptance Agents cannot authenticate foreign military identification cards. These documents must be submitted directly to the IRS for review. CAAs are limited to authenticating approved documents such as passports, birth certificates for dependents, and certain other identity records. Accepting or authenticating unauthorized documents is a compliance violation and may trigger penalties, probation, or program termination. Adhering strictly to document authentication rules protects applicants and reduces compliance risks for CAAs during ITIN submissions.

What documents can dependents use for proof of U.S. residency?

Dependents can use specific documents to prove U.S. residency depending on their age. For children under six, acceptable documents include U.S. medical records, school records, or state identification cards. School records, state IDs, or driver’s licenses are valid for dependents ages six to seventeen. For adults, documents such as U.S. bank statements, rental agreements, or utility bills are accepted. Each document must be current and valid to meet IRS requirements and ensure compliance with ITIN application procedures.

How often does the IRS conduct compliance reviews?

The IRS conducts compliance reviews periodically, with frequency depending on identified risk factors and error rates. Reviews may occur annually or less frequently if CAAs maintain low error rates and comply with regulations. However, CAAs with higher error rates, repeated violations, or flagged activities are prioritized for review. The reviews may be conducted in person or through correspondence, and CAAs are required to cooperate fully. Failure to comply can result in sanctions, probation, or termination.

What’s the difference between CP566 (suspense) and CP567 (rejection)?

A CP566 suspense notice means the IRS requires additional documents or data collection before completing an ITIN application. The application remains pending; approval may follow if the requested information is timely. A CP567 rejection notice, however, means the application was denied due to compliance violations or missing requirements. Applicants must correct all errors, prepare a new Form W-7, and resubmit it. Understanding these differences helps CAAs implement effective risk management and maintain compliance.
