Whether you’re searching for “what is IRS Form W-7-COA” or “how to complete ITIN Certificate of Accuracy,” you’ve come to the right place.
What Is an ITIN and Why Do You Need One?
Before diving into Form W-7-COA, let’s clarify the basics. An ITIN is a nine-digit tax processing number issued by the IRS to individuals who must file U.S. federal tax returns but can’t get an SSN. This includes nonresident aliens, their spouses, and dependents involved in U.S. tax matters like wage reporting, claiming refunds, or treaty benefits.
Common scenarios requiring an ITIN:
- Filing a U.S. tax return as a nonresident alien.
- Being claimed as a dependent or spouse on someone else’s return.
- Opening a U.S. bank account or reporting foreign income.
ITINs expire after three years of inactivity, so renewals are often necessary. To apply or renew, you submit Form W-7 (Application for IRS Individual Taxpayer Identification Number), typically with a federal tax return (like Form 1040).
What Is IRS Form W-7-COA?
IRS Form W-7-COA (Certificate of Accuracy for IRS Individual Taxpayer Identification Number) is a supporting document attached to Form W-7. It’s exclusively used by authorized Certifying Acceptance Agents (CAAs)—IRS-approved professionals or organizations—to certify the authenticity of an applicant’s identity and foreign status documents.
The form acts as a “seal of approval,” verifying that the CAA has reviewed original or certified copies of required documents. This eliminates the need for applicants to mail originals to the IRS, reducing risk and processing time. The latest version, revised August 2025, emphasizes secure document handling amid rising fraud concerns.
Key fact: Form W-7-COA is not for direct IRS submissions by individuals. Only CAAs can complete it.
Who Needs to File IRS Form W-7-COA?
Form W-7-COA is required when a CAA submits a Form W-7 on behalf of:
- Primary applicants: Nonresident aliens applying for an ITIN.
- Secondary applicants: Spouses or dependents listed on a U.S. tax return.
- Renewal applicants: Those with expiring ITINs (middle digits 70-88, 90-92, or 94-99).
If you’re not using a CAA, skip Form W-7-COA and send originals directly to the IRS. CAAs are ideal for international applicants, as they handle verification via in-person or video interviews.
| Who Files | When Required | Benefits |
|---|---|---|
| Certifying Acceptance Agents (CAAs) | With every Form W-7 submission | Verifies docs; avoids mailing originals |
| Individuals | Never—only CAAs use it | N/A |
| Tax Professionals (non-CAAs) | Not applicable | Use direct IRS method instead |
Purpose of IRS Form W-7-COA: Ensuring Accuracy and Compliance
The primary purpose of IRS Form W-7-COA is to certify that the applicant’s supporting documents are genuine, complete, and accurately establish:
- Identity: Proves who the applicant is.
- Foreign status: Confirms non-U.S. citizenship or residency.
- Residency (if applicable): For certain exceptions.
By signing, the CAA attests under penalty of perjury that they’ve followed IRS guidelines in Publication 4520 (Acceptance Agents Guide for ITINs). This certification combats fraud, as the IRS scrutinizes ITIN apps due to past misuse.
Without it, CAA-submitted applications may be rejected, delaying ITIN issuance by weeks.
Required Documents for ITIN Applications with Form W-7-COA
CAAs must review originals or certified copies. A passport is the only standalone document proving both identity and foreign status. Otherwise, combine two or more from this IRS-approved list:
- Identity: National ID card, U.S. driver’s license, U.S. military ID, birth certificate, or visa.
- Foreign Status: Visa, foreign passport, or foreign driver’s license.
- For Dependents: Passport or civil birth certificate (CAA can authenticate these); originals/certified copies for others.
CAAs retain copies and attach them to the submission. For foreign military IDs, send originals directly to the IRS.
