ITIN Application Denied: How to Read the IRS Rejection Letter and Refile Without Losing Another 3 Months

The IRS sends back ITIN applications more often than first-time applicants expect. The good news is that most rejections are procedural, not substantive: the applicant qualifies, the paperwork was just not formatted in a way the IRS could process.

Reading the rejection letter correctly and acting on the specific item it flags is the difference between a clean refile and a six-month loop of repeated rejections. This guide walks through what the rejection letter actually says, the patterns we see most often in inherited cases, and the cleanest path to refile.

What the rejection letter looks like

When the IRS rejects a Form W-7, they typically return the package to the address you provided on the form, with one or more of the following enclosed:

• A CP-567 notice explaining that the W-7 was rejected and listing one or more specific reason codes.
• A short cover letter from the IRS ITIN Operation in Austin, Texas, summarising the issue.
• The original supporting documents you submitted (passport copy, tax return, supporting evidence).
• An annotation on the W-7 form itself with a hand-stamped reason or a circled field.

Less commonly, the rejection arrives as a revenue agent's letter asking for additional information rather than rejecting outright — in those cases you have a window (usually 45 days) to respond rather than a hard reject.

Read the cover letter first. The CP-567 reason codes are usually one of these patterns:

• Passport copy not acceptable / certification not recognised.
• Form W-7 incomplete or contains conflicting information.
• Tax return (1040 / 1040-NR) not attached or insufficient to support the qualifying reason.
• Reason for applying does not match supporting documents.
• Signature missing or does not match.
• Name as transliterated does not match passport machine-readable zone (MRZ).
• Dependent does not qualify for the credit being claimed.

Each of these has a specific fix. Identifying which one applies is the first step.

The five most common rejection patterns and what to do

1. Passport certification not recognised

This is the single most common rejection we see in cases that come to us after being processed elsewhere. The IRS recognises three sources for certified passport copies:

• A Certified Acceptance Agent (CAA) in good standing, certifying via the documented CAA procedure (in-person or approved video).
• A US embassy or consulate abroad, certifying via consular procedure.
• The issuing authority of the passport itself (e.g., a Japanese passport certified by the Japanese passport agency).

Notarisation by a US notary, certification by a tax preparer who is not a CAA, "certified true copy" stamps from local government offices in the applicant's country, base legal offices for military families — none of these are recognised by the IRS for W-7 purposes, even though they may be perfectly valid certifications for other administrative purposes.

The fix: have a CAA verify the passport. Online verification works and produces a Certificate of Accuracy (COA) that travels with the refiled package. The applicant's original passport never has to be mailed.

2. Form W-7 incomplete or inconsistent

Common sub-cases:

• Box 6f or 6g left blank when the reason code requires them.
• Foreign address (Box 2) different from passport address without explanation.
• Name fields inconsistent between W-7, passport, and supporting documents — a common issue for non-Latin-script passports where transliteration varies.
• Date format mismatch — the IRS expects MM/DD/YYYY in US format; applicants who write DD/MM/YYYY can trigger automated rejections.

The fix: a fresh W-7 with every field cross-checked against the passport's machine-readable zone and the tax return. If transliteration is the issue, attach a brief explanation noting the MRZ form of the name as authoritative.

3. Tax return not attached or insufficient

Reason code (b) — non-resident alien filing a US tax return — requires the related 1040 or 1040-NR to be attached to the W-7 package unless a specific exception applies. Filing the W-7 alone under (b) is a near-automatic rejection.

Similarly, reason code (e) — spouse of US citizen — requires the related joint return (1040 with both names) to be attached.

The fix: package the W-7 and the return together. If the return is not yet ready, do not submit the W-7 yet — wait until both pieces can travel together. If the IRS rejected because the return was not attached, refile both as one package.

4. Reason code does not match supporting documents

Example: applicant ticks reason (b) but the attached tax return shows no US-source income or filing obligation. The IRS will reject because the qualifying reason and the evidence do not align.

The fix: re-evaluate the actual qualifying reason. For LLC owners, the reason should match the LLC's tax activity. For FIRPTA sellers, reason (h) with the FIRPTA exception is usually correct. For spouses, reason (e). We re-run the eligibility analysis before refiling to ensure the reason code is defensible.

5. Dependent does not qualify

After the TCJA (2018 onward), the rules narrowed for dependent ITINs:

• Dependents living outside the US, Canada, or Mexico generally do not qualify for the dependent-based ITIN unless they meet a specific exception (military families, certain treaty cases).
• Dependents claimed as qualifying children for the Child Tax Credit must have an SSN, not an ITIN.
• The Credit for Other Dependents ($500) does work with an ITIN, but the dependent must still be a US tax resident or otherwise qualify.

Common case: a US-citizen parent files a joint return claiming children who live abroad and applies for ITINs for the children alongside the spouse's ITIN application. If the children do not meet the residency criteria, only the spouse's ITIN will issue.

The fix: confirm the dependent's qualifying status before refiling. In many cases, the children's ITIN applications should be withdrawn and the return restructured to claim only the spouse.

Decoding "documentation not acceptable" — the umbrella code

If the rejection letter says only "documentation was not acceptable", it can mean any of the following without further detail:

• Photocopy of passport rather than CAA-certified copy.
• Passport pages cropped, blurry, or missing.
• Certification stamp present but illegible.
• Certification by an agent who is not in the IRS Acceptance Agent Program.
• The applicant's signature on the W-7 was added after the certification date (the IRS reads the certification as covering only the version signed at that date).

When the letter is vague, the safest assumption is to redo the entire identity verification chain with a CAA. A clean online CAA verification produces a single record that resolves all five sub-cases at once.

Refiling: the clean path

A correct refile, in order:

1. Read the rejection letter line by line. Identify the specific reason code(s). If unclear, call the IRS Acceptance Agent Program at 267-941-1000 with your case reference number.
2. Eligibility re-check. Confirm the original qualifying reason still applies, or determine whether a different reason code is more defensible.
3. Reissue or recheck the supporting documents. Passport, tax return, supporting evidence, marriage certificate (for spouse cases), LLC documents (for owner cases) — whatever was flagged.
4. Sign a fresh W-7. Date the new signature after the rejection. Do not reuse the original signed form if it has been annotated by IRS staff.
5. CAA online passport verification if certification was the issue. This typically replaces every certification method that was used the first time.
6. Package and mail the refile to the IRS ITIN Operation in Austin via tracked delivery. Include a brief cover letter referencing the rejection and the corrective action.
7. Track. Refile processing is in the same queue as new applications: 7–11 weeks typical, longer during January–April peak.

If the rejection involved the tax return as well, package the fresh return with the refiled W-7. If only the W-7 was rejected and the return is still in IRS suspense, the W-7 refile alone is enough — the return resumes processing automatically when the ITIN issues.

Cases that need extra steps

Some rejection scenarios go beyond a simple refile.

Multiple family members rejected together

If a US-citizen taxpayer's spouse and children were all rejected on the same return, we recommend going back to the eligibility analysis for each family member individually. The spouse usually still qualifies for ITIN under reason (e). The children may or may not, depending on residency and the post-TCJA dependent rules. We run the actual tax-savings math before reapplying for any child whose ITIN does not move the federal tax bill.

Military service families with overseas certifications

Active-duty service members and DoD contractors stationed abroad have sometimes used base legal offices, embassy notaries, or military legal advisors to certify documents for ITIN purposes. These certifications are well-intentioned but not recognised by the IRS ITIN Operation. Online CAA verification resolves this cleanly without requiring a trip to a US consulate — the video procedure works from any location with reliable internet.

Time pressure from a pending refund

If a refund is pending and the statute of limitations is approaching, the safest path is to:

1. Refile the W-7 with the corrective actions.
2. File any required extension or protective claim for the underlying refund if the deadline is near.
3. Track aggressively — a Priority package includes weekly status checks and direct response to any IRS correspondence.

The statute of limitations for refunds is generally three years from the original return's due date. For a 2023 return originally due 15 April 2024, the refund-claim deadline is 15 April 2027.

The IRS issued a partial rejection

In some cases the IRS issues ITINs to part of a multi-applicant package (e.g., the spouse) and rejects others (e.g., the children). This usually arrives as separate letters. The spouse's CP565 (ITIN issuance notice) confirms their number; the children's CP567 explains the rejection. Treat the two notices separately — the spouse's ITIN is final, and the children's refile (if appropriate) goes forward independently.

What to send with the refile

Beyond the corrected W-7 and any updated supporting documents, the refile package should include:

• A brief cover letter (one page) referencing the prior case number, the rejection date, the rejection reason(s), and the specific corrective action taken.
• The certified passport copy from the new CAA verification, with the Certificate of Accuracy (COA) attached.
• The original or freshly-prepared tax return if it was part of the rejection.
• The prior IRS correspondence (CP-567 or rejection letter) as a reference.

We do not include the original IRS correspondence unmodified — the IRS does not need its own letter back. A copy of the case reference is enough.
