A rejected ITIN application does not just mean filling out a form again. It means restarting the IRS processing clock at zero, adding 7 to 11 weeks to your timeline, retrieving and resubmitting documents, and, in some cases, losing deductions or missing filing deadlines while you wait. Every rejection the IRS issues is accompanied by a specific reason code. Understanding what triggers each one is the most reliable way to make sure your application goes through on the first submission.
This guide covers the most common rejection causes in order of frequency, explains the IRS logic behind each one, and gives you concrete prevention steps for each.
How the IRS Reviews a W-7 Application
When a Form W-7 package arrives at IRS ITIN Operations in Austin, it goes through a sequential review. Processing staff check:
- That Form W-7 is the current version and is fully completed
- That the reason box selected matches the attached documentation
- That the applicant’s name, date of birth, and citizenship on Form W-7 match the identity documents
- That the identity documents are current, valid, and satisfy both identity and foreign status requirements
- That a complete U.S. tax return is attached — or that valid exception documentation is included
- That the tax return is signed and the ITIN applicant is listed
A failure at any one of these checkpoints produces a CP566 notice (more information needed) or a CP567 notice (rejection). Both restart the clock. If you receive a CP567, the entire application must be corrected and resubmitted from scratch — what to do after a rejection is covered in the recovery guide. This guide focuses on preventing that outcome entirely.
Rejection Reason 1: Name Mismatch Between Form W-7 and Identity Documents
Why it happens: The IRS compares Line 1a of Form W-7 — your legal name — character by character against your submitted identity document. Any difference, however minor, flags the application.
What the IRS is checking for: Identity fraud prevention. A name that doesn’t match the passport exactly signals either an error or a potentially fraudulent submission. The IRS does not make judgment calls on which differences are “close enough.”
What triggers rejection:
- A middle name on the passport that is omitted on Form W-7
- A hyphenated surname written without the hyphen
- Diacritical marks (accents, tildes, cedillas) present in one place and absent in the other
- A nickname or shortened version of a legal name (e.g., “Mike” instead of “Michael”)
- A name transliterated differently from a non-Latin script
How to prevent it: Copy your name from your passport onto Form W-7 exactly — character by character, including all middle names, hyphens, and diacritical marks. If your passport uses a Latin transliteration of a name from a non-Latin script, use that transliteration on Form W-7. If there is any legitimate discrepancy (e.g., a legal name change since the passport was issued), attach documentation explaining the difference — a marriage certificate or court order — alongside your application.
Rejection Reason 2: Expired Identity Document
Why it happens: The IRS requires every submitted document to be current — not expired — at the time of submission. This applies to passports, national identity cards, driver’s licenses, and every other document on the accepted list.
What the IRS is checking for: Document validity. An expired passport cannot reliably confirm identity because the photo and information may no longer represent the applicant, and the issuing country has effectively withdrawn its certification.
What triggers rejection:
- A passport with an expiry date that has passed, even by one day
- A national identity card past its expiry date
- A driver’s license that has lapsed
- Any document where the expiry date is not clearly legible
How to prevent it: Check every document’s expiry date before submitting. If your passport is expired or expiring within the next few months, renew it before applying — or use a current alternative document. The IRS will also accept documents without a standard expiry date (such as some civil birth certificates) if they were issued within the past 12 months. The complete breakdown of all 13 IRS-accepted document types includes the specific requirements for each one.
Rejection Reason 3: Notarized Copy Submitted Instead of Certified Copy
Why it happens: This is one of the most misunderstood requirements in the ITIN process. Many applicants assume that having a document notarized makes it acceptable — it does not.
What the IRS is checking for: Document authenticity. A certified copy is one that has been authenticated by the original issuing agency — the embassy, passport office, or government department that issued the original document — and bears its official stamp or seal. A notarized copy only confirms that a notary witnessed you signing or presenting the document. The notary is certifying your signature, not the document’s authenticity.
What triggers rejection:
- A photocopy of a passport bearing a notary stamp
- A bank letter or government document with a notary seal rather than the issuing agency’s seal
- Any document authenticated by a notary rather than the issuing authority
How to prevent it: Submit original documents, a certified copy from the issuing agency, or documents certified by an IRS-authorized Certifying Acceptance Agent (CAA). A CAA is specifically authorized by the IRS to certify identity documents on its behalf — which is what makes applying without mailing your original passport possible. Nolly, as a CAA, can certify your passport copy to IRS standards without you sending the original internationally.
Rejection Reason 4: Wrong Reason Box Checked on Form W-7
Why it happens: Form W-7 has eight reason boxes (a through h). The IRS uses the box you check to verify that the attached documentation supports the stated tax purpose. A mismatch between the box and the documentation triggers rejection.
What the IRS is checking for: Confirmed tax purpose. The ITIN program exists to allow non-U.S. residents to comply with U.S. tax law — the IRS requires evidence that the applicant has a legitimate, specific tax reason for needing the number.
What triggers rejection:
- Checking box b (nonresident alien filing a U.S. return) but attaching FIRPTA exception documents instead of a tax return
- Checking box a (treaty benefit) without also checking box h as required
- Checking an exception box without attaching the specific documentation that exception requires
- Leaving the reason box blank
How to prevent it: Match your reason box to your actual situation and your attached documentation. Box b is correct for most applicants filing Form 1040-NR. Box h is for exception claims — and must identify the specific exception by number and subcategory on the dotted line beside it. The Form W-7 line-by-line guide explains each box and the documentation each one requires. If you are claiming an IRS exception to the tax return requirement, the exceptions guide covers exactly what each exception requires in place of a return.
Rejection Reason 5: Missing, Unsigned, or Incomplete Tax Return
Why it happens: In most cases, a completed U.S. federal tax return must accompany Form W-7. The return establishes why the ITIN is needed and what income is being reported. Without it — or with an incomplete or unsigned version — the IRS has no basis for issuing the number.
What the IRS is checking for: A valid tax filing purpose. The IRS will not issue ITINs on speculation or in advance of a tax obligation being established.
What triggers rejection:
- The tax return is missing entirely
- The return is present but unsigned
- The return is incomplete — missing schedules, blank income lines, or absent attachments
- The return and Form W-7 are submitted in the wrong order (return should be behind the W-7, not in front)
- An incorrect return type is used (e.g., a resident Form 1040 when Form 1040-NR is required for a nonresident)
- The SSN/ITIN field on the return is filled in rather than left blank for the IRS to complete
How to prevent it: Prepare your Form 1040-NR completely and accurately before submitting. Sign it. Leave the SSN/ITIN field blank. Place Form W-7 on top of the return — not underneath. If you have dependents also applying, each person’s Form W-7 goes on top of the return as a bundle.
For non-U.S. residents who need help preparing Form 1040-NR correctly, Nolly’s U.S. tax return service handles this alongside the ITIN application.
Rejection Reason 6: Insufficient Documents to Prove Foreign Status
Why it happens: Every ITIN applicant must prove both identity and foreign status. A passport satisfies both on its own. Every other document proves only one — so applicants without a passport must submit two documents, and together they must collectively cover both requirements.
What the IRS is checking for: Confirmation that the applicant is not a U.S. citizen or lawful permanent resident. Without foreign status evidence, the IRS cannot issue an ITIN — because only non-SSN-eligible individuals qualify.
What triggers rejection:
- Two identity-only documents submitted (e.g., a U.S. driver’s license and a U.S. state ID) with no foreign status document
- A national identity card that is missing required fields — photo, name, current address, date of birth, and expiry date must all be present
- A document submitted as both identity and foreign status proof when it only qualifies for one
How to prevent it: If you are not using a passport, map your documents against the IRS’s two requirements before submitting. A national identity card that meets all field requirements satisfies both. A foreign driver’s license proves identity but not foreign status — it needs to be paired with a civil birth certificate or similar document that establishes foreign status. If you are unsure whether your specific document combination works, applying through a CAA gives you a pre-submission review.
Rejection Reason 7: Using an Outdated Version of Form W-7
Why it happens: The IRS periodically updates Form W-7 — the current revision is December 2024. Prior versions have different fields, different exception tables, and sometimes different instructions. Submitting an older version is an automatic rejection.
How to prevent it: Always download Form W-7 directly from irs.gov immediately before completing and submitting your application. Do not reuse a form you saved months ago. The form’s revision date appears in the bottom-left corner — confirm it reads “Rev. December 2024” or the most current revision available at the time you apply.
Rejection Reason 8: Applying When You Are Eligible for an SSN
Why it happens: The IRS will not issue an ITIN to someone who qualifies for a Social Security Number. If you have work authorization in the United States — including certain visa holders such as H-1B, L-1, F-1 with CPT or OPT — you are required to apply for an SSN instead.
What the IRS is checking for: That the applicant is genuinely ineligible for an SSN. Submitting a Form W-7 when you could obtain an SSN — or already have one — is an error the IRS flags.
How to prevent it: Confirm your SSN eligibility before applying. If the Social Security Administration has denied your SSN application, attach the denial letter to your Form W-7 as required. The overview of who needs an ITIN versus an SSN covers the eligibility distinction in full.
The Cost of Getting It Wrong
A rejected application means:
- 7 to 11 weeks added to your timeline from the date of resubmission
- Documents returned — you must gather them again and resubmit
- Missed deadlines — if you needed the ITIN for a specific transaction, filing, or withholding certificate, that window may have passed
- Lost deductions — for rental property owners, the IRS can deny all deductions if Form 1040-NR is not filed within 16 months of its original due date
- Delayed FIRPTA refunds — foreign sellers waiting on a withholding refund cannot receive it until a correctly filed return with a valid ITIN is processed
The consequences compound when the original deadline was time-sensitive. What happens if you don’t apply for an ITIN when you need one covers the downstream tax and financial effects in more detail.
Frequently Asked Questions
Can I correct and resubmit immediately after a rejection?
Yes. You can resubmit a corrected application as soon as you have addressed the specific rejection reason cited in your CP567 notice. The notice identifies the exact issue — read it carefully before resubmitting to make sure you have corrected the right thing and not just resubmitted the same application.
Will the IRS tell me specifically why my application was rejected?
Yes. The CP567 rejection notice includes a reason code and a brief explanation. Common codes relate to documentation issues, name mismatches, and missing tax returns. The notice also tells you where to send your corrected application.
Does a rejected application affect my future applications?
No. A rejection does not create a record that harms future applications. You simply correct the error and resubmit. However, each resubmission goes through the full processing queue again, which is why avoiding rejection on the first attempt matters so much when timing is important.
If my application is rejected during tax season, how long does resubmission take?
The same 9–11 week peak-season timeline applies to resubmissions. There is no priority queue for corrected applications. This is why a rejection during a time-sensitive situation — a property closing, a filing deadline — can be particularly damaging.
