An Individual Taxpayer Identification Number (ITIN) application can be rejected for five main reasons: an incomplete or incorrect Form W-7, missing or invalid supporting documents, expired documents, no valid reason for needing an ITIN, or eligibility for a Social Security Number (SSN). Understanding these common mistakes is the first step to ensuring your application is approved. This guide explains why an ITIN application is rejected, highlights the benefits of avoiding denial, describes its main uses, and outlines the key components of a successful submission.
Why ITIN Applications Fail and How to Succeed#
An ITIN application rejection stalls your ability to file U.S. taxes, open a bank account, or build credit. The Internal Revenue Service (IRS) has strict guidelines for the Form W-7, the Application for IRS Individual Taxpayer Identification Number. A small error can cause the IRS to reject your application.
Simple mistakes often cause rejection. Forgetting to sign the form is a common error. Another frequent mistake is entering a name that does not exactly match the name on your passport. Do not use nicknames or abbreviations.
The biggest challenge is providing the correct documentation. Most ITIN application failures happen at this stage.
Common Documentation Pitfalls#
Submitting the wrong type of documents is the number one reason for ITIN application denial. The IRS requires you to mail your original documents or certified copies obtained from the issuing agency.
Here are three common document mistakes:
- Sending photocopies. The IRS rejects photocopies immediately.
- Submitting a national identity card that lacks required information, including your name, photo, address, date of birth, and expiration date.
- Forgetting to include a required U.S. visa if you are using a foreign passport as your only identification document.
An ITIN application is a formal request. The IRS treats it with the same scrutiny as a tax return. A rejection often signals the information was not sufficient to prove identity or a legitimate tax need as defined by U.S. tax law.
The Five Core Reasons for Rejection#
Nearly every ITIN rejection falls into one of these five categories. Knowing them helps you prepare a strong application. The following table breaks down each issue and explains how to fix it.
| Rejection Reason | What It Means | How to Fix It |
|---|---|---|
| Incomplete or Incorrect Form W-7 | You left fields blank, your name does not match your passport, or you forgot to sign and date the form. | Review every line on your Form W-7. Check that it matches your supporting documents perfectly, then sign and date it. |
| Missing or Invalid Supporting Documents | You did not mail an original or certified copy of an approved document, like your passport, to prove your identity and foreign status. | Provide one of the 13 acceptable documents in its original form or as a certified copy from the issuing agency. Do not send photocopies. |
| Expired Documents | The identification you sent, most often a passport, was expired when the IRS received your application. | Make sure your passport and any other ID are current. Renew them before you apply for the ITIN, if they are close to expiring. |
| No Valid Reason for Needing an ITIN | You did not attach a U.S. federal tax return or prove you qualify for one of the exceptions. | Attach a completed federal tax return to your Form W-7. Include all required proof, if you qualify for an exception. |
| You Are Eligible for a Social Security Number (SSN) | The IRS believes you can get an SSN, which makes you ineligible for an ITIN. | Get a denial letter from the Social Security Administration (SSA) and include it with your ITIN application, if you are not eligible for an SSN. |
Getting these five areas right increases your chances of a successful application.
What is Behind Most ITIN Rejections? Paperwork Errors.#
Most ITIN application rejections happen because of simple paperwork mistakes. The Form W-7 is the foundation of your application. The entire application fails, if it is not perfect.
A small mistake can cause an instant rejection from the Internal Revenue Service (IRS). This includes a missing signature, an incorrect address, or a name that does not exactly match your passport. These are hard requirements.
Choosing the wrong reason for needing an ITIN is another common mistake. You must list the specific treaty country and the exact article number that applies to you, if you check the box to claim tax treaty benefits. Without this detail, the IRS will return the incomplete application. These details prove you have a legitimate need for a Tax Identification Number (TIN).
Supporting Document Mistakes Are Frequent#
Getting the Form W-7 right is only half the task. Your supporting documents are equally critical. Many applications fail at this stage. Most rejections are due to documentation and form errors, not applicant ineligibility.
Common errors include sending an expired passport, forgetting a required visa, or providing documents with conflicting personal details. You must submit your original documents or certified copies from the issuing agency. Regular photocopies guarantee rejection. You can learn more about these common ITIN processing problems and their solutions.
To avoid problems, check every document against the strict IRS guidelines. Use this quick checklist for a foreign passport:
* Is it expired? An expired passport leads to an automatic rejection. The IRS will not review the rest of your application.
* Is it an original or a certified copy? Photocopies are not accepted.
* Does the name match the W-7 exactly? Any difference will be flagged.
By carefully preparing your Form W-7 and supporting documents, you address the top reasons for ITIN rejections and improve your application's chance of success.
The Cost of an ITIN Rejection Goes Beyond Paperwork#
An ITIN application rejection is not a small administrative issue. It is a major roadblock that causes serious delays and financial opportunity costs.
The IRS takes 7 to 11 weeks to process a standard ITIN application. A rejection means that entire clock starts over. You must find the mistake, fix it, and resubmit, pushing your total wait time to several months.
This is not just an inconvenience. For many non-U.S. residents, a stalled ITIN means you cannot file a U.S. tax return, claim a tax refund, or open a U.S. bank account. It can stop your plans to sell on an e-commerce platform or meet your U.S. tax obligations on time.
The Financial and Logistical Impact#
A rejection creates other tangible problems. You must mail your original passport to the IRS when you apply on your own. A rejection forces you to risk it getting lost or damaged again.
You are financially paralyzed during this loop. You cannot open a brokerage account, apply for U.S. credit, or rent an apartment in some cases without a valid tax ID number. Every week of delay puts your financial life in the U.S. on hold.
A rejected ITIN application creates a significant opportunity cost. It can delay access to U.S. banking, freeze business operations, and hold up thousands of dollars in tax refunds. A simple paperwork mistake turns into a substantial financial problem.
This is a common problem for people who apply alone. The IRS's own data is revealing. Between 2022 and 2024, the agency rejected over half a million applications. The rejection rate for self-filers was 22% in 2023. Applications filed through a Certified Acceptance Agent (CAA) had a much lower 12.27% rejection rate. This shows how much small technical details matter. You can find the full research on these ITIN application trends from the Taxpayer Advocate Service.
What to Do When Your ITIN Application Is Rejected#
A rejection notice from the IRS for your ITIN application is frustrating, but it is a fixable problem. The recovery process starts when you get the official letter, usually the CP567 notice.
Analyze the Rejection Notice#
Your first action is to read the IRS notice carefully. This letter explains the exact reason your Form W-7 application was denied. Understanding that reason is key to fixing the issue.
Correct the Specific Error#
You can take action once you have identified the problem. Most rejections are due to common, correctable mistakes:
* Completing a new Form W-7: Ensure every field is filled out correctly. The information must perfectly match your supporting documents.
* Obtaining proper documentation: Secure an original or certified copy of your passport, national ID card, or another required identification.
* Providing missing information: Check if you forgot to attach your U.S. tax return or evidence for an exception. Ensure everything required is in the package.

A rejection restarts the clock. It often comes with extra fees and can set you back by as much as six months.
Resubmit Your Corrected Application#
You need to resubmit the entire application package after you have fixed the error the IRS identified. Send the whole application again, not just the corrected document.

How a Certified Acceptance Agent Minimizes Rejection Risk#
Working with an IRS Certified Acceptance Agent (CAA) is the most effective way to avoid an ITIN application rejection. A CAA is an individual or firm authorized by the IRS to help applicants with the W-7 process.
Their main advantage is the ability to verify your identity and certify your supporting documents. This means you do not have to mail your original passport or other vital ID to the IRS. This eliminates the risk of it getting lost or damaged. A CAA is your first defense against common ITIN mistakes.
Expert Review and Pre-Submission Checks#
A CAA provides an expert review of your Form W-7 before it is sent to the IRS. They are trained to spot errors that trigger rejections, such as incorrect information, a missing signature, or the wrong reason for needing an ITIN. This review is designed to fix the issues that cause most applications to fail.
This proactive step is important. The National Taxpayer Advocate noted that applicants who apply alone are over twice as likely to have their application rejected or suspended. When the IRS sends a rejection notice, the explanation is often vague. This forces you to guess what went wrong and restart the months-long process.
The Value of Professional Guidance#
A CAA streamlines the entire process. They ensure your application is complete, accurate, and compliant with current U.S. tax laws. The result is a much higher chance of approval on the first try, saving you from the stress and delays of a rejection.
By certifying your documents and preparing your Form W-7, a CAA transforms a high-risk process into a clear one. Their involvement provides peace of mind and is the surest path to securing your Tax Identification Number (TIN) without setbacks.

Common Questions After an ITIN Rejection#
An ITIN application rejection from the IRS raises many questions. Here are answers to some of the most common ones.
Why Do I Need an ITIN?#
You need an Individual Taxpayer Identification Number (ITIN) if you have a U.S. tax filing obligation but do not qualify for a Social Security Number (SSN). The IRS uses it to track tax returns and payments for foreign nationals and other non-residents.
People get an ITIN for several practical reasons:
Filing a U.S. federal tax return as a nonresident alien.
Being claimed as a spouse or dependent on another person's tax return.
Claiming tax treaty benefits to lower taxes withheld from U.S. income.
Opening a U.S. bank account or applying for a credit card.
* Running a business on U.S. platforms like Amazon or Etsy.
The ITIN is used whenever a financial or tax process in the U.S. requires an SSN that you do not have.
How Long Should I Wait to Reapply After a Rejection?#
There is no mandatory waiting period. You can and should reapply as soon as you have fixed the issue that caused the ITIN application rejection.
First, carefully read the IRS notice. It will tell you what went wrong. Once you understand the problem, gather the correct documents, fill out a new Form W-7, and send the complete package back to the IRS.
Acting quickly is important, especially with a tax deadline approaching or other financial matters pending.
What Is the Difference Between Rejection and Suspension?#
The difference between rejection and suspension is critical. A rejection is final, while a suspension is a request for more information.
* A rejection means the IRS has closed your application. It is a definite "no." You must start the process over with a new Form W-7 and all supporting documents.
* A suspension is a "pause." This usually arrives as an IRS notice called a CP566. It means the IRS needs clarification. They will give you a deadline, typically 45 days, to send the requested information. Your application gets back on track, if you meet that deadline. The application gets officially rejected if you miss it, and you must start over.
