You can fill out the IRS Form W-7, Application for IRS Individual Taxpayer Identification Number (ITIN), by carefully completing each section, gathering necessary supporting documents, and submitting the application package through an authorized channel. This process is essential for non-residents and foreign nationals who need a U.S. taxpayer identification number for tax purposes but are ineligible for a Social Security number.
This guide will walk you through the intricacies of how to fill out the ITIN application, covering everything from understanding the eligibility requirements to submitting your completed application. It is vital to ensure accuracy and completeness to avoid delays in processing.
Who is Eligible for an ITIN?
An ITIN is issued by the IRS to individuals who need a U.S. taxpayer identification number but do not have and are not eligible to obtain a Social Security number (SSN). This includes:
- Non-resident aliens filing a U.S. federal tax return.
- U.S. resident aliens (based on days present in the U.S.) who are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens who are not eligible for an SSN.
- Dependents or spouses of non-resident alien visa holders who are not eligible for an SSN.
- Individuals applying for tax treaty benefits.
Eligibility is primarily tied to a U.S. tax reporting requirement or the need to claim tax treaty benefits. Simply wanting an ITIN for banking or business purposes without a tax filing obligation is generally not sufficient grounds for issuance. The IRS will verify that you have a valid reason for needing an ITIN before issuing one.
What Documents Are Required for an ITIN Application?
To successfully apply for an ITIN, you must submit a completed Form W-7 along with original or certified copies of specific identification documents. The IRS requires proof of identity and foreign status. You will need to provide:
- Form W-7, Application for IRS Individual Taxpayer Identification Number: This is the core application form. Ensure all fields are completed accurately. Missing information is a common reason for delays.
- Original or Certified Copy of a Federal Tax Return: Most applicants must attach a valid U.S. federal income tax return for the year they are requesting the ITIN. If you are claiming an exception, you must attach documentation supporting that exception.
- Original or Certified Copy of Identification Documents: You must provide one of the following documents that shows your name, photograph, current address, and nationality:
- Passport
- National Identity Card (must contain photo, name, address, DOB, and expiration date)
- U.S. Driver's License
- Foreign Driver's License
- U.S. State Driver's License
- Foreign Military Identification Card
- U.S. Military Identification Card
- Visa
- U.S. Permanent Resident Card (Green Card)
- Civil Birth Certificate (for individuals under 18)
- National Health Insurance Card (with photo)
- Foreign Voter's Registration Card
If your primary identification document does not contain a current U.S. address, you must provide a secondary identification document that does. If the name on your identification documents differs from the name on your tax return (e.g., due to marriage or adoption), you must submit legal name change documents, such as a marriage certificate or court order.
Important Note on Documentation: The IRS will return your original identification documents by mail. If you cannot afford to mail original documents, you can use the services of a Certified Acceptance Agent (CAA). CAAs are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. They can verify your original documents and send certified copies to the IRS, meaning you retain your originals. itin.net is an authorized CAA service.
How to Fill Out Form W-7: Section by Section
Filling out Form W-7 requires attention to detail. Here’s a breakdown of each section:
Section 1: Applicant Information
- Name: Enter your legal name exactly as it appears on your identification documents. If you have changed your name, you must also submit legal documentation of the name change.
- Social Security Number: If you have ever been issued an SSN, even if you are not eligible to work in the U.S., you must enter it here. Failure to disclose an SSN can result in the rejection of your W-7 application. If you have never been issued an SSN, leave this blank.
- Mailing Address and Foreign Address: Provide a complete mailing address where the IRS can send correspondence, including your ITIN. You can also provide a foreign mailing address if applicable.
- City, State, Zip Code, Country: Fill in these details for both your U.S. and foreign addresses.
- Telephone Number: Include your primary phone number.
- Email Address: Provide your email address for electronic communication.
- Date of Birth: Enter your date of birth in the MM/DD/YYYY format.
- Place of Birth: Enter the city and country of your birth.
- Country of Citizenship: Enter your country of citizenship.
- Marital Status: Select your current marital status.
Section 2: Reason for Applying
This section is critical. You must check the box that corresponds to your reason for applying for an ITIN. Common reasons include:
- Box a: To claim an exception to the ITIN requirement and claim treaty benefits on a U.S. tax return.
- Box b: To file a U.S. tax return as a non-resident alien (this is the most common reason).
- Box c: To file a U.S. tax return as a resident alien (if you are not eligible for an SSN).
- Box d: As a dependent or third-party designee.
- Box e: For use by a third-party designee.
If you are applying based on a tax return filing requirement, you must attach that tax return. If you are applying to claim tax treaty benefits, you will need to provide details about the treaty and the income involved.
Section 3: Identification Documents
- Type of Identification: Select the primary identification document you are submitting (e.g., Passport, National Identity Card).
- Issuing Authority: Enter the name of the agency that issued your identification document.
- Expiration Date: Provide the expiration date of your identification document.
- Country: Enter the country that issued your identification document.
If you are submitting a secondary identification document, you will provide similar information for that document as well.
Section 4: Applicant's Signature
- Signature: Sign and date the form. This must be your legal signature.
- Printed Name: Print your name clearly below your signature.
Section 5: Third-Party Designee (Optional)
This section allows you to designate another person (like a tax preparer or agent) to receive your ITIN information from the IRS. If you choose to designate someone, they will need to sign and date this section. This is often used when working with tax professionals.
Section 6: Certification
This section is typically completed by the acceptance agent (like itin.net) or by the IRS employee if you apply in person at an IRS Taxpayer Assistance Center (TAC). It certifies that the identification documents presented are authentic or have been verified. Do not fill this out yourself if you are applying directly to the IRS or through a CAA.
How to Submit Your ITIN Application
Once your Form W-7 is complete and you have gathered all supporting documentation, you have several options for submission:
Mail Directly to the IRS: You can mail your completed Form W-7, along with your original or certified identification documents and a copy of your federal tax return, to the IRS address specified in the Form W-7 instructions. The IRS will review your application and mail your ITIN back to you, along with your original documents. This method can take longer due to mail transit times and IRS processing.
Apply Through a Certified Acceptance Agent (CAA): This is often the most convenient and secure method. You can visit an authorized CAA, such as itin.net. A CAA will review your application, verify your original identification documents (meaning you keep your originals), and transmit the application package to the IRS on your behalf. This can often expedite the process and provides an added layer of verification. The CAA will then receive confirmation from the IRS regarding your ITIN. Applying through a CAA is a popular choice for those who want to ensure their documents are handled correctly and returned promptly.
Apply at an IRS Taxpayer Assistance Center (TAC): You can make an appointment at an IRS TAC that offers ITIN application services. You will need to bring your completed Form W-7, your original identification documents, and your tax return. The IRS staff will review your documents and application on-site. However, TACs have limited availability and can be difficult to schedule, especially during peak tax seasons.
Processing Time:
- Direct Mail to IRS: The IRS states that processing can take up to 11 weeks from the date they receive your application. This does not include mailing times to and from the IRS.
- Via CAA or TAC: Applications processed through CAAs or TACs are generally expedited. The IRS typically processes these applications within 4–6 weeks. Again, this timeframe is from when the IRS receives the application, not from when you first submit it to the CAA or TAC.
Cost and Fees
There is no fee charged by the IRS to apply for an ITIN. The Form W-7 application itself is free. However, if you use the services of a Certified Acceptance Agent (CAA) like itin.net, they may charge a service fee for their assistance in reviewing and submitting your application. This fee covers the agent's time, expertise, and the administrative costs associated with the service. If you choose to mail your application directly to the IRS, you will only incur postage costs. If you use a tax preparer who is not a CAA, they may also charge a fee for preparing your tax return and assisting with the W-7.
Common Mistakes to Avoid
Many applicants encounter delays or rejections due to common mistakes. Be sure to avoid the following:
- Incomplete Application: Missing information on Form W-7 is the most frequent issue. Double-check every field.
- Incorrect Identification Documents: Not providing the correct type of identification or failing to submit original or certified copies can lead to rejection. Ensure your documents meet IRS requirements.
- Missing Tax Return: Forgetting to attach the required federal tax return is a common oversight. Ensure it is signed and dated.
- Incorrect Reason for Application: Checking the wrong box in Section 2 can cause your application to be denied if you don't meet the criteria for the selected reason.
- Name Mismatches: If your name on your identification differs from your name on your tax return, you must include legal documentation proving the name change.
- Not Disclosing SSN: If you have ever been issued an SSN, you must report it on the W-7. Failure to do so is grounds for rejection.
- Outdated Forms: Ensure you are using the most current version of Form W-7 and its instructions, available on the IRS website.
- Submitting Photocopies Instead of Originals/Certified Copies: Unless you are using a CAA or TAC, you must submit original identification documents or certified copies from the issuing agency. The IRS will mail your originals back.
What Happens After You Get Your ITIN?
Once your ITIN application is approved, the IRS will mail you a Form W-7, CP565, ITIN Assignment Letter, which contains your unique ITIN. This letter is important, so keep it in a safe place. You will need your ITIN for:
- Filing Future Tax Returns: You must use this ITIN on all future U.S. federal tax returns and other tax documents. For example, if you are forming a U.S. LLC, you will likely need an ITIN to file Form 5472 if you are a single-member LLC owned by a foreign individual.
- Opening a U.S. Bank Account: While some banks may allow opening an account with just a foreign passport, many U.S. financial institutions require an ITIN or SSN for account opening. This can be crucial for managing business finances, especially if you plan to open a U.S. bank account.
- Claiming Tax Treaty Benefits: If you applied for an ITIN to claim benefits under a tax treaty, you will use your ITIN when filing your tax return to claim those benefits.
ITIN Renewal:
ITINs do not expire unless they are not used on a federal tax return for three consecutive tax years. However, the IRS has implemented a renewal program for ITINs with the first four digits of 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, or 93. If your ITIN falls within these ranges, and you need to use it for tax purposes, you must renew it. The renewal process is similar to the initial application, requiring a completed Form W-7 and updated identification documents, but you do not need to submit a tax return with the renewal application unless you are claiming treaty benefits.
How to Get Help with Your ITIN Application
Navigating the ITIN application process can be complex. If you are unsure about any step or want to ensure accuracy and avoid potential delays, consider these options:

For individuals planning to establish a U.S. business presence, obtaining an ITIN is often a preliminary step before applying for an Employer Identification Number (EIN) using Form SS-4, which is necessary for most business operations, including opening bank accounts and hiring employees. You can find more information on our EIN application service page. Establishing a U.S. LLC is another common step for foreign nationals conducting business in the U.S., and this often requires an ITIN and an EIN. Learn more about forming a U.S. LLC.
