You file for an ITIN number by completing and submitting IRS Form W-7, Application for IRS Individual Taxpayer Identification Number. This form is submitted along with original or certified copies of identification documents and a U.S. federal tax return (or a return with an attached statement explaining why a return is not required). The IRS issues ITINs to individuals who are not eligible for a Social Security number (SSN) but need a U.S. taxpayer identification number for tax purposes. Understanding how to file for an ITIN number correctly is the first step for many non-residents engaging with the U.S. tax system, whether for personal income reporting, business dealings, or other tax obligations.
Who Needs an ITIN?
An ITIN is required for specific tax-related purposes when you are not eligible for an SSN. This includes:
- Non-resident aliens filing a U.S. tax return.
- Resident aliens (based on days present in the U.S.) filing a U.S. tax return.
- 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.
- Individuals who are otherwise required to have a U.S. taxpayer identification number for tax purposes, such as those who need to file Form 5472 to report transactions with a U.S. LLC they own, or to open a U.S. bank account.
If you are unsure about your SSN eligibility, you should first apply for an SSN with the Social Security Administration. If you are denied an SSN, you may then be eligible for an ITIN.
What is Form W-7?
Form W-7 is the primary application form for an ITIN. It collects essential personal information to assign a unique identification number. You will need to provide:
- Your full legal name as shown on your U.S. income tax return.
- Your foreign tax identification number, if you have one.
- Your U.S. mailing address and foreign address.
- Your date of birth and place of birth.
- The reason you are required to have an ITIN (e.g., filing a tax return, claiming treaty benefits, etc.).
Carefully completing each section of Form W-7 is crucial to avoid delays. Any discrepancies or missing information can lead to your application being rejected. The IRS uses the information on Form W-7 to issue your ITIN and to ensure accurate tax processing.
Required Documentation for Form W-7
Submitting valid identification documents is a critical part of the ITIN application process. You must provide original documents or certified copies from the issuing agency that verify your identity and foreign status. The IRS requires at least one document proving both your identity and your age. Common acceptable documents include:
- Passport: This is the preferred document as it proves both identity and nationality. If you submit a passport, you do not need another document to prove age.
- National Identity Card: Must contain your photograph, name, address, date of birth, and expiration date.
- U.S. Driver's License: Must contain your photograph, name, address, date of birth, and expiration date.
- Foreign Driver's License: Must contain your photograph, name, address, date of birth, and expiration date.
- Birth Certificate: Must include your name, date of birth, place of birth, and the issuing agency's seal.
- Foreign Military Identification Card: Must contain your photograph, name, address, date of birth, and expiration date.
- National Health Insurance Card: Must contain your photograph, name, address, date of birth, and expiration date.
- Voter Identification Card: Must contain your photograph, name, address, date of birth, and expiration date.
- Civil Birth Certificate: For individuals under 18, if a passport is not available.
If your identification document does not show your name exactly as it appears on your tax return, you must also submit a secondary document that links the name on your identification document to the name on your tax return. Examples include a marriage certificate or a court order for adoption.
If your documents are not in English, you must provide a certified English translation. The translation must be certified by the translator and include a statement that the translation is accurate and that the translator is competent to translate from the foreign language into English.
How to File Form W-7: The Options
There are three primary methods to submit your Form W-7 application:
1. Filing Directly with the IRS (Mail-in or In-Person Appointment)
You can mail your completed Form W-7, along with your original tax return and supporting identification documents, directly to the IRS at the address specified in the Form W-7 instructions. The IRS will review your application and documents. If approved, they will issue your ITIN and mail your original identification documents back to you. This process can take a significant amount of time, as the IRS processes these applications in batches.
Alternatively, you can make an appointment at an IRS Taxpayer Assistance Center (TAC) that offers ITIN application services. These TACs can verify your original identification documents and forward your application to the ITIN operation. You must call to schedule an appointment, and availability can be limited. Be aware that not all TACs provide this service.
2. Filing Through a Certified Acceptance Agent (CAA)
This is often the most convenient method for many applicants. A Certified Acceptance Agent (CAA) is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. When you apply through a CAA, such as itin.net
- You submit Form W-7 and your supporting identification documents to the CAA.
- The CAA verifies your original identification documents and forwards a certified copy of them to the IRS along with your application. This means your original documents are returned to you immediately, rather than being mailed to the IRS and waiting for their return.
- The CAA acts as an intermediary, ensuring your application is complete and correctly submitted.
Using a CAA can expedite the process and provides peace of mind knowing your original documents are safe. The itin.net service specializes in assisting individuals with their ITIN applications, offering guidance through the documentation and submission steps.
3. Using an Acceptance Agent (Non-CAA)
Acceptance Agents are individuals or entities authorized by the IRS to help taxpayers apply for ITINs, but they are not CAAs. They can assist with the application but cannot certify your identification documents. You would still need to submit original identification documents or certified copies from the issuing agency when using a non-CAA acceptance agent.
What You Need to File Your U.S. Tax Return with Form W-7
To successfully file for an ITIN, you must generally be filing a U.S. federal income tax return. This typically means filing Form 1040-NR, U.S. Nonresident Alien Income Tax Return, if you are a non-resident alien with U.S. source income. If you are a resident alien for tax purposes, you would file Form 1040.
There are exceptions where an ITIN is needed without filing a tax return. These include:
- Claiming tax treaty benefits.
- Filing Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business) if you own a U.S. LLC that is a disregarded entity for U.S. tax purposes and has reportable transactions with its owner. This is a common reason for individuals to seek an ITIN when setting up a business in the U.S. without forming a corporation.
- Applying for an EIN (Employer Identification Number) for a business entity, although often an EIN can be obtained without an ITIN if the responsible party has an SSN or a foreign tax ID.
- Opening a U.S. bank account.
If you are filing a tax return, ensure it is complete and accurate. Any errors on your tax return can delay the processing of your ITIN application.
Processing Times and Costs
The IRS does not charge a fee to apply for an ITIN. The application for Form W-7 is free. However, you may incur costs if you use a Certified Acceptance Agent (CAA) or other third-party service, as they charge for their assistance.
Processing times for ITIN applications can vary significantly. Currently, the IRS estimates the following processing times:
- Mail-in applications: 7 to 11 weeks from the date the IRS receives your application.
- Applications through a CAA: The CAA forwards your application to the IRS, and the IRS processing time is similar to mail-in applications, but you get your documents back faster.
- In-person appointments at a TAC: Processing can be immediate if the TAC can verify your documents on the spot, but the application is then sent for final processing.
These times are estimates and can change based on IRS workload and the complexity of your application. During peak tax filing seasons, processing can take longer.
Common Mistakes to Avoid
When learning how to file for an ITIN number, be aware of common pitfalls that can delay or result in the rejection of your application:
- Incomplete Form W-7: Missing required fields, incorrect personal information (especially name and address), or failing to select the correct reason for applying.
- Incorrect or Missing Documentation: Submitting expired IDs, documents that do not prove both identity and age, or failing to provide certified translations for non-English documents.
- Not Submitting a Tax Return (when required): Applying for an ITIN without attaching a valid U.S. federal tax return, unless you qualify for an exception (like filing Form 5472).
- Using Uncertified Copies: Submitting photocopies of identification documents instead of originals or certified copies from the issuing agency.
- Mismatched Information: Ensuring the name and date of birth on your identification documents precisely match the information on your tax return.
- Outdated Forms: Using an old version of Form W-7. Always download the latest version from the IRS website.
Taking the time to double-check all details and documentation before submission can prevent these common errors.
What Happens After You Get Your ITIN?
Once your ITIN application is approved, the IRS will mail you a CP565 notice, which officially assigns your ITIN. This notice is important for your records. You should keep it in a safe place.
Your ITIN is valid for your lifetime unless you fail to file a tax return for three consecutive tax years, or if it is associated with fraud or other illegal activity. If you do not file a return for three consecutive years, the IRS may revoke your ITIN. If your ITIN is revoked, you will need to reapply.
Remember that an ITIN is for tax purposes only. It does not authorize you to work in the United States, nor does it provide eligibility for Social Security benefits. You will use your ITIN on all U.S. federal tax filings. If you are planning to establish a business in the U.S., an ITIN is often a prerequisite for obtaining an EIN or opening a U.S. bank account, though other documentation might also be required. For instance, setting up a U.S. LLC typically requires an EIN as well.
How to Get Help with Your ITIN Application
Navigating the ITIN application process can be complex, especially for those unfamiliar with U.S. tax procedures. Several resources are available to assist you:

- Certified Acceptance Agents (CAAs): As mentioned earlier, CAAs like itin.net
are authorized by the IRS to assist with ITIN applications. They can help verify your documents and ensure your application is complete, often speeding up the process and safeguarding your original identification. This is a highly recommended path for many applicants.
- Tax Professionals: Enrolled Agents (EAs) or Certified Public Accountants (CPAs) with experience in international tax matters can provide comprehensive assistance with both your ITIN application and your U.S. tax filings.
- IRS Taxpayer Assistance Centers (TACs): While they offer in-person assistance, appointments can be difficult to secure, and not all TACs provide ITIN services.
