You apply for an ITIN by submitting Form W-7, Application for IRS Individual Taxpayer Identification Number, along with original or certified copies of identity documents and a U.S. federal income tax return, to the IRS. This process is the official way to obtain an ITIN for tax purposes in the United States.
Applying Directly to the IRS
You can mail your completed Form W-7 and supporting documents directly to the IRS. This is often referred to as the "direct filing" method. The IRS will review your application, verify your documents, and issue you an ITIN if approved. Your original documents will be mailed back to you, usually within 60 days, though processing times can vary. You must include a U.S. federal income tax return with your Form W-7 application, unless you qualify for an exception. The exception categories are detailed in the Form W-7 instructions and include situations like needing an ITIN to claim tax treaty benefits or to comply with IRS withholding requirements.
Applying Through a Certified Acceptance Agent (CAA)
An alternative to mailing your application directly to the IRS is to use a Certified Acceptance Agent (CAA). A CAA is an individual or entity authorized by the IRS to help taxpayers apply for ITINs. This method is often preferred because CAAs can review your documentation, authenticate your original identification documents, and forward your application to the IRS on your behalf. The primary benefit of using a CAA is that they can certify your original identification documents, meaning you do not have to mail them to the IRS and risk losing them. The IRS typically returns certified documents to the applicant within 7 to 10 weeks. Many individuals and businesses find this path more convenient and secure. The itin.net service acts as a facilitator to connect individuals with CAAs, streamlining the process.
Who Needs an ITIN?
An ITIN is for individuals who are required to have a U.S. taxpayer identification number but do not have, and are not eligible to obtain, a Social Security number (SSN). This includes resident and non-resident aliens, their spouses, and dependents who cannot get an SSN, as well as others who need a U.S. tax identification number for specific tax purposes. Common reasons for needing an ITIN include filing a U.S. federal tax return, claiming tax treaty benefits, or complying with IRS requirements for withholding and information reporting. For instance, if you are a foreign national earning U.S. source income, you may need an ITIN. If you are forming a U.S. LLC, an ITIN might be necessary for certain tax filings, such as Form 5472 for reporting transactions with a foreign owner, or if you plan to open a U.S. bank account without an SSN.
Required Documentation
To apply for an ITIN, you must submit Form W-7 along with original or certified copies of documentation proving your identity and foreign status. The IRS requires proof of your identity and your claim of foreign status. You can satisfy this requirement with one original or certified copy of one document from List A (proof of identity and foreign status) or one original or certified copy from List B (proof of identity) and one original or certified copy from List C (proof of foreign status).
Acceptable documents include, but are not limited to:

- If your documentation is in a foreign language, you must provide a certified English translation.
- The IRS prefers original documents or certified copies from the issuing agency. If you use a CAA, they can certify your documents for you.
The Tax Return Requirement
As mentioned, most applicants must submit a U.S. federal income tax return with their Form W-7 application. This return must be filed for the tax year for which you are claiming the ITIN. For example, if you are applying for an ITIN in 2024 to file your 2023 tax return, you would include your completed 2023 tax return with your Form W-7. The tax return serves as the primary reason for needing an ITIN. If you are filing a joint return, your spouse's SSN must be included if they have one. If you are a dependent, your application must be associated with the return of the person claiming you as a dependent.
Exceptions to the Tax Return Requirement
There are specific circumstances where you do not need to include a tax return with your Form W-7. These exceptions are detailed in the Form W-7 instructions and include:
- Withholding Certificates: If you are claiming tax treaty benefits or requesting reduced rate of withholding on U.S. source income, you may use Form W-7 without a tax return. You will typically need to attach Form(s) W-8BEN, W-8ECI, or other applicable withholding forms.
- Third-Party Payments: If you are receiving certain third-party payments that are subject to U.S. tax reporting and withholding.
- Dependents and Spouses of U.S. Citizens/Resident Aliens: If you are a dependent or spouse of a U.S. citizen or resident alien and are not eligible to obtain an SSN.
- Nonresident Alien Spouse Claiming Treaty Benefits: A nonresident alien spouse filing a joint return with a U.S. citizen or resident alien spouse who is claiming treaty benefits.
- Dependents or Third Parties: If you are a dependent or third-party designee of a taxpayer who is required to obtain an ITIN for the dependent or designee to comply with U.S. tax laws.
- ITIN Renewal: While not an initial application, ITINs do expire and may need renewal under specific IRS guidelines.
Processing Times and Costs
There is no fee to apply for an ITIN directly with the IRS. However, using a Certified Acceptance Agent (CAA) may involve fees charged by the agent for their services. The IRS processing time for Form W-7 applications can vary significantly. Historically, it has taken anywhere from 4 to 11 weeks to receive an ITIN when applying directly to the IRS, especially during peak tax filing seasons. If you apply through a CAA, the initial document verification by the agent is immediate, but the IRS processing time after they forward your application remains similar. The IRS may take longer if your application is incomplete or if they require additional documentation. It is advisable to apply well in advance of any tax deadlines.
Common Mistakes to Avoid
Several common mistakes can delay or result in the denial of your ITIN application. Understanding these pitfalls can significantly improve your chances of a smooth process.
- Incomplete Form W-7: Ensure all fields are filled out accurately and completely. Missing information is a primary reason for delays.
- Incorrect or Missing Documentation: Failing to provide the required original or certified identification documents, or providing expired or incorrect documents, is a frequent issue. Ensure your documents meet the IRS criteria.
- Not Submitting a Tax Return (When Required): If you don't qualify for an exception, omitting the U.S. federal income tax return will lead to denial. The tax return is the primary justification for needing an ITIN.
- Incorrectly Certified Documents: If you are not using a CAA, ensure that any certified copies you submit are from the issuing agency itself. Simply notarizing a copy is not sufficient for the IRS.
- Mismatched Information: Ensure the name and address information on your Form W-7 exactly matches the information on your supporting identification documents and your tax return.
- Not Including Translations: If any of your supporting documents are not in English, a certified English translation must be included. The translator must certify the accuracy of the translation and their competence to translate.
What Happens After Approval?
Once your Form W-7 application is approved, the IRS will issue you an ITIN. You will receive an official notice from the IRS, typically a CP-565 notice, which contains your ITIN. This notice is crucial, so keep it in a safe place. Your ITIN is permanent and does not expire unless it is not used on a federal tax return for three consecutive tax years. If your ITIN has not been used for three years, the IRS may deactivate it. You will need to reapply and submit updated documentation if this happens. Your ITIN is essential for filing U.S. tax returns, claiming tax treaty benefits, and for certain other U.S. financial and business activities. For example, if you are establishing a U.S. LLC, you may need an ITIN for various tax-related filings, including Form 5472. If you are looking to open a U.S. bank account, an ITIN can often be used in lieu of an SSN.
Seeking Assistance
While the process of applying for an ITIN can be managed independently, many individuals find assistance helpful. Certified Acceptance Agents (CAAs) are invaluable resources for navigating the complexities of the application. They can pre-screen your application, authenticate your identity documents, and ensure your submission is complete, significantly reducing the risk of errors and delays. If you are unfamiliar with U.S. tax forms or documentation requirements, or if your situation is complex, seeking help from a CAA is highly recommended.
