What Is ITIN?
ITIN stands for Individual Taxpayer Identification Number. It is an alternative to a Social Security number for individuals who do not qualify for a Social Security number but are required to file taxes in the U.S.
Who Needs an ITIN?
You will need an ITIN if you have to file a federal tax return but aren’t eligible to obtain a Social Security number. According to the IRS, this may include:
- Nonresidents who have income or investments from the U.S. and need to file a tax return
- U.S. residents who are not U.S. citizens but are filing a tax return
- Dependents or spouses of U.S. citizens who do not qualify for an SSN
- Dependents or spouses of nonresident visa holders
- Nonresident/non-citizen claiming a tax treaty benefit
- Nonresident/non-citizen student, professor or researcher filing a U.S. tax return or claiming an exemption
How To Obtain an ITIN: 3 Best Methods
The IRS makes it easy to obtain an ITIN in person or by mail. If your application is approved, the IRS says it typically takes up to seven weeks to receive a letter with your new ITIN. You should apply for an ITIN before the federal tax deadline of April 18, 2023, to avoid any penalties if you owe taxes. Your W-7 form, which is your application for an ITIN, should be attached to your U.S. federal tax return when you submit it.
When you’re applying for an ITIN, you will need to submit original documentation showing your proof of identity and foreign status. You may also be able to submit certified copies from the issuing agency that originally provided the documentation.
You should submit your W-7, documentation, and federal tax returns together. Gather this paperwork first, and then determine whether you’d like to apply by mail or in person.
1. Apply for an ITIN by Mail
If you opt to submit your documentation and W-7 form by mail, send it to:
Internal Revenue Service
Austin Service Center
P.O. Box 149342
Austin, TX 78714-9342
The documents submitted will be returned to you within 14 weeks. If you need them sooner, you might prefer to apply for your ITIN in person.
2. Apply for an ITIN through a TAC
A Taxpayer Assistance Center (TAC) will have staff available to help people file their federal tax returns and apply for an ITIN, if necessary. TACs are located in many cities across the U.S. Multilingual assistance is offered at all locations.
To find a center near you and schedule an appointment, you can visit the IRS TAC location website. Make sure to bring all your paperwork, including any information you may need for filing your tax returns. TACs can also help you file your returns properly to ensure you are getting any credits and deductions you deserve.
3. Apply for an ITIN Through a CAA
A Certifying Acceptance Agent (CAA) can also help walk you through the process of applying for an ITIN and filing your taxes. Through the Volunteer Income Tax Assistance program, you may also be eligible to receive free tax prep services at a CAA near you. You can find a center on the IRS website.
An ITIN makes it possible to file your U.S. income taxes, even if you are not eligible to work in the U.S. or obtain a Social Security number.
