- Nonresident aliens who are applying for certain types of business licenses in the U.S.
How to apply for an ITIN
To apply for an ITIN, you need to complete Form W-7, which is the Application for IRS Individual Taxpayer Identification Number. The form can be downloaded from the IRS website or requested by mail.
When filling out Form W-7, you must provide the following information:
- Reason for applying for an ITIN
- Personal information, such as name, date of birth, and mailing address
- Foreign status and information about your country of residence
- Supporting documentation that proves your identity and foreign status, such as a passport or national identification card
- A federal tax return, if you are applying for an ITIN in order to file a tax return
After completing Form W-7, you must mail it along with your supporting documentation to the IRS. The processing time for ITIN applications can vary, but it typically takes around 7 weeks to receive your ITIN once the IRS has received your application.

How to renew or cancel an ITIN
If your ITIN is set to expire or you no longer need it, you can renew or cancel it by completing Form W-7 again. If you are renewing your ITIN, you must include a federal tax return with your application, unless you qualify for an exception.
To cancel your ITIN, you must fill out Form W-7 and check the box that indicates that you want to cancel your ITIN. You must also explain why you no longer need the ITIN and provide any supporting documentation that is relevant.
It is important to note that if you do not use your ITIN for federal tax purposes for a consecutive period of three years, it will expire automatically. If this happens, you will need to reapply if you need an ITIN again in the future.
