FAQ > If I receive an SSN, can I continue to use my ITIN for tax purposes?

Once you receive employment authorization from the U.S. Citizenship and Immigration Services (USCIS) you can apply for a Social Security Number (SSN). This nine-digit number allows the IRS to combine all your income records for tax purposes. Your Individual Taxpayer Identification Number (ITIN) will no longer be valid or to reinforce your SSN replaces it and now allows you to file taxes and receive credits and refunds. If you are not eligible for an SSN and earn income in the U.S., however, an ITIN is required and a W7 tax form must be filed to obtain it.

What do I need to apply?

You do not need proof of U.S. citizenship, but you must show the appropriate documents required for ITIN applications. A valid (not expired) passport from your country of residence will be requested and either an original passport or a certified copy will be accepted. If you do not have a valid passport, there are other documents that can be used for processing the ITIN application. You must present two documents that together can prove your identity and your status as a foreigner.

Documents used to prove identity:

  • INS-identification with issued photo
  • Visa issued by the U.S. Department of State
  • Driver's license or identification card issued by any U.S. state
  • U.S. military or national identification card
  • Civil birth certificate
  • Foreign driver's license or military identification card
  • Proof of foreign voter registration

Documents accrediting the State of Foreign Affairs:

  • INS-identification with issued photo
  • Visa issued by the U.S. Department of State
  • Identification card issued by any U.S. state
  • Civil birth certificate
  • The national or military card abroad ID
  • Proof of foreign voter registration

Where to send the W7 form:

  • Internal Revenue Service
    Austin Service Center
