An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service (IRS). ITINs are for federal tax reporting only, and are not intended to serve any other purpose. 
Since ITIN matters are tax-related matters, the International Students & Programs Office (ISPO) cannot offer specific ITIN advice, because our advisors are not licensed tax professionals. However, ISPO put together this page to provide some basic ITIN guidance for international students.

Introduction to ITIN:

Learn About ITIN

The following information is taken from the IRS website:

  • IRS issues ITINs to help individuals comply with the U.S. tax laws, and to provide a means to efficiently process and account for tax returns and payments for those not eligible for Social Security Numbers (SSNs)
  • If you are not eligible for a SSN because you will not work in the U.S., then applying for an Individual Taxpayer Identification Number (ITIN) may be a viable option for you. This will provide you with an identification number for tax purposes in the U.S.
  • Note: An ITIN does not authorize work in the US or provide eligibility for Social Security benefits or the Earned Income Tax Credit
  • For more information, download an ITIN guide from the IRS website

Check Your ITIN Eligibility

If you do not have a SSN and are not eligible to obtain a SSN, but you have a requirement to furnish a federal tax identification number or file a federal income tax return, you must apply for an ITIN. If you have an application for a SSN pending, do not file Form W-7. Complete Form W-7 only if the Social Security Administration (SSA) notifies you that a SSN cannot be issued.
