Individual Taxpayer Identification Number (ITIN)

Last Updated: January 10, 2024

What is an ITIN?

According to the IRS website: An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service. The IRS issues ITINs to individuals who are required to have a U.S. taxpayer identification number but who do not have, and are not eligible to obtain, a Social Security number (SSN) from the Social Security Administration (SSA).

Am I eligible?

The IRS provides specific reasons for needing an ITIN, listed below. If you meet the eligibility for b, c, d, e, f or g, you must file a U.S. federal tax return with your W-7 unless you meet one of the exceptions (see W-7 instructions). Most students usually need an ITIN for a scholarship, fellowship or grant, and qualify for an exception, and therefore do not need to include a completed a tax return with their application.

  1. Nonresident alien required to get an ITIN to claim a tax treaty benefit
  2. Nonresident alien filing a U.S. federal tax return
  3. U.S. resident alien (based on days present int he United States) filing a U.S. federal tax return
