Taxpayer ID

An Individual Taxpayer Identification Number (ITIN) is a tax processing number issued by the Internal Revenue Service (IRS) not the Social Security Administration. 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 from the Social Security Administration. ITINs are for federal tax reporting purposes only. To find out more about ITIN numbers, please visit Internal Revenue Service.

In order to apply for an ITIN number, please download the Application for IRS Individual Taxpayer Identification Number. You also need to come to International Affairs during advising hours and pick up a letter of support to include in your ITIN application.

Once you have received your ITIN number, please report this number to:

  • Glacier: Log in to your Glacier profile and update your number. Print, sign and send the Glacier forms to the email provided.
  • Ohio State Human Resources: Log into your Ohio State Workday account and update your number. Read instructions. If you have any questions, email HRConnection@osu.edu.
