Individual Taxpayer Identification Number (ITIN)

If you have been awarded a scholarship, fellowship or grant, you are required to file a federal tax return. You may or may not have to pay taxes on your scholarship, fellowship or grant, depending on which country you are from and whether there is a tax treaty between the U.S. and your country.  

For tax purposes, students who are not eligible to receive a Social Security Number must instead get an Individual Taxpayer Identification Number. You cannot have both an ITIN and a SSN. Therefore, once you receive your SSN, (if you get a job on campus or through CPT/OPT), you will have to rescind your ITIN.

An ITIN is a tax processing number issued by the Internal Revenue Service. The IRS issues ITINs to international students who are not eligible to obtain a social security number. An ITIN is not the same as a social security number, and does not offer the same benefits. It is for U.S. federal income tax filing purposes only.

Note: If you already have an ITIN you can ignore this email. If you have applied for an ITIN in the past and have not yet received it, please email ISSS at
