Individual Tax Identification Numbers (ITIN)
Summary
This page provides information for Harvard international students and scholars about applying for an Individual Tax Identification Number, also referred to as an ITIN.
*The HIO is not accepting ITIN applications at this time; additional information about a new ITIN application process is forthcoming. Please check back here for details in late summer/early fall 2026.*
An Individual Taxpayer Identification Number (ITIN) is required for international students who do not have a Social Security Number (SSN) but are receiving grants, fellowships and scholarships from Harvard. Please note: You do not need an ITIN if the amount of your fellowship and grant income is less than the cost of tuition as listed on your I-20 form. An ITIN is used by Harvard to report the amount of a student's funding to the U.S. Internal Revenue Service (IRS). Harvard also uses the ITIN for the annual statement issued to you that reflects the funding information reported to the IRS.
