Individual Tax Payer Identification Number (ITIN)

An Individual Tax Payer 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. 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.

HIO instructions to complete the application form W-7 may be found here.

ITINs are required for family members who do not have SSNs and are being claimed as tax dependents on a student's or scholar's annual state tax filing.

Note: Do not send your passport away for an ITIN application.

Possible Identification Issues

ITIN applications normally require submission of the original passport. An exemption to this requirement allows those with a SEVIS record to submit a letter from the HIO certifying the applicant’s identity. Unfortunately, some of the ITIN Operations Center adjudicators do not apply this exemption. The only solution for this is to reapply with the same materials and the HIO letter. Please follow the instructions linked above to compile your application before coming to the HIO for the certification letter.

What to do Upon Receipt of the ITIN

  1. Login to your Harvard Glacier account
  2. Input the ITIN
  3. Print the new Glacier Summary sheet
  4. Take the Glacier Summary and ITIN notice to the Harvard Office of the Controller. The address will be printed on the Glacier Summary.

Non-Students

Individuals sometimes want to obtain ITINs for family members. The ITIN might be helpful in claiming state tax benefits and credits. Please review the IRS's ITIN application instructions to determine if, or how, your dependents might qualify for an ITIN.

Social Security Numbers (SSN) and ITINs

At some point, ITIN holders may obtain an SSN for employment in the U.S. Once you receive your SSN, you must then link the two numbers. Please find the below information directly from the IRS:

What do I do when I am assigned a social security number (SSN)?

Once you receive a SSN, you must use that number for tax purposes and discontinue using your ITIN.  It is improper to use both the ITIN and the SSN assigned to the same person to file tax returns.  It is your responsibility to notify the IRS so we can combine all of your tax records under one identification number.  If you do not notify the IRS when you are assigned a SSN, you may not receive credit for all wages paid and taxes withheld which could reduce the amount of any refund due.  You can visit a local IRS office or write a letter explaining that you have now been assigned a SSN and want your tax records combined.  Include your complete name, mailing address, and ITIN along with a copy of your social security card and a copy of the CP 565, Notice of ITIN Assignment, if available.  The IRS will void the ITIN and associate all prior tax information filed under the ITIN with the SSN.  Send your letter to:
