How much tax will I be charged?

If you are a U.S. citizen Harvard will not withhold taxes from your taxable scholarship or stipend. If you are a foreign student, the taxable portion of your award will be taxed at a rate of 14%.

Some foreign students come from countries that have a tax treaty with the United States, and can claim exemption from U.S. taxes. International students receiving taxable scholarships from Harvard will receive an e-mail from the Student Accounts Office which will include information about your tax status and tax treaties. If you have questions about your eligibility, you can contact the Student Accounts Office. Although the tax treaty may exempt your scholarship from tax, you may still be required to file an income tax return.
