Employment compensation, or a salary, is taxed at marginal graduated rates, meaning income earned over certain levels set by the U.S. tax authorities is taxed at progressively higher rates. Please see the section on income tax withholding tables in IRS publication 15 to get an idea of how your salary will be taxed by Harvard.
- If eligible for tax treaty benefits, both nonresident aliens and resident aliens can claim exemption from tax withholding by submitting completed tax treaty exemption forms and attachments to our office.
- Tax withholding can also be adjusted by submitting a completed W-4 and/or M-4 (Federal and State tax withholding allowance forms). Nonresident aliens are required to select the "single" option for marital status and a maximum of 1 allowance when completing the W-4*, while resident aliens face no such restrictions.
* There are Special Withholding Rules for employees from Canada, Korea, Mexico, the Northern Mariana Islands, American Samoa, and students from India.
