Any grant or stipend amount awarded in excess of tuition, required fees, books, and supplies is subject to federal income tax, as is any funding contingent upon providing service to the University (for example, teaching fellowships or research assistantships). Income taxes are not ordinarily withheld from stipend payments; be sure to incorporate this tax obligation into your financial planning.
