If your stipend is
education related, then you will need to determine if it's taxable.
Non-Taxable Fellowship - A fellowship payment received by a candidate for a degree, also called a “scholarship” payment by the IRS, is not taxable income to the student if it is used only for tuition and required fees and/or course related expenses, such as fees, books, supplies and equipment that are required of all students enrolled in courses. These payments are not taxable income to the student.
Taxable Fellowship – A payment, typically known as a "stipend", used for living and incidental expenses such as room and board, travel, equipment, i.e. computer or other expenses that are not required of all students enrolled in courses. These payments are taxable income to the student.
Please review IRS publication 970, Tax Benefits for Education for additional information - www.irs.gov/pub/irs-pdf/p970.pdf
If the research award is taxable, how much you have to pay in taxes will depend on how you file your tax return. Are you considered a dependent for tax purposes?
