Graduate student funding is typically granted via a fellowship or an assistantship.
A fellowship does not involve work. It is an award you are given. Once your fellowship has been processed, you should be able to see it in your StuInfo account. A fellowship is taxable. You will receive a tax form the University at the end of the year. If you owe MSU any money, MSU will take what you owe directly from this award prior to deposition. If you have federal financial aid, you will want to check to see how this award affects any funding that you receive.
An assistantship is employment. Assistantships include health insurance and tuition waivers.
An important note regarding financial aid and taxes follows. Please note that Michigan State University does not provide tax advice, and if you have any questions you should seek the assistance of a tax professional.
Michigan State University offers the Volunteer Income Tax Assistance (VITA) program to low- to moderate-income (under $53,000). More information on this program is available at: https://www.vita.msu.edu/.
