No, you do not need to file a MI return. Full time students, who use their parents (or their own) Ohio residence address are covered by the reciprocity agreement.
Ohio has a reciprocal agreement, on wages, with all neighboring states. No state taxes
are withheld or due and you do not normally need to file a return for the other
state (MI, PA, KY, WV, IN). But OH will tax you on your other state income.
