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.
If other state taxes are mistakenly withheld, you then have to file a return, for the other state, to get a refund. OH will not give you a credit for what WV withheld.
