No, you are not required to file a Michigan return if salaries, wages and other employee compensation was your only Michigan income. To claim a refund of any Michigan withholding tax if you are a resident of a reciprocal state (Illinois, Indiana, Kentucky, Minnesota, Ohio, and Wisconsin), you must file an MI-1040, Schedule 1, Schedule NR, and Schedule W.
Scammers are contacting taxpayers while pretending to be from the Michigan Department of Treasury, using out‑of‑state phone numbers. They may request payments or attempt to trick you into providing your bank account information. Always verify the source before sharing any personal or financial details.
