Moved from Missouri to Michigan Mid-Year: Which State Tax Returns Do You File?

Two part-year returnsBoth states claim the income

Answer

Expect a part-year filing on each side. The point of a part-year return is that neither state taxes the whole year, so you are not double-taxed by default — but income received close to the move date has to be assigned carefully, and a lingering Missouri source can still pull a nonresident filing along with it.

Part-year returns are designed so that neither state taxes the whole year. The risk is not double taxation by default; it is misassigning income received near the move date, and losing the proration on deductions and credits.

Questions people actually ask

I moved from Missouri to Michigan mid-year. Do I have to file in both states?

Expect a part-year filing on each side. The point of a part-year return is that neither state taxes the whole year, so you are not double-taxed by default — but income received close to the move date has to be assigned carefully, and a lingering Missouri source can still pull a nonresident filing along with it.

How do I split my income between Missouri and Michigan?

By when you received it, measured against the date your domicile actually changed. Income received while you were a Missouri resident belongs on the Missouri return and income received afterwards on the Michigan return, with each state prorating your deductions, exemptions and credits to its own part of the year. Keep evidence of the move date — a lease, a closing statement, a licence issue date.
