Michigan's residency tests
You're a Michigan resident if either applies:
- Domicile-based: Michigan is your domicile.
- Statutory residence: you maintain a place of abode in Michigan AND spend more than 183 days there.
What counts as a Michigan day
Any presence on a calendar day counts. Days at DTW airport may count if you cleared TSA on an MI-origin flight.
Departing Michigan
- Establish new-state domicile with the standard checklist.
- Sever MI home if possible.
- Update voter registration, driver's license, vehicle registration.
- Move family if applicable.

Frequently asked questions
How many days can I spend in Michigan without becoming a tax resident?
Michigan's statutory residence test generally requires two things together: maintaining a place of abode in Michigan and spending more than 183 days there. Staying at or below 183 Michigan days typically keeps you outside the statutory test, but you can still be taxed as a resident if Michigan remains your domicile.
What is Michigan's income tax rate?
Michigan has a 4.25% flat income tax. That is modest compared with Northeastern states, but it is generally still enough to motivate high earners to move to lower-tax states.
Does a layover at Detroit airport count as a Michigan day?
Any presence in Michigan on a calendar day generally counts toward the day count. Days spent at DTW may count if you cleared TSA on a flight that originated in Michigan, so treat airport time as a potential Michigan day rather than assuming it is excluded.
How do I stop being a Michigan resident for tax purposes?
The typical playbook is to establish domicile in your new state, sever your Michigan home if possible, and update your voter registration, driver's license, and vehicle registration. Moving your family, if applicable, and tracking your Michigan days from the move date forward generally strengthen the case in a Michigan Department of Treasury audit.
