Minnesota Tax Residency (183-day rule)

Key parameters
Threshold	183 days
Period / Window	Tax year (1 Jan – 31 Dec)
Counting	Any part of a day
Alternative	Domicile
Additional requirements	Year-round residence in Minnesota

This applies to anyone with a year-round home available to them in Minnesota, whichever state they treat as their own. You are a Minnesota resident if either of these applies:

• Domicile — Minnesota is the place you intend to make your home permanently or for an indefinite period. Once established it continues until you act to change it.
• 183-day rule — you spend at least 183 days in Minnesota and you or your spouse rent, own, maintain or occupy a residence in the state.

Minnesota is precise about what that residence must be. It has to be suitable for year-round use and equipped with its own cooking and bathing facilities, which is a narrower and more testable standard than the general "permanent home" language other states use.

The rule does not reach everyone. Military members stationed in the state while permanently residing elsewhere are outside it, as are residents of Michigan and North Dakota under reciprocity arrangements.

• 183 days qualifies, not 184. Minnesota sets the line at at least 183 days, so a count that would fall short in New York or Massachusetts is enough here.
• An unoccupied house still counts. A home that remains habitable year-round meets the standard even where nobody lives in it for months at a time.
• Your spouse's property is enough. The residence limb is satisfied by a home your spouse rents, owns, maintains or occupies, whatever your own name is on.
• A seasonal cabin may fall outside it. The standard is suitability for year-round use with its own cooking and bathing facilities, which a summer-only structure does not meet.
• Reciprocity narrows the reach. Residents of Michigan and North Dakota, and military stationed in the state while permanently residing elsewhere, are outside the day rule.

A resident is taxed on income from all sources while a nonresident pays only on Minnesota-source income, so an error usually surfaces as out-of-state earnings never reported while another state taxed the same income. The Department charges interest from the original due date and adds penalties for filing late and for underpaying, with higher rates where an understatement is treated as deliberate. Professional tax advice is strongly recommended in situations like this.

A lake house and a long summer

You are domiciled in Illinois and own a Minnesota house with full kitchen and bathroom that stays habitable all year, spending about 190 days there. The residence meets the standard and the count passes 183, so you are a resident.

A count that stops just short

You keep a year-round Minnesota home and are in the state for 180 days, traveling for the rest. The residence limb holds but the count falls under 183, so the day rule does not attach for that year.

A property in a spouse's name

Your spouse rents a year-round apartment in Minneapolis while you spend around 185 days in the state on rotating work. A residence maintained by your spouse satisfies the limb, so the rule attaches to you as well.
