Michigan's actual test
MCL 206.18 defines a resident as an individual domiciled in Michigan. The statute then provides a deeming rule: an individual who lives in Michigan at least 183 days during the tax year, or more than half the days of a taxable year shorter than 12 months, is deemed a resident individual domiciled in Michigan for that year, regardless of where they claim their true domicile to be.
Any part of a day
Michigan's statute and administrative guidance count days lived in the state toward the 183-day threshold without a published carve-out for partial days, and practitioners describe Treasury's audit approach as reconstructing actual days present from travel, financial, and utility records once a residency question is raised.
Presumptions
The 183-day rule itself functions as an irrebuttable statutory deeming provision, not merely a rebuttable presumption: MCL 206.18 states a person who meets the day count 'shall be deemed a resident individual domiciled in this state,' which is a stronger statutory hook than a pure facts-and-circumstances presumption.
Methodology and sources
The threshold, presumption, and rule text shown here come directly from Michigan's researched dossier, reviewed against 9 primary sources including Michigan Department of Treasury. This is general information, not tax or legal advice.

0 days is comfortably under the 183-day statutory threshold. The day-count test alone would not make you a statutory resident here at this pace, though domicile and other facts-and-circumstances tests can still apply independently.

Michigan Day-Count FAQ
Does Michigan really deem me a resident just for spending 183 days here, even if I don't consider it my home?+
Yes. MCL 206.18 doesn't just create a presumption, it statutorily deems anyone who lives in Michigan at least 183 days in a tax year to be a resident domiciled in Michigan for that year. That's a stronger legal hook than the rebuttable presumptions some other states use, so if you're trying to avoid Michigan residency, staying meaningfully under 183 days matters more than in states where the threshold is just one factor among several.
How does Detroit's jock tax work for a visiting player who only plays one game?+
Detroit's city income tax uses a duty-day apportionment formula codified in 2017: the athlete's income is allocated based on the ratio of days spent in Detroit for game-related activities to their total duty days for the season. Detroit's version is notably broad, reaching not just players but injured players who travel with the team, coaches, trainers, and other staff required to travel and perform services, which increases the pool of people who owe Detroit tax for a single game weekend against the Lions, Pistons, Tigers, or Red Wings.
What's the deadline to get a Michigan driver's license after I move here?+
Michigan law provides no grace period: you're expected to obtain a Michigan driver's license as soon as you establish residency, rather than within a set number of days as several neighboring states allow. Vehicle registration generally follows within 30 days for standard transfers. Both are worth completing promptly since they also serve as evidence of when your Michigan residency actually began.
