North Dakota 183-Day Rule Checker
North Dakota runs a statutory day-count test at 210 days. Enter your days or build date ranges below for a verdict cited to North Dakota's actual rule.
North Dakota's actual test
North Dakota's day-count threshold is unusually high: an individual who maintains a home in North Dakota and is present in the state for more than 210 days (seven months) of the tax year is treated as a full-year resident, per North Dakota Century Code ch. 57-38 and the Tax Commissioner's residency guidance. This is 27 days more lenient than the 183-day standard used by most neighboring high-tax states.
Any part of a day
Not explicitly published by the Tax Commissioner for the 210-day test; third-party residency-tracking guides advise treating arrival days, departure days, and any same-day presence as a full North Dakota day out of caution, consistent with how most other statutory-residency states count.
Methodology and sources
The threshold, presumption, and rule text shown here come directly from North Dakota's researched dossier, reviewed against 8 primary sources including North Dakota Office of State Tax Commissioner. This is general information, not tax or legal advice.

0 days is comfortably under the 210-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.

North Dakota Day-Count FAQ
Is North Dakota's residency day count really 210 days instead of 183?+
Yes. North Dakota's statutory-residency test triggers when someone maintains a home in the state and is present more than 210 days (about seven months) in the tax year, a higher bar than the 183-day threshold most other states use. Domicile still controls independently: someone who is actually domiciled in North Dakota is a resident regardless of day count.
Do I need to register to vote before I can claim North Dakota residency?+
No. North Dakota is the only state with no voter registration system at all. To vote you show up at your polling place with an accepted photo ID (ND driver's license, non-driver ID, or tribal ID) after having lived in the state for 30 days before Election Day. That makes voter rolls useless as domicile evidence here, unlike in most other states.
I work in North Dakota but live in Minnesota. Do I owe North Dakota income tax?+
Not if you qualify for the Minnesota-North Dakota reciprocity agreement: file Form NDW-R with your employer so North Dakota does not withhold, and pay tax to Minnesota instead. Minnesota also requires you to return to your Minnesota home at least once a month to keep the exemption; the form has to be renewed annually.
How long do I have to get a North Dakota driver's license and register my car after moving here?+
You have 60 days to transfer your driver's license (30 days if it's a commercial license) and 90 days to register your vehicle with the NDDOT Motor Vehicle Division. You need North Dakota-compliant insurance in place before the vehicle will be registered.
I'm a travel nurse working Bakken-region hospital contracts. Does North Dakota have special tax-home rules for me?+
No. North Dakota has no nurse-specific tax-home guidance; the general IRS tax-home rules under Publication 463 govern whether your stipends stay tax-free, and North Dakota's own residency status turns on the same domicile or 210-day tests that apply to everyone else. Keep your permanent-home evidence (lease or ownership, returning between assignments) regardless of which state you call your tax home.
