North Dakota residency rules

How many days can you spend in North Dakota before you’re a resident?

Q: How many days can you spend in North Dakota before you’re a resident?

Anyone who spends more than seven months of the year in North Dakota and maintains a place to live there is a resident, even with a permanent home elsewhere. That is roughly 210 days.

More than seven months. North Dakota treats you as a resident once you spend more than seven months of the year in the state and keep a place to live there, even if your permanent home is somewhere else. That is roughly 210 days.

The rule in North Dakota

North Dakota treats you as a resident if you maintain a permanent place of abode in the state and spend more than seven months of the tax year there in total, which the Tax Commissioner equates to more than 210 days. No official rule on partial days was found.

Two people can have the same permanent home in another state and get different answers, purely on days. Keeping the count below the line, and being able to prove it, is the entire game.

How long do you have to live in North Dakota to be considered a resident?

Two ways. You become a North Dakota resident the day you make it your domicile, however few days you have spent there. Or, even with a permanent home elsewhere, you are treated as a resident once you reach more than seven months in North Dakota in a single year while keeping a place to live there. The second route is the one that catches people by surprise.

North Dakota residency requirements for taxes

North Dakota looks at domicile first, then at days. Domicile is where your permanent home is, judged on the facts below. On top of that, the day-count rule above can make you a resident regardless of domicile.

Where your permanent home is, and where you spend more of your nights
Driver’s licence, vehicle registration, and voter registration
Where your spouse, children, and pets live and go to school
Where your doctor, dentist, accountant, and bank are
Where the things you would not want to lose are kept
Day counts, which are the one factor the state can verify independently

What counts as a day

In most states any part of a day spent in the state counts as a full day, including the day you arrive and the day you leave. Layovers and driving through can count too. A few states exempt time in transit or days spent in a hospital, but the safe assumption is that if you were there at any point, the day counts.

The count is per calendar year and resets on January 1. Days do not have to be consecutive.

How North Dakota checks

The burden of proof is on you, not the state. In a residency audit the state asks for the records that show where you physically were, day by day:

Mobile phone location and call records
Credit and debit card transactions
Flight itineraries, toll records, and parking receipts
Calendar entries, social media posts, and photos with location data

Gaps in your records are usually resolved against you. A day you cannot place somewhere else is a day the state can argue you spent inside it.
