Moving from North Dakota to New York: Residency, Taxes, and What to Prove
North Dakota's 2.50% top income tax rate becomes 10.9% (state); NYC residents add up to 3.876% city tax in New York. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
North Dakota uses a 210-day statutory residency threshold, while New York uses 183 days. Track both thresholds separately during a transition year rather than assuming they line up.
| Factor | North Dakota | New York |
|---|---|---|
| Statutory Residency 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. | Tax Law §605(b)(1)(B): a person not domiciled in New York is still taxed as a statutory resident on worldwide income if they (1) maintain a permanent place of abode in New York for substantially all of the taxable year and (2) spend more than 183 days of the taxable year in New York. Both prongs must be met; exactly 183 days does not trigger the test. |
| Domicile Test | North Dakota treats a person who 'lives in North Dakota full time' as a resident outright; the Tax Commissioner's published guidance focuses on physical presence and home maintenance rather than publishing a detailed multi-factor domicile-intent test the way New York or California do. In practice, practitioners still look to the general common-law domicile factors (permanent home, driver's license, voter registration, family location) when a taxpayer's status is contested. | New York's Nonresident Audit Guidelines and the Tax Department's own analysts weigh five primary factors: the size, cost, and use of the home in each location; time spent in each location; the location of active business involvement; the location of near and dear personal items; and where family (spouse and minor children) live. No single factor controls; the inquiry is a facts-and-circumstances read on genuine intent, per Hodgson Russ's published residency audit guidance. |
| Day Count Threshold | 210 days | 183 days |
| Any Part of a Day Rule | 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. | Yes. Under 20 NYCRR 105.20, presence in New York for any part of a calendar day counts as a full day, including a layover, a lunch meeting, or landing after midnight. Narrow exceptions exist for people in New York solely for medical treatment or solely passing through en route to somewhere outside the state, but there is no general travel-through carve-out. |
| Presumptions | None published | There is no separate day-count presumption beyond the two-prong statutory test itself. Since 2022, Tax Department audit guidelines define 'substantially all of the taxable year' for the permanent-place-of-abode prong as a period exceeding 10 months (previously 11 months), which makes it slightly easier for a part-year abode to fall outside the test. |
| Safe Harbors | Reciprocity exemption (Minnesota/Montana); Military stationed in ND | 548-day rule |
Leaving North Dakota
North Dakota has no public reputation as an aggressive residency-exit auditor: it does not appear on the practitioner lists (alongside New York, California, New Jersey, Connecticut, Maryland, Minnesota) of states known for chasing departing high earners. Its own top rate of 2.50% gives the state little revenue incentive to fight a departure the way a 9%-13% top-rate state would. The 210-day threshold, which is more generous than the 183-day norm, also makes it harder for the state to catch someone in a statutory-residency net on a close call.
Trailing Income
North Dakota does not have a convenience-of-the-employer rule and does not publish guidance on taxing deferred compensation or stock options after a resident leaves; ordinary federal sourcing rules apply, meaning W-2 wages for work physically performed after departure generally are not North Dakota-source income once residency ends.
Part-Year Filing
Part-year residents file Form ND-1 with Schedule ND-1NR, which apportions income between the resident and nonresident portions of the year. There is no separate 'final year' form.
Enforcement Methods
Common Exit Mistakes
Establishing New York Residency
| Action | Agency | Deadline |
|---|---|---|
| Exchange out-of-state driver license for a New York license | DMV | within 30 days of becoming a resident |
| Register any vehicle kept in New York | DMV | within 30 days |
| Register to vote | New York State Board of Elections | must be a resident of the county for at least 30 days before Election Day; online registration deadline is set 10+ days before each election |
Declaration of Domicile
New York has no formal declaration-of-domicile filing comparable to Florida's county-level process. Domicile is established purely through conduct: home purchase or lease, DMV registration, voter registration, and the pattern of time actually spent, all assessed later under the same five-factor test used to challenge an exit.
Homestead
New York's STAR (School Tax Relief) program reduces school property tax on an owner-occupied primary residence. It is not an asset-protection homestead in the Florida sense, but it functions as strong domicile evidence because enrollment requires attesting the property is the owner's primary residence. The cross-check risk runs both ways: claiming STAR on a New York home while filing a nonresident return elsewhere invites Tax Department scrutiny, and applying for STAR on a newly acquired New York home is a data point supporting a claim of New York domicile.
Voter Registration
Register online, by mail, or in person at a county Board of Elections or the DMV at least 10 days before an election; New York requires county residency of at least 30 days before Election Day. https://elections.ny.gov/register-vote
Vehicle Registration Deadline
30 days
New Resident Tax Traps
A new full-year resident is taxed on worldwide income starting the date New York residency begins; a mid-year move is handled on Form IT-203 by allocating income to the resident and nonresident periods. Anyone moving into the five boroughs should also plan for the added NYC resident income tax, which applies to domiciliaries and statutory residents of the city, not just the state.
What Changes on Tax
North Dakota Top Rate
2.50%
New York Top Rate
10.9% (state); NYC residents add up to 3.876% city tax
Moving from North Dakota to New York raises the top marginal income tax rate from about 2.5% to about 10.9%, an increase of roughly 8.4 percentage points.
Withholding Reciprocity
North Dakota and New York do not have a wage-withholding reciprocity agreement with each other, so this move follows ordinary source-state and resident-state filing rules rather than a reciprocity exception.
Community Property Transition
North Dakota and New York both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
North Dakota
Capital gains: Taxed as income with a partial break: North Dakota allows a 40% exclusion for net long-term capital gains (only 60% of the gain is taxed at ordinary rates), plus a separate exclusion for qualifying gains on the sale of an interest in a North Dakota business. Short-term gains get no exclusion and are taxed as ordinary income.
Estate or inheritance tax: None currently collected. North Dakota's estate tax statute is still on the books but has been inoperative since it was pegged to the federal state death tax credit, which Congress phased out; no estate tax has been paid to North Dakota for deaths after January 1, 2005. The inheritance tax was repealed outright in 1927. No gift tax either.
Property tax: Average effective rate is about 0.99% of home value, close to the national median. The 2025 legislature (HB 1176) raised the Primary Residence Credit from $500 to a maximum $1,600 per year, which the state says eliminated property tax entirely for roughly 50,000 owner-occupied households.
Sales tax: 5% state rate; cities and counties can add local sales tax up to 3%, producing a statewide average combined rate of roughly 6.1%.
New York
Capital gains: No preferential rate. Capital gains are taxed as ordinary income at the same graduated brackets, so a New York City resident in the top brackets can face a combined state and city rate approaching 14.8% on gains before federal tax.
Estate or inheritance tax: New York has an estate tax but no inheritance tax. The 2026 basic exclusion amount is $7,350,000. New York uses a cliff: once a taxable estate exceeds about 105% of the exclusion ($7,717,500 in 2026), the exclusion disappears entirely and the full estate value is taxed, not just the excess.
Property tax: Effective rates vary enormously by locality, from under 1% in parts of New York City (where assessment caps suppress bills) to over 2% in many upstate counties. The STAR program reduces school-tax liability on an owner-occupied primary residence and is one of the first places auditors look when a taxpayer claims nonresident status while still benefiting from it.
Sales tax: State rate is 4%, and combined state-plus-local rates average around 8.5% statewide; New York City's combined rate is 8.875%.
Who This Move Applies To
Travel Nurses
In North Dakota
North Dakota's Bakken-region hospitals (Williston, Minot, Dickinson) are a real travel-nurse market, but the state has no published tax-home-specific guidance beyond the general 210-day/domicile rules. A nurse claiming North Dakota as a tax home while working assignment after assignment in other states faces the same general IRS tax-home scrutiny (Publication 463) that applies nationally; North Dakota itself has no special safe harbor for nurses.
In New York
New York applies its statutory residency test the same way to a travel nurse as to anyone else: a nurse on assignment who is not domiciled in New York but keeps a New York abode for substantially all the year and works more than 183 days in the state becomes a statutory resident taxed on worldwide income. The more common New York exposure runs the other direction, when a nurse claims a Florida or Texas tax home but the facts show the real permanent place of abode is the New York apartment they actually live in during assignments; auditors look at lease length, utility bills in the nurse's name, and whether the claimed home state was ever actually occupied.
Professional Athletes
In North Dakota
North Dakota has no major professional sports franchises, so it does not run a state 'jock tax' apportionment regime of its own. Athletes domiciled in North Dakota (a small number, given the state's size) owe North Dakota tax on their worldwide income subject to credits for tax paid to other states on away-game duty days, but no team is based in-state to generate reciprocal enforcement interest.
In New York
New York originated the modern jock tax, and both the state and New York City tax nonresident athletes on a duty-days basis: New York-source income equals total compensation multiplied by the ratio of duty days spent in New York (games, practices, mandatory appearances, and required travel) to total duty days for the season. New York City separately taxes nonresident athlete earnings at up to 3.876%. This applies to visiting players at Yankee Stadium, Citi Field, Madison Square Garden, and Barclays Center, as well as to the home-team rosters of the Yankees, Mets, Knicks, Nets, Rangers, Islanders, Bills, Giants, and Jets.
Snowbirds, Long Visitors, and RVers
In North Dakota
The generous 210-day threshold is North Dakota's most distinctive feature for long visitors: someone who keeps a North Dakota home and spends up to 210 days in-state per year (nearly seven months) can still avoid North Dakota statutory residency, a materially longer runway than the 183-day states nearby (Minnesota) or in the Northeast.
In New York
The classic New York snowbird risk is keeping a New York co-op or house while wintering in Florida. Under the post-2022 guidelines, an abode used for more than 10 months of the year can satisfy 'substantially all of the taxable year,' and Obus and its Appellate Division reversal show that even a vacation home used only two or three weeks a year can be argued either way depending on whether the taxpayer has genuine, continuous access and uses it as a residence rather than merely maintaining it. Combine that abode with more than 183 days physically in New York across the year, counting any part of a day, and statutory residency attaches regardless of where the person considers home.
Remote Workers
In North Dakota
North Dakota has no convenience-of-the-employer rule. A remote worker who moves to North Dakota and works for an out-of-state employer is taxed by North Dakota as a resident on all income; the risk sits on the origin-state side if that state (e.g., a convenience-rule state like New York) still claims to source the wages there.
In New York
New York's convenience of the employer rule is the single biggest trap for remote workers with a New York-based employer. If a nonresident employee works from home in another state for their own convenience rather than the employer's necessity, New York treats those days as New York workdays and taxes the income, frequently creating double taxation with the employee's home state. The Tax Appeals Tribunal reaffirmed the rule again in Matter of Zelinsky (2025); the only real escape is documenting a bona fide employer necessity, such as the employer having no New York office to work from.
Military
In North Dakota
The 210-day substantial-presence test does not apply to U.S. military personnel who maintain a domicile elsewhere while stationed in North Dakota under orders, consistent with the federal Servicemembers Civil Relief Act. North Dakota also follows the Military Spouses Residency Relief Act for accompanying spouses.
In New York
New York generally follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act: a servicemember stationed in New York on orders does not become a New York domiciliary solely because of the duty station, and military pay is exempt from New York tax for a nonresident servicemember stationed there. A servicemember who was domiciled in New York before enlisting remains a New York domiciliary unless they affirmatively change domicile.
Airline Crew
In North Dakota
North Dakota has small commercial airports (Fargo, Bismarck, Grand Forks, Minot) but is not a hub base for major airline crews. Federal law (49 U.S.C. § 40116) still governs: crew wages are taxable only by the crew member's state of residence and, in limited cases, a state where more than 50% of pay is earned, so North Dakota's low top rate makes it an attractive domicile choice for any crew member who does live there.
In New York
Federal law (49 U.S.C. §40116) limits states to taxing air carrier employee compensation only in the employee's state of residence and any state where the employee earns more than 50% of their pay. This protects flight crew based at a New York hub, such as JFK or LaGuardia, who are domiciled elsewhere from having their full income pulled into New York taxation solely because their duty station is there.
Tools for This Move
North Dakota to New York 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.
If I rent apartments in both New York and Florida and go back and forth all year, how could the state ever prove I was in New York more than 183 days?+
New York's audit program is built for exactly this pattern. Auditors reconstruct day counts from cell phone location data, EZ-Pass toll records, credit and debit card statements, and even medical or veterinary appointments, then compare that reconstruction against your own return. Because any part of a calendar day in New York counts as a full day under 20 NYCRR 105.20, a single afternoon meeting can move the count. The burden of proof is on you, not the state, so the absence of your own contemporaneous records is itself a disadvantage in an audit.
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.
Does keeping an empty apartment in New York count against me if I've moved to Florida?+
It can, but it isn't automatic. Under Matter of Gaied, the Court of Appeals held that merely owning or holding the keys to a New York dwelling isn't enough to make it a permanent place of abode; there has to be evidence you actually use it as a residence. An apartment sitting genuinely empty and unused cuts against a permanent-place-of-abode finding. An apartment you or your family still stay in, even occasionally, is a much harder sell as abandoned.
How does the North Dakota Primary Residence Credit work, and does it prove residency?+
It's a property-tax credit, up to $1,600 a year, for anyone who owns and occupies a North Dakota home as a primary residence, applied for annually between January 1 and April 1 at tax.nd.gov/prc. Because it requires the home to be your primary residence, an approved application is useful supporting evidence of domicile, similar to how a homestead exemption functions in other states, though it is not a formal domicile declaration.
Can I still visit my parents in New York after I claim residency somewhere else without it hurting my case?+
Visiting itself isn't the problem; day counting is. Every day you spend any part of in New York, including a day trip to see your parents, counts toward the 183-day statutory residency threshold if you also maintain a New York abode for substantially all the year. Occasional visits without a New York home available to you are lower risk. The combination of frequent visits and a place to stay, like a childhood bedroom you still use, is what auditors look for.
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.
My employer won't update my payroll state after I moved out of New York. Am I stuck paying New York tax?+
Withholding address alone doesn't establish tax residency, but it does create a paper trail that contradicts your claimed move and can trigger a notice. More importantly, if you continue working remotely for a New York-based employer, New York's convenience of the employer rule can independently tax those wages as New York-source income unless the remote arrangement is a bona fide necessity of the employer, not just your own preference. Fixing the payroll address doesn't fix the convenience rule exposure; those are two separate problems.
Does North Dakota tax my Social Security or my pension after I retire there?+
Social Security is 100% exempt from North Dakota income tax with no income limit. Pensions and 401(k)/IRA withdrawals do not get a similar broad exclusion and are taxed as ordinary income, but North Dakota's top rate is only 2.50%, so the total bill is still low relative to most states that tax retirement income.
How does New York's convenience of the employer rule actually work for remote workers?+
If you're a nonresident who works from home for a New York-based employer, New York treats your home-office days as New York workdays, and taxes that income, unless you can show the remote work was a necessity for the employer rather than your own convenience. The Tax Appeals Tribunal reaffirmed this again in Matter of Zelinsky in 2025. The practical effect is that many remote employees of New York companies owe New York tax on nearly all of their income even though they never set foot in the state, which can also create double taxation with their home state.
Is North Dakota an aggressive state to leave, tax-wise?+
No. North Dakota does not appear in the standard practitioner lists of aggressive exit-audit states (New York, California, New Jersey, Connecticut, Maryland, Minnesota). With a 2.50% top rate, the state has little revenue at stake in a close residency call, and no published cases or defense-cost figures exist for North Dakota residency disputes the way they do for the higher-tax states.
Is it true a New York residency case once turned on where a guy's dog lived?+
Yes. In Matter of Blatt, a CEO who relocated from New York City to Dallas for a new job won his residency case largely because he finally moved his elderly rescue dog to Texas, which the administrative law judge treated as the clearest evidence of genuine intent to relocate. It outweighed the Manhattan apartment he still owned and the boat he kept in the Hamptons, and it landed months before he got a Texas driver's license or registered to vote there. It's a real illustration of how New York's domicile test looks past paperwork to small, honest signals of where someone actually built their life.
