Moving from New York to New Hampshire: Residency, Taxes, and What to Prove
New York scrutinizes departures closely, so this move is as much an exit-documentation project as a tax question: the top income tax rate drops from 10.9% (state); NYC residents add up to 3.876% city tax to 0%.
Residency Tests Side by Side
New York's statutory residency test uses a 183-day threshold. New Hampshire does not use a simple day-count threshold; it applies a facts-and-circumstances test instead.
| Factor | New York | New Hampshire |
|---|---|---|
| Statutory Residency Test | 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. | New Hampshire has no day-count statutory residency test for income tax purposes, because it has no individual income tax to trigger one. 'Resident or inhabitant' is instead defined for general legal purposes (voting, jury duty, in-state tuition, and similar) under RSA 21:6 and RSA 21:6-a: a person domiciled or having a place of abode in New Hampshire whose actions demonstrate a current intent to make that place their principal place of physical presence to the exclusion of all others. |
| Domicile Test | 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. | Under RSA 21:6-a, 'residence or residency shall mean a person's place of abode or domicile... designated by a person as his or her principal place of physical presence to the exclusion of all others,' and that status 'shall not be interrupted or lost by a temporary absence... if there is an intent to return.' RSA 21:6 adds that the person must have, 'through all of his or her actions, demonstrated a current intent' to treat that place of abode as their principal residence, an actions-based test rather than a pure declaration of intent. |
| Day Count Threshold | 183 days | No fixed threshold |
| Any Part of a Day Rule | 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. | Not applicable. New Hampshire runs no day-count residency test of its own for tax purposes; day counts only matter when a former New Hampshire resident is being evaluated under another state's own statutory-residency rule. |
| Presumptions | 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. | None published |
| Safe Harbors | 548-day rule | None published |
Leaving New York
New York is consistently named by practitioners as one of the most aggressive exit-audit states in the country, alongside California. High earners whose income drops sharply the year they claim to have left, people with day counts close to the 183-day line, and anyone who keeps a New York home after claiming a new domicile are the standard audit triggers. Per Hodgson Russ's published nonresident audit guide, the process is document-intensive and commonly runs 12 to 24 months.
Trailing Income
New York keeps taxing former residents through the convenience of the employer rule: a nonresident who teleworks for a New York-based employer is treated as working in New York, and therefore taxed on that income, unless the remote arrangement is a bona fide necessity of the employer rather than the employee's own convenience. Deferred compensation and stock options tied to services performed while a New York resident or while working in New York remain New York-source income even after the person moves away.
Part-Year Filing
Form IT-203, Nonresident and Part-Year Resident Income Tax Return, is used both for part-year residents leaving New York and for full-year nonresidents with New York-source income. The filer computes tax as if a full-year resident, then apportions it by the share of income allocable to the resident period plus any New York-source income earned during the nonresident period.
Enforcement Methods
Common Exit Mistakes
Establishing New Hampshire Residency
| Action | Agency | Deadline |
|---|---|---|
| Get a New Hampshire driver's license | NH Division of Motor Vehicles (DMV) | within 60 days of establishing residency |
| Register vehicles | NH DMV / municipal clerk | within 60 days of establishing residency (NH RSA 261:45 and 263:35) |
| Register to vote (same-day registration available) | NH Secretary of State / town or city clerk | no advance deadline; you can register and vote on Election Day itself with proof of domicile |
Declaration of Domicile
New Hampshire has no formal declaration-of-domicile filing. Domicile/residence under RSA 21:6-a is established through conduct and documentation: a New Hampshire driver's license, vehicle registration, and voter registration all showing your New Hampshire address, each of which is explicitly accepted as domicile proof when you register to vote.
Homestead
New Hampshire has no broad homestead property-tax exemption comparable to Florida's or Maine's. It does provide the narrowly targeted Low & Moderate Income Homeowners Property Tax Relief program (RSA 198:57), which refunds a portion of the State Education Property Tax for owner-occupants with AGI at or below roughly $20,000 (single) or $40,000 (married/head of household), and separate age-based elderly exemptions set by individual towns. Neither functions as general domicile evidence the way a Florida or North Dakota homestead credit does.
Voter Registration
New Hampshire allows same-day registration: register in advance at your town or city clerk's office, or simply show up at the polls on Election Day with proof of identity, age, citizenship, and domicile (a NH driver's license, non-driver photo ID, or vehicle registration showing your domicile address all qualify). https://www.doj.nh.gov/bureaus/election-law-unit/establishing-domicileresidence-new-hampshire

New Resident Tax Traps
There is effectively no individual income-tax trap on the way in, since New Hampshire taxes none of it. The real trap is the opposite of most states: New Hampshire's high property tax (roughly 2.1% average effective rate, the highest in New England) can offset a large share of the income-tax savings that drew someone here from Massachusetts, and anyone who continues working for a Massachusetts employer needs to separately confirm Massachusetts is no longer sourcing their wages.
What Changes on Tax
New York Top Rate
10.9% (state); NYC residents add up to 3.876% city tax
New Hampshire Top Rate
0%
Moving from New York to New Hampshire drops the top marginal income tax rate from about 10.9% to about 0%, a reduction of roughly 10.9 percentage points.
Withholding Reciprocity
New York and New Hampshire 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
New York and New Hampshire both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
Beyond Income Tax
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%.
New Hampshire
Capital gains: Not taxed at the individual level. With the Interest and Dividends Tax gone, New Hampshire has no mechanism left to tax an individual's capital gains, interest, or dividend income; only the state's business taxes (Business Profits Tax, Business Enterprise Tax) reach investment-type income earned through a business entity.
Estate or inheritance tax: None. New Hampshire has no estate tax and no inheritance tax; only the federal estate tax can apply to a New Hampshire domiciliary's estate above the federal exemption.
Property tax: New Hampshire funds most local and school services through property tax in the absence of income or sales tax, producing the highest average effective property tax rate in New England, commonly cited around 2.1% of home value. There is no broad homestead exemption; the state instead runs a targeted Low & Moderate Income Homeowners Property Tax Relief program (RSA 198:57) for the State Education Property Tax portion only, capped at roughly $20,000 AGI (single) or $40,000 (married/head of household).
Sales tax: None. New Hampshire has no general state or local sales tax, a major draw for cross-border shoppers from Massachusetts and Maine.
Who This Move Applies To
Travel 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.
In New Hampshire
New Hampshire has no state income tax to complicate a travel nurse's tax-home analysis, which makes it an attractive tax-home state to claim, similar to Florida or Texas, provided the nurse genuinely maintains and returns to a New Hampshire home between assignments under the general IRS tax-home rules (Publication 463). New Hampshire itself publishes no nurse-specific guidance because it has no individual filing requirement to trigger one.
Professional Athletes
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.
In New Hampshire
New Hampshire has no major professional sports franchises, so it runs no state jock-tax regime of its own, and because it has no income tax, a New Hampshire-domiciled athlete owes zero state tax on the share of income attributable to New Hampshire duty days, unlike a player based in a state that both taxes and credits.
Snowbirds, Long Visitors, and RVers
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.
In New Hampshire
New Hampshire places no day-count cap on long visitors of its own, since it has no statutory residency test. The exposure runs entirely the other way: someone who claims New Hampshire domicile to escape a high-tax origin state (most commonly Massachusetts) but still spends significant time and keeps a home in that origin state can be taxed there as a statutory resident regardless of the New Hampshire claim.
Remote Workers
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.
In New Hampshire
New Hampshire has no convenience-of-the-employer rule (it has nothing to source, having no income tax). The real friction runs the other direction: a remote worker who moves to New Hampshire but keeps a Massachusetts-based employer needs to confirm Massachusetts is not still asserting Massachusetts-source treatment of the wages under its own COVID-era sourcing rules, which New Hampshire itself challenged (unsuccessfully, at the Supreme Court) on behalf of its residents in 2020-2021.
Military
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.
In New Hampshire
New Hampshire follows the federal SCRA and MSRRA: a service member's home-of-record does not change solely because military orders station them in New Hampshire, and an accompanying spouse can generally elect the service member's domicile state under MSRRA. Because New Hampshire taxes no individual income, choosing it as home-of-record eliminates state income tax on military pay entirely.
Airline Crew
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.
In New Hampshire
New Hampshire has no major hub airport for airline crew, but the federal carve-out (49 U.S.C. § 40116, taxing crew wages only in the state of residence or a state where over 50% of pay is earned) combined with New Hampshire's lack of any income tax makes it, like Florida and Texas, a common domicile choice for crew based at nearby Boston Logan who want to avoid Massachusetts income tax on their wages.
Tools for This Move
New York to New Hampshire FAQ
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.
Does New Hampshire still tax my interest and dividends?+
No. New Hampshire's Interest and Dividends Tax, which had applied a declining rate down to 3% by 2024, was fully repealed for tax periods beginning January 1, 2025, under House Bill 2. New Hampshire now has zero individual income tax of any kind, on wages, dividends, interest, or capital gains.
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.
If I move to New Hampshire but keep working for my Massachusetts employer, will Massachusetts still tax my wages?+
Possibly, depending on how your employer sources the wages and how much you actually work from New Hampshire versus commuting into Massachusetts. New Hampshire itself sued Massachusetts over its pandemic-era rule taxing New Hampshire residents' wages as if earned in Massachusetts; the U.S. Supreme Court declined to hear the case in 2021, so the practical fight over sourcing happens on the Massachusetts side, not in New Hampshire, which has nothing to tax either way.
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.
Do I need to file a New Hampshire tax return once I move here?+
No individual income tax return exists to file. If you own a sole proprietorship, partnership, or other pass-through business with New Hampshire activity, you may still owe the Business Profits Tax (7.5% on business profits) and Business Enterprise Tax, filed on Form NH-1040, but that is a business filing, not a personal residency filing.
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.
How can I prove I actually live in New Hampshire and not just claim it on paper?+
Because New Hampshire has no income tax audit process to satisfy, the proof that matters is whatever your former high-tax state (commonly Massachusetts) demands to disprove its own residency claim: a New Hampshire driver's license and vehicle registration, voter registration under RSA 21:6-a's domicile standard, a day-count log showing more time in New Hampshire than the old state, and evidence the New Hampshire home is your actual principal place of physical presence.
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 New Hampshire property tax really that high if there's no income or sales tax?+
Yes. New Hampshire's average effective property tax rate runs around 2.1%, the highest in New England, because property tax funds most local and school services in the absence of income or sales tax revenue. For a high-value home, that can offset a meaningful share of the income-tax savings that motivated the move, especially for someone leaving a state with a moderate income tax rate.
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.
How long do I have to get a New Hampshire driver's license and register my car after moving here?+
You have 60 days from establishing residency to do both, under RSA 261:45 and RSA 263:35. Most town clerk offices recommend registering the vehicle first and getting the license the same visit, since both can typically be handled together.
