Moving from New Hampshire to Arizona: Residency, Taxes, and What to Prove
New Hampshire's 0% top income tax rate becomes 2.5% in Arizona. This move trades a lighter tax environment for a heavier one, so timing income around the transition year matters.
Residency Tests Side by Side
New Hampshire does not use a simple day-count threshold; it applies a facts-and-circumstances test instead. Arizona's statutory residency test uses a 274-day threshold.
| Factor | New Hampshire | Arizona |
|---|---|---|
| Statutory Residency 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. | Arizona Revised Statutes §43-104 defines a resident as anyone domiciled in Arizona, or anyone who is in Arizona for other than a temporary or transitory purpose. The statute also sets a presumption: an individual who spends in aggregate more than nine months (roughly 274 days) of the tax year in Arizona is presumed a resident, rebuttable with evidence the presence was temporary or transitory. |
| Domicile Test | 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. | Arizona applies the common-law domicile test described in ADOR Individual Income Tax Procedure ITP 92-1: physical presence in a place combined with intent to make it your permanent home. Domicile, once established, is presumed to continue until affirmatively changed, and the burden of proving a change falls on the person claiming it. |
| Day Count Threshold | No fixed threshold | 274 days |
| Any Part of a Day Rule | 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. | ADOR guidance under ITP 92-1 counts any day with any physical presence in Arizona toward the aggregate nine-month presumption count, similar in concept to California's approach, though in practice Arizona applies it with less aggressive enforcement than California. |
| Presumptions | None published | ARS §43-104's nine-month (roughly 274-day) presumption of residency, rebuttable by evidence the time in Arizona was temporary or transitory. |
| Safe Harbors | None published | None published |
Leaving New Hampshire
New Hampshire does not audit anyone leaving for individual income-tax purposes, because it has never taxed wages and, since January 2025, no longer taxes interest and dividends either. The only residency-adjacent risk on the way out involves the Low & Moderate Income Homeowners Property Tax Relief program and the state's Business Profits/Business Enterprise Tax obligations for anyone who ran a New Hampshire-based sole proprietorship or pass-through entity, neither of which resembles a personal residency audit.
Trailing Income
New Hampshire does not tax wages, capital gains, deferred compensation, or retirement distributions for individuals, so there is nothing to claw back after departure at the personal level. A former resident's New Hampshire-sourced business income can still be reached through the Business Profits Tax if the business activity continues to have New Hampshire nexus.
Part-Year Filing
Not applicable for individual income tax; New Hampshire has no individual income tax return of any kind for a departing resident to file. Anyone who owned a New Hampshire sole proprietorship or pass-through business may still need to close out Business Profits Tax (Form NH-1040) and Business Enterprise Tax filings.
Enforcement Methods
Common Exit Mistakes
Establishing Arizona Residency
| Action | Agency | Deadline |
|---|---|---|
| Get an Arizona driver's license | Arizona MVD | within 30 days of establishing residency |
| Title and register vehicles in Arizona | Arizona MVD | within 15 days of establishing residency |
| Register to vote | Arizona Secretary of State | 29 days before an election |
Declaration of Domicile
Arizona has no formal declaration-of-domicile filing. Domicile is shown through conduct: purchasing or leasing an Arizona home, obtaining an Arizona driver's license, registering to vote, and opening Arizona bank accounts.
Homestead
Arizona's homestead exemption automatically protects up to $425,200 (as of January 2025, adjusted annually for inflation under ARS §33-1101) of equity in a primary residence from most creditors, with no filing required. Because it's automatic and adjusts every year, it's a weaker domicile-evidence signal than a state requiring an affirmative recording, but ADOR and other agencies can still cross-check ownership records against claimed nonresident status.
Voter Registration
Register at least 29 days before an election. https://azsos.gov/elections/voters/registering-vote
Vehicle Registration Deadline
15 days
New Resident Tax Traps
Arizona taxes a new resident's worldwide income starting the date residency begins, requiring the Form 140PY apportionment for the year of the move. Because Arizona closely conforms to federal adjusted gross income, most federal timing issues around moving (like relocation-related deferred compensation) flow directly onto the Arizona return without separate state-specific adjustment.
What Changes on Tax
New Hampshire Top Rate
0%
Arizona Top Rate
2.5%
Moving from New Hampshire to Arizona raises the top marginal income tax rate from about 0% to about 2.5%, an increase of roughly 2.5 percentage points.
Withholding Reciprocity
New Hampshire and Arizona 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 Hampshire uses common law marital property rules and Arizona is a community property state. Property acquired during marriage after the move may be characterized differently going forward, which matters for estate planning and for basis step-up on a spouse's death.
Beyond Income Tax
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.
Arizona
Capital gains: Taxed as ordinary income at the flat 2.5% rate, but Arizona allows a 25% subtraction on qualifying net long-term capital gains (ARS §43-1022), which brings the effective rate on those gains down to about 1.875%. As of January 1, 2026 the subtraction applies to all qualifying long-term gains, not just assets acquired after 2011. Short-term gains get no subtraction and are taxed at the full 2.5%.
Estate or inheritance tax: None. Arizona has no estate tax and no inheritance tax.
Property tax: Effective rate is among the lowest in the country, roughly 0.45% to 0.56% depending on county, with Maricopa County near the higher end. Arizona offers a Senior Property Valuation Protection option that freezes the assessed value for qualifying low-income seniors 65 and older, rather than a general homestead portability system.
Sales tax: 5.6% state transaction privilege tax base rate, with combined state-and-local rates commonly running 8% to 9% in metro Phoenix and up to about 11.2% in some jurisdictions.
Who This Move Applies To
Travel Nurses
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.
In Arizona
Arizona's Phoenix and Tucson hospital systems make it one of the largest travel nurse markets in the country. A nurse who is actually Arizona-domiciled and takes Arizona contracts is simply an Arizona resident under ordinary rules. A nurse who claims Arizona as a tax home while working travel assignments elsewhere needs a genuine, regularly used Arizona residence with duplicated living expenses, or the stipend portion of their pay risks being reclassified as taxable wages if audited.
Professional Athletes
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.
In Arizona
Arizona is home to the Cardinals, Suns, Diamondbacks, and the Coyotes' successor tenant at Mullett Arena, and MLB's Cactus League spring training in March adds a significant block of extra duty days for every visiting team's roster. Arizona applies standard duty-day allocation to nonresident athlete income, but because the flat rate is only 2.5%, Arizona produces one of the lowest jock-tax burdens of any state that taxes athlete income at all.
Snowbirds, Long Visitors, and RVers
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.
In Arizona
This is Arizona's signature scenario: the state's own nine-month (roughly 274-day) presumption explicitly allows spending a large chunk of the year in Arizona without automatically becoming a resident. Large numbers of California and Midwest retirees winter in the Phoenix and Tucson areas from October through April while keeping their prior-state domicile, but they need to track their total Arizona days against the 274-day threshold and remember their origin state runs its own, separate presumption pointing the other direction.
Remote Workers
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.
In Arizona
Arizona has no convenience-of-employer rule. A nonresident who performs all their work physically outside Arizona for an Arizona-based employer is not Arizona-taxed on those wages. Arizona also has a narrow reciprocal withholding exemption (Form WEC) with California, Indiana, Oregon, and Virginia: residents of those four states working in Arizona can request their Arizona employer withhold no Arizona tax, though the arrangement runs one direction and doesn't create general two-way income tax reciprocity.
Military
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.
In Arizona
Arizona follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. Nonresident military stationed in Arizona under orders don't become Arizona residents from the posting alone, and their military pay isn't Arizona-taxed if domiciled elsewhere. Arizona also fully exempts military retirement pay for its own domiciled veterans.
Airline Crew
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.
In Arizona
American Airlines operates a major hub and crew base at Phoenix Sky Harbor (PHX). Federal law (49 U.S.C. §40116) limits taxation of air carrier employees to their state of residence and any state where they earn more than 50% of pay, which matters directly for Arizona-based crew flying national routes.
Tools for This Move
New Hampshire to Arizona FAQ
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 Arizona use the 183-day rule?+
Not exactly. Arizona's statutory presumption under ARS §43-104 kicks in after more than nine months, roughly 274 days, of aggregate presence in a tax year, not 183 days. Spending fewer than 274 days doesn't automatically make you a nonresident either; Arizona still looks at your domicile and intent.
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.
How many months can I spend in Arizona as a snowbird before I owe Arizona income tax?+
Arizona's own presumption threshold is more than nine months (about 274 days) in the state during the tax year. Under that, you're not automatically presumed an Arizona resident, but your home state's own rules, for example California's nine-month presumption running the other direction, may still treat you as a resident there regardless of your Arizona day count.
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.
Do I have to pay Arizona tax on my California retirement income if I move to Arizona?+
Yes, once you're an Arizona resident, your 401(k), IRA, and pension distributions are taxed at Arizona's flat 2.5% rate regardless of where the money was earned or which state's employer originally sponsored the plan. Only Social Security and Arizona-recognized military retirement are exempt.
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.
What's Arizona's income tax rate?+
A flat 2.5% on all taxable income, with no brackets. It's one of the lowest state income tax rates in the country among states that tax income at all.
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.
Does Arizona tax Social Security?+
No. Arizona fully exempts Social Security benefits from state income tax, regardless of your total income level.
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.
Does Arizona have a capital gains tax?+
Arizona taxes capital gains as ordinary income at the flat 2.5% rate, but allows a 25% subtraction on qualifying long-term gains, which brings the effective rate on those gains down to roughly 1.875%. Short-term gains get no subtraction.
Considering the reverse move?
Arizona to New Hampshire
Moving the other direction is a different fact pattern, not a mirror image: exit risk and establishment mechanics both flip.
