Moving from New Hampshire to Missouri: Residency, Taxes, and What to Prove
New Hampshire's 0% top income tax rate becomes 4.70% in Missouri. 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. Missouri's statutory residency test uses a 183-day threshold.
| Factor | New Hampshire | Missouri |
|---|---|---|
| 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. | Missouri's residency test is set directly by statute, Mo. Rev. Stat. §143.101. A resident individual is either (1) a person domiciled in Missouri, unless they maintain no permanent Missouri residence, do maintain a permanent residence elsewhere, and spend no more than 30 days in Missouri during the tax year, or (2) a person not domiciled in Missouri who nonetheless maintains a permanent place of residence in Missouri and spends more than 183 days of the tax year in the state. This creates two independent paths into Missouri residency: domicile (with a narrow 30-day safe harbor for domiciliaries who've genuinely relocated), and a true statutory residency test for non-domiciliaries who keep a Missouri home and cross 183 days. |
| 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. | Missouri weighs the standard facts-and-circumstances domicile factors: where the taxpayer's permanent home is, driver's license and vehicle registration, voter registration, location of family and employment, and bank and financial ties. A Missouri domiciliary who wants to be treated as a nonresident under the statute's carve-out must both maintain no permanent Missouri residence and keep a permanent residence elsewhere, and spend 30 days or fewer in Missouri for the entire year, which is a materially tighter bar than most states' domicile exit tests. |
| Day Count Threshold | No fixed threshold | 183 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. | Missouri's statute does not define whether a partial day counts toward the 183-day count for non-domiciliaries who maintain a Missouri residence; the Department of Revenue has not published a bright-line partial-day rule comparable to New York's or California's any-part-of-a-day standard, so this is generally treated as a facts-and-circumstances presence question rather than a strict any-part-of-day trigger. |
| Presumptions | None published | The 30-day threshold functions as Missouri's exit safe harbor for domiciliaries: a Missouri domiciliary who maintains no permanent Missouri residence, does maintain one elsewhere, and spends 30 days or fewer in Missouri for the full year is treated as a nonresident despite retaining Missouri domicile. |
| Safe Harbors | None published | 30-day domiciliary safe harbor |
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 Missouri Residency
| Action | Agency | Deadline |
|---|---|---|
| Title and register vehicles in Missouri | Missouri Department of Revenue, Motor Vehicle Bureau | within 30 days of becoming a Missouri resident |
| Obtain a Missouri driver's license | Missouri Department of Revenue | within 30 days of establishing residency |
| Register to vote | Missouri Secretary of State | postmarked by the 4th Wednesday before an election |
| File a Property Tax Credit claim if income-eligible | Missouri Department of Revenue | with the annual return, generally by April 15 |
Declaration of Domicile
Missouri has no formal declaration-of-domicile filing comparable to Florida's county-recorded declaration. Missouri domicile is established through conduct: home purchase or lease, driver's license, vehicle titling, voter registration, and the pattern of actual presence, weighed against the statute's 30-day and 183-day thresholds depending on which side of the domicile question the taxpayer sits on.
Homestead
Missouri's Property Tax Credit ("circuit breaker") is income-capped and limited to homeowners and renters who are seniors (65+) or 100% disabled; it is not a general homestead exemption available to all homeowners the way Florida's or Texas's are. It reimburses a portion of real estate taxes or rent paid, up to $1,100 for homeowners and $750 for renters, and is claimed annually rather than filed once as a standing declaration.
Voter Registration
Your voter registration form must be postmarked by the 4th Wednesday before the election. Register online, by mail, or in person through the Missouri Secretary of State. https://www.sos.mo.gov/elections/goVoteMissouri/register
Vehicle Registration Deadline
30 days
New Resident Tax Traps
Missouri taxes worldwide income from the date Missouri residency begins, reported on the full-year Form MO-1040 or as a part-year filer using Form MO-NRI to allocate income. New residents moving from a no-tax state should note Missouri's deduction for federal income tax paid is a genuine offset most other states don't offer, but it phases out at higher income and does not eliminate the need to plan for both Missouri income tax and the state's above-average combined sales tax in the St. Louis and Kansas City metros.
What Changes on Tax
New Hampshire Top Rate
0%
Missouri Top Rate
4.70%
Moving from New Hampshire to Missouri raises the top marginal income tax rate from about 0% to about 4.7%, an increase of roughly 4.7 percentage points.
Withholding Reciprocity
New Hampshire and Missouri 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 and Missouri both use common law, equitable-distribution marital property rules, so no community property transition applies to this move.
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.
Missouri
Capital gains: Missouri has no separate capital gains rate; gains are included in Missouri adjusted gross income and taxed at the same graduated rates as ordinary income. Missouri does allow a partial subtraction for certain capital gains reinvested through Missouri's income-tax deduction for the sale of low-income housing tax credits and some qualified small-business stock gains, which is narrower than a general exclusion.
Estate or inheritance tax: None. Missouri has no estate tax and no inheritance tax; only the federal estate tax can reach a Missouri decedent's estate.
Property tax: Effective property tax rate on owner-occupied housing runs about 0.89%, below the national average. Missouri does not use a Florida-style homestead exemption; instead it runs the Property Tax Credit ("circuit breaker"), an income-capped rebate of up to $1,100 for qualifying senior or disabled homeowners, and up to $750 for qualifying renters.
Sales tax: State rate is 4.225%, with a statewide average combined rate (state plus local) of about 8.44%, since Missouri allows extensive city, county, and special-district sales tax layering, particularly in the St. Louis and Kansas City metro areas.
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 Missouri
Missouri has no statutory carve-out for travel nurses distinct from its general residency test; the federal tax-home question under IRS Publication 463 governs stipend treatment, and Missouri residency then follows the statutory domicile/183-day framework like any other taxpayer. Missouri's major hospital systems in St. Louis, Kansas City, and Springfield draw a steady stream of travel nursing assignments, and a nurse who claims an out-of-state tax home while actually renting and living in Missouri most of the year risks the same tax-home disallowance pattern documented nationally on travel-nurse forums, which would also expose them to Missouri's statutory 183-day resident test if they maintain a Missouri residence.
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 Missouri
Missouri is home to the Chiefs (whose stadium sits in Missouri just across the state line from Kansas), Royals, Cardinals, and Blues. Missouri applies duty-day apportionment to nonresident professional athletes' income earned from games and team activities in Missouri, consistent with how most income-tax states administer the jock tax, and Missouri-domiciled players on these teams owe Missouri tax on their full income before credits for tax paid to other states where they play road games.
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 Missouri
A Missouri snowbird who is Missouri-domiciled and winters in Florida or Arizona only escapes Missouri tax as a nonresident if they maintain no permanent Missouri residence, keep a permanent residence in the destination state, and spend 30 days or fewer in Missouri for the entire year, which is a much tighter safe harbor than most states offer. A non-domiciled owner of a Missouri vacation or second home faces the opposite risk: maintaining a permanent Missouri residence and crossing 183 days in the state during the year makes them a Missouri statutory resident regardless of where they consider their true domicile.
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 Missouri
Missouri has no convenience-of-the-employer rule, so a genuine Missouri resident working remotely for an out-of-state employer is taxed as a Missouri resident regardless of employer location, and a nonresident working remotely for a Missouri employer generally is not pulled into Missouri tax solely because the employer is headquartered there. The recurring Missouri-specific version of this is Kansas City and St. Louis metro commuters whose employer sits on the other side of a state line; because Missouri applies its statutory 183-day and permanent-residence test rather than a convenience rule, actual physical work location and Missouri presence both matter for anyone with ties on both sides.
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 Missouri
Missouri follows the federal Servicemembers Civil Relief Act and Military Spouses Residency Relief Act. A servicemember whose home of record is Missouri remains a Missouri domiciliary and taxpayer regardless of duty station, and Missouri does not tax a nonresident servicemember's military pay solely because they are stationed in Missouri under orders. Fort Leonard Wood and Whiteman Air Force Base are the state's major installations, and a nonmilitary spouse residing in Missouri solely due to military orders can elect the servicemember's state of legal residence under MSRRA.
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 Missouri
Federal law (49 U.S.C. §40116) limits any state's ability to tax an air carrier employee's pay to the employee's state of residence and any state where more than 50% of pay is earned. Kansas City International and St. Louis Lambert are both significant airports, and Southwest and other carriers maintain crew presence in the Kansas City metro; crew based there who are domiciled elsewhere are protected by the federal carve-out from full Missouri taxation solely because Missouri is their duty station.
Tools for This Move
New Hampshire to Missouri 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.
How many days can I spend in Missouri before I owe Missouri tax as a resident?+
It depends on whether you're Missouri-domiciled or not. A Missouri domiciliary only escapes Missouri residency by maintaining no permanent Missouri home, keeping a permanent home elsewhere, and spending 30 days or fewer in Missouri for the whole year, a tight safe harbor. Someone who is not Missouri-domiciled but keeps a permanent Missouri residence becomes a Missouri statutory resident if they spend more than 183 days in the state during the year.
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.
I moved from Kansas City, Missouri to the Kansas side of the metro but I still cross the state line to visit family and shop constantly. Am I still a Missouri resident?+
Not automatically, but you need to actually meet Missouri's 30-day safe harbor if you're still Missouri-domiciled: no permanent Missouri residence maintained, a real permanent residence on the Kansas side, and 30 days or fewer physically in Missouri for the full year. Frequent short visits to family or for shopping count toward that 30-day total, so a Kansas City metro mover who crosses the state line often should track those days carefully.
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.
What form do I file if I lived in Missouri for only part of the year?+
Part-year residents and nonresidents file Form MO-1040 together with Form MO-NRI, the Nonresident/Part-Year Resident Income Percentage schedule, which calculates what share of your income is taxable by Missouri based on the ratio of Missouri-source income to total income.
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.
Does Missouri tax Social Security benefits?+
No, Missouri exempts Social Security and Social Security Disability benefits from state income tax for most filers, and separately provides a public pension exemption and a private pension deduction that phases out at higher income.
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 Missouri an aggressive state for residency audits?+
No, Missouri is not on the short list of states practitioners and taxpayer forums consistently flag as aggressive on residency, a list dominated by New York, California, New Jersey, Connecticut, Maryland, and Minnesota. That said, Missouri's statutory 183-day test for non-domiciliaries who keep a Missouri residence is a real, enforceable trigger, unlike states that rely purely on subjective domicile factors.
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.
What is Missouri's Property Tax Credit and do I qualify?+
It's Missouri's "circuit breaker" program, an income-capped rebate of up to $1,100 for qualifying senior (65+) or disabled homeowners and up to $750 for qualifying renters, based on real estate taxes or rent paid. It is not a general homestead exemption available to every homeowner; eligibility is limited by age or disability status and household income.
