Residency rules, sticky taxes, and first-year steps (2026)
2026.1 Edition · Revised 2026-07-25 · DomusDay Research
The move changes the rate; the record decides whether it sticks. Massachusetts keeps taxing until domicile actually changes — true, fixed and permanent home — the whole fabric of a life, on the facts, and its 183-day statutory test stays live while any Massachusetts abode is maintained. Below: what follows leavers, and the New Hampshire steps that build the record.
Who has to show it: on the party asserting the change of domicile; declarations of intent are examined closely against conduct.
At Massachusetts's top marginal rate (9%), every $100,000 of taxable income is $9,000 of state tax — an illustration at the top bracket, not an effective-rate calculation. Official rate tables are linked below.
The I&D tax was phased down and is repealed for taxable periods beginning after December 31, 2024. With wages and salaries never taxed, no New Hampshire tax now applies to individuals' personal income — and there is no general sales tax either.

Source ↗New Hampshire registers voters at the polling place on election day with proof of identity, age, citizenship, and domicile in the town or ward (RSA 654:7-a) — a same-day, dated record of civic ties that most states close weeks before an election.
Source ↗New Hampshire is the easy half. Massachusetts decides whether the move counts, and it decides on evidence — the two tests below stay live until the record closes them out.

The headline delta: Massachusetts taxes its top bracket at 9% while New Hampshire has no personal income tax. At the top marginal rate — an illustration, not an effective-rate calculation — every $100,000 of taxable income is $9,000 of state tax that stops accruing once Massachusetts residency actually ends. The rules above decide when that is; the day count and the domicile record decide whether it holds up.
The first weeks in New Hampshire matter more than they look: each step below produces a dated document, and dated documents are what answer a Massachusetts examiner years later. Do them early and the record starts on your side of the timeline.
New residents have a maximum of 60 days from the date residency is established to obtain a New Hampshire driver license (RSA 263:35).
Source ↗A person who establishes domicile/residence and owns a vehicle used in New Hampshire registers it within 60 days; the process begins at the town or city clerk's office in the municipality of residence, with the title and proof of residency (RSA 261:45).
Source ↗Registration is a two-part process: the municipal portion at the town or city clerk, then the state transaction. Many clerks act as state agents and complete both parts in one visit.
Source ↗Voter registration runs through the town or city — including registration at the polling place on election day, with proof of identity, age, citizenship, and domicile in the town or ward (RSA 654:7-a).
Source ↗RSA 21:6 defines a resident as a person domiciled or with a place of abode in the state who has, through all of his or her actions, demonstrated a current intent to make that abode the principal place of physical presence to the exclusion of all others — the license, registration, and voter records above are the dated acts that definition looks to.
Source ↗The homestead right arises automatically: $400,000 of the homestead per person is exempt from attachment and sale on execution — $550,000 combined for married couples — under RSA 480:1 as amended effective January 1, 2026. No declaration or application is filed.
Source ↗Towns take the annual inventory of taxable property as of April 1 (RSA 74:1); a purchased home appears in the new town's assessment and property tax records from that date, a dated tie to the municipality.
Source ↗New Hampshire motor vehicle laws do not require auto insurance; drivers instead demonstrate the means to meet financial responsibility requirements after an at-fault accident. Purchased policies start at 25/50/25 liability limits with $1,000 medical payments coverage.
Source ↗There is no New Hampshire return on wages or salaries — the state has never taxed them — and the interest and dividends return ends for taxable periods beginning after December 31, 2024.

No. Wages and salaries have never been taxed, and the interest and dividends tax — the last state tax on individuals' personal income — is repealed for taxable periods beginning after December 31, 2024. There is no general sales tax either.
Not on the Massachusetts wages. Massachusetts taxes nonresidents on Massachusetts-source income, so a New Hampshire resident who works in Massachusetts files a Massachusetts nonresident return on that income. Income from other sources — investment income, out-of-state wages — leaves Massachusetts' reach with residency.
A New Hampshire driver license within 60 days, vehicle registration within 60 days — starting at the town or city clerk — and voter registration, which is available at the polling place on election day. Each produces a dated record; there is no declaration of domicile to file.
