New Hampshire Residency: A No-Tax State After the I&D Repeal

New Hampshire is now a full no-tax state. It has never taxed wages, and its old Interest & Dividends (I&D) tax, the last piece of income the state reached, has been repealed after a multi-year phase-down. That means salary, investment income, and retirement distributions are all untaxed at the state level. The catch is the one every no-tax state shares: New Hampshire won't audit your residency, but the high-tax state you left almost certainly will.

Why New Hampshire is now a top no-tax destination

New Hampshire has always had the "Live Free or Die" reputation, and for income it was mostly earned, the state never imposed a broad wage tax. What kept it off the clean-zero list was the I&D tax, a narrow levy on interest and dividend income above a small exemption. That tax has now been phased out and repealed, putting New Hampshire firmly alongside Florida, Texas, Tennessee, and Nevada as a state that taxes no personal income.

• 0% tax on wages and salary, New Hampshire has never taxed earned income.
• 0% tax on interest and dividends, the I&D tax was phased down and is no longer imposed.
• 0% tax on retirement income, pensions, 401(k) and IRA withdrawals, and Social Security are untaxed at the state level.
• No state sales tax, New Hampshire is one of the few states with neither an income tax nor a general sales tax.
• No state estate or inheritance tax, the federal estate tax still applies above the federal exemption.
• Higher property taxes, the state leans heavily on local property taxes instead, so factor that into your overall cost picture.

Watch the business taxes if you're self-employed

There is one nuance worth flagging before you assume "zero means zero" for every dollar. New Hampshire does levy taxes at the business level, primarily the Business Profits Tax and the Business Enterprise Tax. These are not personal income taxes, but if you operate a sole proprietorship, single-member LLC, or partnership with meaningful New Hampshire activity, your business income can be reached through them.

For most relocating employees, retirees, and investors, this is irrelevant, your wages, dividends, and distributions are simply untaxed. But if you're a founder or self-employed professional moving your operations to New Hampshire, talk to a New Hampshire accountant about how the business taxes apply before you treat the state as a total tax-free zone.

How to establish New Hampshire residency

New Hampshire has no residency "application" and no formal domicile" class="prose-tax-glossary-link" title="Glossary: Declaration of Domicile">declaration of domicile to file with a county clerk the way Florida offers. You establish domicile the way you do in most no-tax states: by combining clear intent with consistent action. Move your actual life, not just your mailing address.

• New Hampshire driver's license at your NH address, and surrender your old-state license.
• New Hampshire voter registration, register and actually vote there.
• New Hampshire vehicle registration and insurance tied to the NH address.
• An NH home as your primary residence, owned or leased, and genuinely lived in.
• New Hampshire banking as your primary financial relationship.
• Local professionals, primary physician, dentist, accountant, attorney based in New Hampshire.
• Updated estate documents, will and trusts revised to recite New Hampshire domicile.
• An NH mailing address on every financial account, brokerage statement, and tax form.

Where your spouse and minor children live, where your most expensive home is, and where you keep sentimental and valuable possessions all carry heavy weight in a domicile contest. The more of these that point to New Hampshire, the stronger your position.

The Massachusetts problem: don't trade NH days for MA wages

New Hampshire's most common relocation story is someone fleeing Massachusetts, and that's exactly where the trap lies. Massachusetts uses a 183-day statutory-residency rule layered on top of domicile: if you keep a permanent place of abode in Massachusetts and spend more than 183 days there, you can be taxed as a full-year Massachusetts resident even after genuinely moving to New Hampshire.

Separately, wages earned for work physically performed in Massachusetts remain Massachusetts-source income and are taxable there even for a true New Hampshire resident. Living in tax-free New Hampshire while commuting across the border to a Massachusetts office does not make your Massachusetts paycheck tax-free, only the days you work from your New Hampshire home shift out of the Massachusetts net. Track where you physically work, not just where you sleep.

The audit comes from your old state, not New Hampshire

Because New Hampshire imposes no income tax, it has no incentive to question your residency. Your former high-tax state does. States like New York, California, and Massachusetts run dedicated residency-departure audit programs aimed squarely at people who claim to have moved away. The two questions they ask are always the same: did you truly change your domicile, and did you spend too many days back in the old state?

Expect a residency audit roughly one to three years after you file your first part-year or nonresident return. The auditor will request cell-tower location data, credit-card and bank statements, toll and E-ZPass records, frequent-flyer history, and social-media activity, then build their own reconstruction of where you spent each day. If their version of your year is better documented than yours, theirs wins.

Track it from day one

Tax Days is built for exactly this playbook. Log your New Hampshire days, your old-state days, and any other states you pass through. The app projects you against each state's exact threshold using the same logic as our 183-day calculator, sends a notification when you're approaching a limit, and exports an audit-ready day log on demand, so when the Massachusetts or New York departure audit arrives, your records are already in order.
