Living in New Hampshire, Working in Massachusetts: The Tax Math Nobody Explains Before You Buy

Here's a scenario I run into all the time: someone working in Massachusetts is eyeing a move across the border to New Hampshire. The pitch sells itself — "New Hampshire has no income tax." Live free or die, keep more of your paycheck, buy more house.

The instinct is right, but the math is more complicated than the bumper sticker, and if you're about to buy a home based on it, you need the real numbers — not the myth. Let me walk you through what actually happens to your taxes when you live in New Hampshire and work in Massachusetts, and why it matters for what you can afford.

Quick disclaimer up front: I'm a mortgage loan officer, not a CPA or tax advisor. What follows is a general explanation to help you plan — for your specific situation, talk to a tax professional. But this is the framework you need to understand before you start house hunting.

The Myth: "No Income Tax in New Hampshire"

The first half is true. As of 2026, New Hampshire has zero state income tax — no tax on wages, and as of January 1, 2025, no tax on interest and dividends either (the old I&D tax was fully repealed). If you live and work in New Hampshire, you genuinely pay no state income tax. That's real.

The catch is the second half, and it's the part the bumper sticker leaves out.

The Reality: Massachusetts Taxes Where You Work, Not Where You Live

Massachusetts taxes income based on where the work physically happens. So if you live in New Hampshire but commute into Massachusetts for your job, Massachusetts still taxes the wages you earn on Massachusetts soil — at 5%, or 9% on income above $1 million thanks to the state's millionaire surtax.

You'd file a Massachusetts non-resident return (Form 1-NR/PY) for that income, and there's no New Hampshire return to offset it because New Hampshire doesn't have an income tax in the first place. You simply pay Massachusetts on your Massachusetts-earned wages.

In plain terms: moving to New Hampshire does not make your Massachusetts paycheck tax-free. If your job is in Boston and you're physically there five days a week, your wage tax situation barely changes by moving north.

Where the Move Actually Saves You (And It Can Be a Lot)

So where's the real benefit? A few places:

Days you work from New Hampshire aren't Massachusetts-taxed. This is the big one in the hybrid-work era. The old COVID rule that taxed New Hampshire remote workers as if they were still in Massachusetts expired back in September 2021. Today it's physical-presence based. So if you're hybrid — say, in the office three days a week and home in New Hampshire two — those New Hampshire work days aren't Massachusetts-source income, and New Hampshire doesn't tax them either. That portion of your income becomes genuinely tax-free.

Your investment income is New Hampshire's, not Massachusetts's. Interest, dividends, and capital gains for a New Hampshire resident aren't taxed by Massachusetts (they're sourced to where you live), and New Hampshire no longer taxes them at all. For someone with meaningful investment or retirement income, that's a real, permanent savings.

A spouse who works in New Hampshire pays no income tax on those wages. If one of you works in Massachusetts and the other works in (or from) New Hampshire, the New Hampshire-working spouse's income escapes Massachusetts entirely — which isn't the case if you both live in Massachusetts.

So the fully-remote worker, the hybrid worker, the investor, and the dual-income couple with one NH-based job all stand to save. The pure five-days-a-week Boston commuter saves the least on income tax.

The Part That Hits Your Mortgage: New Hampshire Property Taxes

Here's what almost nobody weighs properly, and it's the piece that matters most when you're buying a home.

New Hampshire funds its schools and services without an income tax or a sales tax — which means it leans hard on property taxes. New Hampshire has among the highest effective property tax rates in the entire country: roughly 2% of home value per year on average, compared to a little over 1% in Massachusetts.

Put real numbers on it. On a $500,000 home, you're looking at roughly $10,000 a year in property taxes in New Hampshire versus closer to $5,800 in Massachusetts — a difference of around $4,000 a year, or over $350 a month.

And that difference doesn't just cost you at tax time — it directly affects your mortgage. Your property tax is baked into your monthly payment (through escrow) and into the debt-to-income ratio lenders use to qualify you. A higher tax bill means a higher monthly payment, which means you qualify for a somewhat smaller loan for the same monthly budget. Two identical $500,000 homes, one in New Hampshire and one in Massachusetts, can carry meaningfully different monthly payments purely because of the tax line.

So when you're comparing "what can I afford in NH vs MA," you can't just look at sticker price. The New Hampshire home might list for the same or less, but the monthly cost — and the loan you qualify for — swings on that property tax number.

So Does the Move Make Sense?

Often, yes — but for the right reasons, with eyes open. The honest way to think about it:

• If you're fully remote or heavily hybrid, the income-tax savings on your New Hampshire work days are real and can meaningfully offset the higher property tax.
• If you have significant investment or retirement income, New Hampshire's zero tax on that is a durable win.
• If you're a five-day Boston commuter with modest investments, the income-tax savings are thin, and the higher property tax may actually make the total cost of ownership higher than staying in Massachusetts. The move might still be worth it for space, schools, or lifestyle — just don't do it purely for the tax myth.

The point isn't that New Hampshire is a bad move. For plenty of people it's a great one. The point is that "no income tax" is only one line in a much bigger equation, and the property tax line is the one that shows up in your mortgage payment every single month.

Run Your Actual Numbers Before You Fall in Love With a House

This is exactly the kind of decision where a fifteen-minute conversation beats a spreadsheet full of assumptions. Because I'm licensed in both Massachusetts and New Hampshire, I can help you compare real payments on both sides of the border — factoring in the property tax difference, what you'd qualify for, and how your work situation affects the tax picture — so you're making the call on real numbers instead of a bumper sticker.
