Leaving Massachusetts for New Hampshire: A Financial Relocation Guide for High Earners

You didn’t spend years building a seven-figure career to keep losing a bigger slice of your earnings to Massachusetts state income tax every April.

Yet, that’s exactly what’s happening to a growing number of high earners being hit with the state’s 4% surtax. A high year-end bonus. The RSUs finally vested. The business sale you’d been planning finally closed. Suddenly, somewhere in all that good news sits a line you didn’t expect: Massachusetts’s 4% surtax, stacked on top of its 5% flat rate, kicking in the moment your taxable income clears $1,107,750 in 2026.

Unfortunately, that surtax is often the cost of doing well in a state that taxes success harder than it used to. It’s also exactly why many Massachusetts families have started asking a serious question: what would it actually mean to leave? 

For many, the answer points north, to New Hampshire towns like Keene and Manchester, where the tax code can be appealing to Mass residents looking for a change. While, relocating to New Hampshire can be a smart financial move for high-earning households, it often requires more than a moving truck and a new address. Here are some important factors to know about the process. 

It’s Not Just a Salary Problem

Massachusetts runs on a flat 5% income tax, which sounds simple enough until a high-income year pushes you past the surtax line. In 2026, any taxable income above $1,107,750 will incur an additional 4% surtax on top. Often called the Massachusetts millionaire tax, that 4% brings the combined rate on that portion of income to 9%. 

The surtax doesn’t just apply to wages. It can also apply to capital gains, bonuses, and business income, which means it’s not just a salary problem. A single strong year, whether from a liquidity event, an RSU vest, or a home sale, can trigger it even for households whose regular income sits well below the threshold.

New Hampshire offers a different starting point. There’s no tax on wages, no tax on investment income, and no state capital gains tax at all. For a household earning well into seven figures, that difference isn’t marginal. It can mean tens of thousands of dollars a year staying in your accounts instead of the state’s.

What NH Does and Does Not Tax

Beyond no tax on wages, New Hampshire also has no sales tax, so a car, a renovation, or anything else you buy actually costs the sticker price. There’s also no estate or inheritance tax, which matters for anything you’re planning to leave behind, not just what you earn while you’re here.

That’s the appealing side of the ledger. The other side deserves equal attention: New Hampshire leans harder on property taxes than many other states, with an effective rate of roughly 1.50% on owner-occupied homes. In Keene specifically, that number runs higher still, with a median effective rate closer to 3.31%. 

That’s the real trade-off to model before you move: what you save on income tax against what you’ll pay in property tax on the home you actually buy. For many high earners leaving Massachusetts, the math still favors New Hampshire, but it’s worth running your specific numbers rather than assuming.

The Residency and Domicile Reality

For households considering the move, one detail generally matters most: residency. Buying a home in New Hampshire doesn’t automatically make someone a New Hampshire resident for tax purposes. That distinction often comes down to domicile: where you genuinely intend to make your permanent home, generally demonstrated through your actions rather than an address alone.

Massachusetts may still consider a former resident a taxpayer if enough ties to the state remain, even after purchasing a home in New Hampshire. Establishing NH residency typically involves a combination of factors that can include:

• Time spent in each state, with 183 days often cited as a general benchmark
• Which home is listed as the primary residence on a driver’s license, voter registration, and tax filings
• Where healthcare providers, financial professionals, and other regular ties are based
• Whether the Massachusetts home has been sold, rented, or otherwise meaningfully vacated

A Massachusetts residency audit can review all of this, particularly for households whose income may otherwise be subject to the surtax. Working through this process with a CFP® and an experienced estate attorney can help make sure the details are documented correctly from the start.

Timing the Move Around an Income Event

Not all moves are created equal, and timing is often the difference. Income earned while still domiciled in Massachusetts is generally still subject to Massachusetts tax, including the surtax, even if the move to New Hampshire happens shortly after.

For anyone anticipating a bonus, an RSU vest, or a business sale, that timeline deserves the same attention as the move itself. Establishing residency before the income event, rather than around the same time or after, is typically what allows a household to capture the full benefit of the move. This is one area where planning ahead with a CFP® can prove helpful, since the sequence of events can be as important as the move itself.

Running the Real Numbers Before You Move

The only way to know if a move from Massachusetts to New Hampshire makes sense is to run your own numbers. A general rule of thumb won’t tell you what you need to know.

Let’s use a hypothetical example. Consider a household that earns $2 million in a strong year, maybe from a bonus, a business sale, or vested equity. In Massachusetts, that income is taxed at the standard 5% rate, plus an extra 4% on the portion above $1,107,750. Combined, the state tax bill can run well into six figures. In New Hampshire, that same $2 million could potentially owe no state income tax at all.

Now let’s factor in the trade-off: property tax. A $1.5 million home in Keene, at a median effective rate of 3.31%, comes out to roughly $49,650 a year. That’s a significant cost, but for a household earning well into seven figures, it’s usually still less than what they paid Massachusetts in income tax.

Put simply: the more income involved, the more the math tends to favor New Hampshire. The closer a household sits to the $1,107,750 surtax threshold, the closer that gap gets, which is exactly why this is worth calculating with a professional advisor using real numbers, not assumptions.

Resetting Your Financial Plan for New Hampshire

Many people focus solely on the tax and residency pieces when considering a move like this. However, a relocation can impact nearly every part of a financial plan, not just the state line on a tax return.

For example, when leaving Massachusetts, it’s important to revisit healthcare. Provider networks, insurance coverage, and even Medicare planning can look different in your new zip code. It’s worth confirming continuity of care before the move rather than after. For households moving to Keene, NH, that might mean identifying new specialists closer to the Monadnock Region. For those relocating to Manchester, NH, or another southern New Hampshire relocation, proximity to Boston-based providers may make the transition easier.

Estate documents also deserve a second look. Wills, trusts, and powers of attorney drafted under Massachusetts law generally continue to be valid in New Hampshire, but state-specific nuances, particularly around New Hampshire’s lack of a state estate tax, can create planning opportunities worth revisiting with an attorney.

A few other areas worth addressing as part of the transition:

• Updating beneficiary designations and account registrations to reflect a new address and state of domicile
• Re-evaluating auto and homeowners insurance, since coverage and rates can shift meaningfully between states
• Reviewing investment accounts for any Massachusetts-specific considerations that no longer apply
• Confirming banking and financial accounts reflect the new primary residence

None of this has to happen all at once, but treating the move as a full financial reset, rather than a change of address, tends to serve households well over the long run.

A Relocation and Residency Checklist

Before listing a Massachusetts home, it’s worth having a plan. A general checklist to work from:

• Map any upcoming bonus, equity vest, or business sale against your target move date
• Set up New Hampshire as your legal home base: license, registration, voting
• Keep a running log of days spent in each state during the transition year
• Close out the Massachusetts property, whether that means a sale or a genuine handoff to renters
• Run the property tax numbers on the specific New Hampshire home you’re considering
• Loop in an estate attorney and CFP® to update documents, beneficiaries, and coverage for your new state

Because a Massachusetts residency audit can review each of these details individually, getting the sequence right from the start matters more than fixing it later.
