The Real Math: NH vs MA Tax Savings for Luxury Buyers

Every week, someone tells us they are "thinking about New Hampshire." They live in Wellesley or Newton or Concord, MA. They earn a good salary. They know New Hampshire has no income tax. But they have never actually run the numbers. This analysis does it for them.

We modeled the total tax burden for a household earning $500,000 annually, purchasing a $900,000 home. The comparison is between a representative Massachusetts town (Wellesley) and a Souhegan Valley community (Amherst, NH). All figures use 2026 tax rates.

Income Tax: The Big Number

Massachusetts imposes a flat 5% income tax on earned income, plus an additional 4% surtax on income above $1 million (the "millionaire's tax" passed in 2022). For a household earning $500,000, the Massachusetts income tax bill is approximately $25,000 per year.

New Hampshire charges zero income tax on wages and salary. The state's former interest and dividends tax was fully repealed effective January 1, 2025. The savings on income tax alone: $25,000 annually.

Property Tax: The Offset

This is where New Hampshire gives some of it back. New Hampshire property taxes are among the highest in the nation, and this is the number that causes sticker shock for Massachusetts buyers. Here is the honest comparison:

Tax Category	Massachusetts (Wellesley)	New Hampshire (Amherst)
Property Tax Rate	$10.82 per $1,000	$24.56 per $1,000
Property Tax on $900K Home	$9,738	$22,104
Income Tax (on $500K)	$25,000	$0
Sales Tax (est. $30K spending)	$1,875	$0
Total Annual Tax Burden	$36,613	$22,104
Annual Savings in NH	$14,509

Yes, property taxes in Amherst are more than double what you would pay in Wellesley. But the elimination of income tax and sales tax more than compensates. The net savings of approximately $14,500 per year is not a rounding error — it is a new car every two years, or $145,000 over a decade.

Sales Tax: The Invisible Savings

Massachusetts charges a 6.25% sales tax on most purchases. New Hampshire charges nothing. For a household spending $30,000 annually on taxable goods — clothing above $175, electronics, furniture, home improvement — that is an additional $1,875 saved per year.

This may seem small next to the income tax number, but it compounds. Every appliance, every piece of furniture for that new home, every car purchase — all tax-free in New Hampshire.

The Hidden Advantages

The tax comparison table covers the major line items, but there are additional savings that do not show up in a simple comparison:

• Vehicle registration: Massachusetts excise tax on a $60K vehicle runs approximately $1,500 per year. New Hampshire registration fees are substantially lower.
• Home prices: A $900K property in Amherst buys a 3,500+ sq ft colonial on 2+ acres. In Wellesley, that same $900K gets a 1,800 sq ft ranch on a quarter acre.
• Insurance: Homeowner's insurance rates in NH are generally 15-25% lower than comparable Massachusetts coverage.
• No mandatory auto insurance minimums: While we recommend full coverage, New Hampshire is the only state that does not require auto insurance. This gives you negotiating leverage with insurers.

The 10-Year View

At $14,500 per year in savings, invested at a conservative 6% annual return, a Massachusetts-to-New-Hampshire relocator accumulates approximately $197,000 over 10 years that they would have otherwise paid in taxes. For a household earning above $500K — common among physician and tech executive buyers in the Souhegan Valley — the numbers scale proportionally.

The Trade-Offs (Honest Assessment)

No analysis is complete without acknowledging what you give up. New Hampshire's property tax rates are high, and they fund local services directly — including schools. The quality of those services varies by town, which is why communities like Amherst with top-ranked schools command premium prices.

New Hampshire also has no state-level social safety net comparable to MassHealth. If you are relying on state-funded services, the calculus changes. For high-income households, however, the math is overwhelmingly in New Hampshire's favor.

The Souhegan Valley specifically offers the best of both worlds: New Hampshire tax advantages with a direct commute to Boston's employment centers. That combination is why prices in our 10-community corridor continue to appreciate faster than the state average.
