Every relocation conversation involving New Hampshire eventually arrives at the same headline: no income tax. It is true, and as of New Hampshire Department of Revenue Administration guidance, it became even more true on January 1, 2025, when the state's remaining Interest and Dividends Tax was fully repealed. But the honest answer to "how much does this actually save me" requires more than the headline. It requires running the math on income tax, sales tax, and property tax together, because New Hampshire's property tax rates are genuinely higher than Massachusetts's or Connecticut's, and that fact gets lost in casual conversation far too often.
This article runs that full math across four income levels, compares Massachusetts and Connecticut separately since their tax structures are meaningfully different, and shows what the savings look like compounded over a 10-year hold. The goal is not to oversell New Hampshire. It is to give buyers the real number so they can make the decision with full information.
What New Hampshire Actually Taxes
New Hampshire has no tax on wage or salary income, full stop. Until the end of 2024, the state did tax interest and dividend income above a $2,400 individual exemption ($4,800 for joint filers) at a 3% rate — a tax that mattered for retirees and investors with substantial taxable investment income but not for most working households. That tax has now been eliminated entirely. As of 2025, New Hampshire collects zero state-level tax on any form of personal income: wages, interest, dividends, or capital gains.
The state also has no general sales tax. Massachusetts charges 6.25% and Connecticut charges 6.35% on most retail purchases. For a household spending $40,000 a year on taxable goods and services, that difference alone is $2,500 to $2,540 annually — a number that rarely makes it into relocation conversations but adds up over a decade.
What New Hampshire does tax: property, at rates that run meaningfully higher than Massachusetts and somewhat higher than Connecticut on average. The state funds schools and municipal services primarily through property tax in the absence of income or sales tax revenue. This is the offset that has to be modeled honestly, not glossed over.
The Income Tax Math, by Income Level
Massachusetts taxes income at a flat 5% rate, with an additional 4% surtax (the "Millionaire's Tax") on income above $1 million, bringing the marginal rate to 9% above that threshold. Connecticut uses a progressive structure with seven brackets ranging from 3% to 6.99%, meaning the effective rate on a given income depends on how that income is distributed across the brackets, not just the top marginal rate.
| Household Income | MA State Income Tax (5% flat) | CT State Income Tax (effective rate) | NH State Income Tax | Annual Savings vs. MA |
|---|---|---|---|---|
| $150,000 | $7,500 | ~$6,800 | $0 | $7,500 |
| $250,000 | $12,500 | ~$12,400 | $0 | $12,500 |
| $400,000 | $20,000 | ~$21,600 | $0 | $20,000 |
| $750,000 | $37,500 | ~$43,500 | $0 | $37,500 |
The Connecticut effective rates above are approximate and depend on filing status, deductions, and exact bracket allocation — they are directionally accurate for illustration but a household's actual liability should be modeled with a tax professional using their specific return. The pattern holds regardless of the precise figures: Connecticut's progressive structure generally produces a higher effective rate than Massachusetts's flat 5% for income above roughly $200,000, which means the New Hampshire savings case is typically stronger for households relocating from Connecticut than from Massachusetts at the same income level.
The Property Tax Offset, Calculated Honestly
This is the part of the conversation that gets skipped most often, and skipping it is a disservice to buyers making a six-figure decision. New Hampshire's average effective property tax rate runs from approximately 1.61% to 2.20% of assessed value depending on the town — among the highest in the country by most rankings, including the Tax Foundation's state property tax comparisons. Massachusetts averages closer to 1.10%, and Connecticut averages roughly 1.79%.
On a $700,000 home, the dollar difference between a 1.10% Massachusetts rate and a 1.90% New Hampshire rate (a reasonably representative Southern NH town rate) is approximately $5,600 per year. That is a real number and it meaningfully offsets the income tax savings, particularly at lower income levels.
Net Annual Tax Savings, NH vs. MA, by Household Income (After Property Tax Offset)
Illustrative model assuming a $700K home and a representative Southern NH property tax rate of ~1.9% vs. a representative Eastern MA rate of ~1.1%. Actual figures vary by specific town and home value. Data current as of June 2025; verify current rates before making a purchase decision.
The net result, after subtracting the property tax differential from the income tax savings, is what actually matters for the decision. At $150,000 in household income, the $7,500 income tax savings is mostly or entirely offset by the property tax increase on a comparable home, making the tax case alone fairly weak. At $400,000, the $20,000 income tax savings comfortably exceeds the property tax differential, leaving meaningful net savings even after the offset. The crossover point — where income tax savings clearly outweigh the property tax increase — generally falls somewhere in the $200,000 to $250,000 household income range, though the exact threshold depends on the specific home values and towns being compared.
Why the Town Choice Matters as Much as the State Choice
New Hampshire property tax rates vary significantly by town, sometimes by a full percentage point or more between neighboring municipalities, because each town sets its own rate based on local school funding needs and the size of its commercial tax base. A buyer choosing between two otherwise-comparable Southern NH towns can face a meaningfully different property tax bill purely based on that choice, independent of the state-level tax advantage. This is one of the most overlooked variables in NH relocation decisions — the state-level savings is fixed, but the property tax offset is not, and buyers who shop the town-level rate as carefully as the home itself capture more of the available savings.
Rates shown above are illustrative and approximate as of the 2024 tax year; New Hampshire towns set new rates annually each fall, and buyers should verify the current rate directly with the relevant town tax assessor's office before finalizing a purchase decision.
The right town changes your effective tax rate as much as the right state does — and most buyers never model it.

The 10-Year Compounding Case
The annual savings figure understates the long-term value of the New Hampshire move, because the savings itself can be invested rather than absorbed into higher discretionary spending. A household earning $250,000 that nets approximately $9,000 to $10,000 in annual tax savings after the property tax offset, and invests that difference annually at a conservative 7% average market return, accumulates roughly $130,000 to $145,000 in the investment account alone after 10 years — separate from any equity gained on the home itself.
For a household at the higher end of the income range modeled here — $400,000 and net annual savings closer to $14,000 to $15,000 after offset — the same 10-year compounding math produces an accumulated value in the $195,000 to $210,000 range. This is the case that often gets missed in a simple year-one comparison: the New Hampshire tax advantage is not a one-time savings, it is a recurring annual deposit into whatever the household chooses to do with it, and the compounding effect over a typical homeownership horizon is substantial.
Who the New Hampshire Move Makes the Most Sense For
The tax case is strongest for households earning above $250,000, for households with significant investment income or capital gains exposure (since New Hampshire taxes none of it at the state level), and for households relocating specifically from Connecticut rather than Massachusetts, given Connecticut's higher effective rate at upper-middle income levels. It is also stronger for households who plan to remain in the home for seven or more years, since the compounding benefit of the annual savings takes time to materially exceed any one-time moving and transaction costs.
The tax case is weaker, though not necessarily disqualifying, for households earning below $150,000, for households purchasing a home well above their income-appropriate price point (since the property tax offset scales with home value, not income), and for households who place a higher priority on Massachusetts or Connecticut's specific town amenities, school district reputations, or commute profiles than on the tax differential itself. Tax savings should inform the decision. They should rarely be the only factor in it.
