Across one street: Massachusetts' 5% rate, 4% millionaire surtax and 0.46% paid-leave levy against New Hampshire's zero. At $100,000 of gross wages a single filer takes home $73,940 in Massachusetts and $79,180 in New Hampshire — a difference of $5,240 a year — about $437 a month. The federal tax and FICA lines are identical in both states; every dollar of the difference is state withholding.
Three salary levels, both states
A single tax difference does not scale linearly, because both states are progressive to some degree (or flat). The table recomputes the whole paycheck at each salary rather than applying one percentage.
| Gross salary | Massachusetts withholding | Massachusetts nets | New Hampshire withholding | New Hampshire nets | Difference |
|---|---|---|---|---|---|
| $60,000 | $12,666 | $47,334 | $9,610 | $50,390 | +$3,056 |
| $100,000 | $26,060 | $73,940 | $20,820 | $79,180 | +$5,240 |
| $150,000 | $44,179 | $105,821 | $36,209 | $113,791 | +$7,970 |
Notice the difference grows faster than the salary once you pass both states’ middle bands — that is the progressive part doing the work. At the low end the two states can be within a few hundred dollars of each other even when their headline top rates look far apart, because the top rate only applies to the slice of income above the last threshold.
What actually changes on the state line
| Massachusetts | New Hampshire | |
|---|---|---|
| Income tax structure | Progressive brackets | No state income tax |
| Top marginal rate | 9.00% | 0.00% |
| Standard deduction used here | $0 | $0 |
| State payroll deductions (SDI / paid leave) | payroll 0.46% | None |
The payroll row matters more than people expect. A state with no income tax is not automatically the cheaper state: Massachusetts withholds New Hampshire withholds nothing extra. These are wage deductions, so they hit a W-2 salary but not self-employment income — which is why the same two states can rank differently for a freelancer.
Moving costs versus the annual difference
A move is not free. Using a conservative $8,000 for truck, deposits and travel, the paycheck difference alone takes about 18 months to pay back. Anything shorter than a year is usually worth doing on the numbers alone; anything longer than three years needs a reason other than tax.
What this comparison leaves out
- Pay scales differ by state. The same job title frequently pays 10–30% more in Massachusetts than in New Hampshire, or the reverse. A lower tax rate on a lower salary can still net less; this page holds the salary constant on purpose so the tax effect is visible.
- Property tax, sales tax, and rent. None of them appear on a pay stub, and in several no-income-tax states they are the mechanism that replaces the income tax.
- Local income taxes. County, city and school district income taxes exist in a number of states; this dataset models state-level tax only.
- Part-year residency. The year you move, you file in both states and apportion income by residency dates. That year is never the clean annual comparison shown above.
- Remote work and the convenience rule. If your employer is in Massachusetts while you live in New Hampshire, some states still tax your wages at the employer’s location. Check the reciprocity agreement between the two states before treating the move as a tax change.
Other moves
Questions this page answers directly
- Will my paycheck change the first month after I move?
- Only after you update your address and state withholding form with payroll. Until then the old state keeps withholding, and you reconcile on the state return.
- Do I pay Massachusetts tax on income earned before the move?
- Yes. The year of the move is split by residency dates: Massachusetts taxes the income earned while you were a resident (and often the wages earned there while working there), and New Hampshire taxes the rest. Both states will want a return.
- Is the difference really only state tax?
- At the same gross salary, yes. Federal brackets, FICA rates and the Social Security wage base are identical in both states. Nothing about your federal return changes except your address.
- What if I am self-employed?
- The payroll deductions shown above do not apply to you, and both states tax net self-employment income differently from wages. Start from the state-by-state self-employment pages instead.
