New Hampshire has never taxed earned wages, and as of January 2025 its old Interest and Dividends Tax is fully repealed — so the state now has no income tax of any kind. Your paycheck deductions are limited to federal income tax withholding and FICA — Social Security and Medicare. This free calculator estimates your New Hampshire take-home pay.
How take-home pay is computed
The calculator applies the 2025 federal payroll rules in order:
- Pre-tax deductions (such as 401(k) contributions) are subtracted from gross pay to find your federal taxable wages.
- Federal income tax is computed by subtracting the standard deduction ($15,000 single, $30,000 married filing jointly for 2025) and applying the seven progressive federal brackets.
- Social Security is 6.2% of wages up to the $176,100 wage base.
- Medicare is 1.45% of all wages, plus an extra 0.9% on wages above the high-earner threshold.
Your net pay is gross pay minus federal income tax, Social Security and Medicare. Because New Hampshire now adds nothing, the result is simply your federal after-tax pay.
The 2025 Interest and Dividends Tax repeal
For decades New Hampshire was a partial exception among no-income-tax states: it taxed wages at zero but levied a 5% Interest and Dividends Tax on investment income. That tax was phased down over several years and fully eliminated from the 2025 tax year. From 2025 onward, NH residents owe no state tax on wages, interest, dividends, or capital gains — putting it fully alongside states like Florida and Texas for income-tax purposes.
Example
A single filer earning $80,000 with no pre-tax deductions: taxable income after the $15,000 standard deduction is $65,000. Federal income tax across the 2025 brackets is roughly $9,400, Social Security is $4,960, and Medicare is $1,160. Net annual take-home is about $64,480, or roughly $5,373 per month.
Notes
The catch: New Hampshire’s property taxes
“No income tax” does not mean “low tax”. New Hampshire funds most public services — including schools — through some of the highest property taxes in the United States rather than an income or general sales tax. A take-home figure that looks generous on paper can be offset by a large annual property-tax bill if you own a home in the state. This calculator models only paycheck deductions; weigh property tax separately when comparing a New Hampshire offer against a state with income tax but lower property rates.
Which 2025 figures to re-check next year
The federal parameters below are re-indexed for inflation each year, so re-confirm them for the relevant tax year:
| Parameter (2025) | Value |
|---|---|
| Standard deduction (single) | $15,000 |
| Standard deduction (married filing jointly) | $30,000 |
| Social Security wage base | $176,100 |
| Social Security rate | 6.2% (to the wage base) |
| Medicare rate | 1.45% (no cap) + 0.9% high-earner surtax |
The FICA rates are fixed by law and rarely change; the thresholds and standard deduction move every year.
Comparing a New Hampshire offer against a neighboring state
The zero-income-tax headline is most useful when comparing offers across the border. A Massachusetts employer withholds the state’s flat income tax from wages; the same salary earned by a New Hampshire resident working remotely in New Hampshire keeps that slice. But two caveats keep the comparison honest: New Hampshire funds services through some of the country’s highest property taxes, so the total tax picture depends on whether you rent or own and where; and if you commute into another state, that state generally taxes the wages you earn there — living in NH only shelters income sourced to NH. Run the gross-to-net comparison here, then weigh housing costs and commute-state tax before treating the NH offer as automatically ahead.
Note also that “no income tax” has never meant “no payroll deductions”: FICA applies in every state, and pre-tax benefits (401(k), health premiums, HSA) reduce federal taxable wages in New Hampshire exactly as elsewhere, so two NH offers with different benefit structures can produce meaningfully different take-home even at identical salaries.
