Does New Hampshire tax wages?

No. New Hampshire has never imposed a tax on earned wages or salaries. Your only mandatory paycheck taxes are federal income tax withholding and FICA, so NH take-home pay on a salary is the same as in a fully no-income-tax state.

What happened to the NH Interest and Dividends Tax?

New Hampshire historically taxed investment income (interest and dividends) at 5%, but the rate was phased down and the tax was fully repealed effective January 2025. From the 2025 tax year onward, New Hampshire has no income tax of any kind.

How is Social Security tax calculated?

Social Security is 6.2% of wages up to the annual wage base of $176,100 for 2025. Earnings above that cap are not subject to Social Security tax, so high earners pay a fixed maximum amount.

How is Medicare tax calculated?

Medicare is 1.45% of all wages with no cap. An Additional Medicare Tax of 0.9% applies to wages above $200,000 (single) or $250,000 (married filing jointly).

Is my salary data sent anywhere?

No. All calculations run entirely in your browser using the 2025 federal tax tables. Nothing you type is transmitted or stored anywhere.

New Hampshire Payroll Calculator

New Hampshire has never taxed earned wages, and as of January 2025 its old Interest and Dividends Tax is fully repealed — so the state now has no income tax of any kind.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 it works

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.
