How this calculator works
New Hampshire has no state tax on wages or personal income, so your paycheck deductions are federal income tax and FICA only. This calculator takes your gross pay, subtracts any pre-tax 401(k) and health-insurance deductions, computes federal income tax and FICA on what’s left, and divides the year’s total by your number of pay periods to estimate what lands in your account each paycheck.
The formula
grossAnnual = salary, or hourlyRate × hoursPerWeek × 52
ficaWages = grossAnnual − pretaxHealth (401(k) does NOT reduce FICA wages)
fedTaxableWages = grossAnnual − pretaxHealth − 401(k) contribution
taxableIncome = max(0, fedTaxableWages − standardDeduction)
FICA = 6.2% of ficaWages (up to the $184,500 wage base)
+ 1.45% of ficaWages (no cap)
+ 0.9% of ficaWages over $200,000
federalTax = 2026 bracket engine applied to taxableIncome
stateTax = $0 (New Hampshire has no tax on wages or salary income)
net = grossAnnual − pretaxHealth − 401(k) − FICA − federalTax − stateTax − postTaxDeductions
netPerPaycheck = net / payPeriodsPerYear
Worked example
A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:
- FICA: 7.65% × $60,000 = $4,590.00/year ($3,720 Social Security + $870 Medicare)
- Taxable income: $60,000 − $16,100 standard deduction = $43,900 → federal tax = $5,020.00/year
- Net pay: $60,000 − $4,590 − $5,020 = $50,390.00/year, or $1,938.08 per biweekly paycheck
This is the same arithmetic as our Texas, Florida, Washington, Tennessee, and Nevada calculators’ worked examples, since all six states have $0 state tax on wages; only the state-specific content differs. New Hampshire’s now-repealed Interest and Dividends Tax never applied to wages in the first place, so it has no effect on this result either, before or after its January 1, 2025 repeal.
Frequently asked questions (FAQ)
Does New Hampshire have a state income tax on wages or salary?
No. New Hampshire has never levied a broad-based tax on wages or salaries. Unlike some other no-tax states, there is no single constitutional clause that bars one; New Hampshire has simply never enacted a general wage income tax, relying instead on property taxes, business taxes, and targeted taxes like the rooms and meals tax to fund state government.
What was the New Hampshire Interest and Dividends Tax, and is it really gone?
It was a 3% tax on interest and dividend income above $2,400 (individual) or $4,800 (joint), never on wages. Passed for repeal in 2023 under House Bill 2, it was phased down from 5% and fully eliminated for tax periods starting January 1, 2025. The NH Department of Revenue Administration confirms no 2025 return is required.
Does New Hampshire tax anything else instead of wages?
Yes. New Hampshire funds itself mainly through local property taxes, the Business Profits Tax and Business Enterprise Tax on companies, and a rooms and meals tax on lodging and prepared food. None of these are withheld from an employee paycheck, so none of them affect the result on this calculator.
What is FICA?
FICA is the combined 7.65% Social Security (6.2%) and Medicare (1.45%) tax withheld from your paycheck, matched by your employer. Social Security stops once your wages hit the annual wage base ($184,500 for 2026); Medicare has no cap and adds an extra 0.9% above $200,000.
How does contributing to a 401(k) change my take-home pay?
A traditional 401(k) contribution lowers the wages your federal income tax is calculated on, so it shaves a bit off your income tax bill, but it does not reduce your Social Security or Medicare wages, since those are calculated before the 401(k) deduction.
Why doesn't my calculated net pay match what shows up in my actual paycheck?
This calculator estimates your annual tax liability and divides it evenly across your pay periods. Your actual employer withholds federal tax per paycheck using IRS withholding tables, which can differ slightly period-to-period; the two methods land close together but rarely to the exact cent.
