New Hampshire Bonus Pay Tax Calculator
Estimate a New Hampshire employee's net bonus with 2026 federal supplemental-wage methods, Social Security and Medicare thresholds, zero New Hampshire wage-income withholding, optional voluntary PFML deductions, employer unemployment cost, and net-to-gross planning.
Bonus inputs
Use gross-to-net for a planned bonus or net-to-gross when a take-home amount was promised. This tool is limited to one-time or nonperiodic taxable cash bonuses; use a full paycheck calculation for regular or periodic wages, commissions, and overtime.
Federal aggregate settings (Form W-4 2020 or later)
Aggregate estimates use the 2026 automated percentage method for a Form W-4 from 2020 or later. A 2019-or-earlier W-4, exempt employee, nonresident alien, or earlier same-period supplemental payment requires payroll review.
New Hampshire wage-tax treatment
New Hampshire wage-income withholding is $0. The New Hampshire Department of Revenue Administration states that the state does not tax an individual's reported W-2 wages. The former Interest and Dividends Tax was repealed for taxable periods beginning after December 31, 2024. Federal income tax and FICA still apply, and another state may require withholding for a multistate employee.
Employer cost and voluntary PFML settings
New Hampshire UI, FUTA, employer FICA, and any employer PFML premium are employer costs. They never reduce take-home. Employer cost is partial until a contributing employer's current combined NHES rate is entered. A worker-paid PFML amount is an optional post-tax insurance deduction, not a tax.
What this calculator includes
Model the optional 22% method, the mandatory 37% rate above the $1 million threshold, and the aggregate method using the 2026 Publication 15-T automated tables for a Form W-4 from 2020 or later.
Show state wage-income withholding at $0 and use a clearly labeled $0 local-tax modeling assumption while still calculating federal income tax, Social Security, Medicare, and Additional Medicare withholding. Review another jurisdiction separately when applicable.
Test New Hampshire UI and FUTA against distinct wage bases, and include NH PFML only when actual employee or employer policy amounts are entered.
This is a 2026 estimate for an ordinary taxable cash bonus paid to a W-2 employee. It is not a final tax-return calculation, legal opinion, or taxability determination. Pretax benefits, retirement deferrals, garnishments, special wage exclusions, nonresident-alien adjustments, multistate withholding, and payroll-provider rounding can change the actual paycheck.
New Hampshire bonus withholding FAQ
Does New Hampshire withhold income tax from a bonus?
No. New Hampshire does not tax an individual's reported W-2 wages, so the state wage-income withholding line is $0.
What happened to the Interest and Dividends Tax?
It was never a wage tax and was repealed for taxable periods beginning after December 31, 2024. It does not create bonus withholding in 2026.
When can an employer use the federal 22% method?
It is optional for an eligible separately paid or separately identified supplemental amount when federal income tax was withheld from regular wages in the current or immediately preceding year.
When does the federal 37% rate apply?
The excess portion is subject to mandatory 37% withholding and the threshold includes common-control businesses. Employers may elect 37% on the entire payment that crosses the threshold; this calculator uses the excess-only split.
Does New Hampshire unemployment insurance reduce take-home?
No. It is employer-funded. Bonuses are wages, the annual taxable base is $14,000, and the current combined NHES rate should come from the employer's report. The rate field starts blank so an unverified Q3-Q4 or employer rate is not invented.
Is NH PFML a mandatory payroll tax?
No. It is voluntary insurance. The calculator defaults both employee and employer amounts to $0 and accepts actual policy-based dollar amounts when applicable.
Why are Social Security and Medicare wages separate?
Social Security stops at $184,500 in 2026, while Medicare has no cap and Additional Medicare withholding begins when this employer pays more than $200,000.
Can this calculator gross up a promised net bonus?
Yes. Net-to-gross mode solves the gross amount under the selected federal method, FICA, and any entered employee PFML deduction.
