Beyond HCM — New Hampshire Final Pay Calculator (2026)

© 2026 Beyond HCM — For estimation purposes only. Not legal/tax advice.

If calculating a departing employee’s final paycheck sounds daunting, don’t worry. The New Hampshire final pay calculator helps employers estimate an off-cycle paycheck for employees who are leaving the company. Simply enter the employee’s gross wages earned during the final pay period, along with any PTO payout, severance, and withholding details, and the calculator will estimate applicable taxes and net pay in just a few seconds. Because New Hampshire does not impose state income tax on employee wages, this calculator does not include state withholding and instead focuses on federal withholding and FICA taxes. This version is designed to provide a clear estimate of federal income tax, Social Security, and Medicare withholding using an annualized wage approach. For 2026, New Hampshire continues to have no state tax on wage income, and the Interest and Dividends Tax has been fully repealed, so employee paychecks are generally only subject to federal payroll taxes and any applicable pre-tax deductions.

Final Paycheck Rules for Employers

Is There a Federal Rule for Final Paychecks?
It may come as a surprise, but the federal government does not establish a single nationwide deadline for when final paychecks must be issued. In practice, final paycheck timing is generally governed by state law, which is why employers should review the rules that apply in the state where the employee worked.

 

New Hampshire Final Paycheck Rule
New Hampshire does have specific final paycheck timing rules. In general, when an employee is terminated, all wages due must typically be paid within 72 hours. If an employee resigns, final wages are generally due by the next regular payday.

 

Because New Hampshire law establishes different timing requirements depending on whether the employee was terminated or resigned, employers should make sure all final earnings are properly calculated and issued within the required timeframe.

 

Important Final Paycheck Considerations
Even when an employee is terminated, employers generally cannot withhold wages that have already been earned except where a lawful deduction applies. A final paycheck should include all compensation due through the employee’s last day worked, subject to applicable payroll deductions and withholding rules.

 

Employers should also review whether the employee is entitled to payment for accrued or unused vacation or PTO. In New Hampshire, payout of unused vacation or PTO at separation is generally determined by the employer’s written policy, handbook provisions, or employment agreement rather than a universal state requirement. Employers should review their policies carefully before processing a final check.

 

If severance is being paid, it is generally treated as taxable wages for federal withholding purposes. Employers should also remember that New Hampshire does not impose state income tax on wages, so final pay is generally subject only to federal income tax withholding, Social Security, and Medicare.

 

Because final paycheck rules and payroll tax requirements can vary depending on the situation, employers should confirm the rules that apply to their business and workforce before processing a final check.
