As one of the original 13 and the first colony to declare independence from the British, it’s no surprise that New Hampshire’s state motto is Live Free or Die. As a small business owner in the state, you share this independent spirit. You want to focus on living free and growing your small business instead of having to deal with payroll taxes. Luckily, since New Hampshire doesn’t collect state income tax, it’s one less thing that you have to worry about. But you can’t forget about federal taxes.

Federal Payroll Taxes

Here’s a quick overview of what you need to know when you’re calculating federal payroll taxes. For a more in-depth discussion on each of the federal payroll tax items, check out our step-by-step guide.


  • Gross Wages:
    • For all your hourly employees, multiply their hours worked by the pay rate…and don’t forget to add any overtime hours worked!
    • For all your employees on salary, divide each employee’s annual salary by the number of pay periods per year.
    • Remember to add in commissions, bonuses, and tips into gross wages as well.
  • Deduct Pre-Tax Withholdings if your employees contribute to 401(k), FSA, HSA, or other pre-tax withholdings. You will subtract their contributions from gross wages before applying payroll taxes.
  • Deduct Federal Income Tax, which ranges from 0% to 37%. We won’t get into the nitty-gritty here, but you can find detailed withholding information through the IRS website.
  • Deduct FICA Taxes (and Match):
    • For Social Security tax, withhold 6.2% of each employee’s taxable wages up until they have earned a total of $160,200 for the year. As an employer, you also need to pay this tax.
    • For Medicare tax, withhold 1.45% of each employee’s taxable wages up until they have reached a total earning of $200,000 for that year. You will also pay this tax. For employees who make salaries above $200,000, withhold an Additional Medicare Tax of 0.9%. Only the employee is responsible for paying the Additional Medicare Tax.
  • Pay FUTA Unemployment Tax, which is 6% of the first $7,000 of taxable income for each of your employees. Only employers are responsible for paying FUTA taxes. However, if you pay state unemployment taxes on time and in full, you are eligible for a tax credit of up to 5.4%, making your FUTA tax bill effectively 0.6%. It’s a huge saving, so make sure you pay attention!
  • Subtract Post-Tax Deductions, such as child support, court-ordered wage garnishments, etc. If applicable, you will receive a letter from the court stating the amount of the deduction.

New Hampshire’s income tax is pretty simple with a flat rate of 5%, and no local income taxes.

New Hampshire Unemployment Insurance

As an employer, you’re responsible for paying unemployment insurance. For 2023, New Hampshire unemployment insurance rates range from 0.1% to 8.5% with a taxable wage base of up to $14,000 per employee per year.


New employers should use 2.7%.


The state has the right to adjust its rates quarterly, so look out for notices to make sure you pay the right taxes each quarter.


And remember to pay your state unemployment insurance on time so that you can get the big FUTA tax credit!


Now Write Your Employees’ Paychecks!

You’re almost at the finish line! Now get your signature ready because after you’ve calculated your employees’ net pay by implementing all deductions, it’s time to write those checks.


All you have to worry about is paying your employees on time and setting aside any taxes your company is responsible for (FICA and UI payments, we’re looking at you).
