Federal payroll taxes for New Hampshire employers
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 $176,100 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.

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). You will need to fill out Forms 940 (annually) and 941 (quarterly), but if you prefer ongoing fulfillment, payment can be made via the EFTPS payment system.

But sometimes there’s a little more math to do before they are able to cut paychecks. For example, do you own a small business where employees earn tips from customers? Remember that you are responsible for withholding taxes from your employees’ paychecks based on the tips they receive. Also, if you have workers who leave from time to time, you may need to spend some time calculating their final paychecks.
