Welcome to our payroll calculator!

Before we jump in, who are you using this calculator for?


Our calculators are designed for employers, and they’ll ask for information you may not have. For a better experience, please check out this employee-focused paycheck calculator.

How much did your employee earn?

Gross Pay: This is the total amount of wages your employee earned before taxes and deductions are withheld.

For salaried employees, gross pay equals their annual salary divided by the number of pay periods per year. For hourly employees, gross pay equals the number of hours worked multiplied by their hourly wage.

(Don’t forget to add on any tips, commissions, or bonuses!)

Gross Pay Method: Is the gross pay amount based on your employee’s annual compensation, or by how many hours they worked in the last pay period?

Gross Pay YTD: Enter the total gross pay your employee has earned this year, prior to this paycheck. Normally, this can be found on the last pay stub.

Pay Frequency: How often do you normally issue paychecks?

Check Date: Enter the check date that should appear on your paycheck.

Is your employee exempt from any taxes?

Federal: In some cases, public and governmental employees are exempt from federal taxes. Check “yes” if your employee is exempt and Federal taxes should not be deducted.

FICA: In some cases, public and governmental employees are exempt from FICA. Check “yes” if your employee is exempt and FICA taxes should not be deducted.

Medicare: In some cases, public and governmental employees are exempt from Medicare taxes. Check “yes” if your employee is exempt and Medicare taxes should not be deducted.

Please enter your employee’s withholding information.

2020 W4: Would you like to use the 2020 withholding tables? Here’s an article that covers the 2020 W-4 updates if you aren’t sure.

Federal Filing Status: Select your employee’s filing status for federal withholding. This helps determine how much federal tax will be withheld.

Two Jobs: If the employee indicated that they have more than one job or are married and filing jointly with a working spouse, select Yes here.

Dependents Amount: Enter the amount your employee listed on Line 3 of their W-4, if any. This is where they claim dependents.

Other Income: If your employee listed another other income on line 4(a) of their W-4, enter the amount here.

Deductions: Enter any deductions that your employee listed on line 4(b) of their W-4, if applicable.

Additional Federal Withholding: If your employee has asked to have additional funds withheld from each paycheck, enter the amount here. If they have not, enter “0”.

Round Federal Withholding: Would you like us to round your employee’s withholding totals to the nearest dollar? (It’s not required, but it is permitted)

Now, add information for their state.

State: Select the state where withholding should be calculated. It should be the same state where the work was performed.

Now, add locale information if applicable.

Does your employee have any voluntary deductions?

Please add any additional deductions for items like health insurance, 401(k), HSAs/FSAs, or any other benefits.

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 $168,600 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.
Payroll call-to-action

Staying compliant

Did you know that almost all employers in the state must carry workers’ compensation? Learn more about who needs coverage, the benefits it provides, and how to get a policy in our employer’s guide to New Hampshire workers’ compensation.

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. Find further information on employment tax due dates from the IRS here.

More payroll calculators for New Hampshire businesses

Employers in New Hampshire can use the calculator at the top of this page to quickly calculate their employees’ gross pay, net pay, and deductions in a few clicks. 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. So, if you need a little more help with the number-crunching, check out some of the calculators below.
