To outsiders, South Dakota is all about that giant sculpture carved on the side of a mountain. To insiders, there’s a whole lot more to the state than Mount Rushmore. You kind of feel bad for people who have never tasted kolache, chislic, or kuchen. But what definitely makes you pull your hair out as a small business owner is having to deal with payroll taxes.

Federal Payroll Taxes

While a 0% state income tax is saving you from some calculations, you are still responsible for withholding and paying federal payroll taxes. Luckily, our South Dakota payroll calculator is here to assist with calculating your federal withholding and any additional contributions your business is responsible for.


Here’s a quick overview of what you need to know when you’re calculating federal payroll taxes. If you would like to see each step in detail, you can click here to read our step-by-step federal income tax guide.


  • Calculate Employee Gross Wages:
    • For all your hourly employees, multiply their hours worked by the pay rate. And don’t forget to increase the rate for any overtime hours worked!
    • For all your employees on salary, divide each employee’s annual salary by the number of pay periods you have.
    • Be sure to add in commissions, bonuses, and tips. They are added to gross wages as well.
  • Subtract Pre-Tax Withholdings (if any):
    • If your employee contributes to a Flexible Spending Account (FSA), 401(k) retirement savings account, or any other eligible pre-tax withholding accounts, subtract the amount from their gross pay prior to applying payroll taxes.
  • Deduct Federal Income Tax:
    • Federal income tax ranges from 0% to 37%. This is the biggest tax of them all. We won’t get into the nitty-gritty in this guide, but you can find all the IRS withholding information you need here.
  • Deduct and Match FICA Taxes:
    • Social Security Tax: You will need to withhold 6.2% of each employee’s taxable wages up until they have reached a total earning of $160,200 for 2023. As an employer, it is your responsibility to match this tax.
    • Medicare Tax: You will also need to withhold 1.45% of each employee’s taxable wages up until they have reached a total earning of $200,000 for 2022. You will need to match this tax as well. For employees who earn salaries above $200,000, withhold what’s called the Additional Medicare Tax, which is 0.9%. Only the employee is responsible for paying the Additional Medicare Tax.
  • Pay FUTA Unemployment Tax:
    • You as the employer will pay 6% of each employee’s first $7,000 of taxable income. Employees are not responsible for paying the FUTA tax. Note that if you pay state unemployment taxes in full and on time, you are eligible for a tax credit of up to 5.4%. So be extra diligent here!
  • Subtract Post-Tax Deductions (if any):
    • Not many of your employees will have post-tax deductions, but you may be asked to deduct court-ordered wage garnishments, child support, post-tax contributions to savings accounts, elective benefits, etc.

2023 South Dakota (SD) State Payroll Taxes

You already know that the State of South Dakota charges a 0% income tax. And even better, no cities within the state charge a local income tax. It’s definitely nice to have one less thing to worry about.


Payroll call-to-action

South Dakota State Unemployment Insurance (SUI)

As an employer in South Dakota, you are responsible for paying unemployment insurance to the state. In 2023, the rate ranges from 0% all the way up to 9.5% on the first $15,000 in wages paid to each employee in a calendar year.


If you’re a new employer, you will pay 1.2%. New construction employers will have to pay 6%.


Remember, be sure to pay your SUI in full and on time so you can be eligible for the FUTA tax credit!

Cut Those Paychecks!

That’s it! You’ve checked “payroll taxes” off your to-do list so you can focus on growing your business. Once each employee’s net pay is calculated (taking deductions and withholdings into consideration), you’re in the clear.


All you have to worry about is getting your employees paid on time as well as setting aside whatever you owe in FICA and UI taxes. The numbers can add up quickly if you don’t pay close attention to them!


You will need to use Form 941 to file federal taxes quarterly, and Form 940 to report your annual FUTA tax. You can pay taxes online using the EFTPS payment system. More details about employment tax due dates can be found here.
