Updated January 14, 2021


According to the Small Business Administration, over 99% of businesses in Mississippi are small businesses. A quarter-million small businesses call Mississippi home, and they all share one thing in common: they all have to deal with payroll taxes. Luckily, our neat (if we can say so ourselves) payroll calculator is here to help you avoid any payroll tax fiascos for your small business. Whether you own an old-school diner in Jackson, a trendy cafe in Biloxi, or a souvenir store near Elvis’s birthplace, our free calculator can help any Mississippi business get payroll right.


The process is simple. All you have to do is enter each employee’s wage and W-4 information, and the calculator will process their gross pay, deductions, and net pay for both Mississippi and Federal taxes.

Federal Payroll Taxes

First and foremost, we will walk through a quick overview of federal payroll taxes that all employees have to pay. However, if you would like to see each step in detail, head on over to our comprehensive step-by-step guide.


  1. Calculate Gross Pay.
    1. For hourly employees, simply multiply their hourly rate by the number of hours worked during the pay period. Remember to increase the rate for any overtime hours worked.
    2. For salaried employees, take their annual salary and divide it by the number of pay periods.
    3. Bonuses, commissions, or tips also get added to gross pay.
  2. Subtract Pre-Tax Deductions. If your employees have any pre-tax deductions like 401(k), for example, subtract them from gross pay so that their taxable income is reduced by this amount.
  3. Calculate the Federal Income Tax. Now that you have adjusted gross pay, you can calculate the amount of federal income tax that your employees owe the IRS. The tax rate ranges from 0% all the way up to 37%. We won’t get into the nitty-gritty here, but you can find all the minute details in the IRS Publication 15-T.
  4. Deduct FICA Taxes. FICA stands for Federal Insurance Contributions Act, and it collects two taxes that both employees and employers have to pay: Social Security and Medicare.
    1. Social Security Tax: Withhold 6.2% of each employee’s taxable wages up to $142,800 for the year. Any salary above $142,800 is exempt. As an employer, you also have to match this tax and pay the IRS 6.2% of your employee’s salary dollar-for-dollar.
    2. Medicare Tax: Withhold 1.45% of each employee’s taxable wages up to $200,000 for the year. If an employee makes more than $200,000, an Additional Medicare Tax (super original, right?) of 0.9% should be withheld. As an employer, you’re only responsible for matching 1.45% of the first $200,000, so you don’t have to worry about paying the Additional Medicare Tax that your high wage employees have to pay.
  5. Calculate the FUTA Tax. FUTA stands for the Federal Unemployment Tax Act. Employers are responsible for paying 6% of each employee’s first $7,000 of taxable income. Employees are not responsible for paying FUTA. Note that if you pay state unemployment tax in full and on time, you are eligible to receive a 5.4% tax credit, bringing your effective FUTA tax rate down to 0.6%. Be sure to take advantage of this easy credit!
  6. Subtract Post-Tax Deductions. Many of your employees won’t have post-tax deductions, which can be anything from garnishments like child support to life insurance. But for the ones that do, you will need to make a deduction here and send the deduction to the appropriate jurisdiction.

Mississippi State Payroll Taxes

Mississippi’s state income tax is fairly straightforward. There are just three income tax brackets, and the tax rates range from 3% to 5%. Employees who earn more than $10,000 a year will hit the top bracket.


No cities within Mississippi charge any additional municipal income taxes, so it’s pretty simple to calculate this part of your employees’ withholding.


Mississippi State Unemployment Insurance (SUI)

As an employer, you’re responsible for paying SUI (remember, if you pay your state unemployment tax in full and on time, you get a 90% tax credit on FUTA).


Mississippi’s SUI rates range from 0% to 5.4%. The taxable wage base in 2020 is $14,000 for each employee.


If you are a new small business owner (congratulations, by the way!), you’ll pay 1% the first year.


Now Prep Your Signature!

That’s all right when payroll taxes are right! Calculate each employee’s net pay, cut those checks (or transfer those direct deposits, whatever suits your employees’ fancy), and make sure you have enough left in your own account to cover FICA and unemployment taxes.


Be sure to submit your federal tax filings by filling out Forms 940 (yearly) and 941 (quarterly). Deposits can also be made on an ongoing basis through the EFTPS payment system. Learn more about the IRS deadlines here.
