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 Oklahoma employers

First things first, we have to pay the federal government. Whether your employees are hourly or on salary, all federal taxes remain the same. We’ll go over the general breakdown here, but if you want more details, hop on over to our step-by-step guide.

  • First, calculate gross wages. If your employee is being paid hourly, simply multiply the number of hours worked during the pay period by the hourly rate. For salaried employees, take their annual salary and divide it by the number of pay periods. Don’t forget about bonuses, commissions, and tips. They all go into gross wages.
  • Then, deduct pre-tax withholdings. Some of your employees might choose to participate in 401(k), HSA, FSA, or other eligible benefits. They are subtracted from gross wages before income taxes are taken out.
  • Deduct out Federal income taxes. The big enchilada. It’s the largest tax that your employees will pay. The tax rates vary based on income and can range from 0% all the way up to 37%. Click here to read all you need to know about deducting the right amount of federal income taxes.
  • Deduct FICA taxes. FICA stands for Federal Insurance Contributions Act, and it was first introduced all the way back in 1935. There are 2 FICA taxes. The first is Social Security tax, which is 6.2% of the first $168,600 of taxable wages per year. Any wages above $168,600 is not taxed. As the employer, you also have to pay this tax. You have to match your employees’ contributions dollar-for-dollar. The second is Medicare tax, which is 1.45% of the first $200,000 of taxable wages per year. After that, the rate jumps up to 2.35%. The 0.9% bump is called the Additional Medicare Tax (obviously). As the employer, you must match the first 1.45% of your employees’ contributions, but you’re exempt from the Additional Medicare Tax.
  • Pay FUTA taxes. Your employees get to sit this one out. Only employers are responsible for paying federal unemployment taxes, which are 6% of the first $7,000 of each employee’s taxable income for the year. However, there’s one huge caveat that can reduce your FUTA tax liabilities by a whopping 90%. If you pay your taxes in full and on time each quarter, you are eligible for a tax credit of up to 5.4%. But it all depends on which state you do your business in. You can refer to this IRS guidance for more details.
  • Finally, deduct post-tax withholdings. After you’ve deducted all the proper taxes, there’s just one more thing you have to look out for. Some of your employees may be levied wage garnishments or child support, so watch out for a letter from the court that may show up at your office.

Oklahoma state payroll taxes for 2024

With six marginal tax brackets based upon taxable income, payroll taxes in Oklahoma are progressive. Tax rates range from 0.25% to 4.75%. Single filers will pay the top rate after earning $7,200 in taxable income per year. The good news is that only the state charges income tax, so there’s no need to worry about local taxes.

Oklahoma state unemployment insurance (SUI)

Oklahoma has a State Unemployment Insurance (SUI), and contribution rates range from 0.3% to 9.2%. In 2024 the wage base for SUI is $27,000 of each employee’s taxable income. In 2023, it was $25,700. If you’re a new employer (congratulations, by the way!), your rate will be 1.5%.


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 Oklahoma workers’ comp insurance.

Write those paychecks

Now that you’ve figured out payroll taxes and withholdings, it’s time to cut those checks. Just make sure you keep your portion of the FICA and FUTA payments in mind. Those taxes can add up come tax season if you don’t remit them regularly. And you definitely want that FUTA tax credit, don’t you? All federal tax filings are due quarterly. Employers must complete the IRS Form 941 along with paying the payroll taxes. FUTA unemployment taxes must also be paid quarterly, but you only have the fill out the IRS Form 940 at the end of the year. Or, if you’d rather pay on an ongoing basis, you can use the EFTPS payment system. All the employment tax filing due dates can be found here.

More calculators Oklahoma employers can try

The Oklahoma payroll calculator at the top of this page can be used to quickly calculate an employee’s gross pay, net pay, and deductions in a few clicks. But sometimes an employer needs to do a little more math before they can cut their employees’ paychecks. For example, do you own a business where employees get tips from customers? Keep in mind that you are responsible for withholding taxes from your employees’ paychecks based on the tips they receive. Additionally, if an employee leaves for another employer, you’ll need to calculate their final pay. So, if you need a little more help with the number-crunching, check out some of the calculators below.
