Payroll tax in Oklahoma: What employers need to know [2026]
In this article
Dealing with taxes can be a headache, no matter how prepared you are. As a business owner in Oklahoma, you have to navigate both federal and state payroll tax laws — on top of the Federal Insurance Contributions Act (FICA) requirements like Social Security and Medicare taxes, there are also state payroll taxes that you’ll need to consider.
Oklahoma has a progressive tax system. This means your employees’ tax rates increase with their income, leading to higher tax liability. If your business grows and you hire more people, your employer tax contributions and deductions will also increase.
Managing a remote workforce or a small business in Oklahoma? It’s crucial to understand your state tax obligations. We’ll guide you through the different tax types, their rates, who they apply to, how to pay them, and more.
The 2 Oklahoma payroll taxes
The Oklahoma Tax Commission administers the state’s payroll taxes. Oklahoma has two types of payroll taxes you need to be aware of: unemployment insurance and income tax.
Employers must withhold taxes from the paychecks of Oklahoma resident and nonresident employees who work in the state. As per state laws, new hires must be reported to the Oklahoma Employer New Hire Reporting System within 20 days of their hiring date, to ensure they’re accounted for during payroll tax withholdings.
Unemployment insurance tax
In Oklahoma, employers must pay state unemployment insurance tax to provide financial support to workers who lose their jobs due to external factors. This tax is paid to the Oklahoma Employment Security Commission (OESC), which handles the state unemployment tax to fund the Oklahoma Unemployment Insurance (UI) Trust Fund.
Under the Federal Unemployment Tax Act (FUTA), Oklahoma employers must pay both the federal and state unemployment tax. Employers withhold 6% on the first $7,000 of an employee’s wages for FUTA. According to the IRS, employers may qualify for a 5.4% tax credit on federal unemployment contributions.
Note that the new employer tax rate differs from established businesses in the table below.
Who pays | Employer |
|---|---|
Tax rate | New businesses: 1.5%. Established businesses: 0.3% to 9.2% |
Taxable wage base | Up to $25,700 |
State income tax
Employers in Oklahoma must deduct state income tax from their employees’ wages and remit it to the Oklahoma Tax Commission’s withholding tax division. This applies to all employers who pay wages that are subject to state income tax withholding, whether the employee is a resident or nonresident of the state. New employers can fill out form OK-W-4 to start paying taxes.
It’s the employer’s responsibility to stay up to date with Oklahoma state tax rates, laws, and tables to ensure accurate employee withholdings and take-home pay.
Who pays | Employee |
|---|---|
Tax rate | 0.25% to 4.75% |
Taxable wage limit | No limit |
Maximum tax | No maximum |

Payroll tax due dates in Oklahoma
Keeping up with payroll taxes and due dates is vital for every business. Like many other states, Oklahoma has strict deadlines for payroll tax submissions, and non-compliance may result in penalties.
Oklahoma unemployment insurance taxes are due to the Oklahoma Employment Security Commission on a quarterly basis:
First quarter (January-March): Due April 30
Second quarter (April-June): Due July 31
Third quarter (July-September): Due October 31
Fourth quarter (October-December): Due January 31
Employers must file their income tax withholding returns every quarter and submit payments to the Oklahoma Tax Commission (OTC). The income tax withholding schedules provide a graduated tax rate employers must deduct from their employees’ gross pay for each pay period. The payment deadlines are as follows:
If the company withholds less than $500 per quarter, payments are due on the 20th of the month following the close of the quarter
If the company withholds more than $500 per quarter, payments are due on the 20th of the following month
If the company withholds $10,000 per month or more, payments are due on the 20th and 30th of each month
For the quarterly schedule, if the due date falls on Saturday, Sunday, or a legal holiday, the due date is the next banking day.
