Oklahoma payroll tax and registration guide

Updated September 19, 2023

This article will cover:

• What information OnPay needs from you
• What state and local taxes and filings OnPay handles for Oklahoma employers
• Where you can find the tax account numbers needed
• Paying employees in other states?

Why is this important?

The following information requests and registration instructions are required before you can use a payroll provider to run payroll. This is in compliance with state payroll tax regulations. Without this information, OnPay is unable to file or deposit any tax payments for your company, and will not be responsible for any resulting penalties or interest. Note: If this isn't the only state where you have employees, there will be a separate guide like this one for each state where you hire and pay workers.

What information OnPay needs from you

What state and local taxes and filings OnPay handles for Oklahoma employers

Where you can find the tax account numbers needed

If you are an existing employer who has previously run payroll in Oklahoma, you likely already have the IDs and online accounts needed for OnPay to process your tax filings. 

If you are a new employer in Oklahoma, you will need to register your business with the Oklahoma Tax Commission and the Oklahoma Employment Security Commission. This must be completed for OnPay to be able to file and pay your Oklahoma taxes.

Withholding Tax Account Number

Existing Oklahoma Employer: 

• You can find your Account ID on notices received from the Oklahoma Tax Commission.

New Oklahoma Employer: Register with the Oklahoma Tax Commission 

• Click here to register your business
• Select “Register for a Business” and follow the prompts
• You should receive your Account ID and deposit schedule one day after registering online, 2 weeks if registering by mail, or the same day if registering in person.
• You will need to register with this department if you have employees who both live and work in Oklahoma or for any employees who calculate Oklahoma withholding taxes regardless of where they live/work. If your business is located outside of Oklahoma, but your employees work or live in Oklahoma you will likely need to register with this agency.

Unemployment Account Number and Tax Rate

Existing Oklahoma Employer: 

• Existing employers can find the Unemployment Account Number on the following forms:
• Your Unemployment Tax Rate can also be found on the notice of the employer's contribution rate. Employer contribution rates range from 0.3% to 9.2% for SUTA, with a wage base of $25,700.

New Oklahoma Employer: Register with the Oklahoma Employment Security Commission (405) 557-7100

• Register your business with the OESC.
• Click “Create an Employer Account” and follow the prompts.
• You should receive your number and tax rate in 2-3 weeks after registering online.
• You will need to register with this department if you have employees that work in Oklahoma. If your business is located out of the state, but some of your employee's primary work location is in Oklahoma, you will likely need to register with this agency.
• New employers generally have a rate of 1.5% for SUTA, with a wage base of $25,700.

Paying employees in other states?

If you operate in multiple states or just have employees working from home across a state line, it's important to file the correct state forms for those workers. See what forms we file in the states where you pay employees.
