Oklahoma payroll tax and registration guide

Why is this important?

To maintain compliance with state payroll tax regulations, you must provide the following information before you can use OnPay to run payroll:

• State Employer Identification Number and state/local tax IDs
• Tax rates - State tax offices set these rates based on the type, age, and size of your business
• TPA and power of attorney - Most tax offices require this before we can submit quarterly wage reports and deposits on your behalf

This information must be provided and maintained by you in order for OnPay to accurately file and deposit tax payments for your company. OnPay is not responsible for any penalties or interest that incur due to missing or incorrect company tax information.

Each state has its own requirements, so if you pay employees in more than one state, you’ll find separate tax guides for each state.

See what information you need to provide OnPay, and what taxes and filings OnPay handles for Oklahoma Employers.

• Information OnPay needs from you

  Use this checklist to make sure you’ve covered everything required to set up your account as an Oklahoma employer, so OnPay can accurately file and pay taxes on your behalf:

Where you can find the tax account numbers you need

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.
