What is the sales tax rate in Oklahoma?

The sales tax rate in Oklahoma is composed of a state sales tax rate and additional local sales tax rates that are determined by the county or city in which the business operates or the sale occurs. 

The state sales tax rate in Oklahoma is 4.5%. However, local tax jurisdictions (cities and counties) may levy additional sales taxes, which can vary significantly. As a result, the combined sales tax rate in Oklahoma can range from 4.5% to over 11% in some areas.

When calculating sales tax, businesses should consider both the state sales tax rate and any applicable local rates. For example, if a business operates in a city with a local tax rate of 2%, the combined sales tax rate would be 6.5% (state tax rate of 4.5% + local tax rate of 2%).

As local sales tax rates are subject to change, it is essential to verify the current rates with the Oklahoma Tax Commission or through a reliable sales tax software solution.

If your business has a physical presence (also known as a nexus) in Oklahoma or meets the economic nexus threshold, you are required to collect sales tax from customers on taxable transactions. 

In Oklahoma, sales tax is primarily levied on tangible personal property and certain services. So generally, if your business sells tangible goods or provides taxable services in Oklahoma, you are required to collect and remit sales tax.

The Oklahoma Tax Commission provides a list of taxable services, which includes services such as telecommunication services, installation, repair, and maintenance of tangible personal property, among others.

Keep in mind that sales tax exemptions may apply to specific transactions or customers. For example, sales to government entities, non-profit organizations, and certain agricultural products may be exempt from sales tax. It’s essential to verify any exemptions with the Oklahoma Tax Commission.

Sales Tax Physical Nexus checklist for Oklahoma

Here’s a checklist to help you determine if your business has a physical sales tax nexus in Oklahoma:

  • Do you store inventory or goods in Oklahoma, including using a third-party fulfillment center or warehouse?
  • Do you have employees, contractors, or agents working in Oklahoma?
  • Have you attended trade shows, fairs, or events in Oklahoma where sales occurred?

So if you answered “yes” to any of these questions, your business likely has a physical nexus in Oklahoma and is required to collect and remit sales tax.

Oklahoma Economic Nexus Threshold: Revenue, Thresholds and Transactions

Economic nexus is a concept that allows a state to require out-of-state businesses to collect and remit sales tax based on their sales volume or transaction count, rather than physical presence. 

In Oklahoma, the economic nexus threshold is set at $100,000 in annual gross revenue from sales into the state. This includes both taxable and nontaxable sales. If your business surpasses this threshold, you will have economic nexus in Oklahoma and are required to collect and remit sales tax on sales made to customers in the state.

Which services are taxable in Oklahoma?

Oklahoma applies sales tax to a wide range of services, including some that are not commonly taxed in other states. Taxable services in Oklahoma include:

  • Telecommunications services
  • Installation, maintenance, and repair of tangible personal property
  • Computer services
  • Rental or lease of tangible personal property
  • Admission fees to places of amusement, sports, and recreation

Keep in mind that some services are exempt from sales tax, such as professional services (e.g., legal, accounting, medical) as well as certain labor services. So it’s important to consult with the Oklahoma Tax Commission to determine the taxability of your business’s services. 

Oklahoma Sales Tax on Products: How to Calculate What Your Business Should be Charging

To calculate sales tax on products in Oklahoma, follow these steps:

  • Determine the taxable base: Include the cost of the product, any shipping or handling charges, and any additional fees or charges associated with the sale.
  • Identify the applicable tax rate: Find the combined state and local sales tax rate for the location where the product is delivered or where the sale takes place.
  • Calculate the tax amount: Multiply the taxable base by the applicable tax rate.

Example: If you sell a product for $100, with a $10 shipping charge, and the combined sales tax rate is 8.5%, the total tax due would be $9.35 [(100 + 10) * 0.085].
