Oklahoma Sales Tax Calculator
Figure the tax, the total, or the pre-tax price for any U.S. state or city rate
Oklahoma levies a 4.5% state sales tax on most retail purchases, but when you factor in county and municipal taxes, shoppers typically pay more. The average combined state and local sales tax rate in Oklahoma is 8.99%, one of the highest combined rates in the country and the sixth-highest nationally according to the Tax Foundation's 2025 data.
Local jurisdictions — cities, counties, and special districts — add their own rates on top of the state base. Across Oklahoma's 77 counties and hundreds of municipalities, local add-ons range from less than 1% to over 7%, pushing the total as high as 11.5% in some areas.
Groceries get partial relief. Starting August 29, 2024, Oklahoma eliminated the state-level sales tax on food and food ingredients (HB 1955). That means the 4.5% state rate no longer applies to items like bread, produce, and packaged foods. However, local taxes — city and county — still apply to groceries, so shoppers will still pay something at the checkout.
Worked example: If you buy a $100 appliance in a city with the average combined rate of 8.99%, you will pay $8.99 in sales tax for a total of $108.99. In a higher-rate city at 11%, that same appliance costs $111. Use the calculator above to enter the exact rate for your location and get a precise total.
Practical example — Oklahoma
A $500 electronics purchase in a location with Oklahoma's average 8.99% combined rate adds $44.95 in sales tax, bringing the total to $544.95.
