Oklahoma has one state sales tax rate, and almost every purchase is taxed again at a city or county rate that depends on where the sale happens. The grocery rule is the part most shoppers get wrong: the state dropped its tax on food in 2024, yet the checkout total still includes local tax.
This guide sets out the state rate, what the Oklahoma Tax Commission says about groceries and prepared food, how local rates are added, who owes use tax on online purchases, how cars fit in, and what changed in 2026, using the Commission's own pages and rate chart read on 2 November 2026.
The Oklahoma Tax Commission states that sales tax is levied at 4.5% of the gross receipts from the sale or rental of tangible personal property and from the furnishing of specific services. Sales tax also applies to certain services provided in the state, so a service is not automatically exempt just because nothing physical is handed over.
If the sale takes place in a county or municipality that levies its own sales tax, the Commission says those taxes are applied as well. For goods that are delivered, the rate that applies is the one at the point of delivery, not the seller's address.
The Commission identifies HB 1955, known as the grocery tax bill, as the law that cut the state sales tax rate on food and food ingredients to 0%. Businesses had to comply from 29 August 2024, with no grace period. Two limits matter at the till:
| Exempt from the state tax (examples from the Commission) | Still taxed at 4.5% state (examples from the Commission) |
|---|---|
| Milk, soft drinks in a bottle or can, baby food, fruits and vegetables, potato chips, fish and meats, herbs and spices, frozen meals, pasta, flour | Alcoholic beverages, beer, dietary supplements, self-serve fountain drinks, rotisserie chicken, pet food, vitamins, toiletries, over-the-counter medications, food made by the seller such as birthday cakes, sushi, sandwiches, deli and salad |
The Commission defines prepared food as food intended for, and generally ready for, immediate consumption, where the seller does something more than sell it: heat it, mix it or provide utensils. Food bought at a restaurant counts as prepared food and carries state tax plus any local tax. The Commission also lists exceptions: for example, food that must be cooked after the sale, or unheated food sold by weight or volume as a single item with no utensils from the seller, can be exempt from state tax. Its product guide and flow chart list item-by-item treatment for borderline cases.
Our own calculation, using the October to December 2026 rates from the Commission's rate chart (updated 11 August 2026). The city and county rates below are the figures the chart lists for these two places; the $250 basket is our assumption. The Commission says the city tax, county tax and state tax are added together.
| Place | Local rate (city + county) | Combined rate with 4.5% state | Tax on $250 of groceries (local only) | Tax on $250 of prepared food (state + local) |
|---|---|---|---|---|
| Oklahoma City (COPO 5521) | 4.125% | 8.625% | $10.31 | $21.56 |
| Tulsa, in Tulsa County (COPO 7281) | 4.017% | 8.517% | $10.04 | $21.29 |
The Tulsa line assumes a sale in the part of Tulsa that lies in Tulsa County, where the chart adds a 0.367% county rate; other parts of the city sit in other counties. Oklahoma City also extends into Canadian, Cleveland and Pottawatomie counties, where the chart marks the city rate as having a county tax added on top, so the Oklahoma City line applies to the part of the city in Oklahoma County. Real receipts are rounded to the cent by the retailer. Local rates change, so treat this as an illustration of the method, not a quote for your address.
The Commission publishes a quarterly rate chart and a Sales and Use Tax Rate Locator with a database download. The chart read for this guide is headed "Rates Effective October through December 2026" and was updated 11 August 2026. Rates do change between quarters: the same chart lists Salina moving from 4% to 5% on 1 October 2026.
Where county and municipal boundaries overlap within a ZIP+4 area, the Commission says the statute applies the lowest rate in the area. Because the rate depends on the delivery or sale address, use the Commission's locator rather than a statewide average.
Use tax is the companion to sales tax. The Commission says it must be paid on tangible personal property purchased and brought into the state for storage, use or consumption, and that the county or municipal use tax also applies where the property is brought into a place that levies one. The rate chart notes that local use tax is due at the same rate as the local sales tax, in addition to the 4.5% state rate.
Retailers that sell into Oklahoma are required to collect state and local use tax from the customer, and the Commission's infographic puts the remote-seller collection threshold at $100,000 of taxable sales. When a seller does not collect, individuals can pay use tax themselves: the Commission says use tax can be paid through its OkTAP portal or noted and paid on the Oklahoma 511 income tax return.
Our example: an untaxed $200 online purchase delivered to Oklahoma City at the chart rates above (8.625% combined) would owe $17.25 in use tax. This assumes the item is taxable and no tax was paid to another state.
Cars are not taxed like ordinary goods. The Commission's sales and use tax rule says that sales of motor vehicles on which the Oklahoma vehicle excise tax (Title 68, Section 2101 and following) has been or will be paid are subject to sales and use tax at 1.25% of the gross receipts. The same rule's vehicle-sales section (710:65-19-215) adds that these vehicle sales are not subject to local sales tax. The excise tax itself is a separate tax. This page does not state the excise rate or how it is calculated, because we did not read a current official source for it; check the vehicle titling authority before buying. The rule text we read is the 2022 edition of the Commission's chapter 710:65, so confirm it has not been amended.
The Commission's 2026 legislative summary lists three sales and use tax items. None of them is described there as changing the 4.5% state rate.
The federal government stopped producing the penny in November 2025. The Commission says retailers must still calculate Oklahoma sales tax on the sales price before any cash rounding, so rounding to the nearest nickel does not change the tax. Its example: a $25.50 item at a 9.50% combined rate has $2.42 of tax, whatever the cash rounding.
