A clear, up-to-date overview of Oklahoma’s sales tax rates, rules, and compliance requirements for businesses.
Oklahoma has a statewide base sales tax rate of 4.5%. On top of this, local jurisdictions like cities, counties, and special districts can impose their own sales tax. Combined local taxes can add as much as 7% to the total sales tax rate.
So when state and local rates are combined, sales tax rates across Oklahoma range from 4.5% (in areas with no local taxes) to 11.5% (in areas with the maximum additional local taxes). Businesses that make taxable sales in Oklahoma must collect both state and applicable local sales taxes.
The Oklahoma Tax Commission administers sales tax in the state. Sellers who reach $100,000 in annual sales in Oklahoma are considered to have economic nexus and must collect and remit tax. The commission offers resources online and over the phone to help businesses comply.
To calculate Oklahoma sales tax, multiply the purchase price by the combined state and local tax rate(s) for that jurisdiction. For example, in the city of Tulsa, three tax rates apply: the state tax (4.5%), a city tax (3.65%), and a county tax (0.367%). The combined sales tax rate in the city of Tulsa is, therefore, 8.517%. So if a taxable item costs $100, a Tulsa customer would pay a sales tax of $8.52 (8.517% rounded up to the nearest cent).
Penalties for failing to pay Oklahoma sales tax can include fines of up to 10% of the unpaid taxes plus interest charges of 1.25% per month. Criminal charges may also apply for willful violations.
In destination-based sales tax states like Oklahoma, the sales tax rate is determined based on the address of the buyer. In origin-based states, sales tax is based on the seller's location.
