How Oklahoma Sales Tax Works
Sales tax in Oklahoma is collected at the point of sale on most tangible goods and some services. The state portion of 4.5% is uniform statewide, while local jurisdictions may add their own rates, averaging 4.56% across the state. Certain items like groceries and prescription medications may be exempt or taxed at reduced rates.
When budgeting in Oklahoma, remember that sales tax affects your purchasing power. With a median home value of $178,300 and a property tax rate of 0.87%, understanding all taxes helps you make informed financial decisions.
What Is and Is Not Taxed in Oklahoma
Unprepared groceries are exempt from Oklahoma state sales tax — the state grocery tax ended August 29, 2024; local sales taxes still apply.
Prescription medicines are exempt in Oklahoma, as they are in every state that levies a sales tax; over-the-counter drugs and most medical supplies are treated separately and are frequently taxable.
Out-of-state sellers must register and collect Oklahoma tax once they cross the state's economic nexus threshold, a rule that follows from the 2018 Supreme Court decision in South Dakota v. Wayfair. Below that threshold, the buyer technically owes use tax instead.
