What's in the Oklahoma rate file
Oklahoma data ships inside every edition — we do not sell single-state files. Each row carries the ZIP code, county and city name, the rate at each jurisdiction level, the combined total, and whether shipping is taxable. The higher editions add district reporting codes, FIPS codes, effective dates and sales tax holiday windows.

How local tax works in Oklahoma. State-collected. City and county taxes are levied by local ordinance but administered through the Tax Commission, identified by a four-digit city or county code on the return.
Worth knowing. Reporting is done by jurisdiction code against quarterly rate charts, also published as CSV and Excel. Since 2024 groceries are exempt from the state rate but cities and counties may still tax them, so the state and local bases diverge.
Questions
Oklahoma sales tax questions
What is the sales tax rate in Oklahoma?
The statewide base rate is 4.5%. Local jurisdictions add their own rate on top, so the rate you must actually charge is almost never the state rate.
Is shipping taxable in Oklahoma?
Generally no. In Oklahoma a delivery charge is not taxable, and combining it with handling does not make it taxable.
That distinction catches people out, which is why our file carries both flags — TAX_SHIPPING_ALONE and TAX_SHIPPING_AND_HANDLING_TOGETHER — on every row, for the specific jurisdiction. Your system doesn't have to encode the rule.
How many sales tax jurisdictions are there in Oklahoma?
We track 636 bodies that actually levy a sales tax in Oklahoma — 76 counties, 559 cities and 1 special districts — across 764 OK ZIP codes. We count a county, city or district only where it charges something, not merely because it appears in the file.
