How This Calculator Works

Oklahoma general sales/use tax starts with the 4.50%state rate. The calculator then adds county and city/town rates from the OTC COPO chart or rate locator.

COPO markers matter. A city row marked ** means county tax is also due, and # means local use tax is due for out-of-state sales at the same local rate. Grocery mode removes only the state portion for qualifying food; local tax still applies.
