Why the rate here is not the whole story
Oklahoma charges 4.5 percent statewide and then stacks a county rate and a city rate, and city boundaries do not follow county lines, so a single rate for the whole county does not exist. The county itself levies 1.7 percent countywide, and that county rate applies inside its towns as well as outside them. The floor of 6.2 percent is state plus county in the unincorporated part of the county. The ceiling of 10.95 percent is at West Siloam Springs. Oklahoma dropped the state 4.5 percent from food and food ingredients on August 29 2024, but every local rate still applies to groceries, so the figures here are the general merchandise rates.
