Why the rate here is not the whole story
Missouri charges 4.225 percent statewide and then stacks a county rate, city rates and special district rates whose boundaries do not follow county lines, so a single rate for the whole county does not exist. The county itself levies 1.875 percent countywide. The floor of 6.1 percent is state plus county in unincorporated areas with no city and no district. The ceiling of 9.975 percent is at Hermann, on top of Hermann Area Ambulance District. Missouri's address level rate map is required by RSMo 32.310 and is operated for the Department of Revenue on a vendor domain, which is the map dor.mo.gov itself links.
How do I find the exact rate for an address in Gasconade County?
Use Missouri's own address lookup, which the state designates and an outside provider runs for it. In Gasconade County the rate depends on the address, anywhere from 6.1% to 9.975%.
