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 1.6875 percent countywide. The floor of 5.9125 percent is state plus county in unincorporated areas with no city and no district. The ceiling of 9.1625 percent is at Kennett. 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 Dunklin County?
Use Missouri's own address lookup, which the state designates and an outside provider runs for it. In Dunklin County the rate depends on the address, anywhere from 5.9125% to 9.1625%.
