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 1.375 percent countywide. The floor of 6.1 percent is unincorporated county where Marion County Ambulance District also applies. The ceiling of 10.35 percent is at Hannibal, on top of Marion County Ambulance District and SCZ Development District Inc CID. That ceiling comes from a community improvement district, which in Missouri can cover a single shopping center or one development rather than a whole city, so most addresses pay less. 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.
