Why the rate here is not the whole story
Colorado charges 2.9 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 0.25 percent countywide. The floor of 3.25 percent is unincorporated county where the Scientific and Cultural Facilities District also applies. The ceiling of 8.05 percent is at Englewood, on top of the Regional Transportation District and the Scientific and Cultural Facilities District. That ceiling is set by a self collected home rule jurisdiction, which administers its own sales tax and can change it on a date the state file does not carry, so confirm it with the jurisdiction or the state lookup before charging it.
