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 1 percent countywide. The floor of 3.9 percent is state plus county in unincorporated areas with no city and no district. The ceiling of 9.9 percent is at Mt Crested Butte, on top of a rural transportation authority. 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.
How do I find the exact rate for an address in Gunnison County?
Use Colorado's own address lookup. In Gunnison County the rate depends on the address, anywhere from 3.9% to 9.9%.
