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 8.9 percent is at Hayden.
How do I find the exact rate for an address in Routt County?
