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. Denver is a consolidated city and county, so the 5.15 percent the state table shows as a city rate is the levy that covers the whole county. Every location code the state publishes inside this county carries the same 9.15 percent total. That total 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.
