This is the state rate plus the population-weighted average local rate. Your actual rate depends on the specific address — city and special-district taxes vary within every state. Before collecting tax from customers, verify the exact rate for the delivery address with the state’s Department of Revenue or an address-level lookup.
About this rate
Sales tax in Colorado, explained
In Colorado, local taxes do most of the work. The state rate is only 2.90%, but counties and cities add about 4.99% on average, for a combined 7.89% — roughly in the middle of the pack (16th of 51 by combined rate). Because so much of the rate is local, it swings widely by location: Denver and Colorado Springs set their own, and the statewide maximum reaches roughly 9.10%.
For context, the highest combined rate in the country is Louisiana's 10.13%, and five states charge no sales tax at all — so Colorado's 7.89% sits toward the higher end. Just remember the figure here is a state average: the rate in Denver very likely differs from the rate two towns over. If you are collecting sales tax from customers, confirm the exact rate for each delivery address with the Colorado Department of Revenue before you rely on it.
Compare with states at a similar rate: New Mexico (7.68%), Minnesota (8.14%), Texas (8.20%). Or see all 50 states and DC.
