Sales Tax Calculator — Colorado
Colorado's 2.9% statewide rate is the lowest of any state that taxes sales, but dozens of home-rule cities administer and collect their own taxes, so the average combined rate reaches 7.89%. Denver and many municipalities self-collect, making local compliance unusually fragmented.

Colorado's statewide base rate is 2.9% and its average combined state + local rate is 7.89% (pre-filled). The rate is editable because local rates vary by exact address and some items are exempt or taxed differently. Statewide rates are from the Tax Foundation, 2026. An estimate, not tax advice.
