How sales tax works in Colorado
Colorado has the lowest state rate of any state that levies one, at 2.9%, but home-rule cities set their own rates and rules, so the combined rate commonly lands between 7% and 9%. Denver, for example, is around 8.81%.
Rates are approximate and current as of the 2024–2025 tax years. Local rates change and vary by address; confirm the exact figure with the Colorado department of revenue or a rate lookup by ZIP code before relying on it.
