Colorado Sales Tax Calculator 2026 – how it works
Colorado sales and use tax is flat-rate based at the state level. The statewide component is the Colorado state sales tax at 2.90%. Under state law, additional local sales and use taxes may be imposed by cities, counties, and special districts, which can affect the overall rate that applies to a transaction. A sales tax estimate typically reflects the combined effect of the statewide rate and any applicable local components, depending on where the transaction is sourced and which local jurisdictions apply.
Examples
A simplified estimate can be illustrated using the statewide component alone. If a transaction is subject only to the Colorado state sales tax at 2.90%, the estimated tax is calculated by applying 2.90% to the taxable amount. In practice, the total sales and use tax rate may differ when city, county, or special district sales and use taxes apply under state law. Because local rates are not specified here, examples are limited to the statewide component and do not represent a complete combined rate.
Limitations and important notes

This content includes the Colorado state sales tax at 2.90% and acknowledges that cities, counties, and special districts may impose additional local sales and use taxes under state law, but it does not include any specific local rates. The applicable combined rate can vary by location and jurisdictional rules.
