What is Colorado Sales Tax Calculator?
Colorado Sales Tax Calculator — The Colorado sales tax is a consumption tax of 2.9% levied by the state on retail purchases, with local jurisdictions adding up to roughly 7.1% more (maximum combined 10%).
This page calculates Colorado sales tax with the same rate table the main calculator uses: 2.9% state base rate, plus local rates that can add up to roughly 7.1% depending on the city and county — a maximum combined rate of 10%. The table below precomputes common purchase amounts at both the state-only and maximum combined rates; the calculator handles any amount, including reverse calculations ("price included tax — how much was the tax?").
