Colorado state guide
Colorado sales tax
Colorado applies 2.9% state sales tax plus applicable city, county and special-district taxes. A qualifying vehicle trade-in reduces taxable purchase price, while manufacturer rebates do not.
Title and registration
Colorado registration and specific ownership tax depend on original taxable value, vehicle age, weight and county, so the calculator treats final registration as an external/manual estimate.
Worked example
A $30,000 vehicle with a $5,000 qualifying trade-in has a $25,000 taxable amount before state and local rates are applied.
