Colorado offers a mix of state and local sales taxes that impact vehicle purchases and registrations. While the statewide sales tax rate is relatively low, local jurisdictions can add their own taxes, increasing the total amount you’ll pay when buying or registering a vehicle.
This guide explains how Colorado’s vehicle sales tax system works, highlights local tax variations, and shares practical ways to help you save thousands on your next vehicle transaction.
Colorado Vehicle Sales Tax Overview
The Colorado state sales tax rate is 2.9%, which applies to most vehicle sales and leases. However, local governments—counties, cities, and special districts—can impose additional sales taxes that significantly increase the total rate.

How Vehicle Sales Tax Is Calculated in Colorado
Sales tax on vehicles is generally calculated on the purchase price paid to the dealer or private party. When purchasing from a private seller, the tax is due based on the sales price or fair market value of the vehicle.
In addition to sales tax, Colorado charges other vehicle-related fees at registration, but these are separate from the sales tax calculation.
