Get your real Colorado total — state tax is only 2.9%, but city, county, and special district rates can push your combined total well past 8%.

Colorado Has One of the Lowest State Rates — and One of the Widest Local Ranges

Colorado's state sales tax on vehicles is just 2.9%, among the lowest base rates in the country. But that headline number is misleading on its own, because Colorado layers city, county, and special district taxes (like RTD transit taxes in the Denver metro) on top — and those local rates vary more than almost anywhere else.

In the Denver metro area, local add-ons bring the combined rate to roughly 7.9%. Rural counties with no city or special district taxes can land close to the 2.9% state floor. Mountain resort towns, which often carry additional local district taxes for tourism infrastructure, can push combined rates toward 8–9%.

Because the gap between low-tax Colorado and high-tax Colorado is so large, it's worth checking your specific city and county's combined rate on the Colorado Department of Revenue's site before you commit to a price — the swing can be worth several hundred dollars on a typical purchase.

Frequently Asked Questions

What is the car sales tax in Colorado?

Colorado's state sales tax on vehicles is 2.9% — one of the lowest base rates in the country. Local cities, counties, and special districts add their own rates on top, and combined totals typically range from about 3% in low-tax rural areas to 8–9% in the Denver metro and mountain resort towns.

Why is Colorado's combined tax rate so hard to pin down?

Colorado allows overlapping city, county, and special district taxes (like RTD transit tax in Denver), so the total varies block by block in some areas. There's no single Colorado rate — always check the specific jurisdiction where you'll register the vehicle.

Does Colorado tax trade-ins?

Yes. Your trade-in value reduces the taxable purchase price before both the state and local portions of tax are calculated, lowering your total tax bill proportionally at whatever combined rate applies in your area.

How much is Colorado vehicle registration?

Colorado registration is value-based and typically starts around $75 for a mid-range vehicle, decreasing in future years as the vehicle's assessed value depreciates. Plates are included in the registration fee.

Is there a doc fee cap in Colorado?

No. Colorado does not cap dealer documentation fees by statute, so amounts vary by dealer. Always ask what the fee includes and whether there's room to negotiate it down.
