Quick answer

Buying a car in Colorado comes with two big costs. Sales tax is paid once: 2.9% state plus local taxes, for a total of about 7.5% to 9.2% in the Denver area, based on where you register. Registration is paid every year and is driven mostly by specific ownership tax: 2.1% of 85% of the original MSRP in year one, falling to a flat $3 after year nine. Fixed fees add about $60, and electric vehicles pay another $89.05 in EV and road usage fees for 2026–27. A trade-in lowers the taxable price; rebates don't.

Colorado doesn't charge a flat registration fee, which is why first-time buyers and new arrivals are often surprised by the total. This guide breaks down every piece in plain numbers, with worked examples for a used SUV, a used EV and an older commuter car.

Key takeaways

Sales tax is based on where you register the vehicle, not where you buy it.

A trade-in reduces the taxable price in Colorado; manufacturer rebates do not.

Specific ownership tax is based on the original MSRP and shrinks as the vehicle ages.

EVs pay a $63.05 EV fee plus a $26 road usage fee in 2026–27.

Part 1: Sales tax, paid once

Colorado's state sales tax is 2.9%. Local taxes for RTD, the cultural facilities district, your county and your city stack on top, and the rate that counts is the one for the address where you register the vehicle. A dealer collects state tax plus the local taxes for your jurisdiction; if you buy from a private party, you pay all of it to your county clerk when you register.

Colorado excludes the trade-in value from the taxable price. Rebates do not reduce it, and mandatory dealer fees and destination charges are taxable.

Part 2: Specific ownership tax, paid every year

Specific ownership tax (SOT) is the biggest part of most registration bills. It's based on the vehicle's taxable value, which is 85% of its original MSRP, not the price you paid, and the rate drops as the vehicle ages. That's why registering a three-year-old SUV can cost several hundred dollars while a 12-year-old commuter car costs very little.

Over its first 10 years, the SOT on a $35,000-MSRP vehicle adds up to about $2,368. If you buy that car used at age four, you skip the three most expensive years.

Part 3: The fixed fees

On top of SOT, every registration carries a stack of smaller state and county fees. For a typical car or SUV under 7 years old, the ones below add up to about $60 before the weight-based license fee.

Fee	Typical passenger vehicle (2,001–5,000 lb)	Notes
Road safety surcharge (FASTER)	$19.30	Reduced through Aug. 31, 2027; returns to $23.00 after
Bridge safety surcharge	$18.00
Age-of-vehicle fee	$12, $10 or $7	Under 7 years, 7–9 years, 10+ years
License fee	Varies	Based on vehicle weight
Clerk hire, EMS and POST fees	$7.00	$4 + $2 + $1
Insurance fees	$0.60	$0.50 + $0.10
Emissions program fee	$0.50–$1.50	Depends on area
County road and bridge fee	About $1.50	Set by county
EV fee (battery-electric or plug-in hybrid)	$63.05	Fiscal year 2026–27
Road usage fee	$26 EV / $13 plug-in hybrid	2026–27; rising to $96 / $27 by 2031–32

Worked examples

Here's how the pieces combine for three common Denver purchases. For the first-year total, add the one-time sales tax from Part 1: about $2,662 on a $29,098 used vehicle registered in Denver.

Estimated annual registration, three examples

SOT plus the fixed fees above, before the weight-based license fee

Estimate

2023 SUV, $35,000 MSRP, registered in 2026~$328

Year 4: $267.75 SOT + about $60 in fees

2024 EV, $45,000 MSRP, registered in 2026~$608

Year 3: $459 SOT + about $60 + $63.05 EV fee + $26 road usage fee

2014 sedan, $22,000 MSRP, registered in 2026~$58

Year 10+: $3 SOT + about $55 in fees

Illustrative estimates. Your county's fees and the vehicle's weight change the total. Use the Colorado DMV fee estimator for an exact figure.

Other costs and deadlines

Title fee: $7.20.

Temporary tags: a dealer-issued temp tag is valid for 60 days, with a second one allowed if the county hasn't finished the paperwork.

Emissions: gas vehicles in the Denver metro need a test every two years once they're more than 7 model years old. Air Care Colorado charges $35. All-electric vehicles are exempt.

Private sales: you pay all sales tax at the county clerk, and the seller provides a passing emissions test when one is required.

What could change in 2027

HB26-1430, signed June 4, 2026, sends a fee measure to voters on the Nov. 3, 2026 ballot. If approved, starting Jan. 1, 2027, certain registration fee rates and the road safety surcharge would drop 38%, and the late fee would fall to $15.50 a month, capped at $62. Separately, the road safety surcharge is scheduled to return to $23.00 on Sept. 1, 2027. We'll update this guide after the election.
