Colorado Vehicle Tax Calculator

Colorado charges 2.9% state sales tax on a vehicle, plus city, county and district taxes based on where you live. In Denver, the total rate is 9.15%. Then every year, you pay specific ownership tax (SOT). It starts at 2.1% of 85% of the original MSRP and drops as the vehicle ages.

Use this Colorado vehicle tax calculator to estimate the sales tax, ownership tax, title and registration fees on a new or used car. It works for dealer and private sales. The guide below explains each charge so you can check the math yourself.

Rates and fees checked against the Colorado Department of Revenue and Colorado DMV on October 7, 2026. This is an independent estimate. Your county motor vehicle office sets the final amount.

Colorado Vehicle Taxes and Fees at a Glance

How Colorado Vehicle Tax Works

Colorado has two separate taxes on a vehicle. Most of the confusion comes from mixing them up.

• Sales or use tax is paid once, when you buy. It’s a percentage of the price.
• Specific ownership tax is paid every year with your registration. It takes the place of a property tax on the vehicle. It’s based on the original MSRP, not what you paid.

Sales tax = (price + dealer fees − trade-in) × (2.9% + your local rate)

Specific ownership tax = MSRP × 85% × the rate for the vehicle’s age

Which local rate applies?

Local tax follows the address where the vehicle will be registered, not the dealer’s city. A dealer collects the state tax and the local taxes it can collect. Your county office collects anything left over before it will title or register the vehicle.

Most of the Denver metro area pays the 1% RTD tax. Home-rule cities like Denver collect their own city tax and can set some of their own rules, so check with your city if you live in one.

What’s Taxed: Trade-Ins, Rebates and Dealer Fees

Does a trade-in lower the tax?

Yes, at a dealer. Colorado leaves the value of your trade-in out of the taxable price, as long as the vehicle you trade in is one that gets registered. A $40,000 car with a $15,000 trade-in is taxed on $25,000.

Are rebates taxed?

Yes. Colorado figures sales tax on the full price before a manufacturer rebate, even if you sign the rebate over to the dealer. A real dealer discount is different. It lowers the price, so it lowers the tax.

Are dealer fees taxed?

Yes, if they aren’t optional. Colorado counts any fee you must pay to buy the car, such as a dealer handling fee or delivery charge, as part of the taxable price.

How Much Is Car Sales Tax in Colorado?

Here’s the sales tax at the state rate alone and at Denver’s 9.15% total. Your total will land somewhere in this range or close to it, depending on your address.

So a $30,000 car in Denver costs about $2,745 in sales tax. Specific ownership tax and registration fees come on top.

Colorado Specific Ownership Tax

Specific ownership tax is the biggest yearly cost of owning a newer car in Colorado. For most passenger vehicles (Tax Class C), the county takes 85% of the original MSRP and applies a rate based on the vehicle’s year of service.

The year is counted from the model year, not from when you bought it. A 2021 model registered in 2026 is in year 6, so it pays 0.45% even if you just bought it. And because SOT uses MSRP, a car you got for a great price still pays SOT on its full sticker value.

Colorado Tax, Title and Registration Examples

Example 1: New SUV from a dealer in Denver

Assumptions: $42,000 price before a $1,500 manufacturer rebate, $799 dealer handling fee, $12,000 trade-in, $43,500 MSRP, 4,200 lbs, financed, registered in Denver.

Add the weight-based license fee and any small county fees to this total. The sales tax alone is $2,818.11.

Example 2: Used car from a private seller

You buy a 2021 sedan from a neighbor for $18,000. Its original MSRP was $28,000. Assume your combined state and local rate is 7.9%. Your actual rate depends on your address.

• Sales tax: $18,000 × 7.9% = $1,422
• SOT, year 6: $28,000 × 85% × 0.45% = $107.10
• Title, surcharges, $12 age fee, small fees and plates: $71.38

Estimated total: $1,600.48, plus the license fee. You pay all of it at your county motor vehicle office when you register.

Example 3: Older car on a budget

You pay $5,000 for a 12-year-old car, with the same 7.9% rate. Sales tax is $395. SOT drops to a flat $3 from year 10. The age fee falls to $7, so the title, surcharges and small fees come to $66.38. Total: about $464.38.

Colorado Title and Registration Fees

Colorado registration is a stack of small fees on top of SOT. Here are the ones you’ll see most often on a passenger car or SUV.

The road safety surcharge goes up by about $3.70 to $4 on September 1, 2027. Counties can also add small road and bridge fees, and the license fee depends on weight.

Electric vehicle and plug-in hybrid fees

Every plug-in vehicle pays a $63.05 yearly fee. On top of that, Colorado adds a road usage fee that steps up each July:

Right now that’s $89.05 a year for an EV and $76.05 for a plug-in hybrid. EVs don’t need emissions tests.

Private Sales and Gifts in Colorado

A private seller doesn’t collect sales tax. Instead, you pay the state and local tax to your county motor vehicle office when you register, along with SOT and fees. You have 60 days from the purchase date to register.

Bring the signed title, a bill of sale, proof of insurance and an emissions test if your area requires one.

Is a gifted car taxed?

No sales or use tax is due from you when you receive a vehicle as a true gift. You’ll still pay SOT and the registration fees.

Moving to Colorado or Buying Out of State

New residents

If you bought your vehicle somewhere else and brought it with you when you moved, you don’t pay Colorado use tax on it. You have 90 days to register. You’ll pay SOT and fees, and you’ll need a VIN verification (form DR 2698). An emissions test is needed if you live in a testing area.

Buying a car in another state

If you live in Colorado and buy a car out of state, you owe Colorado use tax when you register it. You get credit for sales tax you already paid to the other state.

So buying across the border won’t drop your tax below what you’d owe at home. If you’re shopping in a neighboring state, check the Wyoming tax, title and license rules or Utah vehicle tax and fees first, then plan for the Colorado bill when you register.

Active-duty military

Certain active-duty service members can qualify for a registration fee exemption and pay only $1 in SOT. Since August 12, 2026, Colorado accepts military orders as proof instead of a signed affidavit (HB26-1200). Ask your county office which benefits fit your situation.

See also: Wyoming: a 4% state sales tax plus local taxes.

Emissions Testing

Most vehicles in the Denver metro area and the North Front Range need an emissions test. New gas vehicles skip testing for their first seven model years, and new diesels for four. After that, a test is needed when the vehicle is sold and when a new resident registers it. All-electric vehicles are exempt.
