Colorado registration costs depend on your vehicle type, weight, and whether you're registering for the first time or renewing

Colorado charges a base registration fee plus an additional fee based on your vehicle's dry weight (the weight without fuel or cargo). The base fee is the same for all vehicles, but the weight-based fee is what makes the total vary. A passenger car typically costs less than an SUV or truck because it weighs less. You'll also pay a county-specific fee that varies by where you live—some counties add $5 to $15 on top of the state fee.

First-time registrations and renewals cost the same amount in Colorado. The state doesn't charge extra for new registrations. You pay once every two years when you renew, and the cost stays consistent across renewal cycles unless the state legislature changes the fee structure.

Electric vehicles and hybrid vehicles are not exempt from registration fees in Colorado, though some states offer discounts for them. Colorado treats them the same as gas-powered vehicles for registration purposes.

Key Takeaways

  • Colorado registration fees are based on a flat base fee plus a weight-based fee determined by your vehicle's dry weight.
  • County fees add $5 to $15 depending on where you register your vehicle, so your total cost varies by location.
  • Registration is valid for two years, and renewal costs the same as initial registration.
  • You can renew online through the Colorado Department of Revenue website, by mail, or in person at your county clerk's office.

How Colorado calculates the weight-based fee

The weight-based portion of your registration fee is tied to your vehicle's dry weight in increments. Colorado groups vehicles into weight brackets, and each bracket has its own fee. A vehicle weighing 3,000 pounds falls into a different bracket than one weighing 5,500 pounds, and the fee difference can be $20 to $40 or more depending on the brackets.

You can find your vehicle's dry weight in your owner's manual, on the driver's side door jamb, or by contacting the manufacturer. The dry weight is not the same as the Gross Vehicle Weight Rating (GVWR), which is the maximum weight the vehicle can safely carry when loaded. Colorado uses dry weight, so don't confuse the two.

The Colorado Department of Revenue publishes the current weight brackets and fees on its website. If you know your vehicle's weight, you can look up the exact fee before you register or renew.

County fees and where to register

In addition to the state base fee and weight-based fee, your county adds its own fee. This county fee is collected by your county clerk's office and goes to county services. Counties with higher populations or different funding needs may charge more than rural counties. The difference is usually small—$5 to $15—but it does add to your total.

You register your vehicle in the county where you live, not where you bought it or where you work. If you move to a different county in Colorado, you don't have to re-register when ready, but when your registration expires, you'll renew it in your new county and pay that county's fee.

Registering a vehicle for the first time in Colorado

When you register a vehicle in Colorado for the first time—whether it's new to you or you've just moved to the state—you'll need your title or proof of ownership, a bill of sale if applicable, and proof of a Colorado address. You'll pay the base fee, weight-based fee, and county fee all at once. The registration is valid for two years from the date you register.

If you're registering a vehicle you just purchased from a dealer, the dealer may handle the registration paperwork for you and charge a documentation fee. If you're registering a used vehicle you bought privately, you handle the registration yourself at your county clerk's office or online through the Colorado Department of Revenue.

Renewing your Colorado registration

Colorado sends renewal notices about 60 days before your registration expires. You can renew online, by mail, or in person. Online renewal is the fastest option and takes a few minutes. By mail, you send your renewal notice and payment to your county clerk's office. In person, you visit your county clerk's office with your renewal notice and payment method.

The renewal fee is the same as the initial registration fee—base plus weight-based plus county fee. You don't pay extra for renewing. Renewing early is allowed; you can renew up to six months before your current registration expires, and the new registration will start when the old one ends.

Special registration types and their costs

Colorado offers several registration options beyond standard two-year registration. Temporary registration, issued when you buy a vehicle and are waiting for permanent plates, costs less and is valid for 30 days. Dealer plates, used by car dealers for test drives and transportation, have their own fee structure. Antique vehicle registration (for vehicles 25 years or older) may have different fees depending on the county.

Commercial vehicles, trucks used for business, and vehicles registered as commercial have different fee structures based on their use and weight. If your vehicle is primarily for personal use, you'll register it as a passenger vehicle. If it's used for business or hauling, you may need a commercial registration, which can cost more.

What happens if you don't renew on time

If your registration expires and you don't renew, you cannot legally drive the vehicle on Colorado roads. Driving with expired registration can result in a traffic citation and fine. If you're pulled over, the officer will cite you for expired registration, which is a separate violation from any other traffic offense.

If your registration has been expired for more than 30 days, you may need to pay a late fee in addition to the regular registration fee when you renew. The late fee amount varies, so check with your county clerk's office or the Colorado Department of Revenue website for the current amount.

Frequently Asked Questions

How much does it cost to register a car in Colorado?

The total cost depends on your vehicle's weight and your county. A typical passenger car might cost $100 to $150 total, including the state base fee, weight-based fee, and county fee. Check the Colorado Department of Revenue website and enter your vehicle's weight to see the exact amount for your county.

Can I register my vehicle online?

Yes. You can renew online through the Colorado Department of Revenue website if your registration is current or expired less than 60 days. First-time registrations and registrations expired more than 60 days require you to visit your county clerk's office or mail in your paperwork.

Do I need emissions testing to register in Colorado?

It depends on your county and vehicle age. Counties in the Denver metro area and some others require emissions testing for vehicles under 6 years old. Rural counties may not require it. Your renewal notice will tell you if emissions testing is required for your vehicle.

What if I sell my vehicle before the registration expires?

You don't get a refund for unused registration time. Once you sell the vehicle, the new owner must register it in their name. You should notify the Colorado Department of Revenue that you've sold the vehicle to avoid liability for traffic violations or parking tickets issued after the sale.

Does Colorado charge different fees for electric vehicles?

No. Electric vehicles and hybrids pay the same registration fees as gas-powered vehicles based on their weight. Colorado does not offer a registration discount for electric or hybrid vehicles.
