What you pay depends on your truck's weight and age

Colorado truck registration fees are based primarily on your vehicle's gross vehicle weight rating (GVWR) — the maximum weight the truck is designed to carry, including cargo and passengers. The heavier the truck, the higher the fee. Your truck's age also matters: newer trucks pay more than older ones in the same weight class.

The Colorado Department of Revenue sets these fees, and they change each year. You'll pay the registration fee when you renew your registration or register a truck for the first time in Colorado. The fee covers your registration certificate and license plate.

You can find your truck's GVWR on a label inside the driver's door jamb or in your owner's manual. This number is different from your truck's actual weight — it's the maximum it can safely weigh when fully loaded.

How weight classes determine your fee

Colorado groups trucks into weight classes, and each class has its own fee schedule. A light-duty pickup truck (under 6,000 pounds GVWR) pays less than a medium-duty truck (6,000 to 10,000 pounds), which pays less than a heavy-duty truck (over 10,000 pounds). The exact fee amounts vary by year.

To find the current fee for your truck's weight class, visit the Colorado Department of Revenue website or call your local county clerk's office. They can tell you the exact fee based on your truck's GVWR and model year. Some county clerk offices also have fee charts posted online.

If you're unsure which weight class your truck falls into, bring your vehicle's registration documents or owner's manual to the county clerk's office. Staff there can help you locate the GVWR and determine your fee.

Age-based fee adjustments

Colorado charges different rates based on how old your truck is. A brand-new truck pays the highest rate in its weight class. As your truck ages, the registration fee decreases. This reduction continues for several years until it reaches the lowest rate for that weight class.

The age brackets vary by weight class, so a 5-year-old light-duty truck may be in a different fee tier than a 5-year-old heavy-duty truck. Your county clerk can tell you which age bracket your specific truck falls into when you register or renew.

When and where you pay registration fees

You pay your truck registration fee at your county clerk's office when you register your truck or renew your registration. Colorado registration is valid for one year from the date you register. You'll receive a renewal notice by mail before your registration expires, usually 30 to 60 days in advance.

You can renew your registration in person at the county clerk's office, by mail, or online through the Colorado Department of Revenue website if your county participates in online renewal. Online renewal is often the fastest option if your truck's information hasn't changed.

Bring your current registration certificate, proof of insurance, and a valid ID when you register or renew in person. If you're registering a truck for the first time in Colorado, you'll also need the title and a bill of sale or previous registration from another state.

What's included in your registration fee

Your registration fee covers your registration certificate (the paper document) and one set of license plates. If you need replacement plates or additional plates, those cost extra and are charged separately.

The registration fee does not include emissions testing, title transfer fees, or late penalties. Some counties charge a small county clerk fee on top of the state registration fee — this varies by location. Ask your county clerk's office about any additional local fees when you register.

Special registration types and different fees

If your truck is used for commercial purposes, you may need a commercial registration instead of a standard registration. Commercial registrations have different fee structures and are based on the truck's use and weight. Trucks registered for personal use pay standard fees; trucks used for business or hauling may pay more.

Vintage or classic trucks (typically 25 years or older) may be registered under Colorado's historic vehicle program, which has lower fees. You'll need to meet specific requirements and use the vehicle only for exhibitions, shows, or parades — not for regular transportation. Contact your county clerk to learn whether your truck qualifies.

Temporary registrations are also available if you need to drive your truck before your permanent registration arrives. These are valid for a short period and cost less than a full-year registration.

How to find your truck's exact fee

The fastest way to find your truck's registration fee is to contact your county clerk's office directly. They have access to the current fee schedules and can calculate your exact fee based on your truck's GVWR and model year. Most county clerk offices can give you a quote over the phone or in person.

You can also visit the Colorado Department of Revenue website, which publishes the statewide fee schedule each year. The schedule shows fees by weight class and vehicle age. Once you know your truck's GVWR and age bracket, you can cross-reference the schedule to estimate your fee.

Keep in mind that fees change annually, usually in January. If you're planning to register a truck soon, ask your county clerk for the current year's fees rather than relying on last year's numbers.

Frequently Asked Questions

Does my truck's actual weight matter, or just the GVWR?

Only the GVWR matters for registration fees. Colorado uses the maximum weight your truck is designed to carry, not what it actually weighs. Even if your truck rarely carries a full load, you pay based on its GVWR.

Can I register my truck online in Colorado?

Many Colorado counties allow online renewal through the Department of Revenue website if your registration information hasn't changed. New registrations and registrations with changes typically require an in-person visit or mail submission to your county clerk's office.

What happens if I register my truck late?

Late registration incurs a penalty fee in addition to your standard registration fee. The penalty amount varies, so contact your county clerk to find out the current late fee. It's cheaper to renew on time or shortly after your registration expires.

Do I pay sales tax on top of the registration fee?

Sales tax is separate from registration fees. You pay sales tax when you purchase the truck, not when you register it. Your registration fee is a flat amount based on weight and age, with no sales tax added.

Are there any discounts or waivers for truck registration fees?

Colorado does not offer discounts on standard truck registration fees based on income or other factors. However, historic vehicle registrations and certain commercial registrations may have different fee structures. Ask your county clerk about programs that might explore to your situation.
