What Colorado requires for car registration

Colorado's Department of Revenue handles vehicle registration, not a separate DMV office. You register a car by submitting documents to the county assessor's office in the county where you live, or by mail to the state. Registration covers your license plate, vehicle identification, and proof that you own the car legally.

The state requires a completed process for Vehicle Registration (Form DR 2261) signed by all owners listed on the title. You must provide your current title document, proof of Colorado residency (a utility bill, lease, or mortgage statement dated within 60 days), and a valid ID. If you're registering a vehicle with a lien, the lienholder's name must appear on the title.

Colorado charges registration fees based on vehicle weight and age. Passenger cars typically cost between $85 and $150 for the first registration, though the exact amount depends on the vehicle's dry weight in pounds. The state also charges a $10 registration process fee. If you're registering a vehicle from out of state, you may owe sales tax on the purchase price if you haven't already paid it.

Where to register in person

Each of Colorado's 64 counties operates its own assessor's office, and that office handles vehicle registration for residents in that county. You can find your county assessor's contact information and hours on the Colorado Department of Revenue website by searching for your county name. Some offices accept walk-ins during business hours; others require an appointment.

Bring the original title, your proof of residency, your ID, and the completed DR 2261 form. If you have a lien on the vehicle, bring documentation showing the lienholder's name and address. The assessor's office will issue your license plate and registration card on the spot or within a few days, depending on the office's processing speed.

If you cannot visit your county assessor's office in person, you can mail your documents to the Colorado Department of Revenue, Motor Vehicle Section, 1881 Pierce Street, Lakewood, CO 80214. Include a check or money order for the registration fee and process fee. Processing by mail typically takes two to three weeks.

Registering a vehicle you just bought

When you buy a car in Colorado from a dealer or private seller, the seller must sign the title and give it to you. If you financed the purchase, the lender's name will appear on the title as the lienholder. You then take the signed title to your county assessor's office to register the vehicle in your name.

If you bought the car out of state, you have 30 days from moving to Colorado to register it. Bring the out-of-state title, your proof of Colorado residency, and your ID. The assessor's office will issue a new Colorado title and registration. If you haven't paid Colorado sales tax on the purchase, you will owe it at registration; the assessor's office calculates the amount based on the purchase price you report.

If the title has a lien, the lienholder must sign the title before you can register it. Some lenders mail the signed title directly to you; others require you to request it. Contact your lender if you do not have the signed title within a few days of closing the purchase.

Renewing your registration online

Colorado allows online renewal through the Department of Revenue website if your vehicle has not changed ownership and you have not made major changes to it (such as adding a trailer or changing the engine). You can renew up to 90 days before your registration expires.

Log in with your driver's license number and date of birth, then follow the prompts to review your vehicle information and pay the renewal fee. The state will mail your new registration card and license plate (if needed) within two weeks. Online renewal costs the same as in-person renewal and takes about the same time to process.

If you cannot renew online—for example, if you have a lien, a title problem, or an address change—you must renew in person at your county assessor's office or by mail to the state.

What happens if your registration expires

Driving with an expired registration is illegal in Colorado. A police officer can stop you and issue a citation, which carries a fine. If your registration has been expired for more than 30 days, you may also face a penalty fee when you renew.

If you miss your renewal important date, you can still renew at your county assessor's office or by mail. The renewal process is the same, but you may owe a late fee in addition to the standard registration fee. Some counties charge $10 to $25 for late renewal; check with your assessor's office for the exact amount.

If your vehicle is registered but you no longer own it, you must notify the Colorado Department of Revenue in writing. Send a letter to the Motor Vehicle Section at the Lakewood address above, stating that you no longer own the vehicle and the date you sold or disposed of it. This removes your liability for the vehicle.

Registering a vehicle with a salvage or rebuilt title

If you buy a vehicle that has been declared a total loss by an insurance company, it receives a salvage title. If the vehicle is then repaired and passes a state inspection, it can be issued a rebuilt title. Colorado allows registration of rebuilt-title vehicles, but the process differs from standard registration.

To register a rebuilt-title vehicle, you must first have it inspected by a Colorado State Patrol officer or an authorized inspection station. The inspection verifies that the vehicle is safe and that the repairs match the damage history on the title. Bring the salvage title, proof of repairs, and your ID to the inspection. Once you pass, you receive an inspection certificate.

Take the inspection certificate and the salvage title to your county assessor's office to register the vehicle. The assessor will issue a rebuilt title and registration. Registration fees for rebuilt-title vehicles are the same as for standard vehicles. A rebuilt title remains on the vehicle permanently and will be disclosed to any future buyer.

Transferring registration when you move within Colorado

If you move to a different county in Colorado, you must update your registration with your new address. You can do this by mail or in person at your new county assessor's office. Bring your current registration card, proof of your new address (a utility bill or lease dated within 60 days), and your ID.

The assessor's office will issue a new registration card with your updated address. You do not need a new license plate unless your old plate is damaged or you want a personalized plate. The address change is free and takes a few minutes in person or one to two weeks by mail.

If you move out of state, you must cancel your Colorado registration. Contact your county assessor's office or the Motor Vehicle Section to request cancellation. You will not receive a refund of registration fees, but canceling removes your liability for the vehicle in Colorado.

Frequently Asked Questions

Can I register a car if I don't have a Colorado driver's license?

Yes. You need a valid ID—a driver's license, passport, or state ID card—but it does not have to be from Colorado. You also need proof of Colorado residency, such as a utility bill or lease in your name dated within 60 days.

What if the title has the wrong name or spelling?

Contact the Colorado Department of Revenue or the county assessor's office before you register. You may need a corrected title from the previous owner or from the state where the vehicle was last registered. Do not attempt to register a title with errors; the assessor's office will reject it.

How long does registration take if I mail my documents?

Processing by mail typically takes two to three weeks from the date the Motor Vehicle Section receives your documents. Mail your process to 1881 Pierce Street, Lakewood, CO 80214. Include a check or money order and keep a copy of everything you send.

Do I need to register a vehicle I'm only keeping temporarily?

Yes, if you drive it on public roads in Colorado. Even a borrowed or inherited vehicle must be registered in the owner's name. If you plan to keep the vehicle only briefly, you can still register it; there is no minimum ownership period.

What if my vehicle has a lien and the lender won't sign the title?

Contact your lender and request the signed title. Most lenders sign and mail the title automatically when you pay off the loan. If the lender refuses or is unresponsive, contact the Colorado Department of Revenue Motor Vehicle Section for guidance on how to proceed.
