How Colorado registration renewal works

Colorado sends you a renewal notice by mail 30 to 60 days before your registration expires. The notice includes your renewal fee, which depends on your vehicle's age and weight. You can renew online through the Colorado Department of Revenue website, by mail, or in person at a county clerk's office. Online renewal is the fastest route — you pay by credit or debit card and receive your new registration when ready as a printable document.

You do not need an inspection to renew in Colorado unless your vehicle is more than 7 years old and has never been inspected in the state, or if you are renewing after a lapse of more than 12 months. If an inspection is required, you must complete it before you can finish the renewal process. The inspection checks emissions and safety equipment and costs between $10 and $20 depending on your vehicle type.

Key Takeaways

  • Colorado sends renewal notices 30 to 60 days before expiration, and you can renew online, by mail, or at a county clerk's office.
  • Vehicles older than 7 years that have never been inspected in Colorado require an emissions and safety inspection before renewal.
  • Online renewal is the fastest method and gives you a printable registration document when ready after payment.
  • Your renewal fee is based on your vehicle's age and weight, and the amount appears on your renewal notice.
  • If your registration has lapsed for more than 12 months, you must complete an inspection and may face a late penalty.

Renewing online through the Colorado Department of Revenue

Go to the Colorado Department of Revenue's online renewal portal at dmv.colorado.gov. Enter your vehicle identification number (VIN), license plate number, and the last four digits of your Social Security number or federal employer identification number. The system will pull up your vehicle record and show your renewal fee.

Review the fee amount and vehicle information for accuracy. If anything is wrong — your address, vehicle weight, or other details — you will need to correct it before paying. Pay by credit card or debit card. Once payment processes, you can print your new registration when ready. Colorado also emails a copy to the address on file. You do not need to visit an office or wait for anything to arrive by mail.

Keep your printed registration in your vehicle. It is valid when ready and serves as proof of registration until your physical registration card arrives by mail, which typically takes 7 to 10 business days.

Renewing by mail or at a county clerk's office

If you prefer not to renew online, use the renewal notice Colorado sent you. Fill out the form, include a check or money order for the renewal fee, and mail it to the address shown on the notice. Processing takes 2 to 3 weeks from the date the county clerk receives it.

To renew in person, visit your county clerk's office with your renewal notice and payment method (cash, check, or card). Bring your vehicle's current registration or VIN if you do not have the notice. The clerk will process your renewal on the spot, and you will receive your new registration card when ready. County offices are open during standard business hours, and wait times vary by location and time of day.

When you need an inspection before renewal

Colorado requires an inspection if your vehicle is more than 7 years old and has never been inspected in the state, or if your registration has lapsed for more than 12 months. The inspection covers emissions (for vehicles 1975 and newer) and safety equipment like brakes, lights, and wipers.

Find an inspection station through the Colorado Department of Revenue website or by searching "emissions inspection near me." The inspection costs $10 to $20 and takes about 15 minutes. Once you pass, the station sends the results to the state electronically. You can then complete your renewal online, by mail, or in person. If you fail, you have 30 days to fix the problem and retest at no additional cost.

Late renewal and penalties

If your registration expires and you do not renew within 30 days, you cannot legally drive the vehicle. Driving with an expired registration can result in a traffic ticket and fine. If your registration has been expired for more than 12 months, you must complete an inspection before renewal, even if your vehicle would not normally require one.

Colorado does not charge a specific late fee for renewal, but you will owe the standard renewal fee plus any applicable taxes. If you are unsure whether your registration is current, check the expiration date on your registration card or log into the Colorado Department of Revenue website with your VIN and last four digits of your Social Security number.

Address changes and other registration updates

If you moved since your last registration, update your address before renewing. You can change your address online through the Colorado Department of Revenue website, by mail using the form included with your renewal notice, or in person at a county clerk's office. Updating your address does not cost extra and can be done at the same time as renewal.

If you need to change the vehicle owner, add or remove a lienholder, or update other registration details, you will need to visit a county clerk's office or mail in a form. These changes cannot be made through online renewal. Contact your county clerk for the specific form and instructions.

What to do if you did not receive a renewal notice

If your renewal notice did not arrive in the mail, you can still renew online or in person without it. Go to the Colorado Department of Revenue website and enter your VIN, license plate number, and the last four digits of your Social Security number. The system will show your vehicle record and renewal fee. If you cannot access the online system, call the Colorado Department of Revenue at 303-205-5600 or visit a county clerk's office with your vehicle registration and identification.

If your address on file is incorrect, the renewal notice may have gone to the wrong place. Update your address through the online system or at a county clerk's office, and a new notice will be mailed to the correct address.

Frequently Asked Questions

Can I renew my Colorado registration if it has been expired for more than a year?

Yes, but you must complete an emissions and safety inspection first, even if your vehicle would not normally require one. Once you pass the inspection, you can renew online, by mail, or in person. You will owe the standard renewal fee with no additional late penalty.

How long does it take to renew online?

Online renewal takes about 5 to 10 minutes to complete. You receive a printable registration when ready after payment. Your physical registration card arrives by mail in 7 to 10 business days, but the printed version is valid right away.

What if my vehicle fails the inspection?

You have 30 days to repair the problem and retest at the same inspection station at no additional cost. Once you pass, the station reports the results to the state, and you can complete your renewal. If you do not retest within 30 days, you will need to pay for a new inspection.

Do I need to renew my registration if I sold my vehicle?

No. Once you sell your vehicle, you should notify the Colorado Department of Revenue by submitting a bill of sale or other proof of sale. You do not renew the registration after the sale. The new owner will register the vehicle in their name.

Can I renew my registration if I have an outstanding ticket or fine?

Colorado does not block registration renewal based on unpaid traffic tickets or fines. However, if you have an active suspension or hold on your driver's license, you may not be able to renew. Contact the Colorado Department of Revenue or your county clerk to check your status before attempting to renew.
