What happens when you renew a Colorado vehicle registration
When your Colorado vehicle registration expires, you renew it by paying a fee to the Colorado Department of Revenue and providing proof that your vehicle still meets state requirements — mainly that it passed emissions testing (if required in your county) and that you have current auto insurance. The state will mail you new registration documents and a new license plate sticker, or you can pick them up in person at a county clerk's office.
You can renew by mail, online, in person, or through an authorized third-party agent like a car dealership or title service. The process takes about two weeks by mail, a few minutes online, or when ready if you go in person. You do not have to renew on the exact expiration date — you can renew up to six months before it expires, which many people do to avoid the rush.
Key Takeaways
- Colorado lets you renew online, by mail, in person at your county clerk's office, or through an authorized agent, and each method takes different amounts of time.
- You will need your current registration documents, proof of insurance, and an emissions test result if your vehicle is required to test in your county.
- The renewal fee depends on your vehicle's weight and age, and varies slightly by county because some counties add a local surcharge.
- You can renew up to six months before your registration expires, so you do not have to wait until the last moment.
- If you renew online or by mail, the state mails your new sticker and documents to the address on file, which usually takes two weeks.
Renewing online through the Colorado Department of Revenue website
The fastest way to renew is through the Colorado Department of Revenue's online portal at dmv.colorado.gov. You will need your current registration documents, your vehicle identification number (VIN), and your driver's license number. The system will ask you to confirm your vehicle information, upload or confirm your proof of insurance, and pay the renewal fee with a credit or debit card.
Online renewal takes about five to ten minutes. The state will mail your new registration sticker and documents to the address on file within two weeks. If you need the sticker sooner, you can pay an extra fee to have it mailed faster, or you can pick it up in person at your county clerk's office the next business day.
Not all vehicles can renew online — commercial vehicles, vehicles with outstanding violations or liens, and some specialty plates must renew in person or by mail. The online system will tell you when ready if your vehicle is not may be able to access.
Renewing by mail with the county clerk
To renew by mail, contact your county clerk's office and request a renewal form, or read it from the Colorado Department of Revenue website. Fill out the form, include a copy of your proof of insurance, and mail it along with a check or money order to your county clerk. Include your current registration documents so the clerk can match them to your account.
Mail renewal takes about three to four weeks from the time the clerk receives your envelope. The state will mail your new sticker and documents to the address you provide. If you are unsure whether your vehicle requires an emissions test, call your county clerk before mailing — if you send the form without the test result and your vehicle needs one, the clerk will send it back and delay your renewal.
Renewing in person at your county clerk's office
Walk into your county clerk's office with your current registration documents, proof of insurance, and your driver's license. If your vehicle requires an emissions test, bring the test result or be prepared to get one before the clerk will process your renewal. The clerk will verify your information, collect the renewal fee, and issue you a new registration sticker on the spot.
In-person renewal takes about 15 to 30 minutes depending on how busy the office is. You can drive away with your new sticker the same day. Most county clerk offices are open Monday through Friday during business hours, though some offer extended hours or Saturday appointments. Check your county clerk's website for hours and whether you need to make an appointment.
Understanding emissions testing requirements
Colorado requires emissions testing for vehicles in certain counties — mainly the Denver metro area and a few other urban regions. Your current registration documents will say whether your vehicle is subject to testing. If it is, you must get a test before you renew, and you must bring the test result with your renewal process.
Emissions tests cost between $20 and $30 and take about 15 minutes at any authorized testing station. You can find testing stations through the Colorado Department of Public Health and Environment website. The test result is valid for 90 days, so you can get tested before your registration expires and use that result when you renew. If your vehicle fails the test, you will need to have it repaired and tested again before you can renew.
What to do if your registration has already expired
If your registration expired more than 30 days ago, you cannot renew online — you must renew in person at your county clerk's office or by mail. You may also face a late fee in addition to the regular renewal fee. Bring your current registration documents, proof of insurance, and your driver's license to the clerk's office.
Driving with an expired registration can result in a traffic citation, so renew as soon as you notice the expiration date has passed. If you were unaware the registration expired, bring that information when you renew in person — some clerks will waive or reduce the late fee in those situations, though it is not may provide.
Renewing through an authorized third-party agent
Some car dealerships, title services, and other businesses are authorized to process vehicle registrations on behalf of the state. These agents can renew your registration and issue you a new sticker the same day, though they charge a service fee on top of the state renewal fee — usually between $10 and $25 depending on the agent.
Using an agent is convenient if you are already at a dealership or if your county clerk's office has long wait times. Call ahead to confirm the agent handles renewals and ask what documents and fees they need. Not all agents renew all types of vehicles, so check before you make the trip.
Frequently Asked Questions
How much does it cost to renew a Colorado registration?
The renewal fee depends on your vehicle's weight and age. A typical passenger car costs between $150 and $200 per year. Some counties add a local surcharge of $10 to $30. If you renew online or through an agent, you may pay a processing fee on top of the state fee. Check your current registration documents or call your county clerk for the exact amount for your vehicle.
Can I renew if my vehicle has a lien on it?
If a lender holds a lien on your vehicle, you can still renew your registration. You do not need the lender's permission. Bring your current registration documents and proof of insurance to your county clerk's office or submit them online. The registration documents will show the lien holder's name, but that does not affect your ability to renew.
What if I moved and my address changed since my last registration?
Update your address with the Colorado Department of Revenue before you renew, or provide your new address when you renew. If you renew online, the system will ask for your current address. If you renew in person or by mail, tell the clerk your new address so the state mails your new sticker to the correct location. You can update your address on the DMV website without renewing.
Do I need to renew my license plate itself, or just the sticker?
You only need to renew the sticker that goes on your existing plate. Colorado does not require you to get a new plate every year unless the plate is damaged or you want to change to a specialty plate. The sticker shows the current year and proves your registration is current. If your plate is bent, cracked, or unreadable, you can request a replacement plate from your county clerk for a small fee.
What happens if I forget to renew before the expiration date?
Your registration becomes invalid on the expiration date, and driving with an expired registration is a traffic violation. You can be stopped and cited. Renew in person at your county clerk's office as soon as you notice the expiration has passed. You will likely owe a late fee in addition to the regular renewal fee, though some clerks may reduce or waive it depending on the circumstances.
