Where to renew your Colorado vehicle tag

You can renew your Colorado vehicle registration online through the Colorado Department of Revenue website, by mail, or in person at your county clerk's office. The online option is fastest — you can complete it in minutes from home, and your new registration is emailed to you when ready. Mail renewal takes about two weeks. In-person renewal at the county clerk's office is useful if you need to handle other vehicle matters at the same time, like address changes or title transfers.

Which method works best depends on whether your vehicle information has changed. If your address, vehicle details, or ownership are the same as last year, online renewal is straightforward. If you've moved, changed your name, or made modifications to the vehicle, you may need to visit in person or call your county clerk first to confirm what documents they need.

Key Takeaways

  • Colorado vehicle registration renews online at the Department of Revenue website, by mail, or at your county clerk's office, with online being the fastest option.
  • You will need your current registration card, vehicle identification number (VIN), and a valid payment method to renew online.
  • Registration renewal fees vary by vehicle weight and type, and you can find your exact fee on the Department of Revenue website before you pay.
  • Your new registration is valid when ready after online payment, though the physical card arrives by mail within two weeks.
  • If your vehicle information has changed since last renewal, contact your county clerk before renewing to confirm what documents are required.

What you need to renew online

To renew online, have your current registration card in front of you. You will also need your vehicle identification number (VIN), which appears on your registration card, your vehicle's title, and your dashboard. The online system will ask you to confirm your vehicle details and your mailing address. If either has changed, you may be directed to complete the renewal by mail or in person instead.

You will also need a valid payment method — a debit card, credit card, or electronic check. Colorado charges a convenience fee for online credit and debit card payments, but not for electronic check payments. The total cost includes your registration fee (which depends on your vehicle's weight and type) plus any applicable local taxes or fees.

Registration fees and what affects the cost

Colorado registration fees are based on your vehicle's dry weight — the weight of the vehicle itself, not including fuel or cargo. Heavier vehicles cost more to register. The state also charges a $10 registration fee that applies to all vehicles, plus a $5.50 emission testing fee if your vehicle is subject to testing. Some counties add local fees on top of the state fee.

You can look up your exact fee before you renew by entering your vehicle information on the Department of Revenue website. This lets you know the total cost before you commit to payment. If your vehicle's weight classification has changed — for example, if you added a heavy aftermarket bed to a truck — the fee may be different from last year.

Timeline: when your renewal takes effect

If you renew online, your registration is valid when ready after payment. You can legally drive your vehicle right away, even though your physical registration card arrives by mail. The card typically arrives within two weeks. Until it arrives, carry your current registration card and your payment confirmation email as proof of renewal if you are stopped by law enforcement.

If you renew by mail, allow at least two weeks for processing. If you renew in person at your county clerk's office, you usually receive your new card the same day. Your registration expires on the date printed on your current card, so renew before that date to avoid driving with an expired registration.

Renewing by mail or in person

To renew by mail, contact your county clerk's office to request a renewal form, or read it from the Department of Revenue website. Complete the form, include your payment, and mail it to your county clerk. Include a check or money order — do not send cash. Mail renewal takes longer than online, so send it at least three weeks before your registration expires.

To renew in person, visit your county clerk's office during business hours with your current registration card and a valid payment method. Bring your ID as well. If your address or vehicle information has changed, bring documents that support the change — a utility bill for an address change, for example. The clerk will process your renewal on the spot and issue your new card when ready.

What to do if your registration has expired

If your registration has already expired, you can still renew through any of the three methods — online, by mail, or in person. Driving with an expired registration can result in a traffic citation, so renew as soon as you notice. The renewal process is the same whether your registration is current or expired; there is no additional penalty fee from the state for late renewal.

However, if your vehicle has been unregistered for a long time — typically more than a year — your county clerk may require you to renew in person and may ask for proof that the vehicle is still in use. Contact your county clerk's office to confirm what they need before you attempt to renew.

Changes to your vehicle or address

If you have moved since your last renewal, update your address before you renew. You can do this online through the Department of Revenue website, or you can provide your new address when you renew. If you have made significant changes to your vehicle — such as adding a commercial bed, changing the fuel type, or modifying the body style — contact your county clerk before renewing. These changes may affect your registration fee or require a new title.

If you have changed your name due to marriage, divorce, or legal change, you will need to update your title before you renew your registration. Contact your county clerk's office for the process and required documents. Do not attempt to renew online if your name on the registration does not match your current legal name.

Frequently Asked Questions

Can I renew my Colorado registration if I just moved out of state?

No. Colorado registration is only for vehicles registered to Colorado residents or businesses. If you have moved out of state, you must register your vehicle in your new state. Contact your new state's motor vehicle department to begin that process. You should not renew your Colorado registration after you move.

What happens if I drive with an expired registration?

Driving with an expired registration is a traffic violation in Colorado. Law enforcement can issue a citation, which typically results in a fine. The fine amount depends on how long your registration has been expired. Renew as soon as you notice the expiration date has passed.

Do I need an emissions test to renew my registration?

It depends on your vehicle's age, type, and where you live. Vehicles in the Denver metro area and some other counties are subject to emissions testing. The Department of Revenue website will tell you whether your vehicle needs testing. If it does, you must complete the test before you renew your registration online.

Can someone else renew my registration for me?

Yes, if you renew by mail or in person. For mail renewal, have someone mail your completed form and payment on your behalf. For in-person renewal, someone with power of attorney or a family member can visit the county clerk's office with your registration card and payment. Online renewal requires your personal information, so you would need to do it yourself or provide your login credentials to someone you trust.

How long is my Colorado registration valid?

Colorado vehicle registrations are valid for one year from the expiration date on your current card. Your registration card shows the exact expiration date. You can renew up to 30 days before expiration without penalty.
