What Colorado requires to register a vehicle

To register a car in Colorado, you need to submit an process to the Colorado Department of Revenue, Division of Motor Vehicles (DMV), along with proof of ownership, proof of residency, and payment of the registration fee. The state requires this whether you're registering a new vehicle, a used car you've bought, or a vehicle you've moved to Colorado from another state.

Colorado registration is valid for one or two years depending on your vehicle type and when you register. Passenger vehicles typically renew annually, though some newer vehicles may have two-year registration options. You'll receive renewal notices by mail before your registration expires, and you can renew online, by mail, or in person at a DMV office.

Key Takeaways

  • You must provide a title or proof of ownership, a Colorado driver's license or ID showing your current address, and payment to the DMV in order to register.
  • If you're registering a used vehicle you purchased, bring the signed title from the seller and proof that you paid sales tax or are exempt from it.
  • Colorado offers online registration renewal through the DMV website, which is faster than visiting an office if your vehicle information hasn't changed.
  • Registration fees vary based on vehicle type, weight, and age, so the cost depends on what you're registering.
  • If you move to Colorado from another state, you have 30 days to register your vehicle before driving with out-of-state plates becomes a violation.

Documents you need to bring or submit

Start with your vehicle's title or proof of ownership. If you bought the car from a dealer, you'll receive a temporary registration document and the title process. If you bought it from a private seller, the seller must sign the back of the title and give it to you. If the title is held by a lender, you'll need written permission from them to register the vehicle in your name.

Next, bring proof of Colorado residency. A Colorado driver's license or ID card with your current address is the standard document. If you don't have one yet, a utility bill, lease agreement, or mortgage statement dated within the last 60 days will work. You'll also need to show proof that sales tax was paid on the vehicle. If you bought it from a Colorado dealer, they usually handle this. If you bought it privately or out of state, you may need a receipt or bill of sale showing the purchase price.

Bring your Social Security number or federal tax ID, your vehicle's VIN (Vehicle Identification Number), and the odometer reading. If the vehicle is financed, bring the lender's name and loan number. Have payment ready—Colorado accepts cash, check, debit card, or credit card depending on whether you're registering in person or online.

How to register in person at a DMV office

Find your nearest DMV office on the Colorado Department of Revenue website. Walk in during business hours with all required documents and payment. Most offices operate on a first-come, first-served basis, though some allow you to reserve a time slot online. Bring originals of all documents—photocopies are not accepted for the title.

The DMV staff will verify your documents, calculate your registration fee based on vehicle type and weight, and process your process. You'll receive your registration certificate and license plates (or a registration sticker if you're keeping existing plates) on the spot or by mail within a few days. The entire process usually takes 30 minutes to an hour, depending on how busy the office is.

Registering online or by mail

Colorado's DMV allows online registration renewal if your vehicle information hasn't changed and you're not registering a new vehicle for the first time. Log into the Colorado DMV website, enter your vehicle information, and pay the fee with a debit or credit card. You'll receive your registration certificate and renewal sticker by mail within 7 to 10 business days.

For initial registration of a new or used vehicle, you must register in person or by mail. To register by mail, complete the process form (available on the DMV website), include copies of your title and proof of residency, and mail everything to the address listed on the form along with payment. Processing by mail takes 2 to 3 weeks. This option works if you can't visit an office, but it's slower than in-person registration.

Registration fees and what affects the cost

Colorado registration fees depend on your vehicle's type, age, and weight. A standard passenger vehicle typically costs between $100 and $200 for a one-year registration, but the exact amount varies. Trucks, RVs, motorcycles, and commercial vehicles have different fee structures. Vehicles over 10 years old may have lower fees than newer ones.

You may also owe sales tax if you haven't paid it already. Colorado's sales tax rate is 2.9% statewide, plus any local taxes in your county, which can add another 3% to 8% depending on where you live. If you bought the vehicle out of state and didn't pay Colorado sales tax, you'll owe it when you register. The DMV will calculate this based on the vehicle's purchase price.

Registering a vehicle you bought from a private seller

When you buy a car from a private seller in Colorado, the seller must sign the back of the title and give it to you. Make sure the title is clear (not held by a lender) or that you have written permission from the lender. You'll also need a bill of sale showing the purchase price—this is what the DMV uses to calculate sales tax owed.

Take the signed title, bill of sale, proof of residency, and payment to a DMV office. If the seller didn't sign the title correctly or left it blank, the DMV will reject it and you'll have to go back to the seller to fix it. This is why it's important to complete the title transfer at the time of sale, not later. If you can't locate the seller afterward, contact the DMV about your options.

Moving to Colorado with an out-of-state vehicle

If you move to Colorado and bring a vehicle registered in another state, you have 30 days to register it in Colorado. After 30 days, driving with out-of-state plates is a violation and you can be stopped by law enforcement. You don't need to wait for your out-of-state registration to expire—register in Colorado as soon as you establish residency.

Bring your out-of-state title, proof of Colorado residency (such as a lease or utility bill), your Colorado driver's license or ID if you have one, and proof of sales tax payment or exemption. If you bought the vehicle in another state and didn't pay Colorado sales tax, you'll owe it when you register. The DMV will issue you new Colorado plates and a registration certificate.

Frequently Asked Questions

Can I register my car online if I just bought it?

No. Online registration is only for renewing existing Colorado registrations. If you're registering a vehicle for the first time in Colorado—whether it's new, used, or from out of state—you must register in person at a DMV office or by mail. Once your initial registration is complete, you can renew online in future years.

What happens if I don't register within 30 days of moving to Colorado?

Driving with out-of-state plates after 30 days is a violation. Law enforcement can stop you and issue a citation. You'll be required to register the vehicle when ready. It's better to register as soon as you have proof of Colorado residency, even if your out-of-state registration hasn't expired yet.

Do I need to register a vehicle if I'm only visiting Colorado temporarily?

No. If you're visiting and your vehicle is registered in another state, you can drive on those plates for the duration of your visit. Registration is required only if you establish Colorado residency, which typically means getting a Colorado driver's license or ID, signing a lease, or buying property in the state.

What if the title is in someone else's name?

The title must be in your name or jointly in your name and another person's name before you can register it. If you bought the vehicle but the title is still in the seller's name, ask the seller to sign it over to you. If the title is in a lender's name, you'll need written permission from the lender to register it. Contact the DMV if you're unsure how to proceed with your specific situation.

Can I register a vehicle that has a lien on it?

Yes. If you financed the vehicle, the lender holds a lien but you can still register it in your name. Bring the lender's name and loan number, and the DMV will note the lien on your registration. You don't need the lender's permission to register, but you do need it to sell or transfer the title later.
