Connecticut registration renewal happens online, by mail, or in person at a DMV office, and you can start the process up to six months before your registration expires.

Connecticut's Department of Motor Vehicles (DMV) sends renewal notices about 45 days before your registration expires. The notice includes your renewal number, which you'll need for any method. You do not have to wait for the notice to arrive — you can renew as soon as six months before the expiration date on your current registration.

The fastest route is the online renewal portal at ct.gov/dmv. You'll need your renewal number, vehicle identification number (VIN), and a valid payment method. The process takes about 10 minutes, and your new registration is mailed within 7 to 10 business days. If you've moved, changed your name, or have outstanding violations or insurance lapses, you may not be able to renew online and will need to visit a DMV office or mail in your renewal.

  • If you've moved, changed your name, or have insurance or violation issues, you must renew by mail or in person at a DMV office.
  • The renewal fee varies by vehicle type and weight; Connecticut charges a base registration fee plus a motor vehicle tax based on the vehicle's value.

What the Connecticut renewal fee covers

Connecticut's registration renewal includes two separate charges: a base registration fee and a motor vehicle tax. The registration fee depends on your vehicle type (passenger car, truck, motorcycle, etc.) and typically ranges from $30 to $60 for standard passenger vehicles. The motor vehicle tax is calculated based on your vehicle's value and is the larger portion of the total cost for most drivers.

The DMV uses the National Automobile Dealers Association (NADA) guide to determine your vehicle's value for tax purposes. A five-year-old sedan might have a motor vehicle tax of $80 to $150, while a newer or more expensive vehicle will cost more. You can estimate your tax before renewing by using the DMV's tax calculator on ct.gov/dmv, which asks for your vehicle's year, make, and model.

If your vehicle is over 20 years old, you may be may be able to access for a reduced registration fee and motor vehicle tax. Vehicles registered as antiques or classics may have access to for this rate. You'll need to explore for antique or classic registration status separately if you haven't already.

Renewing online through the DMV portal

The online renewal process at ct.gov/dmv is the most straightforward option if you're may be able to access. Start by clicking the "Renew Registration" link on the DMV homepage. You'll be asked to enter your renewal number (from the notice), your VIN, and your date of birth. The system will pull up your vehicle information and show you the total renewal cost.

Payment is accepted by credit card, debit card, or electronic check. Once you complete the payment, you'll receive a confirmation number on screen and by email. Your new registration certificate will be mailed to the address on file within 7 to 10 business days. You can continue driving with your current registration until the new one arrives.

If the online system tells you that you cannot renew online, it will usually explain why — common reasons include a lapsed insurance policy, an unpaid violation, or a recent address change that hasn't been processed yet. In those cases, you'll need to resolve the issue first or renew by mail or in person.

Renewing by mail or in person at a DMV office

If you cannot renew online, you can mail your renewal notice and payment to the DMV. The notice itself contains instructions and the mailing address. Include a check or money order for the renewal fee (do not send cash). Mail renewal typically takes 2 to 3 weeks from the time the DMV receives your envelope, plus mail transit time in both directions.

For in-person renewal, visit any Connecticut DMV office with your renewal notice, your current registration, proof of insurance, and a valid ID. Bring a check, money order, or card for payment. You can find office locations and hours at ct.gov/dmv. Walk-in service is available, but wait times vary by location and time of day. Some offices offer appointment scheduling through the website, which can reduce your wait.

In-person renewal is the fastest option if you have a complication — an address change, a name change, or an insurance lapse that needs to be corrected. The DMV staff can often resolve these issues on the spot and issue you a temporary registration while your permanent certificate is mailed.

What happens if your registration expires

Connecticut law requires your registration to be current whenever you drive. If your registration expires and you continue to drive, you can be stopped and fined. The fine for driving with an expired registration is typically $100 to $200, depending on how long it has been expired. A police officer can also issue a citation that requires a court appearance.

If you realize your registration has expired, stop driving the vehicle and renew when ready. You can renew online, by mail, or in person using the same process as a regular renewal. There is no additional penalty fee for renewing late, but you should not operate the vehicle until your new registration is in hand or you have a temporary registration from a DMV office.

If you receive a citation for an expired registration, you can bring proof of renewal to traffic court to show that you have corrected the violation. Many judges will dismiss the citation if you can demonstrate that you renewed promptly after the expiration.

Address changes and other updates during renewal

If you've moved since your last registration, you must update your address with the DMV before or during renewal. Online renewal will not allow you to proceed if your address change hasn't been processed yet. You'll need to update your address separately first, either online at ct.gov/dmv or by visiting a DMV office with proof of your new address (a utility bill or lease agreement works).

The same applies to name changes. If you've married, divorced, or legally changed your name, update it with the DMV before renewing your registration. You'll need to provide a certified copy of the document that shows the change (marriage certificate, divorce decree, or court order). Once the name change is processed, you can renew online or by mail.

If your vehicle's information has changed — for example, you've had major repairs or modifications — you may need to update your vehicle record. Contact your local DMV office to determine whether a new inspection or documentation is required before you renew.

Insurance requirements and registration renewal

Connecticut requires all registered vehicles to carry liability insurance. The DMV checks your insurance status electronically before allowing you to renew. If your policy has lapsed or been cancelled, your online renewal will be blocked, and you'll need to renew in person or by mail after your insurance is reinstated.

When you renew your registration, make sure your insurance company has your correct policy information on file with the state. If you've switched insurance companies, allow a few days for the new policy to appear in the state system before attempting to renew online. If you're having trouble, call your insurance company and ask them to verify that your policy is active and reported to the Connecticut DMV.

If you let your insurance lapse intentionally (for example, because you're selling the vehicle), you should also surrender your registration to avoid fines. You can do this by mailing your registration certificate to the DMV or turning it in at a DMV office.

Frequently Asked Questions

Can I renew my registration if my inspection sticker has expired?

Connecticut does not require a separate vehicle inspection for registration renewal. Your vehicle inspection is handled separately and has its own expiration date. You can renew your registration even if your inspection is expired, but you cannot legally drive the vehicle until the inspection is current. Get your inspection done at any authorized inspection station, then renew your registration.

What if I lose my renewal notice before I renew?

You do not need the physical notice to renew online — you only need your renewal number, which is printed on it. If you've lost the notice, call the DMV at 860-263-5700 and provide your vehicle information. They can give you your renewal number over the phone. Alternatively, you can visit a DMV office and renew in person without the notice.

How long does it take to get my new registration after I renew online?

The DMV mails new registrations within 7 to 10 business days of processing your online renewal. Mail delivery typically adds another 3 to 5 business days, so expect your new certificate to arrive 10 to 15 business days after you complete the online transaction. You can drive legally with your old registration until the new one arrives.

Can I renew my registration if I have an outstanding parking ticket or traffic violation?

Unpaid traffic violations and some parking violations can block your registration renewal. The DMV system will flag your account if there is an outstanding violation. You'll need to pay the violation or resolve it in court before you can renew. Contact the court or municipality where the violation was issued to find out what payment or action is required.

What if I'm selling my vehicle before my registration expires?

You do not need to renew a registration for a vehicle you're selling. Notify the DMV that you've sold the vehicle by submitting a Notice of Sale form, which you can mail or submit online at ct.gov/dmv. This removes your liability for the vehicle once the new owner registers it. If you renew by mistake, you can request a refund from the DMV.
