Connecticut car registration renews every two years, and you can renew by mail, online, or in person at a DMV office

Connecticut's Department of Motor Vehicles (DMV) sends renewal notices about 60 days before your registration expires. The notice tells you your renewal fee, which depends on your vehicle's weight and age. You have three ways to renew: mail the completed notice with a check to the DMV, use the online system at ct.gov/dmv, or visit a DMV branch in person. The fastest route is usually online, which takes a few minutes and lets you pay by debit or credit card.

Your registration expires on the last day of the month shown on your current registration card. Driving with an expired registration is illegal in Connecticut, even if you have applied for renewal. If you lose your renewal notice or it arrives damaged, you can request a duplicate by calling the DMV at 860-263-5700 or visiting their website.

Renewing online through the Connecticut DMV website

The Connecticut DMV online renewal system is available at ct.gov/dmv under the "Renew Registration" section. You will need your current registration card, driver's license number, and the last four digits of your vehicle identification number (VIN). The system accepts Visa, Mastercard, American Express, and Discover. Once you complete the transaction, you receive a confirmation number when ready, and your new registration card arrives by mail within 7 to 10 business days.

Online renewal works only if your vehicle information has not changed—no address move, no new owner, no major repairs that altered the vehicle. If anything on your registration has changed, you must renew by mail or in person so the DMV can update your record. The online system will tell you if your situation requires a different method.

Renewing by mail with your notice

Mail renewal is straightforward if you have your renewal notice. Sign the back of the notice where it says "Signature of Registered Owner," write a check for the amount shown, and mail both to the address printed on the notice. Include your current registration card if you want the DMV to update any information. Mail processing takes 2 to 3 weeks, so send your renewal at least three weeks before expiration to avoid driving with an expired registration.

If you are renewing for a vehicle with a lien (a loan against it), the lienholder's name appears on your registration. Some lienholders require notification before renewal; check your loan documents or call your lender to confirm. The DMV does not contact lienholders directly, so it is your responsibility to follow your lender's rules.

Renewing in person at a Connecticut DMV office

Connecticut has DMV branches in Wethersfield, Norwalk, Waterbury, and Norwich. You can walk in during business hours with your renewal notice, current registration card, and a check or card for payment. In-person renewal takes about 15 to 30 minutes depending on how busy the office is. You receive your new registration card on the spot, so you do not have to wait for mail delivery.

In-person renewal is useful if your renewal notice never arrived, if your vehicle information has changed, or if you prefer to handle it face-to-face. DMV offices are open Monday through Friday, 8:30 a.m. to 4:30 p.m., and some locations have extended hours on certain days. Check ct.gov/dmv for your nearest office's exact hours before you go.

What happens if your registration expires before you renew

Driving with an expired registration is a violation in Connecticut. Police can stop you, and you may receive a ticket. If you realize your registration has expired, stop driving the vehicle and renew when ready by any method available. If you are already pulled over, explain that you have submitted your renewal and show the officer your confirmation number or receipt if you renewed online or by mail.

If your registration expired more than a few months ago, the DMV may require you to pass an inspection before renewing. Connecticut requires all vehicles to pass an emissions and safety inspection every two years, and the inspection must be current before you renew. You can find inspection stations at ct.gov/dmv. Schedule the inspection, pass it, and then renew your registration.

Renewal fees and what they cover

Connecticut's renewal fee is based on your vehicle's gross weight rating (the maximum weight it can safely carry, including passengers and cargo). Heavier vehicles pay more. Your renewal notice shows your specific fee. As of recent years, fees range from around $60 for lighter vehicles to over $200 for trucks and large vehicles, but the exact amount depends on your vehicle's specifications and any applicable discounts.

The renewal fee covers your registration for two years. Some vehicles may may have access to for a reduced fee—for example, vehicles owned by disabled veterans or certain nonprofit organizations. If you believe you may have access to for a discount, mention it when you renew in person, or call the DMV before mailing your payment to confirm the correct amount.

Renewing a vehicle with a different address or owner

If you moved to a new address in Connecticut, update your address before renewing. You can do this by mail, phone, or in person at a DMV office. The DMV will send your renewal notice to your new address. If you did not update your address and your notice went to your old home, call 860-263-5700 to request a duplicate notice mailed to your current address.

If the vehicle has a new owner—for example, you inherited it or bought it from someone else—the original owner must transfer the title to you first. This is a separate transaction from registration renewal. Once the title is in your name, you can renew the registration. If you are unsure whether the title is in your name, check your registration card; it lists the registered owner.

Frequently Asked Questions

Can I renew my Connecticut registration if my inspection is expired?

No. Connecticut requires a current inspection before renewal. Schedule an inspection at any approved station, pass it, and then renew your registration. If your inspection expired more than a few months ago, you may need to renew it before the DMV will process your registration renewal.

What if I lost my renewal notice?

Call the DMV at 860-263-5700 and request a duplicate notice. You can also renew in person at any DMV office with your current registration card and driver's license. Online renewal is not available without your notice, but mail and in-person renewal are.

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

Online and mail renewals take 7 to 10 business days for the card to arrive. In-person renewal is when ready—you receive your new card the same day. If you need to drive before the card arrives, your confirmation number or receipt serves as proof of renewal.

Do I have to renew in person if I moved out of state?

No. You can renew by mail or online from anywhere. However, if you moved out of Connecticut permanently, you should transfer your registration to your new state rather than renew in Connecticut. Contact your new state's DMV for instructions.

What if my vehicle's weight or type changed?

If you made major modifications—for example, added a commercial truck bed—your vehicle's classification may have changed, which affects your renewal fee. Renew in person or by mail so the DMV can update your vehicle information. Do not use online renewal if anything about your vehicle has changed.
