Connecticut registration renewal happens online, by mail, or in person at a DMV office

Connecticut allows you to renew your vehicle registration through three routes: the online system at ct.gov/dmv, by mail using the renewal notice you receive, or by visiting a DMV branch in person. Most people renew online because it takes about 10 minutes and you can do it from home. The state sends renewal notices 60 days before your registration expires, and you can renew up to 6 months early if you want to avoid the rush.

Your registration renewal is separate from your vehicle inspection. Connecticut requires an inspection every two years, and you must have a valid inspection before you can renew your registration. If your inspection has expired or will expire before your new registration takes effect, you need to get that done first at any state-approved inspection station.

Key Takeaways

  • You can renew online at ct.gov/dmv in about 10 minutes using your renewal notice or vehicle identification number.
  • Your vehicle must have a current inspection before you renew registration; if it expired, schedule an inspection at any approved station before you proceed.
  • The state mails renewal notices 60 days before expiration, and you can renew up to 6 months early to avoid waiting in line.
  • Renewal fees vary based on vehicle weight and type; the state website shows your exact fee when you start the online process.
  • If you miss the expiration date, you can still renew, but you may face a late fee and cannot legally drive until the new registration is active.

Renewing online through the Connecticut DMV website

Go to ct.gov/dmv and select the vehicle registration renewal option. You will need either your renewal notice (the paper form the state mailed you) or your vehicle identification number (VIN). The system will ask for your driver's license number, vehicle information, and current mailing address. Review the fee amount — it appears on screen before you pay — and complete payment by credit card, debit card, or electronic check.

After you pay, the system generates a temporary registration that is valid when ready for 30 days while your permanent registration is being processed and mailed. Print this temporary registration and keep it in your vehicle. Your permanent registration arrives by mail within 7 to 10 business days in most cases. If you do not receive it within two weeks, contact the DMV at 860-263-5700 to check the status.

Renewing by mail with your renewal notice

The renewal notice the state mails you includes a payment envelope and instructions. Fill out the form, include a check or money order for the renewal fee (the notice shows the amount), and mail it to the address on the envelope. Mail renewal takes longer than online — typically 2 to 3 weeks from the time the DMV receives it — so send it at least 4 weeks before your registration expires if you want to avoid driving with an expired registration.

You can also mail in your renewal if you lost your online renewal notice. Call the DMV at 860-263-5700 and request a replacement notice, or visit a DMV office to pick one up. The mailed registration is valid only after the DMV processes it and mails it back to you, so you cannot drive legally during the processing period if your current registration has expired.

Renewing in person at a Connecticut DMV office

Visit any DMV branch with your current registration, proof of inspection, and a valid ID. Bring a check, money order, or credit/debit card to pay the renewal fee. In-person renewal is fastest if you need your new registration the same day — the DMV can issue a temporary registration on the spot that is valid for 30 days while your permanent registration is mailed.

DMV offices are open Monday through Friday, 8:30 a.m. to 4:30 p.m., and some branches have extended hours on certain days. Wait times vary by location and time of day. You can check current wait times and find the nearest office at ct.gov/dmv before you go. Bring all documents with you; if your inspection is expired, you cannot complete the renewal at the DMV office and must get an inspection first.

What happens if your registration expires

Driving with an expired registration is illegal in Connecticut. If you are stopped by police, you face a fine and the vehicle can be cited. Your insurance may also deny a claim if you were in an accident while driving with expired registration, depending on your policy language.

If your registration has already expired, you can still renew it using any of the three methods above. However, you may owe a late fee in addition to the standard renewal fee. The amount varies, so check the fee when you renew online or call 860-263-5700 to confirm the total cost before you pay. Once you renew, your new registration is valid from the date the DMV processes it, not from the date your old one expired.

Registration fees and what affects the cost

Connecticut registration renewal fees depend on your vehicle's gross vehicle weight rating (GVWR), not the actual weight. Passenger cars typically cost less to renew than trucks or SUVs. The state website shows your exact fee when you start the online renewal process, so you know the cost before you pay.

Some vehicles may have access to for reduced fees or exemptions. Electric vehicles, for example, may have different fee structures. If you have questions about your specific fee, the DMV website lists fee schedules by vehicle type, or you can call 860-263-5700 to ask.

Inspection requirements before renewal

Connecticut requires a vehicle inspection every two years. Your inspection sticker shows the expiration month and year. Before you renew your registration, check that your inspection is current. If it expires before or on the same date as your registration, you must get a new inspection first.

Schedule an inspection at any state-approved inspection station — these are typically repair shops, tire shops, and service stations throughout Connecticut. The inspection takes about 15 minutes and costs a set fee (currently $20 for most vehicles, though this can change). Once you pass, the station issues an inspection sticker valid for two years. After you have a current inspection, you can renew your registration online, by mail, or in person.

Frequently Asked Questions

Can I renew my registration if my inspection expired?

No. You must have a current inspection before the DMV will process a registration renewal. Schedule an inspection at any approved station first, then renew your registration. If you try to renew online or by mail without a current inspection, the system will reject your request.

How long does a temporary registration last?

A temporary registration issued online or in person is valid for 30 days. During that time, your permanent registration is being processed and mailed to you. Keep the temporary registration printed and in your vehicle. If your permanent registration does not arrive within 14 days, contact the DMV to check the status.

What if I moved and my renewal notice went to my old address?

Call the DMV at 860-263-5700 and update your address on file. Request a replacement renewal notice be mailed to your new address, or renew online using your VIN instead of the notice. You can also visit a DMV office in person with proof of your new address to renew when ready.

Can I renew my registration if it expired more than a year ago?

Yes, but you will owe late fees in addition to the renewal fee. Your vehicle cannot be legally driven until the renewal is processed. Contact the DMV at 860-263-5700 to confirm the total cost, including late fees, before you renew.

Do I need to renew my registration if I sold my vehicle?

No. When you sell a vehicle, you should notify the DMV and surrender the registration plates. The new owner is responsible for registering the vehicle in their name. Contact the DMV or visit ct.gov/dmv for instructions on transferring ownership.
