How to cancel your Connecticut vehicle registration
You can cancel your Connecticut vehicle registration by mail, in person at a DMV branch, or online through the Connecticut DMV portal. The fastest method is online if you have your registration card and know your vehicle identification number (VIN). By mail, send your registration card and a signed letter stating you want to cancel to the Connecticut DMV. In person, bring your registration card to any DMV office and ask to cancel — staff will process it on the spot.
Connecticut does not charge a fee to cancel registration. You do not need to provide a reason. The cancellation takes effect when ready when processed, though you may receive a confirmation letter in the mail within one to two weeks.
If your vehicle is financed or leased, contact your lender or leasing company before canceling. They may hold the title and need to approve the cancellation. If you are selling the vehicle, the new owner will need to register it in their name — canceling your registration does not transfer it.

- If your vehicle is financed or leased, contact your lender before canceling because they may need to approve it.
- Cancellation takes effect when ready, though a confirmation letter may arrive one to two weeks later.

Canceling online through the Connecticut DMV portal
The Connecticut DMV online portal lets you cancel registration without visiting an office. Go to ct.gov/dmv and log in with your ConneCT account. If you do not have one, you can create it using your driver's license number and date of birth. Select the vehicle you want to cancel and follow the prompts to confirm the cancellation.
You will need your registration card in front of you because the system asks for your registration number and VIN. After you submit, the cancellation processes when ready and you receive an on-screen confirmation. Print or save this confirmation for your records. A formal cancellation letter arrives by mail within one to two weeks.
If you cannot access the online portal or your vehicle does not appear in the system, use the mail or in-person method instead. Technical issues are rare, but the DMV phone line at 860-263-5700 can help you troubleshoot.
Canceling by mail
To cancel by mail, write a short letter on plain paper stating that you want to cancel the registration for your vehicle. Include your name, address, the vehicle's VIN, the license plate number, and the registration number (all on your registration card). Sign and date the letter, then enclose your registration card.
Mail the letter and card to:
Connecticut Department of Motor Vehicles Registration Section 60 State Street Wethersfield, CT 06161
Processing takes two to four weeks from the date the DMV receives your letter. Keep a copy of your letter for your records. If you need proof of cancellation before the confirmation letter arrives, call the DMV at 860-263-5700 with your registration number and they can verify the status.
Canceling in person at a DMV branch
Visit any Connecticut DMV branch office with your registration card. Tell the staff member you want to cancel your registration. They will take your card, process the cancellation, and give you a receipt on the spot. This is the fastest method if you need when ready proof of cancellation.
Connecticut DMV branches are located in Wethersfield, Waterbury, Norwalk, and New Britain. Hours vary by location, so check ct.gov/dmv for the branch nearest you and confirm hours before you go. You do not need an appointment for registration cancellations.
Bring your registration card and a photo ID. If someone else is canceling on your behalf, they will need a signed letter from you authorizing them to do so, plus both their ID and your registration card.
What happens to your license plate after cancellation
Your license plate remains your property after you cancel registration. You can keep it, destroy it, or turn it in to the DMV. If you plan to register another vehicle soon, keeping the plate is optional — the new vehicle will receive a new plate.
If you want to turn in your plate, bring it to any DMV branch. If you want to destroy it, you can do so at home — there is no requirement to return it. Some people keep old plates as keepsakes or for display.
Do not use the plate on another vehicle or give it to someone else to use. Once your registration is canceled, the plate is no longer valid for road use.
Canceling when you sell or transfer your vehicle
When you sell your vehicle in Connecticut, you are responsible for canceling your registration. The buyer does not automatically inherit your registration — they must register the vehicle in their own name. If you do not cancel, you remain the registered owner and liable for any violations or unpaid tolls on that vehicle.
Cancel your registration as soon as the sale is complete. You can do this online, by mail, or in person using the same methods described above. The buyer will need to bring the signed title and bill of sale to a DMV branch to register the vehicle in their name. They cannot register it until you have canceled yours.
If you are trading in a vehicle at a dealership, ask the dealer whether they will handle the cancellation or whether you need to do it yourself. Most dealerships cancel the registration as part of the trade-in process, but confirm this in writing before you leave.
Canceling a registration for a vehicle you no longer own
If your vehicle was totaled, scrapped, or stolen, cancel the registration to avoid liability. For a totaled or scrapped vehicle, contact your insurance company — they may handle the cancellation notification to the DMV. For a stolen vehicle, file a police report first, then cancel the registration by mail or in person. Bring a copy of the police report if you cancel in person.
If the vehicle was sold but you did not cancel the registration yourself, contact the DMV when ready. Explain that you are no longer the owner and provide the buyer's name and contact information if you have it. The DMV can investigate and remove you as the registered owner, though this process takes longer than a standard cancellation.
Do not ignore an unpaid toll notice or violation ticket for a vehicle you no longer own. Contact the issuing agency with proof that you are no longer the owner (such as a bill of sale or police report for theft) and ask them to update their records.
Frequently Asked Questions
Do I get a refund if I cancel my registration mid-year?
Connecticut does not refund registration fees for mid-year cancellations. Your registration fee covers the full year regardless of when you cancel. If you cancel in January, you do not recover the unused months.
Can I cancel my registration if I have unpaid tolls or parking tickets?
Yes, you can cancel your registration even with unpaid tolls or tickets. However, canceling does not erase the debt. The DMV will still pursue collection, and you may face license suspension or other penalties. Settle outstanding violations before canceling if possible.
What if I lose my registration card before I cancel?
You can still cancel by mail or in person without the card. By mail, include your VIN, license plate number, and registration number (if you know it) in your letter. In person, bring your driver's license and vehicle title or bill of sale to prove ownership. The DMV can look up your registration using your VIN.
How long does it take to cancel a registration?
Online cancellation is when ready. In-person cancellation takes minutes. By mail, allow two to four weeks from the date the DMV receives your letter. You receive a confirmation letter within one to two weeks of processing.
Do I need to cancel my registration if I move out of Connecticut?
Yes. If you move to another state, cancel your Connecticut registration and register your vehicle in your new state. You cannot legally drive with an out-of-state registration in Connecticut, and Connecticut cannot legally register a vehicle for someone who no longer lives there.
