Where to Renew Your Connecticut Vehicle Registration

You can renew your Connecticut vehicle registration through the DMV website, by mail, or in person at a DMV branch. The online method is fastest — you can complete it in minutes from home and pay by credit card. Mail renewal takes about two weeks once the DMV receives your form. In-person renewal at a DMV office is when ready if you bring all required documents, but you will wait in line.

The DMV website at ct.gov/dmv is the starting point for all three methods. You will need your current registration card, vehicle identification number (VIN), and a valid payment method. If you renew online, your new registration arrives by mail within five to seven business days.

Key Takeaways

  • Connecticut allows online renewal through ct.gov/dmv, which is the fastest option and takes five to seven business days for your new registration to arrive.
  • You must renew before your registration expiration date or you cannot legally drive the vehicle, and late renewal carries a penalty fee.
  • Your current registration card, vehicle VIN, and proof of a passing emissions test (if your vehicle requires one) are the documents you will need.
  • If your vehicle failed emissions or you have unpaid parking tickets, the DMV will not process your renewal until those issues are resolved.

Renewing Online Through the DMV Website

Go to ct.gov/dmv and select the vehicle registration renewal option. You will enter your vehicle identification number, current registration number, and the last four digits of your Social Security number or federal employer identification number. The system will pull up your vehicle record and show you the renewal fee, which varies based on your vehicle type and weight.

Once you confirm the information is correct, you pay by credit card or debit card. The DMV sends a confirmation email when ready. Your new registration card arrives in the mail within five to seven business days. You do not need to visit an office or mail anything in — the entire process happens online.

Online renewal works only if your vehicle has a passing emissions test on file (if Connecticut requires one for your vehicle type and model year) and you have no outstanding parking violations or other holds on your registration. If the system tells you that you cannot renew online, you will need to visit a DMV office or call 860-263-5700 to find out why.

Renewing by Mail

Request a renewal form by calling the DMV at 860-263-5700 or read the form from ct.gov/dmv. Fill out the form completely, including your vehicle VIN, current registration number, and odometer reading. Include a check or money order for the renewal fee made payable to the State of Connecticut.

Mail the completed form and payment to the address listed on the form. The DMV processes mail renewals in the order they are received. Processing takes about two weeks from the date the DMV receives your envelope, though it may take longer during busy periods. Your new registration card arrives by mail after processing is complete.

Keep a copy of what you mail in case the DMV does not receive it. If your registration expires before your renewal arrives, you are driving without a valid registration. Mail renewal is slower than online renewal and should be used only if you cannot renew online or in person.

Renewing in Person at a DMV Office

Bring your current registration card, vehicle VIN, proof of a passing emissions test (if required), and a valid photo ID to any DMV branch. You can find office locations and hours at ct.gov/dmv. Some offices accept walk-ins; others require an appointment. Check the website or call ahead to confirm whether your local office takes appointments or operates on a first-come, first-served basis.

When you arrive, take a number and wait to be called. Tell the clerk you are renewing your registration. The clerk will verify your information, confirm your emissions status, and collect payment. You pay by cash, check, or card. The DMV prints your new registration card on the spot, and you leave with it in hand.

In-person renewal takes about 30 minutes to an hour depending on how busy the office is. This method is useful if you need your registration when ready or if you cannot renew online because of a hold or emissions issue that you can resolve in person.

Emissions Testing Requirements

Connecticut requires emissions testing for most gasoline-powered vehicles that are at least two model years old. Diesel vehicles and vehicles registered as antiques are exempt. Your vehicle must have a passing emissions test on file with the DMV before you can renew your registration.

If your vehicle has never been tested or your previous test expired, you must visit a Connecticut emissions testing station before you renew. The test costs money and takes about 15 minutes. Once you pass, the testing station sends the results to the DMV electronically. You can then renew online or in person.

If your vehicle failed the emissions test, you must have it repaired and tested again at a different station. The DMV will not process your renewal until a passing test is on file. Some repair shops offer free or reduced-cost repairs for emissions failures; the testing station can provide a list of participating shops in your area.

Renewal Fees and Payment Methods

Connecticut registration renewal fees depend on your vehicle's gross vehicle weight rating (GVWR) and type. Passenger cars typically cost between $120 and $150 for a two-year registration. Motorcycles, trucks, and specialty vehicles have different fee schedules. The DMV website shows the exact fee for your vehicle before you pay.

You can pay by cash, check, money order, or credit card. Online renewal accepts credit and debit cards only. In-person renewal accepts all methods. Mail renewal requires a check or money order. If you pay by check or money order and it bounces, the DMV will contact you and may charge a returned-check fee in addition to the renewal fee.

If you renew after your registration expires, Connecticut charges a late penalty fee on top of the standard renewal fee. The penalty increases the longer you wait. Renewing before your expiration date avoids this extra cost.

What Happens If Your Registration Expires

Driving with an expired registration is illegal in Connecticut. If you are stopped by police, you can receive a ticket and fine. Your vehicle may also be towed if the registration is significantly overdue. Insurance companies may also deny claims if you are in an accident while driving with an expired registration.

If your registration has expired, you can still renew it through any of the three methods described above. The DMV will add a late penalty fee to your renewal cost. The sooner you renew, the lower the penalty. You should not drive the vehicle on public roads until your registration is current.

If you cannot renew when ready, you can request a temporary registration permit from the DMV to drive to an emissions testing station or repair facility. Call 860-263-5700 to request a temporary permit. The permit is valid for a limited time and is not a substitute for full registration renewal.

Frequently Asked Questions

Can I renew my registration if I have unpaid parking tickets?

No. The DMV will not process your renewal if you have outstanding parking violations in Connecticut. You must pay the tickets first. Contact the municipality where you received the ticket to pay or set up a payment plan. Once the tickets are paid, you can renew online, by mail, or in person.

How long is a Connecticut vehicle registration valid?

Connecticut vehicle registrations are valid for two years from the date of issue. Your expiration date is printed on your registration card. You should renew before that date to avoid driving with an expired registration and incurring a late penalty.

What if I moved and my address on the registration is wrong?

You must update your address with the DMV before or during renewal. If you renew online, you can update your address in the same transaction. If you renew by mail or in person, bring proof of your new address, such as a utility bill or lease. The DMV will update your record and issue a new registration card with the correct address.

Can I renew my registration if my vehicle is financed or leased?

Yes. Whether you own, finance, or lease your vehicle, you renew the registration the same way. If your vehicle is financed or leased, the lienholder or lessor may be listed on your registration. This does not change the renewal process. Bring your current registration card and follow the steps for your chosen renewal method.

What if the DMV website says I cannot renew online?

The system blocks online renewal if your vehicle has a failed emissions test, unpaid parking tickets, or another hold on your account. Call the DMV at 860-263-5700 to find out what the issue is. You can usually resolve it by paying tickets, getting your vehicle tested, or providing missing information. Once resolved, you can renew online or in person.
