Renew your Connecticut car registration online, by mail, or in person at a DMV office

Connecticut sends renewal notices 60 days before your registration expires. You can renew online through the DMV website if your vehicle has a valid inspection and you have no outstanding violations or fees. If you cannot renew online, you can mail your renewal notice with payment to the DMV, or visit a DMV office in person. The online route takes minutes; mail takes one to two weeks; in-person visits typically take 30 to 45 minutes depending on wait times.

Your registration renewal is separate from your vehicle inspection. Connecticut requires an inspection every two years, and you must have a current 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 inspected first.

Key Takeaways

  • Online renewal through the Connecticut DMV website is the fastest option and works if your inspection is current and you have no outstanding violations.
  • You will receive a renewal notice in the mail about 60 days before your registration expires; keep this notice because you will need the confirmation number to renew online.
  • Mail renewal takes one to two weeks and requires you to send your renewal notice and payment to the DMV address listed on the notice.
  • Your vehicle inspection must be current before you renew; if it expires before your new registration takes effect, schedule an inspection at a licensed station first.
  • Registration renewal fees vary based on your vehicle type and weight; the DMV notice you receive will show the exact amount due.

Renewing online through the Connecticut DMV website

Online renewal is available at ct.gov/dmv under the "Renew Registration" option. You will need your renewal notice (which arrives in the mail), your vehicle identification number (VIN), and a payment method — credit card, debit card, or electronic check. The system will ask you to confirm your vehicle information and inspection status before processing payment.

Online renewal works only if your inspection is valid through the date your new registration takes effect. If your inspection expires before that date, the system will not allow you to complete the transaction online. In that case, you must either get your vehicle inspected first or use mail or in-person renewal instead.

After you submit payment online, you receive a confirmation number when ready. Your new registration documents will arrive by mail within 7 to 10 business days. You can drive legally on your old registration until the new one arrives, as long as you have the confirmation number with you.

Renewing by mail

Mail renewal requires you to send your renewal notice, a check or money order for the renewal fee, and a completed form (if required for your situation) to the DMV address printed on your renewal notice. Do not send cash. Include a return envelope with postage if you want your new registration mailed back to you faster, though the DMV will mail it regardless.

Processing time for mail renewal is typically one to two weeks from the date the DMV receives your envelope. To avoid a gap in your registration, mail your renewal at least three weeks before your current registration expires. If you are cutting it close, in-person renewal is faster and more reliable.

Keep a copy of what you mail for your records. If your renewal notice included a postage-paid return envelope, use it; otherwise, include proper postage on your return envelope or the DMV will not send your new registration back.

Renewing in person at a DMV office

Connecticut has DMV offices in multiple locations. You can find the nearest office and current wait times at ct.gov/dmv under "Office Locations." Bring your renewal notice, your vehicle's current registration, your driver's license or state ID, and payment (cash, check, debit card, or credit card — accepted methods vary by location, so call ahead if you are unsure).

In-person renewal is the fastest option if you need your new registration when ready. You will receive temporary registration documents on the spot, and your permanent registration card will arrive by mail within 7 to 10 business days. Wait times vary by location and time of day; visiting early in the morning or mid-week typically means shorter lines.

If you do not have your renewal notice, bring your VIN and proof of vehicle ownership (title, previous registration, or insurance card). The DMV staff can look up your renewal information if you provide your vehicle details and driver's license.

What to do if your inspection has expired

Your vehicle inspection must be current before you can renew your registration. If your inspection has expired or will expire before your new registration takes effect, you must get a new inspection at a licensed inspection station before you renew. Inspection stations are independent businesses — gas stations, repair shops, and dedicated inspection centers — not DMV offices.

An inspection costs between $15 and $20 and takes 15 to 30 minutes. After inspection, you receive a sticker to place on your windshield and an inspection certificate. Bring this certificate with you if you renew in person, or have the inspection station number available if you renew online (the DMV system can verify current inspections).

If you attempt to renew online and your inspection status does not show as current, the system will tell you before you pay. In that case, get inspected first, wait for the inspection to appear in the DMV system (usually within 24 hours), and then renew online.

Understanding renewal fees and what affects the cost

Connecticut registration renewal fees depend on your vehicle's type, weight, and age. The renewal notice you receive in the mail shows the exact fee you owe. Fees typically range from $60 to $150 for standard passenger vehicles, but commercial vehicles, trailers, and specialty vehicles have different rates.

If you have unpaid parking tickets, toll violations, or other outstanding DMV-related fees, your renewal notice will reflect those amounts added to your registration fee. You must pay all outstanding amounts before your registration can be renewed. If you are unsure whether you have outstanding fees, call the DMV at the number on your renewal notice or check your account at ct.gov/dmv.

Some vehicle owners may have access to for fee reductions or exemptions — for example, disabled veterans or certain nonprofit organizations. If you think you may may have access to, contact the DMV before renewing to confirm your status and receive the correct fee.

What happens if your registration expires before you renew

Driving with an expired registration is illegal in Connecticut. If you are pulled over, you face a fine and possible vehicle impoundment. If your registration has already expired, renew it when ready using any of the three methods above. You can renew an expired registration online, by mail, or in person; there is no separate process for late renewal.

If your registration expired more than a few months ago, contact the DMV to confirm there are no additional penalties or holds on your vehicle before you renew. In most cases, you straightforward pay the renewal fee and any late fees that may explore, and your registration is restored.

To avoid expiration, mark your renewal important date on your calendar when you receive the renewal notice. The notice arrives 60 days before expiration, giving you plenty of time to renew through any method you choose.

Frequently Asked Questions

Can I renew my registration if I just bought a used car in Connecticut?

No, you cannot use the renewal process for a newly purchased vehicle. You must first register the vehicle in your name at a DMV office or by mail using the title and bill of sale. Once that registration is complete, you will receive renewal notices for future years. If you bought the car close to when the previous owner's registration was set to expire, you may need to renew sooner than expected.

What if I lost my renewal notice?

You can still renew online or in person without the notice. Online, you will need your VIN and driver's license to look up your renewal information. In person, bring your current registration, driver's license, and VIN. The DMV staff can retrieve your renewal details and process your renewal on the spot. You can also call the DMV to request a replacement notice be mailed to you, though this adds time.

Do I need to renew my inspection at the same time as my registration?

No, inspections and registrations are separate. Your inspection is valid for two years from the date you get it; your registration is valid for one or two years depending on your vehicle type. You may need to get inspected and renew your registration in different months. Just make sure your inspection is current whenever you renew your registration.

How long can I drive on my old registration after I renew online?

You can drive on your old registration until your new one arrives in the mail, as long as you have your online confirmation number with you. The new registration typically arrives within 7 to 10 business days. If you are stopped by police, show them your old registration and your confirmation number as proof that you have renewed.

What if my address changed since my last registration?

Update your address with the DMV before renewing. You can change your address online at ct.gov/dmv, by mail, or in person at a DMV office. Once your address is updated, your renewal notice will be mailed to your new address. If you already received a renewal notice at your old address, you can still use it to renew, but update your address at the same time to may support future notices go to the correct location.
