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

Connecticut requires you to renew your vehicle registration every 24 months. Your renewal notice arrives by mail about 30 days before your registration expires — the expiration date is printed on your registration card and your license plate sticker. You have three ways to renew: online through the Connecticut DMV website, by mail using the renewal notice, or in person at a DMV office. Online renewal is the fastest option and takes about 10 minutes if you have your registration card and a valid payment method.

The renewal fee depends on your vehicle's weight and type. Connecticut charges a base registration fee plus a weight-based fee for most passenger vehicles. The total typically ranges from $120 to $180 for a standard passenger car, but you should check the exact amount on your renewal notice or the DMV website, since fees can change. You'll also need to pay a $5.50 service fee if you renew online or by mail.

Key Takeaways

  • Connecticut registration renews every two years, and your renewal notice arrives 30 days before expiration with the exact fee amount.
  • Online renewal through the Connecticut DMV website is the fastest method and requires only your registration card and a payment method.
  • By-mail renewal uses the notice you receive in the mail and takes 7 to 10 business days after the DMV receives it.
  • In-person renewal at a DMV office requires your registration card, proof of Connecticut residency, and a valid ID, and you leave with your new sticker the same day.
  • If your registration has already expired, you can still renew using any of these methods, but driving with an expired registration is illegal in Connecticut.

Renewing online through the Connecticut DMV website

Online renewal is available at the Connecticut DMV website (ct.gov/dmv) and is the quickest option. You'll need your current registration card, your vehicle identification number (VIN), and a credit or debit card. The process takes about 10 minutes, and you receive a temporary registration confirmation by email when ready. Your new registration card and license plate sticker arrive by mail within 7 to 10 business days.

Online renewal is not available if your vehicle has a lien, if you need to change your address, or if your registration has been suspended. If any of these explore, you must renew by mail or in person. You also cannot renew online if your vehicle failed an emissions test or if you have unpaid parking violations or tolls in Connecticut.

Renewing by mail with your renewal notice

The renewal notice you receive in the mail includes a payment envelope and instructions. You mail back the notice with your payment (check or money order) to the address on the envelope. Do not send cash. Include the $5.50 service fee along with the registration fee shown on your notice.

Mail renewal takes 7 to 10 business days after the DMV receives your payment. To avoid late fees, mail your renewal at least two weeks before your registration expires. Your new registration card and sticker arrive by mail after processing. Keep your renewal notice as proof of timely renewal if your sticker hasn't arrived by your expiration date.

Renewing in person at a Connecticut DMV office

You can renew at any Connecticut DMV office. Bring your current registration card, a valid photo ID (driver's license, passport, or state ID), and proof of Connecticut residency (utility bill, lease, or mortgage statement dated within 60 days). You'll also need to bring payment by check, money order, or debit/credit card. The $5.50 service fee applies in person as well.

In-person renewal takes about 30 minutes to an hour depending on how busy the office is. You leave with your new registration card and license plate sticker the same day. This is the best option if your registration has already expired, if you need to update your address, or if you have questions about your renewal. Connecticut DMV offices are open Monday through Friday, 8:30 a.m. to 4:30 p.m., with some locations open Saturday mornings.

What happens if your registration expires before you renew

Driving with an expired registration is illegal in Connecticut and can result in a fine. If you miss your renewal date, you can still renew using any of the three methods above — expiration does not prevent you from renewing. However, you may face a late fee if you renew more than 30 days after expiration. The late fee amount varies, so check the DMV website or call your local DMV office for the current amount.

If you've been driving on an expired registration and are stopped by police, bring proof that you've already renewed or that you've submitted your renewal. If your registration was expired for more than 60 days, you may need to pass an emissions test before you can renew, depending on your vehicle's age and type.

Emissions testing requirements before renewal

Connecticut requires emissions testing for most vehicles every two years. Your emissions test must be completed before or at the same time as your registration renewal. You can take your vehicle to any Connecticut emissions testing station — they are located throughout the state and are run by private companies. The test costs about $30 to $40 and takes 15 to 20 minutes.

Your vehicle is exempt from emissions testing if it is a new vehicle (less than 4 model years old), a motorcycle, or a vehicle with a gross vehicle weight rating over 10,000 pounds. If your vehicle fails the emissions test, you cannot renew your registration until you fix the problem and pass a retest. Some repair shops offer free or discounted retests after repairs.

Renewing a registration with a lien or loan on the vehicle

If your vehicle has a lien (meaning a bank or lender holds the title), you cannot renew online. You must renew by mail or in person. The lienholder's name appears on your registration card. When you renew, the new registration card and sticker go to the address on file with the DMV, not to the lienholder.

If you've paid off your loan and the lien has been removed, you can renew online starting with your next renewal cycle. If you're unsure whether a lien still exists, check your registration card or contact your lender. You can also call the Connecticut DMV at 860-263-5700 to confirm your vehicle's lien status.

Frequently Asked Questions

Can I renew my Connecticut registration if I've moved out of state?

No. Connecticut registration requires you to be a Connecticut resident. If you've moved out of state, you must register your vehicle in your new state. Contact your new state's DMV for registration requirements. If you still own property in Connecticut and maintain a Connecticut address, you may be able to renew, but you should contact the Connecticut DMV to confirm your residency status.

What if I lost my registration card?

You can still renew by mail or in person. For mail renewal, contact the Connecticut DMV to request a duplicate registration card before you renew, or renew in person at a DMV office with your VIN and ID. For online renewal, you'll need your registration card number, which may be on your license plate sticker or previous correspondence from the DMV.

How do I know if my vehicle needs an emissions test?

Check your registration card — it will show your emissions test expiration date. If that date has passed or is within 30 days, you need a test before renewal. New vehicles (less than 4 model years old) and motorcycles are exempt. You can also check the Connecticut DMV website or call 860-263-5700 to confirm whether your vehicle requires testing.

What if I renew online but my registration card doesn't arrive before my expiration date?

Keep your email confirmation of online renewal. It serves as proof that you renewed on time. You can drive legally on this confirmation until your physical registration card and sticker arrive. If you're stopped by police, show them the email confirmation. If your materials don't arrive within 14 business days, contact the Connecticut DMV to request a replacement.

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

No. Connecticut will not renew your registration if you have unpaid parking violations or tolls. You must pay these fines before you can renew. Contact the municipality where you received the ticket or the Connecticut Toll Collection Center to pay outstanding amounts. Once paid, you can renew online, by mail, or in person.
