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

Connecticut's Department of Motor Vehicles (DMV) sends renewal notices about 60 days before your registration expires. You do not have to wait for the notice to arrive — you can renew as soon as your current registration is within six months of expiration. The online renewal system is the fastest route and works for most vehicles; mail and in-person renewal are options if you prefer them or if your vehicle does not may have access to for online renewal.

Your registration renewal fee depends on your vehicle's weight and age. Connecticut charges a flat fee plus a weight-based component. The total typically ranges from around $100 to $200 for most passenger vehicles, though commercial vehicles and those over a certain weight may cost more. You will also pay a $5.50 electronic filing fee if you renew online.

Key Takeaways

  • Connecticut registration renews every two years, and you can start the process up to six months before expiration.
  • Online renewal through the DMV website is the fastest method and works for most standard passenger vehicles.
  • You will need your current registration card, vehicle identification number (VIN), and a valid payment method to renew online.
  • If your vehicle does not may have access to for online renewal, you can renew by mail or visit a DMV office in person.
  • Your new registration card arrives by mail within two weeks of approval; you can print a temporary registration when ready after online renewal.

Renewing online through the Connecticut DMV website

The Connecticut DMV's online renewal system is available at ct.gov/dmv. You will need your current registration card, your vehicle's VIN, and a credit or debit card. The process takes about 10 minutes. After you submit your renewal, the system generates a temporary registration that you can print when ready — this is valid while you wait for your new card to arrive by mail.

Online renewal is not available if your vehicle has a lien, if your registration is suspended, if you have unpaid violations or fines, or if your vehicle requires a safety inspection. You also cannot renew online if your address has changed since your last registration; you will need to update your address first through the DMV website or by visiting an office.

The DMV processes online renewals within one to two business days. Your new registration card is mailed to the address on file and typically arrives within two weeks. During that time, the temporary registration you printed is valid proof of registration.

Renewing by mail

To renew by mail, complete the renewal form that arrives with your notice, or read form J-23 from the DMV website. Include your current registration card, a check or money order for the renewal fee, and mail everything to the address listed on the form. The DMV's mailing address is typically on the renewal notice itself.

Mail renewal takes longer than online renewal — expect two to four weeks for processing, plus mail delivery time in both directions. You do not receive a temporary registration with mail renewal, so your current registration must remain valid until your new card arrives. If your registration expires before the new card reaches you, you are driving without valid registration.

Mail renewal works for vehicles that do not may have access to for online renewal, including those with liens or suspended registrations, though you may need to resolve the suspension first. If you are unsure whether your vehicle qualifies, contact the DMV before mailing your renewal.

Renewing in person at a DMV office

Connecticut has DMV offices in multiple locations throughout the state. You can find the office nearest you and check hours on the DMV website. Bring your current registration card, your vehicle's title or a copy of it, proof of residency (such as a utility bill or lease), and a valid photo ID. Payment can be made by cash, check, or card at most offices.

In-person renewal is useful if you need to update your address, resolve a suspension, or handle a vehicle with a lien. The DMV can often complete these tasks while you wait. Processing time at the office is usually 15 to 30 minutes, and you receive your new registration card before you leave.

Many DMV offices operate on a first-come, first-served basis, though some allow you to reserve a time slot online. Arriving early in the day typically means shorter wait times. If you cannot visit during regular business hours, some offices offer extended hours on certain days.

What happens if your registration expires

Driving with an expired registration in Connecticut is a violation. Police can stop you, and you may receive a fine. If your registration has expired and you have not yet renewed, you should not drive the vehicle on public roads. If you are caught driving with an expired registration, the fine is typically $90 to $130, though the exact amount can vary.

If your registration expired more than 60 days ago, you may need to renew in person at a DMV office rather than online or by mail. The DMV may also require you to pass a safety inspection before renewing a registration that has been expired for an extended period. Contact your local DMV office to confirm what is required in your situation.

Vehicles that require a safety inspection before renewal

Connecticut requires a safety inspection for most vehicles every two years. Your registration renewal and safety inspection are separate processes — you must pass the inspection before you can renew your registration. The inspection covers brakes, lights, wipers, horn, steering, suspension, and emissions (for vehicles subject to emissions testing).

You can have your vehicle inspected at any authorized inspection station in Connecticut. The inspection costs around $20 to $30 and takes about 15 minutes. Once you pass, the inspection station provides you with proof of inspection. You then include this proof when you renew your registration online, by mail, or in person.

If your vehicle fails inspection, you have time to make repairs and return for a re-inspection before your registration expires. Some inspection stations offer re-inspections at a reduced rate if you return within a certain timeframe.

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 as security for a loan — you cannot renew online. You must renew by mail or in person. When you renew, the DMV sends the new registration card to the lienholder's address, not yours. This is standard practice and does not affect your ability to drive the vehicle.

To renew by mail with a lien, include a copy of your loan documents or contact your lender to confirm the address where the DMV should send the registration. If you renew in person, bring proof of the lien (such as a loan statement) and the lienholder's current address. The DMV will update its records and may support the new registration goes to the correct location.

Once you pay off the loan and the lien is released, you can renew online for your next registration cycle. The lienholder will send you a release document; keep this for your records.

Frequently Asked Questions

Can I renew my Connecticut registration if I just moved to the state?

Yes, but you must update your address with the DMV first. If your registration is still valid and your vehicle passed inspection, you can renew online or by mail using your new Connecticut address. If you prefer to handle the address change and renewal together, visit a DMV office in person.

What if I lost my registration card?

You can still renew online or by mail using your VIN and other vehicle information. If you renew online, you will receive a new card by mail. If you need a replacement card before your renewal is due, you can request one at a DMV office or through the website for a small fee.

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

No. When you sell a vehicle, you should notify the DMV and cancel the registration. The new owner will register the vehicle in their name. If you do not cancel the registration, you may receive renewal notices and bills for a vehicle you no longer own.

How much does Connecticut car registration cost?

The renewal fee varies based on your vehicle's weight and age. For most passenger vehicles, expect to pay between $100 and $200 every two years. Commercial vehicles and those over a certain weight cost more. The DMV website has a fee calculator where you can enter your vehicle details to see the exact cost.

Can I renew my registration early?

Yes. You can renew up to six months before your current registration expires. Renewing early does not shorten the two-year validity period — your new registration will still be valid for two years from the expiration date of your current registration, not from the date you renew.
