Connecticut car registration fees by vehicle type

Connecticut charges registration fees based on the vehicle's weight and type. A standard passenger car costs between $120 and $180 per year, depending on when you register it within the registration year. Motorcycles cost $19 per year. Trucks and commercial vehicles have higher fees that scale with their gross vehicle weight rating (GVWR).

The state also charges a $20 registration fee for all vehicles, plus a $10 agent fee if you register through a DMV agent rather than directly with the state. If your vehicle is financed or leased, your lender or leasing company may require additional documentation, but this does not change the registration fee itself.

Connecticut's registration year runs from the month you first register your vehicle. If you register in March, your renewal will always be due in March. This means the cost you pay depends partly on which month you register — you pay a prorated fee if you register partway through the year.

Key Takeaways

  • Connecticut passenger car registration costs $120 to $180 per year depending on registration month, plus a $20 state fee and $10 agent fee if you use a DMV agent.
  • Motorcycles cost $19 per year; trucks and commercial vehicles cost more based on their gross vehicle weight rating.
  • Your registration year is set by the month you first register, so renewal dates stay the same each year.
  • You can register online, by mail, or in person at a DMV office or authorized agent, and you will need your vehicle's title, proof of insurance, and identification.

What documents you need to register in Connecticut

To register a vehicle in Connecticut, bring or submit the vehicle's title (or a bill of sale if the title has not arrived yet), proof of Connecticut auto insurance, and a valid photo ID. If the vehicle is financed, your lender's name and address must appear on the title. If you are registering someone else's vehicle, you will need a power of attorney or written permission from the owner.

Connecticut requires proof of insurance before the DMV will issue registration. Your insurance company can provide this as a printed card or digital proof. The insurance policy must be active on the date you register — a lapsed policy will delay your registration.

If your vehicle is a salvage title, rebuilt title, or has been declared a total loss by an insurance company, Connecticut requires an inspection before registration. You must schedule this through a DMV-authorized inspection station; the inspection fee is separate from registration and typically costs $50 to $75.

How to register online, by mail, or in person

Connecticut allows online registration renewal for vehicles that already have a current registration. Go to the DMV website, enter your vehicle information and registration number, and pay the fee by credit card or debit card. Online renewal takes about 10 minutes and your new registration should arrive by mail within two weeks.

For a new registration (a vehicle you have never registered in Connecticut), you must register in person at a DMV office or through an authorized agent. DMV offices are located in major cities; authorized agents are often found at insurance agencies, auto repair shops, and town halls. Both charge the same $10 agent fee if you use an agent. Bring all required documents and expect to spend 30 to 45 minutes.

Mail-in registration is available only for renewals. read the renewal form from the DMV website, include a check or money order, and mail it with your current registration card and proof of insurance. Mail processing takes three to four weeks, so submit early if your registration is expiring soon.

Registration fees for commercial and specialty vehicles

Connecticut charges commercial vehicle registration based on the vehicle's gross vehicle weight rating (GVWR), which is the maximum weight the vehicle is designed to carry including cargo. A truck with a GVWR under 4,000 pounds costs about $120 per year; vehicles over 26,000 pounds cost significantly more. The DMV website has a full fee table by weight class.

Vehicles registered as commercial must display a commercial registration plate. If you use a vehicle for both personal and commercial purposes, you may register it as personal and pay the lower fee, but you cannot use it for commercial hauling or delivery without a commercial registration.

Specialty plates — vanity plates, veteran plates, or environmental plates — cost an additional $25 to $50 on top of the standard registration fee. The specialty plate fee is charged each year you renew.

When registration expires and how to renew

Your registration expires on the last day of the month in which you registered the vehicle. If you registered in March, your registration expires on March 31 each year. The DMV mails renewal notices about 30 days before expiration, but you are responsible for renewing on time even if you do not receive the notice.

You can renew online up to 30 days before expiration or up to 30 days after expiration. If you renew after expiration, you are still charged the standard fee — there is no late fee in Connecticut. However, driving with an expired registration is illegal and can result in a traffic ticket.

If you miss the 30-day grace period after expiration, you must register in person at a DMV office or agent. Bring your expired registration card, current proof of insurance, and your vehicle's title or a recent bill of sale.

Additional fees and what they cover

Connecticut charges a $20 registration fee for all vehicles, separate from the weight-based fee. This covers the cost of issuing your registration card and plate. If you need a replacement registration card (your original was lost or damaged), the fee is $5.

If you need a new license plate — because yours was damaged, stolen, or you want a different style — the plate itself costs $10 to $25 depending on the type. Personalized or vanity plates cost $50 for the first year and $25 for each renewal year.

If you change your address, you do not need to pay a fee to update your registration. You can update your address online through the DMV website or by mail. If you sell your vehicle, you must notify the DMV within 10 days; there is no fee for this, but failure to notify can make you liable for parking tickets or violations the new owner incurs.

Frequently Asked Questions

Do I have to register my car every year in Connecticut?

Yes. Connecticut requires annual registration renewal. Your registration expires on the last day of the month you registered, and you must renew before that date or within 30 days after. You can renew online if your registration is current or expired by 30 days or less.

Can I register a vehicle I just bought without a title?

You can register temporarily with a bill of sale while you wait for the title to arrive from the previous owner or the lender. Bring the bill of sale, proof of insurance, and your ID to a DMV office or agent. Once the title arrives, you will need to update your registration, but there is no additional fee.

What happens if I drive with an expired registration?

Driving with an expired registration is illegal in Connecticut and can result in a traffic ticket. You have a 30-day grace period after expiration to renew online or in person. If you are stopped by police, you may receive a fine. Renew as soon as you realize your registration has expired.

Do I pay registration if my car is financed?

Yes. The lender's interest in the vehicle does not change the registration fee. You pay the same amount whether you own the car outright or are financing it. Your lender's name will appear on the title, but this is separate from registration.

Is there a discount for registering multiple vehicles?

Connecticut does not offer a multi-vehicle discount on registration fees. Each vehicle is registered separately and charged the full fee based on its weight and type. You can renew multiple vehicles online in one session, but each registration is charged individually.
