What Connecticut charges to register a car
Connecticut's registration fee depends on your vehicle's weight and age. A passenger car typically costs between $120 and $180 per year, but the exact amount varies based on the vehicle's gross vehicle weight rating (GVWR) — the maximum weight it can safely carry, including cargo and passengers. Older vehicles and lighter cars fall at the lower end; heavier or newer vehicles cost more.
You'll also pay a $20 registration processing fee on top of the base registration fee. If you're registering a vehicle for the first time in Connecticut, you may owe additional fees for the title process. The Connecticut Department of Motor Vehicles (DMV) charges $75 for a new title when you register an out-of-state vehicle or a newly purchased car in the state.
Registration is valid for one year from the date you receive your plates. When you renew, you'll pay the same registration and processing fees again. If your vehicle's weight class changes — for example, if you add a commercial use designation — your fee may change at renewal.

How Connecticut calculates your registration fee by vehicle weight
The DMV assigns your vehicle to a weight class based on its GVWR, which you can find on the driver's side door jamb or in your owner's manual. Most sedans and compact cars fall into the 3,500 to 4,500-pound range and pay the lower registration rates. Larger SUVs, trucks, and vans may fall into higher weight classes and pay more.
Connecticut publishes a fee schedule that lists the exact registration cost for each weight class. The schedule is updated annually and is available on the DMV website. If you're unsure which class your vehicle falls into, you can call the DMV at 860-263-5700 or visit a local DMV office with your vehicle's documentation, and staff can tell you the exact fee before you pay.
What you pay when you first register a vehicle in Connecticut
If you're registering a vehicle in Connecticut for the first time — whether it's new, used, or transferred from another state — you'll pay the annual registration fee plus the $20 processing fee plus a $75 title fee. The title fee is a one-time charge; you won't pay it again at renewal.
You'll also need to provide proof of ownership (the title or bill of sale), proof of Connecticut residency, and proof of insurance. Connecticut requires all registered vehicles to carry liability insurance before you can legally drive. Bring these documents to a DMV office or mail them with your registration form if you're registering by mail.
If you're transferring a title from another state, Connecticut may charge a transfer fee in addition to the new title fee. The total cost for a first-time registration typically ranges from $215 to $275, depending on your vehicle's weight class.
Registration renewal costs and timing
When you renew your registration, you pay only the annual registration fee and the $20 processing fee — no title fee. The DMV sends renewal notices 30 to 45 days before your registration expires. You can renew online, by mail, or in person at a DMV office.
Online renewal is the fastest option and costs the same as renewing in person or by mail. You'll need your current registration card and a valid payment method. The DMV processes online renewals within one business day, and your new registration is valid when ready.
If you renew by mail, allow at least two weeks for processing. If you renew in person, you'll receive your new plates and registration card the same day. Renewing late carries a penalty: Connecticut charges a $25 late fee if you renew more than 30 days after your registration expires.
Additional fees for special vehicle types
Motorcycles in Connecticut pay a lower registration fee than passenger cars — typically $60 to $80 annually, plus the $20 processing fee. Trailers have their own fee structure based on weight and type; utility trailers usually cost $35 to $50 per year.
Commercial vehicles registered for business use may pay higher fees or fall into different weight classes than the same vehicle registered for personal use. If you use your vehicle for rideshare, delivery, or other commercial purposes, you may need a commercial registration, which has a different fee. Contact the DMV to determine whether your use requires a commercial registration.
Vehicles registered as antiques or classics may may have access to for reduced registration fees. Connecticut offers antique vehicle registration for cars at least 20 years old that are maintained in original or restored condition and driven only for exhibition or club activities. The fee is typically lower than standard registration.
How to pay your registration fee
You can pay your registration fee in person at any Connecticut DMV office, by mail, or online through the DMV website. Online payment is the fastest method and accepts credit cards and debit cards. By mail, you can send a check or money order along with your registration form and required documents to the address listed on the DMV website.
In-person payment accepts cash, check, debit card, and credit card. If you're paying in person, bring your current registration, proof of insurance, and a valid ID. The DMV office will process your payment and issue new plates and a registration card on the spot if you're renewing; first-time registrations may take longer if documents need to be verified.
If you pay online and your registration is not yet due for renewal, you can pay early. The DMV will process your payment and your new registration will be valid from the date you pay, extending your registration period by one year from that date.
What happens if you don't renew on time
Driving with an expired registration in Connecticut is illegal and can result in a traffic ticket. Police can stop you for expired plates, and you may face a fine of $100 to $500 depending on how long your registration has been expired. If you're pulled over, you'll also be required to show proof of current registration before you can legally continue driving.
If your registration expires and you continue to drive, you also lose liability insurance coverage in most cases — your insurer may cancel your policy if your vehicle is not registered. This creates a legal and financial risk if you're involved in an accident.
If you miss your renewal important date, you can still renew at any time. The DMV will not charge you a penalty fee if you renew within 30 days of expiration, but you will owe the $25 late fee if you renew more than 30 days after expiration. You cannot legally drive until your registration is current.
Frequently Asked Questions
Can I register my car online in Connecticut?
Yes, you can renew an existing registration online through the DMV website. However, you cannot complete a first-time registration online; you must visit a DMV office or mail in your documents for new registrations. Online renewal takes about one business day to process.
What if I don't know my vehicle's weight class?
Check your vehicle's door jamb label or owner's manual for the GVWR. You can also call the DMV at 860-263-5700 with your vehicle's year, make, and model, and staff can tell you the weight class and exact fee. Bringing your vehicle to a DMV office is another option.
Do I have to renew my registration on my birthday?
No. Your registration renews on the anniversary of the date you first registered the vehicle in Connecticut, not on your birthday or a calendar date. The DMV sends a renewal notice 30 to 45 days before your registration expires, which tells you the exact due date.
Is there a discount if I register multiple vehicles?
Connecticut does not offer a multi-vehicle discount on registration fees. Each vehicle is registered separately and pays the full fee based on its weight class. You can renew multiple vehicles at the same time online or in person, but the fee for each vehicle is calculated individually.
What if I sell my car before my registration expires?
You do not receive a refund for unused registration time. Once you sell the vehicle, the new owner must register it in their name. If the new owner is in Connecticut, they'll pay a new registration fee. You should notify the DMV of the sale to remove yourself from liability for the vehicle.
