Connecticut registration fees depend on your vehicle's weight and age

Connecticut charges registration fees based on your car's gross vehicle weight rating (GVWR)—the maximum weight it can safely carry—not what it actually weighs. The fee ranges from $120 to $340 per year for most passenger vehicles. Older vehicles (model year 1995 and earlier) pay a flat $120 fee regardless of weight. Newer vehicles in the lightest weight class start at $120, and fees increase as weight increases.

You'll also pay a $10 registration processing fee on top of the weight-based 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) website lists the exact fee schedule by weight class, which you can check before you register.

Registration is valid for one or two years depending on what you choose at registration. A one-year registration costs less upfront but requires you to renew sooner. A two-year registration costs more but covers two years of driving without renewal.

Key Takeaways

  • Connecticut registration fees range from $120 to $340 per year based on your vehicle's gross vehicle weight rating, plus a $10 processing fee.
  • Vehicles model year 1995 and older pay a flat $120 annual fee regardless of weight.
  • You can choose one-year or two-year registration at the time you register, with two-year registration costing more upfront but requiring fewer renewals.
  • First-time registrations in Connecticut also require a title process, which carries a separate fee you should confirm with the DMV.

Where to find your vehicle's weight class

Your vehicle's GVWR appears in your owner's manual, on a label inside the driver's door jamb, or on the vehicle's registration card if you've registered it before. You can also contact your vehicle's manufacturer or look it up using your vehicle identification number (VIN) through the Connecticut DMV website or a VIN decoder tool.

The Connecticut DMV publishes a fee schedule that groups vehicles by weight ranges. Once you know your GVWR, you can match it to the correct weight class and see the exact fee you'll owe. This prevents surprises when you arrive to register.

How to pay registration fees in Connecticut

You can register your vehicle in person at any Connecticut DMV branch office, by mail, or online through the Connecticut DMV portal if you're renewing an existing registration. In-person registration is fastest if you have all required documents. Mail registration takes longer but works if you cannot visit an office.

Payment methods vary by registration method. In-person registrations accept cash, check, or card. Online renewals accept credit or debit card. Mail registrations require a check or money order. The DMV does not accept payment over the phone.

Bring your current registration, proof of insurance, and a valid ID when you register in person. If registering a vehicle for the first time in Connecticut, you'll also need the title, bill of sale, and proof of residency. The DMV website lists the complete document checklist for your specific situation.

Registration renewal timing and costs

Your registration expires on a date printed on your registration card. Connecticut allows you to renew up to 30 days before expiration without penalty. Renewing early costs the same as renewing on time. If you renew after the expiration date, you may owe a late fee in addition to the registration fee.

Two-year registrations cost roughly double the one-year fee but spread the cost across two years if you think of it that way. The actual per-year cost is slightly lower with a two-year registration, so if you plan to keep the vehicle registered in Connecticut for two years, the two-year option saves money overall.

Additional fees you might owe at registration

If you're registering a vehicle in Connecticut for the first time, you'll pay a title process fee in addition to the registration fee. This fee varies depending on whether the vehicle is new to the state or transferring from another state. Vehicles with a lien (a loan against the car) may require additional documentation but do not cost more to register.

Vanity plates cost extra if you want a custom plate instead of a standard plate. Disabled person plates or veteran plates are available at no additional cost if you meet the requirements, but you must request them at registration. Specialty plates (environmental, military, college) may carry a small additional fee.

If your registration lapses and you drive with an expired registration, you risk a traffic ticket. The fine for driving with an expired registration in Connecticut is separate from the registration fee itself and can be substantial, so renewing on time is worth the effort.

Frequently Asked Questions

What if I don't know my vehicle's gross vehicle weight rating?

Check your owner's manual first—it's usually in the specifications section. If you don't have the manual, look for a label on the inside of the driver's door jamb or the door itself. You can also call your vehicle's dealership with your VIN and they'll tell you the GVWR. The Connecticut DMV website also has a VIN lookup tool.

Can I register my car online if it's a new registration, not a renewal?

No. Online registration through the Connecticut DMV portal is only for renewing an existing Connecticut registration. New registrations must be done in person at a DMV branch office or by mail. In-person registration is faster because you get your plates and registration card the same day.

Do I have to pay the full two-year fee if I only plan to keep the car registered for one year?

No. You choose one-year or two-year registration when you register. If you select one-year, you pay only the one-year fee. You can switch to two-year registration at your next renewal if you decide to keep the vehicle longer.

What happens if my registration expires while I'm out of state?

Your registration is still expired and driving with it is illegal, even if you're not in Connecticut. You must renew before you drive back into Connecticut or any other state. Renewing online or by mail before you return home prevents a traffic stop.

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 its own fee based on its weight class. You can register multiple vehicles at the same DMV visit if you have all required documents for each one.
