In Connecticut, a passenger car registration lasts up to three years from the date it’s issued, with a $120 base fee covering that full period. State law lets the DMV commissioner set the exact term at either two or three years, and three is what most passenger vehicle owners get. Drivers who are 65 or older can opt into a one-year cycle instead, renewed each year at their choice.1Connecticut General Assembly. Connecticut General Statutes Chapter 246 – Motor Vehicles
The Three-Year Standard and the Senior Option
Connecticut General Statutes Section 14-22 sets the registration term at two or three years from issuance, and the passenger vehicle fee schedule prices the standard cycle at $120 every three years. That three-year term is what a typical car, SUV, or van owner will see on the sticker.1Connecticut General Assembly. Connecticut General Statutes Chapter 246 – Motor Vehicles
If you’re 65 or older, the shorter one-year cycle is available on request. The per-year rate works out the same either way; the appeal is a smaller bill at each renewal. The choice is yours at every renewal, not a one-time election.1Connecticut General Assembly. Connecticut General Statutes Chapter 246 – Motor Vehicles
Commercial and seasonal vehicles run on different terms. A commercial vehicle used in seasonal operations can register for a consecutive six-month period at half the annual fee.2Connecticut eRegulations. Connecticut Regulations Section 14-48c-2 – Registration, Expiration Date, Fee
What the Registration Period Costs
The $120 base fee covers the registration itself for the full term, but Connecticut adds several charges on top when you register a passenger vehicle:3DEPARTMENT OF MOTOR VEHICLES. DMV Fees
- Registration fee: $120
- Plate fee: $5
- Title fee: $25
- Administrative fee: $10
- Clean Air Act fee: $15
- Passport to the Parks fee: $24 (effective July 1, 2025)
- Lien fee: $10 per lienholder, if the vehicle is financed
- Emissions exemption fee: $40 if the vehicle is four model years old or newer
- Greenhouse gas fee: $15 if the vehicle has a certificate of origin
A new passenger registration with a lien can run past $250 before any sales or property tax is added.
Renewing Before the Term Ends
The DMV sends a renewal invitation by mail or email roughly 45 days before your registration expires. The notice lists your fee, any emissions requirement, and any compliance issues you’ll need to clear first, such as unpaid property taxes, parking tickets, or an insurance lapse. Not receiving the notice doesn’t excuse a late renewal.4DEPARTMENT OF MOTOR VEHICLES. Renew Your Vehicle Registration
You can renew three ways:
- Online, using your name as it appears on your license, license number, date of birth, address, plate number, Social Security number, and a credit or debit card. Print the confirmation and keep it in the vehicle.4DEPARTMENT OF MOTOR VEHICLES. Renew Your Vehicle Registration
- By mail, returning the bottom portion of your renewal notice with payment to the DMV at P.O. Box 150456, Hartford, CT 06115-0456.
- In person at any DMV office, with your renewal invitation or, failing that, your driver’s license or state ID.
Two things routinely block renewal even when the fee is ready. Emissions testing is required for most vehicles, and a missed test will hold up the renewal until you pass. And any unpaid municipal motor vehicle property tax stops the process cold; the DMV won’t process the renewal until your town clears you. If you’ve moved between Connecticut towns, check that both the old and new municipality show you as current.5DEPARTMENT OF MOTOR VEHICLES. Register a New Vehicle or Boat in CT
What Happens if You Let It Lapse
A $10 late fee applies if you renew more than five days after the expiration date. It hits on day six. That’s a narrow window, and it isn’t a legal grace period for driving; your registration is expired the moment the date passes.4DEPARTMENT OF MOTOR VEHICLES. Renew Your Vehicle Registration
Operating or even parking an unregistered vehicle on a Connecticut public road is an infraction under General Statutes Section 14-12. The same statute imposes a fine of $150 to $300 on a Connecticut resident caught driving a vehicle they own on plates from another state.6Justia.

An unregistered vehicle found on the road can also be impounded, and a vehicle that goes unclaimed for 45 days after impoundment may be subject to forfeiture. A $10 late fee is a much cheaper problem than a traffic stop, a tow, and storage charges.
