What Is License Plate Renewal in Connecticut?
License plate renewal in Connecticut extends the registration of a vehicle without changing the plate number. The Connecticut Department of Motor Vehicles issues a new registration certificate; Connecticut does not use a sticker or tab for confirmation.
- Three-year cycle. Standard registrations for passenger cars, SUVs, vans, trucks, and motorcycles last three years. One-year and two-year terms are available in certain cases, including for owners aged 65 and older, according to Conn. Gen. Stat. § 14-49.
- Renewal is separate from titling. Selling or transferring a vehicle requires a separate title transaction at the DMV office; renewal only extends the existing registration.
- Passenger cars, motorcycles, trailers, RVs, and commercial vehicles follow the same three-year default, though commercial and seasonal registrations may use annual terms. Electric vehicles renew on the same cycle as gasoline cars.
When Do You Need To Renew Your Connecticut License Plate?
The DMV sends a renewal invitation by mail or email 45 days before the expiration date. This notice signals the start, and online renewal opens immediately upon its creation.
- Owners can renew up to 45 days before expiration through any channel: online, by mail, by phone, or in person at a DMV office.
- Five-day grace period. The DMV allows five days after the expiration date before applying a late fee.https://portal.ct.gov/dmv/resources/make-change-appointment
- On the sixth day, a fixed late fee of $10 is added to the renewal. Fees in the next section are added to this penalty window.
- Vehicles in the Connecticut Emissions Program must have a current biennial OBD test before the DMV processes the renewal. The program covers gasoline vehicles of model years 2002 and newer that are older than four model years. Motorcycles, fully electric vehicles, and vehicles with a GVWR over 10,000 pounds are exempt.
How To Renew Your License Plate in Connecticut
Before choosing a channel, ensure there are no compliance blocks. The DMV checks for current liability insurance, passing emissions test (if required), paid municipal property taxes, and any unresolved parking tickets. The online compliance check tool allows owners to verify their status before starting.
- Online: start the renewal at the Connecticut DMV online renewal portal. Enter your license and plate information, confirm the vehicle, and pay. Print the updated registration certificate immediately; the DMV keeps it available online for 30 days.
- For in-person renewal, schedule an appointment through the DMV appointment system. Offices in Wethersfield, Bridgeport, Danbury, Hamden, Norwalk, Waterbury, and other locations handle registrations. Bring the renewal notice or valid ID.
- By mail, return the bottom portion of the renewal notice with payment to: Department of Motor Vehicles, P.O. Box 150456, Hartford, CT 06115-0456.
- The online channel handles most types of registrations. Ambulance, construction, factory, hearse, and several other special classes must renew in person.
How Much Is License Plate Renewal in Connecticut?
The registration fee itself is only one component of the bill; mandatory clean air, greenhouse gas reduction, and state park access surcharges quickly add to the base.
- Passenger cars, SUVs, and vans pay $120 for a three-year registration (about $40 per year). Motorcycles pay $63 for three years. Regular trailers renew for $28.50. Conn. Gen. Stat. § 14-49 regulates these base levels.
- Mandatory surcharges on each passenger renewal (three-year amounts): $15 Clean Air Act fee, $15 greenhouse gas reduction fee, and $24 Passport to the Parks fee (effective July 1, 2025). A $10 administrative fee also applies.
- Connecticut does not add county fees to registration. Municipal vehicle taxes are billed separately by your city.
- Emissions testing, where required, costs $20, paid directly to the testing center. A separate $20 penalty from the DMV applies if the test is completed more than 30 days past due.
- The $10 late registration penalty mentioned in the timing section above is a fixed fee, not a monthly surcharge.
- Vanity plates add $15 per renewal to standard fees. Some special organizational plates have a $55 renewal surcharge instead.
Can I Renew My License Plate Online in Connecticut?
The Connecticut DMV online renewal service covers nearly all non-commercial registration types, limited to renewal transactions only (not first registrations or title transfers). The portal accepts Visa, American Express, Mastercard, and Discover credit and debit cards. Upon payment, the updated registration certificate is available for immediate printing; no physical sticker or tab is mailed.
Registrations expired longer than the renewal period cannot be renewed online. These owners must schedule a DMV appointment at one of the state’s nine branches.
The mail alternative requires:
- The bottom portion of the renewal notice, completed with payment information.
- A check or money order made out to “DMV,” sent to P.O. Box 150456, Hartford, CT 06115-0456.
If the DMV can process your plate online, it’s the fastest path without additional processing fees; the office handles what the portal won’t accept.
