Registering a Vehicle in Connecticut

Connecticut requires every motor vehicle operated on public roads to be registered with the Connecticut Department of Motor Vehicles. New residents have 60 days from establishing residency to register, and existing residents have to register at the time of purchase. The state's town-level vehicle property tax adds a recurring obligation that doesn't exist in most other states.

The 60-day rule for new residents

Anyone moving to Connecticut must register their vehicle within 60 days of becoming a resident. "Resident" generally means establishing a primary domicile — renting or buying a home, registering to vote, accepting employment, or enrolling children in a Connecticut school. The CT DMV checks against the address on a Connecticut driver's license; if the license shows a CT address, the vehicle must be registered in Connecticut.

Documents required for first registration

• Out-of-state title (if titled elsewhere) or Manufacturer's Certificate of Origin (for new vehicles).
• Bill of sale showing the purchase price and date.
• Connecticut insurance policy declaration page meeting the 25/50/25 minimum plus uninsured-motorist coverage.
• Connecticut driver's license or other state-issued ID.
• Form B-345 Application for Registration and Certificate of Title.
• VIN verification by a Connecticut DMV inspector or licensed dealer (for vehicles brought from out of state).
• Federal odometer disclosure on form Q-1 if the vehicle is less than 20 model years old.

Sales tax

Connecticut charges 6.35% state sales tax on most vehicle purchases at the time of registration, calculated on the purchase price or the NADA clean retail value (the higher of the two for transactions between private parties). Vehicles with a purchase price over $50,000 pay the higher 7.75% luxury rate on the full purchase amount. Trade-in credit applies — only the net price after trade-in is taxed when buying through a dealer.

Title and registration fees

• Title fee: $25.
• Standard passenger registration: $80 for 2 years (passenger plates).
• Vanity plate: add $50 to the registration fee.
• VIN verification: $10 if performed at a DMV branch.
• CTVIP emissions test: $20 every 2 years (most vehicles 4-25 model years old). See CT registration renewal.
• Lien recording fee: $10 if a lender holds title.

Town vehicle property tax

The single most distinctive feature of Connecticut vehicle registration is the annual town property tax. Each of Connecticut's 169 towns assesses a personal property tax on every motor vehicle registered to a town address as of October 1 each year. The bill arrives in July from the town tax collector. Mill rates vary widely — Hartford runs near 32 mills (the post-2022 reform cap), while wealthier towns like Greenwich are around 12. New residents pay a prorated assessment for the partial first year.

Connecticut emissions inspection (CTVIP)

Most gasoline vehicles model year 4 through 25 must pass an emissions test through the Connecticut Vehicle Inspection Program (CTVIP) before registration or registration renewal. The test is performed at a CTVIP licensed station and reads the on-board diagnostics computer for newer vehicles, with a tailpipe test for vehicles too old for OBD-II. New vehicles purchased from a Connecticut dealer get an automatic 4-year exemption; vehicles 26+ model years old are also exempt. A failing vehicle has 60 days for repairs and a free retest.

Out-of-state titles and "Verified by Lender" cases

If the vehicle is brought from out of state with a lien still active, the lender holds the original title. Connecticut accepts a "Verified by Lender" filing where the DMV registers the vehicle while the title remains with the out-of-state lender. The owner provides the lender contact information, the lien-payoff statement, and the registration application. The Connecticut title is then created when the lien is released.

Where to register

Most first-time vehicle registrations in Connecticut are completed at one of the eight full DMV branches. Some transactions can be initiated online but cannot be finalized without an in-person VIN inspection. After the initial registration, all renewals can be processed online or by mail, assuming property tax compliance and emissions are current. See CT title transfer for buyer-seller specifics.
