How to Transfer Car Registration in CT: Docs, Fees, and Taxes

To transfer a car registration in Connecticut, you’ll need the signed original title, a bill of sale, proof of Connecticut insurance, valid ID, and a completed Application for Registration and Certificate of Title (Form H-13B), submitted by appointment at a DMV hub or branch office. The base registration fee runs $120 for three years, and you’ll owe 6.35% Connecticut sales tax on the purchase price (7.75% above $50,000), plus a handful of smaller fees that bring a typical used-car transfer to around $199 before tax.¹

Documents You’ll Need

The seller’s signed original title is the anchor document. Connecticut doesn’t title vehicles more than 20 model years old, so for older cars the seller’s registration certificate plus a completed Supplemental Assignment of Ownership (Form Q-1) replaces the title.²

Bring these to your appointment:

Bill of sale with both parties’ names and addresses, a vehicle description, the sale price, and signatures.
Form H-13B, which handles both the title application and the new registration.
Proof of Connecticut insurance in your name, meeting the state minimums: $25,000 per person and $50,000 per accident for bodily injury, $25,000 for property damage, plus uninsured and underinsured motorist coverage.³
Valid ID: a Connecticut driver’s license, non-driver ID, or U.S. passport.
A passing emissions test result if the vehicle is older than four model years and not otherwise exempt.

The seller records the odometer reading on the title assignment (or on the Q-1 if the vehicle isn’t titled) at the time of sale.⁴ Federal law drops the odometer disclosure requirement for vehicles 20 model years old or more (for 2011 and newer model years) or 10 model years old (for 2010 and older).⁵

Before you leave the seller, check that the title’s assignment section is signed, the signature matches the printed name, and there are no crossed-out entries. Any of those issues can send you back for a duplicate title from the seller’s state.

What You’ll Pay

Connecticut breaks registration into several line items. For a standard passenger car, SUV, or van, expect:¹

Registration fee: $120 for three years⁶
Plate fee: $5 standard, $7 classic
Title fee: $25
Administrative fee: $10
Clean Air Act fee: $15
Passport to the Parks fee: $24, which funds free entry at state parks⁷
Emissions exemption fee: $40 for vehicles four model years old or newer
Lien fee: $10 if the vehicle has a lienholder
Greenhouse gas fee: $15 for vehicles with a certificate of origin (typically brand-new dealer purchases)

A used passenger vehicle with no lien runs about $199 in base fees before sales tax. A brand-new vehicle with a certificate of origin and the emissions exemption adds roughly $55 more.

If you already have Connecticut plates on another vehicle and want to move them to the new one instead of getting fresh plates, the transfer fee is $21 in place of the full registration and plate charges.⁶

Sales Tax and the NADA Rule

Sales tax is 6.35%, rising to 7.75% on any vehicle with a sales price above $50,000.⁸ A dealership collects it as part of your purchase; in a private sale, you pay it directly at the DMV.

Here is the catch for private sales. The DMV calculates tax on the bill of sale price or the NADA average trade-in value, whichever is higher.⁹ Paying $3,000 for a car NADA values at $8,000 means tax on $8,000. High mileage, body damage, or mechanical problems can justify a lower figure, but the higher number is the default.

Emissions Test or Exemption

Vehicles older than four model years usually need a passing emissions test before the DMV will finalize registration. Testing is done at designated stations statewide and produces a Vehicle Inspection Report.

These vehicles are exempt from testing:¹⁰

Vehicles four model years old or newer (they pay the $40 exemption fee instead)
Model year 2001 and older vehicles
Fully electric vehicles (hybrids are not exempt)
Motorcycles
Vehicles with a gross vehicle weight rating over 10,000 pounds
Farm vehicles

If testing is still pending when you need to drive, you can buy a 10-day temporary registration for $21, renewable in 10-day increments.¹¹

Where to File

Vehicle registration is by appointment only, at a DMV hub office, a DMV branch office, or a participating dealership.¹² Hub offices handle every transaction type; branch offices are more limited, so verify what your chosen location processes before booking. AAA “Express” locations in Connecticut don’t handle vehicle registration, only driver’s license renewals and ID cards.¹³

Private Seller vs. Dealership

With a private seller, the paperwork is yours. The seller hands you the signed title (or Form Q-1), a bill of sale, and the odometer disclosure. You line up your own insurance, complete the H-13B, and pay sales tax at the DMV.

A dealership handles most of it: collecting sales tax, filing your title application, submitting paperwork to the DMV. You usually drive off with temporary plates and receive the permanent registration and plates later. Dealers charge their own processing and documentation fees on top of the state’s fees, though the state fees themselves are identical either way.

Moving to Connecticut From Another State

New Connecticut residents have 90 days after establishing residency to transfer an out-of-state registration.¹⁴ Driving on out-of-state plates past that window carries a $250 fine, though first-time violators who then register can have it suspended.¹⁵

The process:

Get an emissions test if the vehicle is older than four model years. Vehicles otherwise exempt from emissions still need a VIN verification.
Gather your original out-of-state title, current out-of-state registration, proof of Connecticut insurance, valid ID, and the completed H-13B.
Schedule an in-person appointment at a hub or branch office.

There’s a useful tax break: if the vehicle was registered in your name in your prior state for at least 30 days before you established Connecticut residency, you owe no Connecticut sales tax on it.⁹

If a lienholder holds your title, ask them to send it before you register. If they can only provide a photocopy of the front and back while the original is in transit, you can get a courtesy registration valid for up to six months at 25% of the base registration fee plus other first-time fees. The lienholder mails the original to the DMV’s Title Section in Wethersfield, and the DMV then issues a Connecticut title to the lienholder of record. Courtesy registrations aren’t available for private ownership transfers, only for out-of-state transfers with an existing lien.

Family Transfers and Gifts

A transfer between immediate family members can qualify for a full sales tax exemption. Connecticut defines immediate family here as spouses, parents, children, siblings, grandparents, and grandchildren. Two conditions: the vehicle must have been registered in the family member’s name for at least 60 days before the transfer, and tax must have been paid on its last sale.¹⁶

For a gifted vehicle, use the Motor Vehicle or Vessel Gift Declaration (Form AU-463), signed by the person giving the vehicle.⁹ On the H-13B, list the recipient as the purchaser and enter the tax exemption code in section 5. All other fees and steps are the same.

Clear Property Taxes First

Connecticut municipalities levy an annual property tax on registered vehicles, assessed by your local town or city each October 1. The DMV runs a compliance check before processing most transactions, and unpaid vehicle property taxes will block your registration.¹⁷ Settle any outstanding balance with your town’s tax collector before your appointment. The DMV’s online self-service portal lets you check for compliance issues in advance.

Penalties for Driving Unregistered

Operating, parking, or letting someone else operate an unregistered vehicle on any Connecticut public road is an infraction.¹⁵ Within 30 days of expiration, you’ll face the lesser failure-to-renew fine and your license isn’t affected. Past that, the consequences escalate, and a Connecticut resident driving their own vehicle on another state’s plates faces the $250 fine noted above. The DMV can also void a registration obtained through a materially false application, with fees forfeited to the state. The 90-day new-resident window sounds generous until you factor in emissions testing, gathering documents, and waiting for a DMV appointment.
