Sell your car in Connecticut — and stop the property-tax clock while you're at it
Connecticut keeps the sale itself refreshingly simple: sign the back of the title, hand over a bill of sale, and no notary ever enters the room. The catch comes afterward — your car keeps accruing town property tax until you cancel the registration, which makes that seven-minute cancellation the most valuable paperwork in the state. Everything below is checked against the CT DMV's own pages.

The steps above apply in every Connecticut town; what differs is the car's property tax, which your town bills at its own mill rate until you cancel the registration. If you're selling in Hartford, its own page covers the local side.
How to sell a car in Connecticut
- 01Check AND or OR, and get any lender's letter. Look at the word between the owners' names: OR means one signature transfers the car, AND means every owner named must sign. If a lender is printed on it, get the lender's lien release letter first: Connecticut keeps no electronic lien record, and the buyer can't register the car without it. An instant cash offer here is the alternative to listing it.
- 02No title? You'll need a Q-1 either way. Connecticut doesn't require a title on a car more than 20 model years old. Without one, you sell it on the last registration certificate plus a Q-1 Supplemental Assignment of Ownership, which the DMV doesn't publish, so ask for one at a DMV office before sale day. The DMV's title exemption letter answers an out-of-state buyer who doubts it. Lost the title on a newer car? File the H-6B ticked as Ownership Transfer, with a Q-1 attached.
- 03Get paid, then sign the back of the title. Sign at handover, not before: the registration expires the moment the signed title changes hands, paid or not. Print the buyer's name and address in the assignment yourself. The title carries a warning in block letters against leaving it blank. Enter the mileage in whole miles on a 2011 or newer car; a 2010 or older is exempt. Use ink and no strikeovers, because a spoiled title means a $25 replacement. No notary is involved.
- 04Add a Connecticut bill of sale. It's required in every sale. The DMV's H-31 is optional, but whatever you use must list both names and addresses, the make, model, year, color and VIN, the price, the date and your signature. Write the real price: the buyer's tax is worked on the NADA average trade-in value or your price, whichever is higher. Giving the car away is a Form AU-463 gift declaration, not a $1 sale.
- 05Copy both, then take your plates. Photocopy the finished title and bill of sale before they leave the table. The plates stay with you. There's no Connecticut license plate return in an ordinary sale: you can discard them, move them to another car you own for $21, or hand them in at any DMV to be held.
- 06Terminate the registration the day you sell. Connecticut has no notice of sale or release of liability, so this is your cut-off. Until you do it, the car stays subject to property tax in your town. Online it's free and takes about seven minutes (have your license number, plate number and Social Security number ready); by mail it's the E-159. Print the plate receipt and use the same date as on the title and bill of sale. If a year or more is left on the registration, claim part of the fee back on the F-82 before the registration period would have ended.
- 07Drop the insurance only after the plate receipt. The CT DMV's seller page says not to cancel the insurance until the registration has been cancelled. Do it the other way round and your insurer reports the cancellation against a registration that's still live. That counts as a lapse and can bring a $200 civil penalty. If a lapse letter arrives anyway, answer it with the SR-101.
- 08Send the buyer to a DMV hub or branch office. The Connecticut title transfer is the buyer's job, in person and by appointment; there's no online route. They bring your signed title and bill of sale, a Connecticut insurance card in their own name and a completed H-13B, whose Section 3 repeats your name, sale date and price. They pay the $25 title fee, the registration and 6.35% sales tax (7.75% on a vehicle over $50,000), and they must register before driving the car. Most cars from model years 2002 to 2022 also need a Connecticut emissions test within 30 days of registering, and the DMV sends no reminder.

What Connecticut requires when you sell
| Notary | Not part of a Connecticut sale. The DMV's seller checklist asks for exactly two documents — the signed title and a bill of sale — and neither one needs a stamp. |
|---|---|
| The title form | There isn't a separate one. You complete and sign the reverse side of the certificate of title and hand it to the buyer, along with a bill of sale. The DMV supplies Form H-31 but says no special form is required, as long as yours lists both parties' names and addresses, the vehicle description with VIN, the price, the sale date, and your signature. |
| Bill of sale | A CT bill of sale is required in every sale: it goes to the buyer with the signed title. The form is up to you. The DMV's Form H-31 is optional, and a sheet you write yourself works if it has both parties' names and addresses, the make, model, year, color and VIN, the price, the date and your signature. The H-31 prints two copies on one sheet so you keep one. The DMV's current guidance also asks for the buyer's signature, which the 2017 H-31 has no line for, so have the buyer sign beneath the certification. Source: CT DMV, Sell your vehicle. |
| Selling a car over 20 years old | Vehicles more than 20 model years old are exempt from Connecticut's title requirement. You complete the Supplemental Assignment of Ownership (Form Q-1) and hand over the most recent registration certificate instead — and the DMV warns the transfer isn't valid unless the Q-1 is completed. |
| Lost your title? | File Form H-6B with a $25 fee. Online is the fast lane — about 7 minutes to file, replacement within 20 business days — while a mailed application can take up to 90 days. Selling to another Connecticut resident before it arrives? The DMV says to pair the H-6B with a completed Q-1. |
| Protect yourself after the sale | Connecticut has no notice of sale and no release-of-liability form — terminating your registration is your cut-off. It's free and takes about 7 minutes online, or use Form E-159 by mail. It matters because the vehicle stays subject to property tax in your town of record until you cancel. Keep the plate receipt. Money left on the registration doesn't come back on its own: with a year or more remaining, claim a one-third or two-thirds refund on Form F-82 before the registration period would have expired. |
| License plates | They stay with you, not the car. Remove them before the buyer drives off, cancel the registration, and keep your liability insurance active until the DMV confirms the cancellation went through. |
| Sales tax | The buyer's bill, due at registration: 6.35%, or 7.75% on vehicles over $50,000. On a private sale the DMV computes it on the NADA average trade-in value or the bill-of-sale price, whichever is higher — a lowballed bill of sale saves nobody a dime. Immediate-family sales are exempt (Section 5 of Form H-13B) when the vehicle was registered to the previous owner for at least 60 days. |
| Inspections | No periodic safety inspection for standard passenger cars. The recurring item is the emissions test: $20.00, due every two years, with a $20 late fee per missed test. Exempt: vehicles younger than four model years, model year 2001 and older, over 10,000 lbs GVWR, full EVs, and motorcycles. When a car is sold, the test is the buyer's: within 30 days of registering, and the DMV sends no reminder. |

Asked by Connecticut sellers
Do I need a notary to sell my car in Connecticut?
No. The CT DMV's checklist for sellers is two documents — the certificate of title, signed on the reverse, and a bill of sale — and neither requires notarization. Form H-31 is the DMV's own bill-of-sale template, but any version listing both parties' names and addresses, the make, model, year, color and VIN, the price, the sale date, and your signature is acceptable.
How do I protect myself after selling a car in Connecticut?
Cancel the registration. Connecticut has no notice-of-transfer or release-of-liability form, so the cancellation is your official break from the vehicle — until it happens, the car remains subject to property tax assessment in your town of record. Cancellation is free, takes about seven minutes online, and the DMV says to keep the receipt. Hold your insurance until the DMV confirms it.
Who pays sales tax on a private car sale in Connecticut?
The buyer, when they register the vehicle — 6.35%, or 7.75% if it sold for more than $50,000. The DMV calculates the tax on the NADA average trade-in value or the bill-of-sale price, whichever is higher, so writing a friendlier number on the bill of sale doesn't shrink anyone's bill.
Can I sell a Connecticut car that's more than 20 years old without a title?
Yes — vehicles over 20 model years old are exempt from the state's title requirement. You complete the Supplemental Assignment of Ownership, Form Q-1, and hand over the latest registration certificate instead. The DMV is blunt that the transfer isn't valid unless the Q-1 is filled out, so don't skip it.
