How to Fill Out a Bill of Sale in Connecticut

A step-by-step guide to every field on a Connecticut vehicle bill of sale — with a free filled-in example you can download instantly.

Connecticut publishes its own bill of sale, Form H-31, and applies a two-tier tax the buyer should see coming when you write the price: 6.35% on most vehicles, jumping to 7.75% on any vehicle over $50,000. Fill out the H-31 completely: parties, vehicle, VIN, odometer, the true price, date, signatures (no notary on the H-31 or the title assignment). Two CT-specific handover details: the plates come OFF and stay with the seller (return them to the DMV or transfer them — an active registration on a sold car is a Connecticut insurance-lapse trap), and buyers of vehicles from certain out-of-state or older categories should budget for the VIN verification step before registration.

Step-by-Step: Every Field Explained

Seller Information

Full legal name
Current mailing address
City, state, ZIP code
Phone number (optional but recommended)

Tip: Before writing anything, open the ownership document and transcribe the seller's name from it — the Connecticut DMV treats it as the reference copy.

Buyer Information

Full legal name
Current mailing address
City, state, ZIP code
Phone number (optional)

Tip: Write the buyer's name for the record it becomes — future registration, insurance, and resale all inherit this line.

Vehicle Description

Vehicle year (4-digit)
Make (manufacturer — e.g., Ford, Toyota)
Model (e.g., F-150, Camry)
Body style (e.g., sedan, pickup, SUV)
Color
VIN (Vehicle Identification Number) — 17 characters, found on the dashboard or door jamb
Odometer reading at time of sale

Tip: Take the VIN from the car, compare it to the title, and only then write it down — VIN typos are the most common reason transfers fail.

Sale Details

Sale price in US dollars (write out both numerals and words — e.g., "$8,500 — Eight thousand five hundred dollars")
Payment method (cash, check, electronic transfer)
Date of sale (month / day / year)
Note: the buyer pays Connecticut tax at registration (6.35% — 6.35% (7.75% over $50,000))

Tip: Record the true price, not a rounded-down one; for the 6.35% vehicle tax in Connecticut, the paperwork should match the payment.

Seller Signature

Seller's signature (must match title)
Printed name
Date signed

Tip: There's no notary step in Connecticut — once both parties sign, the document is done. Store your copy somewhere you'll still find it in five years.

Buyer Signature

Buyer's signature
Printed name
Date signed

Tip: Sign in duplicate: one complete original per party. Photos and scans are backups, not substitutes.

Form H-13B (Registration and Title Application)

Frequently Asked Questions

Is Form H-31 required at the Connecticut DMV?

It's the DMV's own bill of sale and the expected document at title transfer — a private bill of sale with identical fields also works, but a bill of sale of some kind is always required to register. Bring it with the signed-over title; the DMV taxes the higher of the recorded price or the NADA average trade-in value.

When does the 7.75% luxury rate apply?

When the vehicle's sale price exceeds $50,000 — the whole price is then taxed at 7.75% instead of 6.35%. Relevant for late-model trucks and premium EVs more often than people expect.

What do I do with Connecticut plates after selling?

They're yours, not the car's: remove them at handover, then transfer them to your next vehicle or return them to the DMV for a cancellation receipt. Insurance can't be safely cancelled until the plates are surrendered or transferred.

Does Connecticut require notarization?

No — neither the H-31 nor the title assignment requires a notary for a private-party sale.
