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 Form H-31 — one of the few DMVs whose bill of sale carries its own form number and is expected at the counter — 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 anywhere in Connecticut's chain). 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

1

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.
2

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.
3

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.
4

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: buyer owes 6.35% Connecticut sales tax on the sale price at registration
Tip: the 6.35% sales tax in Connecticut is calculated from this line (cross-checked against market value), so the honest price is the only one that works.
5

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.
6

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.

Other Forms Required in Connecticut

Along with the bill of sale, you may need these additional documents for a Connecticut vehicle transfer:

  • Form H-31 (Bill of Sale)
  • 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. Bring it with the signed-over title; the DMV uses the recorded price for the sales tax assessment.
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.
