A cash receipt for the sale of a car — commonly called a bill of sale — is the written record of a private vehicle transaction. It should name the buyer and seller, describe the vehicle, state the exact price and date, carry both signatures, include an odometer reading, and say the car is sold as-is. Done properly, it protects the seller from later liability and gives the buyer the paperwork they need to register the car.
Under the Uniform Commercial Code, a contract for the sale of goods priced at $500 or more generally must be in writing to be enforceable.1Legal Information Institute. Uniform Commercial Code 2-201 – Formal Requirements; Statute of Frauds Almost every car sale clears that threshold, so a written receipt isn’t optional if either side ever needs to enforce the deal.
What to Put on the Receipt
A good bill of sale leaves nothing for either party to dispute later. Include:
- Full legal names and addresses of buyer and seller, matching their government-issued IDs.
- Vehicle year, make, model, body style, color, and the 17-character Vehicle Identification Number.
- The odometer reading at the time of sale.
- The sale price, written in both numerals and words so it can’t be altered.
- The calendar date of the transaction.
- Signatures of both parties, dated.
Write the price that was actually paid. A lower figure to shave the buyer’s tax bill is fraud, and a higher figure creates its own problems if the sale is ever audited. The sales tax the buyer owes at registration will be assessed against the number on this receipt, and an underreported price can trigger an audit or a tax bill based on the vehicle’s fair market value instead.
The As-Is Clause
Private sellers almost never want to carry warranty obligations after the keys change hands, but that protection isn’t automatic. If the receipt is silent on condition, a buyer can argue that implied warranties applied. The UCC allows a seller to exclude all implied warranties with language like “as is” or “with all faults,” provided the wording makes plain to the buyer that no guarantees are being made.2Legal Information Institute. Uniform Commercial Code 2-316 – Exclusion or Modification of Warranties
One sentence does the job: “The vehicle is sold as-is, with no warranties expressed or implied regarding its condition, fitness, or merchantability.” That line can be the difference between a tough phone call and a lawsuit when the transmission goes out next week.
Odometer Disclosure
Federal law requires anyone transferring ownership of a motor vehicle to provide a written disclosure of the cumulative mileage.3Office of the Law Revision Counsel. 49 USC 32705 – Disclosure Requirements on Transfer of Motor Vehicles The disclosure must state whether the reading is accurate, whether the odometer has rolled past its mechanical limits, or whether the actual mileage is unknown. Lying on it is a federal violation.
Not every vehicle needs one. Model year 2010 and earlier vehicles are exempt. For model year 2011 and newer, the disclosure requirement runs 20 years from the model year, so a 2011 model is covered through 2031.4National Highway Traffic Safety Administration. Consumer Alert: Changes to Odometer Disclosure Requirements Many states print a compliant odometer section on the title itself. If yours doesn’t, complete a separate disclosure form and have both parties sign it in ink.
Handling the Cash Safely
Carrying several thousand dollars in cash to meet a stranger has obvious risks, and a couple of simple choices reduce most of them.
Meet at a bank. A teller can verify the bills on commercial-grade counterfeit-detection equipment, which beats holding bills up to the light or using a detection pen. Those pens only check whether the paper reacts to starch and will miss a well-made fake printed on washed genuine currency. If a bank won’t work, many police departments offer “safe exchange zones” in their parking lots with 24-hour surveillance.
Count the money before anything gets signed. Once the receipt is signed and the title endorsed, undoing the deal is a legal headache. If the count comes up short or anything feels off, stop the transaction.
Signing and Distributing Copies
Both parties should sign at the same time, with both people present. Prepare two identical copies in advance so each person signs both. The buyer takes one signed original for their registration paperwork; the seller keeps the other as proof of the date and terms. The seller’s copy is the primary evidence that they no longer have the car, which matters if parking tickets, toll violations, or accident claims surface later.
Check ID. Ask to see a driver’s license and confirm the name matches what’s on the receipt and the title. The buyer’s name on the receipt should match the name that will go on the new title application.
The Title Is What Actually Transfers Ownership
The receipt proves the deal happened. The certificate of title is what makes the buyer the legal owner. Without a properly signed title, the buyer can’t register the car, and in the state’s records the seller still owns it.
Procedures vary by state, but the seller generally signs the back of the title in the assignment area and fills in the buyer’s name, the price, the date, and the odometer reading. Some states require the seller’s signature to be notarized.
Check for Liens First
Before cash changes hands, a buyer should confirm the title is clean. A lien means a lender has a legal claim to the vehicle, and that claim survives the sale. If a loan is still open, the lender’s name will appear on the title. The Department of Justice runs the National Motor Vehicle Title Information System (NMVTIS), which pulls title, lien, and salvage data from states and insurers. Buyers can run a NMVTIS check through an approved provider before committing.
Don’t Sign a Title “In Blank”
A title signed by the seller with the buyer’s name left empty — an “open title” — is illegal in many states and will create registration problems down the line. Fill in the buyer’s name, address, and the sale details at the time of signing.
Report the Sale to Your State Motor Vehicle Agency
After the sale, the seller should file a notice of transfer with their state’s motor vehicle agency. The name varies, but the purpose is identical everywhere: it severs the seller’s legal connection to the vehicle so that later parking tickets, toll violations, red-light fines, and accident claims don’t come back to them.
Deadlines run from as few as five calendar days in some states to 30 days in others. Most states take the filing online or by mail. This is one of the most commonly skipped steps in a private sale and the one that causes the most trouble months later.
Keep Insurance Active Until the Transfer Is Done
Don’t cancel coverage the moment the buyer drives off. Until the title is fully transferred and the sale is reported, the car may still be registered in the seller’s name, and an accident during that gap can create financial exposure for the former owner. Keep the policy in force until the title is signed over, the receipt is complete, and the notice of transfer is filed. Then cancel.
Sales Tax, Form 8300, and Keeping Records
Private sales don’t skip sales tax. In most states, the buyer pays sales or use tax on the purchase price when they apply for title and registration. The motor vehicle agency collects it then, so the buyer should budget for it on top of the cash paid to the seller.
Federal law requires anyone who receives more than $10,000 in cash in the course of a trade or business to file IRS Form 8300 within 15 days.5Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 A private individual selling a personal car in a one-time transaction is generally not acting in a trade or business and does not need to file Form 8300.6Office of the Law Revision Counsel. 26 USC 6050I – Returns Relating to Cash Received in Trade or Business If you regularly buy and sell vehicles for profit, the rule does apply, and “cash” for this purpose includes cashier’s checks, money orders, and bank drafts with face amounts of $10,000 or less used in a qualifying transaction.7Internal Revenue Service. 8Internal Revenue Service. Topic No. 409 – Capital Gains and Losses If a vehicle actually appreciates and sells for more than you paid, the profit is a taxable capital gain.
Either way, keep your copy of the receipt for at least three years, the standard IRS limitations period. Seven years is safer if you think a longer audit window could apply.9Internal Revenue Service. How Long Should I Keep Records A fireproof box or a scanned backup works.
