Washington Bill of Sale Laws and Requirements

A bill of sale in Washington is a legal document that records the transfer of personal property — most commonly a vehicle, boat, or other titled asset — from a seller to a buyer. The document establishes the purchase price, condition, and transfer date, serving as critical evidence for DMV title transfer, sales tax calculation, and liability protection. Washington imposes specific requirements for vehicle title transfers and private-party sales, including rules on notarization, DMV documentation, sales tax calculation, and odometer disclosure. A properly executed bill of sale protects both the seller and buyer in Washington by documenting the transaction terms.

Without a bill of sale, both parties face significant risks. The seller remains liable for parking tickets, tolls, and accidents involving the vehicle until title transfer is complete. The buyer lacks proof of the agreed purchase price and may be assessed sales tax on the vehicle's full fair market value instead. For vehicles, a bill of sale should always accompany the signed title certificate. For items without titles (furniture, electronics, equipment), the bill of sale is the only legal proof of the transaction. Use our bill of sale generator to create a Washington-compliant document that protects both parties. If the buyer is financing the purchase, pair it with a promissory note documenting the payment terms.

Washington Bill of Sale Requirements

DMV requirement: Check whether Washington requires a bill of sale for vehicle title transfers — even when not required, a bill of sale documents the purchase price for sales tax purposes.

Notarization: Some states require the seller's signature on the title to be notarized — verify Washington's current requirements.

State form: Washington may provide an official bill of sale form through the DMV — using the official form may expedite processing.

Sales tax: The purchase price on the bill of sale determines Washington sales tax or use tax owed by the buyer.

Title transfer: Washington typically requires the buyer to complete the title transfer within a specific deadline after purchase.

Odometer disclosure: Federal law and Washington law require accurate odometer disclosure for motor vehicle sales involving vehicles under 10 years old.

As-is disclaimer: Include an explicit as-is disclaimer in private-party sales to limit seller liability under Washington law.

Washington Bill of Sale FAQ

Do I need a bill of sale to sell a car in Washington?

Our bill of sale generator creates a Washington-compliant document in minutes.
Does a bill of sale need to be notarized in Washington?
Notarization requirements vary by state and transaction type. Even when the bill of sale itself does not require notarization, Washington may require the seller's signature on the title certificate to be notarized for the DMV to process the transfer. Notarization also adds authentication that prevents disputes about signature validity.
How much sales tax do I pay on a vehicle in Washington?
Sales tax rates vary by state and often by county. The purchase price stated on your bill of sale determines the tax owed. The purchase price stated on the bill of sale is the basis for tax calculation — some states compare this to the vehicle's fair market value and tax the higher amount to prevent underreporting. Accurate documentation in the bill of sale is essential.
What should a bill of sale include in Washington?
A Washington bill of sale should include: full legal names and addresses of buyer and seller, detailed vehicle description (year, make, model, VIN, color), odometer reading, purchase price, payment method, date of sale, as-is disclaimer or warranty terms, lien disclosure, and both parties' signatures.
