Washington Bill of Sale
Washington gives the seller five days, the buyer fifteen, and taxes what the car is worth rather than what you paid. The official TD-420-065 and both deadlines, explained from each side of the deal.
Two clocks start when the keys change hands.
Washington specifics, answered.
Is a bill of sale required in Washington?
Effectively yes — the buyer can't title the vehicle without one unless the sale price and date are written on the title itself. Form TD-420-065 is the official version, covering vehicles and vessels, and it's what the licensing office expects alongside the title within 15 days.
What is the seller's 5-day Report of Sale?
Washington's statutory liability cutoff (RCW 46.12.650): the seller files a Vehicle Report of Sale within 5 days — online without even needing an account, in person, or by mail — and from that moment the buyer's parking tickets, tolls, and worse belong to the buyer. It's separate from, and just as important as, the bill of sale.
What does the buyer pay if the title transfer runs late?
An automatic, escalating penalty: $50 on day 16, then $2 for every additional day, capped at $125. Combined with tax and fees due at the county licensing office or a private subagent (who add service fees), procrastination in Washington has a posted price.
Why did the tax come out higher than my purchase price math?
Because Washington's use tax is assessed on the vehicle's average fair market value, not the stated price. A below-market deal means the buyer submits proof of the vehicle's condition and value — and the Department of Licensing can still assess on the higher number. Photos and a detailed bill of sale are the buyer's evidence kit here.
