Sales tax and the 0.3% add-on
RCW 82.08.020 adds 0.3% to the sale of every motor vehicle, on top of the retail sales tax, and the money funds the multimodal transportation account. Local rates follow where you live. A like-kind trade-in is excluded from the selling price, capped at the price of the car you're buying.
A separate tax applies to vehicles whose price plus trade-in is over $100,000: 8% of the amount above the threshold, which is $100,000 for fiscal 2026 and adjusts each July 1.
