Washington Vehicle Sales Tax Calculator
See regular sales tax, the additional motor-vehicle tax and luxury tax as separate amounts rather than one combined dealer figure.
Start with the deal price.
Use the negotiated selling price, not the monthly payment.
Regular sales-tax rate
Washington's regular rate varies by location. Enter the current combined location rate shown by the official lookup or dealer documentation.
Additional motor-vehicle tax
For a 2026 purchase, the engine separately applies the 0.5% additional motor-vehicle sales/use tax.
Luxury motor-vehicle tax
The calculator applies 8% only to the portion of the adjusted selling price above the $100,000 threshold for a 2026 purchase. Thresholds are date-sensitive and must be reviewed for later years.
The calculator distinguishes official fixed rules from local or user-entered estimates. Dealer worksheets and licensing-office totals remain the final transaction records.
