In 2016 voters in the Sound Transit district approved an increase in the Regional Transit Authority (RTA) Motor Vehicle Excise Tax (MVET) to fund the mass transit expansion described in Sound Transit 3. This vote increased the MVET rate from .3 percent to 1.1 percent annually, or $110 for each $10,000 of depreciated vehicle value.
The RTA tax is calculated from the depreciated value of your vehicle. It is determined by using a formula based on the vehicle manufacturer’s suggested retail price (MSRP), or purchase price for commercial trucks and commercial trailers, and a depreciation schedule set by state law based on the age of the vehicle.
