Regional Transit Authority (RTA) Motor Vehicle Excise Tax (MVET) depreciation schedule

Sound Transit uses these depreciation tables for RTA tax.

Depreciation Curve

Taxable value is based on vehicles age (year of service) and a base value established by the vehicle Manufacturer’s Suggested Retail Price (MSRP) for passenger vehicles, motorcycles, light-duty trucks (scale weight of 6,000 pounds or less) and small trailers.

For passenger vehicles, motorcycles, light-duty trucks, and small trailers: Take the vehicle’s MSRP, find the Year of Service (current calendar year - model year + 1 year = year of service), and apply the corresponding percentage.
