Boats are taxable and are appraised annually at current market value as of January 1. Values are determined by reviewing purchase prices, sales of comparable boats and other market data. Information on their location and ownership is obtained from the Department of Motor Vehicles, the United States Coast Guard, marina listings and on-site inspections. San Joaquin County currently assesses approximately 10,000 boats.
Per the State Board of Equalization Letter to Assessor No 2022/003 - 2022 Vessel Valuation: "Current data indicates that the average retail sale prices for powerboats, sailboats, and personal watercraft (jet skis) have all experienced a large appreciation in value as compared to last year. This may be largely due to the COVID-19 pandemic, where the popularity of outdoor boating activities has increased substantially and a decrease in production has caused the demand for vessels to exceed the supply."
