Attention!A Message to Boat Owners

Dear Alameda County Residents:

Many vessel owners will see an increase in their 2022 property tax valuations!
 
The valuation factors calculated by the State Board of Equalization and provided to California County Assessors through LTA 2022/003 indicate an increase in 2022 values between 20-24% depending on the type of vessel. The State Board of Equalization reviews average retail sale prices for new and used powerboats, sailboats, and personal watercraft annually to develop the valuation factors. Per their research, these vessels have experienced large appreciation in value compared to 2021.

Sincerely,

The Alameda County Assessor’s Office
