Many types of equipment used in business as well as personal property such as boats and aircraft are subject to property tax in California. The Business and Personal Property Appraisal Division values all types of business property from that owned by small family businesses to that owned by large firms and agricultural operations. All privately owned boats and airplanes in Sonoma County are also valued. The valuation of a business is based upon the filing by the taxpayer of a Business or Agricultural Property Statement annually. This division also audits the accounting records of selected businesses to verify the accuracy of the data reported on the property statements.
We value and maintain assessment information for approximately 20,000 businesses, 15,000 pleasure and commercial boats, and 900 private aircraft.
