Non-Commercial (Private) Aircraft - Frequently Asked Questions
- Q: How did you arrive at that value?
- A: Values are based on aircraft market value guides and the filed Aircraft Property Statement.
- Q: What if I sold the airplane?
- A: Notify us in writing, and attach a copy of the bill of sale.
- Q: What if I don't file the Aircraft Property Statement?
- A: Failure to file an Aircraft Property Statement will require the Assessor to estimate the market value of the aircraft and apply a penalty assessment (Revenue and Taxation Code Sections 501 and 5367).
- Q: When and where is an aircraft assessed for property taxes?
- A: State law requires that aircraft be assessed on January 1 of every year, at the site where they are regularly or routinely located. Aircraft regularly located in Alameda County are assessed here, regardless of where they are registered.
