Aircraft registered outside of the Golden State may become subject to additional Los Angeles County taxes if they spend extended periods in the state. Under California law, an aircraft is subject to property tax after logging 19 overnight stays a year, or roughly 5% of the year.

Technology Meets Tax Compliance
In a statement released by Los Angeles County officials noted that it has become increasingly challenging to identify taxable aircraft due to some aircraft owners exploiting complex registration practices and data gaps to avoid detection.
To meet this challenge, the L.A. County Assessor’s office has invested in advanced aircraft discovery software that analyzes multiple data sources to identify aircraft activity at local airports. Los Angeles County features several busy business aviation gateways, including Los Angeles International Airport (LAX), Van Nuys (VNY), Hollywood Burbank (BUR), Long Beach (LGB), and Hawthorne Municipal (HHR).
Since the program was launched in January 2026, the new system has identified nearly 1,000 previously unassessed aircraft. The discoveries are projected to account for nearly $2.5 billion in assessed value from prior-year escaped assessments, along with more than $1 billion in new assessments for the 2026 tax year.
Together, these assessments are expected to generate roughly $38 million in additional property tax revenue for Los Angeles County, supporting schools, cities, public safety, and other local services.
“This is a clear example of how smart technology investments can improve fairness, strengthen compliance and generate resources for the public good,” said Jeffrey Prang, Los Angeles County assessor.
Aircraft located in the state are taxed at 1.0% to 1.2% of their evaluated worth, regardless of where they are officially registered. While owners are expected to self-report these assets, the integration of automatic dependent surveillance-broadcast (ADS-B) flight-tracking technology helps officials verify tax fillings. Exemptions are granted only for aircraft in the state strictly for maintenance and repairs, or those designated as historically significant.

How Aircraft Tax Liability Is Determined
California’s property-tax rules generally focus on where an aircraft is regularly or habitually situated, rather than simply where it is registered. The California State Board of Equalization says aircraft are assessed annually at their tax situs. Temporarily moving an aircraft out of a county on January 1 does not necessarily remove its tax liability if it is regularly based there.
County assessors can use several sources to establish and aircraft’s location and ownership, including information from the Federal Aviation Administration (FAA), airport operators, other counties, the Board of Equalization, and on-site inspections. Aircraft owners can also be required to submit an annual Aircraft Property Statement, particularly when the aircraft meets the applicable reporting requirements.
