Under Proposition 13, California properties are only reassessed upon a change in ownership or completion of new construction.

Proposition 13 caps property tax at 1% of assessed value, limits annual increases to inflation or 2%, and ties assessed value to purchase value, not market value.

Business personal property and fixtures are valued annually as of the January 1 lien date.

San Francisco County
A convergence of finance, tech, healthcare, and creativity, the County of San Francisco is a culmination of diverse, powerhouse industries. While physically fairly small, the estimated GDP for San Francisco is more than $263 billion and serves as a key international trade and business hub, specifically between the U.S. and the Pacific. The County of San Francisco allows business access to a diverse and educated workforce, unparalleled venture capital funding, and exceptional opportunities for tech growth and innovation. However, there are high costs and tax considerations.
Business Property Classification: Business personal property is reassessed annually. Assessment begins with the cost of the asset, including sales tax, freight, and installation.
Implication for Business Taxes: Businesses operating in San Francisco must file a business personal property statement for taxable assets. Other taxes might include a vacancy tax and gross receipts tax. There is also a mansion tax for any real property more than $5 million.
Los Angeles County
With a GDP of nearly $1 trillion, Los Angeles County is the single most economically powerful county in the United States. With more than 9.7 million residents, Los Angeles County is characterized by its rich culture, piloted by Hollywood’s global arts and entertainment industries. The county is also a hub for international trade, housing the Port of Los Angeles and the Port of Long Beach, the busiest container port complex in the Western Hemisphere. Los Angeles offers businesses unrivaled access to global markets and talent but also comes with some of the highest property tax implications in the country.
Business Property Classification: Business personal property is reassessed annually. Businesses with personal property costing more than $100,000 must file a Business Property Statement by April 1 annually.
Implication for Business Taxes: Areas such as West Los Angeles and South Bay have seen more stability because of concentrations of media, tech, and logistics industries, whereas areas with concentrations of office and entertainment sectors have seen growth slowing. In Los Angeles County, businesses must account for local transfer taxes, municipal-level taxes, and more, including a mansion tax for any real property worth more than $5 million.
Santa Clara County
Home to Silicon Valley, Santa Clara County is the epicenter of technology and innovation in the United States. From leading companies, like Apple, Google, and Intel, to accelerating startups, the Santa Clara area continues to draw in global visionaries, creating endless opportunities for economic growth. For businesses, the unparalleled access to capital and global influence is often challenged by the county’s costly property tax structure.
Business Property Classification: California property is appraised annually based on cost of all supplies, equipment, fixtures, improvements, and land owned at each location within Santa Clara County.
Implication for Business Taxes: Despite COVID-era growth, industries have largely leveled out, with some having seen decreased demand, like life sciences and tech. The office market has also seen increased vacancy rates because of high costs compared to other counties. Locality plays a large role in operational costs and market resilience. With high-tech properties and assets always evolving and innovating, it is imperative to review and ensure that values for personal property are accurate.
San Diego County
With a long-standing legacy as a critical anchor for the nation’s defense and homeland security, San Diego County has become one of the most economically diverse counties in the state. Since the mid-20^th century, San Diego has built a world-class biotechnology and life sciences industry, supported by leading research institutions, such as UC San Diego, and private medical technology companies. While many businesses in San Diego County benefit from the county’s rich economic landscape, rising real estate values and property tax implications remain a key factor in operating costs.
Business Property Classification: All business property is assessed annually, and Business Property Statements must be filed by April 1.
Implication for Business Taxes: While the county experienced large growth during COVID, that growth has slowed and may continue to trend downward in coming years. Industries such as life sciences have been heavily impacted, while the office market is one of the largest in the state. Locality plays a major role in business health; for example, currently, University Town Center is better off than Downtown. Additionally, local taxes, such as transfer taxes and business tax increases, are subject to change and can impact cost of operations significantly.
