Increases funding for K-12 public schools, community colleges, and local governments by requiring that commercial and industrial real property be taxed based on current market value. Exempts from this change: residential properties; agricultural properties; and owners of commercial and industrial properties with a combined value of $3 million or less. Increased education funding will supplement existing school funding guarantees. Exempts small businesses from personal property tax; for other businesses, exempts $500,000 worth of personal property. Summary of estimate by Legislative Analyst and Director of Finance of fiscal impact on state and local governments: Net increase in annual property tax revenues of $7.5 billion to $12 billion in most years, depending on the strength of real estate markets. After backfilling state income tax losses related to the measure and paying for county administrative costs, the remaining $6.5 billion to $11.5 billion would be allocated to schools (40 percent) and other local governments (60 percent).
