This document provides a summary and analysis of California's current tax system. It discusses four key characteristics: volatility, predictability, sufficiency, and progressivity. The current system is highly volatile as it relies heavily on personal income taxes, which are more sensitive to economic swings than other taxes like sales and property taxes. Revenues are also difficult to predict accurately. While the tax structure currently generates sufficient revenue, it may not keep pace with rising state costs. The system is progressive, with tax burden increasing as income rises. Reform aims to improve fiscal management and encourage economic growth by addressing these issues.
