**Proposition 43, a legislatively referred constitutional amendment on the November 2026 ballot, would require a two-thirds voter approval for citizen-initiated local special taxes—aligning them with government-referred measures—and include related property tax restrictions.** Recent polling from the Public Policy Institute of California shows only 39% support for the local tax limitations among likely voters, with deep partisan divides. The measure emerged from a June 2026 legislative compromise after the Howard Jarvis Taxpayers Association withdrew a stricter initiative, drawing backing from taxpayer protection groups while facing opposition from organizations focused on funding schools, transit, housing, and emergency services. In a state where Democrats hold supermajorities and many local revenue measures historically pass with simple majorities, the implied probability favoring rejection reflects the competitive environment and limited early momentum for raising the threshold. The election remains the key resolution point.
