**Proposition 43 on California's November 3, 2026 ballot would extend the existing two-thirds voter approval requirement for local special taxes to those placed via citizen initiative, effective January 1, 2027, closing a gap created by court rulings that had permitted simple-majority passage for voter-initiated measures.** This legislative constitutional amendment emerged from a June 2026 compromise between state leaders and the Howard Jarvis Taxpayers Association, which withdrew a broader initiative that included retroactive effects and tighter limits on charter-city transfer taxes. Local government associations, service advocates, and Democratic lawmakers have opposed the measure, arguing it would hinder funding for targeted programs like public safety, housing, and infrastructure by raising the bar for citizen-driven proposals. With the election approaching, trader consensus favoring rejection at 63.5% reflects polling signals and the political difficulty of imposing supermajority thresholds on local revenue initiatives amid concerns over service delivery.
