California Proposition 41 would require pre-election financial and performance audits by the State Auditor for citizen initiatives proposing new special taxes once they reach 25% of required signatures, mandate recurring four-year reviews for programs funded by special taxes enacted after January 1, 2026, and bar such revenues from exclusion under the voter-approved Gann spending limit. These provisions directly target measures like the competing Proposition 40 wealth tax on the same November 3, 2026 ballot, potentially nullifying it if 41 receives more votes. Trader consensus around a narrow No lean reflects uncertainty over whether added procedural requirements and spending accountability rules will gain majority support amid broader debates on revenue flexibility versus program efficiency. No major late shifts have altered the closely balanced positioning in the final weeks before voting.
