California Proposition 42, which would bar new state personal property taxes and certain retroactive taxes enacted after January 1, 2026, sits in a near tie because it directly counters the concurrent wealth tax initiative on the November ballot. If both measures pass, the one receiving more votes prevails, sharpening the contest over revenue generation versus protections for retirement holdings, personal assets, and savings. Business organizations and taxpayer groups back the prohibition to limit future tax authority, while supporters of expanded state funding argue it would constrain fiscal options amid competing spending priorities. Recent legislative efforts at the federal level to address retroactive taxation and ongoing campaign positioning have kept probabilities balanced, with shifts likely hinging on polling trends, total spending by opposing coalitions, and voter responses to broader economic conditions before Election Day.
