California Proposition 40 would impose five percent wealth tax on billionaires to fund healthcare and education

Proposition 40 seeks to impose a one-time five percent tax on approximately 200 California billionaires, potentially raising $100 billion over five years for healthcare, food assistance, and education programs. Supporters argue that the wealthiest individuals have disproportionately benefited from recent federal tax reforms and should help offset Medicaid cuts that threaten hospital closures. Opponents, including Silicon Valley entrepreneurs and business groups, contend the measure would drive billionaires out of California and ultimately reduce state tax revenues.

California's Proposition 40 represents a novel approach to state revenue generation by targeting ultra-wealthy residents specifically. The measure would apply only once, at the beginning of this fiscal year, affecting roughly 200 individuals whose net worth exceeds $1 billion. Backers contend that federal tax policy changes have created widening wealth inequality, while state-funded healthcare programs face significant reductions that threaten institutional closures and service disruptions across California.

The proposal includes contingency language: if competing ballot measures receive stronger voter support, Proposition 40 would be nullified entirely. This provision reflects a crowded ballot landscape where multiple wealth-taxation and revenue proposals compete for voter approval simultaneously, each with different funding mechanisms and policy priorities for healthcare expansion and education.
