Valuation Date
Billionaires' net worth assessed on this date for the one-time 5% tax.
Sergey Brin has put $102 million behind Proposition 41 and 42, companion ballot measures that could nullify California's proposed wealth tax, Proposition 40. The November 2026 vote sets up a significant direct-democracy and constitutional test over how states may tax billionaire net worth.
Google co-founder Sergey Brin's $102 million campaign against California's billionaire wealth tax is a masterclass in legal and procedural countermeasures. Facing a $13.3 billion liability, Brin funded competing ballot initiatives that create constitutional and administrative hurdles, raising questions about direct taxes, state property tax caps, and the enforceability of a net worth levy.
A November ballot measure imposing a one-time 5% net-worth tax on California billionaires sets up a high-stakes legal battle over state and federal constitutional limits. Domicile definitions, uniformity clauses, and dormant Commerce Clause challenges could stall implementation even if voters approve. Legal experts are already dissecting the proposal’s vulnerabilities, with opponents preparing litigation strategies.
