Legislature Amendment Threat

Senator Bernie Sanders toured California in early October 2026, holding rallies in San Francisco and Bakersfield.
Critics warn the initiative grants the Legislature authority to amend the tax, potentially expanding it beyond billionaires and necessitating a constitutional amendment.

Blindspot

Critics argue that Proposition 40 would give the California Legislature authority to amend the one-time billionaire tax, potentially expanding it beyond billionaires, a change that experts say would require a constitutional amendment.
Within this story's sources, this constitutional-amendment concern appears mainly in Left-leaning coverage and receives less attention in Center-leaning coverage.

History

Historical Context

In November 2012 California voters approved Proposition 30, a 1 % surtax on incomes above $250,000 that Governor Jerry Brown championed, delivering roughly $5 billion in annual education revenue (FY 2013-14). The measure’s temporary taxes expired, but its income-tax component was extended by Proposition 55 in 2016. Today’s Proposition 40 echoes that model by proposing a one-time 5 % levy on billionaires, reviving the debate over voter-initiated taxes.
