Proposition 13

California voters will decide on 14 ballot measures in November, including a 5% wealth tax on billionaires (Proposition 40) and countermeasures (Props 41 and 42) backed by billionaire Sergey Brin. Legislative changes in 2016 allowed sponsors to remove measures before deadlines, leading to compromises that reduced the total from 20 to 14, though conflicts like the wealth tax remain unresolved.

A measure to eliminate Los Angeles' 'mansion tax' (Measure ULA) was removed from the November ballot after a deal in Sacramento led to a substitute measure that would raise the vote threshold for special taxes. The Howard Jarvis Taxpayers Association celebrated the deal, while real estate groups expressed disappointment as existing transfer taxes remain unaffected.

The California Teachers Association (CTA) and SEIU-United Healthcare Workers West (SEIU-UHW) are competing over state budget allocations, with CTA advocating for education funding through Proposition 98 and SEIU-UHW prioritizing Medi-Cal healthcare spending. Their rivalry extends to political endorsements, with CTA supporting billionaire Tom Steyer and SEIU backing former Attorney General Xavier Becerra in the 2026 gubernatorial race.

Incumbent L.A. County Assessor Jeff Prang is facing four challengers in the upcoming election. Key issues include transparency and Proposition 13, with five candidates vying for the position.
