California Proposition 41: Require audits of new special taxes and keep them under the spending limit
What it does. Proposition 41 would prohibit new state taxes that exclude their revenues from the state spending limit approved by voters in 1979. For statewide special taxes, it would require a State Auditor review of the programs that would receive money from a voter-proposed special tax (after supporters gather 25 percent of the needed signatures), with a summary printed in the voter guide if the measure qualifies, and repeat audits every four years of programs funded by special taxes created after January 1, 2026. It also says other voter-approved measures on the same ballot are void if they conflict with it and it receives more yes votes. [1] [2]

If you vote yes
A YES vote on this measure means: When special taxes are proposed by voter initiatives, the California State Auditor would review programs funded by the tax before the initiative appears on the ballot. The California State Auditor also would regularly review programs funded by special taxes approved by voters or the Legislature. In addition, the state might not be able to exclude any new special tax spending from its spending limit. [1] [2]
If you vote no
A NO vote on this measure means: The California State Auditor’s responsibility to review government programs would not change. The state spending limit requirements would not change. [1] [2]
What it would cost
The Legislative Analyst estimates an unknown net fiscal effect. State Auditor costs would increase, “in the range of the low millions of dollars per year but would grow over time,” and would mostly be paid from the revenues of the new special taxes. Printing audit summaries in the voter guide could add “a few hundred thousand dollars per qualified initiative.” There could be savings if the Auditor’s recommendations are implemented, but they “are not known.” [1]
Both sides
Strongest case for
The official argument in favor was signed by leaders of the California Society of CPAs and the California Taxpayers Association and by a former State Auditor. It says “Before we vote on new taxes to fund programs, voters should have access to independent information about how those programs are being managed and whether they actually need more funding.” [2]
It says “This year alone, California’s state government will spend more than $350 billion—a 79% increase in spending since 2019,” with “too little to show for it” from programs such as homelessness efforts, and that audits would help “identify areas of waste, fraud and abuse.” [2]
It argues that “Prop. 41 doesn’t raise taxes—it protects taxpayers’ interests,” and that it “Requires all taxes to comply with the state’s voter-approved spending limit—including its requirement that excess revenues get refunded to taxpayers.” [2]
Strongest case against
The official argument against was written by Suzanne Jimenez of SEIU-United Healthcare Workers West. It says “This is a billionaire-funded initiative designed specifically to undo the California Billionaire Tax, Prop. 40,” and that “Prop. 41 isn’t about auditing new taxes. It’s about defeating one specific tax that billionaires want to avoid.” [2]
It names Sergey Brin as “One of Prop. 41’s main funders” and says he has spent “over $57 million to fund sham measures like Prop. 41 that attempt to cancel out a billionaire tax.” [2]
Its rebuttal says Prop. 41 was “created to trick voters like you into making a billionaire tax impossible to enforce,” would “cost the state time and money,” and that the Billionaire Tax is needed to fund healthcare, public education and food assistance. [2]
What neither side is saying
Context that bears on what this measure does or who it affects but that the arguments above do not address. These are sourced facts, not arguments for or against the measure.
- It could stop Proposition 40 from taking effect. The Legislative Analyst says that if Proposition 41 receives more yes votes than Proposition 40, “then Proposition 40 could be stopped from becoming law even if it gets yes votes from a majority of voters,” because courts could find the two conflict. [1]
- Details of the audit rules. The audit would take place after supporters collect 25 percent of the signatures needed, “which is before it is known whether the initiative will qualify for the ballot.” The Legislative Analyst says the audits would include “identifying ways to reduce an audited program’s annual costs by 10 percent,” and that the one-time cost of audits for special taxes that do not reach the ballot or are rejected would be paid from the state’s General Fund.
