Proposition 41 on the Nov. 3 ballot pairs two changes: new audits of programs paid for by special taxes, and a rule that new special taxes count against the state's spending cap. That second piece is what puts it on a collision course with Proposition 40, the proposed tax on billionaires' wealth.
The audits
Special taxes are taxes tied to a set purpose, such as fuel taxes that can only go to roads. Under Prop. 41, once backers of a special-tax initiative gather a quarter of the signatures they need, the state auditor would have to review the program the tax would fund, including ways it could trim its yearly costs by 10%, according to the Legislative Analyst's Office.
If the initiative qualifies, a summary of that audit would go into the voter guide mailed to every household.
Programs funded by special taxes that the Legislature or voters create or raise after Jan. 1, 2026, would also be audited every four years. New tax revenue would pay for the audits when a tax passes; the state's General Fund would cover reviews of proposals that fail or never reach the ballot.
The LAO puts the auditor's added costs in the low millions of dollars a year, rising over time, plus a few hundred thousand dollars in printing and mailing for each qualifying initiative. It says the overall effect on state finances cannot be known and depends on what policymakers do with the auditor's advice.
The spending limit and Prop. 40
The state's spending cap, often called the Gann Limit after the anti-tax activist behind the 1979 measure that created it, exempts some kinds of spending. Prop. 41 would stop new taxes from leaving their revenue outside it.
Prop. 40 does exactly that, and according to the CalMatters guide republished by LAist, if both pass and Prop. 41 gets more votes, Prop.
40 is canceled. Prop. 42, which bars new state taxes on financial assets and most retroactive taxes, works the same way against Prop.
