Limits on personal property and retroactive taxes

What would change?

Prohibits new state taxes on owning or controlling personal property, including financial assets, and generally prohibits certain retroactive state taxes. It applies to covered taxes enacted or effective on or after January 1, 2026. It does not repeal existing income taxes or establish a new benefit payment.

Where money goes.
Who controls it.

Public funding and campaign donations are separate. Where this measure creates no new funding pool, the table explains the budget authority or restriction instead.

Flexibility, exceptions, and possible diversion

There is an exception for a legislative statute with retroactivity of no more than 365 days when the Governor declares a qualifying disaster or fiscal emergency and the statute restricts the revenue to that emergency. The retroactivity prohibition is therefore not absolute. The legal-defense appropriation is authorized spending outside the headline tax-protection promise.

Oversight and accountability limits

Tax limitations are enforced through lawmaking and potentially litigation, rather than a new fund audit. Defense counsel qualifications and a written commitment must be checked, with the written commitment available on request. Future laws and court interpretations determine the actual reach of the restrictions.

No actual expenditure inconsistent with this proposed law has been established here. Authorized administration, exceptions, or legal-defense costs are disclosed separately from headline benefits. Future appropriations, transfers, contracts, waivers, and audit findings must be checked before calling an expenditure misuse.

Who may benefit.
Who may bear costs.

Support and opposition.

Supporters listed in the official guide: CA Professional Firefighters; State Building & Construction Trades Council of CA; AMVETS Department of CA.

Opponents listed in the official guide: US Senator Bernie Sanders; SEIU United Healthcare Workers West.

“None submitted” describes that guide field. It does not establish the absence of supporters, opponents, campaigns, or contributions. An endorsement, argument signature, and donation are distinct evidence.

Complete submitted arguments and rebuttals

The official submissions appear below, as the authors’ opinions. Their claims are not verified by the state. An individual’s affiliation does not by itself establish an organizational endorsement.

Check competing claims.

These checks explain comparisons and qualifications; they are not a truth score for every campaign assertion.

Messages and emotional appeals.

Messages are attributed to the linked campaign or official submission. Emotional appeals are Ballot Lens interpretations of persuasion techniques, not findings about motives.

Who funds the campaigns?

Power Search contribution records through Oct 9, 2026 · 35 reconciled records · retrieved Oct 11, 2026. These are receipts, not expenditures or public-program allocations.

Supporting and opposing committees: who they are

A recipient committee raises or receives funds for political activity and files public reports. A primarily formed ballot-measure committee campaigns for or against a particular measure; other committees can have wider purposes. Names and reported positions do not establish a complete membership list or every named group’s endorsement.

Power Search measure-associated receipts and Quick Guide adjusted primarily formed committee totals use different coverage. A zero in one source is not proof of no spending. Multi-measure committee totals must not be added across propositions.

Who proposed it?
How does it connect?

The Attorney General identifies Kurt R. Oneto as proponent. This constitutional initiative qualified through petition signatures.

Qualified for California’s November 3, 2026 ballot; not yet approved by voters. Proponents, legislative authors, endorsers, argument signatories, and committee officers have different roles.

Proposition 40 could be prevented from taking effect if 42 also passes with more yes votes and a court finds a conflict. This is a conditional legal interaction, not an automatic result.

Ready for your review.

All assessments remain research drafts awaiting human editorial review. The following measure-specific items need attention:

• Review emergency exceptions, the scope of indirect ownership taxes, and any Proposition 40 litigation.
• Shared committee receipts are not unique dollars across measures.

Across all measures, original finance filings and amendments, expenditures, indirect funding, litigation, and actual spending compliance remain outside the verified dataset. Predictions are conditional. This assessment does not certify future conduct.
