ACA 22 California Assembly · 2025-2026 Regular Session

A resolution to propose to the people of the State of California an amendment to the Constitution of the State, by adding Section 4.5 to Article XIII A thereof, relating to taxation.

Summary

The California Constitution conditions the imposition of a special tax by a local government upon the approval of 23 of the voters of the local government voting on that tax, and prohibits these entities from imposing an ad valorem tax on real property or a transactions or sales tax on the sale of real property. The Supreme Court of California interpreted this provision and other provisions restricting the authority of local governments to impose, extend, or increase taxes as not restricting the authority of voters to impose taxes via initiative. This measure would, beginning January 1, 2027, prohibit a local government, including the electorate of a local government exercising the initiative power, from imposing, extending, or increasing any special tax, except as provided, unless and until that tax is submitted to the electorate and approved by a 23 vote. The measure would prohibit a local government, including the electorate of a local government exercising the initiative power, from imposing ad valorem taxes on real property, except as provided pursuant to specified constitutional provisions.

MINOR

This is an administrative transition from the enrolled version to the chaptered version of Assembly Constitutional Amendment No. 22. The substantive policy text of the proposed constitutional amendment (adding Section 4.5 to Article XIII A, restricting local government and voter-initiated special taxes and ad valorem property taxes) is unchanged. The differences are limited to formatting: the header was replaced with the standard state authentication block, a chapter number (Resolution Chapter 132) and filing date were added, page numbers shifted, and line breaks were reformatted.

TECHNICAL

Header changed from enrolled form (with adoption dates and clerk/secretary signatures) to chaptered form with 'STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL' and 'RESOLUTION CHAPTER 132'

Filing date added: '[Filed with Secretary of State June 25, 2026.]'

Page numbers changed from 98 to 97 and page header format updated to 'Res. Ch. 132'
