**California voters will decide in November 2026 whether to make permanent the higher personal income tax rates on high earners first approved in 2012 and extended in 2016.** The measure, which qualified for the ballot in June 2026 after education groups submitted well over the required signatures, locks in rates applying to single filers above roughly $360,000–$371,000 (adjusted for inflation) and directs the resulting $5–15 billion in annual revenue primarily to K-12 schools and community colleges. Strong support from the California Teachers Association and allied unions, combined with the tax’s established role in education funding and voters’ prior approval of similar extensions, underpins the 72.5% implied probability for passage. The proposal faces limited organized opposition relative to competing wealth-tax measures and benefits from its framing as preserving existing revenue streams rather than creating new taxes. Resolution occurs after the November 3, 2026, election once official results are certified.
