California Faces Deficits After $165 Billion Revenue Estimate Error

California is grappling with chronic multibillion-dollar deficits and significant unfunded liabilities following a period of aggressive spending. The fiscal crisis stems from a $165 billion error in revenue estimates four years ago, which created a perceived $97.5 billion surplus. This mirage drove substantial spending increases, including a $6.2 billion overage for undocumented immigrant healthcare.

Gavin Newsom oversaw this spending expansion, during which the state payroll grew by approximately 100,000 positions since 2019. General fund spending reached a record high of 9.58% of total personal income in the 2023-24 period.

State Controller Malia Cohen disclosed the extent of the crisis in the 2024-25 Annual Comprehensive Financial Report issued in May. The report reveals $176.5 billion in unfunded liabilities for employee pensions and retiree benefits. These financial pressures have intensified the debate over Proposition 40, a proposed wealth tax on billionaires, as data indicates the top 1% of taxpayers generate nearly half of the state's income tax revenues.
