"Proposition 30, approved by voters in 2012, provided critical revenues to California at a time when the state faced daunting budgetary challenges. Prop. 30’s tax rate increases are scheduled to fully expire at the end of 2018. Prop. 55, which will appear on the November 8, 2016 statewide ballot, would extend for 12 years the Prop. 30 tax rate increases that affect very-high-income Californians. Revenues generated by Prop. 55 – a projected $4 billion to $9 billion per year from 2019 through 2030 – would go to K-12 public schools, community colleges, health care for low-income Californians, the state’s rainy day fund, state debt payments, and other state services. This Issue Brief provides an overview of Prop. 55 and the policy issues it raises. The California Budget & Policy Center neither supports nor opposes Prop. 55."
