How dependent is state revenue on a small group of taxpayers?
Core argument: In 2022, California's top 1% of taxpayers — about 170,000 payers — paid roughly 40% of the state's personal income tax revenues, payments that are highly contingent on unpredictable capital gains.
In 1957, Fairchild Semiconductor, the company that spawned Silicon Valley, was formed by eight men — only one of whom was born in California. At the start of that decade the state’s population was about 10.5mn and only about 11% of its revenue of $1.1bn came from personal income taxes. The sales and use tax (levied on products not services) accounted for almost 60%. Today, California’s population is about 39.5mn while its budget is about $320bn (not including the $174bn the state receives from Washington for social welfare programmes). Since 1990, the budget has grown at an average rate of 6% a year. Compared to the 1950s, the source of the state’s revenue has entirely flipped. In recent years personal income taxes have contributed more than 60% of the total. This revenue rests on a foundation of jelly. In 2022, the top 1% of California taxpayers — just 170,000 payers — coughed up about 40% of all the state’s personal income tax revenues. Worse still, these payments are highly contingent on unpredictable capital gains.
