The entire list of 214 California billionaires potentially subject to California's proposed wealth tax on billionaires..

California has a lot of billionaires, more than any other state and more than most countries. So a proposed wealth tax on its billionaires could be a windfall, if they stick around. Under the Billionaire Tax Act, California residents worth over $1 billion would face a one-time tax totaling 5% of their assets. If the tax plan receives enough signatures, it will appear on the ballot in November and, if passed, would apply retroactively to billionaires living in the state as of January 1. The tax would be due in 2027, with the option to spread the payment out over five years, with interest.

Of particular note to Democrats, one of the Democratic candidates for California Governor - Tom Steyer - himself a billionaire, has indicated that he is favor of the proposed wealth tax, that he will vote for the tax and that he will pay it.

If every one of the California's billionaires paid the proposed wealth tax, in excess of $109 million would be raised to backfill federal funding cuts for Medi-Cal, healthcare services, and social safety nets. However, several of California's billionaires have preemptively left the state to avoid the proposed wealth tax. They include the following:

Larry Page Google $261,809,000,000
Sergey Brin Google $241,572,000,000
Mark Zuckerberg Facebook $226,702,000,000
