California Mints Millionaires Faster Than They Can Leave

After Covid-19 arrived in 2020, a lot of wealthy people fled locked-down California. Elon Musk, the world’s second-richest human, moved to Texas, griping that the Golden State had become “a little complacent, a little entitled.” Venture capitalist Keith Rabois headed to Miami, saying that “San Francisco is just so massively improperly run and managed that it’s impossible to stay here.” Other prominent tech figures decamped for Nevada, Colorado, Wyoming and elsewhere.

It might come as a surprise, then, that the number of California residents with incomes of $1 million or more grew by 61,900, or 66%, from 2019 to 2021, according to statistics released last week by the Internal Revenue Service. Booming asset markets and pay increases sent the number of tax millionaires up sharply in every state, and their numbers more than doubled in Montana, Idaho and Utah, but California’s percentage increase was above average. Its share of US millionaires rose to 17.9% in 2021 from 17% in 2019, while those of next three most populous and millionaire-filled states — New York, Texas and Florida — fell.

Where the Millionaires Are

It’s not that the exodus of affluent Californians was a mirage. From 2020 to 2021 (more precisely, from when people filed their 2019 taxes to when they filed their 2020 taxes), 403,041 taxpayers with an average adjusted gross income of $125,362 left California for elsewhere in the US, and just 241,216 with an average income of $87,072 moved in. (The IRS will release 2021-2022 migration data in June.) But rising incomes in the state minted enough new homegrown millionaires to replace all the departers and then some.

This income bump owed a lot to the spectacular growth that California-based tech companies experienced in 2020 and 2021, and the accompanying spate of initial public offerings. The subsequent tech downturn — the Nasdaq Composite Index fell nearly 60% from late 2021 to late 2022 — means the state’s share of US tax millionaires probably fell in the 2022 tax year. Since then, though, an artificial-intelligence boom centered in San Francisco has driven Nasdaq to records, and Musk and Rabois have moved back part time (although I imagine they’ll keep their primary residences in Texas and Florida, which don’t have a state income tax). California has a long history of weathering tech ups and downs and the departure of exasperated rich people and continuing to come out on top.
