Kind of obvious.
New York and California lost over $90 billion in income to low-tax states during Covid
New York and California lost over $90 billion in income during Covid as taxpayers moved to other states, accelerating the trend of high-earners relocating to lower-tax areas.
New data from the Internal Revenue Service shows that New York state lost $25 billion in adjusted gross income due to outmigration in 2021, on top of $20 billion lost in 2020. California reported a net loss of $29 billion in 2021, following a loss of $18 billion in 2020. Combined, the two states lost $92 billion across the two years.
The data shows that the income flight from high-tax states to low-tax states, which has been happening for years, picked up steam during Covid. The income losses for California and New York in 2021 were more than three-times their combined losses in 2019, before the pandemic took hold in the U.S.
