Elon Musk revealed on Twitter Sunday night that he will pay over $11 billion in taxes this year.

The Tesla and SpaceX CEO, who is the world’s richest person, tweeted, “For those wondering, I will pay over $11 billion in taxes this year.”

The estimate comes at the end of a year in which the billionaire’s tax contributions have been heavily scrutinized — amid public spats with progressives in Congress, during consideration of a billionaire tax to fund the Democrats’ social agenda, and after Time magazine named him “Person of the Year”.

June ProPublica report estimated that Musk paid $68,000 in federal income taxes in 2015, $65,000 in 2017 and none in 2018.
