Elon Musk, the world’s richest person, has tweeted he will pay $11bn (£8.3bn) in tax for this year.
Mr Musk has been embroiled in a public debate on social media over how much tax he pays.
Earlier this week, Democratic Senator Elizabeth Warren tweeted that Mr Musk should stop “freeloading off everyone else”.
“For those wondering, I will pay over $11bn in taxes this year,” the billionaire responded.
Mr Musk, co-founder of electric car maker Tesla and aerospace manufacturer SpaceX, became the world’s richest person earlier this year.
Bloomberg Billionaires Index puts his wealth at $243bn, while Tesla is worth around $1tn and SpaceX is worth $100bn.
Last week, Mr Musk was named Time Magazine’s Person of the Year.
That prompted Senator Warren to tweet: “Let’s change the rigged tax code so ‘The Person of the Year’ will actually pay taxes and stop freeloading off everyone else.”
