Warren Buffett has called himself mega-rich, but now he's revealing how much money he made last year: US$62,855,038 ($79 million).
In a New York Times opinion piece Buffett revealed that he paid US$6,938,744 in federal taxes last year, or 17.4 per cent of his taxable income.
Buffett has said that tax rate is too low compared to middle-income wage earners, especially as President Barack Obama and Congress struggle to control the mushrooming federal debt.
Obama has used Buffett as an emblem in his fight to clamp higher taxes on the wealthy, a drive that Republicans oppose.
Buffett's taxable income which subtracts exemptions and itemised deductions was US$39,814,784.
