Is there anyone that actually earns a billion dollars a year?

I know Forbes releases info about people with high salaries in different fields but not everybody. Does anyone actually earn taxable income of 1 bill. Most billionaires have high net worths due to stocks owned, annuities owned, and stock options granted by their companies. Their actual annual taxable income is WAY different than their actual net worths, Warren Buffet said he makes btwn 45 - 50 mill taxable income but owns loads of stock options and other financial tools.
