Here's an analysis in Forbes magazine about how much $$$ Bosanek makes -
The IRS publishes detailed tax tables by income level. The latest results are for 2009. They show that taxpayers earning an adjusted gross income between $100,000 and $200,000 pay an average rate of twelve percent. This is below Buffet’s rate; so she must earn more than that. Taxpayers earning adjusted gross incomes of $200,000 to $500,000, pay an average tax rate of nineteen percent. Therefore Buffet must pay Debbie Bosanke a salary above two hundred thousand.
There's another factor - Bosanek has worked for Buffett for 19 years. How many shares of Berkshire Hathaway stock and stock options does she have? She's almost certainly a multi-millionaire.
