Forbes Warren Buffett's Secretary Likely Makes Between $200,000 And $500,000/Year to pay higher tax than boss

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 Buffett’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 Buffett must pay Debbie Bosanke a salary above two hundred thousand
