Our federal income tax code is progressive and has different tax rates based upon income brackets. More you make, the more taxes you pay. So just who pays the most and how much of the federal income taxes collected by the U.S. government?

HowMuch.net had the answer:

The richest percent of Americans, pay 39.5% of all Federal Income Tax. That is one of the most eye-catching figures in a study released by the Tax Foundation earlier this month. To put that percentage in absolute figures: the richest percent of American taxpayers pay in $542.64 billion of a total take of Federal Income Tax of $1.37 trillion.
