The chart below from the Tax Policy Center shows the distribution of federal income taxes paid by income level in 2011.
It contains a number of interesting factoids, including the following:
7,000 people made more than $1 million but paid no income tax.
22,000 people made between $500,000 and $1 million but paid no income tax.
81,000 people made between $200,000 and $500,000 but paid no income tax.
381,000 people made between $100,000 and $200,000 but paid no income tax.
So that's 491,000 Americans who made more than $100,000 a year who paid no income tax. (Clearly dependent victims who refuse to take responsibility for their lives!)
