Who Pays Taxes In The United States

So, a lunchtime conversation about stuff led me to re-researching these numbers.

According to Tax Foundation: 

http://taxfoundation.org/article/summary-latest-federal-income-tax-data

In 2011, the top 10 percent of taxpayers 

(with AGIs above $120,000) accounted for 45.4 percent of all AGI and 68.3 percent of all income taxes paid.

Taxpayers in the top 5 percent accounted for 33.9 percent of all AGI and 56.5 percent of all income taxes paid.

The top 1 percent of all taxpayers accounted for 18.7 percent of all AGI and 35.1 percent of all income taxes paid.

A more Democrat leaning group puts it this way: 

http://www.cbpp.org/cms/?fa=view&id=3505 

In fact, when all taxes (state, local, excise) are considered, the share of taxes that each fifth of households pays is similar to its share of the nation’s total income.[22]  

ITEP data show that in 2011,

the bottom fifth of households received 3.4 percent of the total income in the nation and paid 2.1 percent of the total taxes. 

The middle fifth of households received 11.4 percent of income and paid 10.3 percent of taxes. 

The top 1 percent of households received 21.0 percent of income and paid 21.6 percent of taxes.  The tax system as a whole is only mildly progressive.[23]

(don't you like how they use "received" instead of "earned?")

In brief, from the IRS itself: http://www.irs.gov/uac/SOI-Tax-Stats-Individual-Income-Tax-Rates-and-Tax-Shares#_article 

This is from Table 7, near the bottom of the page. It's not apples to apples to the numbers above, as it's using something called "1979 Income Concept" Income Excluding Dependents (Finding this info is a nightmare, so go for it if you don't believe me).

Total income tax share (percentage):	Total	Top 1 percent	Top 5 percent	Top 10 percent	Top 25 percent	Top 50 percent

Income share (percentage):	Total	Top 1 percent	Top 5 percent	Top 10 percent	Top 25 percent	Top 50 percent
