Could the upper quintile pay the annual federal personal income tax for all other quintiles from their annual income? I am wondering if, in theory, the upper quintile (20% of earners in the U.S.)  could pay the annual federal tax bill for all quintiles from their annual income?
I have been looking at 2013 CBO data  here  that shows quintile income as a percentage of total income and quintile taxes paid as a percentage of total taxes paid. What's necessary is the amount of total income and total federal taxes paid - does anyone know these values?
Here is the latest report of the Congressional Budget Office on federal taxes by households. The main result you are looking for is this one (page 31):



The "Federal Taxes" row shows that the upper quintile tax bill is higher than the tax bill of the other four quintiles combined. (the data are averages but each quintile has same number of households so those numbers are enough to conclude this).

The figure below show this more clearly, in percentage terms:

 

Check here for older reports.

PS: amazingly, the top quintile gets more government transfers than the poorest quintile, which get the lowest. An entirely regressive system!
