49% !
And 30% get more back than they paid in via the Earned Income Tax Credit--a bulls*** euphemism for welfare if there ever was one.
Income tax liability for 2009
PDF Link to letter from the Joint Committee on Taxes to the Congress about half way down.
"Joint Committee", that means both houses, and that means in today's Congress, both parties.
49% -- That's a percentage, but not the answer to "How many Americans pay income tax?"
I actually was trying to figure that out a few days ago, and discovered that our elevated and -- thanks to Obama! -- now tricked out Census Bureau does not deal in 'actual numbers' but all the figures that they publish lately are called 'estimates'. Thus, even after the bout of stimulus hiring, to fulfill the new duties and contend with the new reporting requirements when conducting a census, none of the work performed has done anything to increase the accuracy of the count, nor has it enabled anyone to say, with certainty, just how many people are in the United States, or, for that matter, just how many of those people are American, or how many of those Americans pay income tax... They've got data, posted and downloadable, on their web-site, but what I saw was always labeled "estimate", as in 2009CensusEstimate. I think that you could estimate the number of Americans by subtracting from the TotalPopulationEstimate the number listed in the column of InternationalMigrationsEstimate, but I can't be sure, because it's a spreadsheet of data, no formulas...
It is still too early to obtain complete data for 2010, but it is still just an estimate.
