i doubt it will be published anytime soon as it will be another embarrassment for obama....usually by now we find out what % of the people paid no income tax for the previous year...when was the last time during obama’s reign of error we’ve received a number on the % of people who pay no federal tax???
I did a quick look for articles that cited this data, and it's spread all over last year. So, I'm not sure exactly when the new data was released.
On the IRS website, the Excel workbook that was used to generate this graph was last modified on 2011-10-03. But, it doesn't have that particular detail.
