The IRS data used for these graphs is current through tax year 2009, which includes the first year of Obama. It was published in July, 2011. Hopefully, the 2010 update will be published soon.
The CBO data lags even farther behind -- but that is significantly more complex. The data current through tax year 2007 was published in June, 2010. I keep hoping they will publish an update, but I suspect the CBO has been busy with other things.
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???
