President Obama and the First Lady have released their 2010 federal income and gift tax returns and the White House blog has the goods. Their adjusted gross income is $1,728,096, most of it made from the president's books. Their total federal tax burden was $453,770, for an effective tax rate of 26 percent, which is about average for the top quintile and slightly below average for a millionaire. The president got a considerable tax break from donating a seventh of his income to charity.
