Obamas Paid 20.5 Percent Tax. That’s on the couple’s $789,674 in 2011Income. Obama, who earns a $400,000 annual salary as president,received most of the rest of his 2011 income from sales of his books.Because they earned less than $1 million in 2011, the Obamas wouldn’tbe subject to the Buffett rule, the proposed minimum tax for highearners the president has been pushing for in his re-electioncampaign.The Obamas’ charitable donations were a significant percentage oftheir income for 2011, and it’s a big reason why their tax rate islower than many households with incomes in that range.
