President Obama and First Lady Michelle Obama paid $112,214 in federal taxes on $608,611 in income last year for a tax rate of 18.4 percent, which is slightly lower than the average rate paid by others in their income bracket. Most American households making between $500,000 and $1 million paid a 20.6 percent rate in 2012, according to the nonpartisan Tax Policy Center. In spite of the lower tax rate, the Obamas still managed to overpay taxes last year to the tune of $16,815, according to their tax returns, which were released by the White House on Friday.
