FILE – In this Feb. 5, 2013, file photo President Barack Obama leaves the White House briefing room in Washington, where he asked Congress to come up with tens of billions of dollars in short-term spending cuts and tax revenue to put off the automatic across the board cuts, set to kick in March 1. With Washington gridlocked again over whether to raise taxes on wealthy families, it turns out they are already are paying some of their biggest federal tax bills in decades. A new analysis shows that average tax bills for high-income families have rarely been higher since the Congressional Budget Office began tracking the data in 1979, and that middle- and low-income families aren't paying as much as they used to.
