Fox News host Bill O'Reilly falsely suggested that President Obama's proposal to let Bush tax cuts expire could leave some wealthy Americans paying 40 percent of their incomes in federal taxes. But Obama has only proposed letting taxes on the top income bracket increase -- which means only income over $200,000 would be affected -- and very few Americans pay more than 35 percent in U.S. taxes.

This tax discussion comes as the Obama administration and the Republican House try to reach a deal on the automatic tax hikes and spending cuts known as the fiscal cliff.

O'Reilly told guest Adam Corolla that "your state's up to about 14 percent state income tax. President Obama wants to raise it up to about 40 percent federal. That's 54 percent. If he knocks out the deduction for state income taxes, which he wants to do, you'd be paying 54."
