2013 Federal Government spending: 3.5 Trillion Dollars
2013 Gvt. spending as a percent of GDP: 20.83 percent

The absolute tax rate on every dollar of economic activity in the US would have to be 20.8% to balance the budget.

Perhaps the rate can be lowered a bit by double taxing dividends. Ten percent is a pipe dream.
