The idea that America's 35 percent corporate tax rate is stifling U.S. economic growth is almost an article of faith among some politicians.
The sound bites from Republican presidential debates to campaign stops are basically interchangeable: "We need to bring that corporate tax rate down."
But in fact, very few corporations pay taxes on 35 percent of their profits. With the help of complex international tax loopholes, some companies manage to pay almost no corporate tax at all.
