Untaxed foreign profit: $31.6 billion
Cisco is leading the effort to convince Congress to pass a tax holiday for repatriated income. The company's CEO, John Chambers, co-authored an op-ed published in the Wall Street Journal arguing for it, and he recently told 60 Minutes that the company had nearly $40 billion overseas that would be brought back to the U.S. if the corporate tax rate were lower.
In fact, 50% of Cisco's sales are outside the U.S. and that's only going to grow -- IDC estimates that 71% of total information and communications technology spending will be outside the United States by 2014.
