Think Progress � ExxonMobil paid no federal income tax in 2009.: "Exxon tries to limit the tax pain with the help of 20 wholly owned subsidiaries domiciled in the Bahamas, Bermuda and the Cayman Islands that (legally) shelter the cash flow from operations in the likes of Angola, Azerbaijan and Abu Dhabi. No wonder that of $15 billion in income taxes last year, Exxon paid none of it to Uncle Sam, and has tens of billions in earnings permanently reinvested overseas."
