Google on the term: “Exxon-Mobil paid no 2009 US income taxes”.
...Exxon did indeed pay substantial income taxes to the U.S. Treasury in 2009, and that it overpaid taxes in 2008.
...mistake was in thinking that these figures somehow reflected actual tax benefits and liabilities. So what we should have written was that ExxonMobil “recorded” no U.S. income taxes for 2009 instead of “paid.”
...And for all you commenters outraged that Exxon isn’t paying taxes in the U.S., don’t worry, it is. Our article only focused on income taxes, but it’s worth noting that the 10-k also records $7.7 billion in other taxes in the U.S.
