Apple has been ordered to pay a record sum of 13 billion euros ($14.5 billion) plus interest after the European Commission said Ireland illegally slashed the iPhone maker's tax bill, in a crackdown on fiscal loopholes that also risks inflaming tensions with the United States Treasury. According to the European Union regulator, Apple benefited from selective tax treatment that gave it an unfair advantage over other businesses. In the meanwhile, Apple has refuted such accusations, saying that EU's conclusion has "no basis in fact or law." EU Competition Commissioner Margrethe Vestager said, "If my effective tax rate would be 0.05 percent falling to 0.005 percent -- I would have felt that maybe I should have a second look at my tax bill." Apple CEO Tim Cook said, "Over the years, we received guidance from Irish tax authorities on how to comply correctly with Irish tax law -- the same kind of guidance available to any company doing business there. In Ireland and in every country where we operate, Apple follows the law and we pay all the taxes we owe."
