EU antitrust regulators have ordered Apple to pay up to 13 billion euros in taxes to the Irish government. That's  after ruling that a special plan to route profits through Ireland is illegal state aid.

The sum is some 40 times bigger than the previous known demand by the European Commission to a company in such a case.

But the EU says the amount could be reduced if other countries sought more tax themselves from the U.S. tech giant. Ireland disagrees with the ruling, saying it has to seek cabinet approval to appeal.
