Back in 2016, the European Commission ordered Apple to pay Ireland around 13 billion euros ($15.3 billion at current exchange rates) in back taxes. Apple had a special sweetheart deal with Ireland, which the commission ruled was illegal. Neither party was happy with this decision. Apple argued that the amount owed was miscalculated, while Ireland believed that the EU overstepped the bounds of its authority, but appeals so far have been unsuccessful. Now, according to Reuters, Apple has begun paying the owed back taxes.
