As expected, the European Commission today officially announced an investigation into Apple’s tax practices in Ireland. The EU is checking whether the deal, along with separate deals made by Starbucks and Fiat, qualifies as illegal state aid, Bloomberg reports. “Apple pays every euro of every tax that we owe,” Apple responded in an e-mailed statement. “We have received no selective treatment from Irish officials. Apple is subject to the same tax laws as scores of other international companies doing business in Ireland.” Ireland’s Finance Ministry is “confident” that no state aid rules were breached.
