The €13 billion in back taxes that Apple Inc. needs to pay to Ireland, as earlier computed by the European Commission, is unlikely to change, Reuters reported Feb. 2 citing a statement from Irish Finance Minister Michael Noonan.

The commission sought Ireland to calculate the exact total of the back taxes based on the methodology stated in the ruling. However, Noonan said there is no indication that the amount will overrun or be short of the earlier declared €13 billion for the 10-year period that the calculations are based on. The minister adds that "there are other years to be assessed."

Apple failed to fully pay the taxes it owes to Ireland by its Jan. 3 deadline, CNBC reported Jan. 31, citing the European Union's competition. The tech giant earlier said that it will file an appeal against the commission's order.
