Apple is said to owe 13 billion euros (estimated $16 billion USD) to Ireland, according to the country’s tax collectors, Reuters reports.

Niall Cody, Revenue Commissioners’ chairman, says that Apple’s bill (which it is disputing) is “ in that ballpark,” and that nearly all calculations will be done and sent before the end of April.

As we reported back in January, Ireland was ordered to recover 13 billion euros from Apple in underpaid taxes, and it looks like this will indeed be the final amount that will be owed. Payments will be made starting in March, going through September.

Over 95 percent of the calculations are completed and we have agreed with the Commission that all our calculations will be with them before the end of April.

It will be quite some time before any appeals will be heard, however, which means we won’t see the end of this story for quite a while.
