Ireland has given “no indication” about when it will begin to collect €13bn in back tax from Apple, according to European Competition Commissioner Margrethe Vestager.

Last month, Vestager had warned the Commission would take court-enforcement action against Ireland over failure to collect the tax money, which is under appeal by both Ireland and Apple.

As reported by the Irish Independent online, Irish officials insist they are still working to comply with the Commission ruling, which will involve calculating the exact amount to be owed before setting up an escrow account.

Vestager, however, said she is still unclear about the timeframe by which Dublin will collect the €13bn.

“We have no indication when it comes to the time perspective in recovering the unpaid taxes from Apple,” she told the Irish Independent at the Web Summit in Lisbon.

“We do have from the Irish government the progress made when it comes to figuring out how to deal with such amounts of recovered taxes. I respect the complexities of how to keep €13bn while the court case takes place.

“But we need to see progress when it comes to making the recovery because we have seen that the Belgians have done it, the Dutch have done it and Luxembourg has done it in terms of recovery,” she added. “Because of equal treatment, we expect the Irish to do it.”

According to Irish Independent, Vestager also said the “Paradise Papers” might prompt another probe of Apple.
