The Apple Irish tax ruling means the tech company must start handing over the billions the European Commission deemed it owes Ireland.
The Irish government will start collecting the €13 billion ($15.4 billion) owed to them by tech giant Apple.
In August 2016 the European Commission ruled that Apple must reimburse Ireland €13 billion of what it considered unpaid taxes.
It claimed Apple had paid substantially less tax in Ireland than other businesses.
Ireland has been criticized by Brussels for not collecting the back taxes.
Dublin fears that if it does it may appear less attractive to multinational companies.
Ireland and Apple are appealing the European Commission’s ruling.
Ireland, however, is legally bound by the ruling, although the €13 billion will be held in a temporary escrow account until the conclusion of the appeals process.
Speaking in Brussels, Finance Minister Paschal Donohoe, said: “We have now reached agreement with Apple in relation to the principles and operation of the escrow fund.
“We expect the money will begin to be transmitted into the account from Apple across the first quarter of next year.”
The Irish Times has reported that Poland has sided against Ireland in the court appeal against the ruling that Apple owe €13 billion in taxes.

The paper reports that this may be an attempt by Poland to "curry favour with the commission.”
Back in October, the European Commission said it was taking Ireland to the European Court of Justice for not recovering the €13 billion.
Taoiseach Leo Varadkar had described the decision as “wholly unnecessary and unwarranted at this time”.
He said: “It is our view that tax is a national competence, it’s a matter for this parliament, not a European matter.”
He added: “The NTMA [National Treasury Management Agency] is managing this process. They have tendered for fund managers to set up an escrow account and someone to manage the money until the European Court of Justice decides who it belongs to.”
