Apple paid Ireland $17.1 billion in tax last year, around 40% of its worldwide total, according to a company filing setting out its tax liabilities country by country. Its global income tax bill for the fiscal year to September 2025 was $43.2 billion.
Stated that way it sounds like the most extreme example yet of profit shifting into a small European economy. Read one line further and it is mostly something else.
The arithmetic
The $17.1 billion includes the €13 billion, about $15.18 billion, in back taxes the European Union's highest court ordered Apple to pay Ireland in 2024.
Take that out and Apple's ordinary Irish tax for the year was roughly $1.9 billion, or about 4% of its global bill rather than 40%. The headline number is a court judgment landing in a single year, not a description of how Apple is taxed.
That distinction matters in both directions. It means the 40% figure will not repeat next year. It also means the underlying arrangement, the one the European Commission spent eight years litigating, is what the 4% describes, and $1.9 billion of tax on the profits routed through Irish entities is its own kind of answer.
What the case was about
The Commission alleged in 2016 that Ireland had granted Apple tax treatment unavailable to other companies, which under EU law is illegal state aid, and ordered recovery of the difference. Both Apple and the Irish government fought it, Ireland arguing against being handed billions it said it was not owed, which is unusual behaviour for a treasury and tells you what it valued more than the money.
Ireland won at the General Court in 2020 and lost on appeal in 2024, when the Court of Justice set that ruling aside and restored the Commission's decision. The money, held in escrow throughout, went to the Irish exchequer.
Why Ireland in the first place
Ireland's headline corporate rate is 12.5%, well below the US federal rate, and for decades it paired that with a legal environment that let multinationals hold intellectual property in Irish entities and license it to operating companies elsewhere. Profit follows the intellectual property, so profit arrived in Ireland while the customers stayed in France, Germany and Britain.
The structures that made the effective rate far lower than the headline one have largely been closed, and the international regime has moved. Under the OECD's Pillar Two agreement, large multinationals face a minimum effective rate of 15% wherever they book profit, and a jurisdiction taxing below that simply cedes the difference to another government. That removes most of the point of the arrangement, which is why Ireland ultimately supported the reform it had spent years resisting.
The exposure that remains
The concentration of Ireland's corporate tax base in a handful of US multinationals is a real fiscal risk, and Irish officials have said so themselves for years. A tax base this dependent on a few firms' structuring decisions can change faster than a budget can adjust, whether through a US tax change that repatriates profit, a corporate reorganisation, or the ordinary business risk that one of those companies has a bad decade.
The Apple payment illustrates the point rather than resolving it. A windfall of $15 billion is welcome in any exchequer. Building a spending base on the kind of revenue that arrives once, by court order, is the thing Irish finance ministers keep warning against.
