While the companies are not named in the Ifac research, it is understood that the three highest corporation tax payers are Apple, Microsoft and Eli Lilly. Corporation tax receipts almost doubled between 2021 and 2024, Ifac said, even when receipts from the Apple tax judgement are excluded. "We estimate that together, these two tech companies paid almost €11bn of corporation tax in Ireland in 2024, equivalent to almost 40% of total corporation tax receipts." In addition, the 15% minimum effective tax rate for large corporations will lead to increased corporation tax from 2026 onward, Ifac said, with previous estimates suggesting that this higher tax rate could yield an additional €5bn in corporation tax receipts. “This research highlights how reliant Ireland’s corporation tax has become on just three companies," said Brian Cronin, Economist at Ifac and author of the corporation tax research.
