The Irish State will miss its full-year corporation tax projections despite collecting a record €22.7bn by the end of September. While exchequer returns show business tax receipts are up following a headline rate increase to 15 percent, the Department of Finance revised its yearly forecast down from €35.3 billion to €34 billion.
Exchequer Returns Show €22.7bn in Business Taxes
Gross revenue in the Government’s central fund reached €96.1bn by the end of September, marking a 5.4 percent or €4.9bn increase compared to the previous year. Total spending for the same period hit €93.7bn, leaving the budget with a €2.4bn surplus. In September alone, the State collected €4.9bn in company taxes, which is €3.1bn higher than the same month last year. Department of Finance officials attributed this jump to a small number of large multinationals paying their annual tax bills earlier than usual.
Tánaiste and Finance Minister Simon Harris stated that the returns showed significant distortions caused by the timing of corporation tax payments while maintaining a positive trend. Deloitte Ireland tax and legal partner Daryl Hanberry noted that it remained unclear how much of the corporate tax take stemmed from the new 15 percent rate paid for the first time this year, up from the previous 12.5 percent.
Despite the pre-budget cash surge, the Government admitted that overall corporation tax collections for the year will fall short of expectations. The Department of Finance initially anticipated receipts of €35.3bn in April. Reports last month suggested that figure would be exceeded by a wide margin before being revised down to €34bn. A department spokesman explained that certain payments expected this year will not arrive until early next year.
Reliance on a small cohort of companies underpins the fiscal exposure. Close to half of all business tax income comes from just three firms: Eli Lilly, Apple, and Microsoft. Pfizer previously accounted for a major share of receipts during the Covid-19 pandemic before experiencing subsequent business shifts that altered its tax contributions.

Tax revenues rise as government sets budget package
Total tax revenues for the year reached €78.9bn by the end of September, up 8.1 percent on the previous year. Income tax receipts rose 7.8 percent to €27.8bn, remaining the Government’s largest revenue stream. Harris emphasized that the resilient economy provides the capacity to deliver a budget that invests in public services and infrastructure while saving for the future. The Government set out an overall package of new measures worth €8.5bn, including €1.5bn in tax cuts.
Jack Chambers stated that Budget 2027 will continue infrastructure and public service investment while focusing on reform, efficiency, and driving value for money. Budgetary watchdogs and the Economic and Social Research Institute have previously warned against using exceptional tax income to fund recurring day-to-day spending.
