Ireland’s wealthiest taxpayers are subject to an effective income tax rate of 33%, almost twice the rate applied to all other income earners, a new report from the Comptroller and Auditor General has revealed. The analysis covers 1,558 high-net-worth individuals who are collectively expected to pay €421 million in income tax.
The findings highlight the significant contribution made by a relatively small cohort of earners to the State’s overall income tax revenue. The report provides fresh insight into the progressive nature of Ireland’s tax system, showing that those at the top of the earnings scale bear a substantially higher burden than the broader taxpayer base.
Key facts
- 1,558 wealthy individuals are liable to pay €421 million in income tax
- Effective tax rate for high earners stands at 33%
- This rate is approximately double that paid by other income taxpayers
- Data compiled by the Comptroller and Auditor General
Comparative tax burden analysis
The 33% effective rate paid by wealthy individuals contrasts sharply with the lower rates experienced by the majority of Irish workers. While nominal tax rates in Ireland can reach 40% for the highest earners under the standard income tax regime, the effective rate takes into account all allowances, credits, and reliefs that reduce the actual tax paid as a proportion of total income.
The Comptroller and Auditor General, the independent officer responsible for auditing public expenditure and revenue, compiled the figures as part of ongoing scrutiny of the tax system’s performance and equity. The report underscores the concentrated nature of high-value tax collection, with just over 1,500 individuals contributing more than €400 million to the Exchequer.
Revenue concentration and policy implications
The data points to a significant concentration of tax revenue among a small number of high-income earners. This group’s average tax contribution exceeds €270,000 per person annually, representing a substantial individual liability compared to the average Irish taxpayer.
For policymakers and the Department of Finance, these figures illustrate both the effectiveness of progressive taxation and potential vulnerabilities in revenue collection. A heavy reliance on a small number of wealthy taxpayers could create volatility in public finances if economic conditions change or if high earners relocate.
The report arrives as Ireland continues to benefit from strong corporate and income tax receipts, though concerns persist about the sustainability of certain revenue streams, particularly corporation tax from multinational companies. Understanding the contribution patterns of different taxpayer cohorts remains essential for long-term fiscal planning and ensuring equity in the tax system.
The Comptroller and Auditor General’s analysis provides transparency around who pays what in the Irish tax system, informing ongoing debates about tax fairness, progressivity, and the balance between economic competitiveness and adequate public revenue generation.
