For a single PAYE employee on €80,000 a year at 2026 rates, an extra €1,000 of pay adds about €478 to take-home pay. Every extra euro above €70,044 pays 40% income tax, 8% USC and PRSI, so a little over half of it goes in tax.
Worked example: €1,000 on top of €80,000
- Income tax at 40% (single people pay 20% on the first €44,000 and 40% on the rest): €400.00
- USC at 8% (the rate above €70,044; it is 3% between €28,700 and €70,044): €80.00
- PRSI: €42.38. Employee PRSI is 4.35% from 1 October 2026 (it was 4.2% before), so this is the average over 2026. At 4.35% alone it is €43.50.
- You keep €477.62, a marginal rate of 52.24%.
Your tax credits don't change with a pay rise, so none of them offset the extra tax.

Why Budget gains look small for higher earners
Budgets usually raise tax credits or widen the bands by a fixed amount. A €100 bigger credit is worth €100 a year whether you earn €40,000 or €140,000, and a wider band saves at most the difference between the two rates on the extra amount. On a higher salary that fixed amount is a small share of your pay, and any pay rise on top is taxed at over 50%, so the change on your payslip can look like only a few euro a week.
