Bonus Tax Ireland 2026: How PAYE, USC & PRSI Eat Into Your Bonus
Getting a bonus is great — until you see how much disappears to tax. In Ireland, bonuses are taxed as regular employment income, meaning PAYE (up to 40%), USC (up to 8%), and PRSI (4.2%)all apply. The effective rate can reach 52% for high earners. Use our Free Bonus Tax Calculator to see exactly what you'll take home.
The Three Taxes on Your Bonus
Unlike some countries that have a separate bonus tax rate, Ireland treats your bonus as additional employment income. This means it's added to your regular salary and taxed at your marginal rate for each of the three deductions.

Bonus Sacrifice: The Most Tax-Efficient Option
Instead of taking your bonus as cash, you can sacrifice it directly into your pension. This is the single most tax-efficient thing you can do with a bonus in Ireland.

Full amount invested, tax-free growth
By sacrificing your bonus to pension, you avoid all three taxes — PAYE, USC, and PRSI. The full €10,000 goes into your pension fund, where it grows tax-free. You'll pay Income Tax when you withdraw in retirement, but at your marginal rate which is typically lower than during your working years.
Does Bonus Timing Matter?
Yes — the timing of your bonus can affect how much tax you pay, particularly for USC.
December vs January Bonus
A December bonus is taxed in the current tax year; a January bonus falls into the next year. If you expect a higher income next year (pay rise, second job), taking the bonus in December could mean lower overall USC. If your income will be lower next year, January may be better.
The 8% USC Cliff
If your salary is just below €70,044 and your bonus pushes you over, every euro of bonus above that threshold faces 8% USC instead of 3%. This creates a USC marginal rate spike that can make a December bonus significantly more expensive than expected.
Pension Contribution Timing
If you plan to sacrifice your bonus to pension, the timing matters for your age-related relief limit. Making the contribution in the same tax year as the bonus ensures the relief applies correctly.
