Is a €5,000 Bonus Worth It? The Ultimate Guide to Bonus Tax (2026)
Getting a bonus is great news, but the tax bill often comes as a nasty shock. In Ireland, bonuses are taxed at your marginal rate, which for most professionals means you lose 52% of your reward immediately. This guide explains why this happens and reveals the #1 strategy to keep 100% of your bonus.
1. The "52% Shock" Explained
Unlike some countries where bonuses might have special tax treatment, in Ireland, a bonus is treated exactly like regular salary. It is stacked on top of your existing income.
The Calculation
- Income Tax (PAYE): 40% (if you earn over €44k)
- USC: 8% (on income over €70k)
- PRSI: 4%
- Total Deduction: 52%
This means for a €10,000 bonus, you only take home €4,800. The government takes the majority.
2. The "Bonus Sacrifice" Loophole
There is one completely legal way to avoid this tax: Bonus Sacrifice (AVCs).
Instead of taking the cash, you ask your employer to pay the bonus directly into your pension. Because pension contributions are free from Income Tax (up to age-related limits), you avoid the 40% PAYE entirely.
Cash vs. Pension Example
Take Cash
€4,800
Net in pocket
Put in Pension
€10,000
Invested for you
Note: You may still have to pay USC and PRSI depending on whether it's an occupational scheme or a PRSA, but the savings are still massive.
3. RSU vs. Cash Bonus
Restricted Stock Units (RSUs) are taxed exactly the same as a cash bonus on the day they vest. You cannot "sacrifice" RSUs directly into a pension in the same simple way as a cash bonus. However, you can use a technique called "bed and breakfasting" or simply increase your payroll pension contribution in the month your RSUs vest to offset the tax bill.
