Formula & Methodology Behind the Calculator
The calculator uses the official 2018 Irish tax rules to determine your net bonus. Here’s how it works:
1. PAYE Income Tax Calculation
For 2018, Ireland had the following income tax bands:
| Tax Band | Single Person | Married/Civil Partner (One Income) | Married/Civil Partner (Two Incomes) |
|---|---|---|---|
| Standard Rate (20%) | Up to €34,550 | Up to €43,550 | Up to €43,550 (increased by €26,300) |
| Higher Rate (40%) | Balance | Balance | Balance |
2. Universal Social Charge (USC) Rates for 2018
| Income Range | USC Rate |
|---|---|
| First €12,012 | 0.5% |

| Over €100,000 | 8% (no upper limit) |
3. PRSI Contributions
For 2018, PRSI was calculated at 4% for most employees (Class A). The calculator applies this rate to your bonus amount.

Expert Tips for Managing Bonus Taxation
Before Receiving Your Bonus
- Check your tax credits: Ensure your PAYE tax credits are up to date with Revenue. You can claim additional credits if eligible (e.g., for medical expenses or tuition fees).
- Consider pension contributions: Increasing your pension contributions before receiving a bonus can reduce your taxable income. For 2018, contributions were tax-deductible up to certain limits.
- Review your payslips: Understand how your regular income is being taxed to anticipate how your bonus will be treated.
After Receiving Your Bonus
- Verify the calculation: Use this calculator to double-check that your employer has deducted the correct amount of tax.
- Plan for tax refunds: If you’ve overpaid tax during the year, you may be due a refund. The bonus might push you into a higher tax band temporarily, but you can claim back overpaid tax at year-end.
- Consider tax-efficient investments: Use your net bonus for investments that offer tax advantages, such as Approved Retirement Funds (ARFs) or Tax-Free Savings Accounts.
- Consult a tax advisor: For complex situations (e.g., if you have multiple income sources or are self-employed), professional advice can help optimize your tax position.
Interactive FAQ
Why is my bonus taxed higher than my regular salary?
Bonuses in Ireland are typically taxed at your highest rate of income tax (40% for most earners) because they are considered “additional income.” Unlike your regular salary which is spread across tax bands, bonuses are often taxed as if they were all earned in the highest band. This is why you might see a higher effective tax rate on bonuses compared to your regular pay.
Can I reduce the tax on my bonus?
Yes, there are several strategies to reduce the tax burden on your bonus:
- Pension contributions: Increasing your pension contributions before receiving the bonus can reduce your taxable income.
- Tax credits: Ensure you’re claiming all eligible tax credits, such as medical expenses or tuition fees.
- Salary sacrifice: Some employers allow you to sacrifice part of your bonus for benefits like additional pension contributions or health insurance, which may be tax-efficient.
For 2018, the pension contribution limits were generous, allowing significant reductions in taxable income.
How does USC differ from PAYE on bonuses?
PAYE (Income Tax) and USC (Universal Social Charge) are separate taxes with different rates and bands:
- PAYE: Progressive tax with rates of 20% and 40% (for 2018). Bonuses are typically taxed at 40% if they push your income into the higher band.
- USC: A separate charge with multiple bands (0.5% to 8% in 2018). USC is calculated on your total income, including bonuses, but the rates are generally lower than the higher PAYE rate.
The calculator combines both to give you the total deduction.
What is PRSI and how is it calculated on bonuses?
PRSI (Pay Related Social Insurance) is a social security contribution that funds benefits like the State Pension and unemployment payments. For most employees (Class A), PRSI was calculated at 4% of gross income in 2018, including bonuses. There was no upper limit for PRSI on bonuses, so the full 4% applies regardless of your income level.
My bonus was taxed at 52%—is this correct?
Yes, it’s possible for your bonus to be taxed at an effective rate of 52% or higher. This happens because:
- PAYE at 40%
- USC at up to 8%
- PRSI at 4%
When combined (40% + 8% + 4%), the total deduction can reach 52%. This is why bonuses often feel “heavily taxed” compared to regular salary.
How do I claim back overpaid tax on my bonus?
If you believe you’ve overpaid tax on your bonus, you can claim a refund through Revenue’s myAccount service. Here’s how:
- Log in to myAccount on the Revenue website.
- Go to “Review Your Tax” and select the 2018 tax year.
- Check your tax credits and ensure all deductions (e.g., pension contributions) are accounted for.
- Submit a claim for any overpaid tax. Revenue will process this and issue a refund if applicable.
You typically have 4 years from the end of the tax year to claim a refund, so for 2018, you had until December 31, 2022.
Does this calculator account for the “bonus tax trap”?
Yes, this calculator accounts for what’s commonly called the “bonus tax trap.” This occurs when your bonus pushes your total income into a higher tax band, but your regular salary is taxed at the lower rate. The calculator simulates how Revenue treats the bonus as “additional income” and applies the appropriate marginal tax rates (40% PAYE + USC + PRSI) to the entire bonus amount, which is how it’s typically taxed in practice.
