In Ireland, employment income is taxed through three separate charges: income tax (20% and 40%), Universal Social Charge (USC, from 0.5% up to 8%) and PRSI (4.1% for most employees). Together they mean your marginal rate can reach around 52%, and it climbs sharply at a handful of key income milestones.
The three taxes on your income
- Income tax — charged at 20% on your income up to your standard rate band, and 40% on anything above it.
- Universal Social Charge (USC) — a separate tax on your total income, with rates from 0.5% up to 8%.
- PRSI (Pay Related Social Insurance) — 4.1% for most employees, funding social welfare benefits such as the State Pension.
The headline rates
| Tax | Rate(s) | Notes |
|---|---|---|
| Income tax | 20% standard / 40% higher | 20% applies up to your standard rate band |
| USC | 0.5% to 8% | Steps up through bands as income rises |
| PRSI | 4.1% (employee, Class A) | Employers pay an additional amount on top |
5 milestones where your tax rate jumps
- You start paying income tax once your earnings exceed your tax credits and the 20% standard rate band.
- You move onto the 40% higher rate once your income goes above your standard rate band.
- USC steps up through its bands, reaching the top rate of 8% on the highest portion of income.
- PRSI applies to most employees at 4.1% (with different treatment below certain weekly thresholds).
- At the top end, your combined marginal rate is around 52% — 40% income tax plus 8% USC plus 4.1% PRSI.
Why your marginal rate matters
A pay rise or bonus is taxed at your marginal rate, not your average rate. Once you are past the milestones, a large slice of any extra income goes to tax — so it is worth planning how you are paid, and using tax-efficient options such as pension contributions, before you take extra cash out of the business.
Standard rate bands
- Single person: €44,000 at the 20% rate
- Married couple or civil partners, one earner: €53,000 at 20%
- Married couple or civil partners, two earners: up to €88,000 at 20% (€44,000 each)
The standard rate band is usually increased in each Budget, so the figures above are for the current tax year — confirm the latest bands with your accountant.
Frequently asked questions
What is the highest rate of income tax in Ireland?
The higher rate of income tax is 40%. There is also USC (up to 8%) and PRSI (4.1% for employees) on top, which can bring the combined marginal rate to around 52%.
When does the 40% tax rate kick in?
The 40% rate applies to income above your standard rate band, which is updated in each Budget. For a single person it currently stands at €44,000 a year.
Do I pay USC and PRSI as well as income tax?
Yes. USC and PRSI are charged in addition to income tax, so your total deduction is higher than the headline income tax rate alone.
How can I reduce my tax bill?
Pension contributions are one of the most effective ways to reduce tax, because they qualify for income tax relief. Other options include using your tax credits fully and structuring pay efficiently if you are a company director.
