Three charges, three sets of rules
Irish pay is reduced by three separate charges, and the reason take-home pay is hard to guess here is that none of them share a threshold. Income Tax is 20% up to your standard rate cut-off point — €44,000 for a single person in 2026 — and 40% above it. USC (Universal Social Charge) runs on its own ladder: 0.5% on the first €12,012, 2% on the next €16,688, 3% on the next €41,344 and 8% on the balance. PRSI is a flat 4.2% once you earn more than €352 a week. Three charges, three completely different band structures, all applying to the same salary.
Income Tax also works back-to-front compared with most countries. There is no tax-free allowance deducted before the bands. Instead the tax is calculated on every euro, and then your tax credits — €4,000 for a single employee, €6,000 for a married couple with one income — are subtracted from the bill. The effect is similar at the bottom but the mechanism matters, because credits reduce tax owed euro for euro rather than sheltering a slice of income.
On €50,000 as a single employee that works out to €7,200 income tax, €1,033 USC and €2,100 PRSI, leaving €39,667. Every line is reproducible in the take-home pay calculator.
The €13,000 cliff
This is the one that genuinely costs people money, and it is not a rounding quirk — it is how the rule is written. USC has an exemption limit of €13,000. Revenue states it plainly: if your income is greater than the exemption limit, you pay USC on your full income. Not on the excess — on all of it, back to the first euro.
So the numbers look like this:
| Gross income | USC | Take-home |
|---|---|---|
| €13,000 | €0.00 | €13,000.00 |
| €13,001 | €79.84 | €12,921.16 |
Earning one euro more leaves you €78.84 worse off, and you do not get back to where you were until your gross income reaches roughly €13,082. For anyone working part-time, on a student contract, or picking up occasional extra shifts near that level, the band between €13,000 and €13,082 is one where working more genuinely pays less. It is worth knowing about before you agree to the extra hours, not after.
The band where €20,000 is taxed harder than €30,000
PRSI has a second oddity. Below €352 a week you pay nothing. Above it you pay 4.2% on everything, not just the excess — softened by a PRSI Credit of up to €12 a week, which is reduced by one-sixth of every euro earned above €352.01 and disappears entirely at €424 a week. Withdrawing that credit is itself a tax, and it lands on top of income tax and USC.
The result is a stretch of income — roughly €18,300 to €22,000 a year — where the marginal burden reaches about 42.9%. Someone earning €30,000 faces roughly 27.2% on their next euro. A worker on €20,000 therefore keeps less of a pay rise than a colleague earning half again as much, which is the reverse of how a progressive system is supposed to feel.
What the calculator covers — and what it doesn't
- Class A employee PRSI. Self-employed (Class S), public servants on modified classes and proprietary directors follow different rules.
- Standard credits only — the personal and employee credits. Rent Tax Credit, Home Carer, Single Person Child Carer, medical expense relief and tuition relief are not applied and can change the outcome materially.
- Pension contributions are not deducted, and they are unusually valuable in Ireland because relief is given at your marginal rate.
- The married figure assumes one income. Two-income couples have a different combined cut-off point.
- A mid-year PRSI change is scheduled. The rate is set to rise again in October 2026; we apply the rate in force and note changes rather than applying them early.
