How PAYE Tax Works
in Ireland (2026)

When you receive a payslip in Ireland as a PAYE employee, three separate deductions reduce your gross salary to your net take-home pay: Income Tax (PAYE), the Universal Social Charge (USC), and Pay Related Social Insurance (PRSI). Each is calculated independently, on its own base, with its own rates, thresholds and exemptions, and none of the three refers to the other two. A single person on €55,000 in 2026, for example, keeps €3,524 a month after all three, an effective rate of 23.12% (the rate charged on their very next euro earned is higher, at 47.24%: see our piece on effective versus marginal tax for why the two numbers differ).

Understanding how each deduction is calculated lets you check a payslip, plan for a salary change, or judge whether a pension contribution is worth it. This guide walks through PAYE, USC and PRSI in turn, then the order payroll applies them in, credit versus relief, and a worked example.

Pay As You Earn (PAYE) is Ireland's income tax system for employees. It is charged on your taxable income in two bands: a standard rate of 20% on income up to your standard rate cut-off point, and a higher rate of 40% on anything above it. The cut-off point is not a tax-free allowance: it is simply the threshold where the rate on your next euro changes from 20% to 40%. Every euro up to it is still taxed, just at the lower rate.

Standard rate cut-off points for 2026:

The married two-income figure isn't automatic: the extra €35,000 is transferred from a second earner's own unused band, so how much applies depends on that second income. Full detail in our single versus married take-home pay guide.

Tax credits subtract directly from that calculated tax, after both rates have already done their work (more on how that differs from a relief below). Every PAYE employee automatically gets a Personal Tax Credit (€2,000 single) and an Employee (PAYE) Credit (€2,000), a combined €4,000 that is why the first approximately €20,000 of a single employee's income is effectively tax-free in 2026: €4,000 of credit exactly cancels the 20% tax on the first €20,000. Many further credits exist for married status, caring for a child at home, a dependent relative, renting privately, age, blindness and more. See our guide to Irish tax credits for the full list and what each is worth.

The Universal Social Charge is charged on your gross income in a series of bands. It was introduced in 2011 to replace the Health Levy and Income Levy, and remains one of the key components of Irish personal taxation.

USC bands for 2026:

If your total income for the year is €13,000 or less, you are fully exempt from USC. Once your income exceeds €13,000, USC applies to all of your income from the first euro, not just the portion above €13,000.

Two groups pay a reduced maximum USC rate of 2%: those aged 70 or over with income of €60,000 or less, and holders of a full medical card with income of €60,000 or less. Once income exceeds €60,000, both groups revert to the standard USC rates, including the 8% top rate.

USC is charged on a genuinely different base to PAYE, not just a different rate table. PAYE is worked out on your taxable income, gross pay minus any allowable pension contribution and other reliefs. USC is charged on your gross pay before those deductions. A pension contribution that shrinks your PAYE bill has no effect on USC at all, which is never shown the reduced figure, and beyond the two reduced-rate cases above it has no credits or allowances either.

PRSI is a weekly contribution that funds state social insurance benefits including the Contributory State Pension, Jobseeker's Benefit, Maternity Benefit, Paternity Benefit, and Illness Benefit. Most employees pay Class A PRSI.

The employee PRSI rate for 2026 is 4.20% on gross weekly earnings from January through to September. From 1 October 2026, the rate rises to 4.35%, part of the multi-year PRSI Roadmap agreed by Government.

Employees earning less than €352 per week (approximately €18,304 per year) are exempt from PRSI. Employees aged 70 or over are also exempt, moving to the PRSI exemption Class J.

For employees earning between €352.01 and €424 per week, a PRSI credit reduces the PRSI due. The maximum credit is €12 per week (for those just above the threshold), tapering to zero at €424 per week. This prevents a sharp cliff-edge for lower-paid workers just above the exemption limit: without it, earning one euro over the threshold would suddenly cost far more than the euro itself.

PRSI is charged on the same gross pay as USC, before pension deductions. But it's unlike both other deductions in how it treats time: PAYE and USC are cumulative across the tax year, which is why an emergency-tax overpayment corrects itself on a later payslip. PRSI has no such memory: each pay period is assessed entirely on its own, against that period's own threshold. See our guide to the cumulative basis and pay frequency for what that means for a real payslip.

Employer PRSI is a separate contribution, calculated on the same gross pay at the employer's own rate, and paid on top of your salary rather than deducted from it, which is exactly why it never appears as a line on your payslip. For a single person on €55,000, it adds a further €6,208 a year, bringing the true cost of employing that person to €61,208, over 11% more than the salary itself:

Payroll software doesn't apply one blended "tax rate": it runs three separate calculations in a fixed order, then subtracts every result from your gross pay. For a single person on €55,000 in 2026, aged 35, with no pension contribution and standard credits, that sequence looks like this:

1. Work out taxable pay for PAYE: gross pay minus any allowable pension contribution. No pension here, so it's the full €55,000.
2. Split at the cut-off, apply both rates: €44,000 at 20% (€8,800), the remaining €11,000 at 40% (€4,400), before credits.
3. Subtract tax credits: €4,000 comes straight off, leaving €9,200 PAYE due.
4. Calculate USC separately, on gross pay, not taxable pay: USC never sees the pension deduction from step 1, giving €1,183 for the year.
5. Calculate PRSI separately again, assessed week by week: €2,331 at the 2026 blended employee rate.
6. Add the three, subtract from gross: €12,713.44 in total deductions, leaving €42,287 take-home for the year, or €3,524 a month.

The order matters: because step 1 happens before steps 4 and 5, anything that reduces PAYE's base has no effect at all on USC or PRSI. Only PAYE ever sees a reduced figure.

Both a tax credit and a tax relief reduce what you pay, but they act at different points in the sequence above, and that difference changes how much each one is actually worth to you.

A credit, like the Personal Credit or the Employee (PAYE) Credit, is subtracted directly from the tax bill in step 3, after both the 20% and 40% bands have already been applied. Its value is fixed: a €2,000 credit is worth exactly €2,000 off your tax, whether you're a standard-rate or a higher-rate taxpayer.

A relief, most commonly a pension contribution, works earlier, in step 1: it's subtracted from your gross pay before the bands are even applied, reducing the income taxed at 20% or 40% rather than the tax itself. So its value isn't fixed: a euro of relief is worth more to a higher-rate taxpayer, since it comes off income that would otherwise have been taxed at the higher rate. The age-related limits and earnings cap that govern how much contribution qualifies, with a calculator for your own, are on our pension tax relief page. Either way, a relief only ever touches PAYE: as steps 4 and 5 show, neither it nor a credit has any effect on USC or PRSI.

Treating "my tax rate" as one flat percentage. There isn't one: PAYE is progressive with credits, USC is progressive with no credits, and PRSI is a flat rate above a threshold with a short taper. Three different shapes of curve, added together, land on the payslip.

Assuming a bigger pension contribution shrinks every deduction. It only shrinks PAYE. USC and PRSI are both charged on gross pay before the pension is deducted, so a payslip with a large contribution can still show USC and PRSI lines barely different from one with none, even though PAYE has dropped considerably.

Assuming the standard cut-off point on this page is your own. A real Tax Credit Certificate can show a different cut-off and credits: a transferred band, flat-rate expenses, or another Revenue adjustment. Our calculators let you enter those figures instead of the standard ones.

Treating PRSI as a smooth annual percentage. It's assessed week by week against a hard threshold. Someone whose weekly pay dips just under €352, through unpaid leave or reduced hours, pays no PRSI for that single week, even if their annual salary looks comfortably above the exemption on paper.

Forgetting employer PRSI is a real cost, just an invisible one. It's easy to think a salary costs an employer exactly what it costs you in gross pay. It doesn't: as the worked example shows, it costs over a tenth more again.

Rates, bands, thresholds and credits: Revenue's PAYE, USC and PRSI guidance, and the Department of Social Protection's PRSI classes and rates, verified against the 2026 Budget. Every euro figure on this page is calculated by the IrishPAYE engine at those 2026 rates for a single employee aged 35 on standard credits with no pension contribution, the same engine behind every figure on this site. Your own age, filing status, credits or a pension contribution will change the numbers, which is what the calculator is for.
