What is PRSI?

PRSI — Pay Related Social Insurance — is the social insurance contribution deducted from most workers' pay in Ireland. It is not a tax: it goes into the Social Insurance Fund, and it qualifies you for Jobseeker's Benefit, Illness Benefit, Maternity Benefit and the State Pension. Most private-sector employees pay Class A PRSI, the class this calculator covers. Your employer also pays PRSI on your behalf, at a higher rate, and that never comes out of your pay.

The key fact for 2027: employee PRSI rises from 4.35% to 4.5% on 1 October 2027, under the roadmap legislated in the Social Welfare (Miscellaneous Provisions) Act 2024. Budget 2027 did not change PRSI rates. Because the rise lands in October, a full 2027 year blends nine months at 4.35% with three months at 4.5% — an effective rate of 4.3875%. To see how PRSI fits into your whole payslip, run the same salary through our Free Ireland net salary calculator.

How to use the calculator

1. Enter your gross annual salary — the full yearly figure in your contract, before any deductions.
2. Enter your weekly hours (optional) — this shows your implied hourly rate; it does not change the PRSI result.
3. Read the breakdown — the January–September charge, the October–December charge, any credit, and your employer's share.
4. Share or save the result — the “Copy link to this result” button encodes your inputs in the URL, handy when comparing two job offers.

The formula

Employee PRSI (Class A) in 2027 works in three bands, based on weekly gross pay:

PRSI = weekly gross × blended rate (4.3875%) − tapered credit (if any)

• Weekly gross of €352 or less: no employee PRSI at all. Your annual salary is below about €18,304, so the calculator returns €0.
• Weekly gross of €352.01–€424: full-rate PRSI minus a tapered credit — €12 a week at €352.01, falling to €0 at €424. This calculator uses the linear taper: credit per week = €12 × (€424 − weekly gross) ÷ €72, spread evenly across the year.
• Weekly gross above €424: full rate, no credit — 4.3875% of your whole gross salary for 2027 (9 months at 4.35%, 3 months at 4.5%).
• Employer PRSI (Class A): your employer pays 9.15% rising to 9.30% on weekly earnings of €600 or less in 2027, and 11.40% rising to 11.55% above €600 a week. The €600 threshold rose from €552 in Budget 2027. This is your employer's cost, not a deduction from your pay.
• Excluded on purpose: income tax (PAYE), USC, pension contributions and benefits-in-kind — this calculator isolates PRSI only.

Worked example

Take an expat on €50,000 a year — €961.54 a week, above the €424 credit band, so the full rate applies. January to September: €50,000 × 4.35% × 9/12 = €1,631.25. October to December: €50,000 × 4.5% × 3/12 = €562.50. Result: €2,193.75 of PRSI for 2027 — €42.19 a week, €182.81 a month. Your employer pays another €5,718.75 on top (11.4375% blended). Two more cases show the bands at work: on the 2027 full-time minimum wage — €14.94 an hour × 39 hours × 52 weeks = €30,300.48 a year — PRSI is €1,329.43 a year (€25.57 a week). On €20,000 a year (€384.62 a week, inside the credit band), PRSI before credit is €877.50, the tapered credit is about €341.33, so net PRSI is about €536.17 a year — approximate, because the statutory credit is calculated week by week. And on €18,000 a year (€346.15 a week, below €352), PRSI is €0. If you earn the minimum wage, check the full picture in our Free Ireland net salary calculator.

PRSI at a glance: 2027 estimates

*The €20,000 row is approximate: the tapered credit is calculated week by week on actual weekly pay. Once you pass €424 a week, PRSI is a straight percentage of everything you earn — there is no upper limit, unlike income tax bands.

What your employer pays: employer PRSI in 2027

Your employer's PRSI never comes out of your pay, but it matters when you negotiate, because it is part of what you cost to hire. In 2027 the lower employer rate is 9.15%, rising to 9.30% from 1 October, on weekly earnings of €600 or less. Above €600 a week the standard rate applies: 11.40% rising to 11.55%. Budget 2027 raised the lower-rate threshold from €552 to €600, which keeps a full-time minimum-wage worker — €582.66 a week at €14.94 an hour for 39 hours — on the lower rate. On that €30,300.48 salary your employer pays about €2,783.86 a year; on a €50,000 salary, about €5,718.75. The threshold is a cliff, not a band: one cent over €600 a week and the whole week's pay is charged at the higher rate. If you are weighing a job offer, our Free Ireland net salary calculator shows what you keep, while this page shows what the job costs on both sides.

What does PRSI pay for?

PRSI is not a tax that vanishes into general spending — it funds the Social Insurance Fund, which pays the benefits your contributions qualify you for. The main ones are Jobseeker's Benefit if you lose your job, Illness Benefit if you cannot work because of sickness, Maternity Benefit, and the State Pension (Contributory) when you retire. How much you can claim depends on how many PRSI contributions you have built up — Class A contributions give the widest cover, which is why most employees are in Class A. New arrivals should know that PRSI also affects the State Pension: you generally need a minimum number of paid contributions to qualify, so starting contributions early pays off decades later.
