PRSI Explained: Class A Contributions
5 min read
PRSI is often lumped in with "tax" on a payslip, but it works differently: it's a social insurance contribution that builds your entitlement to future benefits, not a general tax.
Class A: the standard employee rate
Most private-sector employees pay Class A PRSI at 4.2% of gross earnings for most of 2026, rising to 4.3% from 1 October 2026 as part of a phased increase to fund the Social Insurance Fund. If you earn €352 or less per week, you pay no PRSI at all for that week.
Why your PRSI record matters
- The State Pension (Contributory) requires a minimum number of paid contributions — currently 520 (10 years) for any pension, with 40 years for the maximum rate.
- Jobseeker's Benefit, Illness Benefit and other short-term supports also require a minimum recent contribution history.
- Gaps in your PRSI record (e.g. time abroad, unpaid leave) can reduce your eventual pension unless covered by credits or voluntary contributions.
- You can check your own contribution record via Revenue's myAccount or the Department of Social Protection.
Self-employed PRSI (Class S)
Self-employed individuals pay Class S PRSI at 4% on income above €5,000 a year, with a minimum annual payment of €650 where liable. Class S contributions cover a narrower range of benefits than Class A.
Worked example
PRSI on a €50,000 salary (Class A)
€50,000 × 4.2% ≈ €2,100 for the January–September period rate
The exact annual figure blends the pre- and post-October rates — our calculator uses the January–September rate as a simplified annual estimate and flags the October change.

Frequently asked questions
What does PRSI actually pay for?+
PRSI (Pay Related Social Insurance) funds Ireland's Social Insurance Fund, which pays for the State Pension (Contributory), Jobseeker's Benefit, Illness Benefit, Maternity and Paternity Benefit, and other social welfare payments — contingent on your contribution record.
Is everyone on the same PRSI class?+
No. Most private-sector employees are Class A. Public servants recruited before 1995, some self-employed people, and other categories fall under different classes (B, C, D, S, etc.) with different rates and benefit entitlements.
