Quick answer
- Class S generally applies where annual self-employed reckonable income is at least €5,000.
- Below €5,000 annual self-employed income, Revenue states that Class S liability does not arise under the standard rule.
- Where liable, 2026 uses 4.20% to 30 September and 4.35% from 1 October, subject to a €650 annual minimum.
- Class S is usually settled through self-assessment and has no employer contribution.

Who commonly pays Class S PRSI?
- Sole traders and people carrying on a trade, profession or vocation.
- Certain company directors who are treated as self-employed for PRSI.
- Certain people with rental, investment or other reckonable non-employment income.
- Some local-authority members and other groups specified in PRSI rules.
Company ownership or the word “contractor” does not by itself settle employment status. DSP can examine the real working relationship and decide the correct insurability class.
The €5,000 liability threshold and €650 minimum
The €650 minimum applies only after the €5,000 annual liability threshold is met. If the threshold is not met, the standard Class S liability is not triggered.
Three annual examples for 2026
- €4,999 reckonable incomeBelow the standard €5,000 liability threshold: no compulsory Class S under this rule.
- €5,000 reckonable income€5,000 × 4.2375% = €211.875 before the minimum. Where liable, the annual amount is €650.
- €20,000 reckonable income€20,000 × 4.2375% = €847.50, above the €650 minimum.
These examples assume the person is liable for Class S and the ordinary annual self-assessed rules apply. The minimum is not an extra €650 added to the percentage result. It is the minimum total contribution where liability exists.
The DSP Class S rate guidance specifies the 2026 annual self-assessed blended rate of 4.2375%. Check age, pension status and insurability separately before relying on an estimate.
2026 Class S rate timing
Class S rates are 4.20% until 30 September 2026 and 4.35% from 1 October 2026. DSP specifies an annual blended rate of 4.2375% for 2026 income returned through Revenue self-assessment, subject to the €650 minimum where liable. This is the published annual self-assessed rate, not just an assumption that income arose evenly.
Confirm the applicable assessment rules where trading starts or stops, pension status changes or another insurability condition applies. The annual return and official guidance determine the liability.
Reckonable income, rental income and company directors
For a trade, use reckonable income determined under the relevant self-assessment rules, including the applicable deductions and capital allowances. It is not simply turnover, drawings or the amount transferred to a personal bank account.
Revenue also states that PRSI can apply to rental income and legally enforceable maintenance payments. Certain company directors can be Class S, but the result depends on the director’s employment status and company relationship. Use professional advice or DSP Scope Section where the position is unclear.
How Class S is paid through self-assessment
- Prepare the tax-adjusted profit or other reckonable income.
- Calculate Income Tax, USC and Class S PRSI separately.
- Include the liabilities in the annual Income Tax return.
- Pay through the self-assessment pay-and-file process, including preliminary tax where required.
- Check the Contribution Statement later to confirm the social-insurance record.
Unlike employee Class A, there is no employer share. The full cash reserve must be planned by the self-employed person.
Class S benefits and age 66–70
Class S can support State Pension (Contributory), maternity, paternity, parent’s, adoptive, carer’s, treatment and other specified benefits, subject to each scheme’s conditions. It does not provide identical coverage to Class A.
Since 2024, self-employed people who defer State Pension (Contributory) can remain liable until the pension is awarded or age 70. People born before 1 January 1958 or already receiving the pension can have different treatment.
Class S versus voluntary contributions
Class S is a compulsory contribution where the self-employed liability conditions are met. Voluntary contributions are a separate arrangement for certain people who are no longer compulsorily insured and want to help maintain coverage for long-term benefits.
Someone with current compulsory Class S liability cannot simply replace it with a lower voluntary contribution. Eligibility and application deadlines for voluntary contributions should be checked with DSP.
