Section 2 -- Required inputs and refusal catalogue
Required inputs
Before computing any PRSI Class S figure, you MUST obtain:
- Tax year -- rates change annually and mid-year (1 October)
- Total income from all sources -- PRSI Class S is levied on aggregate income, not just self-employment
- Is income from all sources below EUR 5,000? -- if yes, no PRSI liability
- Does the client have any PAYE employment? -- may already pay Class A
- Age -- PRSI is not payable once the client reaches age 66
- Is the client a proprietary director? -- 15%+ shareholding pays Class S
If tax year is unknown, STOP. Do not compute PRSI.
Refusal catalogue
R-IE-PRSI-1 -- EU/EEA cross-border worker. Trigger: client is self-employed in Ireland but resident in another EU/EEA state. Message: "EU Regulation 883/2004 governs which state collects social insurance. Escalate -- do not advise without specialist cross-border guidance."
Prohibitions
- NEVER compute PRSI without confirming the tax year -- rates change annually and mid-year
- NEVER tell a client they owe no PRSI without checking the EUR 5,000 threshold from ALL sources
- NEVER apply a single rate (4.1% or 4.2%) to an annual return -- use the blended rate
- NEVER treat a proprietary director as Class A -- they are Class S regardless of salary arrangements
- NEVER state that PRSI is deductible for income tax -- it is NOT
- NEVER pro-rate the EUR 5,000 threshold for partial years -- it is an annual threshold
- NEVER conflate USC and PRSI -- they are separate charges
Section 3 -- Liability determination
Legislation: Social Welfare Consolidation Act 2005, Part II
| Condition | PRSI liability |
|---|---|
| Total income from all sources >= EUR 5,000 | Class S applies |
| Total income from all sources < EUR 5,000 | No PRSI liability |
| Client aged 66 or over | No PRSI liability |
| Client already paying Class A as PAYE employee | See dual status rules |
"Total income from all sources" includes self-employment income, rental income, investment income, and any other assessable income. The EUR 5,000 threshold is all-or-nothing: if income is EUR 5,001, PRSI applies to the FULL EUR 5,001.
Section 4 -- Rates, formula, and dual status
Rate schedule
| Period | Rate |
|---|---|
| 1 Jan 2025 -- 30 Sep 2025 | 4.1% |
| 1 Oct 2025 -- 31 Dec 2025 | 4.2% |
| 1 Jan 2026 -- 30 Sep 2026 | 4.2% |
| 1 Oct 2026 -- 31 Dec 2026 | 4.35% |
Formula
PRSI = max(total_income x blended_rate, minimum_contribution)
Dual status -- PAYE employment + self-employment
| Scenario | PRSI treatment |
|---|---|
| PAYE (Class A) + self-employment >= EUR 5,000 | Class A on employment + Class S on non-PAYE income |
| PAYE (Class A) + self-employment < EUR 5,000 | Class A only |
| Proprietary director (15%+ shareholding) | Class S on all income |
Class A and Class S can both apply simultaneously to the same individual on different income streams.
Section 5 -- Key rules and coverage
Legislation: Social Welfare Consolidation Act 2005
- PRSI Class S is based on CURRENT year income via self-assessment
- No upper earnings limit -- applies to ALL income above threshold with no cap
- Minimum contribution of EUR 650 applies whenever income >= EUR 5,000 but calculated PRSI < EUR 650
- PRSI is NOT deductible for income tax purposes
- Class S covers: pension, widow/widower's pension, guardian's payment, maternity/paternity/parent's benefit, treatment benefit (from 2025)
Section 6 -- Payment schedule and registration
Payment schedule
| Event | Deadline |
|---|---|
| Preliminary tax (including PRSI) | 31 October (mid-November for ROS e-filers) |
| Final return and balance | 31 October following year (mid-November for ROS) |
PRSI Class S is collected by Revenue through the self-assessment system (Form 11). It is NOT paid separately to DSP.
Voluntary contributions
Former Class S contributors who have ceased self-employment may pay voluntary contributions at EUR 500/year (flat rate, 2025/2026) to maintain pension entitlement. Must apply within 60 months of last compulsory contribution. Confirm contribution record with DSP before advising.
Registration
Register with Revenue Commissioners (Form TR1 for individuals) within 30 days of commencing self-employment.
Section 7 -- Interaction with USC and income tax
| Question | Answer |
|---|---|
| Is PRSI deductible for income tax? | NO |
| Is PRSI part of USC? | NO -- entirely separate charges |
| Are income tax credits applied against PRSI? | NO |
PRSI, USC, and income tax are three independent charges computed separately on different bases with different rules.
