Section 2 -- Required inputs and refusal catalogue

Required inputs

• Required inputs before computing PRSI Class S — Before computing any PRSI Class S figure, you MUST obtain: 1. Tax year -- rates change annually and mid-year (1 October) 2. Total income from all sources -- PRSI Class S is levied on aggregate income, not just self-employment 3. Is income from all sources below EUR 5,000? -- if yes, no PRSI liability 4. Does the client have any PAYE employment? -- may already pay Class A 5. Age -- PRSI is not payable once the client reaches age 66 6. 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

• Prohibitions list — 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 citation — Legislation: Social Welfare Consolidation Act 2005, Part II (Social Welfare Consolidation Act 2005, Part II)

Liability determination table (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 definition and threshold rule — "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.
