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.
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 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.
