ALWAYS read this skill before touching any Sri Lanka Social Security Contribution Levy (SSCL) work. Use whenever asked about SSCL on turnover for importers, manufacturers, service providers, wholesalers/retailers, or financial-service businesses in Sri Lanka. Trigger on phrases like "Sri Lanka SSCL", "Social Security Contribution Levy", "2.5% turnover levy Sri Lanka", "liable turnover Sri Lanka", or "SSCL registration Sri Lanka". Covers the SSCL at 2.5% on liable turnover, the activity-dependent liable-turnover fraction, and its in-force status (most recently amended by the SSCL Amendment Act No. 24 of 2025). Out of scope — income tax, corporate tax, VAT, and withholding tax (separate skills).

Business activity classification (importer / manufacturer / service provider / wholesaler-retailer / financial services — drives the liable-turnover fraction); gross turnover for the period; SSCL registration status; any exemptions claimed.
R-LK-SSCL-1 — Liable-turnover fraction tables
The exact 25%–100% fraction per activity class is set by the SSCL Act/schedules and changes by amendment — this skill states the principle but does NOT assert the per-activity fraction table. VERIFY against the current SSCL Act and IRD guidance; escalate.R-LK-SSCL-1
R-LK-SSCL-2 — Registration threshold
The quarterly liable-turnover registration threshold is NOT asserted here — VERIFY the current LKR figure with the IRD.

A manufacturer with gross turnover LKR 100,000,000 in a period, where the applicable liable-turnover fraction is (illustratively) 50%:
Liable turnover = 50% × 100,000,000 = 50,000,000
SSCL = 2.5% × 50,000,000 = LKR 1,250,000
The 50% fraction is illustrative only — the real fraction must be taken from the current SSCL schedule for the activity class.
SSCL is administered by the IRD. Return/payment frequency and due dates — VERIFY against the current IRD SSCL guidance (not asserted here).
Known gaps / VERIFY: principal-Act number/year; per-activity liable-turnover fractions; registration threshold; filing frequency and due dates; exemptions.
