Prefer this over the full payroll suite when the payslip already exists and you only need an audit diff, not a net-pay computation from scratch. It is more targeted than the Japan social insurance premiums endpoint alone because it covers withholding tax and produces actionable match/mismatch verdicts rather than just computed values.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-02T03:59:07.073Z","isFirstParty":false,"canonicalSlug":"mart402-japan-payslip-audit-833efdac"}
