Inland Revenue Authority of Singapore (IRAS) publishes annual service-level open data spanning FY2006 through FY2022. Metrics cover telephone answering, case-specific email replies, correspondence handling, in-person taxpayer service, and refund issuance timeliness. Tax administration researchers and oversight bodies can track how IRAS performance evolved across fiscal years. The CSV consolidates operational KPIs into a longitudinal accountability series. Figures describe service standards attainment rather than revenue collection totals.
