Singapore’s IRAS is phasing in mandatory electronic invoice transmission via InvoiceNow, based on the Peppol network, to streamline GST reporting. This system automates data transfer, eliminating manual input and directly transmitting invoice data to the tax agency. Implementation begins with voluntary adoption in May 2025, progressing to mandatory participation for new GST-registered businesses in November 2025 and all voluntarily registered taxpayers by April 2026. Updated guidance following a consultation clarifies that businesses must transmit data on standard, zero-rated, and exempt supplies and purchases reported in GST returns. Certain transactions, such as deemed supplies, exempt financial services, and import permits, are excluded from this data transmission requirement.
