The Inland Revenue Authority of Singapore (IRAS) has announced the implementation of a phased adoption of InvoiceNow, the national e-invoicing framework based on the Peppol network, for GST registered businesses starting in May 2025. The mandate will cover B2B transactions only, as the Government expects to make B2G mandatory in the following years.

The mandate will require GST registered businesses to use InvoiceNow solutions to transmit invoice data to IRAS. The transmission of invoice data to IRAS will be done through Peppol Access Point service providers, extending the traditional four corner e-delivery model to a fifth corner model.

The mandate will be implemented in phases, as follows:

  • From 1 May 2025, for voluntary early adoption by GST-registered businesses, as a soft launch.
  • From 1 November 2025, for newly incorporated companies that register for GST voluntarily.
  • From 1 April 2026, for all new voluntary GST-registrants.

Even though, a implementation timeline for all businesses has not been shared yet, further updates are expected in the future.
