What is the InvoiceNow GST requirement?

InvoiceNow is Singapore's nationwide e-invoicing network built on Peppol. IRAS is phasing in a requirement for GST-registered businesses to transmit invoice data to IRAS via InvoiceNow: early voluntary adoption opened in May 2025, newly incorporated companies that register for GST voluntarily came in from November 2025, and all new voluntary GST registrants from April 2026. Existing GST businesses are encouraged to adopt ahead of wider mandates.
