GST InvoiceNow Requirement

GST-registered businesses will be required to transmit invoice data to IRAS using InvoiceNow-Ready Solutions via the InvoiceNow network. This mandatory participation will be implemented progressively:

From 1 November 2025, for newly incorporated companies that register for GST voluntarily.
From 1 April 2026, for all new voluntary GST-registrants.

A soft launch for early adoption will commence from 1 May 2025. IRAS encourages all GST-registered businesses and businesses applying for GST registration on/after 1 May 2025 to transmit their invoice data to IRAS using InvoiceNow-Ready Solutions via the InvoiceNow network.

There are plans to progressively extend mandatory participation to new compulsory GST registrants and existing GST-registered businesses.

Businesses can seek support from IRAS or IMDA in their adoption of InvoiceNow. For more information on the implementation of InvoiceNow for GST-registered businesses, please refer to the IRAS webpage and IMDA webpage.
