Singapore extends GST InvoiceNow Requirement to all GST-registered Businesses (2028-2031)
The Inland Revenue Authority of Singapore (IRAS) and Infocomm Media Development Authority (IMDA) have announced a phased implementation timeline extending the GST InvoiceNow Requirement to all GST-registered businesses in Singapore between April 2028 and April 2031. The announcement was made at the Ministry of Finance Committee of Supply Debate 2026.
InvoiceNow, Singapore`s nationwide e-invoicing network based on Peppol framework, enables the structured exchange of invoice data between finance systems and supports digital tax reporting through direct transmission of invoice data to IRAS. There are currently over 63,000 businesses on the InvoiceNow network utilising a variety of InvoiceNow services offered by IMDA-accredited service providers..
Timeline of the expanded requirement:
- From 1 April 2028, all new compulsory GST registrants and existing GST-registered businesses with annual supplies ≤ $200,000 will be required to transmit invoice data via InvoiceNow to IRAS
- From 1 April 2029, the requirement will cover existing GST-registered businesses with supplies ≤ $1 million
- From 1 April 2030, it will apply to those with supplies ≤ $4 million
- From 1 April 2031, the requirement will apply to all remaining GST-registered businesses with supplies > $4 million
The extended timeline is designed to support a broad adoption of structured eInvoicing while providing sufficient transition time for businesses of varying sizes.
The adoption of structured eInvoicing via InvoiceNow is expected to reduce manual processing effort, improve accuracy, shorten payment cycles, and enhance compliance with GST reporting requirements. With a sizable number of businesses already connected to the InvoiceNow network, the extended mandate will further strengthen the integration of eInvoicing and tax administration in Singapore.
