InvoiceNow, Singapore’s Peppol-based e-invoicing network, ran for years as a voluntary programme. The GST InvoiceNow Requirement changes that: GST-registered businesses transmit invoice data to IRAS through InvoiceNow, starting with new voluntary registrants and widening from there.
IMDA launches the nationwide e-invoicing network on Peppol, open to businesses of every size on a voluntary basis.
GST-registered businesses can begin transmitting invoice data to IRAS through InvoiceNow voluntarily.
Newly incorporated companies that register for GST voluntarily must transmit through InvoiceNow.
The requirement extends to every new voluntary GST registrant.
IRAS has signalled a progressive extension to existing GST-registered businesses. Dates for that wider rollout are the ones to watch.
Phase dates are set by IRAS and may be refined. Confirm the dates and scope that apply to your business against IRAS guidance.
The point of the requirement is the copy that reaches IRAS. That is what makes it a GST obligation rather than an e-invoicing preference.
Invoice data travels through an accounting system or service connected to the network via an IMDA-accredited access point.
A copy of the invoice data goes to IRAS — the “fifth corner” on top of the usual four-corner exchange.
Your customers do not all need to be on InvoiceNow. The obligation is about the data reaching IRAS.
Structured data to the Peppol International specification for Singapore.
Businesses are addressed on the network by an identifier derived from their Unique Entity Number.
GST at the current 9% standard rate, carried correctly per line, alongside zero-rated and exempt supplies.
