What is GST InvoiceNow Requirements?
InvoiceNow is Singapore’s nationwide e-invoicing network based on Peppol standard. Introduced by the Infocomm Media Development Authority (“IMDA”) in 2019, InvoiceNow enables businesses to easily send and receive invoices in a structured digital format. More information on the benefits of InvoiceNow is available on IMDA’s InvoiceNow webpage.
To support the nationwide InvoiceNow initiative and IRAS’s efforts to digitalise tax administration, GST-registered businesses will be required to transmit invoice data to IRAS using InvoiceNow-Ready Solutions. This will be mandated in phases.
•Total annual supplies refer to the total value of standard-rated, zero-rated and exempt supplies made in all the prescribed accounting periods ending in calendar year 2025.
• GST InvoiceNow implementation timeline has been announced by IRAS. Businesses should review their applicable implementation date and begin preparing early to ensure smooth transition.
• IRAS will inform GST-registered businesses that were registered before 2026 of their respective mandatory implementation date by mid-2026. In the meantime, existing GST-registered businesses may self-help and use the Excel calculator to determine their applicable implementation date: GST InvoiceNow Implementation Date Calculator (XLSX, 48.9KB)
