Prepare early and adopt the GST InvoiceNow Requirement from 1 May 2025

All GST-registered businesses will soon be required to transmit invoice data to IRAS using InvoiceNow-Ready Solutions via the InvoiceNow network.

We encourage all existing GST-registered businesses as well as any other businesses applying for GST registration on/after 1 May 2025 to be early adopters of the soft launch from 1 May 2025. By coming onboard early, you will enjoy the InvoiceNow benefits sooner as compared to staying on traditional paper or PDF-based invoicing.

For businesses that want to be GST-registered on a voluntary basis, they will be required to adopt the GST InvoiceNow Requirement. These include businesses which are:

Newly incorporated companies (incorporated within 6 months from the time they submit their application for GST registration) that apply for voluntary GST registration from 1 Nov 2025
Any business that applies for voluntary GST registration from 1 Apr 2026, regardless of incorporation date or business constitution

There are plans to progressively extend mandatory participation to new compulsory GST registrants and remaining GST-registered businesses. We will continue to consult industry partners and carefully review the feedback received before announcing further details.

Approach your IRSP and/or AP to register the business in the SG Peppol Directory with your UEN and obtain your Peppol ID.
