Mandatory adoption of GST InvoiceNow

IRAS will progressively require GST-registered businesses to transmit invoice data using InvoiceNow-Ready Solutions via the InvoiceNow network. This marks a fundamental shift in how invoices are issued, captured, and reported for GST purposes.

Businesses should assess their readiness early to ensure a smooth transition and compliance with the upcoming requirements.

Mandatory participation will be implemented progressively, in the following phases.
