Get Ready for the GST InvoiceNow Requirement

A significant shift is on the horizon with the introduction of the GST InvoiceNow requirement, a move that underscores the nation's commitment to digital transformation in tax administration. This guide will walk you through what GST InvoiceNow entails, its benefits, and how you can prepare your business for this change.

Overview of GST InvoiceNow Requirement

The GST InvoiceNow Requirement marks a pivotal change in how GST-registered businesses will handle invoicing. Leveraging the nationwide e-invoicing network based on the Peppol standard, this initiative aims to digitalize the invoicing process, making it more efficient, accurate, and streamlined. The requirement for GST-registered businesses to transmit invoice data to the Inland Revenue Authority of Singapore (IRAS) using InvoiceNow solutions is set to be implemented progressively:

  • From 1 November 2025 for newly incorporated companies that voluntarily register for GST.
  • From 1 April 2026 for all new voluntary GST registrants.

A soft launch for early adoption will commence from 1 May 2025, allowing all existing GST-registered businesses to transmit invoice data voluntarily to IRAS using InvoiceNow solutions via the InvoiceNow network.

The Benefits of InvoiceNow Solutions

Adopting InvoiceNow solutions brings a plethora of advantages to your business operations:

1. Streamlined Processes: Direct transmission of e-invoices across different finance systems eliminates manual handling, speeding up the invoicing process.

2. Reduced Errors and Costs: Automation reduces the likelihood of errors and the costs associated with rectifying them. It also cuts down on invoice storage and retrieval expenses.

3. Improved Cash Flow Management: Faster invoice processing and payment times help businesses manage their cash flow more effectively.

By integrating these solutions, businesses can not only meet regulatory requirements but also enhance operational efficiency and focus on growth and innovation.
