New GST Invoice Now Rule for GST-Registered Businesses

InvoiceNow is a national e-invoicing system that helps businesses of all sizes process invoices more efficiently, lowering costs and speeding up payments. It uses the Peppol framework, which allows e-invoices to be sent in a standard digital format between different finance systems. InvoiceNow was launched by the Infocomm Media Development Authority (IMDA) in 2019.

To support the nationwide InvoiceNow initiative and IRAS’s efforts to go digital, GST-registered businesses will need to use InvoiceNow solutions to send their invoice data to IRAS for tax purposes. This will help integrate tax into businesses' accounting and payroll systems more smoothly.

Step-by-step adoption of GST InvoiceNow Requirement

To give businesses enough time to get ready, the GST InvoiceNow Requirement will be rolled out in stages:

*This applies to existing GST-registered businesses and any other businesses that apply for GST registration on or after 1 May 2025.

The GST InvoiceNow Requirement will be gradually implemented for the remaining GST-registered businesses. IRAS will consult with industry partners and review feedback before sharing more details. While the initial phases mainly impact new voluntary GST registrants, all existing GST-registered businesses should be aware of these dates if they plan to start new businesses or apply for voluntary GST registration.

Advantages of Using InvoiceNow Solutions

Invoice data will be sent to IRAS smoothly through Access Point providers (AP) using Application Programming Interface (API) technology. By sending invoice data directly through the InvoiceNow network, GST-registered businesses can simplify their compliance process when submitting data to IRAS.

With improved risk analysis from IRAS, fewer businesses are likely to be chosen for GST audits. Those that are selected may experience shorter audits and quicker resolution of any issues. Businesses claiming GST refunds might also receive their refunds sooner if they are assessed as lower risk.

Additionally, businesses can benefit from features in InvoiceNow solutions, such as receiving alerts for incorrect GST charges from suppliers who are not GST registered.
