New GST Rule: Mandatory InvoiceNow Adoption
2026-09-14



Singapore’s Inland Revenue Authority of Singapore (IRAS) is rolling out a progressive national electronic invoicing initiative, InvoiceNow. Starting from 1 April 2026, all newly GST-registered businesses in Singapore will be required to adopt the InvoiceNow platform to submit official invoice data to IRAS, marking a major upgrade to the country’s corporate tax compliance framework.


Phased Implementation Timeline

IRAS has introduced a three-phase rollout to help businesses adapt to the new digital invoicing standard smoothly:

- 1 May 2025: All existing GST-registered businesses may voluntarily adopt and trial the InvoiceNow system.

- 1 November 2025: Newly incorporated GST-registered companies (established within six months prior to GST registration) are eligible for voluntary adoption.

- 1 April 2026: Mandatory enforcement for all newly GST-registered businesses. InvoiceNow usage becomes a compulsory compliance requirement.


Key Benefits of InvoiceNow

Powered by Singapore’s nationwide Peppol electronic delivery network, InvoiceNow enables seamless transmission of structured digital invoices across different corporate accounting systems.

Businesses no longer need to manually input supplier invoice data into internal accounting software. All verified invoice records are automatically synced to IRAS’ official database. The digital framework significantly optimises corporate financial workflows with higher efficiency, fewer human errors, enhanced data security and fully streamlined tax reporting procedures.


Critical Compliance Updates

The latest IRAS official guidelines have revised the data submission scope for electronic invoices. Under the new regulations, certain invoice particulars are mandatory for submission, while other categories are exempted from reporting to IRAS.

GST-registered businesses must strictly distinguish between required and exempt data to avoid compliance violations, reporting errors and potential regulatory penalties.
