by | Mar 11, 2025 | Accounting, Goods and Services Tax, Tech News

The Inland Revenue Authority of Singapore (IRAS) has formalised requirements for GST-registered businesses to adopt the nationwide InvoiceNow (Peppol) network for transmitting invoice data.

On 7 March 2025, IRAS published the definitive e-Tax Guide “GST: Adopting GST InvoiceNow Requirement for GST-registered Businesses”. This guide supersedes the draft version previously subject to public consultation, for which IRAS published its responses on 20 November 2024.

Key Mandates Outlined in the Guide:

  1. Mandatory Scope: The guide specifies the categories of transactions where electronic transmission of invoice data via InvoiceNow is compulsory. It also details specific transaction types explicitly excluded from this requirement.
  2. Transmission Deadline: Businesses must comply with stipulated deadlines for transmitting invoice data to IRAS after issuing a tax invoice.
  3. Exemptions: Certain types of GST-registered businesses are formally excluded from the InvoiceNow mandate. The guide clarifies the eligibility criteria for these exemptions.

Phased Implementation Schedule:

  • Soft Launch (Early Adoption): Commences 1 May 2025, allowing businesses to voluntarily adopt the system ahead of mandatory deadlines.
  • Condition for Voluntary Registration: Adoption of the GST InvoiceNow Requirement will become an additional mandatory condition for businesses applying for voluntary GST registration. Details on the effective date for this condition are pending.
  • Mandatory Rollout: IRAS will enforce mandatory adoption for:
    • New businesses registering for GST compulsorily.
    • All remaining existing GST-registered businesses not covered by exemptions.
    • Further details and timelines for this mandatory phase will be announced following industry consultation.

GST-registered businesses, particularly those considering voluntary registration or nearing compulsory registration thresholds, are advised to review the official e-Tax Guide and assess their readiness to integrate with the InvoiceNow (Peppol) network. Preparation for the soft launch beginning 1 May 2025 is recommended.
