Why are Overseas Vendor Registration entities excluded from Singapore's InvoiceNow mandate?
Effective: 2025-11-01 · Authority: Inland Revenue Authority of Singapore (IRAS)
Overseas entities registered for Singapore GST under the Overseas Vendor Registration (OVR) regime—including full OVR and Pay-only registrants—are excluded from the IRAS GST InvoiceNow transmission requirement. Additionally, businesses liable for GST registration solely due to the Reverse Charge mechanism are excluded. These exclusions are because InvoiceNow-Ready domestic accounting software is not practically accessible to overseas-based entities.
What is the OVR regime and why are OVR entities excluded?
The OVR regime requires overseas suppliers to register for Singapore GST when they supply digital services to Singapore B2C customers above the registration threshold. OVR entities are excluded from the InvoiceNow transmission requirement because they are overseas-based entities without access to Singapore's domestic InvoiceNow-Ready accounting software ecosystem. The InvoiceNow mandate is designed for domestically established GST registrants that use Singapore-based accounting software connected to IMDA-accredited Access Points.
Why are Reverse Charge registrants excluded?
Businesses that are required to register for Singapore GST solely due to the Reverse Charge mechanism—meaning they account for GST on imported services but do not make their own taxable supplies—are excluded from the InvoiceNow transmission requirement. Their GST registration is an accounting obligation rather than a commercial invoicing obligation, and the InvoiceNow framework is designed to capture outbound tax invoices rather than reverse charge accounting entries.
Frequently Asked Questions
- When will OVR and Reverse Charge registrants be brought into InvoiceNow scope?
- IRAS has indicated that compulsory GST registrants and remaining existing GST businesses will be brought into scope in future phases following further consultation. The specific timeline for including OVR entities or Reverse Charge registrants has not been published. These entities should monitor IRAS announcements for future phase expansions.
- Can an OVR-registered overseas entity voluntarily adopt InvoiceNow?
- The InvoiceNow transmission requires integration with IMDA-accredited Access Points and InvoiceNow-Ready software typically designed for Singapore-based businesses. Overseas entities may face practical barriers to voluntary adoption, though IRAS has not issued specific guidance prohibiting overseas entity participation.
