India's Central Board of Indirect Taxes and Customs (CBIC) has confirmed the extension of mandatory e-invoicing to recipient-generated self-invoices under the Reverse Charge Mechanism (RCM), effective January 1, 2027. The expansion, established through Notification No. 04/2026–Central Tax dated October 26, 2026, covers specified domestic supplies received from unregistered persons and imports of services.
Implementation timeline for India's RCM e-invoicing requirements
The new requirements will take effect on 1 January 2027, following the GSTN advisory issued on October 16, 2026. The functionality is currently available for testing in the sandbox environments of all six authorised Invoice Registration Portals (IRPs), while further production implementation guidance may be communicated separately.
What India's RCM e-invoicing changes mean for businesses
The extension broadens India's existing e-invoicing framework beyond supplier-issued invoices to include recipient-generated self-invoices for specified transactions subject to RCM, where the recipient is responsible for paying GST.
The changes apply to registered taxpayers with an Aggregate Annual Turnover (AATO) of ₹5 crore (INR 50 million) or more and introduce two new supply types:
- RCMDOM: Covers recipient-generated self-invoices for specified domestic supplies received from unregistered persons where GST is payable by the recipient under RCM.
- RCMIMP: Covers recipient-generated self-invoices for imports of services from suppliers located outside India where GST is payable by the recipient under RCM.
Under the expanded framework, affected taxpayers will be required to report the relevant self-invoices through an authorised IRP using the appropriate supply type code. Following successful submission and validation, an Invoice Reference Number (IRN) will be generated.
The necessary functionality has already been implemented in the sandbox environments of all six authorised IRPs, allowing taxpayers and integration providers to test their systems ahead of implementation.
Businesses meeting the turnover threshold and engaging in transactions covered by the new requirements should review their RCM invoicing processes and assess whether their ERP and e-invoicing solutions can support the new supply types. With the January 1, 2027 effective date confirmed, early integration and testing will be important to ensure compliance with the expanded reporting obligations.
