17.10.2026: GSTN Introduces RCMDOM and RCMIMP Supply Types for e-Invoicing of Recipient-Generated Self-Invoices under RCM

GST

GSTN has announced an enhancement to the existing e-invoicing framework to facilitate the reporting of recipient-generated self-invoices for specified domestic supplies received from unregistered persons and imports of services, where the registered recipient is liable to pay GST under the Reverse Charge Mechanism (RCM).

The announcement follows the recommendation made at the 57th GST Council meeting and introduces two new supply type codes, namely RCMDOM and RCMIMP. The facility is intended for registered taxpayers having Aggregate Annual Turnover (AATO) of ₹5 crore and above, subject to the applicable statutory provisions and government notifications.

The development seeks to extend the Invoice Registration Portal (IRP) reporting mechanism to specified transactions in which the registered recipient, rather than the supplier, generates the self-invoice.

2. New supply types introduced

Supply type Scope
RCMDOM Recipient-generated self-invoices for specified domestic supplies received from unregistered suppliers, where GST is payable by the registered recipient under RCM.
RCMIMP Recipient-generated self-invoices for imports of services from suppliers located outside India, where GST is payable by the registered recipient under RCM.

Under the enhanced framework, eligible registered recipients will be able to report the relevant self-invoices through an authorised IRP by selecting the appropriate supply type. Upon successful validation of the prescribed invoice particulars, an Invoice Reference Number (IRN) will be generated in accordance with the applicable technical specifications.

3. Legal significance and implications for taxpayers

A. Integration of self-invoices with the e-invoicing framework

Under Section 31(3)(f) and Section 31(3)(g) of the CGST Act, 2017, a registered person liable to pay tax under RCM is required to issue an invoice in respect of specified supplies received from an unregistered supplier and a payment voucher when making payment to a supplier in cases covered by the relevant provisions.

The proposed functionality introduces a mechanism for reporting these recipient-generated self-invoices through the IRP. This is a significant technological development because the reporting framework is being extended beyond the conventional model of supplier-generated e-invoices.

B. Implications for domestic RCM transactions

For specified domestic supplies received from unregistered persons, eligible taxpayers will need to assess whether the transaction falls within the scope of the applicable self-invoicing and e-invoicing requirements. Where applicable, the RCMDOM supply type will be relevant for reporting the self-invoice.

C. Implications for import of services

The RCMIMP category is intended to facilitate reporting of self-invoices relating to imports of services on which the registered recipient is liable to pay GST under RCM. Businesses importing services from overseas vendors should evaluate the impact on their invoice-generation processes, accounting systems and tax compliance workflows.

D. Turnover threshold and statutory applicability

The announcement identifies registered taxpayers with AATO of ₹5 crore and above as the intended category. However, the announcement does not, by itself, establish the effective date or conclusively determine the precise legal scope of the mandatory reporting requirement. These aspects remain subject to the applicable notifications, statutory provisions and subsequent implementation instructions.

4. Sandbox testing and implementation readiness

The new supply types have been implemented in the sandbox environments of all six authorised IRPs:

  • NIC IRP-1 and NIC IRP-2

  • Cygnet IRP-3

  • Clear IRP-4

  • EY IRP-5

  • IRIS IRP-6

The common technical specifications, business validations and validation codes are to be aligned across all six IRPs in accordance with the release note issued by NIC IRP-1.

Taxpayers, GST Suvidha Providers (GSPs), Application Service Providers (ASPs), ERP vendors and other integration partners can use the sandbox environments to test the new functionality and prepare their systems for integration.

The production rollout date and commencement of the associated reporting requirements have not yet been announced in the communication.

5. Action points for businesses and professionals

Registered taxpayers and their GST advisors should consider the following preparatory measures:

  1. Identify relevant transactions: Review domestic purchases from unregistered suppliers and imports of services that attract RCM.

  2. Check turnover eligibility: Determine whether the business falls within the stated AATO threshold, while separately verifying the applicable statutory conditions.

  3. Review ERP and accounting systems: Assess whether the systems can generate recipient-issued self-invoices and report the required data to an authorised IRP.

  4. Coordinate with technology partners: Inform ERP vendors, GSPs and ASPs about the new RCMDOM and RCMIMP supply types.

  5. Undertake sandbox testing: Test invoice-data mapping, validation rules, error handling and IRN generation after reviewing the detailed release note.

  6. Monitor official updates: Track subsequent notifications, implementation guidelines, validation specifications and the production rollout announcement.

6. Important distinction: e-invoicing does not replace underlying GST compliance

The introduction of these supply types is a reporting and system enhancement. It should not be interpreted as changing the substantive conditions governing the levy of GST under RCM, the obligation to issue self-invoices, the time of supply, payment of tax or eligibility to claim input tax credit.

Businesses must continue to evaluate the relevant provisions of the CGST Act, the CGST Rules and applicable notifications independently of the availability of IRN generation.
