India Introduces RCMDOM and RCMIMP E-Invoicing Codes for Reverse-Charge Mechanism
India's Goods and Services Tax Network has added two new supply type codes, RCMDOM and RCMIMP, to its e-invoicing system for recipient-generated self-invoices under the reverse-charge mechanism. These codes became operational on 18 October 2026.
Key takeaways
- GSTN introduced two new supply type codes, RCMDOM and RCMIMP, on 17 October 2026.
- These codes facilitate recipient-generated self-invoices under the reverse-charge mechanism (RCM).
- Both codes are active and operational within the GSTN e-invoicing system as of 18 October 2026.
Context
The introduction of RCMDOM and RCMIMP marks a significant expansion of India's e-invoicing mandate, which has steadily grown to encompass more transaction types and taxpayer categories. The reverse-charge mechanism (RCM) is a tax arrangement where the recipient of goods or services, rather than the supplier, is responsible for remitting GST to the government. Prior to this update, there was no standardized electronic reporting pathway for recipient-generated self-invoices under RCM. The new codes address this gap by codifying these transactions within the e-invoicing schema.
The distinction between RCMDOM and RCMIMP appears to reflect the origin of the supply. RCMDOM likely pertains to domestic RCM transactions, while RCMIMP seems to address import-related RCM scenarios. However, the source material does not provide detailed eligibility criteria, technical implementation guidance, or the precise scope of each code.
What's Changing
As of 18 October 2026, both RCMDOM and RCMIMP are active and operational within the GSTN e-invoicing system. This development is notable as it represents the first documented introduction of dedicated supply type codes for RCM-based self-invoicing by recipients in India's digital tax infrastructure. The introduction of these codes is part of GSTN's ongoing efforts to enhance the e-invoicing framework and ensure comprehensive digital compliance.
Implications for Taxpayers
The new supply type codes will primarily impact businesses involved in transactions where the reverse-charge mechanism applies. This includes both domestic and import-related scenarios. Taxpayers involved in these transactions will need to ensure they are using the correct supply type codes when generating self-invoices. The exact impact on specific sectors or taxpayer turnover thresholds is not specified in the source material, so further regulatory guidance from GSTN or the Central Board of Indirect Taxes and Customs (CBIC) should be monitored.
Outlook
The introduction of RCMDOM and RCMIMP is a step towards more comprehensive digital compliance in India's GST regime. However, the source material lacks detailed implementation timelines and specific guidance on eligibility criteria. Taxpayers should expect further regulatory updates from GSTN or CBIC to clarify the scope and requirements of these new codes. Monitoring these developments will be crucial for ensuring compliance with India's evolving e-invoicing mandate.
