From 1 January 2027, businesses already covered by India’s GST e-invoicing regime will also have to digitally report qualifying reverse-charge purchases from unregistered suppliers and imports of services.
India’s tax authorities have widened the scope of GST e-invoicing, bringing certain inward supplies under reverse charge, as well as imports of services, into the digital reporting net from 1 January 2027. According to Notification No. 04/2026-Central Tax, issued by the Central Board of Indirect Taxes and Customs on 26 October 2026, the change amends the existing e-invoicing framework under Rule 48(4) of the CGST Rules and expands the categories of transactions that must be covered by an invoice reference number.
Until now, e-invoicing has mainly been associated with outward supplies, especially business-to-business sales and exports. The revised notification keeps those categories in place but adds two further classes of transactions: supplies received from an unregistered person where the recipient must pay tax under the reverse charge mechanism, and imports of services. The result is that some purchase-side transactions, not just sales invoices, will now have to pass through the e-invoicing system for businesses already within its scope.
The practical effect is likely to be felt most sharply by finance and tax teams. As Taxo Online and Jurishour both noted, the amendment does not change the turnover threshold that determines whether a business is otherwise subject to e-invoicing, nor does it create a fresh reverse charge levy. Instead, it extends the reporting requirement to transactions where reverse charge liability already exists under the GST law. The notification also introduces new supply-type codes, RCMDOM for domestic supplies from unregistered persons under reverse charge and RCMIMP for imports of services, signalling that accounting systems will need to distinguish these entries from standard purchases.
That distinction matters because businesses will need to map inward supplies more carefully than before. Jurishour reported that the amendment should not be read as applying to every purchase from an unregistered supplier; the reverse charge condition must also be satisfied. For companies that receive consultancy, software, cloud or other cross-border business services from overseas vendors, the import-of-services category will be especially important. The move effectively brings accounts payable into a compliance process that has long been focused on outward invoices alone.
Businesses covered by e-invoicing are likely to need a fresh review of supplier masters, self-invoicing processes and ERP configurations before the new rules take effect. Casansaar and Patron Accounting both highlighted the need to check whether systems can identify reverse charge transactions, separate import-of-services entries and generate the required reporting correctly. The broader policy direction is clear: tax authorities are seeking more detailed digital visibility over both sales and purchases, tightening transaction-level monitoring ahead of the 1 January 2027 start date.
