GST under RCM applies when you import services from outside India, which includes cloud services from AWS, Google Cloud, Azure, or any foreign OIDAR service provider.
Here is how it works in practice:
Rate: 18% IGST on the invoice amount (converted to INR at the date of payment or the RBI reference rate for the month).
What you need to do each month:
- Raise a self-invoice in your own name for the cloud service payment.
- Report it in GSTR-1 under Table 4B (outward supplies by a registered taxpayer where tax is paid under RCM).
- Pay the IGST through your Electronic Cash Ledger via your GSTR-3B filing.
- Claim this IGST as ITC in the same or subsequent GSTR-3B filing (under Table 4A(3) - inward supplies under RCM).
For registered businesses, the net GST cost is usually nil because the RCM paid gets fully offset as ITC. The main obligation is the compliance: raise the self-invoice, report, pay, and claim.
Composition dealers cannot claim ITC on RCM and the cost sticks.
