When reverse charge applies
Reverse charge shifts the duty to pay GST from the supplier to the recipient. It covers specific notified services (legal, GTA, security) and all imports of services — the most common being foreign advertising (Meta, Google) and cloud/SaaS (AWS, GCP, Azure). You self-account for the GST and pay it directly.
Indian SaaS context: This is the single biggest source of invoice confusion for Indian startups: a Meta Ads bill has no Indian GST line, yet you still owe 18% under RCM. Pay the vendor in full, deposit the RCM GST, and claim it back as input tax credit if the spend is for business.
Frequently asked questions
What is reverse charge (RCM)?+
Normally the supplier collects GST and pays it to the government. Under reverse charge the recipient pays the GST directly instead. It applies to notified services and to imports of services — like buying ads from Meta or cloud from AWS.
Do I pay extra to the vendor under RCM?+
No. You pay the vendor their invoice amount as usual, and separately pay the RCM GST to the government. If the expense is for business, you can usually claim that GST back as input tax credit — so the net cost is often nil.
Why do foreign ads and SaaS trigger RCM?+
Buying advertising or software from a foreign provider with no Indian GST registration is an 'import of services'. GST still applies, so the law makes you (the recipient) account for it under reverse charge at 18%.
