Reverse Charge Mechanism (RCM) Under GST: Who Pays, What Documents, How to Claim ITC
Under RCM, the buyer pays GST instead of the supplier. Here is which transactions attract reverse charge, what documents are required, and how to claim ITC.
Overview
A payment voucher is issued under Section 31(3)(g) of the CGST Act by a registered buyer at the time of paying an unregistered supplier in transactions covered by Reverse Charge Mechanism (RCM). Under RCM, the obligation to pay GST shifts from the supplier to the recipient — so the buyer self-charges GST and pays it directly to the government.
The payment voucher acknowledges payment to the supplier and records the GST that the buyer is liable to deposit. It carries the declaration "Tax is payable on reverse charge basis. Recipient is liable to pay GST to the Government."
The buyer reports the RCM liability in Table 3.1(d) of GSTR-3B (not in GSTR-1) and discharges it via cash ledger. To claim the corresponding ITC, the buyer must also issue a Self-Invoice (separate document).

What freelancers say
Switched from Zoho last month — haven't looked back. The CGST/SGST split is automatic, and the one-click GSTR-1 export saves my CA hours at the end of every month.
Had a cross-state client situation I was calculating wrong for months. ZapInvoice just switches to IGST automatically — no more manual guessing, no more wrong invoices.
I bill 15+ clients a month and used to chase every single one. Now ZapInvoice auto-reminds them on day 3, 7 and 14 — most pay before I even notice. Pro pays for itself.
FAQ
Everything you need to know about payment voucher generation.
The registered buyer issues it, to the unregistered supplier, under RCM. This is unique to RCM — in normal supply the supplier issues the invoice.
Yes — to claim ITC on the GST you pay under RCM, you must also issue a Self-Invoice for the same transaction. Payment voucher records the payment; self-invoice supports the ITC claim.
In Table 3.1(d) of GSTR-3B as outward tax payable on reverse charge. The corresponding ITC (subject to eligibility) appears in Table 4(A)(3) of GSTR-3B.
No. Section 9(4) general RCM on unregistered purchases was suspended (currently restricted to specified categories like real-estate). Only notified categories under Section 9(3) attract RCM — legal services, GTA, sponsorship, etc.
For notified RCM supplies, the buyer still self-pays GST and issues a payment voucher — even though the supplier is registered. The supplier issues a tax invoice mentioning "tax payable under reverse charge".
No — under RCM, the unregistered supplier cannot charge GST. They bill the net amount; the buyer deposits the GST separately to the government.
