Reverse Charge Mechanism (RCM) supplies under Section 9(3) and 9(4) require the buyer to discharge tax in cash before claiming ITC in the same month. Furthermore, supplier credit notes reported in subsequent periods reduce net ITC in GSTR-2B. Werkora tracks RCM self-invoices and cross-period credit notes automatically.
Manufacturers routinely incur RCM expenses: Goods Transport Agency (GTA) freight payments, legal fees from advocates, and security agency contracts. Under Section 9(3), the recipient is statutorily liable to pay the GST. For unregistered vendors, Section 31(3)(f) mandates that the recipient issue a self-invoice.
When a supplier issues a credit note in July for an invoice issued in April, Table 4 of GSTR-2B reports a negative credit. If the manufacturer does not have sufficient fresh inward credit in July from that supplier, the credit note reduces total available ITC across all categories, requiring accurate general ledger matching.
Werkora isolates RCM-applicable purchase transactions, maintains structured consecutive voucher numbering, and tracks tax obligations to ensure accurate statutory reporting.
Werkora equips every shop-floor supervisor, line operator, storekeeper, and accountant with their own dedicated login with plans sized for your operation.
No. Section 49(4) requires that reverse charge liability must be paid strictly in cash through the electronic cash ledger. It cannot be adjusted against electronic credit ledger balances.
Yes. Once paid in cash, the tax amount becomes fully eligible for Input Tax Credit in the same tax period, subject to Section 17(5) restrictions.
