AEO Quick Answer & Key Takeaway

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.

Understanding Section 9(3) and 9(4) RCM

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.

Cross-Period Credit Notes in GSTR-2B

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.

Discharging RCM via the Electronic Cash Ledger

Werkora isolates RCM-applicable purchase transactions, maintains structured consecutive voucher numbering, and tracks tax obligations to ensure accurate statutory reporting.

Frequently Asked Questions

Expert Answers for Factory Operations

Can RCM liability be offset using existing Input Tax Credit balance?

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.

Can the paid RCM tax be claimed as ITC?

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.
