This is an excellent query involving Section 15(3)(b) of the CGST Act, treatment of commercial credit notes, GST credit notes, and the implications on ITC accumulation. Let's address your queries step-by-step:
✅ FACTUAL SUMMARY
Manufacturer to Distributor:
Qty: 1000 kg @ ₹360/kg + 12% GST = ₹4,03,200 (₹3,60,000 + ₹43,200 GST)
Distributor gets ITC: ₹43,200
Month-end discount of ₹60/kg based on agreement → ₹60,000 total discount (no GST in credit note)
Distributor to Customer:
Sells @ ₹310/kg (i.e., ₹300 + ₹10 margin) + 12% GST
Value: ₹3,10,000 + ₹37,200 GST
Output tax liability: ₹37,200
ITC vs. Output:
ITC = ₹43,200
Output GST = ₹37,200
Surplus ITC: ₹6,000
🔍 QUERY 1: Can you issue a commercial credit note or must it be a GST credit note?
Legal Background – Section 15(3)(b)CGST Act:
A supplier can reduce the value of supply via GST credit note only if:
"(b) the value of the supply is reduced by the supplier by issue of a credit note [in respect of discount], subject to the following conditions:
(i) such discount is established in terms of an agreement entered into at or before the time of such supply; and
(ii) such discount is specifically linked to relevant invoices; and
(iii) input tax credit attributable to the discount has been reversed by the recipient of the supply."
✅ In your case:
Condition (i): Met → Pre-agreed monthly discount (Quick Payment Scheme)
Condition (ii): Met → Credit note is linked to original invoice
Condition (iii): NOT MET → Distributor is not reversing ITC of ₹43,200
❌ Therefore, you cannot issue a GST credit note unless ITC is reversed by the distributor.
✅ You can issue a commercial credit note (without GST), but this will not adjust your GST liability. It simply adjusts the financial consideration between supplier and distributor, but has no impact on the tax already paid.
🔍 QUERY 2: Will this result in loss to the government due to ITC accumulation?
✔️ Answer: Not a loss, but working capital inefficiency for the government.
The government has collected ₹43,200 from the supplier as GST
The distributor has only paid ₹37,200 as output tax
The leftover ₹6,000 remains as ITC in distributor's ledger – not refunded unless under refund category (e.g., inverted duty structure or zero-rated exports)
So technically:
No loss to government – tax was paid and not refunded
However, it leads to accumulation of credit in the hands of the distributor, which:
Hurts working capital
May prompt refund applications under eligible circumstances
✅ Recommendation:
Issue a commercial credit note without GST
Ensure distributor does NOT reverse ITC if you’re not issuing a GST credit note
Document clearly that it is a financial discount, not a post-supply taxable adjustment
If your intent is to adjust GST liability, the distributor must reverse proportionate ITC, and a GST credit note should be issued.
📌 Optional Strategy (if workable):
To avoid ITC buildup, consider offering pre-invoice discounts or modifying the billing rate upfront to ₹300 and reflecting distributor margin separately.
