Under Section 34(1) of the CGST Act, 2017 a supplier may issue a credit note where a tax invoice overstates the taxable value or tax, where goods are returned, or where goods or services are found deficient. The credit note must be declared in the return for the month it is issued and not later than 30 November following the end of the financial year of the supply (or the date of the annual return, if earlier), to reduce the supplier's output tax; the buyer must correspondingly reverse ITC. A credit note reduces the recoverable balance by its amount.
How credit notes work in India
The supplier issues the credit note referencing the original invoice, with the reduced value and GST, reports it in GSTR-1, and its output tax for the month falls. The buyer sees it in GSTR-2B and reverses the ITC. Financial credit notes (commercial discounts with no GST adjustment) are also common; they reduce the receivable but not the tax. In trade disputes, buyers often demand a credit note to "settle" a deduction they have already made. If the supplier agrees, the credit note closes the matter; if not, the supplier should refuse and claim the full invoice.
| Situation | Right document |
|---|---|
| Goods returned and accepted back | GST credit note |
| Agreed post-sale discount (pre-agreed terms) | GST credit note |
| Commercial goodwill discount, no GST change | Financial credit note |
| Disputed deduction by buyer | Written rejection; no credit note |
Why it matters for getting paid
A credit note issued under pressure converts a disputed deduction into an agreed one, permanently. Many suppliers lose 5% to 10% of their receivables this way every year. The right response to an unjustified deduction is a written rejection and, if needed, a legal notice for the full amount. See debit note, credit note dispute and statement of account.
How FundRaksha uses it
FundRaksha's advocates check every credit note in the client's ledger: those issued for genuine returns are reflected in the claim; those extracted by buyers for unproven deductions are examined to see whether they were made under protest. Clients are advised on a credit note policy going forward. The fee is 30% of recovery, and 60% of cases settle before court.
Worked example (hypothetical)
A Tiruppur garment exporter invoices a Delhi retailer ₹12,00,000 plus GST in October. The retailer returns ₹1,00,000 of garments in November with a returns challan; the exporter issues a GST credit note for ₹1,00,000 plus GST and reports it in November's GSTR-1, well within the 30 November deadline of the following year. The retailer then asks for a further ₹80,000 credit note for "markdown support" never agreed. The exporter refuses in writing. The recoverable balance is ₹11,00,000 plus GST; the notice claims this with interest and the retailer pays, dropping the markdown demand.
