Worked examples — five live scenarios
Example 1 — Sales return credit note
Facts: Supply on 1-Aug-2025, Rs. 1 lakh + 18% GST. Customer returned defective goods 15-Sep. Supplier issued credit note 16-Sep.
Analysis: Sub-s. (1)(b) — goods returned. Credit note issued. Rule 53 particulars + reference to original invoice. GSTR-1 September reporting. Tax liability reduced by Rs. 18,000. Unjust-enrichment framework — verify whether customer claimed ITC + passed on.
Result: Standard credit-note framework.
Example 2 — Outer-limit breach
Facts: FY 2024-25 supply with invoice excess. Credit note attempted in Dec-2025.
Analysis: Sub-s. (2) — 30-November 2025 outer limit. Beyond. Credit note ineffective for output-tax reduction. Practitioner advice — observe 30-November discipline.
Result: Outer-limit framework operates.
Example 3 — Unjust-enrichment bar
Facts: Supplier wants to issue credit note for past-FY supply. Customer (B2C) has already paid + consumed. Incidence passed on.
Analysis: Sub-s. (2) proviso + Mafatlal framework — incidence passed on. Supplier's output-tax reduction barred. Refund (if any) goes to Consumer Welfare Fund under s. 57.

Example 4 — Debit note (no outer limit)
Facts: FY 2023-24 supply with invoice undercharge. Discovered in 2025. Debit note issued.
Analysis: Sub-s. (3) — value/tax less than payable. Debit note. Sub-s. (4) — report in month of issuance. No 30-November outer limit. Tax liability + interest from original date.
Result: Debit note framework — no outer limit.
Example 5 — Recipient ITC adjustment
Facts: Customer received credit note from supplier. Need to reverse ITC.
