If your credit note genuinely reduced the taxable value or GST payable on the original supply, the customer’s ITC must be reduced to the corresponding extent. Under section 34(2) of the CGST Act, the supplier’s output-tax reduction is conditional on the recipient reversing the attributable ITC (or not having availed it). The customer should therefore reverse the excess ITC and pay any applicable interest, then respond to the notice with the credit note, your GSTR-1/GSTR-3B evidence and proof of the reversal/payment. The customer’s debit note without GST does not, by itself, remove this requirement.
You need not issue an auditor-certified declaration merely because the department has requested one. The customer can explain that the supplier’s credit note was reported and the related ITC has been reversed, supporting this with available records. If the customer disputes the credit note’s tax treatment or the notice seeks a prescribed declaration under a specific provision or procedure, the notice’s exact wording and tax period should be checked before responding.
This issue is best handled by reconciling the credit note, supplier tax reduction and recipient ITC reversal for the relevant period.
