Credit Note

Definition

A credit note is a document issued by the seller (supplier) to the buyer, reducing the value of a previously issued tax invoice. The supplier issues a credit note when goods originally supplied are returned by the buyer, the taxable value or tax charged in the original invoice exceeds the actual taxable value or tax payable, or the goods or services supplied are found to be deficient in quality or quantity. The credit note effectively reduces the supplier's receivable and the buyer's payable for that transaction.

Under Section 34 of the CGST Act, 2017, credit notes must be declared in the GST return for the month in which the credit note is issued. The supplier's output tax liability is reduced by the tax amount in the credit note, and correspondingly, the buyer's input tax credit is reduced. Credit notes must be issued before 30th November of the financial year following the year in which the original invoice was issued, or the date of filing the annual return, whichever is earlier. Each credit note must reference the original invoice number and contain all mandatory fields specified under GST rules.

In accounts payable, credit notes received from vendors must be matched against the original invoice, applied to the vendor's ledger balance, and factored into payment calculations. A common challenge is timing: if a payment has already been made on the full invoice amount before the credit note is received, the AP team must track the credit and adjust it against future payments. Automated AP systems handle this by maintaining vendor-level credit balances that are automatically applied to subsequent invoices.

• Reduces the supplier's output tax liability and the buyer's input tax credit proportionally
• Must be issued before 30th November of the following financial year
• Must reference the original invoice number and contain all GST-mandated fields
• AP systems should track vendor credit balances and auto-apply to future payments
