A GST debit note is a document issued by a registered supplier under Section 34(3) of the CGST Act when the taxable value or tax in an invoice is lower than what is actually payable. Rule 53(1A) of the CGST Rules requires the supplier's name, address and GSTIN, the words 'Debit Note', a serial number of up to 16 characters, date, recipient's details and GSTIN, the original invoice number and date, the additional taxable value, rate and amount of tax, and a signature.

When a supplier issues a debit note
- The agreed price was revised upwards after the invoice was issued (for example under a price-variation clause).
- Quantity supplied was more than the quantity billed.
- Tax was charged at a lower rate than applicable, or not charged on a taxable item.
- Recoverable costs such as freight, packing or loading were omitted from the invoice and are payable under the PO.
- Interest or late fee for delayed payment, which Section 15(2)(d) of the CGST Act includes in the value of supply. See the interest on late payment invoice format.
A buyer's 'debit note' for returned goods, rate differences or quality deductions is different. It is an internal commercial document telling the supplier what the buyer has deducted. For the GST effect, the supplier issues a credit note. A buyer cannot reduce the supplier's tax by its own debit note.
How to fill it
- Use a separate series for debit notes (for example DN/25-26/001), unique for the financial year and not more than 16 characters.
- Quote the original invoice number and date. Rule 53 allows one debit note to reference more than one invoice.
- State the reason in one plain sentence and attach the supporting letter, PO clause or calculation.
- Charge tax at the rate of the original supply, with the same CGST/SGST or IGST split as the invoice.
- Report it in GSTR-1 for the month or quarter in which it is issued, and include the amount in the customer's ledger.
- If you are covered by e-invoicing (above the notified turnover limit), report the debit note to the Invoice Registration Portal as well.
Common mistakes
- Issuing a debit note with no reference to any invoice.
- Using the debit note to bill a new supply. A new supply needs a new tax invoice.
- Treating a buyer's debit note as accepted without checking it. If you do not agree with a deduction, reply in writing at once, or the buyer will say you accepted it.
- Forgetting to show the debit note on the next statement of account, so the customer's ledger and yours never match.
How a debit note helps if the buyer does not pay
A debit note issued promptly, with the reason and the supporting document, turns an informal claim (extra freight, price escalation, interest) into a booked, reported receivable. That matters later: a claim that appears in invoices and debit notes, reported in GSTR-1 and visible to the buyer in GSTR-2B, is far harder to deny than an amount first mentioned in a legal notice. Where a buyer disputes a debit note, the dispute is at least on record early, when it can still be resolved.
If the buyer neither pays nor disputes the debit note, include it in the payment reminder and, if needed, the legal notice. FundRaksha Legal handles invoice and debit note recovery on a 30% success fee, nothing upfront.
