How to make a debit note

Enter the original invoice number and date.
Pick the reason: price increased, extra quantity supplied, or a correction.
Add only the difference. For example, one line for “Rate difference on INV-042” at the same GST rate.
Set a due date if the customer should pay the extra amount by a certain day, then download or email it.

Frequently asked questions

When is a debit note issued under GST?

When the taxable value or tax on an invoice was less than it should have been: you undercharged the price, supplied more quantity than invoiced, or need to correct an error upwards. The debit note adds the difference and the GST on it.

Who issues a debit note, the buyer or the seller?

Under GST, the supplier issues the debit note to increase the amount due. In everyday business, buyers also send “debit notes” to suppliers for returns, but for GST purposes the supplier’s credit note is what reduces tax in that case.

What must a debit note contain?

Your name, address and GSTIN; the words “Debit Note”; a serial number of up to 16 characters and the date; the recipient’s details and GSTIN; the number and date of the related invoice; the value, GST rate and tax amount; and a signature.

Does a debit note increase my GST liability?

Yes. Report it in GSTR-1 for the month it is issued and pay GST on the extra value. Your customer can claim input tax credit on it.
