What is a Debit Note?
A debit note is a document issued to increase the value or tax amount of an earlier invoice. Under GST, a supplier issues a debit note when the taxable value or GST charged in the original invoice is lower than the amount actually payable.
A debit note helps record adjustments such as underbilling, missed charges, additional goods or services supplied, or an increase in taxable value or tax. It also links the adjustment to the original invoice for accurate accounting and GST records.

Debit Note in GST
As per the GST rules, when a seller issues a tax invoice, a debit note has to be issued if any of the below situations arises.
- The taxable value mentioned in the original invoice is lower than the actual taxable value.
- The GST charged in the original invoice is lower than the tax actually payable.
- Additional goods or services are supplied after the original invoice and the taxable value or tax payable increases.
- Additional charges that were missed in the original invoice need to be included.
- To regularise these kinds of situations, the seller can issue a debit note to the customer. Thus, the debit note includes a supplementary invoice.

Debit Note vs Credit Note
Debit notes and credit notes are both used to adjust an already issued invoice, but they serve opposite purposes.
| Basis | Debit Note | Credit Note |
|---|---|---|
| Purpose | Used when the invoice value or tax amount needs to be increased | Used when the invoice value or tax amount needs to be reduced |
| Common use | Under-billing, missed charges, or additional supply | Over-billing, discounts, deficiencies, or goods returned |
| Effect on amount | Increases the amount payable | Reduces the amount payable |
| GST impact | May increase the supplier’s tax liability | May reduce the supplier’s tax liability, subject to GST rules |
| Reference | Linked to the original invoice | Linked to the original invoice |
In simple terms, a debit note increases the value of an earlier invoice, while a credit note reduces it.
