  • Discounts or Allowances: The seller granted a discount or allowance to the buyer

When should you use a debit note and a credit note?

Let us understand when to issue debit and credit notes, which helps businesses maintain transparency and correct transaction details.

Scenarios for issuing a debit note
  1. Overcharging
    A debit note can be issued when a seller charges a customer more than the agreed-upon amount. For example, if a customer is charged $150 for a product that was listed at $120, the seller would issue a debit note for $30 to credit the customer’s account.
  2. Returned Goods
    Another scenario to issue a debit note is when a buyer returns a faulty or unwanted product. Depending on the return policy, the seller may issue a debit note for the full or partial purchase price.
  3. Discounts or Allowances
    A debit note comes into play when a seller grants a discount or allowance to a buyer. This could be due to a bulk purchase, a loyalty program, or other reasons. The seller would issue a debit note for the discount amount.
  4. Faulty Goods
    When a customer gets a faulty product or it doesn’t work as expected, the amount can be refunded via a debit note. Based on the return policy, the seller may provide a debit note for the complete or partial value of the purchase.
  5. Goods Not as Described
    When a customer receives a product different from what was advertised or ordered, the amount can be refunded through a debit note. According to the return policy, the seller may issue a debit note for the entire purchase price or just a part of it.

Debit Notes and Credit Notes in GST

Debit notes in GST

In GST, a debit note is a document issued by a registered person under GST to correct errors or adjustments in a previously issued tax invoice. It essentially increases the taxable value or tax liability of the transaction.

  • It is a supplementary invoice that creates additional tax liability.
  • It is one of the documents used to claim input tax credit by the recipient.
  • The format is not strictly prescribed but should include specific details like the supplier’s and recipient’s information, invoice details, and tax amounts.
  • Both the supplier and recipient must reflect the debit note in their GST returns.

For example, if a supplier mistakenly declared the taxable value as INR 5,00,000 instead of INR 6,00,000, they would issue a debit note for INR 1,00,000 and charge the appropriate tax.

Credit notes in GST

A credit note is a document given by a registered person under GST to correct errors or modifications in a previous tax invoice. It essentially reduces the taxable value or tax liability of the transaction.

  • It is a supplementary invoice that reduces the tax liability.
  • It does not affect the  input tax credit  claimed by the recipient.
  • The format is not strictly prescribed but should include specific details like the supplier’s and recipient’s information, invoice details, and tax amounts.
  • Both the supplier and recipient must reflect the credit note in their GST returns.

For example, if a supplier mistakenly declared the taxable value as INR 10,00,000 instead of INR 9,00,000, they would issue a credit note for INR 1,00,000.
