Understanding Debit & Credit Notes under GST: Revising an Invoice

A key reason why GST in India enhances tax compliance and reduces the circulation of black money is through the standardization and matching of invoices. Under GST provisions, all B2B invoices must be uploaded on the GST common portal during the filing of GST returns. The system auto-populates invoice details to the buyer or recipient during the filing of returns of inward supplies or GSTR-2, thus eliminating chances of foul play in B2B invoices. However, in cases that require genuine amendments, a supplier can issue a debit or credit note to revise an invoice. Let's delve deeper into the role of debit and credit notes under GST.

What is a Debit Note?

A debit note is a document sent to the seller to inform them that a debit has been made in the seller's account. During or after a sale, if the consumer finds the goods unsatisfactory and returns them, a debit note is produced. It also serves as a reminder to both the seller and the buyer about the debit made to the buyer's account. Additionally, a seller might issue a debit note if they accidentally undercharged the buyer or provided extra items on the same invoice. Under GST, a debit note must be issued under specific criteria:

  • Supply of goods and/or services was made to the respective person.
  • A tax invoice for the supply was issued.
  • The taxable value and/or tax charged in the tax invoice is less than the taxable value or tax payable.
  • The adjustment of tax liability is necessary.

What is a Credit Note?

A credit note is a document usually issued by a seller to a buyer, indicating that a credit has been applied to the buyer's account. For instance, in a situation where a seller sold 10,000 units and 1,000 were defective, the seller can issue a credit note, making the buyer liable for payment only for 9,000 units. Conversely, a buyer might issue a credit note if they were undercharged or received more items than billed. Under GST, a credit note is issued when:

  • Supply of goods and/or services was made to the respective person.
  • A tax invoice for the supply was issued.
  • The taxable value or tax charged exceeds the amount payable, or the recipient returns faulty goods.

Revising Invoices in B2B Transactions

The issuance of a debit or credit note affects the previously issued invoice, necessitating its revision. In transactions where both parties have GSTIN or when the invoice value exceeds Rs.2.5 lakhs, the revised invoice must include specific details along with the prominently displayed term "Revised Invoice":

  • The term “Revised Invoice” prominently indicated;
  • Name, address, and GSTIN of the supplier;
  • Nature of the document;
  • A consecutive serial number, up to 16 characters, unique for a financial year;
  • Date of issue;
  • Name, address, and GSTIN or UIN of the recipient;
  • Recipient's name and address of delivery, along with the State name and code for un-registered recipients;
  • Serial number and date of the corresponding tax invoice or bill of supply;
  • Value and tax details of the supply;
  • Supplier or authorized representative’s signature or digital signature.

Revising Invoices in B2C Transactions

For B2C transactions, or when the transaction is under Rs.2.5 lakhs and the individual is without a GSTIN, a consolidated revised tax invoice can be issued. In inter-state supplies not exceeding Rs.5 lakhs, suppliers can issue a consolidated revised invoice for recipients in a state.
