Debit Note, Credit Note & Revised Invoice under GST

Updated on July 07, 2025 01:49:43 PM

In the Goods and Services Tax (GST) system, proper invoicing is crucial for tax compliance and accounting. But in actual business practices, invoices can be erroneous or altered due to price modifications, quantity adjustments, or return of products. For such purposes, the GST legislation allows the utilization of debit notes, credit notes, and amended invoices.

A debit note is made by the seller when the taxable value or tax levied in the original invoice is lower than it should have been. It enables the seller to raise the tax liability accordingly. Conversely, a credit note is made when the original invoice has charged the customer more than they should have been charged, or when goods are returned or services are not completely received. This decreases the seller's tax liability.

A corrected invoice is employed when a normal tax invoice was issued before the supplier was granted their GST registration. After registration, the supplier has to issue corrected invoices for such transactions.

Such documents facilitate accurate adjustment of tax liabilities and assist in maintaining transparency and compliance under the GST system. Knowledge of their proper use is crucial for businesses to escape penalties and ensure hassle-free filing of GST returns.

What is a Debit Note under GST?

A Debit Note under GST is a document sent by a registered supplier to the recipient when the original tax invoice has undercharged the tax value or tax amount. It is a formal way of raising the value of the original invoice, thus adjusting the tax liability accordingly.

For instance, if a seller finds, after raising an invoice, that the cost of goods was computed lower than the agreed amount, or that tax should have been charged more, the seller raises a debit note to rectify the difference. This keeps both parties' records correct, and the seller pays the extra amount of tax while the buyer can claim the right input tax credit.

A debit note should carry certain information, such as the original invoice date and number, debit note number, description of goods/services, amount of variation, and GST rate. This information should also be reflected in the supplier's GSTR-1 return for the month in question.

What is a Credit Note under GST?

A Credit Note under GST is a lawful document given by a registered vendor where the original invoice value for goods or services is more than the actual payment amount. It is generally released where goods are returned by the buyer, the discount is given after the invoice is sent, services are not entirely delivered, or there has been an overpayment in the initial bill. The main reason for issuing a credit note is to decrease the taxable value and, consequently, the tax liability.

The credit note should include the reference of the initial invoice, issue date, purpose of issuance, the adjusted taxable value, and GST information. It should be filed in the GSTR-1 return of the month it is issued, and the tax liability adjustment is shown in the seller's return of GST. Credit notes encourage precision and compliance in GST invoicing and assist businesses in having transparent records and preventing tax disputes.

What is a Revised Invoice under GST?

A Revised Invoice under GST is a document that a registered taxpayer issues to substitute or rectify an already issued invoice that was issued before the registration for GST. When a business registers for GST and is allotted its GSTIN (Goods and Services Tax Identification Number), it is statutorily obligated to issue revised invoices for all taxable supplies made between the date of registration coming into effect and the date of issuance of the GST registration certificate.

A revised invoice should specifically state that it is a revised invoice of the original document. It should include the serial number and date of the original invoice, as well as the correct GSTIN, invoice number, description of goods or services, value, tax rate, and amount. The revised invoices should be issued within one month of the date of issue of the GST registration certificate.

GST Implications of Debit and Credit Notes

Under the GST regime, debit and credit notes carry definite implications regarding tax liability and input tax credit (ITC) for the recipient as well as the supplier. These notes are crucial documents to make the value of a tax invoice previously issued without it being cancelled.

When a debit note is raised, it reflects an addition to the taxable value or GST amount. It means that the supplier must add their output tax liability and remit the extra GST in their monthly return (GSTR-1 and GSTR-3B). The buyer can claim a greater ITC on the updated value, however.

Both debit and credit notes should be accounted for in the GSTR-1 return by the supplier, and their impact is shown in the GSTR-2A/2B of the recipient. These need to be made within a specific time limit, particularly for credit notes, which need to be made on or before 30th November of the subsequent financial year or before the annual return is filed, whichever is earlier.

Time Limits for Issuing Credit and Debit Notes

Under the GST law, there is a specific period for issuing credit and debit notes, particularly to provide a timely adjustment of tax liability. These time frames ensure transparency and prevent abuse of tax benefits.

For Credit Notes, the period is specified. A supplier is required to give a credit note on or before 30th November of the subsequent financial year in which the initial supply was made, or before filing the annual return, whichever is earlier. For instance, if a supply was done in July 2024, the credit note should be given by 30th November 2025, or before the filing of the FY 2024-25 annual return, whichever occurs first. Once this period has elapsed, credit notes can still be released, but the tax adjustment cannot be made in GST returns.

For Debit Notes, there has been a relaxation in the rules. According to recent amendments, there is no particular time limit for issuing a debit note. It can be issued and lodged in the GST return of any future period without regard to the financial year of the original invoice. This makes suppliers more flexible in raising the amount of the original invoice and paying any difference in tax.
