Credit Note
Credit Note
A credit note is a document issued by a seller to a buyer to reduce the amount owed on a previously issued invoice. It is the opposite of an invoice. Where an invoice says "you owe me this amount," a credit note says "I am reducing what you owe me by this amount." In India, credit notes under GST are governed by Section 34 of the CGST Act 2017. When a GST-registered supplier issues a credit note, it reduces their output tax liability and requires the buyer to reverse the corresponding Input Tax Credit already claimed.

How a credit note works
Here is how a credit note flows between a seller and buyer in a typical Indian business transaction:
-
You raise an original invoice. A Mumbai furniture supplier sends a GST invoice for Rs. 80,000 plus 18% GST to a Delhi buyer for a bulk order of chairs.
-
A problem arises after the invoice. The buyer receives the shipment and finds that 10 chairs out of 50 are damaged. The value of damaged goods is Rs. 16,000 plus Rs. 2,880 GST.
-
The seller issues a credit note. The furniture supplier issues a credit note for Rs. 16,000 plus Rs. 2,880 GST, referencing the original invoice number. The buyer now owes Rs. 64,000 plus GST instead of Rs. 80,000 plus GST.
-
GST liability is adjusted. The supplier reduces their output tax liability by Rs. 2,880 in the month the credit note is issued. This credit note is reported in GSTR-1 under Table 9B.
-
The buyer reverses ITC. The buyer who had already claimed Rs. 14,400 as Input Tax Credit on the original invoice must now reverse Rs. 2,880 of that ITC, since the taxable value has reduced.
Credit note example for Indian businesses
Priya runs a textile business in Surat. In April she sends a GST invoice to a retailer in Chennai for Rs. 1,20,000 plus 12% GST, totalling Rs. 1,34,400.
In May, the retailer returns goods worth Rs. 30,000 due to colour mismatch. Priya issues a credit note as follows:
- Original invoice value: Rs. 1,20,000 plus Rs. 14,400 GST = Rs. 1,34,400
- Credit note value: Rs. 30,000 plus Rs. 3,600 IGST = Rs. 33,600
- Revised amount owed by buyer: Rs. 1,34,400 minus Rs. 33,600 = Rs. 1,00,800
Priya reports this credit note in her GSTR-1 for May. Her output tax liability for May is reduced by Rs. 3,600. The Chennai retailer must reverse Rs. 3,600 of the ITC they had already claimed on the original invoice.
When must you issue a credit note in India
Under Section 34(1) of the CGST Act 2017, a registered supplier must issue a credit note in the following situations:
- Goods are returned by the buyer. The customer sends back goods due to quality issues, wrong product delivered, or damaged items received.
- Services are found deficient. The service delivered was incomplete or did not meet the agreed standard.
- The original invoice overcharged. You accidentally billed a higher amount or applied a higher GST rate than applicable.
- The quantity invoiced was more than what was delivered. You invoiced for 100 units but only delivered 80.
- A post-sale discount is given. A volume discount or trade discount is offered after the original invoice was raised, provided it was agreed upon before or at the time of supply as per Section 15(3) of the CGST Act.
- Cancellation of pending invoices. An outstanding invoice needs to be cancelled and the transaction reversed.
Important note: There is no prescribed time limit for issuing a credit note itself. You can issue it whenever the situation arises. However, the time limit applies to reporting it in your GST returns. A credit note for a supply made in a financial year must be reported by 30th November of the following financial year or the date of filing your annual return for that year, whichever comes first. Missing this window means you cannot reduce your GST liability through a GST credit note. You can only issue a commercial credit note, which does not affect GST.
What a credit note must contain
Under Rule 53(1A) of the CGST Rules 2017, a credit note must include the following details:
- Name, address, and GSTIN of the supplier
- Nature of the document clearly stated as "Credit Note"
- A unique consecutive serial number, not exceeding 16 characters, for the financial year
- Date of issue
- Name, address, and GSTIN of the recipient
- Original tax invoice number and date against which the credit note is issued
- Taxable value of goods or services being reduced
- GST rate, and the amount of CGST, SGST or IGST being reduced
- Signature or digital signature of the supplier

How a credit note affects GST returns
For the seller
The credit note must be reported in GSTR-1 under Table 9B for the month in which it is issued. It is divided into two categories, registered recipients and unregistered recipients, and must be filed separately for each. This reduces the seller's total outward taxable supply for that month and lowers the output GST payable.
For the buyer
Once the seller reports the credit note in GSTR-1, it automatically appears in the buyer's GSTR-2B. The buyer must then reverse the Input Tax Credit proportional to the credit note value. Failure to reverse ITC blocks the seller from reducing their output tax liability on the credit note.
For e-invoicing businesses
If your business is covered under e-invoicing (turnover above Rs. 5 crore), credit notes must also be reported to the Invoice Registration Portal (IRP) for authentication, just like regular tax invoices.
Common credit note mistakes Indian businesses make
-
Missing the reporting deadline. The most common and costly mistake is issuing a credit note in the right month but forgetting to report it in GSTR-1 before 30th November of the following year. After this window closes, the credit note cannot reduce your GST liability. You lose the tax benefit permanently.
-
Not linking to the original invoice. While the new GST system does not always mandate linking a credit note to the original invoice number, including it is strongly recommended. It makes reconciliation simpler and avoids questions during a GST audit.
-
Buyer not reversing ITC. If your buyer does not reverse the ITC linked to your credit note, you cannot reduce your own output tax liability. Coordinate with your buyer to confirm ITC reversal before filing your return.
-
Issuing a credit note for post-sale discounts without a prior agreement. A credit note for a discount is valid only if the discount was agreed upon before or at the time of supply. Arbitrary post-sale discounts reflected through credit notes without a prior written agreement can be rejected during scrutiny.
-
Confusing credit notes with refunds. A credit note does not mean you are returning money to the buyer. It means you are reducing what they owe you. An actual cash refund is a separate transaction. Many small businesses confuse the two and skip issuing credit notes, which causes GST mismatches.
Frequently asked questions
What is a credit note in GST?
A credit note in GST is a document issued by a registered seller to reduce the taxable value or tax charged in a previously issued invoice. It is governed by Section 34 of the CGST Act 2017 and reduces the seller's output tax liability while requiring the buyer to reverse the corresponding Input Tax Credit.
What is the time limit to issue a credit note under GST in India?
There is no legal time limit for issuing the credit note document itself. However, to adjust your GST liability, you must report the credit note in your GSTR-1 by 30th November of the financial year following the year in which the original supply was made, or by the date of filing your annual return for that year, whichever comes first.
Can a buyer issue a credit note?
No. Under GST law, only the supplier or seller can issue a credit note. If the buyer wants to notify the supplier about a short delivery or underbilling, they issue a debit note. The supplier then responds with a credit note if they agree with the buyer's claim.
Does a credit note affect Input Tax Credit?
Yes. When a seller issues a credit note, the buyer must reverse the portion of Input Tax Credit that corresponds to the reduced value. If the buyer does not reverse the ITC, the seller cannot reduce their own output tax liability on that credit note.
Is a credit note the same as a refund?
No. A credit note reduces the amount a buyer owes to the seller on an invoice. It does not automatically mean cash is returned to the buyer. If the buyer has already paid the full invoice amount, the credit note balance can be adjusted against a future invoice or paid out as a cash refund, depending on the agreement between the two parties.
