What is a credit note?
A document sent from one party to another encapsulates the fact that the sender credits the other party’s account in his books. If there is any change in the taxable value of the supplied goods, then the supplier may issue a credit note which cites the particulars.
One of the major differences between credit and debit notes is that a debit note diminishes a buyer’s liability. A credit note is a seller's response to the buyer’s debit note. Credit notes can be used as a refund substitute because they enable a customer to buy products later without paying for them.
Reasons to issue a credit note
In line with Section 34(1) of the CGST Act, the supplier may provide a credit note when a tax invoice is created and needs to be modified to lower the tax burden indicated on it. The following are some of the most likely causes for the seller to provide a credit note:
-
Due to buyer returns due to quality problems, service rejection, or receipt of damaged items.
-
Higher charges were incorrectly collected from the buyer, or the buyer paid more than the invoiced value.
-
Give the buyer a post-sale discount.
-
The amount received by the customer is less than the amount stated on the tax invoice.
-
Canceling any outstanding invoice payments.
-
Any other comparable reason.
All credit note details issued during the month must be submitted in GSTR-1. The previously generated credit note can be amended, and the changes should be reported in the monthly GSTR-1. Related information will be automatically reflected in the recipient's GSTR-2B and GSTR-2A.
It enables a supplier to amend previously issued tax invoices. It smoothens the process of reducing tax liability without the time-consuming process of claiming refunds. In addition, all debit and credit notes issued according to Section 34 of the CGST Act must be reported to the IRP for e-invoicing.
