Financial credit notes would not adjust the amount of GST involved in the original tax invoice issued at the time of supply of goods and/ or services. Accordingly, the transaction value of supply of goods and/ or services shall stand reduced although tax paid thereon remains the same. This may result in higher amount of GST being paid considering the adjusted value of original supply. Since, the value of financial credit notes is to be reduced from the financial statements and not the GST Annual return, it is required to be adjusted in Sl. No. 5J of FORM GSTR-9C.
