XYZ is issuing invoice for the supply of goods and charging full GST on the full value of the invoice. At the bottom of the invoice, a remark is given as ‘if payment is received within 7 days, 2% discount will be given’. Can XYZ subsequent to supply issue credit note with GST to the customer for 2% discount if the payment is received within 7 days and reduce his GST liability in that month to the extent of the GST on 2% discount shown in the credit note?
