Secondary discounts are generally offered after the sale by way of reducing the price product. For Eg. Mr A supplies 10000 packets of biscuits to Mr B at rs 10/- per packets. Afterwards Mr A revalue it at 9/ per packet . Subsequently Mr. A issue the note to Mr B for Rs.1 per packets. In GST such discount are not included in value of supply as it does not satisfied the condition laid in clause (b) of sub section (3) of Section 15 of CGST Act .
