Q: Sir if supplier provides discount based on achievement of my sales target than I have to raise invoice with GST for that?
If the discount is established beforehand through agreement, specifically linked to relevant invoices & corresponding ITC reversed, ) then GST is levied excluding such discount value. Refer Section 15(3) of CGST Act.
