Our company purchase car in the month of Oct'2017, here dealer offer a discount in the perform of Rs. 38000/- but in invoice he show Rs. 29,687.50, dealer saying that "we deducted GST @28% from your Discount figure. and he is not showing Rs.8,312.50 in Invoice.
I want to know that the dealer can deduct the GST in discount, if yes then he has to show in Invoice.
