One of My Client's Head Office is in Mumbai(1st Point of Sale). They Have transferred the goods to Chennai Branch office. Stock Transfer value is about (Example)Rs. 1,00,000. Chennai Branch Issue Form F for Rs.1,00,000. But they have sale the goods for 80,000 due to discount issued to the customer. Now chennai office consultant said that we have to pay tax for the difference amount of Rs.20,000/- because we got Form F for 1,00,000/-. the Discount amount will consider evasion of Tax. Was it Correct . Kindly Advice.
