The dealer pays VAT by deducting the tax paid on purchases (input tax) from his tax collected on sales (output tax). Hence, VAT = Output Tax – Input Tax. For example: A dealer pays Rs.10.00 @ 10% on his purchase price of goods valued Rs.100.00. He sells the goods at Rs.150.00 and collects tax amounting to Rs.15.00 (@ 10%). He will pay Rs.5.00 (Rs.15.00- Rs.10.00) as he has already paid Rs.10.00 to his seller while purchasing those goods.
