We are auditing purchase in Utranchal, we have seen that most of the purchase are from outside Uttranchal, and each invoice from other state come with Form-16 of VAT issued by the purchaser from Uttranchal.
I want to know What is form 16 and why it is used. So far as I knew that in case of purchasing goods from other state the purchase have to issue Form-C to procure goods with lower rate of CST.
So why Form 16 is used here instead of Form-C of CST ?
