I am an automobile dealer. Recently the excise duty on passanger car has been reduced to 8 % from 12 %. Our company sent us a new price list reflecting the excise reduction. Now my question is 1. Can our company claim for excise refund on our behalf on the stock that I was having in my dealership which I have already purchased from the company at old excise rate. 2. Can our company also claim for CST refund because of the excise reduction.
