Also, in order to safeguard their revenues, states did not agree to include several items under GST. Petroleum products, for one, are out of this. While this can lead to a Rs 20,000-25,000 crore tax loss to the sector—as input credits will not be available—states were not willing to include petroleum products as they collect a lot of taxes from here. So, if GST starts delivering, perhaps the GST Council can think of including this under GST. Ideally, once GST takes off, the Council should work on a schedule, or milestones, for expanding the scope of GST as well as for reducing the revenue neutral rate.
