The GST Council is meeting in New Delhi to overhaul GST slabs by removing the 12% and 28% rates.
A dual GST structure of 5% and 18% has been proposed, which is expected to cost around ₹80,000 crore annually to treasury.
The rate rationalisation could lower GST on about 175 products, from food items to automobiles and electronics.
The government may revive the National Anti-Profiteering Authority (NAA) for a limited period.
