Experts said going forward as the revenues stabilise, the Council may look at further rationalisation of the 28 per cent slab, to restrict the highest tax slab to super luxury and sin goods.
Deloitte India Partner M S Mani said it would be logical to expect that once the GST collections after the recent reductions stabilise, the remaining items such as televisions of all sizes, dishwashers, digital cameras, air conditioners could be considered for an 18 per cent rate.
"It would be ideal if only demerit goods are retained in the 28 per cent slab so that a gradual movement towards having fewer GST slabs can be initiated," Mani said.
After the latest rounds of rate cuts by the GST Council on July 21, only 35 items are left in the 28 per cent tax slab, an official said.
The Council brought down tax rates to 18 per cent from 28 per cent on 15 items, including vacuum cleaners, washing maching, 68 cm (27 inch) TV, fridge, laundry machines, paints and varnishes.
"The rate cuts would lead to a revenue loss of about Rs 60 billion," the official said.
The official, however, said that the revenue loss would be only notional as increased consumption and compliance would lead to more revenues to the exchequer.
EY Partner Abhishek Jain said: "The reduction of GST rates from 28 per cent to 18 per cent shows that directionally, the Government seems to be clear that the 28 per cent rate should be restricted to super luxury and sin goods".
