The GoM on GST rate rationalisation on Saturday deferred submission of its report, which suggested rate rationalisation in 148 items, to the GST Council, the panel's convenor and Bihar Deputy Chief Minister Samrat Chaudhary said. "Will submit the Group of Ministers (GoM) report on rate rationalisation in next meeting of the Council," Chaudhary told reporters here. The GoM had earlier this month arrived at a broad consensus to rejig tax rates on about 148 items, including levying a higher 35 per cent tax on sin goods, like aerated beverages and tobacco products, as compared to 28 per cent at present. It was widely expected that the GoM would submit its report to the GST Council meeting on Saturday. Currently, GST is a four-tier tax structure with slabs at 5, 12, 18 and 28 per cent. Luxury and demerit goods are taxed at highest bracket of 28 per cent, while packed food and essential items are at the lowest 5 per cent slab. The GoM had also decided to propose rationalising tax rates
