The implementation of the goods and services tax and subsequent changes in the indirect taxation regime have benefitted traders and manufacturers by significantly reducing the inter-state transaction costs and the incidence of multiple indirect taxation, PHDCCI President Pradeep Multani said on Friday. "There has been substantial shifting of goods from high tax slabs to lower ones after the implementation of GST. The number of items under the highest tax slab of 28 per cent has come down to only three per cent in January 2022 from 17 per cent at the time of implementation of GST," said the president of the PHD Chamber of Commerce and Industry (PHDCCI). Many items have been shifted to 18 per cent or less than 18 per cent tax slabs from 28 per cent during the past five years, he said. GST tax slab of 18 per cent contains around 44 per cent of goods under its ambit as of now as compared with around 33 per cent at the time of implementation of GST, Multani added in the statement by the chamber.
