The Union government has estimated the monthly GST collection at over Rs 1.2 lakh crore, said CBIC chairman. He added that there’s a need for the GST council to deliberate bringing petroleum products under the ambit of GST. “The major concern states have had in the past is the adverse impact on their revenue,” he told. “All states levy VAT on sale of petroleum products, which are not under GST. This apprehension was strong in the initial phases of GST, because the revenue string that people expected from GST did not materialize, and then the picture got complicated because of Covid.”
