GST Row Deepens As Mamata Questions Amit Mitra

West Bengal chief minister Mamata Banerjee’s latest attack on GST has exposed visible strain between her and the Chief Financial Adviser and former Finance Minister Dr Amit Mitra. She has questioned his role in backing the indirect tax regime and blamed the Centre for substantial losses to the state. She accused the Centre of collecting GST on behalf of states while withholding their legitimate share, alleging West Bengal has been deprived of Rs 20,000 crore. In an unusually direct reference to her adviser, Mamata questioned Dr Mitra’s support for GST during its formulation and rollout, when he chaired the drafting committee and advocated a uniform tax structure as economically beneficial. She said his position must now be explained in light of continued deductions from GST revenues and the scale of losses claimed by the state. Dr Mitra has pointed to parliamentary statements in which the Centre acknowledged GST fraud amounting to Rs 2 lakh crore. Mamata has countered that while the figure has been officially stated, there is no credible evidence establishing the actual scale of fraud, raising doubts over whether GST has resulted in net gains or losses for states. The remarks come weeks after Mamata publicly admitted that her government erred in accepting GST. She also said that during the GST rollout, Dr Mitra explained the concept of a uniform tax structure to her, an explanation she has since described as misguided, adding that it was based on this understanding that the TMC became the first party to support GST. The public questioning of Mitra highlights growing tensions within the state’s economic leadership amid intensifying Centre-state fiscal confrontations.
