Southern states in India, including Karnataka, Kerala, and Tamil Nadu, have expressed dissatisfaction over the allocation of tax revenue by the Centre. They claim that their share in central taxes has decreased under the 15th Finance Commission. Finance Minister Nirmala Sitharaman refuted these claims, stating that the Centre has no discretion in allocating funds to states, and it is done based on the recommendations of the constitutional body, the Finance Commission. The allocation formula is a contentious issue, with concerns raised about the weightage given to income distance and population.
