Shares of aviation companies, including InterGlobe Aviation (IndiGo) and SpiceJet, could see action as the government’s 55th GST Council meeting considers a landmark move: bringing aviation turbine fuel (ATF) under the GST framework. The potential inclusion of ATF in GST has long been a key demand from the aviation industry, offering the promise of reduced operational costs and improved efficiency. Currently, ATF—a clear and highly flammable petroleum distillate used for aircraft refueling—is subject to varied state-level taxes, often at prohibitive rates. If ATF is brought under GST, it could streamline tax rates across the country, providing relief to airlines and boosting their financial performance. The GST Council, chaired by Union Finance Minister Nirmala Sitharaman and attended by state representatives, will deliberate on this issue in Jaisalmer on December 21. With jet fuel prices already pressuring margins, a uniform GST rate could be a game-changer for the sector.
