The Goods and Services Tax (GST) department has levied a tax demand of ₹124.65 crore against SpiceJet due to the airline's failure to file GST returns for several months. The demand arises from consistent irregularities in filing, with specific amounts assessed for each month: ₹44.44 crore for November, ₹43.79 crore for December, ₹12.19 crore for January, ₹12.10 crore for February, and ₹12.12 crore for March. In conjunction with this demand, the GST department has issued a show-cause notice on May 25, 2026, threatening to cancel SpiceJet's GST registration if the airline does not rectify its filing issues. Despite the severity of the situation, SpiceJet officials have not been reachable for comment. The GST department has emphasized that if SpiceJet fails to file its pending returns and comply with statutory obligations, it will face further actions as per GST regulations. This situation highlights ongoing challenges for the airline, which has been struggling financially in recent times.
