In a regulatory filing submitted under Regulation 30 of SEBI (Listing Obligations and Disclosure Requirements), the airline said the order was received on 29 December 2025 and pertains to an assessment under Section 74 of the Central Goods and Services Tax Act, 2017, covering the period from FY 2018-19 to FY 2022-23.
According to the disclosure, the tax authority has raised the demand—including interest and penalty—on compensation received from a foreign supplier and by disallowing certain input tax credits claimed by the company.
InterGlobe Aviation said the order is “erroneous and not in accordance with law”, adding that it has taken expert legal advice and intends to challenge the demand through appropriate appellate mechanisms. The company noted that it is already engaged in appellate proceedings before the Commissioner (Appeals) in a related matter concerning an earlier financial year.
Despite the size of the tax demand, IndiGo said it does not expect any material impact on its financial position, operations, or cash flows, and will pursue legal remedies as available under the law.
The disclosure comes amid heightened tax scrutiny faced by large corporates, including airlines, over GST treatment of cross-border transactions and compensation arrangements. IndiGo has, in recent months, reported other tax-related notices, which it has consistently said are being contested.
