Delhi, Dec 12: With the IndiGo airlines crisis deepening day by day, the carrier now faces a new challenge.

It has now been issued a tax penalty notice amounting to ₹58.75 crore for the financial year 2020–21.

The notice was served by the Additional Commissioner of CGST, Delhi South Commissionerate, as stated by the airline in a regulatory filing on Friday.

As per InterGlobe Aviation Ltd., the parent company of IndiGo, the order—received on December 11—demands GST payment along with associated penalties.

During unsolved crisis and disruption of flights, huge tax penalty on the flight operator has shook the organisation’s backbone.

Fixing responsibility over the frequent flight disruptions, on four Flight Operation Inspectors(FOIs) the Directorate General of Civil Aviation (DGCA) has terminated four officials who were tasked with overseeing IndiGo’s safety and operational welbeings.

To address the situation, two dedicated DGCA oversight teams have been deployed to IndiGo’s Gurugram headquarters to conduct daily monitoring.

The combined measures reflect the Centre’s escalating intervention as IndiGo faces severe backlash over its handling of the disruptions.
