BBC News - Eighteen Aviation at Stansted owes council £1.12m tax
Eighteen Aviation Limited, trading as Aero Toy Store, keeps aircraft at Stansted Airport and has defaulted on its 2012-13 business rates liability.
Uttlesford District Council took legal proceedings against the firm but was told recovery was "unlikely".
Eighteen Aviation said it was aware of the decision, was working with advisers and was in touch with the council.
The aviation firm is the second largest business ratepayer in the district and occupies the 18-acre Diamond Hangar at Stansted Airport.
Aero Toy Store is based at Fort Lauderdale in Florida and describes itself on a website as "a full service global dealer in transcontinental aircraft".
