Supreme Court Dismisses GST Department's Review, Upholds ITC on Telecom Towers for Airtel

The Supreme Court on August 19, 2026 , dismissed the Goods and Services Tax (GST) Department 's review petitions against Bharti Airtel , Indus Towers , and Elevar Digitel Infrastructure , firmly shutting the door on the Revenue's attempt to deny input tax credit (ITC) on telecom towers. A bench of Justices Vikram Nath and Prasanna B. Varale found " no error apparent on the face of the record " in the court's earlier order that had upheld the Delhi High Court 's ruling in favor of the telecom companies.

A Long-Running Dispute Over Tower Infrastructure

The core of the dispute revolved around the interpretation of Section 17(5)(d) of the Central Goods and Services Tax Act, 2017, which restricts ITC on goods or services used for the "construction of immovable property." The Revenue argued that telecom towers, being affixed to land or rooftops with concrete foundations, constituted immovable property and thus fell outside the scope of eligible ITC. This interpretation threatened to impose significant costs on telecom operators, for whom tower deployment represents a major capital expenditure.

The telecom companies, led by Bharti Airtel, countered that towers are essentially movable equipment that can be dismantled and relocated. They asserted that the concrete foundation merely provides stability and does not change the fundamental character of the tower as plant and machinery. They relied heavily on the Supreme Court's own precedent in Bharti Airtel Ltd. v. Commissioner of Central Excise, Pune , which had addressed a similar issue under the service tax regime.

The Delhi High Court's Rationale

The Delhi High Court , in its December 12, 2024 judgment, had sided with the telecom companies in a detailed ruling. It observed that the specific exclusion of telecommunication towers from the term " plant and machinery " in the Explanation to Section 17(5) did not automatically make them immovable property . The court held that a telecom tower must independently qualify as immovable property for the restriction to apply. "The specific exclusion of telecommunication towers from the scope of the phrase ' plant and machinery ' would not lead one to conclude that the statute contemplates or envisages telecommunication towers to be immovable property ," the High Court had stated. It then quashed the denial of ITC and the underlying show cause notices .

The Supreme Court's Final Word

The GST Department had challenged the High Court's ruling directly before the Supreme Court , but a bench dismissed the special leave petitions on August 8, 2025 . Undeterred, the Department filed the present review petitions , arguing that the court had overlooked critical errors. On August 19, 2026 , the Supreme Court reviewed the grounds but remained unpersuaded. "We have carefully considered the review petition(s) as well as the grounds set out therein," the bench noted. "Having examined the impugned order in light of the grounds raised, we are of the considered opinion that there is no error apparent on the face of the record , in the order impugned, that would justify its reconsideration."

The court condoned the delay in filing the review but dismissed the petitions as meritless. All pending applications were disposed of.

Implications for the Telecom Sector

The dismissal of the review brings near-finality to a question that had created significant uncertainty for the telecom industry. Indus Towers , in its annual report for 2025–26, had already referenced the August 2025 Supreme Court order favorably, noting that it "strengthens the economics and tax efficiency of the telecom tower business model." With the review dismissed, telecom companies can now claim ITC on towers without the threat of retroactive denial, improving returns on new deployments and potentially enabling recovery of previously disputed credits.

The ruling also reaffirms a key principle: the classification of an asset as immovable property for GST purposes depends on its inherent nature, not merely on the fact of attachment to the earth. Telecom towers, which are designed to be shifted, remain eligible for input tax credit as plant and machinery.
