Mastercard Network as Permanent Establishment Called Very Dangerous by Delhi High Court in Tax Dispute

The Delhi High Court has orally raised serious concerns over the Authority for Advance Rulings’ (AAR) finding that a foreign enterprise’s network and related infrastructure could constitute a permanent establishment (PE) in India, warning that such an interpretation poses a “very dangerous proposition” with potential for misuse across jurisdictions. A Division Bench comprising Justice Dinesh Mehta and Justice Aditi Choudhary made the observation while hearing Mastercard Asia Pacific Pte. Ltd. ’s challenge to the AAR’s 2018 ruling, which held that the Singapore-based payment network had multiple PEs in India under the India-Singapore Double Taxation Avoidance Agreement (DTAA) .

The case, which has been pending for nearly eight years, concerns the tax treatment of Mastercard’s operations in India. The AAR had ruled that Mastercard Interface Processors (MIPs) installed at customer banks’ premises, as well as the broader Mastercard network—including leased lines, fibre-optic cables, and transmission towers—constituted fixed-place PEs under Article 5 of the DTAA . Additionally, the AAR found that Bank of India ’s premises, used for domestic settlement activities, also amounted to a PE. Mastercard has contested these findings, arguing that its Indian presence is limited to preparatory and auxiliary functions.

During the hearing on September 22 , the court expressed strong reservations about the AAR’s approach. “AAR’s view that towers and network itself constitute a PE is a very dangerous proposition ... it can be misused anywhere,” the bench observed. The court also flagged the broader international implications, stating that affirming such a finding could give “a very bad picture of the country” and would have significant consequences for business and the economy.

The Revenue , defending the AAR’s ruling, argued that the MIPs perform critical functions beyond mere communication. They carry out preliminary verification and validation—including PIN processing, card-code validation, and name and address verification—which are integral to transaction authorisation. The Revenue submitted that without this initial processing through the MIPs, authorisation would not occur, and therefore the Indian operations cannot be characterised as merely preparatory or auxiliary.

The court, while critical of the AAR’s broad interpretation, indicated that a more nuanced assessment might be appropriate. It suggested that the network could be examined together with the MIPs and other elements of Mastercard’s operations as part of a holistic assessment . This leaves open the possibility that a combination of factors—rather than the network alone—could lead to a PE finding.

The Revenue is expected to continue its arguments in the second week of October , when the next hearing is scheduled. The outcome of this case will be closely watched by the international tax community, particularly for its potential impact on foreign enterprises that rely on network infrastructure and data processing facilities in India.

Background of the Dispute

Mastercard, a global payment technology company, facilitates electronic payment transactions between issuer and acquirer banks through its proprietary network. In India, Mastercard Interface Processors are installed at the premises of customer banks. These processors perform initial verification steps before transmitting transaction data to Mastercard’s global systems for authorisation and settlement. The AAR concluded that the MIPs constitute a fixed-place PE because they are located at a fixed location (the banks’ premises) and perform functions that are essential to Mastercard’s core business.

The AAR also held that the Mastercard Network in India—comprising MIPs, transmission towers, leased lines, fibre-optic cables, nodes, internet connectivity, and software applications like Master Connect and MasterCard File Express—constitutes a separate fixed-place PE . Furthermore, it found that domestic settlement activities, involving the movement of funds between Indian banks through Bank of India , created another PE at Bank of India ’s premises.

Mastercard challenged these findings, arguing that the MIPs and network are merely communication tools and that the core activities of authorisation and settlement occur outside India. The company relied on the preparatory or auxiliary exclusion under Article 5(4) of the DTAA , which provides that a fixed place of business used solely for activities of a preparatory or auxiliary character shall not be deemed a PE.

Key Developments in the Hearing

During the hearing, the court’s oral observations signalled a clear discomfort with the AAR’s expansive definition of PE. The bench noted that if every network or tower were treated as a PE, it could lead to absurd results and be exploited by tax authorities in other countries. The court emphasised the need for a balanced interpretation that respects the object of tax treaties while preventing abuse.

The Revenue , on the other hand, relied on the AAR’s detailed analysis of the functions performed in India. It argued that the MIPs are not passive communication devices but active processors that perform essential validation steps. The Revenue contended that the Indian activities are integral to Mastercard’s business model and cannot be dismissed as preparatory or auxiliary. It further submitted that the characterisation of the Indian operations should be assessed in the context of Mastercard’s overall business, not in isolation.

The court’s indication that a holistic assessment might be appropriate suggests that it may adopt a middle ground—neither rejecting the PE finding outright nor accepting the AAR’s broad interpretation. This could involve considering the cumulative presence of MIPs, network infrastructure, and settlement activities to determine whether Mastercard has a sufficient physical presence in India to constitute a PE.

Legal Analysis of Permanent Establishment under the DTAA

The concept of permanent establishment is central to the allocation of taxing rights between treaty countries. Under Article 5(1) of the India-Singapore DTAA , a PE is a fixed place of business through which the business of an enterprise is wholly or partly carried on. The term includes places of management, branches, offices, factories, workshops, and mines, among others. However, Article 5(4) excludes specific activities that are considered preparatory or auxiliary in nature.

The key issue in this case is whether Mastercard’s MIPs and network infrastructure meet the threshold of a fixed place of business . The AAR’s reasoning that the network itself—including intangible components like software and leased lines—constitutes a physical location is controversial. The Delhi High Court ’s observation that this is a “dangerous proposition” highlights the potential for tax authorities to assert PE status over any enterprise with digital infrastructure in a country.

The preparatory or auxiliary exclusion is also central. The Revenue argues that the MIPs perform core functions, not merely preparatory ones. However, the court may need to determine whether the activities are genuinely auxiliary to the main business of transaction processing, which occurs primarily outside India. International jurisprudence on this point varies, and the outcome in this case could influence future disputes involving digital payment networks.

Implications for Tax Practice and the Digital Economy

The Delhi High Court ’s eventual decision will have significant implications for multinational enterprises operating in India, particularly those in the technology and financial services sectors. If the court upholds the AAR’s finding that network infrastructure alone can create a PE, it could lead to increased tax exposure for foreign companies that rely on data centres, servers, and communication networks in India. Conversely, a ruling in favour of Mastercard could provide clarity that mere network presence does not establish a PE without more substantial physical operations.

The case also has broader implications for the international tax framework, as countries increasingly grapple with the taxation of the digital economy. The Organisation for Economic Co-operation and Development ( OECD ) has been working on a multilateral solution, but national courts continue to interpret existing treaty provisions in varying ways. A clear ruling from the Delhi High Court could contribute to the development of consistent jurisprudence on the treatment of digital infrastructure as PE.

Tax practitioners and multinational enterprises will be watching the October hearing closely. The court’s willingness to consider the wider economic consequences and the risk of misuse across jurisdictions suggests a cautious approach that may limit the AAR’s expansive interpretation. However, the Revenue ’s strong reliance on the functional importance of the MIPs means that the outcome is far from certain.

Conclusion

The Delhi High Court ’s oral observations in the Mastercard case have already sent ripples through the international tax community. By describing the AAR’s view of network-as-PE as “very dangerous,” the court has signalled a potential shift away from overly broad interpretations of permanent establishment. Yet the court also left the door open for a holistic assessment that could still find a PE based on the cumulative activities of Mastercard in India.

The next hearing, expected in the second week of October , will see the Revenue complete its arguments. The final judgment will be eagerly awaited by tax lawyers, multinational corporations, and treaty negotiators alike, as it will shape the landscape for taxing digital infrastructure in India for years to come.
