International taxation in India is increasingly determined not merely by the wording of the Income-tax Act, but by the interaction between Double Taxation Avoidance Agreements (DTAAs), permanent establishment rules, residential status, source rules and judicial interpretation<\/strong>.<\/p>\n\n\n\n Recent decisions of the Supreme Court, High Courts and Income Tax Appellate Tribunal have addressed several recurring questions:<\/p>\n\n\n\n These questions have become especially important after the transition to the Income-tax Act, 2025 from 1 April 2026<\/strong>.<\/p>\n\n\n\n Taxpayers dealing with overseas payments should therefore examine not only domestic law but also the applicable DTAA before determining withholding tax or filing Form 145 and Form 146 for foreign remittance<\/a>.<\/p>\n\n\n\n Delhi High Court \u2013 [2025] 181 taxmann.com 874<\/strong><\/p>\n\n\n\n The first case concerns a US company providing BPO-related services to customers outside India.<\/p>\n\n\n\n The foreign company had entered into a services agreement with an Indian group company. The Indian entity provided services relating to the foreign company’s customers and raised invoices on the US company. The core question was whether these arrangements resulted in a Permanent Establishment of the US enterprise in India under Article 5 of the India-USA DTAA<\/strong>.<\/p>\n\n\n\n Article 5 of the India-USA DTAA recognises a fixed-place PE and also contains a service-PE provision where services are furnished in India through employees or other personnel subject to the prescribed conditions.<\/p>\n\n\n\n The broader principle is important:<\/p>\n\n\n\n The actual functions, control, place at the foreign enterprise’s disposal and treaty conditions must be examined.<\/p>\n\n\n\n This distinction is highly relevant for multinational companies outsourcing technology, BPO, accounting, consulting or back-office services to India.<\/p>\n\n\n\n For an overview of the treaty provisions themselves, readers may also refer to our detailed guide on the India-USA DTAA<\/a>.<\/p>\n\n\n\n Delhi ITAT \u2013 [2025] 179 taxmann.com 664<\/strong><\/p>\n\n\n\n An Indian company made payments to a Norwegian resident under a works contract for replacement of defective parts of a ship.<\/p>\n\n\n\n The Norwegian enterprise’s employees remained in India for only 29 days<\/strong>.<\/p>\n\n\n\n Under Article 5 of the India-Norway DTAA, a construction, assembly or installation project constitutes a PE only where the prescribed duration threshold is satisfied.<\/p>\n\n\n\n This illustrates an important international-tax principle:<\/p>\n\n\n\n However, absence of a PE does not always end the analysis.<\/p>\n\n\n\n The character of the payment must still be considered under the relevant DTAA provisions dealing with fees for technical services, business profits or other income<\/strong>.<\/p>\n\n\n\n That distinction is particularly important when determining tax deduction on payments to overseas contractors.<\/p>\n\n\n\n Delhi ITAT \u2013 [2025] 180 taxmann.com 135<\/strong><\/p>\n\n\n\n A German bank advanced an External Commercial Borrowing to an Indian borrower. The ECB was guaranteed by Hermes-Deckung, Germany.<\/p>\n\n\n\n The Indian borrower made several payments, including:<\/p>\n\n\n\n The issue was whether these amounts should receive the treatment available to interest under Article 11 of the India-Germany DTAA<\/strong>, or whether some payments constituted fees for technical or managerial services.<\/p>\n\n\n\n The practical lesson is important for foreign borrowing transactions:<\/p>\n\n\n\n The legal character of processing fees, commitment charges, guarantee charges and advisory fees must be separately examined.<\/p>\n\n\n\n This becomes directly relevant while determining withholding tax before an overseas remittance.<\/p>\n\n\n\n Businesses remitting interest, professional fees, royalty or technical-service payments should undertake a DTAA analysis before completing Form 145 and Form 146 filing<\/a>.<\/p>\n\n\n\n Delhi ITAT<\/strong><\/p>\n\n\n\n The presentation discusses a Japanese enterprise which had supplied telecom equipment to an Indian customer.<\/p>\n\n\n\n The customer defaulted on payment, resulting in arbitration. Fujitsu succeeded in arbitration and received compensation relating to the unpaid business dues.<\/p>\n\n\n\n The question was whether the arbitral compensation represented:<\/p>\n\n\n\n The underlying principle is particularly useful:<\/p>\n\n\n\n A payment does not automatically become an isolated \u201cwindfall\u201d merely because it is received pursuant to arbitration.<\/p>\n\n\n\n The official ITAT record confirms the Fujitsu international-tax litigation. (Income Tax Appellate Tribunal<\/a>)<\/p>\n\n\n\n The same Fujitsu litigation also considered interest earned on amounts deposited with an Indian bank during the arbitration process.<\/p>\n\n\n\n The case study asks whether such interest fell within Article 11 of the India-Japan DTAA<\/strong>.<\/p>\n\n\n\n This highlights an important principle:<\/p>\n\n\n\n For businesses and foreign enterprises, this can affect:<\/p>\n\n\n\n Delhi ITAT \u2013 [2026] 183 taxmann.com 726<\/strong><\/p>\n\n\n\n A US enterprise engaged in turnkey projects appointed an independent consultant in India.<\/p>\n\n\n\n The consultant’s role was primarily to identify an Indian project partner which could supply and erect indigenous components.<\/p>\n\n\n\n The issue was whether that consultant constituted a Dependent Agent Permanent Establishment (DAPE)<\/strong> of the US company under Article 5 of the India-USA DTAA.<\/p>\n\n\n\n The case emphasises that a DAPE inquiry normally requires examination of matters such as:<\/p>\n\n\n\n The ESM Group litigation also considered whether an Indian consortium partner could create an Indian PE for the foreign consortium member.<\/p>\n\n\n\n Under the India-USA DTAA, construction or installation projects are subject to a specified 120-day threshold<\/strong>.<\/p>\n\n\n\n The presence and activities of one consortium participant therefore cannot automatically be attributed to another without examining:<\/p>\n\n\n\n This is highly relevant for EPC contracts, infrastructure projects and international joint ventures.<\/p>\n\n\n\n Delhi High Court \u2013 [2025] 181 taxmann.com 254<\/strong><\/p>\n\n\n\n A Singapore enterprise provided legal advisory services to Indian clients.<\/p>\n\n\n\n Two employees remained in India for approximately 120 days<\/strong>, but only 44 days were stated to involve actual client-service activities<\/strong>. The remaining period involved vacation, business development and other activities.<\/p>\n\n\n\n Article 5(6) of the India-Singapore DTAA creates a Service PE where qualifying services continue beyond the treaty threshold.<\/p>\n\n\n\n The important issue was therefore not simply:<\/p>\n\n\n\n How many days were the employees physically present in India?<\/p>\n<\/blockquote>\n\n\n\n but:<\/p>\n\n\n\n How many days were relevant qualifying services actually furnished in India?<\/p>\n<\/blockquote>\n\n\n\n This distinction may materially affect the Service PE analysis.<\/p>\n\n\n\n Companies sending employees into India should therefore maintain detailed:<\/p>\n\n\n\n The presentation identifies this as an important 2026 Supreme Court decision concerning the India-Mauritius DTAA<\/strong>.<\/p>\n\n\n\n The structure involved:<\/p>\n\n\n\n The Supreme Court’s official judgment dated 15 January 2026<\/strong> confirms that the litigation concerned Mauritian investment entities holding investments ultimately connected with India.

Relevant factors included:<\/p>\n\n\n\n The core treaty issue was the tie-breaker rule under Article 4 of the India-Singapore DTAA<\/strong>.<\/p>\n\n\n\n Where a person is treated as resident in both countries, the treaty examines sequentially concepts such as:<\/p>\n\n\n\n The entire pattern of personal and economic relations has to be considered.<\/p>\n\n\n\n NRIs, founders and internationally mobile executives may therefore benefit from a structured NRI taxation and FEMA review<\/a>, particularly where residence can potentially arise in two countries.<\/p>\n\n\n\n Mumbai ITAT \u2013 [2025] 179 taxmann.com 264<\/strong><\/p>\n\n\n\n The official ITAT order confirms that the assessee was an Irish tax resident engaged in aircraft leasing and had leased aircraft to Indian airlines on a dry-lease basis<\/strong>. (Income Tax Appellate Tribunal<\/a>)<\/p>\n\n\n\n The aircraft remained owned by the foreign lessor and was to be returned following completion of the operating lease.<\/p>\n\n\n\n The significant question was:<\/p>\n\n\n\n The issue illustrates the fundamental \u201cdisposal test\u201d in PE jurisprudence.<\/p>\n\n\n\n For a fixed-place PE, the enquiry ordinarily extends beyond whether an asset happens to be situated in India. One must examine whether there is a place of business at the disposal of the foreign enterprise through which its business is carried on<\/strong>.<\/p>\n\n\n\n The same aircraft-leasing litigation considered penal interest arising because of delayed payment of lease rentals<\/strong>.<\/p>\n\n\n\n Article 11 of the India-Ireland DTAA specifically addresses the meaning of interest and also contains relevant wording concerning penalty charges for late payment.<\/p>\n\n\n\n This demonstrates why foreign-remittance certification cannot safely be based merely on the description appearing on an invoice.<\/p>\n\n\n\n A remittance described as:<\/p>\n\n\n\n must be analysed according to its legal substance and applicable treaty provision<\/strong>.<\/p>\n\n\n\n Delhi High Court \u2013 [2024] 162 taxmann.com 865<\/strong> The UK parent company gave a corporate guarantee to an overseas bank in connection with lending to its Indian subsidiary and received a guarantee commission from the Indian company.<\/p>\n\n\n\n Two important questions arose:<\/p>\n\n\n\n A corporate guarantee does not itself necessarily create a conventional debt claim between guarantor and Indian borrower.<\/p>\n\n\n\n The source and situs of the income must be separately examined under domestic law and treaty principles.<\/p>\n\n\n\n These issues are highly relevant to multinational groups and cross-border financing arrangements.<\/p>\n\n\n\n Delhi High Court \u2013 Full Bench<\/strong><\/p>\n\n\n\n The case concerns a UAE enterprise having a Fixed Place \/ Service PE in India while suffering losses at the global enterprise level.<\/p>\n\n\n\n The question was whether profit could nevertheless be attributed to its Indian PE under Article 7 of the India-UAE DTAA<\/strong>.<\/p>\n\n\n\n Article 7 applies the separate-enterprise principle: profits attributable to a PE are determined by considering the PE as if it were a distinct and separate enterprise dealing independently with its head office.<\/p>\n\n\n\n The Delhi High Court’s official records confirm Full\/Special Bench proceedings concerning Hyatt International Southwest Asia Ltd.

(CA Alok Kumar<\/a>)<\/p>\n\n\n\n Before deciding TDS or remitting a cross-border payment, businesses should ordinarily examine:<\/p>\n\n\n\n This is why a foreign-remittance certificate is ultimately an international-tax opinion supported by facts<\/strong>, not merely a portal-filing exercise.<\/p>\n\n\n\n A Permanent Establishment or PE generally represents a sufficient business presence of a foreign enterprise in another country to permit taxation of profits attributable to that presence.<\/p>\n\n\n\n The precise definition depends on the relevant DTAA.<\/p>\n\n\n\n No.<\/p>\n\n\n\n Common ownership alone does not automatically establish a PE. The functions, control, premises, agency relationship and applicable Article 5 provisions must be examined.<\/p>\n\n\n\n Some Indian tax treaties deem a foreign enterprise to have a PE where it furnishes services in India through employees or other personnel for more than a specified duration.<\/p>\n\n\n\n The threshold differs between treaties.<\/p>\n\n\n\n Certain treaties, including the India-USA DTAA, restrict taxation of technical or consultancy services unless technical knowledge, experience, skill, know-how or processes are made available<\/strong> to the recipient so that the recipient can apply them independently.<\/p>\n\n\n\n No.<\/p>\n\n\n\n The applicable Form 145 and Form 146 filing requirement<\/a> depends upon the taxability of the remittance, amount, applicable treaty and statutory route.<\/p>\n\n\n\n Treaty benefit is generally examined alongside the applicable domestic-law provisions and statutory treaty rules, subject to residence, documentation, beneficial ownership, anti-abuse provisions and other applicable conditions.<\/p>\n\n\n\n The International Tax Case Laws 2026<\/strong> demonstrate that cross-border taxation increasingly turns on detailed factual and treaty analysis.<\/p>\n\n\n\n A leased aircraft may not necessarily create a PE. An employee’s physical presence does not necessarily mean that every day counts towards a Service PE. An Indian affiliate or agent does not automatically constitute a PE. Online access to information does not automatically become royalty or technical-service income. Likewise, residence cannot be determined merely by citizenship, FEMA status or ownership of a house.<\/p>\n\n\n\n For businesses, NRIs, multinational groups, exporters, importers and professionals making overseas payments, the practical sequence should therefore be:<\/p>\n\n\n\n The same analysis now feeds directly into Form 145 and Form 146 certification under the Income-tax Act, 2025<\/strong>.<\/p>\n\n\n\n For practical assistance relating to DTAA analysis, NRI taxation, withholding on non-resident payments, foreign remittances and CA certification, see:<\/p>\n\n\n\n Form 145 & Form 146 \u2013 CA Certificate for Foreign Remittance<\/a><\/p>\n\n\n\n\n
