Executive Overview: In international taxation, Double Taxation Avoidance Agreements (DTAAs) entered into by the Government of India under Section 90 of the Income-tax Act, 1961 (and Section 393/Section 90 of the 2025 Act) serve as the primary legal shield against double economic taxation. Under Section 90(2), non-resident taxpayers are entitled to apply treaty provisions to the extent they are more beneficial than the domestic Income-tax Act. However, cross-border treaty practice has experienced profound structural disruption following three seismic developments: (1) the landmark Supreme Court ruling in AO (International Taxation) v. Nestle SA (2023), which upended decades of industry reliance on the Most Favoured Nation (MFN) clause for lower dividend, royalty, and FTS withholding tax rates; (2) the global implementation of the Multilateral Instrument (MLI) and the mandatory Principal Purpose Test (PPT) to combat treaty abuse and conduit routing; and (3) stringent procedural prerequisites under Section 90(4) and 90(5), requiring electronic filing of Form 10F on the income tax portal even for foreign companies lacking an Indian PAN. This masterclass provides an exhaustive legal and operational roadmap for cross-border tax advisors, international CFOs, and certifying Chartered Accountants managing treaty files in assureOffice.
- The Supreme Court Nestle MFN Ruling: Why automatic invocation of MFN clauses (5% vs 10% withholding) is dead, the dual-condition test for third-party OECD membership, and mandatory Section 90(1) notification requirements.
- The Principal Purpose Test (PPT) & Beneficial Ownership: Moving beyond mailbox paper entities; substance requirements (local employees, physical office, independent directors, commercial risk).
- Procedural Gateway under Section 90(4)/(5): Valid Tax Residency Certificate (TRC) standards and electronic Form 10F compliance for non-residents without PAN.
- Withholding Certification & Downstream Reconciliation: Linking treaty positions with Form 146 certifications and Tax Audit Clause 34 reviews in assureTax.
1. The Supreme Court Nestle Ruling: Demystifying the Most Favoured Nation (MFN) Clause
Many of India's bilateral tax treaties with developed nations—including the Netherlands, France, Switzerland, Sweden, Spain, Hungary, and Belgium—contain an MFN clause in their protocols. Under an MFN clause, if India subsequently signs a tax treaty with another OECD member country providing a lower rate of withholding tax (e.g., 5% instead of 10%) or a more restricted scope on dividends, interest, royalties, or fees for technical services (FTS), that lower rate or narrower scope shall automatically apply to the earlier treaty partner.
For over two decades, taxpayers and multinational corporate groups claimed the 5% concessional withholding rate on dividends under the India–Netherlands, India–France, and India–Switzerland treaties by pointing to subsequent treaties signed by India with countries like Slovenia, Colombia, and Lithuania (which provided 5% dividend tax rates). Taxpayers argued that the MFN benefit took effect automatically without requiring any bilateral notification.
On October 19, 2023, the Supreme Court of India delivered its historic judgment in Assessing Officer (International Taxation) v. Nestle SA (Civil Appeal No. 1420 of 2023), definitively overruling the Delhi High Court and establishing two non-negotiable statutory principles:
| Legal Question | Taxpayer's Contention (Pre-2023 Practice) | Supreme Court's Final Binding Ruling (Nestle SA) |
|---|---|---|
| Requirement of Notification u/s 90 | The Protocol is an integral part of the treaty; once signed, MFN benefits operate automatically without needing domestic notification. | Mandatory Notification: Under Section 90(1) of the Income-tax Act and Article 253 of the Constitution of India, a treaty or protocol amendment cannot be enforced in Indian municipal law unless a separate, formal notification is published in the Official Gazette of India bringing the amended terms into effect. |
| Timing of OECD Membership | The third-party country (e.g., Slovenia, Colombia, Lithuania) only needs to be an OECD member at the time the taxpayer claims the MFN benefit. | Membership at Treaty Execution Date: The third state must have been a member of the OECD on the exact date when India signed the bilateral treaty with that third state, not on a later date. Since Slovenia and Lithuania joined the OECD years after their treaties with India were executed, they did not qualify as "OECD member countries" under the protocol! |
Practical Fallout of the Nestle Judgment
The practical consequence for international corporate finance is massive: foreign companies that claimed a 5% dividend or FTS withholding rate under the India–Netherlands, France, or Swiss treaties without a formal notification are now facing reassessment notices from the International Taxation Ward demanding the differential 5% tax (the difference between 10% and 5%) plus 1% to 1.5% monthly interest under Section 201(1A)! Indian payers who withheld only 5% face being treated as assessees-in-default. International tax advisors must review past foreign remittances and manage dispute files using assureNotice.
2. Anti-Treaty Abuse: The Multilateral Instrument (MLI) and Principal Purpose Test (PPT)
Even where a bilateral treaty provides a clear tax exemption or lower rate, the international tax landscape has fundamentally shifted with the implementation of the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI), which entered into force for India on April 1, 2020.
The Principal Purpose Test (PPT) under Article 7 of the MLI
The PPT operates as a blanket general anti-avoidance rule embedded into bilateral treaties. Under Article 7(1) of the MLI:
"A benefit under the Covered Tax Agreement shall not be granted in respect of an item of income if it is reasonable to conclude, having regard to all relevant facts and circumstances, that obtaining that benefit was one of the principal purposes of any arrangement or transaction that resulted directly or indirectly in that benefit, unless it is established that granting that benefit in these circumstances would be in accordance with the object and purpose of the relevant provisions."
Notice the critical words: "one of the principal purposes". The tax authority is not required to prove that tax avoidance was the sole or dominant purpose; it is sufficient that tax benefit was one of the key motivating factors!
Beneficial Ownership: Beyond Shell Companies
In cross-border royalty, interest, and dividend payments, DTAA Articles 10, 11, and 12 restrict lower tax rates to the "Beneficial Owner" of the income. Indian tax authorities, backed by judicial precedents (such as the Authority for Advance Rulings in Tiger Global and Delhi ITAT in Blackstone), routinely pierce the corporate veil of foreign holding entities in jurisdictions like Mauritius, Singapore, Cyprus, or the Netherlands:
- Conduit Entities (No Substance): If a Singapore or Dutch intermediate holding company has zero independent employees, no dedicated physical office, director meetings conducted by local nominee corporate secretaries, and contractual obligations to immediately pass on 90%+ of dividends or royalties to an ultimate US or Cayman parent within 48 hours, the entity is a pure conduit. Beneficial ownership is denied, the DTAA rate is revoked, and full domestic tax (plus penalties) is levied.
- Substantive Commercial Presence: To withstand PPT scrutiny and substantiate beneficial ownership, the non-resident entity must demonstrate: (a) genuine commercial rationale for incorporation, (b) local senior management with technical decision-making authority, (c) adequate operating expenditure incurred locally, and (d) independent bank account operation with discretionary capital deployment. Tax teams can document and preserve these substance files within client workspaces in assureOffice.
3. Practical Challenges, Case Studies & Worked Numerical Illustrations
Challenge 1: Dividend Remittance to Dutch Holding Company Post-Nestle
The Practical Situation: Indigo Tech India Pvt. Ltd. declares a dividend of ₹50 crore on October 15, 2026. Its 99.9% parent company is Indigo BV, incorporated in the Netherlands. Indigo BV claims that under the MFN clause of the India–Netherlands DTAA read with the India–Slovenia treaty, the applicable dividend withholding tax rate is 5%. What rate must Indigo India deduct?
The Technical Resolution & Financial Computation:
- Post-Nestle Position: The Supreme Court has held that the MFN benefit cannot be applied without a specific notification under Section 90(1). The Government of India has not issued any notification extending a 5% rate to the India–Netherlands treaty. Furthermore, Slovenia was not an OECD member when its treaty with India was signed.
- Statutory Application: Indigo India must reject the 5% MFN claim. Under Article 10(2) of the India–Netherlands DTAA, the notified treaty rate for dividends is 10%. (Domestic Act rate under Section 115A is 20% + surcharge + cess; because 10% DTAA is more beneficial under Section 90(2), 10% applies).
- Tax Calculation: On ₹50 crore dividend, TDS at 10% = ₹5,00,000,000. (If Indigo India had incorrectly withheld 5% [₹2.50 crore], it would face an immediate recovery demand for ₹2.50 crore plus 18% annual interest under Section 201(1A)!). Certifying CAs issuing Form 146 must verify the 10% rate and record the exact challan details in assureTax.
Challenge 2: Electronic Form 10F Filing for Non-Residents Without an Indian PAN
The Practical Situation: A Japanese engineering firm, Tokyo Heavy Industries Ltd., provides technical inspection services to an Indian steel mill for USD 100,000 (~₹84,00,000). Tokyo Heavy has a valid Tax Residency Certificate (TRC) issued by the National Tax Agency of Japan. However, the Japanese TRC contains only the company's registered name and address; it omits the tax identification number, legal status, and applicable treaty article. Tokyo Heavy does not hold an Indian PAN. Can it claim the 10% DTAA rate?
Step-by-Step Resolution:
- Under Section 90(4) and 90(5), where the TRC does not contain all prescribed particulars specified in Rule 21AB, furnishing Form 10F is mandatory.
- Under CBDT notifications, manual physical Form 10F is completely discontinued. Electronic filing on the e-Filing portal is mandatory.
- The Portal Registration Workflow: Tokyo Heavy registers on the Indian Income Tax e-Filing portal under the category: "Non-Residents not holding and not required to have a PAN". It provides its Japanese Corporate Number (TIN), email address, and phone number, attaches its Japanese TRC PDF, and generates an electronic Form 10F.
- The Indian steel mill's certifying Chartered Accountant verifies the e-Form 10F acknowledgement number and signs Form 146, allowing 10% withholding under Article 12 of the India–Japan DTAA. Corporate accounts teams can track foreign vendor registration workflows inside assurePractice.
Challenge 3: The "Make Available" Clause Defense in Indian IT Contracting
The Practical Situation: An Indian financial services company, Bharat Capital Ltd., pays USD 150,000 (~₹1.26 crore) to a UK cybersecurity consulting firm for a comprehensive vulnerability assessment and penetration test of its core banking application. The UK firm remotely tests the servers, generates an audit vulnerability report, and recommends remediation patches. The Assessing Officer claims the service constitutes Fees for Technical Services (FTS) taxable at 20% under Section 9(1)(vii). The taxpayer invokes Article 13 of the India–UK DTAA.
The Technical Resolution & Precedent Analysis:
- Domestic Law: Under Section 9(1)(vii), technical, managerial, or consultancy services are deemed to accrue in India. Testing services fall squarely under the domestic FTS net.
- Treaty Protection (Article 13(4)(c) India–UK DTAA): The India–UK treaty contains a restrictive "Make Available" clause. Technical services are taxable only if the service "makes available technical knowledge, experience, skill, know-how, or processes, or consists of the development and transfer of a technical plan or technical design".
- Judicial Principles: The Karnataka High Court in De Beers and Delhi High Court in Guy Carpenter established that "make available" requires that the recipient is enabled to perform the technical function themselves in the future without technical reliance on the service provider.
- Conclusion: Because Bharat Capital merely received an end-product assessment report and was not trained or transferred the underlying penetration testing methodologies, technical knowledge was NOT made available. The payment constitutes business profits under Article 7 and is NOT taxable in India in the absence of a PE. Bharat Capital remits funds without TDS, certifying the position via Form 146 and filing Part C of Form 145 on the portal.
4. Step-by-Step DTAA Eligibility and Withholding Audit Checklist
To establish a bulletproof cross-border treaty defense before certifying foreign payments, international tax teams should follow this structured ten-step verification protocol:
| Step | Audit Checkpoint | Mandatory Source Documentation | Key Risk Avoided |
|---|---|---|---|
| 01 | Examine Covered Tax Agreement Status | Bilateral DTAA and MLI Synthesized Text | Applying un-notified treaties or missing MLI modifications. |
| 02 | Verify Current-Year Tax Residency Certificate | Original TRC issued by foreign tax authority | Expired or previous-year TRCs lead to immediate treaty disqualification. |
| 03 | Audit Form 10F Compliance | Portal-generated e-Form 10F acknowledgement PDF | Relying on manual paper Form 10F violates Rule 21AB. |
| 04 | Obtain Robust No-PE Declaration | Annual signed declaration on foreign vendor letterhead | Absence of PE certificate exposes payer to Section 201 liability. |
| 05 | Apply Principal Purpose Test (MLI Art 7) | Commercial justification memo, local employee/substance proof | Denial of treaty relief for conduit holding structures under PPT. |
| 06 | Verify Beneficial Ownership of Payee | Audited financial statements of foreign entity, board minutes | Flow-through entities passing money to non-treaty third parties fail beneficial ownership. |
| 07 | Examine MFN Notification Status Post-Nestle | CBDT Section 90(1) official gazette notification registry | Un-notified 5% MFN claims result in automatic 5% tax recovery plus interest. |
| 08 | Check "Make Available" Clause Applicability | Master Service Agreement and technical scope of deliverables | Ensure routine consultancy meets the technology transfer test before claiming 0% tax. |
| 09 | Calculate Flat Treaty Rate (No Surcharge/Cess) | Withholding calculation schedule in assureTax | Erroneously adding 4% Health & Education Cess on top of flat DTAA rates. |
| 10 | Digitally Sign Form 146 & File Part C Form 145 | Form 146 with ICAI UDIN and e-Filing Form 145 receipt | Ensures full AD bank wire clearance and synchronized Tax Audit Clause 34 files. |
5. Frequently Asked Questions (Practitioner FAQ Bank)
- What is the legal effect of Section 90(2) of the Income-tax Act?
Section 90(2) establishes that where India has entered into a DTAA, the provisions of the domestic Income-tax Act apply to the non-resident assessee only to the extent they are more beneficial than the treaty. If the treaty exempts income or provides a lower tax rate, the treaty prevails over domestic law. - What did the Supreme Court decide in the Nestle MFN case?
The Supreme Court held that: (a) An MFN clause in a protocol cannot be applied by taxpayers unless the Government of India issues a separate, formal notification under Section 90(1) in the Official Gazette; and (b) The third-party country must have been an OECD member on the date when the treaty with India was signed. - Can a taxpayer claim a 5% dividend tax rate under the India–Netherlands DTAA today?
No. Because the Government has not issued an official notification extending the 5% rate to the India–Netherlands treaty and the third-party reference countries were not OECD members on treaty signing dates, dividends are subject to the notified 10% DTAA withholding rate. - What is the Principal Purpose Test (PPT) under the MLI?
The PPT is an anti-treaty abuse rule under Article 7 of the Multilateral Instrument. It denies treaty benefits if it is reasonable to conclude that obtaining the tax benefit was one of the principal purposes of the transaction or arrangement, unless granting the benefit aligns with the treaty's object and purpose. - What are the requirements for a valid Tax Residency Certificate (TRC)?
Under Section 90(4), the TRC must be issued by the revenue authority of the foreign country, confirming that the entity is a resident of that country for tax purposes during the relevant financial year. - When is Form 10F required in addition to a TRC?
Under Rule 21AB, if the TRC does not contain all prescribed details (status, nationality, tax identification number, period of residence, and address), the non-resident must electronically furnish Form 10F on the Indian e-Filing portal. - Can a foreign company file electronic Form 10F if it does not have an Indian PAN?
Yes. The Income Tax portal allows non-residents not holding a PAN to register using their foreign Tax Identification Number (TIN), email, and phone OTP to file and e-verify Form 10F. - Is Health & Education Cess (4%) added to DTAA withholding rates?
No. Courts and Tribunals have consistently held that the withholding tax rates specified in DTAAs (e.g., 10% on royalties or 15% on dividends) are all-inclusive statutory caps. Surcharge and 4% cess cannot be added on top of a treaty rate. - What is the "Make Available" clause in Fees for Technical Services (FTS)?
Under DTAAs with countries like the US, UK, Singapore, and Canada, technical services are taxable as FTS only if the service "makes available" technical knowledge, experience, skill, or processes, enabling the recipient to apply the technology independently in the future. - How does a "Permanent Establishment" (PE) affect DTAA taxation?
Under Article 7 of standard DTAAs, business profits of a foreign enterprise are taxable in India only if the enterprise carries on business through a Permanent Establishment (Fixed Place, Service, or Agency PE) situated in India, and only to the extent profits are attributable to that PE. - What is a "Conduit Company," and why does it fail beneficial ownership?
A conduit company is an intermediate entity established in a low-tax jurisdiction with minimal substance, whose primary function is to channel income (dividends, interest, or royalties) to an ultimate parent in another country. It is denied treaty benefits under beneficial ownership and PPT rules. - What is the difference between an Indian Tax Residency Certificate and an apostilled Certificate of Incorporation?
A Certificate of Incorporation proves legal existence under foreign corporate law, but does NOT prove tax residency. A TRC must be issued specifically by the foreign government's direct tax authority (such as US IRS Form 6166 or UK HMRC TRC). - What happens if an Indian payer deducts tax at 10% under DTAA but the vendor's TRC is found to be invalid?
The Indian payer is treated as an assessee-in-default under Section 201 for short-deduction of tax (recomputed at the domestic 20% plus surcharge and cess rate), liable for 1% monthly interest under Section 201(1A) and potential 100% expense disallowance under Section 40(a)(i). - How does Form 146 interact with DTAA compliance?
Form 146 is the statutory certificate issued by a Chartered Accountant certifying the accuracy of the DTAA rate, TRC, Form 10F, and No-PE documentation before an outward foreign remittance is processed by the bank. - How does assureOffice help practitioners manage DTAA and cross-border tax files?
The assureOffice Practice Suite streamlines cross-border compliance by archiving foreign vendor TRCs and Form 10F certificates in client workspaces, validating Form 146 certifications in assureTax, auditing Clause 34 disclosures, and monitoring international tax notices in assureNotice.
