On 16 July 2026 India’s Ministry of Finance notified the protocol amending the DTAA with Sri Lanka. The protocol, effective in India for fiscal years beginning on or after 1 April 2027, inserts a Principal Purpose Test (PPT) and replaces the treaty preamble to curb treaty shopping.
What is the current change?
India and Sri Lanka amended their DTAA to add an explicit anti‑abuse rule — the Principal Purpose Test — and to revise the preamble to state that the treaty’s object is to eliminate double taxation without creating opportunities for tax evasion, avoidance or treaty shopping. The protocol entered into force after domestic completion and will apply in India from fiscal years starting 1 April 2027.
Why it matters for governance and the economy
- Domestic resource mobilisation: The PPT reduces profit shifting and withholding tax leakage, strengthening revenue collection for public services and fiscal targets.
- Rule‑based international cooperation: The change aligns bilateral practice with OECD/G20 BEPS Action 6 and India’s use of the MLI to modernise its treaty network.
- Investor certainty and compliance cost: While curbing abuse, PPT may increase compliance burden and dispute risk for bona fide cross‑border investors unless administration provides clarity.
- Regional relations: Technical tax rules shape bilateral investment flows and financial governance between neighbouring economies.
Key features of the amended DTAA
- PPT insertion: Treaty benefits may be denied where it is reasonable to conclude that securing those benefits was one of the principal purposes of an arrangement or transaction.
- Preamble revision: The new preamble explicitly rejects using the treaty to create opportunities for non‑taxation or reduced taxation through avoidance or treaty shopping.
- Temporal application: India applies amended provisions to income for fiscal years beginning on or after 1 April 2027.
- Implementation route: Amendment effected by protocol signed in 2024 and brought into force by completion of domestic procedures in both countries.
Legal mechanics of the Principal Purpose Test (PPT)
PPT is a facts‑and‑circumstances test. Authorities assess whether securing treaty benefits was one of the principal purposes. Relevant factors include the structure and substance of transactions, commercial rationale, contractual terms, and the presence of genuine business activities in the treaty state. PPT is intentionally flexible to catch novel avoidance schemes but that flexibility creates interpretative scope for tax administrations and taxpayers.
Alignment with global standards
- BEPS Action 6: PPT and preamble changes implement the BEPS minimum standard to prevent treaty abuse.
- Multilateral Instrument (MLI): India uses the MLI and bilateral protocols to update treaties rapidly and uniformly.
- Institutions involved: Ministry of Finance, Central Board of Direct Taxes (CBDT), OECD/G20 forums, and domestic adjudicatory bodies (AAR, tax tribunals, courts).
Economic consequences of treaty shopping and PPT’s corrective effect
- Revenue erosion: Treaty shopping diverts taxable income to low‑tax or no‑tax jurisdictions, reducing corporate and withholding tax receipts.
- Market distortion: Artificial routing favours entities that exploit treaty networks over genuine local competitors.
- PPT effect: By denying benefits where treaty access was a principal purpose, PPT restores tax outcomes closer to economic substance, protecting the tax base and competitive neutrality.
- Distributional impact: Protecting corporate tax revenue reduces pressure to raise regressive indirect taxes that disproportionately affect lower income groups.
Administrative and compliance challenges
| Challenge | Implication | Mitigation |
|---|---|---|
| Subjective assessment of purpose | Greater litigation, inconsistent rulings, investor uncertainty | CBDT guidance, illustrative examples, safe‑harbours |
| Proof of substance | Transaction documentation burden on taxpayers | Advance rulings and standardised substance criteria |
| International disagreement | Cross‑border disputes and double taxation risk | Stronger Mutual Agreement Procedure (MAP) capacity and arbitration |
| Administration capacity | Operational delays and inconsistent audits | Training, specialised anti‑abuse units, data analytics |
Ethical and policy dimensions
- Law versus spirit: Aggressive tax planning may comply with formal law but violate the treaty’s object; PPT treats such planning as inconsistent with treaty purpose.
- Distributive justice: Large‑scale avoidance shifts fiscal burden to ordinary taxpayers and reduces funds for public goods.
- Corporate responsibility: Firms operating across borders face ethical expectations to pay tax where value is created; treaty benefits should reflect genuine economic activity.
Operational measures and way forward
- CBDT guidance: Issue clear rules, fact‑sheets and examples on PPT application to reduce subjectivity.
- Advance rulings and MAP: Strengthen Authority for Advance Rulings and Mutual Agreement Procedure to resolve disputes and provide pre‑transaction clarity.
- Safe‑harbours and substance tests: Define objective thresholds for routine cross‑border activities to limit uncertainty for genuine investors.
- Capacity building: Train tax officers in commercial analysis, transfer pricing, and forensic accounting; use data analytics to detect treaty abuse patterns.
- International cooperation: Use BEPS monitoring forums and treaty partners’ exchanges of information to implement consistent anti‑abuse results.
Model Questions
1. Explain the economic consequences of treaty shopping on domestic resource mobilisation. How does the inclusion of the Principal Purpose Test (PPT) in tax treaties address these consequences? [GS-III: Economic Development]
PPT reduces revenue leakage by denying treaty benefits where obtaining them was a principal purpose, thereby limiting profit shifting and withholding tax avoidance. This protects corporate tax and withholding receipts, improves competitive neutrality between domestic and cross‑border firms, and lowers reliance on regressive indirect taxes. PPT aligns tax outcomes with economic substance and restores portions of the domestic tax base previously eroded by treaty shopping.
2. Analyse the role of international cooperation frameworks, specifically the OECD/G20 BEPS project, in reforming India’s bilateral tax diplomacy. [GS-II: International Relations]
BEPS Action 6 sets minimum standards to prevent treaty abuse; India adopts PPT and revised preambles to meet these standards. The Multilateral Instrument (MLI) and bilateral protocols enable rapid, consistent treaty updates. Participation in BEPS strengthens technical capacity, promotes information exchange, and reduces arbitrage across jurisdictions, embedding common rules in India’s treaty network and improving credibility in international tax diplomacy.
3. While anti‑abuse provisions secure revenues, they may increase tax uncertainty for investors. Discuss administrative challenges of implementing the PPT and suggest measures to balance revenue protection with investment certainty. [GS-III: Economic Development]
PPT’s subjectivity raises litigation risk, inconsistent rulings and compliance costs. Administrations may struggle to assess commercial purpose and substance. Remedies include CBDT guidance with illustrative tests, advance rulings, strengthened MAP and arbitration, objective safe‑harbours, and officer training. These measures reduce ambiguity, speed dispute resolution and protect bona fide investors while enabling enforcement against abusive arrangements.
4. Evaluate the ethical dimensions of aggressive tax planning and treaty shopping by multinationals in the context of distributive justice. [GS-IV: Ethics, Integrity and Aptitude]
Aggressive planning, though legally formatted, shifts tax burdens away from profitable corporations to households through lower public spending or higher indirect taxes. Ethically it undermines fairness and social contract obligations of firms benefiting from public goods. Anti‑abuse rules like PPT reintroduce moral accountability, ensuring multinational tax positions reflect economic substance and contribute equitably to societies where value is generated.
