Permanent establishment determination requires treaty-specific functional analysis, barring inapplicable MLI reliance and ad hoc profit attribution.
The final assessment order following DRP directions was governed by the procedure under section 144C rather than the limitation applicable to the draft assessment order, and was therefore not time-barred. For the relevant assessment year, permanent establishment had to be determined under Article 5 of the applicable India-UK tax treaty; inapplicable MLI provisions or their underlying spirit could not be invoked. Dependent-agent, fixed-place and service PE required separate treaty-specific examination of contractual arrangements, conduct, and functions, assets and risks, with the Revenue bearing the burden of proof. Profit attribution required FAR analysis and could not rest on an ad hoc percentage; arm's-length remuneration could eliminate further attribution if fully compensatory.
Issues: (i) Whether the final assessment order passed after DRP directions was barred by limitation; (ii) Whether the MLI or its underlying spirit could be invoked to determine PE for assessment year 2020-21; and (iii) Whether the alleged PE and the 30% profit attribution could be sustained on the existing record.
Issue (i): Whether the final assessment order passed after DRP directions was barred by limitation.
Analysis: The retrospective amendment clarified that the limitation under Section 153 governs the passing of the draft assessment order, whereas the final assessment order following DRP directions is governed by Section 144C.
Conclusion: The final assessment order was not time-barred. Against the assessee.
Issue (ii): Whether the MLI or its underlying spirit could be invoked to determine PE for assessment year 2020-21.
Analysis: The relevant MLI provisions were admittedly inapplicable to the assessment year. The existence of a PE must therefore be determined strictly under Article 5 of the India-United Kingdom Double Taxation Avoidance Agreement applicable for that year.
Conclusion: Neither the MLI nor its underlying spirit can be invoked to determine PE for the relevant year. In favour of the assessee.
Issue (iii): Whether the alleged PE and the 30% profit attribution could be sustained on the existing record.
Analysis: Determination of a dependent-agent PE requires examination of the actual contractual arrangements and conduct, including control over pricing, credit risk, contractual obligations, performance responsibility, and the Indian entity's role in soliciting, negotiating, securing and processing orders. Fixed-place and service PE require separate satisfaction of their respective treaty conditions; the Revenue bears the burden of establishing a PE. Acceptance of an earlier assessment concerning another group entity does not create an estoppel for the relevant year. If a PE is found, profit attribution must follow a functions, assets and risks analysis. Arm's-length remuneration does not determine PE existence, but may eliminate further attribution where it fully captures the relevant functions and risks; ad hoc attribution is impermissible.
Conclusion: The PE issue and related profit attribution were remitted for fresh treaty-compliant determination; no final finding on PE or attributable profits was made. In favour of the assessee to the extent of remand.
Final Conclusion: The limitation challenge fails, while the PE inquiry and any profit attribution must be redetermined independently under the applicable treaty, without reliance on the MLI or an ad hoc percentage of receipts.
Ratio Decidendi: PE existence and resultant profit attribution must be determined independently for each year under the applicable treaty on the actual functions, assets, risks and conduct of the parties, and cannot rest on inapplicable MLI principles, prior group assessments or ad hoc attribution.
