Permanent establishment and arm's length attribution: deputed employees created a service PE, while preparatory back office functions did not.

Back office operations and stewardship activities did not create a permanent establishment because they were preparatory, auxiliary, or supervisory in character, and no agency permanent establishment arose where contracts were not concluded in India. However, deputed employees who retained lien with the foreign enterprise and rendered services in India did give rise to a service permanent establishment. For attribution, transactional net margin method was accepted as the appropriate transfer pricing method for the service permanent establishment, and arm's length remuneration could substantially exhaust further profit attribution only if it fully reflected the functions performed and risks assumed. Further attribution was therefore not barred in principle, but depended on the completeness of the arm's length analysis.

Issues: (i) Whether the Indian support entity constituted a permanent establishment under the treaty for back office operations, agency functions, stewardship activities, and deputation of employees; (ii) whether transactional net margin method was the appropriate method for determining arm's length price and whether remuneration at arm's length exhausted the profit attribution exercise; (iii) whether further profits could still be attributed to the permanent establishment despite arm's length remuneration.

Issue (i): Whether the Indian support entity constituted a permanent establishment under the treaty for back office operations, agency functions, stewardship activities, and deputation of employees.

Analysis: A permanent establishment under the treaty requires a fixed place through which business is carried on, and the analysis must be functional and factual. The back office activities were preparatory or auxiliary in character and fell within the exclusion for such activities. There was no agency permanent establishment because the Indian entity had no authority to conclude contracts and contracts were concluded outside India. Stewardship activities were only for quality control and confidentiality and did not amount to services rendered by the foreign enterprise to the Indian entity. By contrast, when employees of the foreign enterprise were deputed to India, retained their lien with the parent, and rendered services in India through the Indian entity, the treaty's service permanent establishment conditions were satisfied.

Conclusion: The foreign enterprise had no permanent establishment on account of back office operations or stewardship activities, but it did have a service permanent establishment in India on account of deputed employees.

Issue (ii): Whether transactional net margin method was the appropriate method for determining arm's length price and whether remuneration at arm's length exhausted the profit attribution exercise.

Analysis: The transfer pricing provisions require arm's length price to be determined by the most appropriate method having regard to the nature of the international transaction and the functions performed. For a service permanent establishment, transactional net margin method was appropriate because it measured net profit margin on a reliable operating base. Once the associated enterprise is remunerated at arm's length on a proper functional and factual basis, the remuneration can substantially capture the profit attributable to the services rendered.

Conclusion: Transactional net margin method was the appropriate method, and the 29 per cent cost-plus mark-up was accepted as correct.

Issue (iii): Whether further profits could still be attributed to the permanent establishment despite arm's length remuneration.

Analysis: Attribution under the treaty concerns profits economically connected with the permanent establishment. Arm's length remuneration may leave nothing further to attribute if it fully reflects the functions performed and risks assumed. However, if the transfer pricing analysis does not capture all functions or risks, additional attribution remains possible to that extent. The decisive test is whether the arm's length pricing exercise is exhaustive of the profit attributable to the permanent establishment.

Conclusion: Further attribution is not barred as a matter of principle, but it is unnecessary where arm's length remuneration fully reflects the relevant functions and risks; the ruling was upheld subject to that qualification.

Final Conclusion: The judgment modified the advance ruling only to the extent that stewardship activities were excluded from constituting a service permanent establishment, while deputation-based services remained within the treaty concept. The arm's length pricing method and the accepted mark-up were sustained, and further profit attribution was held to depend on whether the transfer pricing analysis fully captured the functions and risks of the permanent establishment.

Ratio Decidendi: Under the treaty, back office and stewardship functions that are preparatory, auxiliary, or merely supervisory do not create a permanent establishment, but deputed employees who retain their lien and render services in India can create a service permanent establishment; for attribution, arm's length remuneration may exhaust taxable profit only if it fully reflects all functions and risks.
