Three separate PE arguments, all rejected on these facts
The tax department tried three different routes to find a PE, and the tribunal rejected each. A fixed-place PE failed because the Indian subsidiary's own premises weren't "at the parent's disposal" for the parent's main business, the subsidiary was doing its own support work, not hosting the parent's revenue-earning activity. A service PE failed because the subsidiary's services went to the parent's foreign customers, not to anyone in India, and the parent's own staff visits to India were oversight, not service delivery. A dependent-agent PE failed because the relationship was principal-to-principal, an arm's length service arrangement, and the Indian subsidiary had no authority to sign contracts for the parent. Saving the parent money through the arrangement, on its own, doesn't create a fixed place of business either.
This is precedent to lean on, not a rule to assume
A tribunal ruling on one company's specific facts is real, useful, and currently favourable, but it isn't the same as a settled rule that applies automatically to every cost-plus subsidiary. PE determinations turn on your actual facts: what your Indian team really does day to day, whether your parent's own staff are the ones directing that work (versus your Indian team managing itself), whether anyone in India signs contracts or negotiates terms with your parent's customers, and whether the arrangement has genuinely been priced and documented as an independent service, the same discipline your Form 3CEB filing already requires. As of this page's last review, no High Court appeal of this ruling has surfaced, but tax department appeals can take time to become public, and this is exactly the kind of favourable-but-appealable position worth re-checking before leaning on it for a major decision.
What goes wrong without a CA
The common mistake isn't ignoring this question, it's never asking it at all. A subsidiary that has diligently filed Form 3CEB every year can still be structured in a way that drifts toward PE exposure over time: a parent's employee who starts spending real time in India directing the subsidiary's work, a subsidiary that starts fielding calls from the parent's own customers, or a parent representative who ends up signing something with an Indian counterparty. None of that shows up on a transfer-pricing filing. It shows up years later, in an assessment that reaches past the subsidiary's own cost-plus fee and asks for tax on the PARENT's profits attributable to India, a far larger number than anything the subsidiary itself ever declared.
