The single most consequential tax question for a foreign company operating in or with India is whether it has crossed the threshold that turns activity in India into profit taxable in India. That threshold has two doors, and a company can be pulled through either. The first is domestic law: the Income-tax Act, 1961 taxes a non-resident on income arising through a business connection in India. The second is the applicable tax treaty, which taxes the business profits of a foreign enterprise in India only to the extent they are attributable to a permanent establishment here. For a company resident in a country with which India has a treaty, the treaty concept of permanent establishment is usually the operative test, and understanding its contours is the difference between a predictable tax position and a disputed one.
A permanent establishment is not a single thing; it is a family of triggers. A fixed place of business, an office, a branch, a workshop or even space at a customer site that is at the enterprise's disposal, can constitute a fixed-place PE. A dependent agent who habitually concludes contracts in India in the enterprise's name, or plays the principal role leading to their conclusion, can constitute an agency PE even where the enterprise itself has no premises. A building site or installation project that lasts beyond the treaty threshold becomes a construction PE. And the furnishing of services in India, through employees or other personnel present beyond the days specified in the treaty, can create a service PE. Each is fact-specific, and the revenue examines substance, not the label the parties have put on the arrangement.
The arrangement that has generated the most litigation, and the most avoidable surprise, is the secondment of employees from a foreign group to an Indian entity. Companies frequently assume that placing their people inside an Indian subsidiary is internal and tax-neutral. The revenue does not see it that way, and the Supreme Court's reasoning in the Northern Operating Systems matter has sharpened the scrutiny of who the real employer is, who bears the risk and reward of the personnel, and whether the foreign entity is in substance supplying manpower. Where the answer points back to the foreign company, the seconded team can be treated as evidence of a taxable presence, with consequences that reach both the foreign entity's profits and the withholding obligations on the payments that funded the secondment.
Establishing that a permanent establishment exists is only the first half of the analysis; the harder, and more negotiable, half is attribution. India taxes the profits attributable to the PE, which requires a functional analysis of what the Indian presence actually does, the assets it uses and the risks it assumes, followed by a reasoned allocation of profit to those functions. This is where disputes are won and lost, because the revenue's attribution and the taxpayer's can differ by an order of magnitude. A foreign company that has documented its functions, priced its intra-group dealings at arm's length and prepared a defensible attribution position is in a fundamentally stronger place than one that concedes the PE and then argues attribution from a standing start.
Permanent establishment is also not the only way India taxes a foreign employer's footprint. Independently of any PE, the salary of an employee for work performed in India is generally taxable in India, which brings withholding obligations on employment income, and, depending on the employee's status and duration, potential exposure under the social security regime that governs international workers. A foreign company that sends staff to India for extended assignments can therefore face Indian payroll and withholding responsibilities even where it has taken care to avoid a corporate taxable presence, and overlooking that individual-level exposure is a common and costly blind spot.
The strategic posture we counsel is to treat permanent establishment as something to be managed by design rather than discovered by audit. That means mapping how people, agents, project sites and seconded staff actually operate in India against each PE trigger, structuring authority and contracting so that the intended tax position matches the commercial reality, documenting functions and inter-company terms contemporaneously, and, where a PE is genuinely unavoidable, preparing the attribution analysis before the revenue prepares its own. For a foreign company, this is not about avoiding Indian tax; it is about knowing precisely where the line sits and standing confidently on the side of it that the company has chosen. That clarity is what AMLEGALS builds for overseas clients before the question is ever asked by a tax officer.
