What Is a Service Permanent Establishment?
A Service Permanent Establishment (Service PE) is a category of Permanent Establishment created not by a fixed office or factory, but by the mere presence of a foreign enterprise's employees or other personnel in India furnishing services on its behalf. Where a Double Taxation Avoidance Agreement between India and the enterprise's home country contains a service PE clause, sending staff to work at an Indian client's premises, on a project site, or inside a group company for long enough turns that activity into a taxable establishment, even though the foreign enterprise owns no office, warehouse, or branch in India.
Service PE is the clause that most often catches consulting firms, IT services companies, engineering and EPC contractors, and multinational groups that second staff to an Indian affiliate. It does not appear in every Indian tax treaty, and where it does, the day-count threshold is set independently by each treaty. There is no single "90-day rule" that applies across the board — the number, and even whether a service PE clause exists at all, has to be read out of the specific treaty text.
Legal Basis
Domestic Law — Income-tax Act, 2025
Indian domestic law does not use the term "service PE." Under section 9(2)(c) of the Income-tax Act, 2025 (section 9(1)(i) of the Income-tax Act, 1961), income accruing through a "business connection" in India is deemed to accrue in India, and section 9(9) defines business connection broadly enough to capture sustained service activity carried on in India on behalf of a non-resident. "Permanent establishment" itself is defined only in outline at section 173(c) of the Income-tax Act, 2025 (section 92F(iiia) of the Income-tax Act, 1961), as including "a fixed place of business through which the business of the enterprise is wholly or partly carried on" — it does not set out a separate, more detailed service-PE test of its own.
Where a DTAA is in force, section 159(4) of the Income-tax Act, 2025 (section 90(2) of the Income-tax Act, 1961) lets the non-resident apply whichever of the treaty or the domestic law is more beneficial. In practice this means the treaty's Article 5 — not the general business-connection language — supplies the operative service PE test for any country whose treaty contains one.
DTAAs — Article 5 Service PE Clauses
Service PE clauses follow the UN Model Tax Convention rather than the OECD Model. Because India negotiated its treaty network over several decades with different partners, the presence and wording of a service PE clause differs treaty by treaty. Four points below are taken directly from the treaty texts:
- India-USA DTAA, Article 5(2)(l): a PE is created where an enterprise furnishes services (other than services taxable as included services under Article 12) through employees or other personnel, and either (i) the activity continues for more than 90 days in any twelve-month period, or (ii) the services are performed for a related enterprise (within the meaning of Article 9, Associated Enterprises) — clause (ii) carries no separate minimum-duration test of its own.
- India-UK DTAA, Article 5(2)(k): the furnishing of services, including managerial services (other than services taxable under Article 13), through employees or other personnel is a PE if the activity continues for more than 90 days in any twelve-month period, or if the services are performed for an associated enterprise (within the meaning of Article 10, Associated Enterprises) and continue for more than 30 days in any twelve-month period.
- India-Singapore DTAA, Article 5(6): the same two-tier structure — more than 90 days in any fiscal year for services generally, or more than 30 days in any fiscal year where the services are performed for a related enterprise. Services that are technical services as defined in Article 12 of that treaty are carved out of the clause.
- India-Thailand DTAA, Article 5(3)(b): a single threshold — the furnishing of services, including consultancy services, through employees or other personnel is a PE only where the activity continues, for the same or a connected project, for more than 183 days in any twelve-month period.
Not every DTAA has a service PE clause at all. Article 5 of the India-Germany DTAA and of the India-Japan DTAA contains no general furnishing-of-services clause at all. Both do carry a building-site, construction or supervisory PE that runs on a threshold of more than six months, and both carry one narrow deemed PE for services or facilities supplied in connection with the prospecting for, extraction or exploitation of mineral oils — Article 5(3) in the Germany treaty and Article 5(5) in the Japan treaty. Outside that oil-and-gas carve-in, a German or Japanese company sending staff to India for a service engagement can only be caught, if at all, under the fixed-place-PE or dependent-agent provisions of that treaty, because there is no general service PE clause to apply.
The lesson is structural, not a shortcut: never assume a day-count threshold from one treaty applies to another, and never assume a service PE clause exists at all until the specific DTAA in force between India and the enterprise's country of residence has been checked.
Service PE Thresholds — What the Treaty Text Actually Says
| DTAA | Article | General threshold | Related/associated-enterprise threshold |
|---|---|---|---|
| India-USA | 5(2)(l) | More than 90 days in any 12-month period | No separate day-count — any duration for a related enterprise (Article 9) qualifies |
| India-UK | 5(2)(k) | More than 90 days in any 12-month period | More than 30 days in any 12-month period, for an associated enterprise (Article 10) |
| India-Singapore | 5(6) | More than 90 days in any fiscal year | More than 30 days in any fiscal year, for a related enterprise |
| India-Thailand | 5(3)(b) | More than 183 days in any 12-month period (same or connected project) | Not separately provided |
| India-Germany | 5 | No general service PE clause; narrow deemed PE for mineral-oil services under Article 5(3) | Not applicable |
| India-Japan | 5 | No general service PE clause; narrow deemed PE for mineral-oil services under Article 5(5) | Not applicable |
Why Service PE Matters for Foreign Companies
Service PE is the provision most likely to surprise a foreign company that has deliberately avoided opening an office in India. Typical exposures include:
- A US or UK consulting or audit firm posting a team to an Indian client's premises for a multi-month engagement.
- An IT services company sending developers to work at a client's or group company's India office on an implementation or support project.
- An engineering or EPC contractor deploying supervisory or advisory personnel to an Indian project site, alongside or instead of a construction PE.
- A multinational group seconding staff into its own Indian subsidiary or joint venture to provide managerial or technical services — see global mobility secondments.
Once a service PE is triggered, India can tax the business profits attributable to that PE, computed on an arm's-length basis — the same attribution principle used in transfer pricing — as though the PE were an independent enterprise dealing with the rest of the foreign company at arm's length. The foreign company also picks up Indian tax filing and withholding obligations it would not have had if the engagement had stayed under the treaty threshold, or had been routed through a properly incorporated Indian subsidiary or branch office instead.
A Worked Example
An Indian subsidiary engages its US parent's engineering team to advise on a plant commissioning. Four engineers travel to India and work at the subsidiary's site for 140 days across a 12-month window. Because the US parent and the Indian subsidiary are related enterprises within the meaning of Article 9 of the India-USA DTAA, clause 5(2)(l)(ii) is the one that applies: it has no minimum-duration test of its own, so the engagement does not need to reach the 90-day general threshold in clause (i) for a service PE to arise. Had the same engineers instead been engaged by an unrelated Indian client for exactly the same 140 days, clause (i)'s 90-day threshold would apply and would already have been crossed.
Contrast this with the same fact pattern under the India-Germany DTAA. Because Article 5 of that treaty has no general furnishing-of-services clause, and plant commissioning is not the mineral-oil work caught by its Article 5(3), a German parent sending the same four engineers for the same 140 days creates no service PE. Its exposure, if any, would have to come from a fixed place of business or a dependent agent, neither of which a site visit of this kind ordinarily creates.
Managing Service PE Risk
- Identify the specific DTAA governing the engagement before assuming any day-count applies — some treaties have none.
- Track days of presence per engagement, against the exact treaty wording and the correct measurement period (a rolling 12-month period in some treaties, a fiscal year in others), not a generic "90-day" rule of thumb.
- Flag any service performed for a related or associated group entity separately — the day threshold for related-party services is often shorter, or absent altogether, compared with third-party engagements.
- Where an engagement is expected to run long or to recur, consider routing it through a properly incorporated Indian subsidiary rather than direct secondment, so the activity is taxed as ordinary business income of an Indian company rather than as PE profits of the foreign enterprise.
Frequently Asked Questions
Does every Indian tax treaty have a service PE clause?
No. Service PE clauses come from the UN Model Tax Convention, and some of India's treaties do not include one. The India-Germany and India-Japan DTAAs, for example, have no general furnishing-of-services clause in Article 5 — only a construction or supervisory PE of more than six months and a narrow deemed PE for mineral-oil services. Always check the specific treaty text rather than assuming a threshold carries over from another country.
Is the 90-day threshold the same in every treaty that has a service PE clause?
No. The India-USA, India-UK and India-Singapore DTAAs all use a 90-day general threshold, but the India-Thailand DTAA sets a single 183-day threshold with no separate related-party limb. The UK and Singapore treaties add a 30-day threshold for associated or related enterprises, while the US treaty's related-enterprise clause has no separate day-count at all.
What happens if there is no DTAA between India and the enterprise's country?
Where no treaty exists, there is no treaty-based service PE test to apply. India instead looks to its domestic "business connection" rule under section 9(9) of the Income-tax Act, 2025 (section 9(1)(i) of the Income-tax Act, 1961), which does not turn on a specific day count but on whether the activity in India amounts to a business connection on the facts.
How is income taxed once a service PE exists?
India taxes the profits attributable to the service PE — the income the PE would have earned had it dealt with the rest of the foreign enterprise at arm's length, the same attribution principle applied in transfer pricing. The foreign enterprise then takes on Indian tax filing and, typically, PAN and withholding obligations on that attributed income.
Can rotating different employees in and out of India avoid a service PE?
No. Treaty service PE clauses count the aggregate days the underlying activity or project continues in India within the relevant period, not the days any one individual employee is present. Multiple employees working in shifts on the same engagement still add up against the same threshold.
