What Is a Construction and Installation Permanent Establishment?
A Construction and Installation Permanent Establishment (PE) is a category of Permanent Establishment that arises when a foreign enterprise runs a building site, or a construction, installation, or assembly project, or supervisory activities connected to one, in India for longer than the duration fixed by the applicable tax treaty. Once that duration is crossed, India taxes the profits the site or project earned as if the foreign company had a taxable establishment here, even though the company registered no branch, subsidiary, or office to do the work.
The concept exists because construction and installation work is, by nature, temporary. Most Indian double taxation avoidance agreements (DTAAs) carve construction activity out of the general "fixed place of business" test in Article 5(1) and give it its own duration-based rule in Article 5(2), so that short jobs stay outside PE status while long-running ones do not.
Legal Basis
Income-tax Act — Sections 9(2)(c), 9(9) and 173(c)
Domestic law does not carve out a separate definition for construction or installation PE. Under section 9(2)(c) of the Income-tax Act, 2025 (section 9(1)(i) of the Income-tax Act, 1961), income arising through a "business connection" in India is deemed to accrue in India, and section 9(9) defines business connection broadly enough to capture a construction site. "Permanent establishment" is itself defined only in outline at section 173(c) of the Income-tax Act, 2025 (section 92F(iiia) of the Income-tax Act, 1961) as "a fixed place of business through which the business of the enterprise is wholly or partly carried on." For the specific duration test that turns a site into a PE, domestic law relies on the applicable DTAA.
DTAAs — Article 5(2) Duration Thresholds
Every Indian DTAA that follows the OECD or UN Model places construction and installation PE inside Article 5(2), alongside fixed places such as offices and factories. The wording is close to standard — "a building site or construction, installation or assembly project or supervisory activities in connection therewith" — but the duration that must be crossed, and whether "installation" is named at all, differs treaty by treaty. The table below quotes each threshold directly from the treaty text.
| DTAA | Article | Threshold | Treaty wording |
|---|---|---|---|
| India-USA | 5(2)(k) | 120 days | "continue for a period of more than 120 days in any twelve-month period" |
| India-UK | 5(2)(j) | Six months | "continues for a period of more than six months" |
| India-Germany | 5(2)(i) | Six months | "continue for a period exceeding six months" |
| India-Austria | 5(2)(i) | Six months | "continue for a period of more than six months," aggregating "the same or connected project, site or activities" |
| India-Vietnam | 5(2)(h) | Six months | "continues for a period of more than six months" — no "installation" limb |
The India-US treaty is the outlier: at 120 days it sets one of the shortest construction-PE thresholds in India's treaty network, and it counts in a rolling twelve-month period rather than a single project's lifetime. The India-Vietnam treaty is worth flagging on wording, not duration: Article 5(2)(h) covers "a building site or construction or assembly project or supervisory activities," but never uses the word "installation" — a pure installation contract, with no construction or assembly element, sits outside this specific limb, though it may still be tested under other Article 5 provisions.
How the Duration Threshold Is Counted
The count runs against the site, project, or supervisory activity itself, not against any one employee's days present in India. Two features recur across the treaties above. First, the threshold is tested over a defined window — the India-US treaty uses "any twelve-month period" rather than a fixed calendar or financial year, so the twelve months can start on any date and the test can be met partway through a longer engagement. Second, several treaties aggregate connected work: the India-US treaty counts a site or project "together with other such sites, projects or activities, if any," and the India-Austria treaty aggregates "the same or connected project, site or activities." A foreign enterprise cannot reset the clock by rotating which of its own contracts or affiliated entities is nominally responsible for the site if the underlying work is connected.
The MLI Overlay — Article 14 Splitting-of-Contracts
The OECD/G20 Base Erosion and Profit Shifting Multilateral Instrument (MLI) contains a further anti-avoidance rule at Article 14, aimed at closely related enterprises that split a single construction or installation project into several shorter contracts, each falling under a treaty's threshold on its own. Where it applies, Article 14 aggregates the time spent by connected enterprises on connected activities at the same site so the combined period is tested against the threshold. But the MLI only modifies a specific tax treaty — a "Covered Tax Agreement" — where both treaty partners accepted Article 14 for that pair, and several of India's partners did not. India's official synthesised text for the India-Austria DTAA, published by the Income Tax Department, applies the Principal Purpose Test and the Article 13 specific-activity/anti-fragmentation rule to Article 5, but Article 14 is absent from it — confirming the MLI does not modify that treaty's construction-PE threshold. The India-Japan synthesised text is the same in this respect: it applies MLI Articles 4, 6, 7, 9, 10, 12, 13, 15 and 17, with no Article 14. For both treaties, the original treaty-text threshold stands with no MLI contract-splitting overlay layered on top.
Presumptive Taxation for Turnkey Power Project Contractors
A foreign company whose construction PE arises from civil construction, erection, testing, or commissioning of plant or machinery in connection with a turnkey power project approved by the Central Government can elect presumptive taxation under section 61(2) (Table, Sl. No. 4) of the Income-tax Act, 2025 (section 44BBB of the Income-tax Act, 1961). Under this route, 10% of the amount paid or payable for the construction, erection, testing, or commissioning work — whether received in India or outside it — is deemed to be the taxable profit, regardless of the contractor's actual margin. Section 61(3) lets a contractor instead claim a lower actual profit, but only if it keeps books of account under section 62 and has them audited under section 63. Contractors outside this narrow turnkey-power-project category are assessed on their actual PE profits under the general provisions.
Why a Construction PE Matters for Foreign Contractors and Investors
Once a site or project crosses its treaty threshold, three consequences follow. First, India taxes the profits attributable to the PE — for a foreign company, at the standard foreign-company rate of 35% (plus surcharge and cess), unless the section 61(2) presumptive route for turnkey power projects applies. Second, payments to the contractor become subject to withholding: tax must be deducted at source on remittances to non-residents under section 393(2) (Table, Sl. No. 17) of the Income-tax Act, 2025 (section 195 of the Income-tax Act, 1961), at rates in force, unless a lower or nil-deduction certificate under section 395 is obtained. Third, the foreign company must obtain a PAN and file an Indian income tax return for the profits attributable to the site — and, to claim treaty relief at all, must furnish a Tax Residency Certificate along with Form 41.
Foreign construction and engineering contractors often assume that operating without an Indian entity avoids Indian tax exposure. A project office registered with a FEMA-authorized dealer bank for the specific contract is usually the cleaner structure: it gives the contractor a recognized local presence for banking, customs, and GST purposes, without changing the underlying PE analysis, which still turns on the treaty's duration test.
Common Mistakes
- Using one treaty's threshold as if it were universal. 120 days under the India-US treaty is not six months under the India-UK, India-Germany, or India-Austria treaties. Always check the specific Article 5(2) wording of the treaty that applies to the contractor's home country.
- Assuming the MLI automatically aggregates split contracts. Article 14 of the MLI only aggregates connected contracts where both treaty partners accepted it. India's treaties with Austria and Japan are confirmed exceptions — the base treaty threshold applies with no MLI splitting overlay.
- Treating "installation" as always covered. The India-Vietnam treaty's construction-PE limb, Article 5(2)(h), does not use the word "installation" at all — a pure installation contract needs a different Article 5 test.
- Ignoring built-in aggregation wording. Several treaties, including India-US and India-Austria, count connected sites, projects, or activities together in their base text — restructuring a single job into several nominally separate contracts does not reset the clock.
- Missing the presumptive-tax election. A turnkey power project contractor who does not elect section 61(2) treatment, and does not maintain audited books to support a lower actual profit under section 61(3), risks a full profit-attribution assessment with a heavier compliance burden.
Practical Example
A US engineering firm wins a contract to build and commission a factory assembly line near Pune. Its own personnel are on site for five months; a related affiliate then takes over supervisory work on the same line for a further two months. Measured separately, neither company's presence exceeds 120 days. But Article 5(2)(k) of the India-US DTAA counts connected sites, projects, and activities "together," so the combined seven-month presence exceeds the 120-day threshold within the twelve-month period, and a construction PE arises. The firm must obtain a PAN, and the profits attributable to the site are taxed at 35%. Had the same combined project instead run for an Austrian contractor, no MLI contract-splitting rule would have been needed to reach the same result — the India-Austria treaty's own Article 5(2)(i) wording already aggregates "the same or connected project, site or activities" once the six-month threshold is crossed.
Frequently Asked Questions
Does a construction PE apply to installation-only contracts?
It depends on the treaty. Most Indian DTAAs, including India-USA, India-UK, and India-Germany, expressly include "installation" projects alongside construction and assembly in their Article 5(2) construction-PE limb. The India-Vietnam treaty is a notable exception — its Article 5(2)(h) covers only a "construction or assembly project," so a pure installation contract may need to be tested under a different Article 5 provision instead.
Is the 120-day India-US threshold measured per contract or per company?
Neither, strictly. Article 5(2)(k) of the India-US DTAA aggregates: the site, project, or activities are counted "together with other such sites, projects or activities, if any," within the same twelve-month period. The test looks at the enterprise's connected construction presence in India as a whole, not any single standalone contract.
Does the BEPS Multilateral Instrument change every Indian construction-PE threshold?
No. The MLI's Article 14 contract-splitting rule modifies a treaty only where both India and the treaty partner accepted it for that Covered Tax Agreement. India's official synthesised texts for its treaties with Austria and Japan do not include Article 14 among the applicable modifications, so those two treaties' construction-PE thresholds run on the original treaty wording alone.
What happens once a construction PE is confirmed?
The foreign company must obtain a PAN and file an Indian income tax return for profits attributable to the site. Those profits are taxed at the standard foreign-company rate unless the section 61(2) presumptive-taxation election for turnkey power projects applies, and payments to the contractor remain subject to withholding under section 393(2) of the Income-tax Act, 2025 at rates in force.
Can a foreign contractor avoid a construction PE by using a local project office?
Registering a project office through a FEMA-authorized dealer bank gives a foreign contractor a recognized local presence for banking and compliance, but it does not by itself change the PE analysis. Whether a construction PE exists still turns on how long the site, project, or supervisory activity runs, measured against the applicable treaty's Article 5(2) threshold.
