What Is Profit Attribution to a Permanent Establishment?
Having a Permanent Establishment (PE) in India answers only the first question a foreign company faces: is any of my profit taxable here at all? Profit attribution answers the harder second question: how much? A foreign enterprise runs one global business with one set of worldwide profits. Once part of that business is carried on through a fixed place, project, service team, or dependent agent in India, Indian tax law needs a rule for splitting off the slice of profit that belongs to the Indian operation. That splitting rule — not the existence test — is where most of the real tax exposure and the real disputes sit.
Profit attribution is not the same exercise as transfer pricing between related companies. Transfer pricing prices transactions between two separate legal persons — an Indian subsidiary and its foreign parent, say — under sections 92 to 92F of the Income-tax Act, 1961 (sections 161 to 173 of the Income-tax Act, 2025). A PE is not a separate legal person; it is the same non-resident enterprise operating partly inside India and partly outside it. Attribution asks how much of that single enterprise's own profit its Indian "part" would have earned had it stood alone. Both exercises borrow the same underlying yardstick — pricing as an independent party would — but they run under different provisions, and conflating them is a common and consequential mistake.
Legal Basis
Domestic Law — Section 9(9)(f) of the Income-tax Act, 2025
India's domestic attribution rule sits inside the same provision that defines business connection. Section 9(9)(f) of the Income-tax Act, 2025 (Explanation 1(a) to section 9(1)(i) of the Income-tax Act, 1961) provides that where all the operations of a business are not carried out in India, "only the income which is reasonably attributable to operations carried out in India... shall be deemed to accrue or arise in India from any business connection." This is the domestic-law starting point: India taxes only the India-sourced slice, not the non-resident's entire global profit. The same sub-clause extends the principle to income from a significant economic presence under section 9(9)(d).
DTAAs — Article 7
Where a Double Taxation Avoidance Agreement applies, its business-profits article — Article 7 in nearly every Indian treaty — governs instead of, or alongside, domestic law. Article 7(2) of the India-US DTAA states the core rule: profits attributed to a PE are "the profits which it might be expected to make if it were a distinct and independent enterprise engaged in the same or similar activities under the same or similar conditions and dealing wholly at arm's length with the enterprise of which it is a permanent establishment." This is the same arm's length language that anchors arm's length pricing in ordinary transfer pricing — but here it is applied notionally, splitting one enterprise into a hypothetical independent PE and a hypothetical independent head office. Article 7(3) then fixes what the PE may deduct in arriving at that profit: "expenses which are incurred for the purposes of the business of the permanent establishment, including a reasonable allocation of executive and general administrative expenses, research and development expenses, interest, and other expenses incurred for the purposes of the enterprise as a whole." Where a treaty is in force, the treaty's arm's length standard prevails over the domestic-law wording by virtue of the treaty-more-beneficial rule at section 159(4) of the Income-tax Act, 2025 (section 90(2) of the Income-tax Act, 1961).
Rule 10 of the Income-tax Rules — The Computational Machinery
Neither section 9 nor Article 7 tells an Assessing Officer how to actually calculate a number. That job falls to Rule 10 of the Income-tax Rules, 1962, headed "Determination of income in the case of non-residents", which applies wherever the Assessing Officer is of opinion that the actual amount of the non-resident's Indian income "cannot be definitely ascertained" — the everyday situation for a PE, which rarely keeps a clean, separate set of books. Rule 10 gives the Assessing Officer three alternative methods: income "at such percentage of the turnover so accruing or arising as the Assessing Officer may consider to be reasonable"; an amount bearing the same proportion to the total profits and gains of that person's business as the receipts arising in India bear to the total receipts of the business; or, as a third alternative, income computed "in such other manner as the Assessing Officer may deem suitable." In practice this third, open-ended limb is what keeps Rule 10 alive: it lets officers reach for a functions-assets-risks (FAR) analysis of the PE's own activities — mirroring the FAR analysis used in ordinary transfer pricing — instead of a mechanical percentage. Rule 10 remains the operative computational tool even where a DTAA applies: the treaty fixes the standard (arm's length, distinct-and-independent-enterprise), but domestic procedure still supplies the mechanics for estimating the number.
The Income-tax Rules, 2026 took effect on 1 April 2026, the same date as the Income-tax Act, 2025, and the department's own rules index lists a Rule 9 under the heading "Determination of income in case of non-residents". Only that heading has been confirmed; the restated text of Rule 9 has not been read here, so it should be checked directly before relying on any procedural specific for a tax year beginning on or after 1 April 2026. For any earlier year, the 1962 Rule 10 wording is what governs.
The CBDT's 2019 Draft Report — Proposed, Never Adopted
Rule 10's open texture — three loosely defined methods and heavy officer discretion — has long been criticised as unpredictable, and it is a leading source of PE-related tax disputes in India. On 18 April 2019, the CBDT released a Committee report proposing to replace Rule 10's discretion with a fixed fractional-apportionment formula, and invited stakeholders to send comments "within 30 days of the publication" of the report.
That report is a draft that was never enacted. No notification has since amended Rule 10 to adopt a fixed formula; it still carries the same open, three-method, officer-discretion structure the 2019 Committee was convened to replace. Any claim that India taxes PE profit using a formal apportionment formula is describing a 2019 proposal, not current law, and should be labelled as such.
Why This Matters for Foreign Companies
For a foreign company, the attribution rule is where the tax bill actually gets set. Two companies with an identical PE trigger — say, the same 10-month consulting engagement in Bangalore — can end up with very different Indian tax liabilities depending on which of Rule 10's three methods the Assessing Officer applies, how expenses are allocated under Article 7(3), and how well the PE's own functions, assets, and risks are documented. Because the standard leans on discretion rather than a fixed formula, the burden falls on the taxpayer to build a defensible FAR analysis, keep management accounts that isolate the PE's own activity, and be ready to argue the attribution number rather than simply the existence of a PE. Attributed profit is taxed at the rate applicable to a foreign company under the Finance Act for the relevant year, plus applicable surcharge and health and education cess — materially higher than the rate available to an Indian-incorporated subsidiary, which is one of the strongest reasons foreign investors choose to incorporate locally rather than operate through an unstructured PE.
Practical Example
A German engineering firm sends a project team to install equipment at a client site in India for 11 months, creating a construction/installation PE under the relevant DTAA. The firm has no separate Indian entity and keeps no standalone accounts for the Indian project — only consolidated global accounts. Because the true India-attributable profit cannot be read off the firm's books, the Assessing Officer turns to Rule 10. Rather than apply a flat percentage of the project's Indian turnover, the officer requests a FAR analysis: which functions (engineering design, on-site installation, project management), assets (specialised equipment, technical know-how) and risks (defect liability, currency risk) sit with the Indian PE versus the German head office. Based on that analysis, a proportion of the project's total profit — reflecting the PE's own contribution — is attributed to India and taxed under Article 7(2) of the applicable DTAA, with head-office expense allocations reduced under Article 7(3) for costs properly borne overseas.
Common Mistakes
- Treating attribution and transfer pricing as the same exercise. Attribution splits one enterprise's own profit between its home country and its PE; transfer pricing prices transactions between two separate legal entities. Applying section 92-92F transfer pricing methods directly to a PE without checking whether Rule 10 or Article 7 actually requires it is a frequent error.
- Assuming a fixed formula exists. The CBDT's 2019 report proposed one; it was never adopted. Rule 10 still runs on officer discretion across three open methods.
- Ignoring Article 7(3) deductions. A PE is entitled to a reasonable allocation of head-office administrative, R&D, and interest expenses in arriving at its attributable profit — many foreign companies under-claim this and overstate their own Indian tax liability.
- Keeping no separate PE accounts. Without management accounts that isolate the PE's own functions, assets, and risks, the taxpayer cedes the attribution argument entirely to the Assessing Officer's discretion under Rule 10's third, catch-all method.
Frequently Asked Questions
Is profit attribution the same as transfer pricing?
No. Transfer pricing under sections 92-92F of the Income-tax Act, 1961 (sections 161-173 of the Income-tax Act, 2025) prices transactions between two separate legal entities. Profit attribution splits one non-resident enterprise's own worldwide profit between its foreign head office and its Indian permanent establishment. Both use an arm's length yardstick, but they are legally distinct exercises with different governing provisions.
Which rule actually decides how much profit gets attributed to my PE?
Rule 10 of the Income-tax Rules, 1962 gives the Assessing Officer three methods: a reasonable percentage of the turnover arising in India, an amount bearing the same proportion to the business's total profits as its Indian receipts bear to its total receipts, or any other manner the officer considers suitable — typically a functions-assets-risks analysis of the PE's own activity. The Income-tax Rules, 2026 list a Rule 9 under the same heading from 1 April 2026; check its restated text before relying on it for a later year.
Did the 2019 CBDT report change how PE profit is taxed today?
No. The Committee's report of 18 April 2019 proposed replacing Rule 10 with a fixed fractional-apportionment formula and was opened for stakeholder comment for 30 days. It was never notified into law. Rule 10 still applies the original three-method, discretion-based approach.
Does the DTAA or Indian domestic law control attribution?
Where a Double Taxation Avoidance Agreement applies, its Article 7 arm's length standard prevails over the domestic-law wording under the treaty-more-beneficial rule. In practice, Assessing Officers still use Rule 10's computational methods to arrive at the actual figure, since neither the treaty nor domestic law specifies a calculation mechanic on its own.
Can I reduce my PE's attributed profit by claiming head-office costs?
Yes, where a DTAA applies. Article 7(3) of most Indian treaties allows the PE to deduct a reasonable allocation of executive, general administrative, research and development, and interest expenses incurred for the enterprise as a whole, not only costs incurred locally in India.
