Permanent Establishment and Business Profits (Articles 5 and 7) for CA Final

Updated 5 October 2026 · Fact-checked

A permanent establishment (PE) is a taxable presence of a foreign enterprise in a country under a tax treaty. Under Article 7, the source country taxes business profits only if a PE exists, and only the profits attributable to that PE. Test the PE type first, then attribute profits.

Understand Permanent Establishment and Business Profits

Start with the basic problem. A foreign company sells to customers in India. Should India tax its business profits? Most treaties say no, unless the foreign company has a real, continuing business presence in India. That presence is the permanent establishment (PE).

So the treaty works in two layers. Article 5 defines when a PE exists. Article 7 says the source country can tax business profits of the foreign enterprise only to the extent they are attributable to that PE. No PE means no tax on business profits in the source country. Residence country keeps the right to tax.

Article 5 has four main routes. A fixed place PE needs a place of business, at the enterprise's disposal, with some permanence, through which it carries on its business (office, branch, factory, and so on). A construction PE arises when a building site or installation project lasts beyond the period stated in the treaty. A service PE (found in the UN Model and in many Indian treaties) arises when employees or other personnel furnish services in India for more than the stated days. An agency PE arises when a person acts for the enterprise, habitually concludes contracts or plays the principal role in concluding them, and is dependent.

An independent agent acting in the ordinary course of its own business does not create a PE. A dependent agent acts mainly or wholly for the enterprise and is controlled by it, so it can. Even then, treaties list preparatory or auxiliary activities, such as storage or purchasing goods, which do not create a PE.

The time limits and wording differ from treaty to treaty. In the exam, always use the limit given in the question. Where the treaty is silent or more beneficial, apply the treaty over domestic law, as the assessee may choose the more beneficial of the two. For attribution, treat the PE as a separate and independent enterprise dealing at arm's length, and allow expenses incurred for the PE's purposes.

Key rules to remember

Article 5 general test (fixed place PE)
PE = fixed place of business + at the enterprise's disposal + business carried on wholly or partly through it
All three elements are needed. A mere presence of a few days, or a place with no business activity, may fail the test.
Construction PE
Building site / construction / assembly / installation project continuing for more than the treaty period (commonly 6 or 9 months, or 183 days in some treaties) = PE
Use the period in the specific treaty. Check whether connected projects are aggregated and how the period is counted.
Service PE
Services furnished through employees or other personnel for more than the treaty period (e.g. 90 or 183 days in a given period) = PE
Present in the UN Model and many Indian treaties, not in the OECD Model. Read the treaty's day count and period.
Agency PE
Dependent agent + habitually concludes contracts (or plays principal role in concluding them) on behalf of enterprise = PE
An independent agent acting in the ordinary course of its business does not create a PE. Wording varies across treaties.
Preparatory or auxiliary exclusion
Storage, display, delivery, purchase of goods, or other preparatory or auxiliary activity only = no PE
Check whether the treaty's exclusion list is subject to the 'preparatory or auxiliary' condition.
Article 7 attribution
Taxable profit in source country = profit attributable to the PE, treating PE as a separate and independent enterprise dealing at arm's length
Deduct expenses incurred for the PE's business, including a reasonable share of executive and general administrative expenses, as the treaty permits.
No PE rule
No PE → business profits taxable only in the residence country
Different rules apply to royalties and fees for technical services, which have their own treaty articles.

How to solve Permanent Establishment and Business Profits questions

Use the same order for every case. It keeps you from jumping to profits before proving the PE.

  1. 1Identify the treaty and the two states. Note the enterprise's residence and the source country where the activity occurs.
  2. 2List the facts: place used, who controls it, nature of activity, number of days, who signs contracts, who the agent works for.
  3. 3Test each Article 5 route in turn: fixed place, construction, service, agency.
  4. 4For each route, apply the treaty's time limit or condition to the facts. Count days exactly as the question gives them.
  5. 5Check exclusions: preparatory or auxiliary activity, independent agent status, or a place used only for storage.
  6. 6If there is no PE, conclude that business profits are not taxable in the source country under Article 7.
  7. 7If there is a PE, attribute profit to it as a separate enterprise at arm's length. Allow expenses for the PE's purposes and exclude profits that do not belong to the PE.
  8. 8State the conclusion in provision-facts-conclusion form and mention that the treaty overrides domestic law only where it is more beneficial to the assessee.

Quickest way: Four-question PE check

When to use it: Use this in the MCQ section or when a written answer has limited time.

  1. Is there a place, a project, personnel or an agent in India?
  2. Does the treaty condition (permanence, days, authority to conclude contracts) get met?
  3. Is the activity only preparatory or auxiliary, or is the agent independent?
  4. If PE exists, only the profits attributable to it are taxed in India. If not, nothing is taxed under Article 7.

Common mistakes in Permanent Establishment and Business Profits

  • Taxing all the foreign company's profits in India once a PE exists.

    Students forget that Article 7 limits tax to profits attributable to the PE.

    Fix: Always write 'profits attributable to the PE' and attribute separately, rather than taxing the whole enterprise's profit.

  • Using a day limit from memory instead of the one in the treaty.

    Students remember '183 days' or '6 months' from one treaty and apply it everywhere.

    Fix: Use the limit given in the question. If none is given, state the assumption clearly.

  • Treating every agent as a dependent agent PE.

    Students notice the word agent and skip the independence and authority tests.

    Fix: Check legal and economic dependence, whether the agent acts in the ordinary course of its own business, and whether it concludes contracts or plays the principal role in concluding them.

  • Treating a place with preparatory activity only as a PE.

    Students see a fixed office and stop there.

    Fix: Apply the exclusion for storage, display, delivery, purchasing or other preparatory or auxiliary activity before concluding.

  • Applying service PE in a treaty that has no service PE clause.

    Students assume it exists in all treaties because it appears in the UN Model.

    Fix: Confirm that the treaty contains the service PE clause. Otherwise test other routes only.

  • Disallowing head office expenses while attributing profit to the PE.

    Students ignore the 'separate enterprise' concept.

    Fix: Allow expenses incurred for the PE's business, wherever incurred, including a reasonable share of general administrative costs, subject to treaty and domestic limits.

Worked examples

Example 1

Zenith GmbH, a German company, sends 6 engineers to India to install machinery sold to an Indian customer. The engineers work in India for 150 days in the year. The treaty applied in the question has a service PE clause triggered when services are furnished for more than 183 days in any 12-month period. Zenith has no office in India. Is there a PE in India?

Show the solution
  1. Provision: Under the stated treaty, a service PE arises if employees or personnel furnish services in India for more than 183 days within a 12-month period.
  2. Facts: Services were furnished for 150 days, and there is no office or fixed place.
  3. Test: 150 days does not exceed 183 days, so the service PE test is not met. No fixed place is at Zenith's disposal, so the fixed place PE test also fails.
  4. Check other routes: no agent concludes contracts, so the agency PE does not arise. The installation is incidental to supply, and no other construction or installation PE is described in the facts.

Answer: No PE exists in India on the given facts. Under Article 7, India cannot tax Zenith's business profits from the sale and installation.

Example 2

Alpha Inc., a foreign company, appoints Beta Ltd. in India to sell its products. Beta works only for Alpha, follows Alpha's instructions, and habitually signs sales contracts in Alpha's name. Alpha's total profit from India sales is ₹90,00,000. Alpha shows that ₹30,00,000 of this profit relates to manufacturing done abroad, and the remaining ₹60,00,000 relates to the sales activity in India. Assume the treaty has the standard agency PE clause and the sales activity is attributable to the PE. What is taxable in India?

Show the solution
  1. Provision: A dependent agent who habitually concludes contracts on behalf of the enterprise creates an agency PE.
  2. Facts: Beta works only for Alpha, is controlled by it, and signs contracts in Alpha's name. Beta is therefore a dependent agent.
  3. Conclusion on PE: An agency PE of Alpha exists in India.
  4. Attribution under Article 7: Only profits attributable to the PE are taxable in India. The question states ₹60,00,000 relates to India sales activity and is attributable to the PE.
  5. Exclusion: The ₹30,00,000 relating to foreign manufacturing is not attributable to the PE and is outside India's taxing right.

Answer: Alpha has an agency PE in India through Beta. India can tax ₹60,00,000 attributable to the PE, not the full ₹90,00,000.

Exam tips

  • Write the PE type by name, then quote the condition from the question's treaty extract. Marks go for applying the condition to the facts.
  • Count days carefully. Check whether the treaty uses a 12-month period, a fiscal year or total days.
  • In agent cases, comment separately on dependence, authority to conclude contracts and ordinary course of business.
  • End every PE answer with the Article 7 consequence: profits attributable to the PE only, or no India tax under Article 7 if no PE.
  • In MCQs, look for traps such as storage-only premises, independent brokers or a project one day short of the limit.

Permanent Establishment and Business Profits: frequently asked questions

What is a permanent establishment under Article 5?

It is a fixed place of business through which an enterprise carries on its business, and it also includes certain projects, services and dependent agents. It decides whether the source country can tax the business profits of a foreign enterprise.

What is the difference between a dependent and an independent agent PE?

A dependent agent acts mainly or wholly for the enterprise and is controlled by it, so it can create an agency PE if it habitually concludes contracts. An independent agent acting in the ordinary course of its own business does not create a PE.

Is 183 days the rule for construction PE in all treaties?

No. The period is set by each treaty and may be, for example, 6 months, 9 months or 183 days. Always use the period stated in the treaty given in the question.

How are profits attributed to a PE under Article 7?

The PE is treated as a separate and independent enterprise dealing at arm's length with the head office. Only the profits attributable to the PE are taxed in the source country, after allowing expenses incurred for the PE's business.
