Residence, Permanent Establishment and Tie-Breaker Rules under DTAA

Updated 11 October 2026 · Fact-checked

A treaty applies only to a person who is a resident of a contracting state. If two states both treat a person as resident, tie-breaker tests decide one state. A permanent establishment (PE) is a fixed place, dependent agent or service presence through which a foreign enterprise does business, and it lets the source state tax business profits.

Understand Residence, Permanent Establishment and Tie-Breaker Rules

A tax treaty (DTAA) applies to "persons who are residents of one or both contracting states". So the first question is always: who is a resident, and of which state? Each country defines residence in its own law. Under the Income-tax Act, 2025, section 6 sets the Indian test.

For an individual, section 6(2) makes you resident in India if you stay 182 days or more in the tax year, or 60 days or more in the year and 365 days or more in the four preceding years. A company is resident if it is an Indian company or its place of effective management (POEM) is in India. POEM means the place where key management and commercial decisions needed for the business as a whole are, in substance, made (section 6(10)). Other persons are resident unless control and management is wholly outside India.

Problem: two countries can each call the same person resident. That is dual residence, and it brings double taxation. Most treaties, following the OECD and UN models, solve this with a tie-breaker. For an individual the tests apply in order: permanent home available; centre of vital interests (personal and economic ties); habitual abode; nationality; and finally mutual agreement of the two states. Move to the next test only if the earlier one does not settle the matter. For a non-individual, many treaties use the place of effective management. Some newer treaties instead require the authorities to settle it by mutual agreement. Always read the actual treaty article.

Next, business profits. Under the usual treaty rule, the profits of a foreign enterprise are taxed only in its home state, unless it carries on business in the other state through a permanent establishment. Then the other state may tax only the profits attributable to that PE.

A PE has several types. A fixed place PE is a place of business such as an office, branch, factory or mine, with some degree of permanence, at the enterprise's disposal, through which business is carried on. A construction or installation PE arises if a project lasts longer than the treaty period. A service PE (found in many Indian treaties) arises when employees or other personnel render services in India for more than the stated days. A dependent agent PE arises when a person habitually concludes contracts or plays the principal role in concluding them for the enterprise. An independent agent acting in the ordinary course of its own business does not create one. Preparatory or auxiliary activities, such as storage or purchasing, are usually excluded.

Key rules to remember

Individual resident test (domestic): Resident if India stay ≥ 182 days in the tax year, OR ≥ 60 days in the year AND ≥ 365 days in the preceding 4 years; Section 6(2). The 60-day limit becomes 120 days for a citizen or person of Indian origin visiting India with Indian-source income above ₹15 lakh (section 6(4) and (5)).
Company resident (domestic): Resident if Indian company OR place of effective management in India; Section 6(10). POEM means where key management and commercial decisions for the business as a whole are, in substance, made.
Individual tie-breaker order: Permanent home → centre of vital interests → habitual abode → nationality → mutual agreement; Typical OECD-style order. Apply in sequence and stop at the first test that gives a single state. Check the exact treaty wording.
Non-individual tie-breaker: Place of effective management (or mutual agreement in some treaties); Treaty-specific. Do not assume POEM always applies.
Business profits rule: Business profits taxable in the source state only if there is a PE, and only to the extent attributable to that PE; Applies when the enterprise is resident in the other contracting state.
Types of PE: Fixed place PE; construction or installation PE; service PE; dependent agent PE; Each has its own conditions. Service PE and construction PE depend on duration thresholds fixed in the treaty.

How to solve Residence, Permanent Establishment and Tie-Breaker Rules questions

Use this order for any case question on treaty residence or PE. Write provision, facts, conclusion.

1Identify the person (individual, company, firm) and the two countries involved. Name the treaty.
2Test residence under each country's domestic law. For India, apply section 6 of the Income-tax Act, 2025 with day counts or POEM.
3If only one country treats the person as resident, the treaty is available to that person. Stop the tie-breaker there.
4If both treat the person as resident, apply the treaty tie-breaker in order. For an individual, go from permanent home down to mutual agreement. For a company, use POEM or the treaty's mutual agreement clause.
5State which country is the treaty resident and the effect: the other country becomes the source state and its taxing rights are limited by the treaty.
6For business income, ask whether a PE exists in the source state. Check the type: fixed place, construction, service or dependent agent. Compare the facts with the treaty threshold.
7If a PE exists, limit taxation to profits attributable to it. If none, business profits are taxable only in the residence state.
8Write a one-line conclusion with the tax consequence.

Quickest way: Two-gate shortcut: resident first, PE second

When to use it: Use this when time is short and the question gives facts such as days stayed, family location or an agent's activity.

Count days and apply the 182 and 60/365 tests. Mark each country resident or not.
If dual resident, list the facts under the headings: home, family and economic ties, habitual abode, nationality. Go down the list until one country wins.
For a company, note where the board meets and decides strategy. That is usually the POEM.
For PE, tick one box: place of business, project duration, services days, or agent who concludes contracts.
Compare with the threshold in the question. Conclude in one sentence.

Common mistakes in Residence, Permanent Establishment and Tie-Breaker Rules

Applying the tie-breaker when only one country treats the person as resident.
Students memorise the tests and apply them mechanically.
Fix: First check dual residence. The tie-breaker is only needed when both states claim the person as resident.
Jumping to nationality before checking permanent home and vital interests.
Nationality feels like the simplest fact.
Fix: Follow the order. Nationality is the fourth test, used only if the first three do not settle it.
Treating the domestic POEM definition as the treaty tie-breaker for every company.
Both use the phrase place of effective management.
Fix: Section 6(10) decides residence under Indian law. The treaty tie-breaker applies only for dual residence and its wording differs across treaties. Read the article.
Saying any agent creates a dependent agent PE.
Students ignore the authority to conclude contracts.
Fix: Check whether the agent habitually concludes contracts or plays the principal role in doing so. An independent agent acting in its ordinary course does not create a PE.
Taxing the entire profit of the foreign enterprise once a PE exists.
Confusing PE existence with the extent of taxation.
Fix: Only profits attributable to the PE are taxable in the source state.
Quoting 182 days as the only residence test.
It is the best known limb of section 6(2).
Fix: State both limbs of section 6(2) and mention the 120-day variation in section 6(5) where facts involve a visiting citizen or person of Indian origin.

Worked examples

Example 1

Mr Rao, an Indian citizen, lives with his family in Pune and owns a house there. In the tax year he stays 190 days in Country X on a work assignment and stays in a rented flat. Country X treats him as resident on its 183-day rule. Country X's treaty with India has the standard OECD-style tie-breaker. Decide his treaty residence.

Show the solution

Under India's law: he is in India for 175 days (365 − 190) if the year has 365 days. That is below 182. Check the second limb. Section 6(2)(b) needs 60 days or more in the year and 365 days or more in the four preceding years. Assume the facts show he was in India more than 365 days in those four years. He is then resident in India. Country X also treats him as resident. So there is dual residence.
Apply the tie-breaker. Test 1, permanent home: he has a home in Pune available to him. In Country X he has only a rented flat for the assignment, which is not a permanent home in the same sense. Assume the facts give the Pune home as his permanent home.
Since only India gives a permanent home, the tie is resolved at the first test. No further tests are needed.

Answer: Mr Rao is a treaty resident of India. Country X becomes the source state for the income there and its taxing rights are limited by the treaty.

Example 2

Alpha Inc., a company resident in Country Y, has no office in India. It appoints Mr Sharma, an Indian, to sell its goods in India. Mr Sharma habitually negotiates and signs contracts on behalf of Alpha Inc. and works only for Alpha Inc. Does Alpha Inc. have a PE in India? Would your answer change if Mr Sharma were an independent broker serving many principals in the ordinary course of his business?

Show the solution

Alpha Inc. is a non-resident enterprise. Its business profits are taxable in India under the treaty only if it has a PE in India.
There is no fixed office. Check for a dependent agent PE. The test is whether the agent habitually concludes contracts on behalf of the enterprise.
Mr Sharma habitually signs contracts for Alpha Inc. and works only for it, so he is dependent on it. A dependent agent PE exists.
Only the profits attributable to this PE are taxable in India.
If Mr Sharma were an independent broker acting in the ordinary course of his own business for many principals, the independent agent exception applies. No PE arises on that ground, and Alpha Inc.'s business profits stay taxable only in Country Y.

Answer: Yes, Alpha Inc. has a dependent agent PE in India, and India may tax only the profits attributable to it. If Mr Sharma were a true independent broker, there would be no PE.

Exam tips

Write the section 6 limbs exactly: 182 days, or 60 days plus 365 days in four years. Examiners reward the correct numbers.
In a dual residence question, list the tie-breaker tests in order and show which one decides the case. Do not skip steps.
For PE questions, name the type of PE first, then match the facts against the threshold in the treaty. If the threshold is not given, say it depends on the treaty.
Always end with a conclusion on which state may tax and to what extent. Case-based papers award marks for the conclusion.
Say "subject to the specific treaty" when you rely on a general OECD or UN rule.

Residence, Permanent Establishment and Tie-Breaker Rules: frequently asked questions

What is the tie-breaker rule in a DTAA?

It is a set of tests in the residence article that decides which one country is the treaty resident when both treat a person as resident. For an individual the order is permanent home, centre of vital interests, habitual abode, nationality, then mutual agreement.

How is the treaty residence of a company decided?

First check residence under each country's law. Under India's law a company is resident if it is an Indian company or its place of effective management is in India. If both countries claim it, the treaty tie-breaker applies, often place of effective management or mutual agreement.

What is a service PE?

It arises when an enterprise furnishes services in the other country through employees or other personnel for more than the number of days stated in the treaty. It is not found in every treaty, so check the article.

What is a dependent agent PE?

It arises when a person acting for a foreign enterprise habitually concludes contracts for it, or plays the principal role in concluding them. An independent agent acting in the ordinary course of its own business does not create it.
