Key DTAA Treaty Articles and Tie-Breaker Rules

Updated 11 October 2026 · Fact-checked

A DTAA divides taxing rights between two countries. You solve a question by finding the person's treaty residence (using the tie-breaker tests if both countries claim them), then the income's article, then checking for a permanent establishment and the treaty rate or method. Apply the treaty only where it helps the assessee.

Understand Key Treaty Articles and Tie-Breaker Rules

A Double Taxation Avoidance Agreement (DTAA) is a treaty between two countries. It stops the same income being taxed fully in both. It does this by deciding which country may tax which income, and by how much.

Most treaties follow the OECD or UN model. Each type of income has its own article. The common ones are residence (Article 4), permanent establishment (Article 5), business profits (Article 7), royalties and fees for technical services (Articles 12 or 12/13, numbering varies by treaty), and capital gains (Article 13 in many treaties). Always read the actual article numbers in the treaty given in the question.

Residence and the tie-breaker. A treaty applies to a person who is a resident of one or both countries. A person can be a resident of both under the domestic laws of each country. The tie-breaker tests then decide a single treaty residence. For an individual, the usual order is: (1) permanent home available; (2) centre of vital interests, meaning closer personal and economic ties; (3) habitual abode; (4) nationality; (5) if still unresolved, mutual agreement of the two countries. Move to the next test only if the earlier one does not settle it. For a company or other non-individual, many treaties use the place of effective management, though some use place of incorporation or mutual agreement. Check the treaty.

Permanent establishment (PE). A PE is generally a fixed place of business through which a foreign enterprise carries on its business, such as a branch, office, factory or workshop. Many treaties also treat a building site or installation project as a PE only if it lasts beyond a stated period, and treat a dependent agent who habitually concludes contracts as a PE. Preparatory or auxiliary activities, such as storage or purchasing, are usually excluded. Business profits of a foreign enterprise are taxable in the other country only to the extent attributable to the PE there.

Royalty and fees for technical services. Treaties usually let the source country tax these at a limited rate, often a capped percentage of gross receipts. But if the recipient has a PE in the source country and the right or contract is effectively connected with it, the income is treated as business profits instead. The Income-tax Act, 2025 reflects this in section 59. Income of a non-resident (not a company) or a foreign company in the nature of royalty or fees for technical services is computed under the head "Profits and gains of business or profession" when four conditions are met: it is received from the Government or an Indian concern; it is under an agreement with them; the assessee carries on business through a PE, or performs professional services from a fixed place of profession, in India; and the right, property or contract is effectively connected with that PE or fixed place.

Capital gains. Treaties allocate the right to tax by asset type. Gains on immovable property are generally taxable where the property is. Gains on movable property forming part of a PE's business property are taxable where the PE is. Gains on shares or other assets are often taxable in the seller's country of residence, subject to what the specific treaty says.

Key rules to remember

Tie-breaker order for individuals: Permanent home → Centre of vital interests → Habitual abode → Nationality → Mutual agreement; Apply in sequence. Stop at the first test that gives a single answer. Confirm the order in the treaty given.
Business profits rule: Taxable in source country only if profits are attributable to a PE there; No PE normally means business profits are taxable only in the residence country.
Section 59(1) conditions (all four needed): Received from Government/Indian concern + under an agreement + PE or fixed place of profession in India + right/contract effectively connected with it; If met, royalty or FTS of a specified assessee is computed as business profits.
Specified assessee (section 59(5)): Non-resident (not a company) or a foreign company; Residents and domestic companies are outside this section.
Deductions barred under section 59(2): No deduction for (a) expenditure not wholly and exclusively incurred for the PE/fixed place business; (b) amounts paid to head office or other offices, other than reimbursement of actual expenses; Notional internal royalty or interest to the head office is not allowed.
Section 59(4) compliance: Maintain books per section 62, get accounts audited by the specified date under section 63, furnish the audit report; This compliance applies to income computed under section 59(1).
Treaty or domestic law: Tax liability = the more beneficial of treaty and domestic provisions; The treaty applies to the extent it is more beneficial to the assessee, not otherwise.

How to solve Key Treaty Articles and Tie-Breaker Rules questions

Use this order for any DTAA question. It stops you from jumping to a rate before checking who is entitled to the treaty.

1Identify the two countries, the person (individual, company, other) and the nature of the income.
2Decide residence under each country's domestic law. If the person is a resident of only one, that country is the treaty residence.
3If resident of both, apply the tie-breaker tests in order and stop at the first decisive one. Write the reason for each test.
4Pick the article for the income: business profits, royalty/FTS, capital gains, and so on.
5Check for a PE in the source country. If there is one and the income is effectively connected with it, treat the income as business profits, with attribution to the PE.
6Apply the treaty rate or method, and compare with the domestic rate. Take the beneficial one.
7Compute the tax, then state the relief method (exemption or credit) for the residence country.
8Write a one-line conclusion naming the country that may tax and the article relied on.

Quickest way: Four-question screen

When to use it: Use for MCQs and for short parts of a long answer when time is tight.

Is the person a resident of both? If not, skip the tie-breaker.
If yes, ask in order: home, vital interests, habitual abode, nationality. The first clear answer wins.
Does the non-resident have a PE or fixed place in the source country? No PE usually means no tax on business profits there.
For royalty or FTS, check effective connection with a PE. If connected, it is business profits under section 59, not a capped-rate receipt.

Common mistakes in Key Treaty Articles and Tie-Breaker Rules

Applying the tie-breaker when the person is a resident of only one country.
Students see two countries and assume dual residence.
Fix: First test residence under domestic law of each country. The tie-breaker applies only if both claim residence.
Jumping to nationality as the first test.
Nationality feels like the obvious link.
Fix: Nationality is fourth. Start with permanent home and centre of vital interests.
Taxing royalty at the treaty rate when the recipient has an effectively connected PE.
Students memorise the rate and skip the PE check.
Fix: If the section 59 conditions are met, compute it as business profits, after the disallowances in section 59(2).
Allowing payments to the head office as a deduction while computing PE income.
These look like normal business expenses.
Fix: Under section 59(2)(b), payments to the head office or other offices are not allowed, except reimbursement of actual expenses.
Treating every office or storage space as a PE.
The word fixed place is read too loosely.
Fix: Check the exclusions for preparatory or auxiliary activities and any time threshold for construction sites in the treaty.
Applying the treaty even when domestic law is lower.
Students assume treaty always overrides.
Fix: Apply the treaty only to the extent it is more beneficial to the assessee.

Worked examples

Example 1

Mr. Arjun, an Indian citizen, is a resident of both India and Country X under their domestic laws. He has a permanent home available in both countries. His family and his main business are in India. He works in X for a two-year contract. Determine his treaty residence.

Show the solution

He is a resident of both countries, so the tie-breaker is needed.
Test 1, permanent home: available in both, so it is not decisive.
Test 2, centre of vital interests: family and main business are in India, so personal and economic ties are closer to India.
This test gives a single answer, so there is no need to go to habitual abode or nationality.

Answer: Mr. Arjun is treated as a resident of India for treaty purposes, under the centre of vital interests test.

Example 2

Alpha Inc., a foreign company with a PE in India, receives ₹40,00,000 from an Indian concern under an agreement for technical services. The contract is effectively connected with the Indian PE. Alpha also claims ₹6,00,000 as a deduction for an internal charge paid to its head office (not a reimbursement of actual expenses) and ₹4,00,000 of direct expenses wholly and exclusively for the PE business. Compute the income under section 59.

Show the solution

Alpha Inc. is a foreign company, so it is a specified assessee under section 59(5).
All four conditions in section 59(1) are met, so the fees are computed as business profits.
Deduction for direct expenses wholly and exclusively for the PE business: allowed, ₹4,00,000.
Deduction for the internal head office charge: barred by section 59(2)(b), so ₹0.
Income = ₹40,00,000 − ₹4,00,000 = ₹36,00,000.
Alpha must maintain books, get accounts audited and furnish the audit report as per section 59(4).

Answer: Income computed under the head Profits and gains of business or profession is ₹36,00,000. The ₹6,00,000 head office charge is disallowed.

Exam tips

Write the article name, such as Article 5 PE, along with the reason. Examiners reward the link between fact and rule.
In dual residence questions, list every tie-breaker test in order, even if you stop early. Show why each earlier test was not decisive.
For royalty and FTS, state the PE and effective connection check before quoting any rate.
Quote the four conditions of section 59(1) in short form when a PE is involved.
End with a clear conclusion in one line, naming the country with the taxing right.

Key Treaty Articles and Tie-Breaker Rules: frequently asked questions

What are the tie-breaker rules for dual residents?

For an individual, apply in order: permanent home, centre of vital interests, habitual abode, nationality, then mutual agreement. Stop at the first test that gives one country. Companies often use place of effective management, but check the treaty.

When does a foreign enterprise have a PE in India?

Generally when it has a fixed place of business in India through which it carries on business, or in many treaties a dependent agent who habitually concludes contracts. Preparatory or auxiliary activities are usually excluded. Read the treaty's definition.

How are royalty and fees for technical services taxed under a DTAA?

Usually the source country may tax them at a limited treaty rate. If the recipient has an effectively connected PE or fixed place in the source country, the income is taxed as business profits. Section 59 of the Income-tax Act, 2025 covers this case.

Can I deduct head office payments from PE income?

Not under section 59(2)(b), except reimbursement of actual expenses. Expenses not wholly and exclusively for the PE business are also disallowed.
