Cross-border individuals routinely become tax-residents of two countries under each country’s domestic law — an Indian on overseas deputation who meets both India’s 182-day test and the host country’s residency rule; a US-passport holder working in India long enough to be a tax-resident here. When that happens, the Double Taxation Avoidance Agreement (DTAA) provides a tie-breaker to assign residency to one country for treaty purposes. The cascade is in Article 4 of every DTAA modelled on the OECD or UN model conventions, and India has signed treaties with most of these models.
Why the tie-breaker matters
Without the tie-breaker, both countries would tax the individual’s worldwide income, with credit relief in one or both as a fallback. The credit mechanism works but is administratively painful and can leave the taxpayer with double-tax exposure on items not fully captured by foreign-tax-credit rules. The tie-breaker simplifies the position: one country becomes the residence country under the treaty, the other becomes the source country. The residence country gets worldwide taxing rights; the source country can tax only items sourced within it, with limited rates per the treaty.
The cascade in Article 4(2) — for individuals
Where an individual is a tax-resident of both contracting states under each state’s domestic law, residency is determined as follows, in order:
(a) Permanent home test
An individual is deemed to be a resident only of the state in which they have a permanent home available to them. “Permanent home” means a dwelling that is continuously available, not necessarily owned — a rented apartment maintained at the individual’s disposal qualifies, a hotel does not. If the home is in only one of the two countries, the test ends here.
(b) Centre of vital interests
If the individual has a permanent home in both countries, residency is determined by the centre of vital interests — the country with which the personal and economic relations are closer. The factors looked at include: family residence, social ties, political affiliations, business activities, source of income, location of bank accounts, place from which property is administered. This is the most fact-intensive of the four tests; it is the test that produces the most disputes.
(c) Habitual abode
If the centre of vital interests cannot be determined or the individual has none in either country, residency is in the country where they have a habitual abode — where they ordinarily live. The OECD Commentary suggests looking at how frequently and regularly the individual is present in each country, over a reasonable period.
(d) Nationality
If the individual has a habitual abode in both countries or in neither, residency follows nationality / citizenship. If the individual is a citizen of both states or of neither, the final fallback is for the competent authorities of the two states to settle the matter by mutual agreement.
How the test plays out — three worked examples
Example 1: Indian senior executive on US deputation
An Indian citizen, deputed to the US by the Indian parent for 24 months. Family remains in India in the family-owned home. The executive rents an apartment in San Francisco for the deputation period. Bank accounts, fixed deposits, investments are predominantly in India. Indian parent continues to pay a portion of salary in India.
- Permanent home test: Both. Owned home in Bangalore, rented apartment in San Francisco — both continuously available.
- Centre of vital interests: India. Family, social ties, principal investments, and significant income source are in India.
- Tie-breaker assigns residency to India. The US treats the executive as a non-resident alien for treaty purposes. The US still taxes US-source salary as a non-resident; India taxes the worldwide income (with US-tax credit under Article 23).
Example 2: Returning NRI senior executive
An NRI working in Dubai for 15 years returns to India in October. Maintains Dubai apartment for an expected 6-month transition, but has moved family and household effects to India. New employment with an Indian employer from October.
- Permanent home test: Both for the transition period (Dubai apartment continuously available; new family home in Bangalore).
- Centre of vital interests: India from October. Family relocated, new principal employment in India, principal social ties shifting.
- Tie-breaker assigns residency to India from the date of relocation. UAE has no income tax so the result has no double-tax consequence, but the treaty position is established for any future audit.
Example 3: Dual-citizen with property in both countries
An Indian-origin US citizen with permanent residence in the US, family in the US, business income from a US LLC, but also owns a Bangalore apartment used personally for 4 months a year and let out for the rest. Annual visits to India total 130 days.
- Indian domestic residency: Generally non-resident under the standard 182-day test, though the deemed-resident rule for high-income NRIs may apply if other conditions are met.
- If treated as Indian-resident on a particular year: Permanent home — both countries.
- Centre of vital interests: US. Family, business, social ties all in the US. India is a holiday / investment location.
- Tie-breaker assigns residency to the US. India treats the individual as non-resident for treaty purposes, can tax India-source rental income at the treaty rate (typically 15% on gross rent or net under the article).
Article 4 for companies
For non-individuals (companies, partnerships), the tie-breaker is different. Until the 2017 OECD model update, the test was place of effective management (POEM) — where the key management and commercial decisions are taken. India aligned with this in domestic law from FY 2016-17.
Post the 2017 update, the OECD model shifted to the Mutual Agreement Procedure (MAP) approach — the two competent authorities decide residency, taking into account POEM, place of incorporation, and where the company is managed. Newer Indian treaties (and the post-MLI revisions to older treaties) reflect this shift. For most existing Indian treaties, the POEM test is still the operative one.
The TRC and Form 10F requirements
To claim treaty benefit, the non-resident must provide a Tax Residency Certificate (TRC) from the home country and file Form 10F on the Indian e-filing portal. Section 90(4) of the Income-tax Act makes the TRC mandatory; the CBDT clarification of August 2022 requires Form 10F to be filed electronically by the non-resident. Both documents need to be in hand before the Indian tax position is taken — the deductor (employer / payer) is required to verify them before applying treaty rates.
Form 10F captures: status (individual / company), nationality, country of residence for tax purposes, period for which TRC is valid, tax identification number in the home country, the relevant period for which residency is being claimed, and the assessee’s address.
The Limitation of Benefit (LOB) clause
Most modern Indian treaties (after 2016) include a Limitation of Benefit (LOB) clause — treaty benefits are denied where the principal purpose of an arrangement was to obtain the treaty benefit. The LOB tests look at substance: real activity in the residence country, real economic substance of the entity claiming benefit, not just paper presence in a low-tax jurisdiction.
The General Anti-Avoidance Rule (GAAR) in Indian domestic law, in force from FY 2017-18, complements the LOB clauses. Both can be invoked to deny treaty benefits where the arrangement lacks substance.
The interaction with the deemed-resident rule
The Indian deemed-resident rule (Section 6(1A) introduced by the Finance Act 2020) deems an Indian citizen with India-source income above Rs 15 lakh and not liable to tax in any other country to be a resident in India. This deemed-resident rule plays cleanly with the DTAA tie-breaker: if the citizen is treated as resident in India by deeming but as resident in another country under that country’s law, the Article 4 cascade still resolves the conflict. In practice the deemed-resident rule mostly applies to individuals with no substantive residence anywhere — the tie-breaker rarely fires.
