A treaty does not apply itself
If you live outside India and still receive income from it, two tax systems can reach the same rupee. The double taxation avoidance agreement between India and your country of residence exists to stop that, but it works nothing like people expect.
The single most important point is that treaty relief is claimed, not conferred. A bank paying interest on an NRO account, a company paying a dividend, a tenant paying rent — each deducts tax at the rate the Income-tax Act specifies unless you have established, before payment, that a lower treaty rate applies. The default position is domestic law; the treaty is an exception you invoke.
Invoking it is a documentary exercise. The central document is a Tax Residency Certificate issued by the country where you live, and section 90 of the Income-tax Act makes it a precondition rather than a nicety.
The two methods of relief, and why they give different answers
Treaties relieve double taxation in one of two ways, and which one applies depends on the treaty and often on the income type.
| Method | How it works | Typical outcome |
|---|---|---|
| Exemption | One country does not tax the income at all | You pay only the taxing country's rate |
| Credit | Both tax it; your residence country credits the source-country tax | You pay roughly the higher of the two rates |
The distinction is not academic. Under the credit method, a low rate of tax deducted in India gives you a smaller credit against a larger liability at home, so the saving passes to the residence country's treasury rather than to you. Under the exemption method, the low Indian rate is the whole story.
Two refinements matter. Exemption is often exemption with progression, where the exempting country leaves the income untaxed but still counts it when setting the rate on your other income. And credit is usually capped at the residence country's own tax on that income, so a larger source-country deduction produces excess credit rather than a refund.
When both countries claim you as resident
Relief presupposes that one country is the residence country and the other the source country. Where both treat you as resident under domestic rules — entirely possible in a year of arrival or departure — the treaty's residence article resolves the conflict through tie-breaker tests applied strictly in order.
| Order | Test | What it asks |
|---|---|---|
| 1 | Permanent home | Where is a home permanently available to you? |
| 2 | Centre of vital interests | Where are your personal and economic ties closer? |
| 3 | Habitual abode | Where do you actually spend your time? |
| 4 | Nationality | Of which state are you a national? |
If a test resolves the position, the sequence stops there; only if all four fail is the matter referred to the competent authorities of both states. Note that a permanent home means one available to you, not one you own — a rented flat kept year-round counts, and a property let out commercially generally does not.
Because Indian residence itself is decided by day counts and look-back periods, working the domestic test first is a prerequisite. Our India residential status test sets out the section 6 conditions, and the RNOR planning guide covers the transitional status between resident and non-resident.
Withholding at source: where the treaty earns its keep
For most non-residents the practical benefit of a treaty is a reduced rate of tax deducted at source on Indian interest, dividends and royalties. Domestic rates under the Income-tax Act apply by default; treaty rates, where lower, apply only on production of the required documents to the payer before payment.
That timing point deserves emphasis. Once a deduction has been made, the money has gone to the exchequer and the payer cannot reverse it. Recovering the difference means filing an Indian return and claiming a refund.
TRC, Form 10F and the permanent establishment declaration
Three documents typically make up a treaty claim.
The Tax Residency Certificate comes from the tax authority of your country of residence and confirms your residence there for a stated period. India cannot issue it for this purpose, and lead times vary between authorities.
Form 10F is an Indian self-declaration supplying particulars the foreign certificate may omit — status, nationality, tax identification number, address and the period claimed. It is now filed electronically on the income tax portal in most cases, which practically requires a PAN.
A no permanent establishment declaration confirms you have no fixed place of business in India through which the income arises. Where one exists, reduced treaty rates on business profits generally fall away and the income is taxed as attributable to that establishment.
If you cannot produce a TRC
The consequence is simple and unwelcome: domestic withholding rates apply. Payers rarely accept an assurance in place of the certificate, because liability for under-deduction rests with them.
Higher rates can also apply where a PAN has not been furnished, a point that catches non-residents who assumed no Indian tax number was needed. If your income from India is regular — rent, deposit interest, dividends — treat the TRC as an annual renewal exercise. Our guides to NRE, NRO and FCNR accounts and rental income and TDS cover where these deductions arise.
The zero-tax jurisdiction problem
For residents of the Gulf states and other jurisdictions without personal income tax, the ordinary logic of relief breaks down. There is no foreign tax to credit, so the benefit, if any, lies entirely in reduced Indian withholding.
The difficulty is qualifying at all. Many treaties define a resident of a contracting state by reference to liability to tax there, and where no such liability exists the Indian authorities have contested whether the person is a treaty resident. Some treaties and protocols address this explicitly; others do not, and the position has been litigated. This is where the identity of your treaty partner matters most, and where general reasoning is least reliable.
Anti-avoidance and limitation of benefits
Documentation establishes eligibility. It does not settle whether the arrangement behind the claim is respected.
The General Anti-Avoidance Rule in the Income-tax Act allows the authorities to disregard an impermissible avoidance arrangement — broadly, one whose main purpose is a tax benefit and which lacks commercial substance. Separately, many treaties now carry limitation-of-benefits articles or a principal purpose test, introduced across a large number of agreements through the OECD multilateral instrument, denying benefits where obtaining them was a principal purpose. Genuine residence supported by real ties is rarely troubled by either; structures assembled to route income through a favourable treaty are the intended target.
Treaty terms differ, and the differences are material
India's treaties are not variations on a single template. Withholding limits, the definition of royalties and fees for technical services, capital gains articles, and pension provisions all vary from one agreement to the next, and protocols and the multilateral instrument have widened those differences further.
Nothing here substitutes for reading the specific agreement between India and the country where you live. The country guides beneath this one set out how each treaty handles the main income categories.
Compliance caveat
This guide describes the general mechanism of treaty relief under section 90 of the Income-tax Act, the documentation requirements including the Tax Residency Certificate and Form 10F, and the structure of tie-breaker and anti-avoidance provisions found in Indian treaties. It does not state withholding rates under any particular treaty, address specific income types in detail, or cover FEMA residence, which is determined separately under RBI regulations and can differ from your income-tax position. Treaty texts, protocols and domestic rates change. This is a simplified guide, not tax advice.

How Global Investments can help
Treaty relief fails far more often on administration than on entitlement — a certificate requested too late, a Form 10F not filed, a payer who deducted at the domestic rate because nothing was in front of them. Our advisers work with clients holding Indian income from abroad to identify which treaty applies, establish which country has the residence claim where both assert one, and put documentation in place before payments are made rather than reclaiming afterwards. Where you are resident in a jurisdiction that levies no income tax, we look specifically at whether treaty residence can be established at all, and coordinate with Indian tax specialists on how the claim should be framed. Get in touch to discuss your position.
Frequently asked questions
What is a Tax Residency Certificate and who issues it?
A Tax Residency Certificate is a document issued by the tax authority of the country where you are resident, confirming that you were treated as tax resident there for a specified period. India does not issue it for foreign treaty claims and cannot substitute for it. Section 90 of the Income-tax Act makes it a precondition of claiming treaty benefit, so the certificate has to be obtained from the foreign authority in advance rather than assembled after an assessment has been raised.
Does a treaty automatically reduce the tax deducted on my Indian income?
No, and this is the most common and most costly misunderstanding. A payer in India deducts at the domestic rate specified in the Income-tax Act unless you have positively established your entitlement to the treaty rate before payment is made. That means providing the TRC, Form 10F and any declaration the payer requires ahead of time. If the paperwork arrives late, the deduction stands and your only remaining route is a refund claim through an Indian return.
What is the difference between the exemption method and the credit method?
Under the exemption method one country simply does not tax the income at all, leaving the other to tax it in full, though the exempting country may still count the income when setting the rate on your remaining income. Under the credit method both countries tax the income but your residence country allows a credit for tax paid in the source country. The credit method generally leaves you paying the higher of the two effective rates, whereas exemption can leave you paying only the lower.
What happens if both India and my country of residence treat me as resident?
The treaty tie-breaker in the residence article resolves it, applying a fixed sequence of tests until one produces an answer. It looks first at where you have a permanent home available, then at your centre of vital interests, then at your habitual abode, and finally at nationality, with unresolved cases referred to the two authorities. The outcome decides which country taxes you as a resident and which is limited to source taxation, so it is worth establishing rather than assuming.
I live in a country with no personal income tax. Does a treaty still help me?
It may, but the analysis is materially harder. Where there is no foreign tax there is nothing to credit, so the value of a treaty lies in reduced Indian withholding rather than in relief for tax paid elsewhere. The obstacle is that many treaties and their protocols require a person to be liable to tax in the other state to qualify as a resident of it, and Indian authorities have contested claims where no such liability exists. Position this carefully with local advice.
What is Form 10F and do I need it if I already have a TRC?
Form 10F is the Indian self-declaration supplying the particulars that a foreign TRC may not itself contain, such as nationality, tax identification number, address and the period of residence claimed. It supplements the TRC rather than replacing it. It is now filed electronically on the Indian income tax portal in most circumstances, which in practice means having a PAN, and payers routinely refuse to apply a treaty rate without both documents in hand.
Can Indian tax authorities refuse a treaty claim that is properly documented?
Yes, in defined circumstances. The General Anti-Avoidance Rule in the Income-tax Act permits the authorities to disregard arrangements whose main purpose is obtaining a tax benefit and which lack commercial substance, and many treaties now carry limitation-of-benefits provisions or a principal purpose test introduced through the multilateral instrument. Documentation establishes eligibility; it does not by itself answer a challenge to the substance of the arrangement behind the claim.
