India's DTAA network

India's agreements are called DTAAs — double taxation avoidance agreements — and the Income Tax Department publishes both the texts and the list of countries they cover. The network is broad and, for anyone with money moving between India and the West, unavoidable: the same salary, rent, dividend or capital gain is frequently within the charge of two countries at once.

Indian domestic law gives a treaty priority where the treaty produces a better result for the taxpayer, and that single rule is what makes the network usable rather than decorative. It is also why an Indian tax position is usually argued twice: once under the Act and once under the agreement, taking whichever is more favourable.

The Department's published list runs to 96 countries. It is a list of countries, not a status table — several entries appear under formal or historical names, which is a good sign that you are reading a transcript of the official document rather than someone's tidied-up version of it.

India also has agreements of a narrower kind alongside the comprehensive ones — limited agreements confined to particular income such as air or shipping traffic, and information-exchange agreements that carry no relief at all. If a country appears in a search result but not on a relief list, that is usually why.

For the corridors this practice handles most, the mechanics are set out for the Canada–India DTAA and the US–India treaty.

India decides residence under its own law first, on a test built around days of presence in the tax year and, for some people, in the preceding years. India's tax year runs April to March, so someone who moves mid-year is very often resident in both countries for overlapping periods — again, that is the normal case rather than a mistake.

Only when both countries treat the person as resident does the DTAA tie-breaker engage, and it runs in order: permanent home, centre of vital interests, habitual abode, nationality, and then agreement between the two authorities. Each rung is decided on evidence — where the family lives, where the home is kept available, where the bank and the doctor and the school are.

India also has a category for a person who is resident but not ordinarily resident, which narrows what India taxes without changing residence itself. It is easy to conflate that with treaty relief; they are separate mechanisms and both may be in play.

For companies, the place of effective management matters, and a board that meets abroad while the real decisions are taken in India is the classic exposure. The tie-breaker order and the evidence each rung needs are on the tie-breaker page; dual residency covers the overlap year.

Business profits. A foreign enterprise is generally taxable in India on business profits only through a permanent establishment, and India reads permanent establishment robustly — a dependent agent, a service presence, or a project past a stated duration can all create one. See business profits and PE.

Dividends, interest, royalties and fees for technical services. India withholds tax on payments to non-residents at a domestic rate, and the DTAA caps that rate. The cap varies by treaty and often by the recipient's shareholding, and India's agreements frequently carry a separate article for fees for technical services that has no equivalent in some other networks. The reduced rate applies only where the payer has the documentation in hand. See the dividends, interest and royalties articles and withholding on payments abroad.

Employment income. Short-stay relief exists in most Indian treaties on the usual conditions — a stay under a stated limit, a non-resident employer, and no charge of the cost to an Indian permanent establishment. See the employment income article.

Pensions, annuities and retirement accounts. Treatment turns on the type of plan and the treaty's own wording, and cross-border retirement savings are one of the areas where two countries most often disagree about timing. See pensions and annuities.

Capital gains. This is the article to read first in any Indian file. Allocation of gains differs sharply from treaty to treaty, including for shares, and protocols have changed the position for particular partners. Do not carry an answer across from another country's treaty.

Once the allocating articles are done, the relief article decides who credits whose tax — see how relief is given. Students and trainees have their own article — see students and trainees.

India is documentation-first, and the burden sits on the person claiming the benefit. A payer who cannot see the paperwork withholds at the domestic rate, and the recipient then has to reclaim through a return — a slower and more expensive path than getting the file right before payment.

Two documents do most of the work. A tax residency certificate from the other country's tax authority establishes that the recipient is resident there for treaty purposes. Alongside it, India requires prescribed information about the recipient — filed on Form 10F where the certificate does not already contain it — which the payer keeps as its authority for applying a treaty rate.

Where the statutory withholding rate is higher than the amount that will actually be due, the payer or the recipient can apply for a lower or nil deduction certificate rather than over-withholding and reclaiming. See lower and nil TDS certificates, and withholding on payments abroad for the payer's own obligations.

Indian residents claiming credit abroad, or foreign credit for Indian tax paid, need proof of the tax actually paid and of the year it belongs to. Mismatched tax years — April-to-March against a calendar year — are the routine cause of a credit being disallowed as unsupported.

Keep every document that was current when the payment was made, including the certificate's own validity period. See certificates of residency.

India was an early and enthusiastic party to the multilateral instrument, and a great many of its agreements are modified by it. The practical consequence is the same as elsewhere: the operative text is the agreement plus its protocols plus the multilateral overlay, and a PDF of the original convention is not the current law.

The principal purpose test applies to arrangements whose main point was to obtain the benefit, and Indian practice around beneficial ownership and substance is well developed — a holding company with no people, no decisions and no purpose beyond the treaty rate is the case the test was written for. See the principal purpose test and beneficial ownership.

India also has domestic anti-avoidance machinery that sits outside the treaty and can apply alongside it, so clearing the treaty test is not the end of the analysis. Advance rulings are available where a position needs certainty before the transaction rather than after it.

Where India and the other country reach incompatible conclusions, the mutual agreement procedure is the route, and India publishes its own guidance on how it runs one. See the competent authority route and limitation on benefits.

Assuming the capital gains article matches the one you already know. It very often does not. Gains are the article where Indian treaties diverge most, and protocols have moved the position for specific partners.

Letting the residency certificate lapse. A certificate covers a period. A payment made outside that period is unsupported even where the person's residence never changed.

Ignoring the tax-year mismatch. April-to-March against January-to-December means a credit claim has to be mapped between years and evidenced. Unmapped claims get disallowed for want of proof rather than for want of entitlement.

Treating a limited agreement as a comprehensive one. Some of India's agreements cover only shipping or air transport, and information-exchange agreements grant no relief at all. Check what the agreement actually covers before relying on it.

Forgetting the fees-for-technical-services article. Payments for consultancy and technical work are a distinct category in many Indian treaties, and applying the royalties article by analogy produces the wrong rate and the wrong documentation.

The India desk's treaty work is described here, with the fee agreed before anything starts.
