If you are an NRI, the same income can be taxed both in India and in your country of residence. The Double Taxation Avoidance Agreement (DTAA) stops that — either by exempting the income in one country or by giving you a credit for the tax paid in the other. In India, relief runs through Section 159 (old Sections 90/90A) for treaty countries and Section 160 (old Section 91) where there is no treaty. To claim it you need a Tax Residency Certificate, Form 10F, and (for a credit) Form 44 (the old Form 67). Used correctly, the DTAA can cut your Indian TDS to as little as 10–15% and ensure you never pay full tax twice.
Double taxation is the single biggest source of anxiety — and of overpaid tax — for NRIs. When you live in one country and earn from another, both countries have a claim on that income: India taxes it because it arises in India, and your country of residence taxes it because you are resident there and it taxes worldwide income. Left unmanaged, you could genuinely pay tax on the same rupee twice. The Double Taxation Avoidance Agreement (DTAA) — a treaty India has signed with more than 90 countries — exists precisely to prevent this. It does so in one of two ways: it either lets only one country tax a particular income (and exempts the other), or it lets both tax it but requires your home country to give you credit for the tax you already paid in India. The practical upshot is that, done properly, you pay tax once, usually at the lower of the two rates, and often at a concessional treaty rate far below India's domestic withholding rate. The catch is that the relief is not automatic — you must claim it with the right documents, and NRIs who don't lose real money. This guide walks through exactly how it works, what you need, and how it plays out for the biggest NRI corridors.
To understand the fix, you have to understand the problem. Every country taxes income on some combination of two principles: the source principle (income arising within its borders is taxable there, whoever earns it) and the residence principle (its residents are taxed on their worldwide income, wherever it arises). India applies both. For an NRI, India taxes only your Indian-sourced income — rent from an Indian flat, interest from an NRO deposit, capital gains on Indian shares or property, and so on. But the country where you now live — the USA, the UK, Canada, Australia and many others — taxes its residents on their global income, which includes that same Indian income. Two countries, two valid claims, one income: that is juridical double taxation. The DTAA is the agreed rulebook that decides which country gets to tax what, and how the other country must step back or give credit, so the overall burden is not doubled.
Every DTAA delivers relief through one of two mechanisms, and knowing which applies to your income is the heart of the matter.
The exemption method means a particular type of income is taxable in only one of the two countries; the other simply exempts it. For example, under many treaties, a salary earned and taxed abroad may be exempt in India, or business profits without a permanent establishment in India are taxable only in the residence country. Where the exemption method applies, you don't pay Indian tax at all on that income (though you may still have to report it).
The credit method (also called the tax-credit or relief method) means both countries can tax the income, but the country of residence gives you a credit for the tax you paid in the source country. So if India deducts tax on your Indian rental income, your home country taxes the same rental income but then reduces its tax by the amount of Indian tax you already paid. You are never worse off than the higher of the two rates, and you never pay the full tax twice. Most NRI situations — rent, interest, dividends, capital gains — run on the credit method, which is why understanding the foreign-tax-credit paperwork matters so much.
Under the Income-tax Act, 2025, DTAA relief is delivered through two sections that replaced the familiar old provisions:
The practical significance of Section 159 is that you are never forced to accept the higher domestic rate when a treaty offers a lower one. If India's domestic withholding on a certain income is, say, 20% but the treaty caps it at 10%, you apply the 10% — provided you have the documents to claim the treaty.
Treaty benefits are a claim you make, not a discount you're handed. To access them, an NRI needs three things, and missing any one of them can cost you the concessional rate:
With TRC + Form 10F + PAN in place, you can present the treaty rate to Indian payers (banks, tenants, companies) so they withhold at the lower treaty rate, and you can substantiate the treaty position in your Indian return.
The reason the DTAA is worth the paperwork is that treaty withholding rates are frequently much lower than India's domestic rates for NRIs. Domestic TDS on many NRI incomes is deducted under the withholding provisions of Section 393 (the old Section 195), often at high headline rates. The treaty then caps the rate. A few common patterns illustrate the point (exact figures depend on the specific treaty and must be checked for your country):
Because Section 159 lets you pick the more beneficial of treaty and Act, you always apply whichever is lower — but only if you have claimed the treaty with a valid TRC and Form 10F. An NRI who lets a bank deduct the full domestic rate for want of a TRC is simply overpaying and then chasing a refund.
When the credit method applies — which is most of the time — the mechanics matter. Suppose India has taxed your Indian rental income at, say, 30%, and your home country also taxes that rental income as part of your worldwide income. Your home country will give you a credit for the Indian tax paid, so you don't pay twice; the exact process is governed by your home country's rules. In the reverse direction — where you are a resident of India claiming credit in India for tax paid abroad (relevant for returning NRIs and RNORs with foreign income) — India requires you to file Form 44 (the old Form 67) to claim the foreign tax credit, giving details of the foreign income and the tax paid on it. Crucially, Form 44 must be filed on or before the return for the credit to be allowed, and it must be supported by proof of the foreign tax paid. Missing the form or filing it late is a common reason a genuine foreign-tax-credit claim gets denied. Keep your foreign tax payment challans, withholding certificates and payslips to substantiate the claim.
Sometimes both India and another country consider you a tax resident in the same year — for instance, in the year you move, or if you split your time. The treaty contains tie-breaker rules that decide which country you are treated as resident of for treaty purposes, applied in order: first the country where you have a permanent home; if in both, the country of your centre of vital interests (closer personal and economic ties); then your habitual abode; then your nationality; and finally by mutual agreement between the two tax authorities. These rules matter because your residence status determines which country gets primary taxing rights and how relief flows. For anyone in a transition year — moving abroad, returning to India, or on a long overseas assignment — getting the residence and tie-breaker analysis right is essential, and often decides thousands of rupees of tax. This interacts with your Indian residential status and the RNOR transitional status, which shelters foreign income for a couple of years after you return.
For the very large NRI community in the United States, the India–USA DTAA is the reference point. As a US tax resident, you are taxed by the IRS on your worldwide income, including your Indian income, and you can claim a US foreign tax credit for the Indian tax you pay — so the Indian tax is not lost, it offsets your US liability. On the Indian side, you present your US TRC (IRS Form 6166) and Form 10F to claim treaty rates on Indian interest, dividends and other income. Two extra US-specific wrinkles matter: the US taxes its citizens and green-card holders regardless of where they live, and it has extensive FATCA reporting, so your Indian bank accounts and assets may need to be reported to the IRS on FBAR/Form 8938 — a compliance obligation separate from, but connected to, your Indian tax. The India–USA treaty also has specific articles for pensions, social security, students and independent personal services that can change the outcome for particular incomes, so US-based NRIs benefit most from a coordinated India–US review.
NRIs in the UAE, Saudi Arabia, Qatar and similar Gulf jurisdictions face a very different situation, because these countries historically levy little or no personal income tax. That has two consequences. First, on your UAE-sourced salary and income, there is generally no Indian tax at all if you qualify as an NRI, because that income neither arises in India nor is taxable to a non-resident here — this is exactly why Gulf employment is so tax-efficient for NRIs, provided you genuinely meet the non-resident day-count tests. Second, on your Indian income (rent, NRO interest, capital gains), India will still tax it, and because the UAE imposes no personal income tax on individuals, there is usually no second tax to credit against — so the DTAA mainly helps by capping Indian withholding at treaty rates. The India–UAE treaty does provide concessional rates and its own residency rules, and a UAE TRC plus Form 10F still let you access lower Indian TDS on interest and dividends. The critical risk for Gulf NRIs is not double taxation but residential status: spending too many days in India, or falling under the deemed-resident rule for high Indian income with no tax paid anywhere, can pull your global income into the Indian net. Careful day-counting is the real planning lever here.
For NRIs in the United Kingdom, the India–UK DTAA again generally operates on the credit method for Indian-sourced income. As a UK resident you are taxed on your worldwide income (subject to the UK's own rules, including the remittance basis for some individuals), and you claim UK relief for Indian tax paid. On the Indian side, your UK TRC and Form 10F unlock treaty rates on interest, dividends and royalties. The UK treaty contains detailed articles on pensions, government service, dividends and capital gains, and the interaction with the UK's remittance-basis rules can be complex for those who keep Indian income offshore. As with the US, the value of a coordinated review is that it aligns the Indian claim (treaty rate + correct reporting) with the UK claim (foreign tax credit), so neither side over-taxes.
Consider an NRI resident in the USA who earns ₹6 lakh of rent from a Delhi flat and ₹2 lakh of interest on an NRO fixed deposit in a year. Without any treaty planning, the bank may deduct TDS on the interest at around 30% plus surcharge and cess — roughly ₹62,000 — and tax is due on the rent as well. By obtaining a PAN, a US TRC (Form 6166) and filing Form 10F, the NRI presents the India–USA treaty rate on the interest (commonly 15%), reducing the interest TDS to about ₹30,000. The rental income is taxed in India after the 30% standard house-property deduction and, if applicable, the treaty rate. The NRI then files an Indian return (ITR-2), pays the correct Indian tax, and reports the same income on the US return — where the IRS gives a foreign tax credit for the Indian tax paid, so the income is not taxed twice. The net effect: Indian tax capped at the treaty rate, US tax reduced by the Indian credit, and the total burden equal to roughly the higher of the two rates rather than the sum of both. The saving versus doing nothing is substantial, and it comes almost entirely from the documents.
Now take an NRI resident in the UAE who sells Indian listed shares and books a long-term capital gain of ₹4 lakh in the year. India taxes long-term equity gains above the ₹1.25 lakh annual exemption at 12.5% under the special-rate provisions, so roughly ₹34,000 of Indian tax arises. Because the UAE imposes no personal income tax on the individual, there is no second tax in the UAE to worry about, and no double taxation to relieve — the DTAA's role here is simply to ensure India's rate is applied correctly and, where relevant, at treaty rates for other income like interest. The key point for this NRI is not credit mechanics but staying genuinely non-resident: if they spend too long in India and become a resident, their worldwide gains and income could be dragged into the Indian net, which is a far bigger cost than the ₹34,000. So for Gulf NRIs, the DTAA is one tool, but residential-status discipline is the main event.
A DTAA is organised into "articles", each dealing with a category of income and allocating the taxing right between the two countries. Knowing which article governs your income tells you whether to expect exemption or credit. In broad terms, and always subject to the specific treaty:
Because the article that applies changes the answer completely — exemption in one country versus credit across both — identifying the correct article for each stream of your income is the first analytical step in any DTAA claim.
The DTAA is not only for those living abroad — it matters just as much in the years around coming back to India. When you return, you don't become an ordinary resident overnight: you usually pass through a transitional status called Resident but Not Ordinarily Resident (RNOR), which can last for two or three years depending on your history. During RNOR, your foreign income generally stays outside the Indian tax net unless it is derived from a business controlled in or a profession set up in India — so foreign salary earned before return, overseas interest and foreign investment income are typically not taxed in India while you are RNOR. This is a valuable window: pension arrears, foreign bank interest, and gains realised abroad during this period can often be brought to India with little or no Indian tax. Once you become an ordinary resident, however, India taxes your worldwide income, and that is when the DTAA's credit mechanism (and Form 44) becomes central — you report your foreign income in India but claim credit for the tax already paid abroad, so you are not taxed twice. Planning the timing of large foreign receipts around the RNOR window, and lining up the treaty and foreign-tax-credit paperwork before you cross into ordinary residence, can save a returning NRI a very large amount of tax.
Putting it together, the typical NRI compliance flow is: obtain and keep a PAN; get a TRC from your country of residence each year; file Form 10F on the Indian portal; give these to Indian payers so they withhold at treaty rates; file your Indian return (usually ITR-2) reporting all Indian income and claiming the treaty position under Section 159; and, where you are claiming credit in India for foreign tax (as a resident/RNOR), file Form 44 before the return. Reconcile the Indian income and TDS with your Form 26AS and AIS, which now capture interest, dividends and high-value transactions, so your return matches the department's data and you avoid a mismatch notice. If tax was over-deducted because a payer ignored the treaty, you claim the excess back as a refund when you file. Each of these steps is routine once set up, but each is also a point where an unadvised NRI loses money.
The recurring, expensive errors are worth spelling out. First, not obtaining a TRC and Form 10F, so payers apply the full domestic rate and the NRI overpays and then has to chase a refund. Second, not having a PAN, which triggers higher withholding and blocks electronic Form 10F filing. Third, assuming the treaty applies automatically — it never does; it must be claimed with documents. Fourth, missing Form 44 (old Form 67) or filing it after the return, which forfeits a genuine foreign-tax-credit claim. Fifth, ignoring residential status, especially for Gulf NRIs, where too many days in India or the deemed-resident rule can pull worldwide income into the Indian net — a far bigger risk than any withholding rate. Sixth, failing to reconcile with AIS/26AS, which invites scrutiny. And seventh, overlooking home-country reporting such as FATCA/FBAR in the US, which is a separate obligation that can carry heavy penalties of its own. Avoiding these is mostly about setting up the documents once and filing on time — which is exactly the kind of thing a coordinated cross-border review handles.
Some NRI situations are simple enough to self-manage — a single NRO deposit, modest interest, a clean day-count. But the moment you have multiple income types across two countries, a transition year (moving abroad or returning), capital gains or property, a US or UK residence with its own credit and reporting rules, or a residential-status question, the interaction between the Indian treaty claim and your home-country return becomes the place where real money is won or lost. A coordinated review makes sure the Indian side (treaty rate, correct TDS, right ITR, Form 10F, Form 44 where needed) lines up with the home-country side (foreign tax credit, worldwide reporting), so you pay the legal minimum once and never twice. Given that the tax at stake usually dwarfs the cost of getting it right, this is one area where advice pays for itself.
The Double Taxation Avoidance Agreement is a treaty between India and another country that stops the same income being fully taxed in both. It either exempts the income in one country or gives a credit for the tax paid in the other, so an NRI pays tax once, usually at the lower of the two rates. In India, relief is given under Section 159 (old 90/90A) for treaty countries and Section 160 (old 91) where there is no treaty.
A Tax Residency Certificate (TRC) from your country of residence, Form 10F filed electronically on the Indian e-filing portal, and an Indian PAN. With these, Indian payers can withhold at the lower treaty rate and you can substantiate the treaty position in your return.
Yes. Domestic TDS on NRI interest, dividends and other income under Section 393 (old 195) is often much higher than the treaty rate. Under Section 159 you apply the more beneficial of the treaty and the Act — so with a valid TRC and Form 10F you can have TDS deducted at the concessional treaty rate (commonly 10–15% on interest and dividends).
Form 44 is the form used in India to claim a foreign tax credit for tax paid abroad on doubly-taxed income (relevant when you are an Indian resident/RNOR with foreign income). It must be filed on or before your Indian return, supported by proof of the foreign tax paid, or the credit can be denied.
Your UAE income is generally not taxable in India if you are genuinely an NRI, and since the UAE has no personal income tax there is usually no double tax to relieve on it. The DTAA still helps cap Indian withholding on your Indian income (rent, interest, capital gains) at treaty rates. The bigger issue for Gulf NRIs is maintaining non-resident status through careful day-counting.
Yes. Section 160 (old Section 91) gives unilateral relief even without a treaty — India grants a credit for the foreign tax paid on doubly-taxed income at the lower of the Indian and foreign rate, so you are not left fully double-taxed.
The Indian payer or the department can refuse the treaty rate and apply the higher domestic rate. You would then have to claim the excess back as a refund when you file your Indian return — extra tax locked up and paperwork you could have avoided by getting the documents in place first.
We set up your TRC, Form 10F and PAN, apply the right treaty rate, file Form 44 and coordinate both sides so you never pay tax twice.
