5 Jun 2026Double taxation is one of the most frustrating aspects of being an NRI. You earn income in your country of residence, and India wants a share too. Or you sell property in India, pay tax here, and your home country also taxes the same gain. The Double Taxation Avoidance Agreement (DTAA) exists precisely to prevent this — but only if you know how to use it correctly.
What Is DTAA and Why It Matters for NRIs
India has signed DTAAs with over 90 countries under Section 90 of the Income Tax Act. These bilateral treaties allocate taxing rights between the two countries and, in most cases, either exempt certain income from double taxation or provide a credit mechanism for taxes paid in one country against liability in the other.
A critical and underused provision: Section 90(2) of the Income Tax Act explicitly states that the taxpayer can opt for whichever is more advantageous — the domestic tax law or the treaty. The DTAA overrides domestic law where it is more beneficial. This is a right that many NRIs simply don't exercise because they're unaware of it.
Key DTAA Provisions Relevant to NRIs
Salaries and employment income: Most DTAAs provide that employment income is taxable only in the country where the work is performed. If you work in the UAE, your salary is generally not taxable in India — regardless of whether you receive it in an Indian bank account.
Interest income: Many DTAAs cap the withholding tax rate on interest income from India at 10–15%, which is lower than the domestic TDS rate of 30% (plus surcharge) on NRO account interest.
Capital gains on immovable property: This is where NRIs are most frequently misled. Most DTAAs — including India-UAE and India-US — do not exempt capital gains on Indian immovable property from Indian tax. The situs rule applies: if the asset is in India, India retains the right to tax it. DTAA relief here typically takes the form of a credit in your country of residence, not an exemption in India. For a full breakdown of how NRI capital gains tax on property works in India, including TDS rates and Section 54 exemptions, read our detailed guide.
Business income: Taxable in India only if you have a Permanent Establishment (PE) in India. Providing occasional professional services remotely from abroad generally does not create a PE.
Country-by-Country DTAA Analysis
India-UAE DTAA: The UAE does not levy personal income tax. The DTAA's primary function is to confirm India's taxing rights on India-sourced income — it doesn't create additional benefit for NRIs in UAE since the UAE was never going to tax them anyway. NRIs in UAE still owe Indian tax on Indian rental income, capital gains on Indian property, and NRO interest. The DTAA does not provide an exemption from Indian tax.
India-US DTAA: More complex because the US taxes its citizens on worldwide income regardless of residence. The DTAA provides a Foreign Tax Credit (FTC) mechanism: report your Indian income to the IRS and claim credit for Indian taxes paid against your US tax liability. The DTAA has a saving clause that largely preserves US taxing rights over US citizens, so Indo-American NRIs often face both Indian and US tax with an FTC offset.
India-UK DTAA: The UK taxes residents on worldwide income. A similar FTC mechanism applies. For capital gains from Indian property, you pay Indian CGT first, then claim credit in the UK against your Capital Gains Tax liability. The two tax systems compute gains differently (indexation, base cost rules), so residual double taxation can still arise.
India-Singapore DTAA: Generally favourable for business income and dividends. Post-2017 amendments removed the capital gains exemption on shares of Indian companies that previously made Singapore a preferred holding structure. The Limitation of Benefits (LOB) clause now restricts treaty shopping.
India-Canada DTAA: Similar FTC structure. NRIs in Canada also need to navigate RRSP income, which has specific treaty treatment under the India-Canada DTAA's pension provisions.
The Documentation You Must Have — No Exceptions
DTAA relief in India is not automatic. The Finance Act 2012 and subsequent amendments made documentation mandatory. Missing paperwork is the single biggest reason NRIs lose their treaty benefits at source.
1. Tax Residency Certificate (TRC)
A certificate from the tax authority of your country of residence confirming that you are a tax resident there for the relevant year. Examples: UAE Federal Tax Authority TRC, US IRS Form 6166, UK HMRC residency confirmation letter. Mandatory under Section 90(4). Without this, the Indian tax authority or the payer (your bank, your tenant) will apply domestic rates regardless of the treaty.
2. Form 10F
In addition to the TRC, you must file Form 10F online on the Indian income tax portal. Made mandatory from July 2022. This self-declaration provides: your PAN, address, nationality, tax identification number in your country of residence, and the period of residency. Form 10F alone is not enough — you need both Form 10F and TRC together.
3. PAN Card
Required to file Form 10F and to claim DTAA benefits. Also required to avoid Section 206AA, which imposes a minimum 20% TDS on all payments to non-PAN holders — overriding any DTAA benefit entirely.
How to Claim DTAA Relief in Practice
For TDS on income paid to NRIs (rent, dividends, interest), the payer is required to deduct TDS at the domestic rate unless you furnish TRC + Form 10F and formally request DTAA rate application. Submit these documents to your payer — your bank, your tenant, your employer's Indian subsidiary — before the income is paid.
If TDS has already been deducted at the higher domestic rate, you file an ITR and claim the excess TDS as a refund. You can also apply to the Assessing Officer under Section 197 for a lower deduction certificate citing the DTAA rate — particularly useful for recurring income like rent or interest. For property sales, this intersects with the Section 195 TDS and Form 13 process covered in our NRI capital gains guide.
DTAA vs Domestic Exemptions: Always Compare Both
Sometimes domestic Indian law offers better relief than the DTAA. For example:
- NRE account interest is fully exempt under Section 10(4) of the Income Tax Act — the DTAA provisions on interest are entirely irrelevant here because the domestic exemption is complete.
- If LTCG from a property sale qualifies for full Section 54 reinvestment exemption, there is no taxable gain — making DTAA analysis unnecessary for that transaction.
- Where a DTAA provides a 10% withholding cap on dividends but the domestic rate is 10% anyway, there is no treaty benefit to claim.
Section 90(2) gives you the legal right to compute tax under both regimes and choose the lower liability. Always do both calculations before deciding.
When DTAA Claims Get Rejected — Common Reasons
- TRC not submitted to the payer before income was paid — payer applies domestic TDS rate and the excess TDS must be recovered via ITR refund
- Form 10F not filed online — the requirement went online in July 2022; paper submissions are no longer accepted
- TRC for wrong year — the TRC must cover the financial year in which the income is received; a prior year TRC is not valid
- Claiming DTAA on capital gains from Indian property as if it provides an exemption — most DTAAs only provide a credit in the residence country, not an exemption in India
- No PAN — Section 206AA overrides DTAA; always ensure your PAN is active and updated
Frequently Asked Questions — DTAA for NRIs
What is DTAA and how does it help NRIs?
DTAA (Double Taxation Avoidance Agreement) is a bilateral treaty between India and another country that prevents the same income from being taxed twice. For NRIs, it provides either an exemption from tax in one country or a credit mechanism where tax paid in one country offsets the liability in the other. India has DTAAs with over 90 countries under Section 90 of the Income Tax Act.
Do NRIs in UAE get any benefit from the India-UAE DTAA?
Limited practical benefit, because the UAE does not levy personal income tax. The India-UAE DTAA confirms India's right to tax India-sourced income — it does not exempt NRIs in UAE from paying Indian tax on rental income, capital gains on Indian property, or NRO account interest. The DTAA simply ensures the UAE does not also tax that income, which was never an issue anyway.
What documents are needed to claim DTAA benefit in India?
You need two documents: (1) a Tax Residency Certificate (TRC) from the tax authority of your country of residence covering the relevant year, and (2) Form 10F filed online on the Indian income tax portal. Both are mandatory under Section 90(4). You also need a valid PAN to avoid Section 206AA overriding your DTAA claim.
Does DTAA exempt NRIs from capital gains tax on Indian property?
No. Most DTAAs — including India-UAE and India-US — allow India to tax capital gains on Indian immovable property under the situs rule. DTAA relief on property capital gains typically comes in the form of a foreign tax credit in your country of residence, not an exemption from Indian tax. The Indian capital gains tax remains payable.
Can DTAA override the domestic TDS rate on NRO interest?
Yes. Many DTAAs cap withholding tax on interest at 10–15%, compared to the domestic TDS rate of 30% plus surcharge on NRO account interest. To apply the DTAA rate, you must submit your TRC and Form 10F to your bank before the interest is credited. If TDS has already been deducted at 30%, claim the excess as a refund in your ITR.
What is Section 90(2) and why is it important for NRIs?
Section 90(2) of the Income Tax Act provides that a taxpayer can choose whichever is more beneficial — the domestic tax law or the applicable DTAA. This means NRIs are not forced to follow the DTAA if domestic law gives a better outcome. Always compute your tax liability under both regimes before deciding which to apply.
