DTAA Explained: How NRIs Avoid Being Taxed Twice

When you earn dividend or interest income from India while living abroad, that income can, in principle, be taxed twice: once by India via TDS at the point the income is paid, and again by your country of residence, which usually taxes its residents on their worldwide income. A Double Taxation Avoidance Agreement (DTAA) is a bilateral treaty between India and another country that fixes this by capping how much India can withhold at source, and/or letting you claim a credit in your resident country for tax already paid in India.

India has signed DTAAs with dozens of countries, but the mechanics that matter for a retail NRI investor -- exactly which rate applies to plain dividend and interest income, and what an individual actually needs to file to claim it -- differ treaty by treaty. This guide covers the mechanics using the six countries independently verified on this site: USA, UK, Canada, Australia, Singapore, and UAE.

DTAA relief is not automatic -- the payer (bank, registrar/RTA, or broker) will deduct TDS at India's full domestic rate by default unless you proactively file two things before the income is paid: a Tax Residency Certificate (TRC) from your country of residence's tax authority for the relevant year, and a self-declaration in Form 10F. Without both on file with the payer in advance, you get the standard domestic TDS rate regardless of what the treaty allows.

A TRC is only valid for the financial year it was issued for, so this is not a one-time filing -- it needs renewing annually if you want continued treaty relief. If you miss filing it before income is paid, you generally cannot get the excess TDS back from the payer retroactively; your recourse is to claim the difference (or a foreign tax credit) when you file your Indian income tax return.

A fact that is easy to miss: the DTAA rate is not automatically the lower one. India's own domestic dividend TDS rate for NRIs is 20.8% (20% plus 4% cess). For the USA and Canada treaties, the individual-investor dividend rate under the treaty is 25% -- HIGHER than India's domestic rate -- because the lower 15% treaty rate in both those treaties is reserved for a company holding a large (10%+) shareholding, not an ordinary retail investor.

For a US- or Canada-resident NRI holding Indian shares directly (not through a large corporate structure), filing a TRC and Form 10F to claim the "DTAA rate" on dividends would do nothing useful, and if a payer mistakenly applied the treaty cap literally without checking the shareholding condition, it could even work out worse. Interest income is a cleaner story across all six countries checked here -- every treaty interest rate is comfortably below India's flat 31.2% domestic NRO interest TDS rate, so DTAA relief is worth claiming for interest regardless of which of these six countries you are in.

India's domestic TDS baseline (no treaty claimed) is 20.8% on dividends and 31.2% on NRO interest. Compare that against each treaty's individual-investor rate below -- 'beneficial' means claiming DTAA is worth it for that income type in that country; where it isn't, India's own domestic rate is already as good or better.

This guide (and the DTAA Calculator tool on this site) covers only dividend and interest income from shares, mutual funds, and NRO deposits, for individual retail investors in these six countries. It does not model surcharge, royalties or fees for technical services, or capital gains -- those are governed by different treaty articles entirely. It also does not cover countries beyond these six; if your country of residence is not listed, the same TRC + Form 10F mechanism generally applies, but you would need to look up your specific treaty's rate independently or with a CA.
