Double Taxation Avoidance Agreements (DTAA)

Three ways a DTAA provides relief

• Exemption method, one country gets exclusive taxing rights. An NRI in Qatar selling Indian mutual funds, for instance, may find the entire capital gain taxable only in Qatar under the India-Qatar treaty, not in India at all
• Concessional rate, both countries can tax, but the treaty caps the rate. Dividend income that would normally attract 20% tax in India might be capped at 10% under a specific treaty
• Tax credit method, both countries tax the income, but your country of residence gives you credit for tax already paid in India, so you are not paying the full rate twice

A worked example, NRO interest earned by a UK resident

Interest income of 36,00,000 rupees gets TDS deducted at 31.2% (11,23,200 rupees), well above the DTAA concessional rate of 15% (5,40,000 rupees). Filing your Indian return and applying the DTAA rate gets you a refund of the 5,83,200 rupee difference, and you can separately claim foreign tax credit in the UK for the 5,40,000 rupees already paid in India.

A genuinely important caveat from the same example: if your income is small enough to already fall below India’s basic exemption limit, applying DTAA can actually increase your liability, since the treaty rate might exceed zero while the domestic provision would have given you nil tax. Always compare both before choosing.

How to actually claim it

1. Determine your residential status under the DTAA’s specific residence article, this decides your eligibility
2. Check which article of the treaty covers your specific income type, since capital gains, interest, dividends, and salary are often treated differently
3. Submit your documents to the payer: a Tax Residency Certificate (TRC), self-attested passport and visa copies, a declaration for banks, your OCI card if applicable, and your PAN copy if available

The Tax Residency Certificate is the linchpin document

It is issued by your country of residence’s tax authority, confirming your tax residency there for a specific period, and needs to include your name, status, nationality, tax ID, the period covered, and your address abroad, all verified by that country’s government. It is valid for one financial year only, so you need a fresh one annually.

Form 10F is mandatory alongside the TRC. Since a 2022 CBDT notification, anyone claiming DTAA relief must file this electronically on the income tax e-filing portal, the TRC alone is not sufficient anymore.

Submitting your TRC to the payer directly (a bank, for instance) lets them withhold tax at the concessional rate from the start. Skipping this and only claiming DTAA benefit while filing your return still works, but means waiting for a refund on the excess withheld, at the department’s discretion and timeline.

One structural point worth knowing: India has signed the Multilateral Instrument (MLI), which has applied to India’s treaties from FY 2020-21 onward, specifically to curb treaty abuse and aggressive tax planning structures. This does not change genuine DTAA claims but is worth being aware of if your situation involves more complex cross-border structuring.
