Double Taxation Avoidance Agreements (DTAAs) are bilateral treaties between two countries designed to prevent the same income from being taxed twice, once in the source country (where the income originates) and once in the residence country (where the taxpayer lives). For the millions of Non-Resident Indians earning income in India while residing abroad, DTAAs are a critical tool for minimising overall tax burden and ensuring fair treatment across jurisdictions. India has signed DTAAs with over 90 countries, covering virtually every major NRI destination.

How DTAA Works: The Fundamental Mechanism

DTAAs work through two primary methods of relief. The exemption methodallows income to be taxed in only one of the two countries. The credit method(more common in India's treaties) allows both countries to tax the income but provides a credit in the residence country for taxes paid in the source country, ensuring the total tax does not exceed the higher of the two countries' rates. India primarily uses the credit method through Section 90 (for countries with which India has a DTAA) and Section 91 (unilateral relief for countries without a DTAA).

Under Section 90, the taxpayer can choose to be taxed under the provisions of the Income Tax Act or the DTAA, whichever is more beneficial. This is a fundamental right, and the tax authorities cannot force a taxpayer to use the less favourable provision. This choice can be made on a source-by-source basis, meaning you can claim DTAA benefit for interest income while being taxed under domestic law for capital gains if that combination yields the lower overall tax.

Key DTAA Rates by Country

Each DTAA specifies maximum tax rates that the source country can charge on different types of income. These rates vary significantly between treaties. For interest income, most of India's DTAAs cap the source country tax at 10-15%. The India-UAE DTAA offers one of the most favourable rates at 12.5%. For dividend income, rates range from 10% (UAE, Singapore) to 25% (USA, Canada). Royalty income is typically capped at 10-15%. Capital gains treatment varies most significantly: some treaties exempt capital gains from source country taxation entirely (for specific asset types), while others maintain full taxing rights for the source country.

The Most-Favoured-Nation (MFN) Clause

Several of India's DTAAs include a Most-Favoured-Nation (MFN) clause, which states that if India signs a more favourable treaty with another OECD member country in the future, the lower rate automatically applies to the existing treaty as well. This clause was particularly relevant for treaties with France, the Netherlands, and other European countries. However, the Supreme Court of India in the Nestle SA case (2023) ruled that MFN clause benefits do not apply automatically and require a separate notification by the Indian government. This significantly impacts NRIs relying on MFN provisions and underscores the importance of staying current on treaty interpretation.

Claiming DTAA Benefits: Documentation Requirements

To claim DTAA benefits in India, the following documentation is essential:

• Tax Residency Certificate (TRC): Issued by the tax authority of your country of residence. This is the primary document proving you are a tax resident of the treaty partner country.
• Form 10F: A self-declaration form submitted to the Indian tax authorities containing details required under Rule 21AB, including name, status, nationality, and address in the country of residence.
• PAN (Permanent Account Number): NRIs must have a valid PAN to file returns and claim treaty benefits.
• No Permanent Establishment (PE) certificate: For business income, a declaration that the NRI does not have a PE in India.

Without these documents, the payer (bank, mutual fund, or property buyer) is required to deduct TDS at domestic rates, which are typically higher than DTAA rates. Obtaining a TRC can take 2-6 weeks depending on the country, so NRIs should plan ahead, especially before selling property or redeeming large investments in India.

Foreign Tax Credit (FTC) under Rule 128

The Foreign Tax Credit mechanism allows taxpayers to claim credit in India for taxes paid in a foreign country on the same income. Under Rule 128 of the Income Tax Rules, the FTC is limited to the lower of the tax paid abroad and the Indian tax payable on that income. The credit must be claimed in the year the income is offered for taxation in India, and Form 67 must be filed before the due date of the income tax return. Failure to file Form 67 on time has been a contentious issue, with some tribunals allowing belated filing while others have denied the credit.

Common DTAA Scenarios for Indian NRIs

NRI in the USA earning FD interest in India: Without DTAA, TDS is deducted at 30% on NRO FD interest. Under the India-USA DTAA, the rate is capped at 15%. The NRI can submit TRC and Form 10F to the bank to get TDS at 15% instead of 30%, saving half the withholding tax. The interest is also reportable in the US tax return, where a credit is available for the Indian tax paid.

NRI in the UAE selling property in India: The India-UAE DTAA provides that capital gains from immovable property can be taxed in the country where the property is situated (India). So the DTAA does not provide exemption from Indian capital gains tax on property. However, since UAE has no income tax, there is no double taxation in practice. The NRI must still comply with Indian TDS requirements.

NRI in the UK receiving dividends from Indian companies: Under the India-UK DTAA, dividend tax is capped at 15%. India deducts TDS at this rate, and the UK provides a credit for this tax against the UK tax liability on the same dividend income. The effective tax is the UK rate (higher of the two), with no double taxation.
