Double Taxation Avoidance Agreement (DTAA)

By Manu Rao | Updated March 2026

What Is a DTAA?

A Double Taxation Avoidance Agreement is a tax treaty between two countries. Its purpose is simple: prevent the same income from being taxed twice. Without a DTAA, a US citizen earning dividends from an Indian company would pay Indian withholding tax and then US income tax on the same money — with no relief.

India has signed DTAAs with over 90 countries. These agreements are negotiated based on the OECD Model Tax Convention or the UN Model Tax Convention, though each treaty has country-specific provisions.

Legal Basis

India's authority to enter into DTAAs comes from Section 90 of the Income Tax Act, 1961. Section 90(1) empowers the Central Government to enter agreements with other countries to grant relief from double taxation. Section 90(2) specifies that where India has a DTAA with a country, the taxpayer can be taxed under the provisions of the Act or the DTAA, whichever is more beneficial.

This "more beneficial" provision is critical. It means that if the DTAA rate is lower than the domestic rate, the foreign investor can claim the lower rate.

Key related provisions:

• Section 90(4) — To claim DTAA benefits, the non-resident must obtain a Tax Residency Certificate (TRC) from the tax authority of their home country
• Section 90(5) — The non-resident must also provide Form 10F with certain specified information
• Rule 21AB — Prescribes the format and content requirements for TRC

How DTAAs Affect Foreign Investors in India

DTAAs impact several types of income that a foreign investor in India might earn:

Dividend Income

India imposes 20% withholding tax on dividends paid to non-residents (Section 196D read with Section 115A). But DTAAs often reduce this:

Interest Income

The domestic withholding rate on interest paid to non-residents is 20% under Section 195. DTAAs often bring it down to 10-15%.

Royalties and Fees for Technical Services

Domestic rate is 10% under Section 115A (as amended by Finance Act 2023). Some older DTAAs set the rate at 10-15%, while a few have higher thresholds.

Capital Gains

This is where DTAAs become most important. Capital gains from selling shares in an Indian company are taxable in India — short-term at 15% (listed) or normal slab rates (unlisted), long-term at 10-12.5%. Some DTAAs give the right to tax capital gains only in the investor's home country, creating significant tax savings.

The India-Mauritius and India-Singapore DTAAs were historically used for capital gains exemption, but amendments in 2017 (Mauritius, effective April 1, 2017) and 2005 Protocol (Singapore) now tax capital gains in India for shares acquired after April 1, 2017.

How to Claim DTAA Benefits

Claiming DTAA benefits is not automatic. Follow these steps:

1. Obtain a Tax Residency Certificate (TRC) from the tax authority of your home country. In the US, the IRS does not issue TRCs directly — you use Form 6166. In the UK, HMRC issues a Certificate of Residence.
2. File Form 10F with the Indian tax authority (can be filed electronically on the income tax portal). This declares your status, nationality, tax ID, and the period for which DTAA benefit is claimed.
3. Provide TRC and Form 10F to the payer (the Indian company paying dividends/interest). The Indian company then deducts tax at the DTAA rate instead of the domestic rate.
4. Claim credit in your home country. If your home country taxes worldwide income, you can usually claim a foreign tax credit for the Indian tax paid.

Countries Without DTAA With India

Not all countries have treaties with India. Notable gaps include:

• Nigeria — No DTAA. Full domestic withholding rates apply (20% on dividends, 20% on interest).
• Argentina — No DTAA.
• Several African and Central American nations

For investors from non-DTAA countries, Section 91 of the Income Tax Act provides unilateral relief — India grants a deduction for the tax paid in the other country, even without a treaty. But this relief is less generous than DTAA provisions.

Common Mistakes

• Not getting the TRC before the payment date. The TRC must cover the period in which the income is earned. Retrospective TRCs are not always accepted.
• Confusing tax residency. A US green card holder living in Dubai is a US tax resident, not a UAE tax resident. The DTAA that applies depends on where you are tax-resident, not where you live or hold citizenship.
• Ignoring the Most Favoured Nation clause. Some DTAAs (like India-Netherlands) have MFN clauses that can reduce rates further if India signs a more favorable treaty with another OECD country. The Supreme Court addressed this in Nestle SA (2023).
• Treaty shopping without substance. Setting up a shell company in Mauritius or Singapore just to claim DTAA benefits, without any real business activity there, is treaty shopping. The General Anti-Avoidance Rules (GAAR), effective April 1, 2017, allow Indian tax authorities to deny treaty benefits in such cases.
• Forgetting to file Form 10F. Since April 2023, Form 10F must be filed electronically. Many non-residents miss this step and face higher withholding.

Practical Example

Hans, a German citizen and tax resident, owns 30% of an Indian Private Limited Company through FDI. The company declares a dividend of Rs 50 lakh.

Without the DTAA, India would withhold 20% — Rs 10 lakh. But the India-Germany DTAA (Article 10) reduces the rate to 10% for dividends where the beneficial owner holds at least 10% of the paying company.

Hans provides his TRC from the German Federal Central Tax Office and files Form 10F. The Indian company withholds only 10% — Rs 5 lakh — and remits Rs 45 lakh to Hans through the AD bank.

In Germany, Hans reports the dividend as worldwide income. Germany taxes it at his applicable rate but gives a credit for the Rs 5 lakh Indian tax paid. No double taxation occurs.

Key Takeaways

• India has DTAAs with 90+ countries — always check before investing
• Section 90(2) of the Income Tax Act gives you the right to use whichever rate is lower (domestic or DTAA)
• TRC + Form 10F are mandatory to claim treaty benefits
• Capital gains treatment varies widely by treaty — the Mauritius/Singapore exemption ended for post-2017 investments
• GAAR can deny benefits if the arrangement lacks commercial substance
