DTAA — How Indian Companies Can Stop Overpaying Withholding Tax in 2026

India’s Double Taxation Avoidance Agreements cover 90+ countries. Learn how to correctly claim treaty benefits, avoid the Principal Purpose Test pitfall, and stop paying more withholding tax than your treaty requires.

India’s DTAA Network — 90+ Treaties and Counting

India has one of the world’s most extensive Double Taxation Avoidance Agreement (DTAA) networks, with treaties covering over 90 jurisdictions including the United States, United Kingdom, Singapore, UAE, Germany, Japan, Mauritius, and the Netherlands. These treaties are designed to prevent the same income from being taxed in both India and the source country — and to provide predictability for cross-border investors and businesses.

Yet despite this extensive treaty network, a large proportion of Indian companies with overseas operations and foreign business relationships continue to overpay withholding tax (WHT) on cross-border payments — either because they do not proactively claim treaty benefits, or because they do not meet the procedural requirements to do so correctly.

What Does a DTAA Actually Do?

A Double Taxation Avoidance Agreement between India and another country typically provides for:

• Reduced withholding tax rates on dividends, interest, royalties, and fees for technical services — often significantly lower than domestic rates
• Definition of ‘Permanent Establishment’ (PE) — determining when a foreign company has sufficient presence in India to be taxable here
• Tax residency tie-breaker rules — for individuals and companies with residence in both treaty countries
• Capital gains taxation rules — specifying which country has the right to tax gains on transfer of shares or other assets
• Mutual Agreement Procedure (MAP) — a mechanism for resolving disputes between tax authorities of the two countries

The Real Cost of Not Claiming DTAA Benefits

Consider a common scenario: an Indian software company receives royalty income from a UK client. Under domestic Indian tax law, the UK payer would deduct WHT at 20% before remitting. However, under Article 13 of the India-UK DTAA, the applicable rate is 15% (or 10% depending on the type of royalty). The difference of 5-10% on royalty income of ₹5 crore per year represents ₹25-50 lakh in additional tax that was not required to be paid.

Multiply this across dividends from overseas subsidiaries, management fees from related parties, and interest on cross-border loans — and the total annual overpayment for a mid-size Indian group can easily reach ₹50 lakh to ₹2 crore.

How to Correctly Claim DTAA Benefits — The 6-Step Process

1. Identify the applicable DTAA: Confirm that India has a DTAA with the country from which the payment is being received or made, and verify the applicable article and rate.
2. Obtain a Tax Residency Certificate (TRC): The recipient must obtain a TRC from the tax authority of their country of residence. This is the primary evidence of treaty eligibility.
3. File Form 10F: For non-residents claiming DTAA benefits on Indian income, Form 10F must be filed with the Indian payer — an online filing with the Indian Income Tax portal.
4. Establish Beneficial Ownership: The recipient must be the genuine beneficial owner of the income — not merely a conduit or pass-through entity. Post-BEPS, this is a critical requirement.
5. Pass the Principal Purpose Test (PPT): The OECD Multilateral Instrument (MLI), which India has ratified, introduces the PPT clause into most of India’s DTAAs. If one of the principal purposes of a transaction or structure is to obtain a treaty benefit, the benefit can be denied.
6. File Form 15CA/15CB: For outbound remittances from India attracting WHT under DTAA, Form 15CA (self-declaration) and Form 15CB (CA certificate) must be filed before the remittance is made.

The Principal Purpose Test (PPT) — India’s Post-MLI Reality

Since India’s ratification of the OECD Multilateral Instrument (MLI) and its application to India’s treaty network, the Principal Purpose Test has become one of the most significant risks for cross-border structures relying on DTAA benefits. Under the PPT, if it is reasonable to conclude that obtaining a treaty benefit was one of the principal purposes of an arrangement, the benefit can be denied — even if the letter of the treaty would otherwise allow it.
