Treaties: DTAA

The India-US Tax Treaty (DTAA) Explained: Scope, Residency and Relief from Double Tax

By Abhishek Jaiin, Chartered Accountant (ICAI membership no. 544646), AU Corporate · Last updated 14 October 2026

Short answer

The India-US tax treaty (DTAA) divides taxing rights between the two countries so that income is not taxed twice. It applies to residents of either country, covers income taxes only, and lets you use the treaty or domestic law, whichever is more beneficial. Relief comes through lower Withholding Tax at source, exemptions for some income, and a foreign tax credit in the country of residence.

What a tax treaty does

Without a treaty, India taxes income arising in India, and the US taxes its citizens, residents and companies on worldwide income. The same dollar can be taxed twice. The treaty allocates which country may tax which kind of income, caps the tax a source country can charge on certain payments, and gives the country of residence the job of relieving what remains.

The treaty works alongside domestic law. Under Section 159 of the Income-tax Act, 2025 (previously Sections 90 and 90A of the 1961 Act), the Indian Act applies only to the extent it is more beneficial to the taxpayer than the treaty. A non-resident must hold a residency certificate and provide the documents the rules prescribe to claim relief.

Who and what the treaty covers

ReliefForeign tax credit in the country of residence (Article 25)

The US saving clause

The US treaty practice includes a saving clause that lets the US tax its own citizens and residents as if the treaty did not exist, with specific exceptions. This is why a US citizen working in India still files in the US and relies on the foreign tax credit or exclusions rather than treaty exemption. Your US adviser should confirm how it applies to each person.

Treaty residence for companies and individuals

  • A company is usually a resident where it is incorporated or managed, as the treaty defines. A US parent incorporated in the US is a US resident.
  • An individual who is a resident of both countries under domestic law is resolved by the tie-breaker in Article 4: permanent home, then centre of vital interests, then habitual abode, then nationality, and finally agreement between the tax authorities.
  • Treaty residence is proved with a certificate from the home tax authority. For the US this is Form 6166 issued by the IRS.

How to use the treaty in practice

  1. Confirm who the recipient is and that it is the beneficial owner of the income.
  2. Identify the type of payment: dividend, interest, royalty, fees for included services or something else.
  3. Obtain the Tax Residency Certificate and Form 41 (previously Form 10F), plus any no-PE declaration the payer asks for.
  4. The Indian payer deducts Withholding Tax under Section 393 (previously Section 195) at the treaty rate where conditions are met.
  5. The US recipient claims a foreign tax credit in its US return for Indian tax paid, under US rules.

When the two countries disagree

If you are taxed in a way that does not follow the treaty, you can ask your country's tax authority to resolve it with the other under the mutual agreement procedure (Article 27). Transfer pricing adjustments can also be dealt with this way. See tax notices and litigation.

What this means for a US parent

  • Treaty relief reduces Indian tax at source; it does not remove your US filing. Use the foreign tax credit and keep proof of Indian tax paid.
  • Treaty articles carry conditions, so confirm each claim against the treaty text and the current Indian law before relying on it.

Mistakes to avoid

  • Assuming the treaty applies automatically without documents.
  • Ignoring the beneficial ownership condition when payments pass through another entity.
  • Treating the treaty as covering social security.
  • Using a rate from a table without checking the payment category.

Frequently asked questions

What is a DTAA?

A double taxation avoidance agreement. It decides which country can tax which income and reduces tax at source on certain cross-border payments.

Does the India-US treaty replace Indian tax law?

No. It works alongside it. The Indian Act applies only to the extent it is more beneficial than the treaty (Section 159 of the Income-tax Act, 2025).

Is the treaty automatic?

No. You must prove residence, usually with a Tax Residency Certificate and Form 41 (previously Form 10F), and meet the conditions for each article.

Does the treaty cover social security tax?

No. Article 2 excludes US social security taxes from the covered taxes.

What is the saving clause?

A US treaty clause that allows the US to tax its own citizens and residents as if the treaty did not exist, subject to listed exceptions.

How is double taxation relieved?

Mainly by a foreign tax credit in the country of residence, and by lower Withholding Tax at source.

What if a tax authority does not follow the treaty?

You can request the mutual agreement procedure so that the two tax authorities resolve the case.

Is a US LLC treated as a US resident under the treaty?

It depends on how the LLC is taxed in the US. A pass-through entity needs specific analysis, so take advice before claiming treaty benefits.
