India Tax Treaties, Form 10F and Tax Residency Certificate (TRC) Explained

A non-resident who earns income from India does not get tax treaty relief automatically. To use an India tax treaty (a double taxation avoidance agreement, or DTAA), the payee must hold a tax residency certificate (TRC) from the home country and furnish Form 10F, which the Income-tax Rules, 2026 renumbered as Form 41. Without them, the Indian payer must withhold at the ordinary rate. This guide explains the documents, the online steps and the treaty ceilings that matter to U.S. and Canadian residents.

What is Form 10F and who files it?

Form 10F is a self-declaration that backs a treaty claim. The Department's FAQ says it is filed by non-resident individuals, companies and other entities that receive income from India and want DTAA benefits, including those who have no PAN or no obligation to file an Indian return but whose payment is subject to TDS. It is mandatory. It is not due on a fixed date; it is needed whenever a claim is made, and a new form is needed for each tax year.

Under the Income-tax Act, 2025, the rule is section 159(8): a non-resident can claim relief under an agreement only if they obtain a certificate of residence from their home government and provide the other documents and information prescribed. Rule 75 of the Income-tax Rules, 2026 prescribes Form 41 and requires the assessee to keep the documents that substantiate it. Section 159(4) adds that the Act's provisions apply where they are more beneficial than the treaty. For earlier periods the same system ran under rule 21AB of the 1962 Rules and Form 10F.

How to file Form 10F or Form 41, step by step

1. Pick the treaty and the article. Dividends, interest, royalties, fees for included services, business profits and capital gains each have their own article.
2. Get the tax residency certificate for the right year. U.S. residents request Form 6166 by filing Form 8802; the IRS explains it is a letter certifying U.S. residency for treaty claims. Canadian residents request a certificate of residency from the Canada Revenue Agency. The certificate must cover the relevant financial year.
3. Collect your tax identification number (TIN) in the country of residence.
4. Register on the e-Filing portal. Non-residents without a PAN register under the category created for them. You cannot file offline.
5. Fill and submit the form online, uploading the TRC. Information includes status, country of residence, TIN, the period covered by the certificate, and your overseas address. No proof of tax payment is needed, and Aadhaar is not asked for.
6. Verify. Use an electronic verification code or a digital signature, or, for non-residents without PAN, OTPs to your phone and email. Once an acknowledgement is generated, the form cannot be edited.
7. Give the acknowledgement and TRC to the Indian payer and keep the supporting file. Payers often add their own requests, such as a beneficial ownership or no-permanent-establishment declaration.

Why the form matters

The Department's FAQ is direct: without a valid, electronically filed form along with the TRC and other documents, the DTAA benefit is not available. The payer must then deduct tax at the applicable rate, and income claimed as exempt in the Indian return is taxed at ordinary rates. See TDS and TCS for businesses for the payer's side.

Treaty ceilings under the India-US treaty

The text of the 1989 India-US treaty, as published by the IRS, sets these maximum rates in India for beneficial owners who are U.S. residents:

The treaty defines "royalties" and "fees for included services" narrowly, and later protocols, domestic changes and anti-abuse rules can alter outcomes. Check the current text with your Indian Chartered Accountant (CA). Our US-India treaty guide and India-Canada treaty guide go further.

Indian residents who need an Indian certificate

An Indian resident who needs proof of residence for a foreign treaty claim applies to the Assessing Officer on Form 42, and the officer issues the certificate on Form 43 under rule 75. Disputes under a treaty can go to the mutual agreement procedure, which uses Form 55 for resident assessees.

A worked example

A Wheaton consultant bills an Indian company Rs 20,00,000 for technical services during FY 2026-27. She files Form 8802 and receives Form 6166, registers on the e-Filing portal, and submits Form 41 with the TRC before the first payment. If the services qualify as fees for included services, the treaty ceiling of 15% limits Indian tax to Rs 3,00,000. If she had skipped the form, the payer would have to withhold at the full domestic rate, and she would be left to recover any excess through an Indian return.

Documents and information you need

• A tax residency certificate for the relevant year, with your TIN and the period it covers
• Your legal name, status (individual, company or other), country of residence and overseas address
• An e-Filing portal login, with a mobile number and email address that can receive OTPs
• Contracts or invoices linking each payment to a treaty article, plus any payer-specific declarations
• Records of earlier forms, so the file shows the same facts year after year

Mistakes to avoid

• Using a TRC for the wrong year or one without a TIN
• Assuming a treaty rate applies automatically without the form
• Forgetting to renew the form each tax year
• Filing after the payer has already withheld, then discovering the delay costs cash
• Ignoring the U.S. side, where Indian tax paid may create a foreign tax credit
