What Documents are Needed to Claim DTAA Benefits in India?

For my DTAA claim, I kept the following documents/information ready:

• Tax Residency Certificate from my country of residence
• Foreign Tax Identification Number
• Indian PAN, where applicable
• Passport and basic identity details
• Details of the Indian income for which treaty relief was being claimed
• Relevant DTAA article/rate
• Supporting documents relating to the income and TDS, where required

The exact documents can depend on the income and how the treaty benefit is being claimed.

I would also keep copies of the documents even if they are not all uploaded initially. The older Income Tax Department guidance for Form 10F specifically required supporting documents to substantiate the information furnished, and the current Form 41 framework requires the TRC and foreign TIN.

I think there are two different situations getting mixed together here.

If you are a non-resident receiving Indian income and claiming a treaty benefit, the documentation is primarily about establishing your foreign tax residency and providing the prescribed treaty information.

If you are an Indian resident who paid tax in another country and want to claim foreign tax credit in India, that's where Form 67 becomes relevant.

The Income Tax Department says Form 67 is required to claim credit for foreign tax paid outside India. It requires details of the foreign income and foreign tax, and supporting proof of payment or deduction of that foreign tax must be attached.

So Form 67 shouldn't automatically be added to every NRI's DTAA document checklist.

The most important document is generally the Tax Residency Certificate (TRC) issued by the tax authority of the country where you are tax resident.

For 2026, there is also an important change in the forms. The Income Tax Department's current guidance says Form 41 is the self-declaration used by a non-resident to claim DTAA benefits in the specified cases that were previously covered by Form 10F. The required information includes the TRC and the Tax Identification Number of the country of residence.

So I wouldn't follow an old checklist that simply says “TRC + Form 10F” without checking the current rules.

Keep your TRC valid for the relevant financial year and make sure the information you provide matches your tax-residency records.
