Form 10F: The 5-Minute Form That Can Save You Lakhs

Form 10F (Form 41 from 1 April 2026 under the Income-tax Act 2025) is a Rule 21AB / Rule 75 self-declaration filed on incometax.gov.in. It accompanies the TRC. Without it, the deductor must withhold at the Section 195 default of 30% even where a valid TRC is on file.

The form captures the country-of-residence Tax Identification Number, the period the TRC covers, the foreign address, and the DTAA article being claimed (Article 11 for interest, Article 10 for dividends, Article 13 for capital gains). The CBDT cross-references these against the TRC at processing.

The filing is e-verified via Aadhaar OTP or DSC and takes roughly five minutes once the TRC is in hand.

1. Log into incometax.gov.in with PAN credentials

2. Navigate to e-File, then Income Tax Forms, then File Form 10F

3. Select the assessment year (AY 2026-27 for FY 2025-26 income)

4. Complete the seven mandatory fields:

• Name (as on PAN)

• Status: Individual

• Nationality: Indian

• Country of residence: [your country]

• Tax Identification Number issued by that country

• Period of residential status: the financial year covered by the TRC

• Address in the foreign country

5. e-Verify via Aadhaar OTP or DSC

6. Download the acknowledgement PDF for the NRI cell at the bank / AMC

From 1 April 2026, the same data set moves to Form 41 under the Income-tax Act 2025, the workflow on the portal is unchanged.

Mistake 1: Assessment year mismatch. TDS deducted in FY 2025-26 reports against AY 2026-27. A Form 10F filed under the wrong AY will not link to the ITR at CPC processing. The refund claim sits unverified and the AO eventually issues a Section 143(1)(a) intimation asking for the linkage.

Mistake 2: TIN mismatch with the TRC. The Tax Identification Number on Form 10F must be identical to the one on the TRC, SSN or ITIN for the US, UTR for the UK, FIN for Singapore, SIN for Canada. CPC matches character-by-character.

Mistake 3: Leaving the TIN box blank because your country does not issue one. The Gulf states levy no personal income tax and issue no tax ID to individuals, which stops a lot of people here. The form already answers it. Field (iv) asks for your tax identification number and, if there is no such number, then a unique number on the basis of which the person is identified by the Government of that country. So your Emirates ID, CPR, QID, Civil ID or Iqama number is what belongs in that box. It is the correct entry, not a workaround, and a blank field is what gets the claim rejected.

Mistake 4: Sequencing. Form 10F must precede or accompany the ITR, not follow it. A return filed before the 10F acknowledgement number can be referenced gets routed to manual processing and adds 60-90 days to the refund cycle.

Mistake 5: Skipping the form on the assumption that a TRC alone unlocks the rate. The deductor's NRI cell requires both documents on file before applying the treaty rate to a subsequent credit. TRC without Form 10F = continued Section 195 withholding at 30%.
