Form 10F

Form 10F is the Income Tax Department’s prescribed self-declaration that non-residents file to claim Double Taxation Avoidance Agreement benefits in India. Issued under Rule 21AB(1) of the Income Tax Rules, it supplements the Tax Residency Certificate from the non-resident’s home country by supplying particulars that the TRC may not contain. Since CBDT Notification No. 3/2022 dated 16 July 2022, Form 10F must be e-filed on the Income Tax e-filing portal — paper Form 10F is no longer accepted.

What is Form 10F?

A foreign Tax Residency Certificate, on its own, may not contain every detail Indian rules require to validate a DTAA claim. Rule 21AB(1) lists the particulars that an acceptable TRC must contain — name, status, nationality or country of incorporation, PAN, period of residency, address abroad and tax identification number in the source country. When the foreign TRC omits any of these, Rule 21AB(2) allows the non-resident to supply the missing information through a self-declaration in Form 10F.

In practice, almost every foreign TRC is incomplete from the Indian perspective. The US IRS Form 6166, the UK HMRC residence certificate, the Singapore IRAS certificate and most others are designed for the issuing country’s domestic purposes and don’t include every Indian-mandated field. So Form 10F has become a near-universal requirement for non-residents claiming any DTAA benefit on Indian-source income.

Mandatory E-Filing — CBDT Notification 03/2022

The shift from paper to e-filing is governed by CBDT Notification No. 3/2022 dated 16 July 2022, issued by the Directorate of Income Tax (Systems), New Delhi under powers conferred by Rule 131(1)/(2) of the Income-tax Rules. The notification mandated that Form 10F be furnished electronically through the Income Tax e-filing portal for all non-residents claiming DTAA benefits.

The immediate practical issue was that e-filing requires login on the Indian e-filing portal, which in turn requires a PAN. Non-residents earning small one-off Indian income — say, a foreign expert paid USD 5,000 for a single consulting engagement — found themselves forced to apply for a PAN solely to file Form 10F. CBDT acknowledged this hardship and issued relaxations:

• CBDT Notification No. 03/2023 dated 28 March 2023 allowed non-residents without PAN, who were not otherwise required to obtain PAN, to file Form 10F manually until 31 March 2023
• That relaxation was extended in subsequent notifications, ultimately settling on a workflow where non-residents without PAN can register on the e-filing portal using their tax identification number from the home country and file Form 10F electronically without first obtaining a full PAN

The current position is that e-filing is mandatory for non-residents who have or are required to have an Indian PAN, and is the standard route for almost all others through the portal’s non-resident registration flow.

Who Needs to File Form 10F

Any non-resident who:

1. Receives income from India chargeable to tax under the Income Tax Act, and
2. Wants to claim relief under a DTAA between India and their country of residence, and
3. Has a TRC that does not contain all the particulars listed in Rule 21AB(1)

must file Form 10F. This covers:

• Foreign companies receiving royalty, fees for technical services, dividends or interest from Indian payers
• Non-resident individuals receiving Indian professional fees, salary or other Indian-source income
• Non-resident investors earning capital gains on Indian shares or property
• Foreign service providers, consultants, agencies invoicing Indian clients

Form 10F is filed once per financial year per non-resident, typically before the first payment from an Indian source in that year.

Process: How to File Form 10F

The end-to-end e-filing process:

1. Register on the Income Tax e-filing portal (incometax.gov.in) — non-residents with PAN log in normally; non-residents without PAN use the dedicated non-resident registration flow with their home country tax identification number
2. Navigate to e-File → Income Tax Forms → File Income Tax Forms → Form 10F
3. Select the financial year for which residency is being declared
4. Fill in the prescribed particulars:
   • Name and status (individual, company, firm)
   • Nationality / country of incorporation
   • PAN or alternative identification
   • Tax identification number in the country of residence
   • Period for which residential status is claimed (e.g., 1 April 2026 to 31 March 2027)
   • Address in the country of residence
5. Attach a copy of the TRC issued by the home country tax authority
6. Verify using DSC (entities) or EVC (individuals)
7. Submit and download the acknowledgement
8. Provide the acknowledgement to the Indian payer along with the TRC

The Indian payer (or the payer’s chartered accountant when issuing Form 15CB) verifies the Form 10F acknowledgement and TRC before applying the DTAA rate.

Common Errors and Consequences

• Filing on paper: Since 16 July 2022, paper Form 10F is treated as no Form 10F. The DTAA claim collapses.
• Form 10F filed for wrong financial year: A Form 10F filed for FY 2025-26 cannot be relied on for a payment made in FY 2026-27. A fresh filing is required each year.
• TIN of source country missing or wrong: The Indian portal validates the format. A wrong TIN is a structural error and the form is rejected.
• PAN mismatch: Where the non-resident has an Indian PAN, the Form 10F must be filed under that PAN. Filing under the temporary identification when a PAN exists creates a mismatch.
• No supporting TRC: Form 10F is a supplement to the TRC, not a replacement. If the TRC itself is missing or stale, Form 10F cannot rescue the DTAA claim.
• Higher TDS rate triggered: Without valid Form 10F + TRC, the deductor must apply the higher of the Income Tax Act rate or 20% under Section 195. If PAN is also missing, Section 206AA can push it further. The deductee then pursues a refund through Indian return filing — a year-long round trip that defeats the purpose of treaty rates.
• Disallowance under Section 40(a)(i): If the Indian deductor applies the lower DTAA rate without a valid Form 10F and is later assessed as having short-deducted, the entire payment can be disallowed as a deduction in the deductor’s hands.

Practical Example

A Mumbai fintech company pays USD 30,000 (₹25,50,000 at ₹85/USD) to a Canadian software architect for system design in May 2026. The architect is a Canadian tax resident.

Documentation collected:

1. Canadian TRC issued by the Canada Revenue Agency, valid for calendar year 2026 — but the certificate doesn’t list the architect’s tax identification number in the format Indian rules expect, doesn’t confirm the FY 2026-27 period explicitly, and doesn’t include nationality
2. Form 10F: the architect e-files on the Indian Income Tax portal — using the non-resident registration flow because they don’t have an Indian PAN — declaring status (individual), nationality (Canadian), Canadian Social Insurance Number as the home country TIN, period 1 April 2026 to 31 March 2027, and Canadian address
3. PAN: not available — but the architect provides the Rule 37BC alternative documentation (name, email, phone, address, TRC, TIN)
4. No-PE declaration: confirming no fixed place of business in India

The Indian payer’s CA issues Form 15CB certifying the India–Canada DTAA Article 12 rate of 10%. The payer files Form 15CA Part C, withholds ₹2,55,000, remits ₹22,95,000 net via SWIFT, and reports the deduction in the Q1 Form 27Q by 31 July 2026.

Without the e-filed Form 10F, the CA could not have certified the 10% DTAA rate. Withholding would have defaulted to 20% under Section 195, increasing the deduction to ₹5,10,000 — and the architect would have been forced to file an Indian return in 2027 to claim the ₹2,55,000 refund.

How Omnivoo Handles Form 10F

For employers paying international contractors and vendors through Omnivoo, the platform proactively requests Form 10F at the start of every financial year, validates the e-filing acknowledgement against the Income Tax portal, links it to the corresponding TRC, and feeds the documentation into the Form 15CB certification and Form 15CA filing for each remittance — eliminating the manual chase that typically delays cross-border payments.
