India has DTAA (Double Tax Avoidance Agreement) with 90+ countries — USA, UK, UAE, Singapore, Canada, Germany, Australia, and most major economies. DTAA works through two different mechanisms depending on the income type:

Mechanism 1 — Reduced Rate (Most Common for NRIs)

For interest, dividend, and royalty income — DTAA prescribes a specific lower tax rate between the two countries. India taxes the income, but at the DTAA rate instead of the domestic rate. The difference is the saving.

Example: NRO interest — domestic rate 30%. India-USA DTAA — 15%. NRI submits TRC + Form 10F → bank deducts at 15% → saving 15% on every rupee of interest.

Mechanism 2 — Tax Credit / Exemption (For Capital Gains)

For India-sourced capital gains (Indian listed shares, Indian property) — India retains the primary taxing right. DTAA does not reduce India’s tax. Instead, the mechanism works in your residence country: you pay full Indian capital gains tax, then claim it as Foreign Tax Credit in your residence country’s tax return — so you are not taxed twice on the same income.

Note: Exact DTAA rates depend on the specific treaty article and income classification. Verify with a CA for your country’s current treaty provisions before relying on these figures.

TRC (Tax Residency Certificate) is issued by the tax authority of your country of residence. It confirms that you are a tax resident of that country for the specified period. Without TRC — no DTAA benefit is valid. TRC is the foundational document.

What If TRC Is Delayed?

If TRC does not arrive before bank’s first TDS deduction — let the bank deduct at domestic rate (30%). Once TRC is received — submit it to the bank along with Form 10F for the remaining year’s payments. For the months already taxed at 30% — claim the DTAA refund via ITR filing at year end. Do not miss the ITR filing deadline (August 31 — Budget 2026 update) waiting for TRC. File on time, claim DTAA benefit in Schedule TR, and receive refund after processing.

Form 10F is an additional self-declaration required under Rule 21AB of the Income Tax Act. It supplements the TRC by providing specific details that most foreign TRCs do not contain in the format India requires: the NRI’s tax identification number in the residence country, their address there, the period of residence, and their Indian PAN.

Why Both TRC and Form 10F Are Needed

TRC proves you are a tax resident of the other country. Form 10F provides the additional specific information required by Indian law to process the DTAA claim. One without the other is insufficient — the deductor (bank) will not apply DTAA rates, and the ITR claim may be questioned without both.

How to File Form 10F (Online — Mandatory Since 2023)

1. Log in to incometax.gov.in using your PAN credentials
2. Navigate to: e-File → Income Tax Forms → File Income Tax Forms
3. Search for Form 10F and select the applicable assessment year
4. Fill in: Country of residence, Tax Identification Number (TIN) in residence country, your address abroad, the period for which you claim resident status, and nationality
5. Upload TRC as supporting document
6. Submit — an acknowledgment number is generated. Save this acknowledgment.

Example 1 — USA NRI: ₹93,600 Annual Saving on NRO Interest

Rahul submits IRS Form 6166 + Form 10F to his bank every April. Bank applies 15% rate throughout the year. Zero excess TDS. Zero refund needed. The ₹93,600 stays in his NRO account, not with the government.

Example 2 — UK NRI: Dividend Saving

Mrs. Sharma submits HMRC Certificate of Residence + Form 10F to her broker/company in April. The broker deducts at 15% DTAA rate on dividend payments. Over 10 years with growing dividend portfolio — cumulative saving: ₹1,04,000+.

Example 3 — UAE NRI: TRC Delayed, Refund Route

Mr. Khan in UAE. His TRC from FTA arrived late (June, not April). Bank had already deducted 30% TDS on April and May interest (₹40,000 excess TDS for two months).

Action taken: Submitted FTA Tax Domicile Certificate + Form 10F to bank in June. Bank applied 12.5% DTAA rate from June onwards. For April-May excess TDS — filed ITR by August 31, declared NRO interest in Schedule OS, claimed DTAA in Schedule TR (Article 11 of India-UAE treaty). Refund of ₹40,000 received after ITR processing.

Key lesson: Missing the April TRC window does not mean losing the DTAA benefit entirely. Submit when available, deduct at DTAA rate going forward, claim prior months’ excess via ITR. Never miss the ITR deadline waiting for TRC.

Even if the bank deducts TDS at DTAA rate, the ITR must formally claim the DTAA benefit in Schedule TR (Tax Relief). This confirms the treaty position and reconciles with AIS data.

What to Fill in Schedule TR

• Country: Name of country with which DTAA is being claimed (USA, UK, UAE etc.)
• Article Number: The specific article in the DTAA that covers your income type. For interest — typically Article 11. For dividends — typically Article 10. For royalties — Article 12. Verify the exact article in your country’s specific DTAA text.
• Income: Amount of income on which DTAA is being claimed (NRO interest, dividend amount etc.)
• Tax paid in India: TDS deducted — whether at DTAA rate or domestic rate
• Relief claimed: The difference between domestic rate tax and DTAA rate tax — this is your refund claim
• Section: Section 90 (if bilateral DTAA with notification) or Section 90A (if multilateral instrument)

1. 1Apply for TRC in February/March
   Contact your country’s tax authority (IRS, HMRC, FTA, CRA, IRAS) and request a Tax Residency Certificate for the Indian financial year (April to March). Allow processing time — 2–6 weeks depending on country. USA NRIs: IRS Form 6166 takes the longest — apply in February.
2. 2File Form 10F Online
   Log in to incometax.gov.in → e-File → Income Tax Forms → Form 10F. Fill all required fields. Upload TRC. Submit. Save the acknowledgment number. This can be done as soon as TRC is received.
3. 3Submit Both Documents to Bank/Deductor
   Submit TRC (original or certified copy) + Form 10F acknowledgment to your bank (NRO account branch), broker, or any other deductor at the start of the financial year. Banks typically accept these by email to the NRI desk or in-branch. Request written confirmation that the DTAA rate has been updated in your account.
4. 4Verify AIS After First TDS Deduction
   After the first TDS deduction of the year (typically April/May) — log in to incometax.gov.in and check AIS to confirm TDS is being deducted at the DTAA rate. If still showing at 30% — follow up with bank immediately and resubmit documents if needed.
5. 5File ITR with Schedule TR
   In ITR-2 — fill Schedule TR with country, DTAA article, income amount, and tax paid. Even if DTAA rate was correctly applied at source — Schedule TR formally confirms the treaty position. File before August 31 (Budget 2026).
6. 6If Excess TDS Was Deducted
   If domestic rate (30%) was deducted despite submitting documents — or before documents were submitted — claim the refund via ITR. Declare income in Schedule OS (Other Sources), claim DTAA rate in Schedule TR, and the excess TDS shows as refund. Pre-validate NRO account on IT portal for refund credit.

Mistake 1 — Submitting only TRC, not filing Form 10F: The most common error. TRC proves residency. Form 10F provides the additional specific details India requires. Submitting TRC to the bank without separately filing Form 10F online makes the claim incomplete. The bank may still deduct at 30% — or accept for the year, only for the ITR claim to be questioned. File both — they are separate steps.

Mistake 2 — Not filing Schedule TR in ITR: Collecting TRC and Form 10F, submitting them to the bank, but not filling Schedule TR in the ITR. The ITR is the formal claim — without Schedule TR, the DTAA benefit is not formally recorded in the tax system. Always fill Schedule TR in ITR-2, even if TDS was correctly deducted at DTAA rate at source.

Mistake 3 — Using last year’s TRC for the current year: TRC is year-specific. A TRC for FY 2024-25 does not cover FY 2025-26 income. Apply fresh every year. Banks that do not notice may process it — but the DTAA claim can be questioned if scrutiny reveals the TRC year does not match the income year.

Mistake 4 — Wrong DTAA article number in Schedule TR: Each income type has a different article in the DTAA. Interest — typically Article 11. Dividends — Article 10. Royalties — Article 12. Using the wrong article number causes mismatches that lead to processing queries. Verify the correct article in your specific country’s DTAA text — or ask your CA to confirm before filing Schedule TR.

Mistake 5 — Believing DTAA eliminates all Indian tax: DTAA reduces certain income taxes (interest, dividend) to the treaty rate. For India-source capital gains — India’s primary taxing right means DTAA does not reduce Indian tax. The benefit for capital gains is a Foreign Tax Credit in your residence country — not a reduced Indian rate. Misunderstanding this leads to incorrectly filed returns and subsequent notices.

Mistake 6 — Missing ITR deadline waiting for TRC: TRC delayed — ITR deadline approaching — NRI waits. The filing deadline passes — capital loss carry-forward is lost, refund claim is delayed, and the ITR is now belated. Correct approach: file ITR on time at domestic rates. When TRC arrives — file a revised return (Budget 2026: until March 31) with DTAA claim in Schedule TR. The refund adjusts. Never miss the original deadline for a document that can be obtained later.
