Double Taxation Avoidance Agreements (DTAAs) are the second-most important documents in NRI taxation — right after the Section 6 residential status determination. Get them wrong, and you can pay tax on the same income twice (in India AND in your country of residence) or claim relief you are not entitled to and face notices later. India has DTAAs with over 90 countries; this guide focuses on the three biggest NRI corridors — UK, US, and UAE — covering the rates, the documentation each treaty requires, and the procedural traps that catch most NRIs off-guard.
Why DTAA matters more than you think
Two situations where DTAA changes the outcome dramatically for NRIs:
- TDS deducted at higher Indian rate when a lower treaty rate is available — e.g. NRO interest TDS at 30% when the India-UK treaty caps it at 15%. Without claiming the treaty rate up front, you wait 12-18 months for the refund.
- Income (e.g. capital gains, dividend, royalty) being taxed in BOTH jurisdictions because the source country (India) deducted TDS and the country of residence (UK / US) also taxes worldwide income. The treaty provides relief — but only if claimed correctly via Form 67 in India / equivalent in the home country.
How DTAA actually works
Every DTAA has the same architecture — a set of Articles defining how each income type (salary, interest, dividends, royalties, capital gains, business profits, etc.) is to be taxed when income arises in one country and the recipient resides in the other. Three operative principles:
- Source-state taxing rights — the country where the income arises generally has the first right to tax (with a cap on withholding rates set by the treaty).
- Residence-state taxing rights — the country where the recipient resides usually has the right to tax worldwide income (with a credit or exemption for the source-country tax under Article 23 / 24 / 25).
- Relief mechanism — either the residence country gives a credit for the source-country tax (Form 67 in India for foreign tax paid, IRS Form 1116 in the US, HMRC Self Assessment relief in the UK), or it exempts the foreign income altogether (less common).
India-UK DTAA — key rates
The India-UK treaty was signed in 1993, amended several times. UK is one of India's biggest NRI corridors — and one with material capital gains and dividend income flowing both ways.
| Income type | Treaty rate | Documentation needed |
|---|---|---|
| Interest (including NRO) | 15% | TRC + Form 10F |
| Dividends (paid by Indian company) | 15% | TRC + Form 10F |
| Royalties | 15% / 10% | TRC + Form 10F |
| Fees for technical services (FTS) | 15% / 10% | TRC + Form 10F |
| Capital gains — immovable property in India | Taxable in India per Indian law | TRC + Form 10F (for any source-state cap) |
| Capital gains — shares of Indian company | Taxable in India per Indian law | TRC + Form 10F |
| Salary for services rendered in UK | Taxable in UK only | Form 67 to claim credit if Indian TDS deducted |
India-US DTAA — key rates
The India-US treaty is the most-used DTAA in the world by volume of taxpayers covered. Roughly 4.5 million Indian-origin US residents are potential beneficiaries. The treaty was signed in 1989 and updated periodically.
| Income type | Treaty rate | Notes |
|---|---|---|
| Interest (including NRO) | 15% | Banks need TRC + Form 10F to apply |
| Dividends from Indian company | 15% / 25% | 15% if substantial ownership; else 25% |
| Royalties | 10% / 15% | 10% for equipment royalty, 15% for general |
| Fees for technical / included services | 10% / 15% | 15% basic, lower if specific 'included services' conditions met |
| Capital gains — Indian immovable property | Taxable in India | TRC + Form 10F |
| Capital gains — Indian shares (excluding 1961 amendment categories) | Taxable in India | TRC + Form 10F |
| Salary for services rendered in US | Taxable in US only | Form 67 in India to claim credit |
US-side coordination is important — the US taxes worldwide income for citizens and green card holders. Indian-source income reported on Form 1040 with Form 1116 (Foreign Tax Credit). Where you are a US tax resident but pay Indian tax via DTAA rates, the credit usually offsets the US tax liability.
India-UAE DTAA — key rates
The India-UAE DTAA is special — UAE introduced corporate tax only in June 2023 (at 9% for businesses above AED 375,000 net profit), and personal income tax is still zero. For UAE-resident NRIs, the treaty often produces the cleanest tax outcome: low Indian withholding via the treaty, and zero UAE personal tax on the same income.
| Income type | Treaty rate | Notes |
|---|---|---|
| Interest (including NRO) | 12.5% | Lower than the 15% in many other DTAAs — meaningful saving. |
| Dividends from Indian company | 10% | Among the lowest in India's treaty network. |
| Royalties | 10% | Equipment royalty also 10% |
| Fees for technical services | 10% | Single rate (no 'included services' carve-out) |
| Capital gains — Indian immovable property | Taxable in India per Indian law | TRC + Form 10F |
| Capital gains — shares (Article 13(5)) | Article 13(5) of treaty — generally taxable in country of residence for short-period holdings (key NRI structuring point) | Specialist advice recommended |
Tax Residency Certificate (TRC)
A TRC is a document issued by the tax authority of the country where you are resident, certifying that you are a tax resident of that country during the relevant period. The Indian Income Tax Department requires it before applying any DTAA benefit (under Section 90(4)). Per-country specifics:
- UK — HMRC issues a 'Certificate of Residence' on application; online request, usually issued in 2-4 weeks. Apply for the specific year(s) of Indian income.
- US — IRS issues Form 6166 on Form 8802 application; takes 4-6 weeks (longer in tax season). Form 8802 has a $185 user fee.
- UAE — Ministry of Finance issues TRC online via the MoF portal; turnaround 1-2 weeks. Document requirements have tightened post-corporate tax introduction.
The TRC is provided to the Indian payer (bank, company, etc.) BEFORE the income is paid — so the treaty rate applies up front. Submitting the TRC after the fact does not retroactively reduce the TDS deducted.
Form 10F — the second document
From AY 2022-23, the Indian Income Tax Department requires Form 10F to accompany the TRC. Form 10F discloses information not always present on the foreign TRC — particularly the foreign tax identification number, period of residency claimed, and the address. Filed electronically by the non-resident on the Indian e-filing portal.
- Filed BEFORE the income payment is made.
- Linked to the non-resident's PAN. If the non-resident does not have a PAN, the Form 10F filing process requires alternative documentation.
- Valid for the relevant FY only — refresh annually.
- Once filed, the acknowledgement reference goes to the payer along with the TRC.
Form 67 — claiming foreign tax credit
When you ARE resident in India (ROR) and have paid tax on foreign income to a foreign country, Form 67 is the Indian-side mechanism to claim Foreign Tax Credit (FTC) under Section 90/91 read with Rule 128. Required only by Indian RESIDENTS — NRIs / RNORs do not file Form 67 on Indian-source income.
- Filed online BEFORE the ITR due date for the relevant AY.
- Reports foreign income, foreign tax paid, the treaty article relied upon, and supporting documents.
- Credit limited to the lower of foreign tax paid or Indian tax on that income.
- Excess credit cannot be refunded — only set off against Indian tax on the same income.
- Documentation: foreign tax payment proof, TRC of the foreign country, computation showing the credit calculation.
MLI — the 2017 multilateral overlay
The Multilateral Instrument (MLI) signed by India in 2017 modifies certain DTAAs without bilateral renegotiation — primarily the Principal Purpose Test (PPT), preamble language, and dispute resolution provisions. Practical effect:
- PPT — treaty benefits can be denied if obtaining the benefit was a principal purpose of the arrangement. Anti-abuse provision; rarely affects ordinary NRI use cases.
- Affects DTAAs with most major partners including India-UK (notified) and India-Singapore.
- India-US treaty NOT covered by the MLI (US has not ratified).
- India-UAE treaty NOT covered (UAE has not ratified MLI for India).
For most NRI use cases (dividend repatriation, NRO interest, capital gains repatriation), the MLI overlay does not materially change the rates. Specialist advice needed for cross-border holding structures.
Common DTAA mistakes
- Letting NRO interest TDS deduct at 30% without submitting TRC + Form 10F upfront — leads to a 12-18 month refund battle.
- Submitting TRC alone without Form 10F (post AY 2022-23 the Form 10F is also mandatory).
- Claiming treaty rate without being able to demonstrate UAE / UK / US tax residency — substance matters, paper does not survive scrutiny.
- ROR taxpayers forgetting to file Form 67 before ITR due date — Foreign Tax Credit can be denied on procedural grounds.
- Believing UAE residence automatically means India treaty rate applies — TRC + Form 10F still required, and UAE economic substance must support residency.
- Citing treaty article incorrectly (e.g. quoting Article 11 Interest when the income is actually Article 13 Capital Gains) — wrong article = wrong rate.
Frequently Asked Questions
What is DTAA and how does it help NRIs?
A Double Taxation Avoidance Agreement is a bilateral treaty between India and another country that allocates taxing rights on cross-border income. For NRIs it provides reduced withholding rates on Indian-source income (interest, dividends, royalties), and a credit mechanism in the country of residence for tax paid in India. The single biggest practical benefit: NRO interest TDS at 12.5-15% under treaty rate vs 30% under domestic Indian rate.
Do I need both TRC and Form 10F?
Yes, since AY 2022-23. The TRC is issued by the tax authority of your country of residence (HMRC for UK, IRS for US, MoF for UAE). Form 10F is filed by you on the Indian e-filing portal. Both must be provided to the Indian payer BEFORE the income payment for the treaty rate to apply.
How do I get a TRC from the US (IRS Form 6166)?
File Form 8802 with the IRS. There is a $185 user fee. Processing time is 4-6 weeks normally; longer during US tax season (Jan-April). Apply for the specific calendar year(s) of Indian income. Form 6166 is the residency certificate itself.
What is the DTAA rate for NRO interest under the India-UK treaty?
15%, vs 30% under domestic Indian rate. The treaty rate applies only if the NRI submits a valid UK Certificate of Residence (TRC) and Form 10F to the Indian bank before interest is credited. Without these documents, the bank must deduct TDS at the higher domestic rate.
Does India have a treaty with UAE despite UAE having no personal income tax?
Yes — the India-UAE DTAA is in force and has been used extensively. UAE residence is determined by the UAE Ministry of Finance criteria (typically minimum 183 days, evidence of economic substance, etc.). Once UAE residency is established and a TRC issued, treaty rates apply to Indian-source income — even though UAE personal tax is zero on that income.
What is Form 67 and when is it needed?
Form 67 is the Indian filing for Foreign Tax Credit under Section 90/91. It is needed when you are a RESIDENT in India (ROR) and have paid foreign tax on foreign income. NRIs and RNORs typically do not file Form 67 because their foreign income is not taxable in India in the first place. Filed online BEFORE the ITR due date.
