Why Does Double Taxation Happen?
Most NRIs in the UK still have financial ties to India. Fixed deposits, rental property, equity holdings, mutual funds, the list is usually longer than people expect. India taxes income that originates within its borders. The UK taxes income received or remitted by its residents. When both conditions apply to the same income, you end up with two tax demands on one earning.
This is not a rare edge case. For most UK-based NRIs, it is a routine situation that needs active management, not passive hope that one country will simply let it go.
What Double Taxation Relief Does
Double Taxation Relief, commonly called DTR, is not a loophole or a special concession. It is a structured legal framework under which India and the UK have formally agreed not to tax the same income twice.
The India-UK Double Taxation Avoidance Agreement, signed on 26 October 1993, is the treaty that governs this arrangement. On the Indian side, Sections 90, 90A, and 91 of the Income Tax Act 1961 give domestic legal backing to the treaty provisions.
Relief is delivered through three routes:
- Tax Credit Method: You pay tax in one country and claim that payment as a credit against your liability in the other. You do not escape tax, but you do not pay double either.
- Exemption Method: Certain income types are fully exempt from tax in one of the two countries, so only one jurisdiction collects.
- Tax Sparing Credit: Where one country has offered a tax incentive and reduced or waived its own tax, the other country still allows a credit as though the full tax had been paid. This protects the benefit of the incentive rather than simply transferring it.
Which method applies to your situation depends on what type of income you are dealing with and what the treaty says about that specific category.
Claiming Double Taxation Relief
Relief does not arrive automatically when you file your returns. You have to claim it, and the process has specific requirements that cannot be skipped.
-
Getting a Tax Residency Certificate
This is the foundational document. A Tax Residency Certificate, or TRC, is issued by His Majesty’s Revenue and Customs (HMRC) in the UK and formally confirms your tax residency status. Without this, your claim will not be processed in India. The TRC must be valid for the relevant assessment year.
-
Filing Form 10F in India
If your TRC does not contain all the details prescribed under Indian tax rules, you must file Form 10F on the Indian Income Tax portal. This is an electronic filing requirement and must be completed before your return is submitted. It fills in the information gaps that some TRCs leave out.
-
Submitting Form 67 for Tax Credits
If you are claiming a credit in India for taxes already paid to His Majesty’s Revenue and Customs (HMRC), Form 67 is mandatory. It must be filed before you submit your Indian Income Tax Return. This form sets out the foreign tax paid and formally initiates the credit claim under Section 90.
-
Claiming Relief on the UK Side
His Majesty’s Revenue and Customs (HMRC) has its own process. You fill in Form DT-Individual to claim relief on Indian-sourced income that has already been taxed there. Section 3(a) of the form covers full relief and 3(b) covers partial relief. Keep your original tax vouchers from both sides, because HMRC does ask for them.
Documents You Must Have Ready for Double Taxation Relief
Getting the paperwork wrong is the most common reason DTR claims are delayed or rejected. Here is what you need to have in order:
- Tax Residency Certificate from His Majesty’s Revenue and Customs (HMRC)
- Form 10F filed electronically on the Indian Income Tax portal
- PAN card copy
- Passport and visa copies confirming UK residency
- Form 67 filed before your Indian ITR submission
- HMRC's Form DT-Individual for UK-side relief
- Bank statements and tax payment records from both countries
- Any withholding tax certificates from Indian banks or companies
Every document should correspond to the same financial year. Mismatched dates are a common cause of complications.
What Has Changed Recently for UK NRIs
The India-UK relationship on taxation has not been static. In 2025, ongoing trade negotiations between both governments included discussions on broader financial coordination. A Double Contributions Convention is being proposed specifically to address the situation where NRIs end up contributing to both the Indian and UK social security systems simultaneously, which is a separate but related financial burden.
Any changes to the DTAA provisions or new bilateral agreements will affect how NRIs calculate and claim their relief. Reviewing your position at least once a year, especially around the filing season, is good practice.
Conclusion
Double taxation relief exists to solve a real and recurring problem for UK-based NRIs, and the India-UK DTAA does that job reasonably well when used correctly. The treaty covers the income types most NRIs deal with, offers meaningful rate reductions, and provides legal certainty on cross-border tax rights. But the key word is "correctly." Filing the wrong form, missing the TRC, or skipping Form 67 will cost you the benefit entirely. The process is not complicated, but it does demand attention. If your India-UK income situation is at all complex, professional guidance from someone who works specifically in international taxation is worth every penny.
