India-UK DTAA in 2026: How a UK NRI Avoids Paying Tax Twice

Every January, a familiar message lands in our inbox. It usually reads something like this: "My Indian bank has deducted nearly a third of my NRO fixed-deposit interest as tax. I already pay tax in the UK. Am I really being taxed twice on the same money?"

The short answer is: you are being over-taxed at source, and there is a perfectly legitimate way to fix it. The default tax deducted at source on NRO interest is around 30% plus cess — roughly 30.9% at the time of writing, and higher still once your Indian income crosses ₹1 crore — applied under section 195. But the India-UK Double Taxation Avoidance Agreement (DTAA) caps that rate at about 15% on interest. The difference is not small. On a substantial NRO deposit, claiming the treaty rate instead of the default can keep thousands of rupees in your account every year.

The catch — and it is the catch that trips up most UK NRIs — is that the lower rate is not automatic. You have to prove you are entitled to it with two specific documents: a Tax Residency Certificate (TRC) from HMRC, and an online Form 10F. Get those right and the treaty works for you. Get them wrong (or assume they are optional) and the bank quite reasonably deducts the full 30.9%.

This is a general explainer, not tax advice. Treaty relief is genuinely CA territory once the numbers get large. What we do at NriDirect is the unglamorous foundation underneath it: making sure your PAN status and paperwork are correct so your bank can apply the right rate in the first place, and so you can actually claim a refund later if too much was withheld.

Why you are being taxed at nearly 31% by default#

When an Indian bank pays interest into your NRO account, it is legally obliged to deduct tax at source before the money reaches you. For a non-resident, the default rate under section 195 is the headline 30% plus cess — landing around 30.9% in practice, and edging higher with surcharges once total Indian income is large (over ₹1 crore).

That default exists for a sensible reason: the bank has no way of knowing your overseas tax position. So it applies the conservative, full-rate deduction unless and until you hand it the paperwork that proves you qualify for something better. Without that paperwork, there is no treaty rate — just the default.

This is the single most common surprise for first-time NRO account holders. The money is not lost — you can often reclaim the excess by filing an Indian return — but recovering an over-deduction a year later is far more painful than getting the right rate applied up front.

What the India-UK treaty actually caps#

The DTAA between India and the UK is designed precisely so the same income is not fully taxed twice. For UK-resident NRIs, the headline reliefs people most often use are:

• Interest (including NRO interest) — capped at around 15% under the treaty (broadly Article 12).
• Dividends — capped at around 10% under the treaty (broadly Article 11).

Treat those article numbers as approximate; treaty texts are renumbered and reinterpreted over time, and what matters in practice is the rate, the income type, and the paperwork.

A word of honesty on capital gains: there is no clean treaty exemption that wipes them out. Relief on gains generally comes through the Foreign Tax Credit mechanism — you pay where the gain is taxable and claim credit in the other country — rather than a tidy cap like the one on interest. So if your question is about selling Indian property or shares, do not expect the DTAA to make Indian tax disappear; expect it to prevent double tax via credit. Our companion note on selling property in India as an NRI covers the TDS-and-PAN side of that.

Here is the headline that actually motivates most people to do the paperwork.

	Without DTAA	With DTAA
Interest TDS rate	About 30.9%	About 15%
Dividend TDS rate	About 20% or 30.9%	About 10%
Paperwork needed	None	TRC plus online Form 10F
Annual renewal	Not applicable	Yes, each financial year

(Dividend default rates vary with how the company withholds and your surcharge band; the point is simply that the treaty rate is markedly lower than the default, if you claim it correctly.)

The TRC: your proof of UK tax residence#

The first of the two documents is the Tax Residency Certificate. It is the evidence that you are genuinely tax-resident in the UK for the relevant period — which is what entitles you to the India-UK treaty in the first place.

UK residents get a TRC from HMRC, typically as a certificate of residence applied for via the RES1 route. It is a request to HMRC to certify your UK residence to a foreign tax authority. A few practical points we see catch people out:

• A TRC is generally valid for one financial year, so you must renew it annually if you want to keep claiming treaty benefits year after year. A two-year-old certificate will not do.
• The financial year that matters for the Indian side runs 1 April to 31 March, so plan your TRC to cover the period your Indian interest accrues.
• Apply in good time. HMRC processing is not instant, and your bank will keep deducting the full rate until the certificate is in its hands.

Form 10F: mandatory, and mandatory online#

The second document is Form 10F, and this is where the biggest, most expensive misunderstanding lives.

The myth — still repeated on plenty of forums — is: "If your TRC already contains all the required particulars, Form 10F is optional." That was once a defensible reading. It is wrong now. Since 1 October 2023, Form 10F must be filed online on the income-tax e-filing portal, even if the TRC already contains every particular. There is no "my TRC is detailed enough" exemption any more.

So the correct mental model for 2026 is simple: TRC and online Form 10F, every year. A complete TRC alone is not sufficient.

The point almost nobody knows: Form 10F without a PAN#

Here is the genuinely useful, widely-missed fact. You do not need a PAN to file Form 10F.

The portal has a registration category specifically for this: "Non-Residents not holding and not required to have PAN." Register under that category and you can file Form 10F online without ever holding a PAN. For a UK NRI whose only Indian connection is a modest NRO deposit, that can be the whole solution to getting the 15% rate at source.

That said — and this is where we are deliberately honest rather than salesy — a PAN still matters. It makes the bank's job of applying the lower TDS at source far smoother, it is what you need to file an Indian income-tax return, and it is essential to claim a refund if too much was withheld before your paperwork was in place. So the PAN-less route gets you the treaty rate, but a PAN gives you the full toolkit. For most UK NRIs with ongoing Indian income, holding a PAN is the cleaner long-term setup, which is exactly why our NRI PAN card service is so often the first thing we sort. Our NRI PAN card 2026 guide walks through applications and corrections end to end.

How to claim the treaty rate, step by step#

Here is the sequence we walk UK NRIs through. None of it is conceptually hard; the value is in doing it in the right order and on time.

Claiming the DTAA rate on NRO interest

1. Get your HMRC TRC — apply via the RES1 / certificate-of-residence route for the relevant UK tax period, and allow time for HMRC to issue it.
2. File Form 10F online — log in to the income-tax e-filing portal (with a PAN, or under the "not required to have PAN" category) and submit Form 10F for the year.
3. Hand both to your bank — give your TRC and the filed Form 10F (plus any self-declaration of beneficial ownership the bank asks for) to the branch holding your NRO account.
4. Confirm the rate applied — check that subsequent interest is deducted at about 15%, not 30.9%, and keep evidence for your records.
5. Reclaim any excess via a return — if too much was withheld earlier in the year, file an Indian income-tax return (PAN required) to recover the difference.
6. Renew annually — repeat the TRC and Form 10F each financial year, before the new year's interest starts accruing.

If filing an Indian return to reclaim over-deducted tax sounds daunting, our guide on the NRI income-tax return for 2026 explains who needs to file and how the refund route works.

Pensions: a cleaner part of the treaty#

Pensions are one area where the DTAA gives a relatively tidy answer, so it is worth a plain-English summary (with the usual caveat that article numbers are approximate and your facts matter).

• A private or employer pension and annuities are generally taxable only in your country of residence (broadly Article 20). So a UK private pension paid to a UK resident is taxed in the UK only — not also in India.
• A government-of-India service pension is generally taxable only in India (broadly Article 19) — unless you are a UK national, in which case the position can shift.

For most British-Indian retirees, that means UK occupational and personal pensions stay firmly in the UK net, which is usually the simpler and more favourable outcome. But government-service pensions and dual-nationality cases are genuinely fact-specific, so do not self-diagnose a six-figure pension on the strength of a blog paragraph.

Myth-busting the DTAA, quickly#

Because the same wrong ideas cost UK NRIs real money, here are the ones to retire:

• "A complete TRC alone is enough." No. Since the October 2023 online mandate, Form 10F is required as well, even with a fully detailed TRC.
• "Form 10F is optional." No. It is mandatory, and it must be filed online.
• "I can't claim the treaty rate without a PAN." No. Register under the no-PAN category and file Form 10F online. (A PAN still helps for refunds and returns.)
• "The DTAA exempts my Indian capital gains." No. Gains relief is via Foreign Tax Credit, not a clean treaty exemption.
• "My UK pension is taxable in India because I'm Indian-origin." Generally no — a UK private pension is taxed in the UK only under the residence rule.

DIY versus getting help — the honest call#

Plenty of UK NRIs handle the treaty rate themselves, and you can too. The honest breakdown:

• DIY is reasonable for: applying to HMRC for your TRC, filing Form 10F online (with or without a PAN), and handing both to your bank. If your only Indian income is straightforward NRO interest, this is a manageable annual chore.
• Pay a chartered accountant for: anything involving capital gains and Foreign Tax Credit, larger or multi-source income, surcharge bands above ₹1 crore, pension edge-cases, and filing the Indian return that reclaims over-deducted tax. This is regulated tax work and worth every rupee.
• Where we fit: we are not tax advisers and will not pretend to be. What we do is get your PAN right — a fresh PAN, a correction, or fixing an inoperative one — so the bank can apply the lower rate cleanly and so the refund route is open to you. If you are even slightly unsure whether your PAN reflects the right status, that is the highest-leverage thing to sort first.

If your PAN has been flagged inoperative — a surprisingly common problem for NRIs — it can block the very refund you are trying to claim. Sorting the PAN foundation first is almost always the right order of operations.

The NRI who emailed us in January, for the record, was not being taxed twice in any unfair sense — he was simply being deducted at the default 30.9% because he had never filed a Form 10F. We sorted his PAN, he applied for his HMRC TRC, filed Form 10F online, and the next quarter's interest came through at the treaty 15%. The over-deduction from earlier in the year he reclaimed through his return. None of it was exotic. It was just paperwork, done in the right order and on time.

If your only loose end before you claim the treaty rate is whether your PAN is correct and operative, that is exactly the kind of thing we sort quickly and properly — so the rest of the DTAA process actually works the way it is meant to.
