Why Your Indian Mutual Funds Get Taxed Harder in the UK: The Offshore Income Gains Trap on Non-Reporting Funds

You are an Indian who moved to London four or five years ago, you kept your SIPs running in two or three Indian equity funds because the rupee returns looked strong and you did not want to disturb a working portfolio, and you have always assumed that when you eventually sell, you will pay the UK's capital gains tax rate, the same 18% or 24% your British colleagues pay on their investment trusts and ETFs. That single assumption is the most expensive mistake I see UK-resident NRIs make, and it is quiet, because nothing goes wrong until you sell or switch funds. At that point HMRC does not treat your HDFC or SBI equity fund as a normal capital asset. It treats the gain as an Offshore Income Gain, charges it to income tax at up to 45%, and denies you the CGT allowance and the capital losses you were counting on to soften the bill.

The 30-second answer: If you are UK-resident, your Indian mutual funds are almost certainly non-reporting funds, because Indian AMCs essentially never apply for HMRC Reporting Fund Status. When you sell a non-reporting fund at a profit, the gain is an Offshore Income Gain (OIG), charged to income tax at up to 45% (the additional rate for 2026/27), not at the 18% / 24% capital gains tax rates that apply to reporting funds and direct shares. You cannot use the annual CGT exempt amount against an OIG, and you cannot set capital losses against it, because an OIG is income in nature. Since 6 April 2025 UK residents are taxed on the arising basis (the old remittance non-dom basis is abolished), so you are taxed as the gain arises, with credit for Indian tax via the India-UK treaty. The fix is to hold India exposure through UK reporting funds, UK or Ireland-domiciled India ETFs, or direct Indian shares.

This guide is written for the UK side of your life specifically, not the Indian side. If you are an NRI in the US, this does not apply to you in the same way, because the US has its own punitive regime called PFIC, which is a separate analysis entirely. What follows is why HMRC splits offshore funds into reporting and non-reporting, why your Indian funds land on the wrong side of that line, exactly how the Offshore Income Gain charge works and why the missing CGT allowance and the blocked losses make it so much harsher than the headline rate suggests, a full worked example on a Rs 20,00,000 gain comparing 45% OIG against 24% CGT with the Indian TDS and UK foreign tax credit interaction, the edge cases including the new-arrivals FIG window and ISAs, and the honest read on what to hold instead.

Why "I will just pay UK capital gains tax" is wrong for an Indian fund

Start with the sentence that causes the damage, because almost every UK-based reader has said some version of it: "When I sell, I pay capital gains tax like everyone else, and I have my annual CGT allowance and my losses to offset it." Every clause assumes your Indian fund sits inside the ordinary CGT system. It does not.

The UK splits offshore funds, meaning collective investment vehicles based outside the UK, into two categories that are taxed completely differently. The dividing line is whether the fund has UK Reporting Fund Status (RFS), an HMRC designation the fund itself has to apply for and maintain.

• A reporting fund has applied to HMRC, agreed to report its income to HMRC each year (including any excess reportable income you must declare even if it was not distributed), and appears on HMRC's published approved list of reporting funds. When you sell a reporting fund, your gain is an ordinary capital gain, taxed under the CGT system at 18% or 24% in 2026/27 depending on your band, with the annual CGT exempt amount and your capital losses both available.
• A non-reporting fund has not done this. When you sell a non-reporting fund at a profit, the gain is not a capital gain at all. It is reclassified as an Offshore Income Gain and charged to income tax at your marginal rate, up to 45%, with no CGT allowance and no capital loss offset.

That reclassification is the whole story. The same disposal, the same profit, can be taxed at 24% or at 45% depending on a single administrative fact about the fund: whether it joined HMRC's reporting regime. The rules sit in the offshore funds legislation and are explained in HMRC's helpsheet HS265.

The policy reason is identical in spirit to why the US has PFIC rules. HMRC does not want a UK resident rolling up income inside an offshore fund year after year, paying nothing, and then claiming the gentler capital gains rate when they finally cash out. The reporting regime is the deal: report your income annually and you get CGT treatment on the gain; refuse to report and the whole gain is treated as the rolled-up income it effectively is, taxed as income. Your Indian fund refused to report, not because of anything you did, but because it never had a commercial reason to join a UK regime. You inherit the consequence.

Why your Indian mutual funds are non-reporting funds

Hold an Indian mutual fund up against the reporting-fund test and the answer is immediate. To be a reporting fund, the fund must apply to HMRC, commit to reporting its income to HMRC every year in the form HMRC requires, and stay on the published list. Indian asset management companies essentially never do any of this.

The reasons are structural, not accidental:

• Almost none of an Indian AMC's investors are UK-resident, so there is no commercial pressure to take on a foreign reporting obligation for a tiny slice of the book.
• The data HMRC wants, your share of the fund's income computed on UK principles, does not fall naturally out of Indian fund accounting, which is built for Indian tax and SEBI rules.
• Applying for and maintaining RFS is an ongoing annual cost the AMC has no reason to bear.

So the practical position is blunt. Your HDFC, SBI, ICICI Prudential, Nippon India, Axis, Kotak or any other Indian-domiciled mutual fund is a non-reporting fund for UK purposes. That includes equity funds, debt funds, liquid funds, hybrid funds, ELSS tax-saving funds, and Indian-domiciled index funds and ETFs. Being a passive index tracker does not help; what matters is the fund's reporting status, not its investment strategy. If it is an Indian-domiciled pooled fund, assume it is non-reporting unless you have checked the HMRC list and found it, which you will not.

There is a simple check you can do. HMRC publishes the approved list of reporting funds and updates it regularly. If your fund is not on it, and an Indian retail fund will not be, then any gain you make on selling it is an Offshore Income Gain. Always confirm against the list rather than assume, but the answer for Indian retail funds is reliably the same.

What is not caught, and this is the seed of the fix. Direct Indian shares in your own demat account, Reliance or Infosys held individually, are not offshore funds at all; they are ordinary shares, and your gain on them is a normal capital gain under the CGT system. A UK-domiciled or Ireland-domiciled India ETF or fund, or any offshore fund that does hold RFS, gives you CGT treatment too. Keep both facts in mind; they are where the closing read goes.

How the Offshore Income Gain charge actually works

When you dispose of a non-reporting fund, the gain is computed much as a capital gain would be, proceeds minus cost, but then the character of that gain changes. Instead of being a chargeable gain inside the CGT system, it becomes an Offshore Income Gain and is charged to income tax for the tax year of disposal.

That single change of character has four consequences, and the four together are what make the OIG so much worse than the 45% headline rate suggests on its own.

1. The rate is your income tax marginal rate, not the CGT rate. For 2026/27 that is 20% basic, 40% higher, or 45% additional, depending on your band. Compare that to 18% / 24% CGT on a reporting fund. An additional-rate taxpayer pays 45% versus 24%, almost double.
2. The gain stacks on top of your other income. Because the OIG is income, it sits on top of your salary, rental income and other income for the year. A large gain can push part of your income into a higher band, or strip your personal allowance (which tapers away above GBP 100,000 of income), so the marginal cost can exceed even the headline 45% in a narrow income range.
3. The annual CGT exempt amount cannot be used against it. Your CGT allowance shelters capital gains. An OIG is income, so the allowance simply does not apply. You lose a shelter you would have had on a reporting fund.
4. Capital losses cannot be set against it. This is the asymmetry that catches people hardest. If you have capital losses, from UK shares, from a reporting fund, from property, anywhere, they are capital in nature and an OIG is income in nature, so they do not net. Even a loss on another Indian non-reporting fund does not help, because a loss on a non-reporting fund is treated as a capital loss, not an income loss, so it cannot reduce the OIG income charge on a different fund. You are taxed on every gain as income, with your losses stranded on the capital side where they cannot reach.

Put those four together and the picture is stark. A reporting-fund investor pays 18% or 24%, uses their annual exemption, and nets their losses. A non-reporting-fund investor pays up to 45%, uses no exemption, and cannot touch their losses. The same India exposure, taxed in two entirely different worlds, and the Indian fund puts you in the worse one by default.

Arising basis since 6 April 2025: there is no more hiding it offshore

There used to be an escape hatch for some NRIs in the UK: the remittance basis under the old non-domiciled regime. If you were non-dom and claimed it, foreign income and gains that you kept offshore and did not bring into the UK were largely outside UK tax. An NRI could, in principle, sell an Indian fund, keep the proceeds in India, and avoid the UK charge as long as the money never came to Britain.

That hatch is closed. From 6 April 2025 the remittance basis and the old non-dom regime are abolished. UK residents are now taxed on the arising basis, meaning you are taxed on your worldwide income and gains as they arise, regardless of whether you bring the money to the UK. So the Offshore Income Gain on your Indian fund is now taxed in the UK tax year you sell, full stop, whether or not a single pound of the proceeds ever leaves India.

This matters enormously for the reader who has been comfortable for years. The strategy of "sell in India, keep it in India, stay quiet in the UK" no longer works for a UK resident on the arising basis. The gain arises, it is an OIG, and it goes on your UK Self Assessment return for that year. The abolition removed exactly the planning that used to make Indian funds tolerable for some UK-resident Indians, which is why this guide is suddenly far more urgent than it would have been two years ago. For where your UK and Indian residency lines fall, see NRI residency and RNOR rules.

The one significant exception is the new four-year FIG window for recent arrivals, covered in the edge cases below. If you do not qualify for that, you are on the arising basis and the OIG is taxed now.

The Indian side: TDS and the foreign tax credit

You do not pay UK tax in a vacuum, because India taxes the same sale too, and the two systems interact through the India-UK Double Taxation Avoidance Agreement.

On the Indian side, when an NRI sells an Indian mutual fund, the AMC deducts tax at source (TDS) on the gain before paying you. For equity-oriented funds the long-term capital gains rate in India is 12.5% above the annual exemption and short-term is 20%; for non-equity funds the treatment differs and gains are typically taxed at slab or applicable rates. The exact Indian figure depends on the fund type and holding period, and is set out in capital gains tax on NRI shares and mutual funds. The key point for the UK analysis is that you will have paid some Indian tax on the same gain, usually collected as TDS.

The UK then gives you credit for that Indian tax against your UK liability on the same gain, under the treaty and the UK's foreign tax credit rules. But the credit has a hard ceiling: it is the lower of the Indian tax paid and the UK tax due on that gain. So if your UK OIG charge is 45% and you paid, say, 12.5% in India, the Indian tax wipes out part of the UK bill but you still pay the difference up to the UK rate. The credit stops you being taxed twice on the same money; it does not bring your total cost below the higher of the two countries' rates, which here is the UK's. To claim it on the Indian side you use the treaty machinery; on the UK side it is claimed through Self Assessment. For the mechanics, see foreign tax credit and Form 67, the India-UK DTAA deep dive, and DTAA relief for NRIs.

The honest framing here: the foreign tax credit is real and worth claiming, but it does not rescue you from the OIG problem. It simply means the UK collects the gap between the low Indian rate and the high UK income tax rate. The damage is that the UK rate is income tax up to 45% rather than CGT at 24%, and the credit does nothing to change which rate applies.

A worked example: Rs 20,00,000 gain, OIG at 45% versus CGT at 24%

Numbers make this concrete. Take a real, ordinary case.

Anil moved to Manchester in 2018 and is now a UK tax resident and an additional-rate taxpayer (his UK income is comfortably above the GBP 125,140 threshold where the 45% rate begins). He has held an Indian large-cap equity mutual fund for several years. In the 2026/27 UK tax year he sells the entire holding and realises a gain of Rs 20,00,000.

To keep the arithmetic clean, assume an exchange rate of Rs 100 to GBP 1, so the gain is GBP 20,000. (Use whatever rate applies on your actual disposal date; the proportions do not change.)

Step 1: the Indian tax (TDS)

His fund is equity-oriented and held long term, so India taxes the long-term gain at 12.5% above the small annual exemption. Ignoring the exemption for simplicity, the Indian tax is:

• Rs 20,00,000 times 12.5% = Rs 2,50,000, which is GBP 2,500.

This is deducted as TDS by the AMC before he receives the proceeds.

Step 2: the UK charge if the fund were a reporting fund (the 24% world)

Suppose, in a parallel universe, the fund had UK Reporting Fund Status. Then the GBP 20,000 gain is a capital gain, taxed under CGT. As a higher/additional-rate investor his CGT rate on the fund gain is 24% for 2026/27, and he could also use his annual CGT exempt amount and any capital losses. Ignoring those shelters for a like-for-like rate comparison:

• GBP 20,000 times 24% = GBP 4,800 UK CGT.
• Less foreign tax credit for the GBP 2,500 Indian tax (capped at the lower of Indian tax and UK tax, here GBP 2,500).
• Net additional UK tax: GBP 4,800 minus GBP 2,500 = GBP 2,300.
• Total tax across both countries: GBP 4,800 (GBP 2,500 to India plus GBP 2,300 to the UK).

In the reporting-fund world, his all-in cost is GBP 4,800, and that is before he uses his CGT allowance and losses, which would push it lower.

Step 3: the UK charge as it actually is, a non-reporting fund (the 45% world)

In reality the Indian fund is non-reporting, so the GBP 20,000 gain is an Offshore Income Gain, charged to income tax at 45%:

• GBP 20,000 times 45% = GBP 9,000 UK income tax.
• He cannot use his CGT annual exempt amount against it (it is income, not a capital gain).
• He cannot set any capital losses against it (capital losses do not reduce income).
• Less foreign tax credit for the GBP 2,500 Indian tax, capped at the lower of Indian tax and UK tax. Here Indian tax (GBP 2,500) is lower than the UK charge (GBP 9,000), so the full GBP 2,500 is creditable.
• Net additional UK tax: GBP 9,000 minus GBP 2,500 = GBP 6,500.
• Total tax across both countries: GBP 9,000 (GBP 2,500 to India plus GBP 6,500 to the UK).

The comparison, stated plainly

• Reporting fund (24% CGT): total tax about GBP 4,800, before allowance and losses, which would reduce it further.
• Non-reporting Indian fund (45% OIG): total tax GBP 9,000, with no allowance and no losses available.

The difference is GBP 4,200 on a GBP 20,000 gain, and that gap is purely the cost of the fund being non-reporting. The UK takes GBP 6,500 instead of GBP 2,300, almost three times as much UK tax, on identical economics. And the example understates the gap, because in the reporting-fund world Anil could have used his annual CGT exempt amount and any capital losses to cut the GBP 4,800 down, shelters that are entirely unavailable against the OIG. The honest read: the Indian fund is simply a poor UK tax wrapper. The foreign tax credit stops double taxation but does nothing about the fact that you are taxed at income rates rather than capital rates, and stripped of the CGT shelters on top.

Edge cases

The general rule, that almost every Indian mutual fund is a non-reporting fund whose gain is an OIG taxed as income, holds widely, but several situations deserve their own note.

Reporting versus non-reporting, and how to actually check. Not every offshore fund is non-reporting; UCITS funds, many Ireland and Luxembourg-domiciled ETFs, and some institutional funds do hold RFS. The point is not that all foreign funds are bad, it is that Indian retail mutual funds specifically are not on the list. Before assuming, check the fund against HMRC's published reporting funds list. If a specific share class of a fund you hold is on the list, that class gets CGT treatment; if it is not, it is non-reporting. Share class matters, because a fund can have reporting and non-reporting classes, so check the exact one you own.

The new-arrivals FIG window. If you have recently become UK-resident after at least ten years of non-residence, you may qualify for the four-year Foreign Income and Gains (FIG) regime introduced from 6 April 2025. For your first four years of UK residence you can elect to have qualifying foreign income and gains, which can include gains on your Indian funds, exempt from UK tax, even if you bring the money to the UK. This is the one genuine shelter left after the abolition of the remittance basis, and it makes the first four years the right window to rationalise your Indian fund holdings while the OIG charge is switched off for you. After the four years end you are on the arising basis and the OIG bites in full. The details, including who qualifies and how the election works, are in the UK NRI FIG regime and the four-year window. Plan disposals into the FIG window if you have one.

ISAs do not shelter a non-reporting fund, and you usually cannot hold one anyway. A UK Individual Savings Account (ISA) shelters investments from UK income tax and CGT, which would in theory neutralise the OIG problem. But two things bite. First, you generally cannot hold an Indian mutual fund inside a UK ISA at all, because ISAs are restricted to qualifying investments, broadly UK-recognised funds and shares, not Indian-domiciled retail funds. Second, an ISA is the right home for UK reporting funds or UK-listed India ETFs, which is exactly the fix this guide points you toward. So the ISA does not rescue your existing Indian fund; it is a reason to hold your India exposure through a reporting fund or a UK-listed ETF inside the ISA instead. See ISAs and pensions for the non-resident and returning NRI.

Excess reportable income on reporting funds. If you do move to reporting funds, be aware of the flip side: a reporting fund can have excess reportable income, income the fund earned but did not distribute, which you must still declare and pay income tax on each year even though you did not receive cash. It is a smaller annual admin point, not a reason to avoid reporting funds, but it is worth knowing so the move does not surprise you later.

Switching funds is a disposal. Switching from one Indian fund to another, or moving from a regular to a direct plan, is a disposal for UK tax even though no money reaches your bank. Each switch crystallises an OIG on the fund you left. People who "rebalance" their Indian portfolio every year without selling to cash are often triggering OIGs annually without realising it.

Temporary non-residence. If you leave the UK and return within roughly five years, anti-avoidance rules on temporary non-residence can pull gains you realised while away back into UK charge on your return. Selling your Indian funds during a short spell abroad to dodge the OIG often does not work. See the UK NRI temporary non-residence CGT rules.

The closing read

Here is the honest read, scoped to who you are.

If you are UK-resident and on the arising basis, which since 6 April 2025 means almost everyone who is not in their first four years here, then you should not be holding Indian mutual funds for UK purposes, in my view, unless you have a specific reason and an adviser who has priced the Offshore Income Gain cost for you. The OIG charge taxes your entire gain as income at up to 45% rather than as a capital gain at 24%, it denies you the annual CGT exempt amount, and it strands your capital losses where they cannot reach the charge. The foreign tax credit for Indian tax stops you being taxed twice, but it does nothing to change the rate or restore the shelters. On a Rs 20,00,000 gain that is roughly GBP 6,500 of UK tax instead of GBP 2,300, on identical economics. No rupee return reliably overcomes that gap year after year.

The fix is not complicated, it is just different from what your relatives in India do. To get Indian or India-themed exposure without the OIG regime, hold one of three things. UK reporting funds, meaning offshore funds that appear on HMRC's approved list, so your gain is a capital gain at 18% or 24% with the allowance and losses available. UK-listed or Ireland-domiciled India ETFs, which give you Indian market exposure inside the CGT system and can sit inside an ISA or pension. Or direct Indian shares in your own demat account through the Portfolio Investment Scheme, because individual operating-company shares are not offshore funds at all and their gains are ordinary capital gains. The trade-offs of each are in NRI investing in index funds and ETFs, tax-efficient investing for NRIs, and buying Indian stocks through PIS, and how it fits a whole portfolio is in NRI portfolio and asset allocation.

If you already hold Indian funds and only now realise the exposure, do not panic-sell blindly. If you are still inside your four-year FIG window, that is the time to rationalise, because the OIG is switched off for you during those years. If you are on the arising basis, model the OIG cost of selling now against the cost of continuing to hold, get the gains correctly reported on your Self Assessment, and claim the foreign tax credit for the Indian tax. This is one of the few areas where paying a cross-border tax adviser pays for itself, because the interaction of Indian TDS, the treaty credit, and the UK income tax bands genuinely is too involved to eyeball.
