Returning to India from the UK - The playbook to tax-free capital gains
- 2 days ago
- 12 min read
Relocating from the UK to India comes with a mountain of admin, from sorting out your P45 to packing up your flat. But before you get entirely lost in the logistics, make sure you don't overlook a crucial financial strategy that could shield your wealth from hefty taxes down the line.
If your move is timed correctly, there is a window during which neither the UK nor India will tax the gains on your investment portfolio. Used well, that window lets you “reset” the cost base of your shares to today’s market value, so that years of accumulated growth are never taxed. This guide explains how the strategy works, the recent UK tax changes that affect it, and the conditions you must satisfy for it to hold up.
In one sentence When you are a UK non-resident and an Indian RNOR at the same time, you can sell appreciated shares free of capital gains tax in both countries, repurchase them immediately, and lock in a higher cost base for the future. |

The "Zero Tax" window
The single biggest tax-saving opportunity for a returning NRI is the overlap between two residency statuses: your UK non-resident status and your Indian RNOR (Resident but Not Ordinarily Resident) status. India:
When you return to India you do not immediately become a fully taxable resident. For a transitional period (usually two to three financial years). The defining feature of RNOR status is that India does not tax your foreign income, and this includes capital gains on the sale of foreign shares such as UK listed or US listed stocks. UK:
At the same time, having left the UK, you become a UK non resident. A non-resident is, broadly, outside the scope of UK capital gains tax on the disposal of shares and securities (UK CGT for non-residents is largely confined to UK land and property).
The Plan:
Put those two facts together and you have a genuine gap: neither country has the right to tax the capital gains on your portfolio. That gap is the planning opportunity.
You need to exploit the overlap between your UK Non-Resident status and your Indian RNOR (Resident but Not Ordinarily Resident) status since this is the single biggest tax saving opportunity for returning NRIs.
Residential status in India
Taxability of income in India depends upon the residential status of an individual which is categorized as:
Resident and Ordinarily Resident (ROR)
Resident Not Ordinary Resident (RNOR)
Non-Resident (NR)
Residential status is important since it determines the taxability of your income
Residential status in India applies to a financial year from 1 April to 31 March.
Correction to a common simplification RNOR is not simply “two years, sometimes three.” It is the result of the day count tests above, applied year by year. An early in the year return can give you three RNOR years. A late return can mean your first full RNOR year does not start until the next financial year. Always map your dates. |
Residential status in the UK
Your UK position is governed by the Statutory Residence Test (SRT). The UK tax year runs 6 April to 5 April.
In the year you leave the UK you would normally still meet the residence conditions for part of the year, so the SRT provides Split-Year Treatment.
HMRC essentially draws a line in the sand on the day you leave. For the first part of the year (while you lived in the UK), you are taxed as a UK resident. For the second part (after you move to India), you are treated as a non-resident. Once in the non-resident part of the year, you will no longer pay UK tax on your foreign income.
How the strategy works
When you reach the point where you are an RNOR in India and a non-resident in the UK at the same time, you have a window in which a disposal of shares is taxed by neither country. The play has two steps:
Sell your appreciated shares during the window. Because you are outside CGT in both jurisdictions, you pay zero capital gains tax on all the profit accumulated to date.
Repurchase the same shares immediately. This re-establishes your holding at its current market value, so your cost base for any future sale is reset upward.
The benefit lands later. Once you become an ROR, India taxes your worldwide gains but only the growth above your cost base. By resetting that base to today’s value, every pound or dollar of growth earned during your years abroad is permanently removed from the future Indian tax calculation.
This works for UK-listed shares and equally for US-listed stocks, ETFs and vested RSUs. A returning NRI who built a US portfolio can run exactly the same reset.
Two practical points on the repurchase • There is no UK “bed-and-breakfasting” obstacle, because as a non-resident the UK 30 day share matching rule is irrelevant to you. India has no equivalent rule for ordinary foreign shareholdings. An immediate same day repurchase is fine. • The repurchase restarts your holding period. India’s long term vs short term capital gains classification runs from the new purchase date. So a sale soon after you become ROR could be taxed as a short term gain. |
Example 1: Resetting UK Shares
Priya is an Indian citizen who lived and worked in the UK for nine years. She moves back to India permanently on 1 June 2026. She holds 2,000 shares in a UK listed fund, bought in March 2016.
Step 1 — Map the residency timeline
Period | UK status | India status |
6 Apr – 31 May 2026 | Resident (UK part of split year 2026/27) | Non-Resident |
1 Jun 2026 – 31 Mar 2027 | Non-resident (overseas part of split year) | Resident – RNOR |
FY 2027–28 and FY 2028–29 | Non-resident | Resident – RNOR |
FY 2029–30 onward | Non-resident | Resident – ROR |
The overlapping zero-tax window runs from 1 June 2026 to 31 March 2029 — the period in which Priya is simultaneously a UK non resident and an Indian RNOR. Any share disposal in that window is taxed by neither country.
Step 2 — Sell and repurchase inside the window
In September 2026, comfortably inside the window, Priya sells and immediately rebuys her holding.
Item | Amount |
Original purchase (March 2016): 2,000 shares @ £25.00 | £50,000 (old cost base) |
Market value at sale (Sept 2026): 2,000 shares @ £92.00 | £184,000 |
Unrealised gain crystallised | £134,000 |
UK capital gains tax due | £0 (non-resident — outside UK CGT on shares) |
Indian tax due | £0 (RNOR — foreign gain, proceeds kept in UK account) |
Repurchase same day: 2,000 shares @ £92.00 | £184,000 (new cost base) |
Step 3 — The payoff years later
Priya is now an ROR. In 2033 she sells the holding at £120.00 per share (£240,000). India taxes the gain over her cost base:
Scenario | Indian taxable gain in 2033 | Sheltered |
Without the reset (cost base £50,000) | £240,000 − £50,000 = £190,000 | |
With the reset (cost base £184,000) | £240,000 − £184,000 = £56,000 | £134,000 of gain permanently removed from Indian tax |
Example 2: Resetting US Shares
Arjun returns to India from the UK on 20 April 2026. He holds 600 shares in a Facebook/ Meta (a US technology company acquired in 2020. Because he arrives early in the financial year, he is RNOR for FY 2026–27, and his RNOR status runs through FY 2028–29.
Item | Amount |
Original cost (2020): 600 shares @ $60.00 | $36,000 (old cost base) |
Market value at sale (Aug 2026): 600 shares @ $310.00 | $186,000 |
Unrealised gain crystallised | $150,000 |
US tax due | $0 (non-resident alien — no US CGT on stock) |
Indian tax due | $0 (RNOR — proceeds settled to US brokerage account) |
Repurchase same day: 600 shares @ $310.00 | $186,000 (new cost base) |
When Arjun, now an ROR, sells in 2032 at $360.00 per share ($216,000):
Scenario | Indian taxable gain in 2032 | Sheltered |
Without the reset (cost base $36,000) | $216,000 − $36,000 = $180,000 | |
With the reset (cost base $186,000) | $216,000 − $186,000 = $30,000 | $150,000 of gain permanently removed from Indian tax |
Example 3: How Mistiming Costs You
Meera returns to India and holds a portfolio with an unrealised gain of £100,000. The reset only delivers its zero tax result if she sells inside the window and keeps the proceeds outside India. The table shows the same sale under three different choices.
What Meera does | Result | Indian tax on the £100,000 gain |
Sells during her RNOR window. Proceeds settle into her UK brokerage account | Correct — foreign gain, not received in India | £0 |
Waits until FY 2029–30, after RNOR has ended and she is an ROR | Trap — an ROR is taxed on worldwide gains | Full gain taxable |
The lesson: the window is defined by both timing and the destination of your money. Selling at the right moment but routing the cash to an Indian account undoes the entire benefit.
Things You Must Get Right
Confirm you have genuinely shed the other country’s tax residency. The window only exists if neither country can tax you. This means valid UK split year treatment under the SRT, and for US assets, non resident alien status. If either leg fails, so does the strategy.
Mind the UK temporary non-residence rule. If you were UK-resident in 4 of the 7 tax years before leaving and you return to the UK within five complete tax years, gains you realised while non resident can be taxed in your year of return. The strategy assumes a genuine, long-term move.
Track your RNOR expiry precisely. RNOR usually lasts two financial years and sometimes three, depending on your arrival date and travel history. Once you become an ROR, India taxes your worldwide income and gains. Calculate your RNOR period and act inside it.
Plan the inheritance tax tail alongside the reset. Under the post-April2025 UK rules, your worldwide estate (including Indian assets) can remain within UK inheritance tax for 3 to 10 years after you leave. The cost base reset does nothing for inheritance tax. That exposure needs its own plan.
Also worth factoring in • Transaction costs and spread. Selling and rebuying incurs brokerage and a bid/offer spread. On liquid stocks this is small against the tax saved, but it is not zero. • Foreign asset reporting. An RNOR is not required to disclose foreign assets in Schedule FA of the Indian return, but an ROR is. Keep clean records of your reset cost base for when that obligation begins.

The New UK Tax Rules: The End of “Non-Dom” Status
The UK overhauled the taxation of internationally mobile individuals from 6 April 2025. The reform ended the “non-dom” regime that let UK residents with roots abroad keep their overseas income outside UK tax.
If you are an Indian-origin individual living in the UK, these changes affect both what you pay while you remain and the financial case for returning to India.
What “non-dom” status used to mean. An individual who lived in the UK but whose permanent home was elsewhere (for many readers of this guide, India) could elect for the “remittance basis” of taxation. Under it, foreign income and gains were kept out of the UK tax net entirely, as long as the money was not brought into, or “remitted” to, the UK. An Indian domiciled professional in London could hold Indian rental income, dividends from Indian companies, business profits and capital gains on Indian assets free of UK tax simply by leaving the money in India.
Domicile and the remittance basis are gone. Both the concept of domicile for tax purposes and the remittance basis it underpinned were abolished on 6 April 2025 and replaced with a system based purely on residence. This is the single most important change for Indian-origin individuals living in the UK.
The 4-year FIG regime. New arrivers who have been non-UK resident for the previous 10 tax years can claim the Foreign Income and Gains (FIG) regime for their first four years of UK residence, paying no UK tax on foreign income and gains in that period. After those four years (and for everyone already past them) worldwide taxation applies in full.
Your Indian income is now within UK tax.
This is the heart of the matter. Once you are UK resident and beyond any FIG window, the UK taxes your worldwide income and gains (including income arising in India).
Indian rental income, dividends from Indian companies, interest, business profits and capital gains on Indian assets all become reportable and taxable in the UK (whether or not you ever bring the money to Britain).
The India–UK Double Taxation Avoidance Agreement gives credit for tax already paid in India, so the same income is not taxed twice over. However, where the UK rate is higher than the Indian rate, you pay the difference to HMRC. The work of reporting Indian income to two tax authorities falls to you either way.
Inheritance tax is now residence-based — and this one affects you directly.
UK inheritance tax (IHT) no longer follows domicile.
It now follows a “long-term resident” (LTR) test: if you have been UK-resident for at least 10 of the previous 20 tax years, your worldwide estate — including your Indian assets — is within the scope of UK IHT.
The IHT “tail”. Crucially, LTR status does not end the day you leave the UK. It continues for a tail period of between 3 and 10 years after departure, depending on how long you were UK-resident. A short tail of 3 years applies if you were resident for 10 to 13 of the last 20 years; the tail lengthens towards 10 years for longer residence. During the tail, your worldwide estate (Indian property, Indian investments, everything) remains exposed to UK IHT at up to 40%.
Why this matters for your move The income tax and capital gains window discussed in this guide may last only two or three years. The UK inheritance tax tail can last as long as ten. Resetting your cost base solves the CGT problem. It does not solve the IHT exposure. The two need to be planned together. |
Why the New Rules Strengthen the Case for Returning to India
For an Indian origin non-dom, abolishing the remittance basis quietly rewrote the arithmetic of where to live. While the remittance basis applied, being UK-resident cost you nothing in UK tax on your Indian wealth, provided you kept it in India. From 6 April 2025 it can cost a great deal. For many families this has turned the question of returning to India from a purely personal one into a financial decision as well.
The mechanism is simple — UK tax on your Indian income depends on UK residence. If you cease to be UK-resident, by moving to India and meeting the SRT conditions described earlier, your Indian income falls out of the UK tax net entirely. India will tax your Indian source income, as it always would for any resident, but you remove the UK layer completely.
RNOR adds a second layer of relief. On arrival you are an RNOR for two or three years, so India does not tax your genuinely foreign income either. A returning non-dom can therefore land in a position where India taxes only Indian source income, the UK taxes nothing, and any third country income is sheltered until you become an ROR.
The table below shows the structural shift in who taxes what.
Type of income | UK resident non-dom (from 6 Apr 2025) | After returning to India (UK non-resident, RNOR) |
Indian source income — rent, Indian dividends, interest, business profits | Taxable in the UK on a worldwide basis (credit given for Indian tax under the treaty) | Taxed in India only — fully outside the UK net |
Capital gains on Indian assets | Taxable in the UK | Taxed in India only — outside the UK net |
UK-source income — e.g. a UK rental property | Taxable in the UK | Remains UK taxable as UK source. Not taxed in India while you are RNOR |
Third country foreign income — e.g. overseas dividends | Taxable in the UK on a worldwide basis | Not taxed in India while RNOR & outside the UK net |
Before you act on this If you arrived in the UK only recently, the 4-year FIG regime may still shelter your foreign income. There is less urgency to move.
The pressure falls hardest on longer term residents who have used up FIG and now face full worldwide UK taxation.
The temporary non residence rule and the inheritance tax tail described earlier still apply. Leaving the UK solves the income tax problem far faster than it solves the inheritance tax one. Tax is only one input. A move of this size should weigh family, career, currency and lifestyle alongside the numbers. |
