Last month, a Manchester-based software engineer contacted us with a question we hear weekly: "I've maxed out my ISA, I'm contributing to my workplace pension, but I also want to invest in India. How much should I put where?"
She's not alone. At Belong, we work with hundreds of UK-based Indians earning in pounds, planning futures that might span two countries, and worried about making the wrong choice. Over the past year, dozens of UK NRIs have joined our WhatsApp community specifically to discuss cross-border investment strategies.
This guide answers the question comprehensively: how do you balance UK tax-efficient accounts (ISA, pension) with India's growth story? We'll cover allocation strategies, tax implications under UK-India DTAA, what happens when you move back to India, and practical steps to build a truly global portfolio.
Why UK NRIs Face a Unique Investment Dilemma
Unlike UAE-based NRIs who often remit most savings to India, UK NRIs operate in a sophisticated financial system with attractive tax wrappers.
Your UK options offer real benefits:
- ISAs shelter up to £20,000 annually from UK tax
- Workplace pensions get employer matching and tax relief
- NHS pensions provide guaranteed retirement income
- State pensions accumulate with National Insurance contributions
But India offers growth and connection:
- Faster GDP growth (6-7% annually vs UK's 1-2%)
- Rupee assets for family support and eventual repatriation
- Emotional connection to home
- Property and real estate opportunities
The challenge? You can't optimize for just one country when your life spans both.
👉 Tip: Before making any allocation decisions, determine your likely retirement location. The answer fundamentally changes your strategy.
Understanding Your UK Investment Toolkit
ISAs: Your Tax-Free Savings Wrapper
An Individual Savings Account lets UK residents save or invest up to £20,000 per year without paying tax on interest, dividends, or capital gains, according to GOV.UK.
Types include:
- Cash ISA: Savings account with tax-free interest
- Stocks & Shares ISA: Invest in funds, stocks, bonds
- Lifetime ISA: For first home or retirement (under 40 only)
- Innovative Finance ISA: Peer-to-peer lending
What happens when you become non-resident?
GOV.UK guidance states that once you leave the UK and become non-resident for tax purposes, you:
- Cannot contribute new funds to your ISA
- Can keep it open and let investments grow
- Still receive UK tax-free treatment on gains and income
- Must inform your ISA provider of your change in address
The critical issue: while your ISA remains tax-free in the UK, India doesn't recognize this special status.
According to CA Abhinav Gulechha's analysis, once you become an Indian tax resident (Resident and Ordinarily Resident), your ISA income is fully taxable in India as "foreign income." The UK-India DTAA doesn't exempt ISA from Indian taxation.
What this means:
- Keep your ISA if planning to return to UK
- If moving to India permanently, evaluate whether to liquidate or maintain it
- ISA becomes subject to Indian income tax on interest/dividends after you return
- Capital gains may also be taxed when realized
- UK inheritance tax (over £325,000) applies if you die as UK domicile
UK Workplace Pensions and NHS Pensions
Workplace pensions in the UK benefit from:
- Employer contributions (minimum 3% of qualifying earnings)
- Tax relief on your contributions (20-45% depending on income bracket)
- National Insurance savings through salary sacrifice
For NHS staff, the NHS Pension Scheme is one of the best defined benefit schemes available. According to Wesleyan Financial Services, your NHS pension continues even if you move abroad. You can claim it at retirement age regardless of where you live.
Contribution limits after leaving UK:
Royal London guidance confirms that you can contribute to existing UK pensions for five years after leaving:
- Year of departure: 100% of UK earnings
- Following five years: £3,600 gross annually (with tax relief)
- After five years: No tax relief on contributions
Taxation when abroad:
MoneyHelper explains that as a non-UK resident:
- UK State Pension: Usually no UK tax, but may be taxed where you live
- Private/workplace pensions: May pay UK Income Tax and tax in residence country
- 25% tax-free lump sum: Tax-free in UK, but check local rules
- UK-India DTAA generally allows pension taxation in residence country
You can apply for an NT (No Tax) code from HMRC to prevent UK tax deductions if covered by DTAA.
UK State Pension
You need 10 qualifying years of National Insurance contributions to receive any UK State Pension, according to GOV.UK.
Key points:
- Full state pension requires 35 qualifying years
- You can combine UK and EEA/Swiss contributions to meet minimum
- State pension increases annually if you live in UK, EEA, or certain countries
- It does NOT increase if you live in India (frozen at the rate when you leave/claim)
- You can make voluntary NI contributions from abroad to maintain eligibility
Many UK NRIs voluntarily pay Class 2 or Class 3 National Insurance (£923 annually for Class 3 in 2025/26) to protect their state pension entitlement. (Source)
👉 Tip: Check your State Pension forecast at gov.uk/check-state-pension before deciding on voluntary contributions. For some, the payback period makes it worthwhile.
India Investment Options for UK NRIs
Now let's look at what India offers.
National Pension System (NPS)
The NPS is a voluntary, government-regulated retirement scheme managed by PFRDA. UK NRIs aged 18-60 can invest through NRE or NRO accounts.
According to HDFC Life, key features include:
- Minimum annual contribution: ₹1,000 (can contribute in multiples of ₹500)
- Asset allocation: Choose between equity, corporate bonds, government securities
- Portability: Account remains active regardless of where you live
- Withdrawal: At age 60, withdraw 60% tax-free; remaining 40% goes to annuity
- Tax benefits: Deduction up to ₹1.5 lakh under Section 80CCD(1), plus additional ₹50,000 under 80CCD(1B)
NPS has delivered 8-12% returns historically depending on asset allocation, with recent 5-year averages around 9% for top funds as of 2025. (Source)
Pros:
- Low-cost (fund management charges around 0.09%)
- Transparent, government-regulated
- Good for retirement corpus building
- Tax-efficient in India
Cons:
- Lock-in till 60 (with limited partial withdrawals)
- 40% must go to annuity (which often gives lower returns)
- Not flexible for early goals
Mutual Funds
UK NRIs can invest in Indian mutual funds through NRE/NRO accounts, according to HDFC Bank.
You need:
- PAN card
- KYC completion (In-Person Verification can be done at Indian consulate or through registered intermediaries)
- NRE or NRO bank account
- Demat account (not required for mutual funds, but useful for stocks)
- Short-term capital gains (STCG) on equity funds: 20% in India
- Long-term capital gains (LTCG) on equity funds: 12.5% above ₹1.25 lakh
- If UK tax rate is higher (say 25%), you pay the difference in UK (not the full 25%)
- DTAA prevents double taxation
Popular fund categories:
- Large-cap equity funds (lower risk, steady growth)
- Index funds tracking Nifty 50 or Sensex
- Balanced/hybrid funds (mix of equity and debt)
- International funds (for further diversification)
Our team at Belong often sees UK NRIs choosing SIPs (Systematic Investment Plans) in diversified equity funds for long-term goals like children's education or retirement.
Fixed Deposits
Bank FDs remain popular for stability:
NRE FD:
- Funded from foreign earnings
- Interest: 6.5-7.5% annually
- Fully repatriable (principal + interest)
- Tax-free interest in India
NRO FD:
- Funded from Indian income (rent, pension, dividends)
- Interest: 6.5-7.5% annually
- Limited repatriation ($1 million per year)
- Interest taxable in India (30% TDS for NRIs)
FCNR FD:
- Held in foreign currency (USD, GBP, EUR)
- Interest: 4-5% annually
- Fully repatriable
- No exchange rate risk
- Tax-free interest in India
Compare rates easily using our NRI FD rates tool across HDFC Bank, ICICI Bank, SBI, and other major banks.

GIFT City Investments (Belong's Specialty)
Here's where we at Belong focus: GIFT City, India's International Financial Services Centre.
GIFT City USD FDs offer:
- USD-denominated deposits (no rupee depreciation risk)
- Tax-free returns in India (IFSCA-regulated, not RBI)
- Competitive rates (currently 4-5% in USD)
- Simplified repatriation compared to regular NRE/NRO accounts
- Regulatory safety: IFSCA (International Financial Services Centres Authority) oversight
Compare GIFT City FD vs NRE/NRO/FCNR to see why hundreds of UK and UAE NRIs are choosing this option.
We also offer Alternative Investment Funds (AIFs) through GIFT City for those seeking portfolio diversification beyond FDs.
👉 Tip: GIFT City products are ideal for UK NRIs who want currency hedge, tax efficiency, and simpler compliance compared to traditional Indian products.
Real Estate
Many UK NRIs invest in Indian property for rental income or future residence. RBI's regulations allow NRIs to buy residential/commercial property but not agricultural land.
Rental income from Indian property is taxable in India (30% for NRIs). When you sell property as an NRI, you pay capital gains tax, and buyers deduct TDS.
How Much Should UK NRIs Allocate to India?
This is the question that matters most.
Research from iNRI suggests that UK NRIs typically allocate 20-30% of their investable corpus to India, compared to:
- US NRIs: 5-10%
- Gulf NRIs: 40-50%
Why the difference? UK markets are mature and stable. US markets offer even better long-term returns. Gulf markets are less developed, making India relatively more attractive.
Factors That Determine Your Allocation
1. Retirement Location
Planning to retire in UK? Keep 70-80% in UK (ISA, pension, property). Planning to retire in India? Gradually shift to 50-60% in India over time. Undecided? Keep a balanced 50-50 split.
2. Age and Time Horizon
Age 25-35: Higher India allocation (30-40%) for growth. You have time to ride volatility.
Age 35-50: Balanced approach (20-30% India). Build both UK pension and Indian assets. Age 50-60: Lower India allocation (15-20%). Focus on stability and pound-denominated assets if retiring in UK.
3. Currency Risk
Rupee has historically depreciated 3-4% annually against GBP. If all your assets are in INR and you retire in UK, you lose purchasing power.
Our rupee vs dollar tracker (similar trends for GBP) shows this clearly.
Solution: Maintain currency diversification. GIFT City USD deposits offer this naturally.

4. Family Obligations
Supporting parents or children in India? You need rupee cashflows. Allocate higher to India.
Own property in India generating rent? That's already part of your India allocation.
5. Tax Efficiency
The UK-India DTAA prevents double taxation, but it doesn't make everything tax-free.
Consider:
- ISA growth is tax-free in UK, taxable in India after you return
- NRE FD interest is tax-free in India, potentially taxable in UK (though DTAA may exempt)
- UK pension income may be taxable in both countries depending on type
Consult a cross-border tax advisor. At Belong, we often recommend clients work with specialists in both jurisdictions.
Sample Allocation Strategies
Here are three personas we see often:
Persona 1: Young Professional (Age 30, London-Based Software Engineer)
Situation:
- Earns £80,000 annually
- Contributing 8% to workplace pension (employer adds 5%)
- Unsure if will return to India
- No immediate family obligations in India
Recommended Split:
- 60% UK: Max out ISA (£20,000), workplace pension, emergency fund in UK bank
- 30% India: SIP in equity mutual funds (₹30,000/month), NPS contribution (₹50,000/year for tax benefit)
- 10% GIFT City/USD assets: GIFT City FD or AIF for currency diversification
Why this works: At 30, she has time for equity growth. India allocation captures growth without overexposure. GIFT City provides hedge against rupee depreciation.
Persona 2: Mid-Career NHS Doctor (Age 45, Planning UK Retirement)
Situation:
- NHS pension accruing
- £200,000 in ISA already
- Parents in India need support
- Plans to retire in UK but visit India regularly
Recommended Split:
- 75% UK: Continue NHS pension, top up ISA, UK property/investments
- 20% India: NRE FDs for safety (₹50 lakh), small mutual fund SIP (₹20,000/month), maintain liquidity for parent support
- 5% GIFT City: USD FD (₹10 lakh) as emergency buffer and currency hedge
Why this works: NHS pension is his primary retirement vehicle. India allocation is defensive (FDs) with enough liquidity for family needs. GIFT City provides currency safety.
Persona 3: Senior Manager Planning India Return (Age 50, Manchester)
Situation:
- Plans to return to India in 5 years
- £400,000 across UK assets
- Property in Pune generating rent
- Wife will continue working in UK for 3 more years
Recommended Split:
- 50% UK: Keep ISA and pension (will need some GBP income for UK visits), UK property
- 40% India: Shift to debt mutual funds/FDs (safer as return nears), NPS for tax benefit, real estate
- 10% GIFT City: USD FD (₹30 lakh) for currency transition safety
Why this works: Gradual shift from GBP to INR exposure. Debt-heavy India allocation reduces volatility before return. GIFT City acts as bridge between currencies.
👉 Tip: These are illustrative. Use our Compliance Compass tool to check you're following all regulations for your specific situation.

Tax Implications: What You Must Know
While UK Tax Resident
On UK investments:
- ISA: Completely tax-free
- Workplace pension: Contributions get tax relief; withdrawals taxed as income
- State pension: Taxed as income in UK
- UK property rental: Taxed as income in UK
On India investments (while UK resident):
- India mutual fund gains: Taxable in UK as foreign income/gains
- NRE FD interest: Check if your tax return requires reporting (likely yes)
- India property rental: Taxable in both countries, but DTAA prevents double tax
According to HMRC guidelines, UK residents must file a Self Assessment if they have untaxed foreign income over £1,000 or if total income requires it; small foreign income may still need reporting under DTAA. (Source)
After Returning to India
On UK assets:
- ISA income/gains: Fully taxable in India
- UK pension income: Generally taxable in India per DTAA
- You can claim Foreign Tax Credit for any UK tax paid
On India assets:
- Resident tax rates apply (lower than NRI rates)
- You can now invest in products NRIs can't (like PPF, though NRIs can't open new PPF)
DTAA Benefits You Must Claim
The India-UK Double Taxation Avoidance Agreement ensures you don't pay full tax in both countries.
Example: You earn £10,000 rental income from UK property while living in India.
- UK taxes it at 20% = £2,000
- India would normally tax at 30%
- Under DTAA, you pay 30% in India but get credit for £2,000 already paid
- Net additional tax in India: 10% of £10,000 = £1,000
Read our guide on how to claim DTAA benefits for step-by-step instructions.
Common Mistakes UK NRIs Make
Mistake 1: Keeping ISA Open Without Purpose
If you're definitely moving back to India and won't return to UK, keeping a UK ISA means:
- Paying UK account fees
- Income becomes taxable in India
- Inheritance tax implications if UK domicile
- Complicated compliance for Indian tax filing
Consider liquidating and reinvesting in tax-efficient India products or GIFT City.
Mistake 2: Stopping UK Pension Contributions Too Early
You get tax relief on up to £3,600 annually for five years after leaving UK. That's essentially free money (20-45% boost). Many NRIs stop immediately, missing this benefit.
Mistake 3: Over-Investing in India Without Currency Hedge
A Manchester-based engineer we advised had 70% of his assets in INR. When he calculated retirement needs in GBP, rupee depreciation meant he'd fall short by 30%.
Solution: Maintain meaningful GBP/USD exposure through UK assets, GIFT City, or international funds.
Mistake 4: Not Converting Resident Accounts to NRE/NRO
Regular savings accounts become non-compliant once you're NRI. Convert them to NRE or NRO accounts or face penalties and operational issues.
Read our guide on converting resident accounts to NRI accounts.
Mistake 5: Ignoring Residential Status for Tax Planning
Your residential status in India determines taxation. Use our Residential Status Calculator before making any big investment decisions.
If you qualify as RNOR (Resident but Not Ordinarily Resident), you get beneficial tax treatment for up to 2 years after return.
👉 Tip: Review your allocation annually. Life changes-job, family, plans-and your investment mix should adapt accordingly.
Repatriation: Moving Money Between UK and India
From UK to India
Bank transfers via SWIFT are straightforward. Most UK NRIs use:
- Wise (formerly TransferWise): Low fees, mid-market rates
- Bank transfers: Higher fees but convenient
- Dedicated NRI services: ICICI UK, HDFC UK
Funds go to your NRE account (foreign earnings) or NRO account (if it's a gift/Indian-source income).
From India to UK
From NRE accounts: Fully repatriable, no limit. Transfer freely to UK bank.
From NRO accounts: Limited to $1 million per financial year. Requires Form 15CA/15CB and CA certificate if over certain limits.
From GIFT City: Simplified repatriation through IFSCA-regulated structure. One reason we at Belong favor this option for clients planning eventual UK return.
Read our detailed guide on repatriating funds from India.

Action Plan: What to Do Next
Step 1: Assess Your Current Situation
- Where are your assets now (UK vs India %)
- What's your likely retirement location
- What are your currency needs
- Check your residential status
Step 2: Determine Target Allocation Use the guidelines above based on age, retirement plans, and risk tolerance.
Step 3: Optimize UK Tax Wrappers
- Max out ISA contribution (£20,000/year) while UK resident
- Don't stop pension contributions prematurely
- Claim all tax reliefs available
Step 4: Build India Portfolio Systematically Don't dump lump sums. Use SIPs for mutual funds, stagger FD bookings, and gradually build exposure.
Step 5: Add Currency Hedge Consider GIFT City USD FDs or international funds. Don't keep 100% in single currency.
Step 6: Review Annually Life changes. So should your allocation. Set calendar reminder for yearly review.
Step 7: Get Expert Advice Cross-border financial planning is complex. Join our community, download our app, or consult with tax specialists in both countries.
The Bottom Line
There's no one-size-fits-all split for UK NRIs. The Manchester doctor retiring in London needs a different strategy than the Birmingham engineer moving back to Bangalore.
But here's what doesn't change: you need to think in two currencies, two tax systems, and two life stages. The UK offers stability and tax efficiency. India offers growth and connection.
The smartest UK NRIs we work with don't pick one over the other. They build portfolios that work in both worlds-maximizing ISAs and pensions while capturing India's growth through smart, tax-efficient products like GIFT City investments.
Start small, stay diversified, and review regularly. Your 30-year-old self and your 60-year-old self will thank you.
