How Can I Reduce the Tax on My Investments?
Key takeaways
- Start with allowances and ownership. ISAs, CGT exemptions, losses and genuine spousal transfers can improve tax efficiency.
- Tax deferral is different from tax exemption. Offshore bonds offer timing options, but future tax and charges still matter.
- Borrowing adds costs and risk. Lombard lending can postpone a sale, but interest, repayment and collateral requirements remain.
- Specialist relief does not remove investment risk. EIS, VCTs and SEIS need separate suitability and eligibility checks.
- Review the whole portfolio. Aim for a better outcome after tax and costs, with access and risk matched to your goals.
A £2 million investment portfolio can be invested sensibly and still be structured inefficiently for tax. Dividends, interest, realised gains and the way you access capital can all affect how much of the return you keep.
The answer is usually a combination of allowances, ownership, tax wrappers and withdrawal planning. The aim is to improve your after-tax position without taking risks, paying charges or giving up access that outweigh the benefit.
Here are the main options I would want a UK-resident investor to understand, followed by an interactive £2 million portfolio example.
Start with the tax your investments actually generate
Portfolio growth is not all taxed in the same way. Dividends and interest can create annual liabilities even when reinvested. Capital gains normally arise when assets are disposed of; a rising valuation alone does not normally trigger CGT on a conventional investment account.
For the current 2026/27 tax year, the individual CGT exemption is £3,000 and the dividend allowance is £500. Main individual CGT rates are 18% and 24%; dividend rates are 10.75%, 35.75% and 39.35%. Check the applicable rules in HMRC’s CGT guidance and dividend guidance.
Use ISAs consistently
An eligible adult can subscribe up to £20,000 to ISAs each tax year. Investment income and gains inside an ISA are exempt from UK income tax and CGT. Two eligible spouses or civil partners could therefore subscribe £40,000 between them, provided neither has used the allowance elsewhere. See how ISAs work.
That will not shelter £2 million overnight, but repeated subscriptions can build a substantial protected pool. A “Bed and ISA” normally involves selling investments outside the ISA and buying inside it: the initial sale can trigger CGT. It is not a tax-free transfer of an existing portfolio. HMRC explains the share-exchange rules.
Use CGT allowances, losses and genuine spousal ownership
Plan disposals rather than leaving all gains until a large cash withdrawal is needed. Available exemptions, allowable losses and the timing of sales across tax years may help. Unused annual CGT exemptions cannot be carried forward, while properly claimed losses can remain useful. Check HMRC’s loss rules.
Transfers between spouses or civil partners living together normally take place on a no-gain/no-loss basis. The recipient takes over the relevant tax cost; the gain does not disappear. A genuine transfer before a sale may allow both owners’ exemptions or different tax bands to be used. Ownership, income rights and control must actually change. These rules do not extend automatically to unmarried partners. See HMRC’s spousal-transfer guidance.
Selling and immediately repurchasing the same shares outside an ISA is not a simple allowance reset: same-day and 30-day matching rules can apply. HMRC’s share-matching guide explains why transaction records matter.
Check pension funding before adding complexity
Pensions can provide contribution relief and shelter investment growth, but the money is normally inaccessible until the relevant pension-access age and later withdrawals can be taxable. The standard annual allowance is £60,000, including employer contributions and other pension input; tapering or the money purchase annual allowance can reduce it. Carry forward may help where eligible.
Personal contribution relief is also constrained by relevant earnings, with limited provision for non-earners. Having a £2 million portfolio does not itself create pension contribution capacity. Review the pension allowances and contribution relief rules.
Consider an offshore bond for the right part of the portfolio
An offshore investment bond can allow income and gains to accumulate without annual UK personal tax on the underlying activity. Switching permitted funds within the bond normally does not create a personal CGT liability. Underlying withholding taxes and product, investment and advice charges can still apply. Canada Life explains the structure.
The benefit is primarily control over the timing of personal taxation. Withdrawals within the cumulative 5% facility are tax-deferred, not tax-free. Later chargeable-event gains are generally taxed as income rather than capital gains, so your CGT exemption and capital losses cannot offset them. Top slicing relief may help, but is not automatic. See HMRC’s foreign-policy helpsheet.
Compare the eventual tax, charges and access strategy with a general account and other wrappers. Selling existing holdings to fund a bond can itself crystallise gains. My offshore bond guide covers the wider considerations; gifting whole segments can also form part of an appropriate family plan.
Explore a £2 million portfolio
Assume two spouses genuinely own £1 million each, both remain higher-rate taxpayers, and their allowances are unused. A combined 2% dividend yield and 1% interest yield produces £40,000 of dividends and £20,000 of interest. Under the simplified assumptions below, annual income tax is £21,542.50. Separate realised gains of £20,000 produce £3,360 of CGT.
Subscribing £40,000 to their ISAs at the start of the year reduces the illustrated full-year income-tax bill by £446, assuming unchanged investments and yields. That is one year’s effect, not a claim that an ISA subscription removes the whole tax bill. Any tax from funding the subscription needs a separate calculation.

Start with a £2 million portfolio. Explore annual tax and ISA allowances, then compare selling investments with borrowing against them.
Illustrative UK personal-investment figures using 2026/27 rules, checked 29 October 2026. This is not a full tax calculation or a recommendation. It assumes your Personal Allowance is already used and all taxable investment income stays within the selected band. It does not calculate band crossings or allowance tapering. Do not use the higher-rate setting if the added income would push you into the additional-rate band.
The wrapper comparison assumes funding at the start of a full year and unchanged underlying yields, before extra charges or withholding taxes. It excludes CGT and dealing costs from selling assets to fund an ISA or bond. The CGT figure is separate and is not reduced automatically by allocations. The bond figure illustrates current personal-tax deferral only, with no withdrawals, surrender or future bond tax; it is not a net benefit. Pensions, EIS and VCT reliefs are not calculated. Yields and gains are assumptions, not forecasts; values can fall.
Compare a sale with Lombard borrowing
A loan can postpone a disposal, but the debt and interest remain. This comparison does not say borrowing is better or calculate a permanent tax saving.
The sale is grossed up to leave the same net cash after CGT; it assumes a constant embedded-gain percentage across the assets sold. Loan costs use simple interest, a constant principal and rate, with fees paid separately. No tax deduction for interest is assumed. No investment returns, future tax, currency changes, lender haircuts, margin calls or forced sales are calculated. The principal remains repayable. Loan-to-value is not a lending offer or a margin-call threshold. Lenders can demand more collateral, repayment or sell investments.
Lombard lending: a liquidity tool, not tax-free income
A Lombard loan is secured against eligible investments. Borrowing instead of selling can postpone a disposal and its CGT, but it does not remove the gain. Interest and fees must be paid, the principal repaid and collateral maintained. A market fall can lead to a demand for additional security or repayment, and potentially forced sales. Weatherbys describes the mechanics and risks.
In the calculator’s separate example, raising £100,000 after CGT from assets whose value includes a 40% gain requires a gross sale of about £110,619 at a 24% rate, with no exemption remaining. Borrowing £100,000 at an assumed 6% for a year costs £6,000 interest, plus the illustrative £1,000 fee, with the debt still outstanding. Those figures are not a permanent tax saving or a complete comparison of future wealth.
Borrowing needs a credible repayment plan and stress testing. It is not a substitute for a sustainable income strategy, and personal borrowing interest should not be assumed deductible against investment income.
EIS, VCTs and SEIS: relief with substantial investment risk
EIS: qualifying new shares can attract 30% income-tax relief. Qualifying investment gains may be exempt after the required holding period, normally at least three years. EIS can also defer a separate capital gain, but that deferred gain can return to charge. HMRC distinguishes these CGT reliefs.
VCTs: qualifying new subscriptions currently attract 20% income-tax relief, reduced from 30% from 6 April 2026. The annual qualifying limit is £200,000 and shares normally need to be held for five years to retain upfront relief. Qualifying dividends are tax-free. See the VCT relief change.
SEIS: qualifying subscriptions can attract 50% income-tax relief on up to £200,000 per tax year, subject to detailed conditions. For all these schemes, eligibility, sufficient income-tax liability, qualifying shares and continuing conditions matter. Relief can be withdrawn. Check HMRC’s investor guidance.
These investments support smaller businesses and can be illiquid, expensive and capable of losing all the capital invested. A minimum tax holding period does not guarantee an exit. A £30 tax relief does not make a £100 investment safe. They require specialist suitability work and should not displace a sensible core portfolio simply to reduce a tax bill. The FCA explains high-risk investment risks.
Other opportunities worth reviewing
- Asset location and direct gilts. Consider which assets belong in each wrapper. Direct qualifying UK gilts are CGT-exempt, although coupons are generally taxable. Low-coupon gilts bought below redemption value can therefore merit comparison for planned spending. Prices can fall, and a gilt fund does not inherit the same personal CGT exemption. See HMRC’s gilt guidance.
- Charitable gifts. Where giving is already your intention, donating qualifying investments can offer income-tax and CGT relief. You relinquish the asset; it is not a way to retain the money. See HMRC’s charitable-giving guidance.
- Fund choice, turnover and costs. Accumulation units do not automatically avoid income tax. Tax records, fund reporting status, unnecessary trading and total charges deserve attention.
- Companies, trusts and succession planning. These may serve family governance or estate goals, but have their own taxes and administration. Moving an existing personal portfolio can trigger tax, and company profits may face further tax when extracted. They need bespoke analysis.

I start with what your money needs to do: spending, retirement, family support and the risks you can afford. With more than 20 years’ experience, I use Strategic Financial Planning to coordinate the investment structure with those goals, working with your tax and legal advisers where needed.
The right question is how much you keep after tax and costs, with suitable access and risk—not simply which product advertises the largest relief.
General information, not a personal recommendation or tax or legal advice. Rates and allowances refer to 2026/27 and were checked on 29 October 2026; future changes are not included in the calculator. Tax treatment depends on circumstances and can change. Investments can fall as well as rise, and you may get back less than invested. Specialist investments and borrowing are unsuitable for many investors. Obtain advice before acting.
Frequently Asked Questions
How can I reduce the tax on a £2 million investment portfolio?
Review how much income and realised gain the portfolio generates, then consider ISA and pension capacity, available CGT exemptions and losses, genuine spousal ownership and appropriate investment structures. The right combination depends on your income, access needs, existing tax costs and risk tolerance.
Are offshore bond withdrawals tax-free?
No. Withdrawals within the cumulative 5% facility are normally tax-deferred, not tax-free. A later chargeable-event gain may be taxable as income. Charges, policy history, withdrawal method and personal circumstances need to be considered.
Can Lombard lending help me avoid selling investments?
An eligible portfolio can secure borrowing, which may postpone a disposal and its CGT. It does not erase the gain or create tax-free investment income. Interest and fees apply, the principal must be repaid and market falls can lead to collateral demands or forced sales.
Can transferring investments to my spouse reduce CGT?
Transfers between spouses or civil partners living together normally take place on a no-gain/no-loss basis. A genuine change of ownership can allow both owners’ available exemptions or tax bands to be considered before a later sale. The underlying tax cost transfers too; the gain does not reset.
Do EIS and VCT investments offer the same tax relief?
No. For qualifying new subscriptions, EIS currently offers 30% income-tax relief, while VCT relief is 20% from 6 April 2026. Holding periods and other reliefs differ. Eligibility, sufficient income-tax liability and continuing conditions matter, and both involve substantial investment and liquidity risk.
