About Investment Bonds
An investment bond is a tax-deferred investment wrapper issued by a life insurance company. You invest a lump sum, the insurer places it into one or more underlying funds on your behalf, and any growth inside the bond isn't taxed year by year in your hands. Despite the name, investment bonds have nothing to do with gilts or corporate bonds. They're technically single-premium life assurance policies, but their purpose is investment and tax planning rather than life cover.
Investment bonds come in two forms: onshore bonds, issued by UK insurers, and offshore bonds, issued by insurers based in jurisdictions like the Isle of Man, Dublin, or Luxembourg. Both let you withdraw up to 5% of your original investment each year without an immediate tax charge, both allow you to switch between funds inside the wrapper without triggering a taxable event, and both can be placed into trust for inheritance tax planning. There's no annual contribution limit and no restriction on access, which makes them useful once you've used your ISA and pension allowances for the year.
At Vintage Wealth Management, we look at investment bonds as part of a wider plan covering pensions, ISAs, tax planning, and protection. We assess whether an onshore or offshore bond suits your tax position, how the bond fits alongside your other wrappers, and how to structure withdrawals so you keep more of what the investment earns.
How do investment bonds work?
An investment bond works by investing your lump sum into one or more funds managed by a life insurance company. The bond grows or falls in value based on the performance of those funds, and any income or gains produced inside the wrapper are either untaxed or taxed internally by the insurer rather than in your hands. You don't need to declare anything on your tax return until a chargeable event occurs, which is usually when you withdraw more than your annual allowance, surrender the bond, or the last life assured dies.
Each investment bond is divided into a number of identical policies, known as segments, typically between 20 and 200. You can surrender individual segments without cashing in the whole bond, which gives you control over how much you access and when a taxable gain arises. You can also switch between funds inside the wrapper at any time without triggering a capital gains tax charge, something that isn't possible when holding investments directly or through a general investment account.
Most bonds require a minimum investment of £5,000 to £10,000, and you can withdraw up to 5% of your original investment each year on a tax-deferred basis, with unused allowance rolling forward. How that withdrawal rule works in practice, and what triggers a chargeable event, is covered in the taxation section below.
What types of investment bond are there?
There are two types of investment bond for UK investors: onshore and offshore. Both use the same life assurance wrapper, both offer the 5% tax-deferred withdrawal allowance, and both can be used for trust and estate planning. The difference is where the bond is issued and how the underlying fund is taxed.
Offshore
bonds
An offshore bond is issued by a life insurance company based outside the UK, typically in the Isle of Man, Dublin, or Luxembourg. The underlying fund pays little or no tax on income and gains as they arise, which means more of your money stays invested and compounds over time. This is known as gross roll-up.
When you withdraw, there's no basic rate credit. The full gain is taxed at your marginal income tax rate: 20% for basic rate, 40% for higher rate, 45% for additional rate. Offshore bonds work best if you expect to be in a lower tax bracket when you come to take money out, whether that's in retirement, after reducing your earnings, or because the gain is assessed on a trust beneficiary in a lower bracket.
Offshore bonds aren't covered by the FSCS. The Isle of Man operates its own policyholder protection scheme covering up to 90% of the bond's value if the insurer fails. Dublin-based bonds lost FSCS access after Brexit, and Ireland currently has no equivalent compensation scheme.
| EIS | SEIS | |
|---|---|---|
| Tax relief on contributions | None | 20%, 40%, or 45% |
| Tax on withdrawals | Tax-free | Income tax (after 25% tax-free lump sum) |
| Access | Anytime | From age 55 (rising to 57 from April 2028) |
| Annual allowance | £20,000 | £60,000 (tapered for high earners) |
| Inheritance tax | Part of estate | Part of estate from April 2027 |
| Lifetime limit | None | None (abolished April 2024) |
If you're a higher rate taxpayer now and expect to be basic rate when you withdraw, an offshore bond can produce a better after-tax return because the fund compounds without the 20% internal tax drag.
If you're likely to stay basic rate throughout, an onshore bond is simpler because the internal tax credit covers your full liability. For larger sums, the onshore bond's unlimited FSCS cover is worth factoring in.
We model the tax position for you before recommending one over the other, taking into account your income now, your expected income at withdrawal, and whether the bond will be held personally or inside a trust.
Onshore
bonds
An onshore bond is issued by a UK life insurance company. The underlying funds pay corporation tax internally at a rate equivalent to 20%, so the returns you see are net of that tax. When you cash the bond in, HMRC treats that 20% as already paid. A basic rate taxpayer has nothing more to pay. A higher rate taxpayer pays the difference between 40% and 20%. An additional rate taxpayer pays the difference between 45% and 20%.
Onshore bonds are classified as long-term insurance for FSCS purposes, which means 100% protection with no upper limit if the insurer fails. That's stronger cover than deposits (£120,000) or direct investments (£85,000).
They're widely used inside trust structures for inheritance tax planning, because the bond can be assigned to trustees without triggering a tax charge. They also suit investors who expect to be basic rate taxpayers when they withdraw, since the 20% internal tax credit covers the full liability.
Onshore vs
Offshore bonds
How are investment bonds taxed?
Investment bonds are taxed under the chargeable event regime. You don't pay capital gains tax on bond gains. Instead, any gain is treated as income and taxed at your marginal income tax rate when a chargeable event occurs. Between chargeable events, there's nothing to declare on your tax return.
What are the
ISA rules?
ISAs have a single set of rules that apply across all types, covering how much you can pay in, when you can transfer, and what happens if you withdraw. A few of them trip people up, particularly around transfers and flexible ISAs, so we've set them out in detail below
Allowance and contributions
Transfers
Flexible ISAs
Bed and ISA
The annual allowance, how you split it across ISA types, and the reset date are covered above in 'How do ISAs work.' You must be a UK resident and aged 18 or over to open an adult ISA. For a Lifetime ISA, you need to be between 18 and 39 to open one, though you can keep contributing until 50.
You can transfer ISA savings between providers and between ISA types without losing the tax-free status, and the transfer doesn't count against your annual allowance. Since April 2024, you can also transfer part of your current-year ISA balance to another provider. Previously, you had to move all or nothing for current-year subscriptions.
The important thing is to use the formal ISA transfer process through your new provider. If you withdraw the money yourself and pay it into a new ISA, it counts as a new subscription and uses up your allowance. For a non-flexible ISA, you'd also lose the tax-free status on the amount withdrawn. This is one of the most common mistakes people make with ISAs, and it's easily avoided.
A flexible ISA lets you withdraw money and replace it within the same tax year without the replacement counting as a new contribution. In a standard ISA, any withdrawal is gone from your allowance. If you've used your full £20,000 and take out £5,000, you can't put it back. In a flexible ISA, you can.
This is useful if you need short-term access to your savings but don't want to permanently lose part of your allowance. Not all providers offer flexible ISAs. Check before you open an account.
What happens to your ISA when you die?
Bed and ISA is the process of selling investments held outside an ISA and rebuying them inside your ISA wrapper. It's a way of gradually moving an existing portfolio into a tax-free environment using your annual allowance. The name comes from the older practice of "bed and breakfasting" shares for tax purposes.
The sale is a disposal for capital gains tax purposes, so you'll need to check whether the gain exceeds your £3,000 annual exemption before you sell. With the exemption as low as it is now, it often makes sense to spread bed and ISA transactions across multiple tax years to stay within the exemption each time. Getting the order and timing of disposals right can save you a lot in tax, and it's something we work through with you as part of your wider plan.
When you die, your ISA loses its tax-free status from the date of death, and the holdings become part of your estate for inheritance tax purposes. However, your spouse or civil partner can inherit an additional ISA allowance equal to the value of your ISA holdings at the date of death, known as an Additional Permitted Subscription (APS). This is on top of their own £20,000 annual allowance.
The APS means your surviving partner can effectively re-shelter the inherited savings in their own ISA, preserving the tax-free status. They have up to three years from the date of death, or 180 days after the administration of the estate is completed, whichever is later, to use it. This applies regardless of whether the inherited funds themselves are paid into the ISA, so your partner could use the APS allowance with their own money if they prefer.
What's changing
for ISAs in 2027?
The biggest change to ISAs takes effect on 6 April 2027. If you're under 65, the maximum you can pay into a Cash ISA will fall from £20,000 to £12,000 per year. The overall ISA allowance stays at £20,000, so the remaining £8,000 can be used in a Stocks and Shares ISA, Innovative Finance ISA, or Lifetime ISA. If you're 65 or over, nothing changes and you can still put the full £20,000 into cash.
The government is also introducing anti-avoidance measures alongside the cap. From April 2027, under-65s won't be able to transfer money from a Stocks and Shares ISA or Innovative Finance ISA into a Cash ISA. HMRC will introduce tests to identify "cash-like" investments held inside Stocks and Shares ISAs, and a charge on interest earned on uninvested cash held within investment ISA wrappers. The aim is to prevent savers from using investment ISAs as a way around the lower cash limit.
For anyone under 65 with significant cash savings, the 2026/27 tax year is the last opportunity to shelter up to £20,000 in a Cash ISA. If you've been using the full cash allowance each year, this is a good time to think about whether some of that money could sit in a Stocks and Shares ISA instead, particularly for savings you don't expect to need for five years or more. That's something we can help you work through as part of your wider financial plan.
Separately, the government has announced plans to replace the Lifetime ISA with a new First-Time Buyer ISA from April 2028. The replacement is expected to remove the retirement savings function and scrap the 25% withdrawal penalty, but the consultation is still underway and the details haven't been finalised. Existing LISAs will remain open and you can continue contributing to them.
How do ISAs compare to
pensions?
ISAs and pensions are both tax-efficient wrappers, but they work differently and suit different purposes. Most people benefit from using both, and the balance between them depends on your age, income, tax position, and when you'll need access to the money.
A pension gives you tax relief on the way in. Basic-rate taxpayers get 20% relief, higher-rate taxpayers can claim 40%, and additional-rate taxpayers 45%. Your employer may also contribute on your behalf. But your money is locked away until you reach the minimum pension age, currently 55 and rising to 57 from April 2028. When you draw it as income, it's taxed at your marginal rate after the 25% tax-free lump sum.
An ISA gives you no tax relief on contributions, but everything you take out is tax-free. There's no restriction on when you can access the money, no limit on how much you can withdraw, and no income tax when you do. For someone who expects to be a higher-rate taxpayer in retirement, or who wants flexibility before pension age, ISAs can be more tax-efficient than additional pension contributions above the employer match.
The two also differ on inheritance tax. From April 2027, most unused pension funds will be brought into the estate for inheritance tax purposes. ISA holdings are already part of your estate, but they benefit from the Additional Permitted Subscription for spouses, which lets your partner re-shelter the value in their own ISA. Neither wrapper is better in every situation, and the balance between the two shifts as your income, tax position, and retirement plans evolve. We help you work out that balance as part of your wider plan.
| EIS | SEIS | |
|---|---|---|
| Tax relief on contributions | None | 20%, 40%, or 45% |
| Tax on withdrawals | Tax-free | Income tax (after 25% tax-free lump sum) |
| Access | Anytime | From age 55 (rising to 57 from April 2028) |
| Annual allowance | £20,000 | £60,000 (tapered for high earners) |
| Inheritance tax | Part of estate | Part of estate from April 2027 |
| Lifetime limit | None | None (abolished April 2024) |

Frequently asked questions about investment bonds
-
The 5% rule lets you withdraw up to 5% of your original investment each policy year without an immediate income tax charge. The allowance is cumulative, so unused years roll forward. These withdrawals are tax-deferred, not tax-free. All amounts taken are added back into the gain calculation when the bond is eventually surrendered.
-
After 20 years of withdrawing 5% per year, you'll have taken back 100% of your original investment as cumulative tax-deferred allowance. Any further withdrawals will trigger a chargeable event and be subject to income tax. The bond itself can continue indefinitely, but once the 5% allowance is exhausted, there's no further tax-deferred access.
-
No. Investment bonds are tax-deferred, not tax-free. You don't pay tax while the bond is in force, but when a chargeable event occurs the gain is taxed as income at your marginal rate. For onshore bonds, a 20% basic rate credit is treated as already paid. For offshore bonds, there's no credit and the full gain is taxed.
-
No. Investment bonds don't pay interest or dividends to the bondholder. Any income generated by the underlying funds stays inside the wrapper. The bond is classified as a non-income producing asset for tax purposes. You access your money through the 5% tax-deferred withdrawal facility or by surrendering segments or the whole bond.
-
The value of the underlying funds can fall as well as rise, and you could get back less than you invested. Charges from the insurer and underlying fund managers reduce your return over time. Withdrawing more than your cumulative 5% allowance can trigger an unexpected tax bill, even if the bond has fallen in value. Offshore bonds aren't covered by the FSCS, so investor protection depends on the jurisdiction.
-
Investment bonds carry charges that can be higher than holding funds directly or through a platform. The 5% withdrawal allowance is tax-deferred, not tax-free, and the deferred tax can catch people out on surrender. You can't claim capital losses on a bond the way you can on direct investments. And for basic rate taxpayers with unused ISA allowance, a bond is rarely the most tax-efficient option.
-
Investment bonds can work well as part of a retirement income strategy. The 5% tax-deferred withdrawal provides a regular income without an immediate tax charge, and if you're a higher rate taxpayer before retirement and a basic rate taxpayer after, the timing of withdrawal can reduce your overall tax bill. They sit alongside pensions and ISAs rather than replacing them. Vintage Wealth Management builds retirement income plans that use all three wrappers together.
