Financial planners often call these tax wrappers. A wrapper is simply the legal account that holds your investments. It doesn't usually change the investment itself, but it can have a significant impact on how it's taxed.

This guide covers every major tax wrapper available in the UK — what each one does, what it's commonly used for, and what to watch out for. It's a reference to search and compare, not a book to read cover to cover.

Same fund. Same manager. Same underlying holdings. Only the tax treatment changes — because a pension isn't an investment, it's a container.

Compare every wrapper at a glance

*Pensions are currently outside the estate for inheritance tax. The government has legislated bringing unspent pensions within the estate from April 2027.

What is it?

A pension is the most tax-efficient long-term savings vehicle available to most people. This covers personal pensions and standard SIPPs.

A SIPP (Self-Invested Personal Pension) is a personal pension that gives you direct control over where your money is invested, with access to a wider range of funds, shares and other assets than a standard personal pension. The tax rules are identical to a personal pension. Full SIPPs and SSASs have materially different investment capabilities and are covered in their own sections.

Although pensions are currently outside the estate for IHT purposes, from April 2027 unspent pensions will be within the estate and therefore liable to IHT.

Why does it exist?

Pensions exist to encourage long-term saving for retirement, in exchange for generous tax incentives: relief on contributions, tax-free growth inside the wrapper, and flexible access from a set minimum age.

Key features

Contributions and tax relief. You can personally contribute up to 100% of your UK earnings per year, or £3,600 gross if you earn less. The standard annual allowance is £60,000 (2026/27), covering personal and employer contributions combined.

Contributions attract income tax relief at your marginal rate. For most people this works automatically through relief at source: you pay 80% and the provider claims the remaining 20% from HMRC. Higher and additional rate taxpayers can claim further relief through self-assessment. A 40% taxpayer making an £8,000 net contribution effectively pays just £6,000 after reclaiming higher rate relief.

The chart below shows exactly what this looks like for a £10,000 gross pension contribution, across four different tax positions. £10,000 always ends up in the pension — what changes is how much of that actually comes out of your own pocket once every layer of relief is accounted for.

Notice how little changes mechanically between bands — the same £8,000 leaves your account and the same £2,000 is added automatically every time. The only thing that changes is how much of that £8,000 you get back later through your tax return, which is why higher and additional rate taxpayers should never assume their pension relief is "done" once the provider's basic rate top-up lands — the rest has to be actively claimed.

Employer contributions count towards the annual allowance but don't attract personal tax relief — they're simply a cost to the employer, paid gross.

Unused annual allowance from the previous three tax years can often be carried forward, subject to sufficient earnings.

The tapered annual allowance. For high earners, the allowance reduces gradually. If threshold income exceeds £200,000 and adjusted income exceeds £260,000, the allowance reduces by £1 for every £2 of adjusted income above £260,000, down to a minimum of £10,000.

The £100,000 trap. Between £100,000 and £125,140, the personal allowance is withdrawn at £1 for every £2 of income — an effective marginal rate of 60%. As the chart above shows, a £10,000 gross pension contribution in this band can cost as little as £4,000 out of pocket once all relief is accounted for — some of the most powerful relief available anywhere in the tax system. Pension contributions that bring income below £100,000 restore the personal allowance and can be extraordinarily tax-efficient.

Tax treatment

Investments inside a pension grow completely free of income tax and capital gains tax. On withdrawal, 25% is tax-free (subject to the lump sum limit) and the remaining 75% is taxed as income at your marginal rate in the year it's withdrawn. Spreading withdrawals across tax years can reduce the overall tax paid.

What is it?

An ISA is the simplest and most flexible tax-efficient wrapper available. Money invested in an ISA grows completely free of tax, and withdrawals are entirely tax-free — with nothing to declare on a tax return.

Why does it exist?

ISAs exist to make tax-efficient saving and investing simple and accessible, without the complexity or access restrictions of a pension.

Key features

Types of ISA:

• Stocks and Shares ISA — investments in funds, shares, bonds and other assets. The most common choice for long-term wealth building.
• Cash ISA — savings held as cash, earning interest tax-free.
• Innovative Finance ISA (IFISA) — peer-to-peer lending and similar investments. Higher risk and less widely used.
• Lifetime ISA and Junior ISA — see their own sections.

Contribution limits. The annual ISA allowance is £20,000 per person per tax year (2026/27), currently splittable across ISA types in any combination, but capped at £20,000 in total. Unused allowance cannot be carried forward.

Change from April 2027. From 6 April 2027, no more than £12,000 of the £20,000 allowance will be able to go into a Cash ISA. The remaining £8,000 (or more) will need to go into a Stocks and Shares ISA or another non-cash ISA type — cash alone will no longer be able to use the full £20,000 allowance.

Flexible ISAs allow you to withdraw and replace funds in the same tax year without losing your allowance. Standard ISAs allow withdrawals at any time, but the allowance isn't replenished.

Tax treatment

There's no upfront tax relief — you invest money that's already been taxed. In return, dividends, interest and capital gains inside an ISA are all completely tax-free, and withdrawals are tax-free at any age.

What is it?

The Lifetime ISA is designed for two specific purposes: buying a first home or saving for retirement. Outside these two uses, it's relatively inflexible.

Why does it exist?

Introduced to help younger people save for a first home or supplement retirement saving, with a bonus generous enough to meaningfully boost either goal.

Key features

Who can use it. You must be aged 18–39 to open a LISA, and can contribute until age 50.

Contribution limits. Up to £4,000 per year, which counts within the overall £20,000 ISA allowance.

Government bonus. The government adds 25% on top of contributions, up to £1,000 per year. Over a full lifetime of contributions from 18 to 50, the maximum total bonus is £32,000.

Tax treatment

Growth is tax-free, like other ISAs. Permitted withdrawals — a first home purchase (property value £450,000 or less), from age 60, or on terminal illness — are entirely tax-free, with the bonus retained.

Withdrawing for any other reason triggers a 25% government charge. This erodes more than just the bonus: £4,000 contributed plus a £1,000 bonus becomes £5,000, and a 25% charge on that is £1,250 — leaving £3,750 from an original £4,000 contribution.

What is it?

A GIA is a standard investment account with no tax wrapper. It has no contribution limits, no restrictions on withdrawals, and no special tax treatment — gains and income are subject to normal capital gains tax and income tax rules.

Why does it exist?

A GIA exists simply as the default, unrestricted way to hold investments once tax-efficient allowances are exhausted, or where flexibility matters more than tax shelter.

Key features

Contribution limits. None.

Tax on growth. Capital gains are taxed when investments are sold. Each individual has an annual CGT exemption of £3,000 (2026/27); gains above this are taxed at 18% (basic rate) or 24% (higher/additional rate) for most investments.

Income (dividends and interest) is taxed at income tax rates, subject to the dividend allowance (£500 in 2026/27) and personal savings allowance.

Tax treatment

No special treatment — gains are subject to CGT at the time of disposal, and income is taxed in the normal way.

What is it?

An offshore bond is a life insurance policy issued by a provider in a low-tax jurisdiction (typically Ireland or the Isle of Man). Unlike an onshore bond, income and gains accumulate within the policy gross — without deduction of UK tax at source.

Why does it exist?

Offshore bonds exist to let higher and additional rate taxpayers defer tax on investment growth, often until a year when they expect to pay a lower rate — such as retirement.

Key features

Contribution limits. None, though very large contributions may need provider approval.

The 5% rule. You can withdraw up to 5% of the original premium each year, cumulatively, without an immediate tax charge. This is a deferral, not an exemption — the gain is eventually taxed on full surrender or when withdrawals exceed the cumulative allowance. Unused allowance carries forward, so taking nothing for five years allows a 25% withdrawal later without triggering a chargeable event.

Segments. Offshore bonds are typically written in multiple segments (often 100+). Surrendering individual segments, rather than the whole bond, allows precise management of the chargeable event gain in any given year.

Tax treatment

When a chargeable event occurs — full surrender, exceeding the 5% allowance, or death — the gain (surrender value + withdrawals − premiums − previous gains) is taxed as income at your marginal rate. No 20% notional tax credit applies (unlike onshore).

Top slicing example. An investor surrenders after 10 years with a £50,000 gain, on £40,000 of other income. Without top slicing, the full gain stacks on top of income, pushing much of it into the 40% band. With top slicing, the gain is divided by 10 years — a £5,000 "slice" — keeping the total comfortably within the basic rate band, so the effective rate on the whole gain is 20%, not 40%.

What is it?

An onshore bond is similar to an offshore bond but is issued by a UK insurance company and is subject to UK corporation tax within the fund (currently 20%). This means growth isn't entirely gross — there's an element of tax within the bond, equivalent to basic rate tax.

Why does it exist?

Onshore bonds exist as a UK-based alternative to offshore bonds, trading some gross growth for a built-in tax credit that can fully settle a basic rate taxpayer's liability on surrender.

Key features

The 5% rule, top slicing relief and segment structure all work the same way as an offshore bond.

Tax within the fund. The bond pays corporation tax internally, which acts as a basic rate tax credit. When a chargeable event gain arises, basic rate taxpayers pay no further tax — the internal tax is treated as having already settled their liability. Higher rate taxpayers pay the difference between their marginal rate and 20%; additional rate taxpayers pay an extra 25%.

Tax treatment

The gain is added to income with a notional 20% basic rate credit applied. No further tax for basic rate taxpayers; higher rate taxpayers pay an additional 20% on the gain; additional rate taxpayers pay an additional 25%.

What is it?

A VCT is a listed company that invests in early-stage UK businesses. It offers significant tax incentives in exchange for taking on higher investment risk.

Why does it exist?

VCTs exist to channel investment into small UK businesses that would otherwise struggle to raise capital, with generous tax relief compensating investors for the higher risk.

Key features

Contribution limits. Up to £200,000 per tax year.

Income tax relief. 20% upfront relief on new VCT subscriptions, provided shares are held at least five years. A £10,000 investment costs an effective £8,000 after relief.

Tax-free dividends. VCT managers typically aim to return value through regular tax-free dividends, commonly targeting 3–5% yields, though this isn't guaranteed and depends on the underlying portfolio's performance.

Tax treatment

Dividends from VCTs are tax-free, and capital gains on disposal are tax-free. Selling before five years claws back the income tax relief.

What is it?

EIS offers tax relief for investment in qualifying small and medium-sized UK companies. It's higher risk than a VCT but offers more generous relief.

Why does it exist?

EIS exists to direct private capital into smaller UK companies with strong growth potential, using relief generous enough to compensate for the elevated risk of investing directly in individual early-stage businesses.

Key features

Contribution limits. Up to £1,000,000 per tax year (£2,000,000 for knowledge-intensive companies).

Income tax relief. 30% upfront relief, provided shares are held at least three years.

Loss relief. If EIS shares fall in value, losses can be offset against income, not just capital gains — making the downside more manageable.

Tax treatment

Gains on shares held three years or more are completely CGT-exempt. EIS can also defer capital gains from other disposals — reinvesting a gain into EIS shares defers the CGT until the EIS shares are sold. If the investor dies while still holding the shares, the deferred gain is wiped out entirely rather than crystallising, which makes EIS deferral a genuinely powerful estate planning tool.

EIS shares also qualify for Business Relief after two years, meaning they can pass on free of inheritance tax.

What is it?

SEIS is the smaller company equivalent of EIS, targeting very early-stage businesses. The tax reliefs are more generous to reflect the higher risk.

Why does it exist?

SEIS exists to support the very earliest stage of UK company formation, where the funding gap and risk are both greatest — hence the most generous relief available in the tax system.

Key features

Contribution limits. Up to £200,000 per tax year.

Income tax relief. 50% upfront relief — a £10,000 investment costs an effective £5,000.

Loss relief. As with EIS, losses can be offset against income.

Tax treatment

CGT-free on disposal after three years. Gains from other disposals reinvested into SEIS qualify for 50% CGT reinvestment relief — meaning half the gain is permanently exempt, not merely deferred, which is more generous than EIS's deferral-only treatment. SEIS also qualifies for Business Relief after two years.

What is it?

Business Relief is not a wrapper in itself, but a tax relief that can apply to qualifying investments — typically shares in AIM-listed companies or unlisted trading businesses. After holding qualifying investments for two years, they become exempt from inheritance tax.

Why does it exist?

Business Relief (formerly Business Property Relief) exists to protect trading businesses from being broken up to pay inheritance tax. Investing in qualifying shares lets individuals access the same relief as part of an estate planning strategy.

Key features

IHT treatment. After a two-year holding period, qualifying BR investments attract 100% IHT relief, subject to a cap of £2.5 million per individual (£5 million for a married couple, as the cap transfers to a surviving spouse). Above the cap, the excess is taxed at the standard IHT rate. AIM-listed shares attract 50% relief, not 100%.

If you sell a BR-qualifying investment and reinvest within three years, the two-year qualifying period doesn't restart — the original clock continues. This gives meaningful flexibility to switch providers or strategies without losing accumulated benefit.

Tax treatment

Unlike a gift into trust, BR investments remain in your name and can be accessed at any time — though selling or spending the assets removes the relief. Capital gains tax applies on disposal, and income is taxed normally; the benefit is specifically on the IHT side.

What is it?

A Full SIPP is a more powerful variant of the standard SIPP, offering a significantly wider investment universe — including commercial property — not available through a standard or low-cost SIPP platform.

Why does it exist?

Full SIPPs exist for individuals who want the additional capability to hold commercial property within a pension, without needing the full complexity of an employer-sponsored SSAS.

Key features

Key additional capability. A Full SIPP can purchase commercial premises — including a business's own offices or trading premises — and lease them back to the business. Rental income accumulates tax-free within the scheme, and the property is held within the pension rather than the business.

Borrowing. A Full SIPP can borrow up to 50% of its net asset value to fund property purchases — the same facility available within a SSAS. A Full SIPP with £500,000 of assets could borrow up to £250,000 to help fund a commercial property acquisition.

Compared to a SSAS. Both can hold commercial property and borrow up to 50% of NAV. The key differences are governance: a SSAS is an employer-sponsored trust with collective trustee control and the ability to loan money back to the sponsoring employer, which a Full SIPP cannot do. A Full SIPP is simpler to administer and doesn't require a sponsoring employer.

Tax treatment

All the same pension tax rules apply — contributions, tax relief, annual allowance, access from age 55 (rising to 57 in 2028), 25% tax-free cash, income tax on withdrawals, and death benefit rules are identical to a standard pension.

What is it?

A SSAS is an occupational pension scheme set up by a company — typically a small, owner-managed business — for its directors and key employees. It's fundamentally different from a personal pension or SIPP in structure, governance and the range of things it can do.

Why does it exist?

SSASs exist to give business owners a pension structure with genuine control over investment decisions and a direct financial relationship with their own company, including the ability to lend the scheme's assets back to the business.

Key features

Who can use it. A SSAS is established by the sponsoring employer. Members are typically the business owners and directors, though other employees can be included — there's no minimum number of members, and many schemes have just one or two.

Contributions. The same £60,000 annual allowance rules apply (2026/27). Employer contributions receive corporation tax relief; member contributions attract income tax relief as with any personal pension. Carry forward applies in the same way.

Loan-back to the sponsoring employer. One of the most distinctive features — up to 50% of the scheme's net assets can be loaned to the employer, subject to strict conditions: the loan must be secured on assets of equal value, carry a commercial interest rate, and be repaid within five years (with an option to renew).

Commercial property. A SSAS can purchase commercial property, including the business's own premises, and lease it back to the company. Rental income grows tax-free within the scheme, and the property passes to the pension on the company's ownership changing rather than forming part of the business's assets.

Tax treatment

Investments grow completely free of income tax and capital gains tax within the scheme, as with any pension. Access follows the same rules — from age 55 (rising to 57 in 2028), with up to 25% tax-free and the remainder taxable as income.

What is it?

A Junior ISA is an ISA held in a child's name. It cannot be accessed until the child turns 18.

Why does it exist?

Designed to let parents, grandparents and other family members save tax-efficiently for a child's future, replacing the older Child Trust Fund scheme.

Key features

Contribution limits. £9,000 per tax year (2026/27). Anyone can contribute, subject to the annual limit.

Types. Stocks and shares JISA or cash JISA, as with adult ISAs.

Access. The child can take control of the account at 16 but cannot withdraw funds until 18, when it automatically converts to an adult ISA. There's no early access, unlike a Child Trust Fund.

Tax treatment

Growth and withdrawals are entirely tax-free, exactly as with an adult ISA.

What is it?

A Junior Pension — usually structured as a Junior SIPP — is a personal pension opened in a child's name by a parent or legal guardian. It works on the same tax rules as an adult pension, just started decades earlier.

Why does it exist?

Junior Pensions exist to let families use a child's own pension allowance from birth, giving compound growth the longest possible runway before retirement.

Key features

Who can contribute. A parent or legal guardian must open the account, but anyone — parents, grandparents, other family — can contribute.

Contribution limits. Up to £3,600 gross per tax year (2026/27), the same allowance that applies to anyone without earnings. In practice this means contributing £2,880, with the pension provider automatically claiming £720 of basic rate relief to make it up to £3,600 — even though the child has no income of their own.

Ownership. The child becomes the beneficial owner of the pension, but has no ability to access, manage or even see the account until they're old enough to do so as an adult.

Tax treatment

Exactly as with an adult pension: contributions receive basic rate tax relief automatically, investments grow completely free of income tax and capital gains tax, and on withdrawal — decades from now — 25% is tax-free with the remainder taxed as income at the child's marginal rate at the time.

What is it?

Child Trust Funds are no longer available to new applicants (replaced by Junior ISAs in 2011), but many adults now hold CTF accounts that were opened for them as children.

Why does it exist?

CTFs were the government's original tax-free children's savings scheme, later replaced by the more flexible Junior ISA.

Key features

Existing CTF accounts continue to operate on broadly the same tax-free basis as when they were opened, and can still receive contributions from family members up to the same annual limit as a JISA.

Tax treatment

Growth within the CTF is tax-free, and withdrawals are tax-free, matching Junior ISA treatment.

What is it?

Help to Buy ISAs are closed to new applicants (closed November 2019). Existing account holders can continue to save and claim the government bonus when purchasing a qualifying first home.

Why does it exist?

Introduced to help first-time buyers save a deposit, later replaced by the Lifetime ISA for new savers.

Key features

Government bonus. 25% bonus on savings, up to £3,000 in total (based on £12,000 of savings).

Tax treatment

Growth is tax-free, matching other cash ISAs. The bonus is paid on completion of a qualifying first home purchase (property value up to £250,000, or £450,000 in London), and cannot be used alongside a Lifetime ISA bonus on the same purchase.
