| UK tax concept or relief | Statutory basis and HMRC manual | How it works for a UK resident |
|---|---|---|
| Gross roll-up and chargeable events | ITTOIA 2005 Part 4 Chapter 9, s.461 (the charge) and s.484 (chargeable events); IPTM3000 | Income and gains inside the policy are not taxed on you year by year; withholding tax on some foreign dividends, which the insurer cannot reclaim, is the only leak. UK income tax is deferred until a chargeable event: a full surrender, a withdrawal above the 5% allowance, an assignment for money, maturity or the death that ends the policy. How offshore bonds are taxed. |
| The 5% tax-deferred withdrawal allowance | ITTOIA 2005 s.507; HS321 | Up to 5% of each premium can be taken out in every policy year, cumulatively up to 100% over 20 years, without an immediate charge; unused allowance carries forward. The withdrawals are counted again when the bond ends: deferral, not exemption. The 5% withdrawal allowance. |
| Savings income rates, with no basic-rate credit | ITA 2007 s.18; ITTOIA 2005 s.530 (credit for UK policies only); HS321 | The gain is taxed as savings income at 20, 40 or 45% in 2026/27. From 6 April 2027 the rates are set to be 24, 44 and 49%: a two point rise already in Finance Act 2026, and a further two points announced in the Budget of 28 October 2026, which needs the Finance Bill to become law. There is no 20% credit, because the insurer paid no UK tax on the fund. Offshore bond tax calculator. |
| Top slicing relief and policy segments | ITTOIA 2005 ss.535 to 537; HS321 | The gain is divided by the number of complete years the policy has run to find a slice, and relief is given so that a gain built up over many years is not all taxed as if it were one year's income. Individuals only: trustees and companies do not get it. Surrendering whole segments, rather than drawing a large sum across every segment, avoids an artificial gain under the 5% rules. Top slicing relief explained. |
| Time apportionment relief | ITTOIA 2005 s.528; HS321 | The gain is reduced in proportion to the days you were not UK resident while you owned the policy, so a family that arrives, leaves or returns is taxed only on the UK share. Moving to or from the UK with a bond. |
| Personal portfolio bond rules | ITTOIA 2005 ss.515 to 526; IPTM3610 | Permitted investments are the insurer's internal funds, authorised and other collective funds, investment trusts, REITs and cash, or a manager the insurer appoints. If you, a connected person or someone acting for you can choose other assets, such as individual shares or a private company, the policy is a personal portfolio bond and a deemed gain of 15% a year is taxed whether or not anything is paid out. The personal portfolio bond rules. |
| Inheritance tax: long-term residence and trusts | IHTA 1984 s.6A, inserted by Finance Act 2025; gov.uk, trusts and inheritance tax | Since 6 April 2025 exposure to UK inheritance tax on non-UK assets follows long-term residence (UK resident in at least 10 of the previous 20 tax years), not domicile. A bond in your own name sits in the estate; any saving comes from the trust and gift rules, through a bare trust, a discretionary trust, a loan trust or a discounted gift trust. The long-term residence test and loan trusts and discounted gift trusts. |
Statutory references are to the Income Tax (Trading and Other Income) Act 2005 and the Inheritance Tax Act 1984 as in force for 2026/27. The 2027/28 rates are as announced; they take effect only when the Finance Bill is passed. This table is general information, not tax advice.
HMRC guidance, tribunal decisions and Budget measures that touch offshore bonds, trusts and inheritance tax. Every piece names the sources it starts from.
| Feature | Offshore investment bond (Isle of Man, Luxembourg, Ireland, Channel Islands) | UK onshore investment bond |
|---|---|---|
| Tax inside the fund | Gross roll-up: the insurer pays no tax on income and gains inside the policy in its home jurisdiction. Withholding tax at source on some foreign dividends is the only leak. | The UK life fund pays corporation tax on its income and gains at the policyholder rate, currently 20%, before anything reaches you. |
| Basic-rate credit on the gain | None. The whole gain is taxed at your savings rates, 20, 40 or 45% in 2026/27, after any savings allowance you have left. | A 20% credit for the tax the fund has paid: a basic-rate taxpayer owes nothing more, and higher and additional rate taxpayers pay the difference (ITTOIA 2005 s.530). |
| The 5% withdrawal allowance | Yes: 5% of each premium a policy year, cumulatively up to 100%. | Yes: 5% of each premium a policy year, cumulatively up to 100%. |
| Time apportionment relief | Yes, for days of non-UK residence while you owned the policy (ITTOIA 2005 s.528). | Yes, for policies issued or varied on or after 6 April 2013; the fund itself still paid UK tax while you were abroad. |
| Investment choice, within the personal portfolio bond rules | Wide: collective funds from many managers, investment trusts and mandates in several currencies, as long as the choice stays on the permitted list. | Usually the UK insurer's own fund range and the external funds it links to, in sterling. |
| If the insurer fails | Not covered by the Financial Services Compensation Scheme unless the policy is written through a UK branch. Isle of Man: a statutory scheme that can pay up to 90% of a protected contract. Guernsey: no scheme, but assets covering at least 90% of policyholder liabilities held in trust. Luxembourg: segregated custody and a first claim on the assets, the triangle of security. Ireland: the compensation fund excludes life policies. | The Financial Services Compensation Scheme pays 100% of a life insurance claim, with no upper limit, if the insurer is regulated by the Prudential Regulation Authority. |
The onshore and offshore wrappers are compared on a worked premium in onshore vs offshore bonds, and the protection regimes in if an offshore life insurer fails.
The Isle of Man and Luxembourg descriptions follow published summaries by local law firms and by Luxembourg for Finance, not the statutes themselves. What each regime pays, and to whom, is in if an offshore life insurer fails. The five are compared side by side on jurisdictions for UK residents.
