Offshore bond tax in the UK: one bill at the end instead of one every year

Held directly, a portfolio is taxed every year on its interest, its dividends and every gain the manager realises. Held inside an offshore life policy, nothing is taxed on you while the money stays invested: the whole return compounds, and tax falls due once, when you take the money out. Over 30 years on £5,000,000 that can be worth having. How much turns mainly on the rate you pay when the money comes out, and the figures below show the point at which it stops working.

The short version

Thirty tax bills, or one

Taxed as you go

Interest is taxed at 20, 40 or 45%. Dividends above the £500 allowance are taxed at 10.75, 35.75 or 39.35% from 6 April 2026. Every gain the manager realises above £3,000 a year is taxed at 18 or 24%. The tax leaves the portfolio each year, and only what is left compounds.

Taxed once, at the end

Income and gains inside the policy are not taxed on you each year. They are reinvested gross. Switching funds inside the policy is not a chargeable event. Tax arises only at a chargeable event: a full surrender, a withdrawal above the 5% allowance, an assignment for value, maturity, or the death that ends the policy.

The price

The gain is then income, not a capital gain: taxed at 20, 40 or 45% (47% on savings income from 6 April 2027), with no basic-rate credit because the insurer is outside the UK. Top-slicing relief can soften it. And the whole deferral depends on the policy holding only permitted investments.

Six moments that decide whether the policy pays

The figures are this page's hypothetical case: £5,000,000, 4% income and 3% growth a year, income taxed at a blended 42%, CGT at 24% on half the unrealised gains each year, a 0.60% policy charge, 30 years, and the exit gain taxed at 45% unless stated. In three of them the direct portfolio comes out ahead.

A mixed portfolio, cashed in after 30 years at 45%

Held directly

Year one alone costs £101,280 in income tax and CGT. Over 30 years about £7.4m of tax leaves the portfolio, and CGT on what is still unrealised takes £128,457 at the end. You keep about £19.5m.

Inside the policy

The policy grows untaxed to about £32.2m. Income tax at 45% on the £27.2m gain is about £12.2m, leaving about £19.9m: ahead by about £458,000. A thin margin, and it exists only because the period is long.

Every field can be changed. The model is deliberately simple so you can check it by hand: it holds one income yield, one growth rate and one set of tax rates for the whole period, and it prints its formula underneath. It is not a calculation of your own tax bill.

Held directly, after all tax

£19,475,776

After income tax on the income each year, CGT on the gains realised each year and CGT on the gains still unrealised when you sell in year 30.

Inside the policy, after tax on the gain

£19,934,042

The policy grows untaxed to £32,152,803. The gain of £27,152,803 is then taxed as income at 45%, on full surrender.

Policy value before tax on the gain	£32,152,803
Chargeable event gain	£27,152,803
Income tax on the gain	£12,218,761
Difference at the end, in favour of the policy	+£458,266
Tax paid in year one if held directly	£101,280
Income tax and CGT paid along the way if held directly	£7,390,157
CGT at the end if held directly	£128,457
Gain divided by years (the top-slicing slice)	£905,093 a year

On these numbers the policy is ahead by £458,266 after all tax. The slice of £905,093 a year is above the £125,140 additional rate threshold on its own, so top-slicing relief would not lower the rate much at this size.

The formula

Held directly, each year:
  income = value x income yield;  income tax = income x your income rate
  value = value + income - income tax + value x growth
  realised gain = unrealised gain x share realised;  CGT = (realised gain - £3,000) x CGT rate
  value = value - CGT  (the base cost rises by the realised gain and the reinvested income)
At the end, if you sell: CGT = (unrealised gain - £3,000) x CGT rate.  On death: no CGT.

Inside the policy:
  policy value = capital x (1 + income yield + growth - policy charge) ^ years
  gain = policy value - capital
  tax = gain x exit rate (or your own figure after top-slicing relief)
  after tax = policy value - tax

What the model leaves out, so you can judge it: the £500 dividend allowance and the personal savings allowance (worth a few hundred pounds a year at most to a higher or additional rate taxpayer), withholding tax deducted abroad on the underlying investments, losses, inflation, withdrawals, the 5% allowance, and inheritance tax. It treats the policy charge as a straight deduction from the return. It assumes the policy is not a personal portfolio bond.

Read the difference line first. With the defaults the policy is ahead by less than half a million pounds after 30 years, and behind at 20. Then move three inputs and watch the answer swing: raise the income yield (interest-heavy portfolios favour the policy most, because interest is taxed at 45% every year held directly), cut the share of gains realised (a buy and hold investor gains little from deferral and loses the 24% CGT rate), and lower the exit rate. Most of the planning goes into the exit rate: a policy is worth most to someone who expects to pay a lower rate when the money comes out than while it grows.

Your own figures

What the deferral is worth in your case

Send the portfolio's tax reports, the proposed policy charges and your expected route out: surrender, segments over several years, a move abroad, or holding until death. We will set out where the numbers fall.

How the policy is taxed: ITTOIA 2005 Part 4 Chapter 9

There is no special UK regime for private placement life insurance. A policy issued by an insurer outside the UK is a foreign life policy, taxed under the chargeable event rules.

You are liable if you are UK resident in the tax year the gain arises and you are beneficially entitled to the policy, or you created the trust that holds it, or it is held as security for your debt (ITTOIA 2005 s.465). Nothing is charged while the policy grows. A gain is calculated only on a chargeable event: surrender of all rights, assignment of all rights for money or money's worth, maturity, a death that gives rise to benefits, and the part surrenders and part assignments that exceed the allowance (s.484). Moving money between funds inside the policy is not on that list.

The gain is savings income (ITA 2007 s.18(4)), so in 2026/27 it is taxed at 20, 40 or 45% (gov.uk income tax rates). From 6 April 2027 savings income is taxed at 22, 42 and 47% (gov.uk policy paper; Finance Act 2026). It is not a capital gain: the 18 and 24% CGT rates and the £3,000 annual exempt amount do not apply. Scottish rates do not apply either, because Scottish taxpayers pay the UK rates on savings income (gov.uk Scottish income tax).

Why there is no 20% credit

A gain on a UK policy carries a non-repayable credit at the basic rate, because the UK insurer has already paid tax on its fund (IPTM3810). A foreign policy's gain has none: HMRC says gains on foreign policies "do not attract a non-repayable basic rate tax credit" (HS321; IPTM3720). An additional rate taxpayer therefore pays the full 45% on an offshore gain, against 25% on top of the credit for a UK bond. That missing credit is what gross roll-up costs. From 6 April 2027 the UK-policy credit follows the new savings basic rate of 22%.

What you pay when you cash in

On a full surrender the gain is broadly what you receive, plus anything taken out before, less the premiums paid and less gains already taxed. Top-slicing relief then divides the gain by the number of complete years the policy has run (IPTM3830) and asks what rate that slice would bear on top of your other income; if the slice falls partly below the higher or additional rate threshold, the tax on the whole gain is reduced (s.535). It is available to individuals only, not to trustees or personal representatives (IPTM3820). Its limit is size: a £27.2m gain over 30 years is a slice of about £905,000, well above the £125,140 point where the additional rate starts. How the gain is calculated and how the relief works, step by step, is in chargeable event gains and top-slicing relief.

Withdrawals of up to 5% of each premium a year, cumulatively up to 100% over 20 years, are not taxed when taken (s.507). They are only deferred, because they come back into the calculation of the final gain. The detail, including the trap of a large part surrender, is in the 5% withdrawal allowance.

How the same portfolio is taxed when you hold it directly

The comparison only means something if the direct side is taxed correctly. These are the 2026/27 figures for an individual in England, Wales or Northern Ireland.

Type of return	Basic rate	Higher rate	Additional rate	Tax-free amount
Interest	20%	40%	45%	Personal savings allowance £1,000, £500 or nil
Dividends	10.75%	35.75%	39.35%	£500 dividend allowance
Capital gains	18%	24%	24%	£3,000 annual exempt amount
Offshore bond gain	20%	40%	45%	Personal savings allowance; top-slicing relief; no CGT allowance

Sources: income tax rates, personal savings allowance, dividend rates from 6 April 2026, CGT rates and allowance. The dividend ordinary and upper rates rose by 2 points on 6 April 2026; the additional rate stayed at 39.35%. Savings rates rise to 22, 42 and 47% from 6 April 2027, which makes interest held directly more expensive and the exit from an offshore policy more expensive by the same amount.

The rates matter less than two features of the direct side. Capital gains are taxed only when you dispose of something, so a patient investor already controls the timing, and pays 24% rather than 45%. And there is no CGT charge when someone dies: assets pass to the personal representatives at their market value on the date of death (HS282). A directly held portfolio kept until death never pays CGT on its unrealised gains. A policy that ends on death produces a chargeable event gain taxed as income. That rule alone decides the fifth case above.

The condition behind all of it

Everything above assumes the policy is taxed under the ordinary chargeable event rules. Below are the three cases where that assumption fails or works differently.

Choosing your own investments

If you, a person connected with you, or anyone acting for you can select assets outside the permitted categories, the policy is a personal portfolio bond. A deemed gain of 15% of the premiums and earlier deemed gains is then taxed every year, whether or not the policy grew (s.516; IPTM3650). The deferral on this page disappears. What the policy may hold, and how to use a manager appointed by the insurer, is on the page on investment flexibility; the full rules are in the personal portfolio bond rules.

Trustees as policyholders

Where UK trustees are taxed on the gain because the settlor has died or is not UK resident, discretionary trustees pay 45% on it, with no top-slicing relief (gov.uk trusts and income tax; IPTM3820). A settlor who is alive and UK resident is taxed on gains in a trust they created (s.465).

Arriving in the UK

The four-year foreign income and gains regime for new residents does not cover chargeable event gains: they are not on the list of qualifying foreign income (RFIG45100). The relief for a new arrival is time apportionment, which removes the share of the gain that relates to days of non-residence (s.528). Moving to, returning to or leaving the UK with an offshore policy works through the numbers.

What the policy does not do

These hold whichever insurer or jurisdiction you choose.

It is not tax-free. It defers income tax and then charges it at up to 45%, or 47% on savings income from 6 April 2027, on a gain that may include growth which would have been taxed at 24% as a capital gain held directly.

It does not remove inheritance tax. A policy you own personally is part of your estate like any other investment. The inheritance tax result comes from the trust and the gift around the policy, covered on the page on inheritance tax and succession.

It is not protected by the FSCS (unless the policy is written through a PRA-authorised UK branch). The Financial Services Compensation Scheme covers life insurers regulated by the Prudential Regulation Authority; insurers in the Isle of Man, the Channel Islands, Ireland or Luxembourg are not (FSCS). What each home jurisdiction offers instead is in if an offshore life insurer fails.

It is not hidden. The insurer reports the policy under the Common Reporting Standard and issues chargeable event certificates, and you enter the gain on the SA106 foreign pages. See privacy and reporting.

It does not suit every portfolio. Low-income, low-turnover equity portfolios, short horizons and an estate that will be inherited rather than spent are the cases where holding directly usually wins. For a portfolio that throws off interest taxed at 45% every year, held for decades by someone who expects a lower rate or a different country at the end, the deferral is worth a good deal. For the costs side of the comparison, read PPLI costs and economics.

Offshore bond tax questions

Is an offshore bond tax-free in the UK?

No. Income and gains inside the policy are not taxed on you each year, but when a chargeable event happens (a full surrender, a withdrawal above the 5% allowance, an assignment for value, maturity or the death that ends the policy) the gain is taxed as savings income at 20, 40 or 45% in 2026/27, and at 22, 42 or 47% from 6 April 2027. The advantage is deferral and control of timing, not exemption.

How is the gain taxed when I cash in?

The chargeable event gain is savings income under ITTOIA 2005 Part 4 Chapter 9 and ITA 2007 s.18(4). It is added to your other income for the tax year and taxed at your marginal rate, with no basic-rate credit because the insurer is outside the UK. Top-slicing relief may reduce the tax if the gain divided by the years the policy has run would fall partly into a lower band. The insurer sends you a chargeable event certificate and you enter the gain on the SA106 foreign pages.

Why is there no 20% tax credit on an offshore bond when a UK bond has one?

A UK insurer pays tax on its policyholder fund, so a gain on a UK policy is treated as having borne basic-rate tax, which cannot be repaid. An offshore insurer is outside that system and its fund grows without UK tax, so HMRC gives no credit on the gain (HS321; IPTM3720). An additional rate taxpayer pays 45% on an offshore gain against a further 25% on a UK bond gain. From 6 April 2027 the UK-policy credit follows the savings basic rate of 22%.

Are the 5% withdrawals tax-free?

Not in the end. Each year you may withdraw up to 5% of each premium without an immediate charge, cumulatively up to 100% over 20 years (ITTOIA s.507). Those withdrawals are tax-deferred: they are added back when the final gain is calculated. Taking more than the cumulative allowance creates an immediate gain, which can be large relative to the money taken out.

Does top-slicing relief bring the rate down?

Sometimes. The gain is divided by the number of complete years the policy has run, and the relief asks whether that slice, added to your other income, would be taxed at a lower rate. It helps most when your other income is modest in the year you cash in and the slice is small. On a large policy the slice itself can exceed £125,140, so the relief does little. It is not available to trustees, personal representatives or companies.

Does capital gains tax apply to an offshore bond?

No. A chargeable event gain is charged to income tax, not CGT. The 18% and 24% CGT rates and the £3,000 annual exempt amount do not apply to it. That cuts both ways: growth that would have been a capital gain taxed at 24% held directly becomes income taxed at up to 45% inside the policy.

I am moving to the UK under the new FIG regime. Does it cover my bond?

It does not. The four-year foreign income and gains regime for new residents lists the types of qualifying foreign income, and chargeable event gains on life policies are not among them (RFIG45100). The relief that does apply is time apportionment under ITTOIA s.528, which reduces the gain by the share of days in the ownership period when you were not UK resident.

What happens to the tax if I die still holding the policy?

If your death ends the policy, it is a chargeable event. The gain is worked out on the surrender value immediately before death, so any extra life cover is excluded, and it is taxed as income. A directly held portfolio is different: there is no CGT on death and the assets pass at their market value on the date of death (HS282). Inheritance tax applies to both unless the policy sits in a suitable trust.
