Offshore bond vs ISA, GIA and pension: where each pound goes once the allowances are used
For most UK investors the order is, by convention, settled by the allowances: pension contributions up to the £60,000 annual allowance, then £20,000 a year into an ISA, and only then a choice between a general investment account and an offshore bond for what is left. The ISA is tax-free and small. The pension is tax-relieved, locked until 55 (57 from 2028), and from April 2027 inside the estate for inheritance tax. The GIA pays tax every year as income and gains arise, at 18% or 24% on gains and up to 39.35% on dividends, but gets a capital gains uplift on death. The offshore bond pays nothing until a chargeable event, lets you draw 5% a year, can be given away in segments or put in trust, and taxes the whole gain as income at up to 45%, rising to 47% from April 2027, with no uplift on death. Which of the last two wins depends on what is in the portfolio, how long it is held, and who is holding it when the tax falls due.
The question we are asked most often by UK families is not whether an offshore bond is a good idea in the abstract but where it sits next to the wrappers they already have. This page sets the four side by side on the 2026/27 rules, says plainly what each is good at, and then deals with the only comparison that is close, the bond against the general investment account. The numbers are the enacted ones; the tax drag calculator linked at the end does the arithmetic for your own portfolio.

The four wrappers in one table
| Feature | ISA | Pension | General investment account | Offshore bond |
|---|---|---|---|---|
| How much can go in | £20,000 a year, frozen to April 2031 | £60,000 annual allowance, tapered for high earners | No limit | No limit |
| Tax on the way in | None, from taxed income | Relief at your marginal rate | None, from taxed income | None, from taxed income |
| Tax while invested | None | None | Income tax on dividends and interest each year; CGT on each disposal | None in the UK; withholding tax on some foreign dividends |
| Tax on the way out | None | 25% tax-free up to £268,275; the rest as income | Already paid as you go | Income tax on the gain at 20/40/45% (22/42/47% from April 2027), with top slicing relief |
| Access | Any time | From 55 (57 from April 2028) | Any time | Any time; 5% a year with no immediate tax |
| Can it be given away? | No, cash only | No | Yes, but a gift is a CGT disposal | Yes, segments by deed, no income tax on the gift |
| On death | In the estate; spouse can inherit the allowance | In the estate from 6 April 2027 | In the estate; CGT base cost uplifted | In the estate unless in trust; gain taxed as income, no uplift |
The ISA: first, and finite
Nothing beats an ISA for the £20,000 it can take each year. No income tax, no capital gains tax, no reporting, and the whole amount available at any time. The overall limit is frozen at £20,000 until 5 April 2031. One change is coming: regulations laid before Parliament on 14 September 2026 cap cash ISA subscriptions at £12,000 for savers under 65 from 6 April 2027, inside the same £20,000, and stop under-65s moving money from a stocks and shares ISA into a cash ISA (HMRC policy paper; Tax-free savings newsletter 23). Interest on cash held inside a stocks and shares ISA will be charged at the savings basic rate. None of that touches the invested ISA, which remains the first place for money a family can afford to lock into equities. For inheritance tax an ISA is in the estate like any other asset; a surviving spouse can add the deceased's ISA value to their own allowance.
The limitation is size. £20,000 a year, or £40,000 for a couple, is small against a large portfolio, and ISAs cannot be given to children or put into trust without first cashing them in.
The pension: relieved, locked, and now in the estate
The annual allowance is £60,000. It tapers by £1 for every £2 of adjusted income above £260,000, once threshold income exceeds £200,000, down to a floor of £10,000 at adjusted income of £360,000 (gov.uk pension scheme rates). Contributions attract relief at the saver's marginal rate, growth is untaxed, and up to £268,275 can be taken tax-free, with the balance taxed as income when drawn. Nothing can be drawn before 55, rising to 57 in April 2028. For high earners the taper means the pension often takes much less than £60,000 a year, and for anyone above the lump sum allowance the tax-free element is already used.
The change that has altered the planning is inheritance tax. From 6 April 2027 unused pension funds and death benefits form part of the estate for deaths on or after that date, with personal representatives liable for the tax and the spouse and charity exemptions preserved (HMRC policy paper; Finance Act 2026 ss.66 to 71). A pension left untouched for the next generation, which was the standard advice for a decade, now carries 40% inheritance tax on the fund and income tax in the beneficiary's hands if the member dies after 75. Our page on pensions and inheritance tax from April 2027 works through what that does to the order of drawdown. The pension is still the right place for contributions up to the allowance; it is no longer the right place to leave money that was never going to be spent.
The general investment account: simple, and taxed every year
A GIA is a portfolio held in your own name with no wrapper at all. Dividends are taxed at 10.75%, 35.75% or 39.35% above a £500 allowance. Interest is taxed at 20%, 40% or 45% above the personal savings allowance of £1,000, £500 or nil, with the £5,000 starting rate for those with little other income. Gains are taxed at 18% within the basic rate band and 24% above it, after an annual exempt amount of £3,000 (gov.uk CGT rates). Every dividend, coupon and sale goes on the return in the year it happens. From 6 April 2027 the savings rates rise to 22%, 42% and 47%.
What the GIA has going for it is the capital gains rate, and death. Growth is taxed at 24% at most, against up to 45% income tax on a bond gain, and on death the base cost of every holding is uplifted to market value with no capital gains tax at all (TCGA 1992 s.62). A long-held, low-turnover, low-yield portfolio in a GIA that passes on death is hard to beat. What counts against it is everything that pays income: the dividend and interest tax is paid every year out of the portfolio, which is the drag the calculator at the end measures, and a manager who trades crystallises 24% as she goes.
The offshore bond: deferred, movable, and taxed as income
Inside an offshore bond nothing is taxed in the UK until a chargeable event. Up to 5% of each premium can be withdrawn each year for twenty years with no immediate tax and no entry on the return (our page on the 5% allowance). Segments can be given to adult children or a spouse or placed in trust without a chargeable event, and the recipient is then taxed at their own rates with top slicing over the full life of the policy (assigning an offshore bond). A manager can trade inside the bond without any tax consequence.
The gain is savings income, taxed at 20%, 40% or 45% rather than at the capital gains rates, and 22%, 42% or 47% from April 2027. The whole gain, not the top-sliced amount, counts towards adjusted net income, so a large gain can wipe out the personal allowance for that year. And on the death of the last life assured the gain is taxed as the deceased's income with no uplift, which is why a bond meant to be passed on is written on younger lives or as a capital redemption bond. On the other side of the ledger, a bond gain is savings income, so someone with little other income can set the personal allowance, the £5,000 starting rate and the personal savings allowance against it: up to £18,570 of gain at nil in 2026/27 for a person with no other income, which is how segments given to a non-earning spouse or an adult child at university come out tax-free. Our page on how an offshore bond is taxed in the UK covers the rules in full, and the comparison with a UK insurer's bond is on onshore vs offshore bonds.
Bond against GIA: the comparison that is actually close
Strip out the ISA and the pension, which are filled first, and the choice for the rest of the money is between a GIA and a bond. It depends on the five factors in the table.
| Factor | Favours the GIA | Favours the offshore bond |
|---|---|---|
| What the portfolio produces | Capital growth with little income; gains taxed at 24% at most | Dividends, interest, hedge fund or private credit distributions, which a GIA taxes every year at up to 39.35% or 45% |
| How it is managed | Buy and hold, few disposals | Active management, fund switches, rebalancing, each of which is a CGT disposal in a GIA |
| Who pays the tax at the end | The same additional rate taxpayer, on growth, at 24% | A lower rate family member, a non-resident, or the investor in a year of low income, after top slicing |
| What happens on death | Held to death by the investor: CGT uplift wipes the gain | Given away in segments or held in trust during life, or written as a capital redemption bond |
| Time horizon | Short; the bond's deferral has not had time to compound | Long; gross roll-up on income that would otherwise be taxed yearly |
The arithmetic that decides it is the annual drag. A GIA with a 3% yield taxed at 39.35% loses about 1.2% of its value to tax every year before any growth is counted; the same portfolio in a bond loses nothing until the end. Over twenty years that gap compounds, and whether it outweighs the difference between 24% and 45% on the final gain depends on the yield, the growth and who takes the gain; insurers' published break-even examples are illustrations, not rules. The reverse tends to hold for a portfolio yielding 1% and growing 6%, where the GIA's 24% capital gains rate and the uplift on death are hard to overcome. The GIA vs offshore bond calculator runs the comparison on your own yield, growth, rate and horizon, and the break-even calculator adds the bond's charges to see whether the tax saving covers them.
From 6 April 2027 the bond's income tax cost rises by two points at each rate while the GIA's capital gains rates stay where they are, which tilts the growth-heavy case a little further towards the GIA and leaves the interest-heavy case where it was, since the GIA's rates on interest rise by the same two points; dividend rates do not change, so a dividend-heavy portfolio also tilts a little towards the GIA.
A sensible order, and what it is not
Advisers usually fill wrappers in this order: employer and personal pension contributions up to the allowance, then the ISA, then the bond or GIA for the remainder, with the GIA's annual exempt amount and dividend allowance used each year before anything else is taxed. That is convention rather than law, and it bends. A family that has already lost its personal allowance to the taper, is above the pension lump sum allowance, and expects the next generation to be basic rate taxpayers or to live abroad will put proportionately more into the bond. A family of buy-and-hold equity investors who intend to pass the portfolio on death will put more into the GIA. The decision for the money above the allowances deserves to be made rather than left to default.
Questions about ISAs, pensions, GIAs and bonds
Should I use an ISA before an offshore bond?
Yes, almost always. The ISA is tax-free on income, gains and withdrawals, and the £20,000 annual limit is small enough that filling it costs nothing in flexibility. The bond is for the money that does not fit in the ISA or the pension.
Is an offshore bond better than a general investment account?
It depends on the portfolio and on who takes the gain. The bond wins where the portfolio produces income that a GIA would tax every year, where the manager trades often, or where the gain will be taken by someone paying a lower rate. The GIA wins for a low-yield, low-turnover portfolio held until death, when the capital gains uplift removes the tax altogether. Our tax drag calculator runs your own figures.
Is an offshore bond better than a pension?
Not for contributions within the annual allowance, where relief at the saver's marginal rate on the way in is hard to beat. The bond is for money above the allowance, for high earners whose allowance is tapered to £10,000, and, since the April 2027 inheritance tax change, for money that was going to be left in a pension to pass on rather than spent.
Can a bond gain use the personal savings allowance?
Yes. A chargeable event gain is savings income, so the personal allowance, the £5,000 starting rate for savings and the personal savings allowance can all be set against it if other income leaves room. Someone with no other income can take up to £18,570 of gain at nil in 2026/27. The onshore bond credit cannot be repaid, so this helps most with an offshore bond.
What is changing for cash ISAs?
From 6 April 2027 cash ISA subscriptions are capped at £12,000 for savers under 65, within the unchanged £20,000 overall limit, under regulations laid before Parliament on 14 September 2026. Under-65s will not be able to transfer from a stocks and shares ISA into a cash ISA. The stocks and shares ISA limit is unaffected.
Is an offshore bond taxed on death?
Yes, if the death is that of the last life assured: the gain to the date of death is taxed as the deceased's income for that year, and there is no capital gains uplift. The policy value is also in the estate for inheritance tax unless held in trust. A capital redemption bond, which has no life assured, is not ended by the owner's death.
Does a bond gain reduce my personal allowance?
It can. The whole gain counts towards adjusted net income in the year of the event, so a gain that takes income above £100,000 tapers the personal allowance and above £125,140 removes it. Top slicing relief restores the allowance in the relief calculation but not in the main one, which is one reason to spread surrenders across tax years.
