The personal portfolio bond rules: why a bespoke PPLI portfolio fails for UK residents

Why the rules exist

An offshore life policy defers tax. Income and gains inside it are not taxed on the policyholder each year; tax falls due only at a chargeable event. Without a limit, anyone could put their own portfolio into a policy wrapper, keep running it as before, and postpone tax on it for decades. The personal portfolio bond rules, in ITTOIA 2005 ss.515 to 526, are that limit. HMRC describes them as anti-avoidance provisions “aimed at preventing the placement of personal assets within the chargeable event regime to benefit from postponement of tax” (IPTM3600).

The rules were introduced by the Personal Portfolio Bonds (Tax) Regulations 1999 (SI 1999/1029), made on 30 March 1999 and in force from 6 April 1999, and were rewritten into ITTOIA in 2005. Policies taken out before 17 March 1998 have separate transitional rules (IPTM3620).

The definition: who can select

Under s.516 a life policy, life annuity or capital redemption policy is a personal portfolio bond if two conditions are met.

• Condition A: some or all of the benefits are determined by reference to the value of property of any description, or to fluctuations in an index. Every unit-linked offshore bond meets this.
• Condition B: the terms of the policy permit the property or index to be selected by any of the following: the holder; a person connected with the holder; the holder and a connected person together; a person acting on behalf of the holder; or a person acting on behalf of a connected person.

The test looks at what the terms permit and at who in practice has a say. HMRC reads it widely. Where the insurer has complete discretion there is no personal portfolio bond, “however, if the policyholder has influence over the selection then the 'ability to select' lies with the policyholder” (IPTM7715). The same paragraph makes three further points: an option to select that you never exercise still counts; where there are several policyholders, it is enough that one of them can select; and if you later select property outside the permitted categories despite the original terms, HMRC will treat the terms as having been varied, so the policy becomes a personal portfolio bond from then.

The way out: permitted property and indices

A policy is not a personal portfolio bond if all the property that can be selected falls within the categories in s.520 and meets the selection conditions in s.521, or if any index that can be selected is one allowed by ss.518 and 519 (s.517).

Sources: s.520(2); IPTM3640. The Treasury can amend the list by regulations (s.520(5) to (7)). The permitted indices, described in IPTM3630, are the retail prices index, similar general price indices published by foreign governments, and published indices of the prices of shares listed on a recognised stock exchange.

Several familiar holdings are absent. There is no category for shares in a single listed company picked for you, for unquoted company shares, for land and buildings held directly, for a loan to a family company, or for an interest in a private fund that is not a collective investment scheme in the sense HMRC describes. If the policy lets you select any of those, it is a personal portfolio bond. Whether a particular private markets vehicle fits category 3 or 7 depends on its legal form and should be checked, not assumed.

The selection conditions in s.521

Being on the list is not enough on its own. The opportunity to select must also be offered on the right terms. HMRC restates the two conditions in s.521 as follows (IPTM3640):

• The general condition: property meets it “if, at the time when it may be selected, the opportunity to select property falling within the same category is available to all policyholders of the insurer, or persons acting on behalf of those policyholders”.
• The class condition: property meets it “if, at the time when it may be selected, the opportunity to select property falling within the same category is available to a particular class or classes of policyholders of the insurer or persons acting on behalf of the members of that class or those classes”.

HMRC's reading of availability is strict. The policyholder “should only be able to select property or an index for linking that is available for selection at that time by all policyholders”, applied class by class. Objective limits, such as a minimum investment, are acceptable. But “If a policyholder had any say in the limiting conditions, set either by the manager of the investment or the insurer, that would make the policy a PPB” (IPTM7780). A fund range built around one family's wishes fails that test however conventional its contents.

The 1999 regulations as made went further for classes, requiring them to be clearly identified in marketing or other promotional literature as available generally and not limited to connected persons (SI 1999/1029, reg 4(8)). For indices, HMRC's current guidance still describes a class condition that excludes connected persons and relies on criteria set by the insurer and disclosed in its marketing (IPTM3630). An insurer's documents should show how any class is defined and published.

HMRC's guidance on who is really choosing

Most cases in practice turn on the role of a manager or adviser. HMRC's manual deals with the common arrangements one by one.

The broker-managed fund deserves a precise reading, because it is the route most often misunderstood. The adviser can be one you chose and already know. What keeps the policy outside the rules is not who the adviser is, but that after the policy is taken out the adviser manages an insurer fund as the insurer's agent, the fund is open to the broker's other clients, and you cannot select its assets. HMRC then adds the warning that governs all of these cases: “The terms of the legislation cannot be avoided simply by interposing an investment adviser or broker between the policyholder and the insurer” (IPTM7730). The same paragraph says the insurer need only examine the contracts it is party to. A side understanding between you and your adviser about what to buy is outside what the insurer checks, and the tax consequence falls on you.

The 15% deemed gain

If a policy is a personal portfolio bond, a gain is treated as arising at the end of each insurance year except the final one (s.522; IPTM3650). HS321 gives the formula as 15% of (A + B minus C), where:

• A is the total premiums paid up to the end of the year;
• B is the total of the deemed gains in earlier years;
• C is the total of earlier part-surrender gains.

The charge bites hard. It is a chargeable event gain (s.525) taxed as savings income although no cash leaves the policy, so the tax is paid from money held elsewhere. It compounds, because each year's deemed gain joins B. There is no basic-rate credit on an offshore policy. And there is no top-slicing relief on these deemed gains: the statute ignores personal portfolio bond events for the relief (ITTOIA 2005 s.535(6)), and HMRC's manual says the number of complete years entered on the return should be 1 so that in practice no relief is given (IPTM3830). Insurers' technical guidance, including M&G's, says the same.

The deemed gains are not lost. When the policy ends, the final gain is calculated in the normal way, less any earlier policy gains (s.491; IPTM3500), and that includes the deemed gains. If the investments did very well, part of the charge amounted to tax paid early. At ordinary rates of return the deemed gains run far ahead of the real growth, and the negative final figure can be used only through deficiency relief. Because ITTOIA 2005 s.541 leaves personal portfolio bond deemed gains out of the previous gains that deficiency relief is measured against, relief for that negative figure may be nil, and in any case deficiency relief “will not reduce the amount of tax due on income liable at the additional rate” (IPTM3880).

Worked example: £5,000,000 over ten years at 45%

Hypothetical. A UK-resident additional rate taxpayer pays a single premium of £5,000,000 into a policy that lets his own manager buy individual shares on his instructions. The investments grow by 5% a year. He takes no withdrawals and surrenders at the end of year 10. The tax rate is held at 45% for illustration; savings income is taxed at 47% for additional rate taxpayers from 6 April 2027, which would make every figure in the tax columns higher.

Amounts are rounded to the pound; the arithmetic was checked by script. The investments made £3,144,473 over ten years. The deemed gains came to £12,589,381, four times the real profit, and £5,665,222 of tax was paid on them from outside the policy. Because ITTOIA 2005 s.541 leaves personal portfolio bond deemed gains out of the previous gains that deficiency relief is measured against, relief for the negative final figure of £9,444,908 may be nil, and in any case it gives nothing against the 45% charged on this holder's income.

The same £5,000,000 in a policy holding permitted funds, with the same 5% growth, would pay no tax for ten years and then 45% on the real gain of £3,144,473 at surrender: £1,415,013 before any top-slicing relief. The £4,250,209 difference is what the ability to choose costs, and it explains why a US-style or continental-style bespoke mandate does not travel to a UK-resident policyholder. The calculator on the page on investment flexibility reruns this table with your own premium, term, rate and growth.

What a UK resident can do instead

The rules close off one kind of policy. They leave open a wide range of investments and three ways of running them.

1. Choose from the insurer's general list. Authorised funds, overseas collective investment schemes, investment trusts and REITs across most asset classes, offered to all the insurer's policyholders or to a defined class. Switching between them inside the policy is not a chargeable event; see switching funds, managers or insurer.
2. Use the insurer's internal linked funds. You pick the fund or the risk level; the insurer or its appointed manager picks the assets (IPTM7720).
3. Use a manager who acts for the insurer. Either an adviser the insurer appoints, often from a panel, or a broker-managed fund run by an adviser you know but open to the broker's other clients (IPTM7725). The mandate must leave real choice to the manager, and you must not direct individual purchases or sales (IPTM7730).

What does not fit is the family company, the London flat, the concentrated position in a single share and the private fund picked for you. Those are better held directly, in a family investment company or in a trust, with their own tax treatment, and kept out of the policy. For families arriving in the UK with an existing policy that allows free selection, the time to restructure is before the first policy anniversary as a UK resident; see moving to, returning to or leaving the UK.

Why the US and continental model differs

Private placement life insurance grew up in markets with different tests. In the United States the policy's separate account must meet diversification requirements (26 USC 817(h)), and the IRS's investor control doctrine asks whether the policyholder directs the particular investments. Continental insurers, in Luxembourg and elsewhere, commonly offer a dedicated internal fund for one policyholder, run by a manager the client proposes, under rules set by their own regulators. In those systems a bespoke mandate is normal, and the question is whether the client has crossed a line into direct control.

The UK test starts from the other end, with the policy terms. Do they allow the policyholder, a connected person or anyone acting for them to select property outside a fixed list, and is each choice open to all policyholders or to an objectively defined class? Who runs the day-to-day trading is beside the point. A fund dedicated to one family, whose rules reflect that family's wishes, fails that test even if an independent manager runs it well. A policy designed for a US or continental client can therefore be unobjectionable at home and a personal portfolio bond in the hands of a UK resident. How the UK wrapper compares overall is set out on the page on PPLI for UK residents, and the tax on a compliant policy's gain is in chargeable event gains and top-slicing relief.
