A UK Pilot Trust Funded With Pension Death Benefits, for a US Beneficiary
A UK bypass or pilot trust holding pension death benefits is a foreign non-grantor trust from day one. What that costs a US beneficiary.
A UK bypass or pilot trust holding pension death benefits is a foreign non-grantor trust from day one. What that costs a US beneficiary.
When a UK pension scheme pays a lump sum death benefit into a discretionary trust and one of the beneficiaries is a US person, two tax systems take hold of the same money and want opposite things from it. On the UK side the position is well charted: where the member had reached age 75, the scheme administrator deducts tax before the trustees receive anything, and the trust then sits inside the relevant property regime. On the US side the trust is a foreign non-grantor trust from the day it is funded — and the accumulation that makes the structure work for inheritance tax is precisely what builds a future tax charge for the US beneficiary.
Almost everything written about spousal bypass trusts and pilot trusts is written for a wholly British family. This article covers the same UK ground, then adds the half that is missing.
Death benefits from a money purchase pension are normally payable at the discretion of the scheme administrator or the scheme trustees. The member signs an expression of wish; the scheme decides. That discretion is the reason the pot has historically sat outside the member's estate, and it is also why a nomination binds nobody.
A pilot trust is a discretionary trust created during life with a nominal sum, waiting to receive something much larger later. A spousal bypass trust is the same idea aimed at a specific outcome: the death benefit goes to trustees rather than to the surviving spouse, so it never joins the survivor's own estate, while the survivor can still be a beneficiary. Two points matter before anything else:
The modern case for the structure is control rather than tax: who benefits, when, and what happens on a remarriage, a divorce or a care assessment. That is a reasonable objective. It is also the objective that collides hardest with the US rules.
Where a registered pension scheme pays a lump sum death benefit to a non-qualifying person in respect of a member who had reached age 75 at the date of death, the special lump sum death benefits charge applies. Section 206 of the Finance Act 2004 sets the rate at 45% and makes the scheme administrator the person liable, whether or not the administrator or the recipient is UK resident. HMRC's Pensions Tax Manual puts it flatly: "The rate of the special lump sum death benefits charge is 45%."
A non-qualifying person is defined in section 206(9) as someone who is not an individual, or an individual receiving the payment as a trustee, personal representative, company director, partner or member of an LLP. A bare trustee is carved out by section 206(10). So the charge turns on the capacity of the recipient, not on the size of the payment and not on the tax position of the people who will eventually benefit. The money simply arrives reduced.
That has a consequence worth stating plainly: the US beneficiary's own circumstances make no difference to the UK deduction. Where the trustees later appoint funds to an individual, UK practice treats the deducted tax as available to set against that person's own liability — confirm the mechanics with the trustees and the scheme administrator rather than assuming them, because the route differs by scheme.
Until recently, death benefits following the death of a member under 75 could become taxable simply because they were paid or designated more than two years after the scheme administrator learned of the death. That trap has been removed. HMRC's Pension schemes newsletter 186 states that "This two-year rule will be removed," so that benefits "will not become taxable solely because a payment is made or funds are designated after the end of the two-year period", and instructs administrators to stop deducting tax on that basis for payments made on or after Budget day, 28 October 2026.
Two cautions. The change was announced at Budget 2026 and is to be legislated through the Finance Bill — HMRC is applying it administratively, so it is not yet settled law. And the newsletter says nothing about trusts, non-qualifying persons or the special charge, so nobody should assume it switches off a 45% deduction in a particular case. Ask the administrator what it intends to do before the payment is made, not after.
This is where the published guidance runs out. Run the standard US classification sequence and the answer arrives quickly. The arrangement is a trust. It is a foreign trust, because a UK settlement will not satisfy both the court test and the control test. And it is a non-grantor trust: the person whose pension it was is dead and was never a US-taxable grantor, and the funding comes from a third party — the scheme administrator exercising its own discretion — rather than from anyone the US would treat as an owner.
So there is no "grantor status flip" of the kind that dominates the literature on offshore family trusts. The classification is settled on the day the lump sum lands. The same logic applies to a trust arising under a will, which we set out in detail in our article on UK will trusts and US beneficiaries.
What follows is the ordinary foreign non-grantor trust machinery. The trust is a separate taxpayer for US purposes. A distribution in a year carries out that year's distributable net income to the recipient. Anything distributed above it is an accumulation distribution, traced back against income the trust accumulated in earlier years, taxed under the throwback rules and carrying an interest charge for the period of deferral. The beneficiary reports distributions on Form 3520; Form 3520-A is the trust-level return that arises where there is a US owner, which here there generally is not.
Hold the two logics side by side. The inheritance tax case for a bypass or pilot trust is to accumulate: keep value out of the survivor's estate, let it sit, appoint it later to the right people at the right moment. The US throwback regime is built to punish exactly that: income left in a foreign trust and handed over years later is worse, not better, than income handed over as it arises.
A trust designed to be left alone is therefore the worst possible shape for a US beneficiary — and because the trustees hold the discretion, the beneficiary cannot fix it unilaterally. Two further points deserve care:
Once the lump sum is in the trust it is relevant property, and the discretionary trust regime applies. On each ten-year anniversary a principal charge arises on value above the settlement's available nil-rate band, which stands at £325,000. The rate is computed rather than flat, and it cannot exceed 6% — three tenths of the 20% lifetime rate. HMRC states it directly: "The rate may be anything up to 6%." When capital leaves the trust between anniversaries, a proportionate exit charge arises, counted in fortieths for each complete quarter since the last anniversary. We walk through the mechanics in our piece on the ten-year anniversary charge where a beneficiary is a US person.
One practical point that trips people up: the date the trust's ten-year cycle starts is not always obvious for a pension-funded settlement, and practitioners describe different dates depending on whether the scheme is trust-based or contract-based. Settle that question with the scheme and the trust deed in hand rather than assuming the date of the payment.
HMRC's technical note on inheritance tax and pensions confirms that most unused pension funds and death benefits will be brought within the value of a deceased person's estate from 6 April 2027. The note is specific about what sits outside: death in service benefits, a qualifying dependant's scheme pension, and a dependant's or nominee's annuity purchased together with the member's own lifetime annuity. It is equally specific that the change bites on deaths, not payments — "If the pension scheme member dies before 6 April 2027, then the current rules will apply," even where the benefit is paid afterwards.
On exemptions, the note describes them as applying to certain beneficiaries "such as transfers between spouses and civil partners, where they are long-term UK residents". That qualifier is omitted by almost every secondary summary and it matters a great deal where the surviving spouse lives in the United States. The note does not discuss bypass trusts or discretionary trusts by name at all, so whether an exemption can be claimed where the recipient is trustees rather than the spouse is a live question for a professional to answer on your facts — not something to take from a blog, ours included.
Cross-border trust positions are not a place for a single-country view. Our US-UK private client tax practice works the UK and US analyses together, and every position and filing is reviewed and signed by a licensed professional — a CPA or Enrolled Agent in the United States and an ACCA-qualified accountant in the United Kingdom. If a death benefit decision is in front of you now, book a consultation before the nomination or the appointment is made, because almost none of these choices can be unwound. If the pension itself has already been inherited outright, start instead with inheriting a UK pension as a US person.
