Pilot trusts and inheritance tax now sit in an uneasy relationship: the structure still works legally, but two rule changes have stripped away most of the tax advantages that made pilot trusts popular. A pilot trust is a discretionary trust set up during your lifetime with a token amount, often £10, so the legal shell exists and can receive larger assets later, usually on your death. Once funded, it falls into the inheritance tax relevant property regime, where the nil rate band is £325,000 and the maximum periodic charge is 6% on value above that threshold.1GOV.UK. Inheritance Tax Nil-Rate Band and Residence Nil-Rate Band Thresholds From 6 April 2026 to 5 April 2028 Whether the structure still earns its keep depends on the size of the estate, what assets are going in, and when.
How the Trust Becomes an IHT Vehicle
A solicitor drafts the deed, names the trustees, identifies the potential beneficiaries, and sets out the trustees’ powers. The settlor transfers a nominal sum, and the trust legally exists. It then sits dormant, holding almost nothing, generating no income, and requiring almost no administration until a triggering event brings assets in.
That event is usually the settlor’s death. Assets can flow in through a will, a pension nomination, or a life insurance assignment without the delay of establishing a new trust under pressure. The settlor gets to shape distribution long before the wealth arrives, and trustees keep discretion to respond to circumstances the settlor could not have predicted. In exchange, everything that enters the trust becomes relevant property under Section 58 of the Inheritance Tax Act 1984: settled property in which no beneficiary holds a qualifying interest in possession.2legislation.gov.uk. Inheritance Tax Act 1984 – Section 58 From that moment, three distinct charges apply.
The Charges Once the Trust Is Funded
Entry Charges
Assets transferred into a discretionary trust during the settlor’s lifetime are chargeable lifetime transfers. Value above the settlor’s available nil rate band is taxed at 20%, half the death rate. The original £10 settlement sits far below the threshold and triggers nothing.
Bulk funding is where the real charge appears. If a will directs assets into the pilot trust on death, the transfer is taxed at 40% on amounts above the nil rate band, not 20%. If a lifetime transfer was made and the settlor dies within seven years, the 20% charge is recalculated at 40%, with credit for tax already paid. Taper relief can reduce the recalculated tax if death occurs between three and seven years after the transfer, but only on the amount exceeding the nil rate band.
Ten-Year Periodic Charges
Every ten years from the date the trust was created, HMRC charges inheritance tax on the value of the relevant property held at that anniversary. Section 64 establishes the charge.3legislation.gov.uk. Inheritance Tax Act 1984 – Section 64 Section 66 fixes the rate at three-tenths of the effective rate that would apply if the trust’s assets were treated as a hypothetical chargeable lifetime transfer.4legislation.gov.uk. Inheritance Tax Act 1984 – Section 66
The maximum lifetime rate is 20%, and three-tenths of that gives the 6% theoretical ceiling. In practice the charge is often lower because the first £325,000 of trust value is sheltered by the nil rate band, and the effective rate only climbs as the trust holds more above that threshold. Trustees must file a tax return at every ten-year anniversary, even when no tax is due.
Exit Charges
When capital leaves the trust, an exit charge applies under Section 65.5legislation.gov.uk. Inheritance Tax Act 1984 – Section 65 The rate is proportionate to the number of complete calendar quarters that have elapsed since the trust started or since the most recent ten-year anniversary, whichever is later. A distribution three years after the last anniversary would face a charge based on 12 of 40 quarters at the ten-year rate.
Exit charges do not apply to payments of trust expenses fairly attributable to the relevant property, or to payments that count as income for income tax purposes. Any capital distribution triggers the calculation, whether cash, property, or investments. Getting the timing or the proportionate rate wrong exposes trustees to interest and HMRC scrutiny.
The 2015 Rule That Killed the Multi-Trust Strategy
The original tax-planning appeal of pilot trusts for larger estates came from a quirk: before 2015, a settlor could create several pilot trusts on different days and fund them all later. Each trust was treated independently for periodic and exit charge calculations, and each got its own nil rate band. Five trusts on five different days effectively multiplied the tax-free allowance fivefold.
The Finance (No. 2) Act 2015 inserted Section 62A into the Inheritance Tax Act 1984 and closed the door.6legislation.gov.uk. Inheritance Tax Act 1984 – Section 62A Under the same-day addition rule, if the same settlor adds value to more than one trust on the same day, each trust’s periodic and exit charge calculations must factor in the value added to every other trust. The additions are included in the hypothetical transfer used to determine the tax rate, pushing the effective rate up and eliminating the benefit of splitting assets across structures.7GOV.UK. HMRC Internal Manual – IHTM42233 – The Settlement: Same Day Additions
The trigger is the day the assets are added, not the day the trust was created. If a settlor dies and their will pours assets into three pilot trusts set up years apart, all those assets arrive on the same day (the date of death), and the aggregation applies. The £325,000 nil rate band is effectively shared across the trusts rather than sitting in each one separately. Trustees who fail to identify other trusts caught by the rule end up underpaying and facing penalties.
Losing the Residence Nil Rate Band
The residence nil rate band adds up to £175,000 of inheritance tax-free allowance when a home passes to direct descendants on death, and transferability between spouses can lift that to £350,000 for a couple.1GOV.UK. Inheritance Tax Nil-Rate Band and Residence Nil-Rate Band Thresholds From 6 April 2026 to 5 April 2028 Discretionary trusts do not qualify. Because trustees, not a named beneficiary, decide who eventually receives what, the property is not treated as passing directly to descendants.
Section 144 offers a workaround. If trustees appoint the trust’s assets to qualifying beneficiaries (children or grandchildren) within two years of the settlor’s death, the appointment is read back as if those beneficiaries had inherited directly, and the RNRB becomes available. The catch is that the property must actually leave the trust and pass to the beneficiaries outright, which defeats the reason for using the trust in the first place. If long-term trustee control over the family home is the goal, the RNRB is effectively sacrificed.
For estates where the combined nil rate band (£325,000) and RNRB (£175,000) would shelter most of the value, up to £500,000 per person or £1 million for a married couple, directing a home into a pilot trust can raise the total tax bill compared with a straightforward inheritance. This is where pilot trusts most often trip people up.
Pension Death Benefits and the April 2027 Change
One of the most common uses of a pilot trust has been to receive pension death benefits. On death, remaining pension funds can be paid to the trust through a nomination or expression of wishes with the pension provider. Since the pension freedom reforms of April 2015, these lump-sum death benefits have generally been paid free of inheritance tax, because the pension fund sat outside the estate for IHT.
That treatment ends on 6 April 2027. Unused pension funds and death benefit lump sums will be brought within the deceased’s estate for inheritance tax purposes, aggregated with the rest of the estate, and potentially taxed at 40%. Pension death benefits flowing into a pilot trust will contribute to the IHT liability rather than bypassing it. The trust still works structurally: funds arrive outside probate, and trustees still control distribution. What disappears is the tax-free entry that drove much of this planning.
Once inside the trust, pension death benefits become relevant property and attract the periodic and exit charges above. Anyone with a pension nomination pointing at a pilot trust should review it with a financial adviser before April 2027.
Life Insurance Policies in Pilot Trusts
Assigning a life insurance policy to a pilot trust is one area where the structure still works cleanly. A policy written in trust from the outset, with trustees named as owners from day one, was never part of your estate, and no IHT applies on your death. The insurer pays the trustees directly, and they distribute according to the deed without waiting for probate.
Transferring a policy you already own personally into the trust later is different. That transfer is a chargeable lifetime transfer. If the policy has a surrender value, the amount above the available nil rate band is charged at 20%, and if you die within seven years the charge is recalculated at 40%. Getting the policy into trust at inception avoids the problem entirely.
The probate-avoidance benefit alone justifies the arrangement for many families. Probate can take months, and a payout landing with the trustees within weeks of the death certificate gives families access to cash when they need it. The funds are then subject to the relevant property regime’s periodic and exit charges for as long as they stay in trust.
Registration With HMRC
Since 2022, most UK express trusts must register with HMRC’s Trust Registration Service even without a tax liability. Pilot trusts get a narrow carve-out: if the trust was created before 6 October 2020 and holds less than £100, it qualifies as a Schedule 3A excluded trust and does not need to register unless it becomes liable for tax.8GOV.UK. Register a Trust as a Trustee Pilot trusts created on or after that date must register within 90 days regardless of how little they hold.
The exemption evaporates the moment the trust is funded. A pilot trust receiving pension death benefits or a life insurance payout will almost certainly trigger a tax liability, and trustees must register it and keep the register updated. Failure can attract a penalty of up to £5,000 per trust, though HMRC guidance indicates a first non-deliberate failure usually escapes penalty.8GOV.UK. Register a Trust as a Trustee Changes to trustees, beneficiaries, or assets must be updated within 90 days.
When a Pilot Trust Still Makes Sense
The same-day addition rule and the RNRB problem have narrowed the field, but not closed it. Estates well above the combined nil rate band and RNRB thresholds may be fully taxed regardless of structure, which makes the RNRB loss irrelevant. In those cases the trust’s flexibility can outweigh the periodic and exit charges: protecting assets from a beneficiary’s creditors, managing funds for young or vulnerable beneficiaries, and adapting to changed family circumstances.
The logistical advantage also survives. Having the trust already in existence when you die means assets flow in immediately, without the risk that a drafting error in the will invalidates a trust created by that will. It gives you the chance to discuss your wishes with the trustees while you are alive. For pension death benefits after April 2027, the trust still controls how and when funds reach beneficiaries even though the tax treatment changes.
The honest answer is to run the numbers before committing. A pilot trust that made sense in 2014, when multiple trusts could each shelter £325,000, may no longer justify the compliance costs after 2015. A trust designed around tax-free pension death benefits needs reassessing before April 2027. The structure is still sound; the tax landscape around it has shifted enough that professional advice on whether the benefits outweigh the charges is the only responsible way to proceed.
