Whole-of-Life Insurance in Trust: How It Cuts an Inheritance Tax Bill (2026/27)
How writing a whole-of-life insurance policy in trust removes the payout from your estate, why it matters for Inheritance Tax in 2026/27, and how the numbers stack up.
The problem: a life policy paying straight into your estate
Most people take out life insurance to protect their family financially after their death, without considering what happens to the payout for Inheritance Tax purposes. If a policy simply names your estate (or your executors) as the recipient, the payout is added to the value of everything else you own — property, savings, investments — when working out your total estate value for IHT.
Given the current Nil Rate Band of £325,000 and Residence Nil Rate Band of up to £175,000 (both frozen until April 2030), a life insurance payout of, say, £250,000 can easily push a moderate estate over the combined £500,000 threshold, resulting in a 40% tax charge on the amount above it — including potentially 40% of the insurance payout itself.

Putting a life insurance policy "in trust" means legally separating the ownership of the future payout from your personal estate at the point the policy is set up (or at any later point, using an insurer's standard deed). On death:
- The payout goes directly to the trustees, who then distribute it to the beneficiaries named or covered by the trust.
- Because the money never legally belonged to your estate, it is not counted when calculating your estate's value for Inheritance Tax.
- It also bypasses probate, meaning trustees can usually release funds to beneficiaries far more quickly than assets held in the estate, which typically must wait for a grant of probate before being distributed.
Worked example
Consider an individual with an estate worth £600,000 in other assets (property, savings, investments), plus a £200,000 whole-of-life policy.
Without the policy in trust:
- Total estate for IHT: £600,000 + £200,000 = £800,000
- Available Nil Rate Band + Residence Nil Rate Band (assuming full entitlement to both): £325,000 + £175,000 = £500,000
- Taxable estate: £800,000 − £500,000 = £300,000
- IHT at 40%: £120,000
With the policy written in trust:
- Total estate for IHT: £600,000 only (the £200,000 payout bypasses the estate)
- Taxable estate: £600,000 − £500,000 = £100,000
- IHT at 40%: £40,000
The trust arrangement saves £80,000 in this example — the full 40% tax that would otherwise have applied to the £200,000 payout.
Choosing the right trust type
- Bare trust: Simple and fast to set up, names specific beneficiaries who are entitled to the money as soon as it is paid out. Less flexible if circumstances change (new children, changed relationships), since beneficiaries are fixed.
- Discretionary trust: Gives trustees discretion to decide, from a wider class of potential beneficiaries, who ultimately benefits and in what proportions. More flexible for changing family circumstances, but can in rare cases (typically very large sums assured) attract the "relevant property" regime's periodic and exit charges.
- Split trust: Combines critical illness or income protection cover (which stays with the policyholder, since they may need it themselves) with the life cover element (which is held in trust for beneficiaries) — common where a policy bundles both types of protection.
Using the payout to fund an IHT bill on other assets
A frequently overlooked benefit is that trust funds, once released to trustees on death, are not tied up in the same probate delay as the rest of the estate. Since HMRC generally expects Inheritance Tax to be paid (or at least substantially paid) before probate is granted and other assets can be released, having a trust-held life policy payout available provides a practical source of funds to cover that bill without beneficiaries needing to raise a loan or sell assets under time pressure.
A word of caution on large policies
For very large sums assured combined with other chargeable lifetime transfers, discretionary trusts can in principle be subject to a 10-yearly periodic charge and exit charges on distributions, under the same "relevant property" regime that applies to other discretionary trusts. This is a specialist area — anyone considering a very large whole-of-life policy in trust as part of a broader estate plan should take independent regulated financial advice rather than relying on a standard template alone.

Why does writing a life insurance policy in trust matter for Inheritance Tax?
A life insurance payout that goes directly to your estate on death is normally counted as part of your estate's value for Inheritance Tax purposes. Writing the policy in trust means the payout goes straight to the trust beneficiaries instead, bypassing your estate entirely and avoiding a 40% IHT charge on that payout.
Does putting a policy in trust cost anything?
Setting up a trust for a life policy is usually free or low-cost when using a standard trust deed provided by the insurer, though more complex or bespoke trust arrangements drafted by a solicitor can carry legal fees. There is no ongoing cost to the trust itself beyond occasional administration.
Can I still change the beneficiaries after putting a policy in trust?
It depends on the type of trust. A discretionary trust gives trustees flexibility to choose which of a defined class of beneficiaries eventually receives the payout, offering more flexibility than a fixed/bare trust, which names specific beneficiaries who cannot easily be changed once set up.
Is a whole-of-life policy in trust itself subject to any tax?
The policy proceeds paid to a trust are generally free of Inheritance Tax in the policyholder's estate, but the trust itself can be subject to periodic and exit charges under the 'relevant property' trust regime if the payout, combined with other chargeable transfers, exceeds the settlor's available Nil Rate Band at the relevant assessment points, most commonly relevant for very large sums assured.
How quickly is the payout available to beneficiaries?
Because the payout does not form part of the probate estate, funds held in trust can typically be released to beneficiaries much faster than assets tied up in probate, which is one of the most valued practical benefits — providing funds when they may be needed urgently, such as to cover an IHT bill on other assets before probate is granted.
Does a whole-of-life policy in trust help pay an IHT bill on the rest of my estate?
Yes, this is one of its most common uses. Trustees can be instructed (informally or via a formal loan arrangement) to make funds available quickly to help beneficiaries pay an Inheritance Tax bill on other assets, since IHT is generally due before probate is granted and other assets released.
Is whole-of-life insurance more expensive than term life insurance?
Yes, generally significantly more expensive, because whole-of-life policies are guaranteed to pay out eventually (since death is certain), whereas term policies only pay out if death occurs within a fixed term and many term policies never claim, which keeps premiums lower.
Can a couple use a joint whole-of-life policy in trust for IHT planning?
Yes. A common structure is a 'joint life second death' policy, which pays out only on the second death of a couple — timed to coincide with when an IHT bill on the combined estate typically becomes due, and often cheaper in combined premium terms than two single-life policies.
Does writing a policy in trust affect who can claim the payout if I am divorced or separated?
Potentially, yes. Trust beneficiary nominations do not automatically update on divorce or separation the way some other arrangements might, so it is important to review and if necessary formally change trust beneficiaries after a significant change in personal circumstances.
Do I need a solicitor to put a life insurance policy in trust?
Not necessarily. Most insurers provide standard trust deed templates (bare, discretionary or split trusts) that can be completed without a solicitor for straightforward cases. More complex family situations, blended families, or very large sums assured often benefit from bespoke legal drafting.
