Life Insurance in Trust and IHT: How Writing Your Policy in Trust Keeps the Payout Free of Inheritance Tax

A life insurance policy not in trust pays into the estate on death — subject to 40% IHT and months of probate delay. Writing the policy in trust takes the payout completely outside the estate: no IHT, no probate, funds reach the family within days. It is free, takes minutes, and is one of the most effective IHT planning steps available to anyone with life insurance.

Free and immediate: Most insurers provide a trust deed at no cost when a policy is taken out. Writing in trust does not affect the policy terms, premiums, or the insurer. There is no cost and no delay — it is simply filling in one additional form. If your life insurance is not in trust, contact your insurer today to arrange an assignment into trust.

Types of Life Insurance Trust

Bare trust

The simplest form of life insurance trust. The policy is held for named beneficiaries absolutely — each beneficiary has a fixed entitlement to their defined share. Payout goes directly to the named beneficiaries when the policy pays out. Advantages: simple to set up; no ongoing trustee decisions needed; payout is immediate and cannot be diverted. Disadvantages: the beneficiaries and their shares are fixed at outset and cannot be changed after the trust is set up. If a named beneficiary dies before the policyholder, their share falls back into the estate (unless alternative beneficiaries are named). Not ideal if family circumstances may change (new children, family members falling out).

Discretionary trust

The policy is held in a discretionary trust — a trust where the trustees have discretion over who receives the payout and how much. The policyholder specifies a class of potential beneficiaries (e.g. 'my spouse, children, and grandchildren') but the trustees decide the actual distribution. Advantages: maximum flexibility — the trustees can respond to family circumstances at the date of the payout (e.g. directing more to a child in financial difficulty, or to a surviving spouse rather than children). The class of beneficiaries can often be extended. Disadvantages: trustees must exercise discretion properly and account for all beneficiaries' interests; if no trustees can be found, there may be administration delays.

Flexible trust (survivor's discretionary trust)

A hybrid structure commonly used by insurers. The surviving spouse automatically receives the payout as a specified beneficiary — but the trustees have discretion over any residue or where the spouse does not survive. In practice, most insurer-provided trust deeds are flexible trusts with the spouse as the primary automatic beneficiary. Advantages: the surviving spouse gets the money quickly; if the spouse has already died, the trustees distribute to the remaining class. This is a practical default for most married couples where the main purpose is to protect the family if the breadwinner dies — the spouse needs the money immediately, without waiting for probate.

Key Facts About Life Insurance in Trust

What happens if life insurance is not in trust

If a life insurance policy is held in the policyholder's own name (not in trust), the payout on death is paid to the estate — it passes under the will or intestacy. The full payout is included in the estate for IHT at 40%. For example: a £500,000 life policy not in trust, with an estate already above the NRB, generates a further IHT charge of up to £200,000 (40% × £500,000). The payout also passes through probate, which means the beneficiaries may wait months before receiving the funds. If the purpose of the life insurance is to pay off a mortgage or provide immediate income for a surviving spouse, the delay through probate — and the reduction by 40% IHT — defeats the purpose entirely.

How writing in trust helps

When a life insurance policy is written in trust, the policy belongs to the trust — not to the policyholder personally. On the policyholder's death, the payout goes to the trustees (not to the estate) and is distributed directly to the beneficiaries. The payout is outside the estate — no IHT applies to it. It also bypasses probate — the insurer pays the trustees directly without waiting for a grant of representation. The beneficiaries can receive the funds within days of the claim being settled, rather than months after probate. For most families, this is the single most impactful, free, and simple IHT planning step available — most insurers provide trust deeds at no cost when a policy is taken out.

Is writing in trust a gift with reservation?

Writing a life insurance policy in trust is not a gift with reservation of benefit (GWR), provided the policyholder is not a beneficiary of the trust (or is only a discretionary — not automatic — beneficiary). If the policyholder is included as a potential discretionary beneficiary of the trust (which is common in discretionary trust deeds) alongside the spouse and children, HMRC accepts this does not create a GWR — the policyholder's interest is purely contingent and not a meaningful benefit. However, if the trust is structured so that the policyholder is the primary beneficiary (i.e. the policy pays back to the policyholder's estate if they survive), the GWR rules could apply. Specialist advice should be sought for more complex arrangements.

IHT treatment of the policy value during the policyholder's lifetime

During the policyholder's lifetime, a term life insurance policy (which pays out only on death) has a minimal value — typically its surrender value, which for a term policy is zero. A whole-of-life policy or an endowment has a surrender value that grows over time. For term policies written in trust: the policy is essentially worth nothing until death, so no meaningful IHT asset sits in the trust during the policyholder's lifetime — the IHT saving only crystallises at death. For whole-of-life policies: the growing surrender value is in the trust (not the estate) — giving a gradual IHT benefit even before death. The premiums paid are also outside the estate once paid into the trust — they do not return to the estate.

IHT treatment of premiums

The premiums paid on a life insurance policy in trust are gifts from the policyholder to the trust. In most cases, the premiums qualify as normal expenditure out of income under s21 IHTA 1984 — regular payments from income, forming a habitual pattern, with no effect on the policyholder's standard of living. If the s21 exemption applies, the premiums are fully exempt from IHT (no 7-year clock, no PET). If the premiums do not qualify as normal expenditure out of income (e.g. they are irregular or very large), they may be PETs or CLTs — though for most standard life insurance premiums (monthly or annual direct debit), the s21 exemption is typically available. Trustees should keep records of premium payments to support the s21 claim.

Frequently Asked Questions

Is writing a life insurance policy in trust free?

In most cases, yes — major UK insurance providers (Aviva, Legal & General, Royal London, Vitality, etc.) provide standard trust deeds at no cost when a policy is taken out. The trust deed is typically a one-page document completed alongside the insurance application. For existing policies not in trust, most insurers can arrange a retrospective assignment into trust — also usually free. Some complex or bespoke trust arrangements (e.g. offshore trusts or trusts for non-standard family structures) may involve legal fees. For the vast majority of individuals with standard family circumstances (spouse and children as beneficiaries), a standard insurer trust deed provides full IHT protection at no cost.

Can you add your life insurance policy to a trust after it has started?

Yes — an existing life insurance policy can be assigned into trust after the policy has started. The policyholder executes an assignment document (typically provided by the insurer) transferring the policy into the trust. The assignment is a gift of the policy to the trust. For a term insurance policy with no surrender value, the gift is of negligible value — no IHT arises. For a whole-of-life or endowment policy with an existing surrender value, the assignment is a gift of the surrender value — a PET (for a discretionary trust) or potentially a small CLT, depending on the trust structure. The assignment does not affect the policy terms or premiums — the insurer simply updates the policy ownership records.

What is a 'split trust' for life insurance and critical illness?

A split trust (sometimes called a dual trust or life and CI trust) is used where a policy covers both life insurance and critical illness. The critical illness benefit is kept in the policyholder's own name (not in trust) — so that if they are critically ill and make a claim, they receive the payout personally to pay for medical costs, adaptations, or income replacement. The life insurance element is placed in trust — so that on death, the payout goes outside the estate to the family. A single combined life and CI policy in trust would mean the critical illness payout goes to the trustees (and the policyholder would need to apply for a distribution) — which is why split trusts are used. Most insurers that offer both life insurance and critical illness in the same policy offer a split trust option.

Does the life insurance trust need to file trust tax returns?

A life insurance trust that holds only a term life insurance policy with no surrender value is typically not required to file trust tax returns during the policyholder's lifetime — a term policy generates no income or gains. Once the policy pays out and the funds are held in the trust before distribution to beneficiaries, there may be a brief period where the trust holds cash that generates interest — in which case a trust income tax return (SA900) may be required for that period. For most trusts, the payout is distributed to beneficiaries very quickly and no meaningful income arises in the trust. For whole-of-life or endowment policies in trust (with growing cash values), HMRC registration and annual trust returns may be required.

Who should be the trustees of a life insurance trust?

The trustees of a life insurance trust must be at least two individuals (or a trust company). The policyholder cannot be the sole trustee (otherwise the trust and the policyholder are effectively the same person). For most family arrangements: the trustees are the spouse or civil partner plus one or two other trusted individuals (adult children, a sibling, a close friend, or a solicitor). The trustees should be adults who can act impartially and in the beneficiaries' interests. The policyholder can be one of the trustees (as a co-trustee) — this is standard practice. Trustees should be updated when family circumstances change (e.g. if a named trustee moves abroad or loses capacity).

Can a life insurance policy in trust form part of a broader IHT plan?

Yes — a life insurance policy in trust is often used alongside other IHT planning as a 'funding' mechanism. For example: if a person makes PETs of significant value and dies within 7 years, the PETs become chargeable and the estate faces an IHT bill. A life insurance policy (written in trust so the payout is outside the estate) can be used to cover this IHT liability — providing funds to pay HMRC without forcing the family to sell assets. Similarly, a whole-of-life policy in trust can be used to provide funds to pay the IHT on the death estate — effectively pre-funding the IHT liability at a fraction of the cost (premium vs expected IHT charge), especially where the estate cannot be reduced significantly through other planning.
