Writing life insurance in trust: how it avoids inheritance tax and probate delays

How a life payout is taxed if not in trust

If a life insurance policy is not written in trust, the payout on death is paid into the deceased's estate. This means it is counted as an asset for inheritance tax purposes and can push the total estate value above the tax-free thresholds, triggering a 40 percent charge on the excess.

For the 2025-26 tax year, the inheritance tax nil-rate band stands at £325,000, a figure frozen until 5 April 2030. An additional residence nil-rate band of £175,000 applies where a home is passed to direct descendants, such as children or grandchildren. These bands are transferable between spouses and civil partners, meaning a surviving partner can potentially use any unused portion of the deceased partner's allowance.

When a payout forms part of the estate, the executor must include it in the inheritance tax account. Tax is due on the value above the combined thresholds at a rate of 40 percent. HMRC reported inheritance tax receipts of around £8.2 billion in 2024-25, a record figure according to HMRC statistics, reflecting the impact of frozen thresholds on estates that include property, savings and insurance payouts.

The payout is also subject to the probate process. The executor cannot distribute funds to beneficiaries until a grant of probate is issued, which requires the inheritance tax position to be settled first. This can delay access to the money for several months, during which time mortgage payments or other family expenses may still be due.

What writing in trust does

Writing a life insurance policy in trust transfers legal ownership of the policy to named trustees. The payout is then paid to the trustees, who hold it for the benefit of the beneficiaries you choose. Because the policy no longer belongs to you, it falls outside your estate for inheritance tax purposes.

The key effect is that the payout is not counted when calculating inheritance tax. This means the full sum assured can be paid to your family without a 40 percent deduction, provided the trust is set up correctly and no other estate assets exceed the available thresholds.

Another significant benefit is speed. Since the payout does not form part of the estate, it does not need to wait for a grant of probate. HMCTS reports that probate applications can take several weeks or months to process, depending on the complexity of the estate. A trust payout can be released as soon as the insurer receives the claim and the trustees provide the necessary documentation, often within a matter of days or weeks.

The trustees have a legal duty to manage the funds according to the trust deed and your stated wishes. They can pay out immediately to adult beneficiaries or hold funds for minors until they reach a specified age. This structure gives you control over how and when the money is distributed, rather than leaving it to the default rules of intestacy or the probate process.

Types of trust for life policies

Several trust structures are available for life insurance policies, each with different rules about who benefits and when. The choice depends on your family circumstances, the ages of beneficiaries and whether you want flexibility to change beneficiaries in the future.

An absolute trust, also known as a bare trust, names specific beneficiaries who have an immediate right to the policy and its proceeds. Once the trust is created, you cannot change the beneficiaries. The payout must be paid to them directly when the policy pays out, which can be useful for straightforward situations where you want certainty about who receives the money.

A discretionary trust gives trustees the power to decide which beneficiaries receive payouts and in what proportions. You can name a wide class of potential beneficiaries, such as your spouse, children and grandchildren, and leave a letter of wishes to guide the trustees. This offers flexibility if circumstances change, such as a divorce or the birth of new children, but it requires trustees to exercise judgment.

A flexible trust, sometimes called a power of appointment trust, combines elements of both. It allows you to appoint beneficiaries at the outset but retains the ability to change that appointment later within a defined period. This can be useful if you are unsure about future family arrangements.

For critical illness cover, a split trust is often used. This separates the critical illness benefit from the life cover, so the critical illness payout can be paid directly to you while the life cover remains in trust for your beneficiaries. Without this split, the critical illness benefit might be tied up in the trust and inaccessible to you during your lifetime.

Who to appoint as trustees and beneficiaries

Trustees hold legal title to the policy and are responsible for managing the payout according to the trust terms. In practice, you should appoint at least two trustees to ensure continuity and to avoid a single individual having sole control over significant funds.

Common choices for trustees include a spouse or civil partner, adult children, a trusted friend, or a professional such as a solicitor or accountant. You should consider whether the trustees are likely to be available and capable of acting when the policy pays out, which may be many years in the future. It is also wise to appoint a successor trustee in case one of the original trustees dies or becomes unable to act.

Beneficiaries are the people who will receive the payout. You can name your spouse or partner, children, grandchildren or any other individual. If you have minor children, the trust can hold funds until they reach a specified age, such as 18 or 21, rather than paying out to a guardian who may not manage the money as you intended.

For vulnerable beneficiaries, such as those with disabilities or mental health conditions, a discretionary trust can be particularly useful. It allows trustees to manage funds on their behalf, protecting them from financial exploitation and ensuring the money is used for their benefit over time. You should also write a letter of wishes to accompany the trust deed, setting out how you would like the trustees to exercise their discretion, although this letter is not legally binding.

Pitfalls

Several common mistakes can undermine the benefits of writing a life policy in trust. Joint life first death policies, mortgage cover assigned to a lender, and existing policies all require careful consideration before placing them in trust.

A joint life first death policy pays out on the first death of two insured individuals. If this policy is written in trust, the payout on the first death passes to the trust, but the surviving partner loses the life cover. This can leave the survivor without protection, particularly if the policy was intended to cover a mortgage or provide ongoing income. A joint life second death policy, which pays on the second death, is often more suitable for inheritance tax planning, but the trust terms must match the policy type.

Mortgage decreasing term cover is often assigned to the lender as security for the loan. If the policy is assigned, the lender has a legal interest in the payout, which can complicate a trust arrangement. You may need to remove the assignment or restructure the policy before placing it in trust, and you should check whether the lender requires a specific beneficiary clause.

Large discretionary trusts can trigger periodic charges. The relevant property regime imposes a charge on the value of the trust every ten years, and an exit charge may apply when funds are distributed. For most life policies, the value at the ten-year point is the policy's surrender value, which is often low, but this should be reviewed with a professional if the policy is large.

Placing an existing policy in trust is not a straightforward inheritance tax avoidance measure. If you have owned the policy for some time, the transfer into trust may be treated as a gift for inheritance tax purposes. If you die within seven years of making the transfer, the value of the policy may still be counted in your estate under the seven-year rule, although taper relief can reduce the tax due.

How to set it up and what it costs

Setting up a life insurance trust is usually straightforward and often free if you use the insurer's own trust form. For more complex family situations, a solicitor can draft a custom trust deed, which will incur legal fees but provides greater flexibility.

Most life insurance providers offer standard trust forms that you can complete when you take out a new policy or when you want to place an existing policy in trust. These forms are designed to be simple and typically cover absolute and discretionary trusts. You complete the form, name your trustees and beneficiaries, and return it to the insurer. The insurer will then note the trust on the policy records, and there is usually no charge for this service.

If your circumstances are more complex, such as a blended family, a business interest or a need for a flexible trust, you may choose to instruct a solicitor. A solicitor can draft a trust deed tailored to your requirements, which might include provisions for changing beneficiaries, protecting assets from divorce or managing funds for vulnerable individuals. Legal fees vary depending on the complexity of the trust and the solicitor's charging structure, but they are typically a one-off cost rather than an ongoing expense.

Once the trust is established, you may need to register it with HMRC's Trust Registration Service. Since 2020, most UK trusts must be registered unless they are specifically exempt. The registration is free and must be completed within 90 days of the trust being created or becoming liable for UK taxes. The trustees are responsible for registration, and they must also keep the trust's details up to date, including any changes to beneficiaries or trustees.

Is a life insurance payout subject to inheritance tax?

Yes, if the policy is not written in trust. The payout forms part of your estate and is counted towards the inheritance tax thresholds of £325,000 and £175,000. Any amount above these thresholds is taxed at 40 percent.

What does writing a life insurance policy in trust mean?

It means transferring legal ownership of the policy to named trustees. The payout is then paid to the trustees for the benefit of your chosen beneficiaries, and it falls outside your estate for inheritance tax purposes, avoiding probate delays.

Which type of trust should be used for life insurance?

The choice depends on your circumstances. An absolute trust gives immediate rights to named beneficiaries, while a discretionary trust allows trustees to decide who benefits. A flexible trust offers a balance, and a split trust is used for critical illness cover to keep the illness benefit accessible to you.

Can I put an existing life insurance policy in trust?

Yes, you can usually place an existing policy in trust using the insurer's trust form, often at no cost. However, the transfer may be treated as a gift for inheritance tax purposes, and the seven-year rule could apply if you die within seven years of the transfer.

Does a life insurance trust need to be registered with HMRC?

Most UK trusts must be registered with HMRC's Trust Registration Service unless they are exempt. Registration is free and must be completed within 90 days of the trust being created. The trustees are responsible for registration and for keeping the trust details up to date.

Frequently asked questions

Is a life insurance payout subject to inheritance tax?

A life insurance payout forms part of your estate for inheritance tax (IHT) purposes if the policy is not written in trust. If your estate exceeds the nil-rate band of £325,000, the excess is taxed at 40%. Writing the policy in trust removes the payout from your estate, so it is not subject to IHT.

What does writing a life insurance policy in trust mean?

Writing a life insurance policy in trust means you legally assign the policy to trustees who hold it for named beneficiaries. On your death, the payout is paid directly to the trustees and then to the beneficiaries, bypassing probate. This can speed up payment and avoid inheritance tax, as the payout is not part of your estate.

Which type of trust should be used for life insurance?

For life insurance, an absolute (bare) trust is often used because it gives beneficiaries a fixed right to the payout. A discretionary trust offers flexibility in deciding who benefits and when, but may have tax implications. A split trust can keep critical illness cover for the policyholder while placing life cover in trust. Seek professional advice.

Can I put an existing life insurance policy in trust?

Yes, you can normally put an existing life insurance policy in trust by completing a trust form provided by your insurer. This is usually free. For joint life policies, both policyholders must agree, and the trust may be structured differently. Check with your insurer for specific terms and conditions.

Does a life insurance trust need to be registered with HMRC?

Most life insurance trusts do not need to be registered with HMRC unless they are subject to income tax or capital gains tax. Since 2020, only trusts with a tax liability must register. An absolute trust for life insurance typically has no tax liability, so registration is not required. However, a discretionary trust may need registration if it incurs taxes.
