Life insurance in trust: why your policy is probably adding to your inheritance tax bill — and how to fix it

The problem in numbers

You have a £500,000 life insurance policy. On your death, the insurer pays out within weeks. Your family receives £500,000. Problem solved?

Not quite.

If that policy is held in your name (the technical term is "in your estate"), the £500,000 payout is treated as part of your estate for Inheritance Tax purposes. If your total estate exceeds the nil-rate band — currently £325,000 for the 2026–27 tax year [1] — the excess is charged at 40%. In this scenario, your £500,000 policy triggers an extra £70,000 IHT bill that your family must pay before they can access the funds. They receive £430,000. The policy that was meant to protect them instead created a tax liability at the worst possible moment.

Now consider the same policy held "in trust." The payout goes directly to the trustees, who distribute it to your nominated beneficiaries. No IHT charge. No probate delay. Your family receives the full £500,000 within weeks of your death certificate being issued.

The difference: free paperwork and 30 minutes of your time at the outset.

This article explains what life insurance in trust means, why it works, and how to put an existing policy in trust today.

What happens to life insurance with no trust

The estate problem

When you own a life insurance policy in your personal name, the death benefit becomes part of your estate for IHT purposes. Section IHTM20012 of the HMRC Internal Tax Manual makes this clear: "Life policies and Inheritance Tax" [2] classifies the policy as a chargeable asset unless specifically exempted or held under trust.

This means:

• The full payout is added to your other assets (property, savings, investments, etc.)
• If the total exceeds £325,000 (the nil-rate band), the excess is charged at 40%
• Your executors must pay the tax bill before distributing the estate to beneficiaries
• The tax liability can force your family to sell assets to cover the bill, or wait months while probate processes

Probate delays

Probate is the legal process of proving your will and distributing your estate. It typically takes 4–12 months. During this time, life insurance proceeds held in your name are locked up. Your family may struggle with cash flow while they wait for the will to clear the court.

If the policy is held in trust, the trustees bypass probate entirely and pay out within weeks — often 4–6 weeks after your death certificate is issued [1].

Example: the real-world impact

Scenario	Policy in personal name	Policy in trust
Death benefit	£500,000	£500,000
Taxable estate (other assets)	£400,000	£400,000
Total estate value	£900,000	£400,000
Nil-rate band	£325,000	£325,000
Taxable amount	£575,000	£75,000
IHT at 40%	£230,000	£30,000
Family receives (after IHT)	£670,000	£870,000
Time to receive funds	4–12 months (via probate)	4–6 weeks

In this example, holding the policy in trust saves £200,000 in tax and gets the money to your family 8+ months faster.

What a life insurance trust does

How it works

A life insurance trust is a legal arrangement in which the policy is owned by trustees on behalf of your named beneficiaries, rather than by you personally.

On your death:

1. The trustees are notified
2. The insurer pays the benefit directly to the trustees
3. The trustees distribute the funds according to your wishes (typically set out in a "letter of wishes" — a non-binding guide that sits alongside the formal trust deed)
4. Your beneficiaries receive the money outside your estate, so it is not added to your taxable estate

Key point: The policy never forms part of your estate. IHT is calculated on your remaining assets only.

Why it is tax-free

The payout is tax-free because it falls outside your estate. HMRC's guidance on life policies held in trust (IHTM20154) confirms that a policy "settled on its own trusts" is treated as separate property, not as part of the deceased's personal estate.

This is not a loophole. It is a straightforward application of trust law and inheritance tax legislation. The policy is simply not part of your taxable estate.

The letter of wishes

The trust deed itself does not name beneficiaries. Instead, it gives the trustees discretion to distribute according to your letter of wishes — a private, flexible document that sets out your preferences.

A letter of wishes:

• Is not legally binding (the trustees may depart from it in exceptional circumstances)
• Can be changed at any time without telling anyone
• Remains private (it is not published like a will)
• Allows you to express intentions without the formality of a trust deed amendment

For many families, a discretionary trust with a clear letter of wishes provides the optimal balance of flexibility and tax efficiency.

Types of trust for life insurance

Bare trusts (absolute trusts)

In a bare trust, the beneficiary has absolute entitlement to the trust assets from age 18. The trustee is a nominee with no discretion.

When to use:

• You have one clear beneficiary (e.g., a spouse)
• You want to avoid all complexity
• The beneficiary is financially responsible and of age

Limitations:

• No flexibility if circumstances change (e.g., divorce, family estrangement)
• Assets are exposed to the beneficiary's creditors, divorce claims, or care-fee assessments
• Once created, it cannot be changed

Discretionary trusts

In a discretionary trust, no individual beneficiary has a right to the assets. The trustees have discretion about who receives what, guided by your letter of wishes.

When to use:

• You have multiple beneficiaries or want flexibility
• You want to protect assets from creditors, divorce, or care fees
• You want the trustees to respond to circumstances (e.g., if one beneficiary falls into financial hardship)
• You have a blended family or want to prevent inadvertent disinheritance

Advantages:

• Complete flexibility in distribution
• Asset protection for beneficiaries
• Trustees can adapt to changed circumstances
• Ideal for family situations where needs may shift

For most life insurance purposes, a discretionary trust is the better choice. [1] It provides asset protection, avoids probate, delivers tax efficiency, and gives trustees the flexibility to respond to real family circumstances.

Split trusts

If your policy includes both life and critical illness benefits, some insurers allow you to split the trust so that the life benefit goes to one set of beneficiaries and the critical illness benefit to another. This is uncommon but useful in blended-family situations.

The cost

Writing a life insurance policy in trust costs nothing. [1]

Whether you are taking out a new policy or writing an existing policy in trust, the insurer will:

• Provide the trust deed template for free
• Guide you through the process
• Arrange for you to execute the deed (typically witnessed, not notarised)

The entire process takes 30 minutes to an hour.

How to write an existing policy in trust

Step 1: Contact your insurer

Ring your insurance company and ask to write the policy in trust. Ask them to send you:

• The trust deed (template)
• A letter of wishes template (optional, but recommended)
• Guidance notes
• Instruction on who must sign and witness

Step 2: Decide on trustees

Name at least one (preferably two) trustees. Trustees must be:

• Adults (18+)
• Trusted to follow your wishes
• Ideally, not the sole beneficiary (to avoid the trust becoming pointless)

Common choices:

• Your spouse and an adult child
• A trusted friend and a family member
• A professional trustee (solicitor, accountant) — increasingly used for large estates

Important: The named insured (you, the policyholder) can be a trustee, but ideally should not be the sole trustee — this can blur the distinction between personal ownership and trust ownership and may trigger gift with reservation issues (see below).

Step 3: Complete the trust deed

The insurer's template will ask:

• Your full name and policy number
• The trustees' names and details
• How you want the benefit distributed (e.g., "all to my spouse, or if they predecease, to my children in equal shares")

You can also attach a letter of wishes that sets out your fuller intentions, including instructions for any critical illness benefit, nomination of guardians if beneficiaries are minors, or ethical instructions.

Step 4: Witness and sign

Sign the trust deed in front of witnesses (often two, depending on the insurer's requirements). Some insurers accept attestation (unsigned declaration) instead. Follow the insurer's guidance precisely.

Do not try to draft a trust deed yourself. Use the insurer's template. It is specifically written to satisfy IHT legislation and insurer requirements.

Step 5: Return to the insurer

Send the executed trust deed to the insurer. They will confirm receipt and update their records to show the policy is held in trust. This typically takes 2–4 weeks.

Once confirmed, the policy is no longer part of your estate for IHT purposes.

Retrospective trust — can you do it?

Yes. If you have an existing policy already in force, you can still put it in trust today. The process is identical: contact the insurer, complete their trust deed, sign, and return.

HMRC guidance (IHTM20242) addresses policies "gifted later" (i.e., policies originally issued in the policyholder's own name, then placed in trust subsequently). The tax treatment is the same — the gift is a potentially exempt transfer (PET) at the time of placement, but provided you survive seven years, no IHT is charged.

There is no downside to writing an existing policy in trust. Do it today if you have not already.

Putting life insurance in trust vs. gift with reservation

What is gift with reservation?

Gift with Reservation (GWR) is an anti-avoidance rule that was introduced in 1986 to prevent individuals from giving away assets but continuing to enjoy them. If a gift is made with a reservation of benefit, the gifted asset remains in the donor's estate for IHT purposes, defeating the point of the gift.

HMRC's guidance on gifts with reservation applied to life insurance is set out in sections IHTM14440 and IHTM14453 of the Internal Tax Manual [2].

Why life insurance in trust is usually not a GWR

When you place a life insurance policy in trust:

• You give up ownership of the policy
• The trustees own the policy
• You do not benefit from the payout (your beneficiaries do)
• You have paid premiums, but premiums are not a benefit from the policy in the GWR sense

The key question is: do you retain any benefit from the gifted property after the transfer? In a properly documented life insurance trust, the answer is no.

However, GWR can arise if:

• You continue to pay premiums and you are named as a trustee with discretion over distribution (in a discretionary trust), you may be treated as retaining a benefit
• You are both the sole trustee and a beneficiary of a discretionary trust (you could change the terms to benefit yourself)
• The trust is a sham — you continue to control it absolutely

To avoid GWR risk:

• Ensure at least one independent trustee (not just you)
• Document the arrangement properly (use the insurer's deed; do not draft it yourself)
• Do not treat the trust as personal property (e.g., continue to pay premiums from your personal account, do not expect to benefit)

For the vast majority of straightforward life insurance trusts, GWR is not a concern. The arrangement is a genuine transfer of ownership to trustees, and HMRC will treat it as such.

Discounted gift trusts and life insurance

A "discounted gift trust" is a specific strategy in which the donor sells a policy (or other asset) to a trust at a discounted price, retaining a life interest. This is a complex arrangement that intentionally involves GWR (to lock in the IHT value at the time of the gift).

This is not the same as a simple life insurance trust. A standard life insurance trust is a straightforward gift with no reservation. A discounted gift trust is an advanced technique that requires professional advice and is outside the scope of this article.

Pension nominations vs. trust nominations

The distinction

Many people confuse pension death benefits with life insurance death benefits. They are different.

Pension nominations:

When you nominate a beneficiary for your pension death benefits, you are making an "expression of wishes" — a direction to the pension scheme trustees about who should receive the proceeds. The scheme trustees are not bound by your nomination; they have absolute discretion. The benefit does not form part of your estate (it goes directly to the pension scheme trustees), so there is typically no IHT charge on the pension benefit itself.

Life insurance trust nominations:

When you place life insurance in trust, the policy is owned by the trust from the outset (or from the date of placement). The trustees are legally bound by the trust deed and your letter of wishes. The benefit is held in trust and distributed according to the deed.

Which is better?

For pensions, nominations are standard and appropriate — scheme rules require them, and there is no advantage to writing a pension policy in trust.

For life insurance, a trust is the better approach. It:

• Gives you more control over distribution
• Provides certainty (the trustees are bound by the deed, unlike pension scheme discretion)
• Bypasses probate
• Avoids IHT in most circumstances

Term insurance vs. whole of life in trust

Term insurance in trust

Term insurance (also called "term assurance") covers you for a fixed period (e.g., 20 or 30 years). If you die during the term, the insurer pays the benefit. If you outlive the term, the policy expires with no payout.

Why use term insurance in trust:

• Covers your family during your working years when they depend on your income
• If you die before the term expires, the benefit is paid to the trust outside your estate
• The benefit can be used to pay IHT on your other assets, or to replace lost income
• Cost-effective (term premiums are cheaper than whole-of-life)

Limitation: Once the term expires, there is no cover. This is fine if you expect your estate to reduce by then, or if your other assets will cover IHT by then.

Whole-of-life insurance in trust

Whole-of-life (sometimes called "whole life") insurance covers you until you die, whenever that is. The insurer always pays out. Premiums are higher than term, but the certainty of payout means it is a reliable IHT mitigation tool.

Why use whole-of-life in trust:

• Guaranteed payout whenever you die
• Ideal for covering a known, permanent IHT liability (e.g., a property you want to leave to charity, or an ongoing family business)
• Trust structure ensures the benefit avoids IHT itself, and can be used to pay the IHT bill on other assets
• Peace of mind (you know your family will receive the funds)

Limitation: Whole-of-life premiums are higher. You must be confident the policy will be in force until death (i.e., you must keep paying premiums).

Combined approach

Many families use both:

• Term insurance in trust for the working years (income replacement, mortgage cover)
• Whole-of-life insurance in trust for a smaller amount (to cover the estimated IHT bill on the main estate)

This balances cost, cover, and certainty.

Life insurance in trust as an IHT bridge

Life insurance in trust does not reduce your taxable estate — it does not use up any of your nil-rate band or reduce the value of assets passing to your beneficiaries. What it does is provide liquid funds to pay the IHT bill outside probate.

Think of it as a bridge:

• On one side: your estate, with assets (property, shares, business) that may be difficult to sell quickly or will trigger IHT
• On the other side: your beneficiaries, who need to pay the IHT bill quickly (typically within six months of death) to avoid interest
• In the middle: the life insurance trust, which provides immediate cash to pay the bill

How the bridge works in practice

Suppose you have:

• A house worth £800,000
• Savings of £100,000
• Life insurance in trust for £200,000
• Spouse to whom £325,000 transfers tax-free (nil-rate band)

On your death:

1. Your estate is valued at £900,000
2. Your spouse's nil-rate band covers £325,000
3. The remaining £575,000 is taxable at 40%, triggering a £230,000 IHT bill
4. But the life insurance benefit of £200,000 is paid directly to the trust, outside probate
5. The trustees use this to pay most of the IHT bill immediately
6. The remaining £30,000 can be paid from your savings
7. The executors can then deal with the property without the urgent pressure of the IHT bill

Without the trust, the executors would have to sell the house quickly to raise the £230,000, or wait for probate before releasing the insurance proceeds (which would be subject to IHT and locked in the estate).

With the trust, the bill is paid, and the house can be handled properly.

Using life insurance in conjunction with other planning

Life insurance in trust works best as part of a wider IHT strategy:

• Wills and trusts: A will structure that maximizes use of both spouses' nil-rate bands
• Gifting: Annual gifts, gifts on marriage, gifts to charity (to extend the nil-rate band)
• Lifetime trusts: Settlor-interested trusts to lock in current values and freeze IHT exposure
• Business relief and agricultural relief: If you have business or agricultural assets
• Spousal exemptions: Using your spouse's nil-rate band if they have no substantial assets of their own

Life insurance in trust is the "cash bridge" that makes these other strategies work.

Frequently asked questions

1. If I write my policy in trust, does the trustee own it?

Yes. Once the trust deed is executed, the trustees are the legal owners of the policy. You are no longer the policyholder in the eyes of the insurer, although you typically remain a trustee and continue to pay premiums. The distinction is important for IHT: the policy is not your property, so it does not form part of your estate.

2. If I put my policy in trust, do I have to tell the insurer every time the trustees change?

Yes, if the trustee is changed (e.g., if one trustee dies or steps down and is replaced). However, for discretionary trusts, beneficiary changes do not need to be notified to the insurer — only the trustees need to be aware. Check your insurer's requirements.

3. Can I still pay premiums if the policy is in trust?

Yes. The trustees own the policy, but in practice, you (as a trustee and the person who took out the policy) will typically pay the premiums from your personal account. This is normal and does not trigger IHT issues, provided the trust is genuine and not a sham.

Alternatively, the trust can hold assets (e.g., savings) and use them to pay premiums. This avoids any question about where the premiums are coming from.

4. What happens to the policy if I divorce?

This depends on whether the trust deed was drafted with flexibility in mind. A discretionary trust can be varied (usually by all the beneficiaries and trustees together) to reflect changed circumstances. If your ex-spouse is named as a beneficiary, the trustees can be asked to remove them.

If the trust is a bare trust (one sole beneficiary), it cannot be changed without the beneficiary's consent.

If you are divorcing, review your life insurance trust with a solicitor and consider whether the terms should be updated. Failure to do so could result in your ex-spouse receiving the proceeds.

5. Is there any time limit on when I can put a policy in trust?

No. You can put a policy in trust at any time — when you take it out, or years later. There is no time limit. However, if you place an existing policy in trust, the transfer is a potential exempt transfer (PET) — if you die within seven years of the transfer, there may be IHT to pay. This is uncommon in practice, but something to be aware of.

If you die more than seven years after placing the policy in trust, no IHT is due on the transfer itself.

6. Do I need a solicitor to put my policy in trust?

No. For a straightforward arrangement, the insurer's template trust deed is sufficient. You do not need a solicitor, although one can be helpful if your circumstances are complex (e.g., blended family, business ownership, significant estate).

The cost to a solicitor would typically be £200–500 for drawing up or reviewing a trust deed. For most people, this is unnecessary — the insurer's free template is adequate.

7. What is a "letter of wishes"?

A letter of wishes is a private, non-binding document in which you set out your hopes for how the trustees should distribute the benefit. It is not legally binding, but it provides the trustees with guidance and context.

A letter of wishes might say:

• "I hope you will pay the benefit to my spouse to cover the IHT bill"
• "If my spouse does not survive me, pay the benefit to my children in equal shares"
• "If any beneficiary is in financial hardship, prioritize them"
• "Use the benefit to pay my debts and funeral expenses first"

The trustees are not bound by a letter of wishes, but they will generally try to honor it unless circumstances make it impossible or unwise.

8. Is a life insurance trust just for rich people?

No. Any policy, large or small, benefits from being in trust. The advantages are:

• Avoidance of probate (faster payout)
• Avoidance of IHT (if the estate is above the nil-rate band)
• Clarity about distribution
• Asset protection

Even a £50,000 term insurance policy in trust is worth doing — it avoids probate delays and ensures the money goes where you want.

9. Does life insurance in trust count towards my nil-rate band or affect my annual gifting exemption?

If you are a trustee and the trust is discretionary, the premiums you pay are treated as gifts to the trust. These are potentially exempt transfers (PETs) in a discretionary trust (they are chargeable lifetime transfers, or CLTs, but will usually drop out of account after seven years).

If the trust is a bare trust, the premiums are PETs.

In practice, if premiums are modest (e.g., £500–2,000 per year), they will not materially affect your overall IHT position. Annual gifting exemptions (£3,000 per tax year) may cover some of the cost.

If premiums are substantial (e.g., £10,000+ per year), you should take advice about the IHT implications.

10. Can I change my mind after I put a policy in trust?

You can revoke (cancel) the trust, but this is complex and may have IHT implications. Once a policy is in trust, it is cleaner to leave it there.

If circumstances change (e.g., you marry, have children, or suspect family conflict), you can update the letter of wishes, or work with the trustees to vary the trust deed (with the agreement of all trustees and beneficiaries).

Do not put a policy in trust unless you are committed to the arrangement.

Disclaimer

This article is for educational purposes only and is not legal or tax advice. Life insurance trusts are legitimate tax planning tools authorized under UK law and HMRC guidance, but they must be properly documented and used genuinely.

The IHT treatment outlined in this article reflects the law as of April 2026, based on HMRC's Internal Tax Manual and relevant legislation. Tax law changes regularly; always verify current rules with a qualified accountant or tax adviser before taking action.

Every family's circumstances are different. Before placing a policy in trust, consider:

• Your overall estate plan
• The needs of your beneficiaries
• Whether a discretionary or bare trust is more appropriate
• Whether professional trustees should be appointed
• Whether other IHT mitigation strategies (lifetime gifting, business relief, spousal planning) would be more effective

If your estate is substantial, or if you have a blended family, complex business interests, or significant debts, consult a solicitor or accountant before implementing any trust structure. The cost of professional advice (typically £500–1,500) is negligible compared to the IHT savings and family harmony it can secure.
