Putting Life Insurance in Trust for Inheritance Tax

The short answer

If you write your life insurance policy in trust, the payout does not form part of your estate when you die. That means it is not subject to inheritance tax (IHT), and it is paid directly to the people you have chosen — without waiting for probate. For a typical family, this one piece of paperwork can keep a six-figure payout out of reach of a 40% tax charge and put cash in your loved ones' hands within weeks rather than months.

It is one of the simplest, cheapest and most effective estate-planning steps available in England and Wales. Most insurers provide a trust form free of charge, yet a large proportion of policyholders never complete it. This guide explains why it matters, how it works, and what to watch out for.

Why a policy outside trust gets taxed

When you take out life insurance and do nothing else, the policy is owned by you. On your death the proceeds are paid into your estate. If the total value of your estate — home, savings, investments and that insurance payout — exceeds your available allowances, the excess is taxed at 40%.

Each person has a nil-rate band of £325,000, frozen until April 2030, plus potentially a residence nil-rate band of up to £175,000 where a home passes to direct descendants. A life insurance payout sitting inside the estate can easily be the very sum that pushes you over those thresholds. Imagine a £200,000 policy landing on top of an estate that has already used its allowances: that payout could attract £80,000 of inheritance tax. Written in trust, the same £200,000 passes entirely tax-free. For more on the thresholds, see our Nil-Rate Band Explained guide and the broader Inheritance Tax UK: Complete Guide.

How writing a policy in trust works

A trust is a legal arrangement where you (the settlor) place an asset — here, the life policy — under the control of trustees, who hold it for the benefit of your chosen beneficiaries. If you are unfamiliar with the concept, our What is a Trust? UK Guide sets out the basics.

Because the policy is held in trust rather than owned by you personally, the proceeds never legally belong to your estate. When you die, the payout goes to the trustees, who distribute it to the beneficiaries according to your wishes. The money simply bypasses your estate — and therefore the IHT calculation — altogether.

Crucially, putting a protection policy in trust does not usually create a tax bill for you while you are alive. A standard term life policy has no real cash value, so there is nothing meaningful to "give away". The premiums you pay are typically modest and very often fall within the gifts out of surplus income exemption — regular gifts from surplus income that do not reduce your standard of living — making them immediately exempt from IHT.

Faster payment without probate

The tax saving gets the headlines, but the speed advantage is just as valuable in practice. When a policy pays into your estate, the insurer normally needs to see a grant of probate before releasing the money. Probate can take many weeks or months, during which your family may struggle to cover the mortgage, funeral costs or day-to-day bills.

A policy in trust sidesteps this entirely. The trustees only need to provide a death certificate and complete the insurer's claim form. Funds are typically released far more quickly — often within a couple of weeks — giving your beneficiaries cash exactly when they need it most. This is the same principle that makes trusts useful elsewhere in estate planning; you can read more in How to Reduce Inheritance Tax.

Which type of trust to use

Insurers generally offer two main types of trust for life policies:

• Absolute (bare) trust. You name fixed beneficiaries who cannot be changed later, and each beneficiary's share is set from the outset. It is simple and certain, but inflexible — if your circumstances change, you cannot redirect the benefit. See Bare Trusts Explained.
• Discretionary trust. You name a class of potential beneficiaries (for example "my children and grandchildren") and give the trustees discretion over who receives what, guided by a letter of wishes. This is far more flexible and copes well with changing families, but the trust is "relevant property", which can in principle attract a 20% entry charge on amounts above the nil-rate band, a periodic charge of up to 6% every ten years, and exit charges. In practice, because life policies usually have little or no value during your lifetime, these charges rarely bite. Our Discretionary Trusts Explained guide covers this in detail.

Most insurers' standard trust wordings are well drafted for the purpose, but the choice between absolute and discretionary genuinely matters. If you want maximum flexibility — and most people do — the discretionary route is usually preferred. For wider context on choosing structures, see Family Trusts Explained.

How to put your policy in trust

The process is refreshingly straightforward:

• Ask your insurer for their trust form. Almost every UK life insurer provides one free of charge. You can complete it when you apply for cover, or at any time afterwards for an existing policy.
• Choose your trustees. You are normally a trustee during your lifetime, alongside at least one other person you trust. Appoint at least two so there is always someone able to act.
• Choose your beneficiaries. Either name them outright (absolute trust) or define a class and add a letter of wishes (discretionary trust).
• Sign and date the form, with witnesses. Return it to the insurer and keep a copy with your important papers.

Tell your trustees the policy and trust exist and where to find the paperwork — a trust no one knows about helps no one. For the mechanics of trusts more generally, see How to Set Up a Trust in the UK and Trustee Duties and Responsibilities.

Things to watch out for

It is a powerful tool, but a few points deserve care:

• Joint life policies. Many couples hold a joint, first-death policy paying out to the survivor. Transfers between spouses and civil partners are already IHT-exempt, so a trust may add little on the first death; the tax issue usually arises on the second. Single-life or second-death cover is often the better candidate for a trust.
• Existing policies with value. Writing a whole-of-life policy that has a surrender value into trust is a gift, so the seven-year rule can apply to that value. For term policies this is rarely a concern.
• Trust registration. Many trusts must be registered with HMRC's Trust Registration Service. Some pure-protection policies in trust can be exempt while no benefit has been paid out — but check, as the rules are detailed.
• Pensions are different. Death-in-service and pension death benefits are usually dealt with through scheme nomination forms, not policy trusts — and the IHT treatment of pensions is changing from 2027. See Pensions and IHT from 2027.

When to take professional advice

For a straightforward term policy, completing the insurer's free trust form is low-risk and almost always worthwhile. Where things are more complex — a whole-of-life policy with significant value, large premiums, a blended family, business cover, or an estate already over the £2 million taper threshold for the residence nil-rate band — it is worth speaking to a qualified estate planner before you sign. The right trust, with the right beneficiaries and an up-to-date letter of wishes, ensures the payout does exactly what you intend. A qualified estate planner can review your existing cover, confirm whether a trust is needed, and make sure it dovetails with the rest of your inheritance tax planning.
