A life insurance trust is a legal arrangement that lets you ring‑fence your policy’s payout so it doesn’t become part of your estate. In the UK, this simple step can save your beneficiaries tens of thousands of pounds in Inheritance Tax (IHT) – often the difference between a full payout and a 40% tax bill.
Many people buy life insurance specifically to cover a future IHT liability, but if the policy is written in trust, the proceeds are paid directly to your chosen beneficiaries, bypassing your estate entirely. That means no IHT on the payout, and your loved ones get the money much faster.
The Inheritance Tax Problem in the UK
Inheritance Tax is charged at 40% on the value of your estate above the nil‑rate band – currently £325,000 (2024/25). If you own a home, that threshold can rise to £500,000 with the residence nil‑rate band, but many estates still exceed it.
Without a trust, a life insurance payout is added to your estate for IHT purposes. So the very policy you bought to protect your family could end up triggering a tax charge that reduces the amount they actually receive.
What Is a Life Insurance Trust?
A life insurance trust is a legal document that separates the ownership of your policy from your personal estate. You (the settlor) transfer the policy into a trust, appoint trustees to manage it, and name beneficiaries who will receive the payout.
Types of trust used for life insurance
| Type | How it works | Best for |
|---|---|---|
| Discretionary trust | Trustees decide how and when to distribute the payout among a class of beneficiaries | Blended families, protecting vulnerable beneficiaries, keeping proceeds out of your estate for IHT |
| Bare trust | Beneficiaries have an absolute right to the proceeds at age 18 (or 21 in Scotland) | Simple situations, children over 18, no need for trustee flexibility |
| Split trust | Combines elements of both – often used for writing a policy that covers both IHT and family needs | Complex estates with multiple objectives |
Most modern life insurance policies offer a “written in trust” option when you apply, which is the simplest way to set it up.
How Does a Life Insurance Trust Cut Inheritance Tax?
The key is removing the policy from your estate. When a life insurance policy is written in trust, the legal ownership passes to the trustees. On your death, the insurer pays the trust directly, not your personal representatives. Because the payout never forms part of your estate, it is not subject to IHT.
Example: You take out a £500,000 life insurance policy. Without a trust, your estate is £500,000 larger, potentially triggering a £200,000 IHT bill. With a trust, the full £500,000 goes to your family – tax free.
The same principle applies to whole‑of‑life and over‑50s policies, though the rules for premiums and potential premium‑gifting need careful handling. Learn more in our guide on Should Your over 50s or Whole‑of‑Life Policy Be Written in Trust?.

Who Should Consider a Life Insurance Trust?
Homeowners with a mortgage or large property value
If your home pushes your estate above the nil‑rate band, a life insurance trust can provide cash to pay the IHT bill without forcing a sale. See our dedicated article: Using a Life Insurance Trust to Cover an Inheritance Tax Bill on Your Home.
Blended families and second marriages
A discretionary trust lets you protect children from a previous relationship while still providing for a new spouse. Learn more in How Life Insurance Trusts Protect Blended Families and Second Marriages from Inheritance Disputes.
