Life Insurance in Trust: How It Avoids Inheritance Tax in 2026/27

Why life insurance can create an unexpected Inheritance Tax bill

Many people assume life insurance is simply a tax-free lump sum for their family. In reality, if a policy is not written in trust, the payout normally becomes part of your estate on death, and is added to everything else you own when calculating Inheritance Tax.

With the nil-rate band frozen at £325,000 and the residence nil-rate band frozen at £175,000 (available where a main residence passes to direct descendants, tapering away above a £2 million estate), a life insurance payout can easily push an otherwise moderate estate over the available thresholds — creating a 40% tax charge on the excess, precisely at the moment your family most needs the funds intact.

How writing a policy in trust solves this

When a life insurance policy is written in trust, the legal ownership of the policy — and therefore the right to the payout — sits with the trustees, for the benefit of the named beneficiaries, rather than with the policyholder personally. Because the proceeds never legally belong to the deceased's estate, two major benefits follow:

1. No Inheritance Tax on the payout. Since the money is not part of the estate, it does not count towards the nil-rate band, residence nil-rate band, or the 40% IHT charge on excess value.
2. No waiting for probate. Trustees can typically present the trust deed and death certificate directly to the insurer and receive the payout, without needing a grant of probate — which for larger or more complex estates can take many weeks or months to obtain.

Discretionary trust vs bare trust

When to set up the trust

The best time to write a policy in trust is at the outset, when you first take out the cover:

• Most insurers offer this as a standard option during the application process, at no additional cost.
• The policy has no value at that point (no premiums paid yet, no payout due), so there is generally no Inheritance Tax consequence of placing it in trust from day one.

Transferring an existing policy into trust later is also possible, but requires more care:

• If the policy already has a surrender value, transferring it into trust can be treated as a gift of that value, and depending on the type of trust and who benefits, this may count as a chargeable lifetime transfer for Inheritance Tax purposes unless covered by an exemption (such as the annual £3,000 gift exemption, or normal expenditure out of income).
• It's worth taking advice before transferring an existing, valuable policy into trust, rather than assuming it's automatically tax-neutral.

Common mistakes to avoid

1. Being offered a trust but never completing it. Many policyholders are told about the trust option at application but never return the signed deed — leaving the policy, and its full value, exposed to Inheritance Tax.
2. Forgetting to update beneficiaries. A trust set up years ago naming an ex-spouse, or excluding children born since, can direct the payout to the wrong people entirely. Review your trust whenever your family circumstances change significantly.
3. Not appointing replacement or additional trustees. If all named trustees predecease the policyholder, the trust can become difficult to administer. Appointing at least two or three trustees, including younger family members where appropriate, reduces this risk.
4. Confusing "in trust" with "invested." A life insurance trust has nothing to do with investment trusts or other financial products — it is simply a legal structure for who owns and controls the insurance payout.
5. Assuming term life insurance doesn't need a trust. Even simple term policies (with no investment value) benefit from being written in trust, purely for the IHT and probate-speed advantages on the death payout.

Practical next steps

• If you're taking out a new policy, ask your insurer or adviser for their standard trust deed at application — this is usually the simplest and cheapest point to act.
• If you have an existing policy not in trust, speak to your insurer about adding a trust, and take advice if the policy already has significant value.
• Review existing trusts every few years, and specifically after any major life event — marriage, divorce, birth of a child, or death of a named trustee or beneficiary.
