Life insurance and Inheritance Tax in the UK

Life insurance is one of the most common tools people reach for when they hear they might have an Inheritance Tax bill — but a policy on its own doesn't automatically avoid tax, and getting the details wrong is a common, costly mistake. Here's how it actually works.

Not financial advice. This is general information about how life insurance and Inheritance Tax interact under current UK rules. Speak to a solicitor and a financial adviser who specialises in estate planning before arranging or changing a policy.

Does a life insurance payout count towards Inheritance Tax?

By default, yes. If you own a life insurance policy personally, its payout becomes part of your estate when you die — the same as a bank account or a house — and is assessed for Inheritance Tax alongside everything else you own. This surprises a lot of people, since the money is intended for their family, not for HMRC.

The one thing that changes this: writing the policy in trust. A policy held in trust pays out directly to your named beneficiaries, doesn't form part of your taxable estate at all, and doesn't have to wait for probate to be granted — which matters, because probate can take months, and a family sometimes needs cash quickly to cover funeral costs or the estate's own tax bill.

Writing a policy in trust

"In trust" isn't just a phrase on an application form — it means the policy is legally owned by trustees (people you choose, often including yourself) for the benefit of the people you name. Most insurers provide a standard policy trust form for exactly this purpose, and it needs to actually be completed and signed, ideally at the same time you take the policy out.

A few things worth getting right:

  • Choose trustees you trust to act promptly and follow your wishes — this is commonly you, your spouse or partner, and one adult child or close relative.
  • Name your actual intended beneficiaries on the trust, not just "my estate" — naming your estate defeats the point, since it brings the payout straight back into your taxable estate.
  • Review the trust if your family circumstances change — divorce, remarriage, a new child, or a beneficiary's death can all mean the trust no longer reflects what you actually want.
  • Check with your provider if you're not sure whether an existing older policy is already written in trust — it's common for people to genuinely not know.

Whole-of-life cover, or a policy tied to a specific gift?

There are two quite different reasons people take out life insurance as part of estate planning, and they call for different types of policy:

Funding the Inheritance Tax bill itself. A whole-of-life policy (cover that lasts for the rest of your life, rather than a fixed term) written in trust is the common choice here, since nobody knows in advance when an IHT bill will actually fall due. The payout gives your executors cash on hand to help settle the bill, without needing to sell a house or other illiquid assets under time pressure.

Covering the risk on a lifetime gift. If you've made (or are planning) a large gift and are relying on surviving 7 years for it to fall outside your estate, a reducing "gift inter vivos" term policy specifically covers the tax that would be due if you die within that window — the cover amount steps down roughly in line with taper relief, since the potential tax bill shrinks the same way the longer you survive.

How much cover do you actually need?

This depends entirely on your own numbers — the size of your estate, your nil-rate bands, what's already exempt (like anything left to a spouse or charity), and any reliefs that already apply. A rough rule of thumb isn't very useful here, because Inheritance Tax is genuinely a "your specific situation" calculation.

Legacy Protector's simulator is built for exactly this — it works out your estimated Inheritance Tax bill from your own assets, allocations and any strategies you're considering, so a life insurance policy (in trust) can be sized against a real number instead of a guess.

Common mistakes

  • Not writing the policy in trust. By far the most common gap — the payout ends up back in the taxable estate, and can also be delayed by probate.
  • Assuming insurance "solves" Inheritance Tax. A policy pays for the bill; it doesn't reduce it. Reliefs, exemptions, gifting and the structure of your estate are what actually reduce the tax itself — insurance and estate planning usually work together, not as alternatives.
  • Letting cover lapse or go out of date. A term policy that expires before an IHT liability arises provides no protection when it's actually needed.
  • Forgetting to update the trust after a major life change, so the payout goes to the wrong people or via the wrong route.
