How IHT Applies to Life Insurance

In the UK, life insurance death benefits are included in the deceased's estate when calculating Inheritance Tax. IHT applies at 40% on the value of the estate above the Nil Rate Band — currently £325,000 per individual, or £650,000 for married couples and civil partners using the transferable nil rate band.

The Residence Nil Rate Band adds up to £175,000 per person (£350,000 for couples) when the estate includes a qualifying home passed to direct descendants. But this additional allowance tapers for estates worth more than £2 million, reducing by £1 for every £2 above that threshold.

A life insurance payout that pushes the estate above these thresholds can trigger IHT on the excess. For families who bought life insurance specifically to provide financial security after death, discovering that IHT can apply at 40% to the amount above the available thresholds is a harsh outcome.

Writing the Policy in Trust

The most effective way to keep life insurance out of the taxable estate is to write the policy in trust from the outset. This means the trust — not the individual — owns the policy and receives the death benefit. Because the proceeds never form part of the deceased's estate, they're excluded from the IHT calculation entirely.

Most UK insurers offer standard trust forms as part of the policy application process. It's typically a straightforward form completed at the time of purchase, naming the trustees and beneficiaries. Setting this up at inception costs nothing and takes minutes.

A policy written in trust also bypasses probate. While a probated estate can take months to settle — during which assets are frozen — trust-held life insurance can pay out within days of the death certificate being issued. This speed matters when families need the proceeds to cover funeral costs, mortgage payments, or the estate's own IHT bill.

If a policy wasn't written in trust at inception, it can be assigned into trust later, but the IHT treatment depends on the trust type.

The Seven-Year Rule

Gifts to individuals and certain bare trusts that exceed the £3,000 annual gift allowance may be "potentially exempt transfers" (PETs). If the donor survives seven years from the date of the gift, the transfer becomes fully exempt from IHT. If the donor dies within seven years, the gift is included when calculating IHT, with taper relief reducing the tax charge on gifts made more than three years before death.

Assigning an existing life insurance policy into trust is a transfer of value, but the IHT treatment depends on the trust type. A transfer into most discretionary trusts is an immediately chargeable lifetime transfer; a gift into a bare trust can be a PET and may become chargeable if the donor dies within seven years. Writing the policy in trust from day one avoids a later assignment of an existing policy, but premium gifts and trust charges still need to be considered.

For term insurance (which has no cash surrender value), the value of the transfer is typically negligible. For whole-of-life policies with significant cash value, the transfer value can be substantial.

The Nil Rate Band in Practice

The £325,000 nil rate band has been frozen since 2009 and is currently set to remain frozen through 5 April 2031. Meanwhile, property values and accumulated pension wealth have continued rising, pulling more estates above the threshold each year.

The transferable nil rate band allows a surviving spouse or civil partner to carry over any unused portion of the first-to-die's allowance. If the first spouse used none of their nil rate band (because everything passed to the surviving spouse exempt from IHT), the survivor's estate effectively has a £650,000 allowance.

Combined with two Residence Nil Rate Band allowances of £175,000 each, a married couple's estate can shield up to £1 million from IHT — provided the estate includes a qualifying home passing to direct descendants and the total estate value doesn't trigger the taper.

Recent Changes to Watch

Two changes affect estate planning from April 2026 onward. From 6 April 2026, the 100% Agricultural and Business Property Relief allowance is £2.5 million of combined qualifying property; qualifying value above that receives 50% relief, an effective 20% IHT rate. From 6 April 2027, most unused pension funds and pension death benefits will be brought into the estate for IHT purposes — a significant change that may push previously sub-threshold estates above the nil rate band.

For families whose estates are close to or above the threshold, reviewing life insurance trust arrangements alongside these new rules is worth doing sooner rather than later.
