Life Insurance in Trust to Avoid Inheritance Tax (UK)

In the UK, life insurance proceeds from a policy owned by the deceased may be included in the estate for Inheritance Tax (IHT) unless the policy is effectively held in trust. That can mean a 40% tax on amounts above the applicable nil rate band — and a family that thought they were receiving a financial safety net can lose nearly half of it to HMRC.

How Writing a Policy in Trust Works

When a policy is validly placed in trust, trustees hold it separately from the deceased's estate. The payout is generally paid under the trust rather than through the estate, but transfer, premium, and trust rules can still affect IHT.

The practical benefits are significant:

• Potentially no IHT on the death benefit if the policy is properly held in trust; transfer, premium, and trust rules can still apply
• No probate delays — funds release directly to beneficiaries, often within weeks rather than the months probate can take
• Immediate liquidity — the payout can be used to cover the estate's own IHT bill on other assets (property, investments, pensions) so the family doesn't have to sell the house to pay the tax

Most UK life insurers offer trust forms as a free option when you take out a policy. Setting one up after the policy is issued is still possible but involves more paperwork.

The 7-Year Rule

Transferring an existing policy into trust can be a lifetime transfer for IHT purposes. Depending on the trust type, the transfer may be immediately chargeable or may be a potentially exempt transfer (PET). If IHT is due on the transfer and you die within seven years, it is based on the value transferred, subject to available exemptions and thresholds. This does not mean the full death benefit is automatically pulled back into your estate.

If IHT is due on a PET because total gifts exceed the available nil rate band, taper relief can reduce the tax on that gift after three years; it does not reduce the policy's death benefit. The rates are:

• 0 to 3 years: full 40% IHT rate
• 3 to 4 years: 32%
• 4 to 5 years: 24%
• 5 to 6 years: 16%
• 6 to 7 years: 8%
• 7+ years: fully exempt

This is why estate planners recommend writing policies in trust as early as possible — ideally when the policy is first purchased. A new policy taken out for trust beneficiaries may keep the death benefit outside the settlor's estate when structured properly, but the cost of setting it up and ongoing premiums can be gifts for IHT purposes.

The Nil Rate Band and When It Matters

The standard nil rate band is £325,000 — the threshold below which no IHT is due. There's also the residence nil rate band (up to £175,000 for a qualifying family home passed to direct descendants), bringing the potential combined threshold to £500,000 per person or £1 million for a married couple.

Where life insurance intersects with IHT planning:

If the deceased's estate (property, savings, investments, and any insurance proceeds not in trust) exceeds the applicable thresholds, the excess is generally taxed at 40%. Assuming no residence nil rate band or other relief applies, a £300,000 life insurance payout on someone whose estate is already at £400,000 means £375,000 is subject to IHT — a £150,000 tax bill that didn't need to exist.

For deaths on or after 6 April 2026, 100% agricultural and business relief is capped at £2.5 million in combined qualifying property. From 6 April 2027, most unused pension funds and pension death benefits are brought into scope of IHT. These changes make trust-based IHT planning more relevant than ever for estates that previously relied on those reliefs to stay below threshold.

Premium Payments and Annual Gift Allowances

Ongoing premium payments on a trust policy can be gifts. A payment may be covered by the £3,000 annual exemption or the exemption for regular gifts out of income (payments from surplus income that don't affect the policyholder's standard of living), if its conditions are met.

Amounts not covered by an exemption may be potentially exempt transfers or immediately chargeable transfers, depending on the trust arrangement. The 7-year rule can apply. For high-value policies with substantial premiums, this needs careful planning.
