Protection Insurance and Inheritance Tax: The Interplay Between Life Cover and Estate Planning

Life assurance and inheritance tax have a relationship that is at once a source of costly planning failures and one of the most effective tools available in estate planning. The same product — a life assurance policy — can either create an inheritance tax problem (if not properly structured) or solve one (if used correctly as an IHT funding vehicle).

Understanding which scenario applies — and how to move from the former to the latter — is one of the most practically important aspects of financial planning for HNW individuals.

This guide examines the full interplay between protection insurance and IHT: when policies form part of the taxable estate, how trust arrangements change this, the specific products designed to fund IHT liabilities, and the additional complexities that apply to internationally mobile individuals.

As of 2026, UK IHT rates and nil-rate bands reflect the position for the 2026/27 tax year. Finance Act 2026 (Royal Assent 18 March 2026) confirmed that unused pension funds will be brought within the IHT estate from 6 April 2027, and changes to Business and Agricultural Property Relief take effect from 6 April 2026. This guide reflects current law and announced changes. Always take current professional advice — the IHT landscape continues to evolve.

Part 1: When Life Assurance Creates an IHT Problem

Policies Not Written in Trust

A life assurance policy that is not written in trust is an asset of the policyholder. On death, the policy matures and the proceeds are paid to the policyholder's estate. The proceeds then form part of the estate for IHT purposes — assessed alongside property, investments, and other assets against the nil-rate band, and taxed at 40% on the excess.

Example:

An individual holds a £1.5 million whole of life policy, a house worth £1.2 million, and investments of £600,000. The standard nil-rate band is £325,000. (The £175,000 residence nil-rate band is tapered away by £1 for every £2 of estate value above £2 million, so on an estate of this size it is fully lost — only the £325,000 NRB is available.)

Asset	Value
House	£1,200,000
Investments	£600,000
Life policy (not in trust)	£1,500,000
Total estate	£3,300,000
Less nil-rate band (£325,000; RNRB tapered to nil)	(£325,000)
Taxable estate	£2,975,000
IHT at 40%	£1,190,000

Of the £1,120,000 IHT bill, £600,000 (roughly) relates directly to the life policy proceeds being included in the estate. The policyholder intended the policy to benefit their family — but without a trust, 40% of the policy proceeds go to HMRC.

This is not an unusual situation. Many individuals — particularly those who arranged life cover many years ago without professional advice — hold large policies outside trust.

The Solution: Write Policies in Trust

Any life assurance policy that is not currently in trust should be reviewed urgently. Writing an existing policy into a suitably structured discretionary trust (see the related guide on trust deed drafting) removes the proceeds from the estate — potentially saving 40% of the policy value in IHT.

The process of assigning an existing policy into trust is straightforward in most cases: the policyholder completes a trust deed or the insurer's standard trust form, and the policy is assigned to the trustees. For UK policies, this is typically available through most major insurers as a standard service.

Important caveat: If the trust is established within seven years of the policyholder's death and the value of the policy at the time of writing into trust exceeds the available nil-rate band, an immediate chargeable lifetime transfer (CLT) arises and IHT may be payable. For most protection policies (where the surrender value is minimal), this is not an issue — the policy value for CLT purposes is typically the surrender value, not the sum assured.

Part 2: Life Assurance as an IHT Solution

The Basic Structure

Life assurance is most commonly used as an IHT planning tool in the following way:

1. The individual (or couple, in the case of a joint life last survivor policy) takes out a whole of life policy for a sum assured equal to the anticipated IHT liability
2. The policy is written into a discretionary trust from inception
3. On death, the policy pays the sum assured to the trustees
4. The trustees distribute the proceeds to the beneficiaries
5. The beneficiaries use the proceeds to pay the IHT liability — typically due within six months of death — without needing to sell estate assets

This structure does not reduce the IHT liability — it provides the cash to pay it. The estate is still subject to IHT at the same rate; the life assurance simply ensures that the heirs can meet this obligation without forced asset sales.

When This Approach Makes Sense

Life assurance for IHT is most appropriate when:

• The IHT liability is quantified and relatively stable (rather than likely to change dramatically)
• The policyholder is in reasonable health and can obtain life assurance at competitive rates
• The policyholder can afford the premiums from income, without material lifestyle sacrifice
• Other IHT planning strategies (gifting, Business Relief, pension funding) have been fully explored but do not eliminate the residual liability

For younger HNW individuals, the premiums for whole of life assurance are relatively low relative to the sum assured, making this an attractive tool. For older individuals (aged 70+), premiums can be substantial — though the "leverage" of life assurance still typically makes it cost-effective relative to the IHT saving.

Products Used for IHT Funding

Whole of life assurance (guaranteed premium, non-linked): The most common choice. A guaranteed premium ensures long-term premium certainty. A non-linked (non-investment) policy provides a fixed, guaranteed sum assured without investment risk.

Reviewable whole of life: Lower initial premium but subject to premium review. Not ideal for IHT planning due to the long-term nature of the commitment.

Investment-linked whole of life (universal life): Provides both a death benefit and an investment element. Used by some HNW clients as an IHT vehicle combined with long-term wealth accumulation. More complex and requires careful management.

Term assurance in trust: For a specific, time-limited IHT liability — for example, a client who has made a potentially exempt transfer (PET) and needs cover for the seven-year survival period — term assurance provides a cheaper temporary solution.

Part 3: Gifts and the Seven-Year Rule

When an individual makes a gift to another person (a PET — Potentially Exempt Transfer), the gift falls outside the estate only if the donor survives seven years. During this period, if the donor dies, the gift is brought back into the estate and may attract IHT (with taper relief reducing the charge after three years).

Life assurance — specifically a decreasing term policy — can be used to cover the "gift inter vivos" risk: the risk that the donor dies within seven years and the gift falls back into the estate. A gift of £500,000 can be backed by a seven-year decreasing term policy providing a death benefit that matches the remaining IHT exposure for each year of the seven-year period.

This is a neat, cost-efficient way to protect the intended gifting strategy without disrupting it.

Part 4: Pension Assets and IHT (The Changing Landscape)

Until recently, pension assets (the unspent funds in a defined contribution pension on death) were broadly outside the IHT estate — a significant planning advantage that has led many HNW individuals to maximise pension contributions as an estate planning tool.

The Autumn Budget 2024 announced that unused pension funds would be brought within the IHT estate, and this is now confirmed in law: Finance Act 2026 (Royal Assent 18 March 2026) provides that unused pension funds and death benefits fall within the IHT estate from 6 April 2027, with the deceased's personal representatives liable for the resulting IHT. The IHT liability for many individuals with large pension pots will increase substantially — increasing the quantum of life assurance required to fund the resulting liability.

The practical impact for existing pension-based estate plans: the residual IHT liability should be recalculated now (or as soon as the final rules are confirmed), and life assurance funding should be adjusted accordingly.

Part 5: Internationally Mobile Individuals — Additional Complexities

Residence and the Reach of UK IHT

From 6 April 2025, the domicile-based system for IHT was abolished and replaced with a residence-based test. The previous concepts of domicile, "domicile of choice", and "deemed domicile" (the old "15 of the previous 20 tax years" rule) no longer determine IHT exposure for deaths and chargeable events on or after that date.

Under the residence-based regime, UK IHT applies to:

• "Long-term UK residents": on their worldwide assets. An individual becomes a long-term resident once they have been UK-resident for at least 10 of the previous 20 tax years.
• Individuals who are not long-term UK residents: only on UK-sited assets (UK property, UK bank accounts, etc.).

An individual who has spent many years outside the UK may fall outside long-term resident status — in which case only their UK assets are within the IHT net. However, "tail" provisions can keep a former long-term resident within the worldwide IHT net for a number of years after they cease UK residence, so the position must be assessed carefully.

For internationally mobile individuals, long-term residence status must be formally assessed before assuming that IHT does not apply to overseas assets.

Overseas Property and Life Assurance

UK IHT applies to the value of UK-sited assets in the estate of an individual who is not a long-term UK resident — and separately, the entire worldwide estate of a long-term UK resident. For the latter, overseas real property, overseas investments, and overseas business interests all form part of the taxable estate.

A long-term UK resident living in the UAE with significant UAE property and UK property faces a potential IHT liability on the combined value of both. Life assurance funding should be sized to cover the full worldwide IHT liability, not just the UK element.

Trust Recognition

Life assurance written into a UK trust is effective for UK IHT purposes — but for internationally mobile individuals, the question of whether the trust is recognised in other jurisdictions (for local succession law or tax purposes) requires separate advice in each jurisdiction.

Common Planning Mistakes

1. Large policies held outside trust — the single most common and costly IHT planning failure
2. Policy written into trust but beneficiaries not updated — a trust deed that names beneficiaries who have died, or doesn't include new children or grandchildren, fails to reflect the client's actual wishes
3. Sum assured not reviewed — estate growth means the IHT liability has increased but the policy sum assured has not kept pace
4. Pension assets not included in the IHT calculation — historically a planning assumption that will need to change post-April 2027
5. Residence status not assessed — assuming UK IHT does not reach overseas assets without a formal assessment of long-term UK residence under the post-April 2025 residence-based rules
6. Trust not reviewed after policy review — the trust structure was appropriate at outset but the family circumstances or jurisdictions of beneficiaries have changed
