Inheritance tax is charged at 40% on estates above £325,000. Without planning, your beneficiaries may face a cash-flow crisis — forced to sell the family home to pay HMRC within six months. Life insurance, placed in trust, provides the liquidity to pay the bill without selling a single asset.
Most UK estates are asset-rich but cash-poor. The family home may be worth £600,000, but the estate may hold only £20,000 in liquid savings. When HMRC demands 40% of the amount above £325,000 — in this case £110,000 — within six months of death, beneficiaries face an impossible choice: sell the property quickly at a discount, or borrow at high cost.
This is the inheritance tax liquidity problem. It affects families across the UK, particularly those whose wealth is concentrated in property. Life insurance, structured correctly, solves it entirely — providing a guaranteed cash sum at exactly the moment it is needed.
The probate delay compounds the problem
Probate — the legal process of administering an estate — typically takes 12 to 18 months. During this time, assets are frozen. A life insurance policy placed in trust bypasses probate entirely, paying out directly to beneficiaries within weeks of the death being registered.
Not all life insurance policies are equally suited to inheritance tax planning. The right type depends on your circumstances, estate size, and whether you are covering a permanent liability or a time-limited gift.

This is the single most important step in life insurance IHT planning. Without trust placement, the policy payout joins your estate — and is itself subject to 40% inheritance tax.
Without a trust, the life insurance payout is added to your estate and taxed at 40%. Placing the policy in trust keeps the payout entirely separate.
Probate can take 12–18 months. A trust-held policy pays out directly to beneficiaries, giving them the cash to pay HMRC within the six-month deadline.
Inheritance tax must be paid within six months of death or interest accrues. A trust-held policy provides the liquidity to meet this deadline without selling assets.
A discretionary trust gives trustees flexibility to distribute the payout among beneficiaries in the most tax-efficient way at the time of your death.
Worked example: the cost of not using a trust
Suppose a whole-of-life policy pays out £200,000 on death. Without a trust, this £200,000 is added to the estate. If the estate is already above the nil-rate band, 40% of £200,000 = £80,000 goes to HMRC. The beneficiaries receive only £120,000 — not the £200,000 intended. With a trust, the full £200,000 passes directly to beneficiaries, tax-free.
Transfers between spouses and civil partners are exempt from inheritance tax. This means that when the first spouse dies, no IHT is payable — the entire estate passes to the survivor tax-free. The IHT liability only crystallises on the second death, when the combined estate passes to the children or other beneficiaries.
A joint life second death policy is designed precisely for this scenario. It covers both lives and pays out only after the second death — exactly when the IHT bill falls due. Because the insurer is covering two lives before paying out, premiums are significantly lower than two separate whole-of-life policies.

When you make a large lifetime gift — for example, transferring a property to your children — it becomes a Potentially Exempt Transfer (PET). If you survive seven years, the gift is entirely free of IHT. But if you die within seven years, the gift is brought back into your estate and taxed, with taper relief reducing the rate after year three.
Gift inter vivos insurance is a decreasing term policy that covers this risk. The sum assured starts at the maximum potential IHT liability and decreases each year in line with taper relief. By year seven, the cover reaches zero — because the gift is then fully exempt.
| Years since gift | IHT rate | Tax on £175,000 excess | Policy cover needed |
|---|---|---|---|
| 0–3 years | 40% | £70,000 | £70,000 |
| 3–4 years | 32% | £56,000 | £56,000 |
| 4–5 years | 24% | £42,000 | £42,000 |
| 5–6 years | 16% | £28,000 | £28,000 |
| 6–7 years | 8% | £14,000 | £14,000 |
| 7+ years | 0% | £0 | £0 (exempt) |
Note: This example assumes the gift exceeds the nil-rate band. If the donor has used their NRB on other gifts, the taxable amount may differ. Seek professional advice for your specific circumstances.
Follow these three steps to put a life insurance IHT strategy in place.
Add up all assets — property, savings, investments, business interests, and personal possessions. Deduct debts and liabilities. Subtract the nil-rate band (£325,000) and, if applicable, the residence nil-rate band (£175,000). The remainder is your potential IHT liability at 40%.
Approach a whole-of-life insurer or independent financial adviser. For couples, compare joint life second death policies against two separate whole-of-life policies. For recent large gifts, ask specifically about gift inter vivos decreasing term cover.
Instruct a solicitor to draft a trust deed — typically a discretionary trust — and assign the policy to it immediately. This step is critical: without it, the payout joins your estate and is itself subject to inheritance tax.
Premium payments are treated as gifts from the policyholder to the trust. This raises the question of whether the premiums themselves attract IHT. The answer depends on how they are funded.
If the premiums are paid from regular surplus income — and do not affect your standard of living — they qualify for the normal expenditure out of income exemption. They are immediately exempt from IHT, with no seven-year wait and no limit on the amount.
If the premiums do not qualify as normal expenditure out of income, they may be covered by the annual £3,000 gifting exemption. Premiums above this level that are not covered by another exemption are treated as PETs and subject to the seven-year rule.

Common questions about using life insurance to cover inheritance tax.
Only if it is not placed in trust. A life insurance policy that pays out to your estate is included in the estate valuation and taxed at 40% on the amount above the nil-rate band. If the policy is written in trust, the payout goes directly to the beneficiaries and is not part of your estate.
A joint life second death (also called "last survivor") policy covers two lives and pays out only after both have died. Because inheritance tax between spouses is generally deferred until the second death, this policy aligns precisely with when the IHT bill actually falls due. Premiums are lower than two separate whole-of-life policies.
Gift inter vivos insurance is a decreasing term policy taken out to cover the inheritance tax risk on a large lifetime gift — typically a Potentially Exempt Transfer (PET). If the donor dies within seven years, the gift may attract IHT. The policy pays out to cover that liability, decreasing in line with taper relief over the seven-year period.
The starting point is your estimated IHT liability: 40% of the estate value above the nil-rate band (£325,000) and, where applicable, the residence nil-rate band (£175,000). For a couple, the combined threshold can reach £1 million. A financial adviser can model the precise figure based on your estate composition and any existing reliefs.
Yes. Most insurers allow you to assign an existing policy into trust at any time, provided the policy has not already paid out. The assignment is usually straightforward and does not require a new policy. You should act promptly — the sooner the policy is in trust, the sooner the payout is protected from IHT.
A discretionary trust is the most common choice. It gives trustees flexibility to distribute the payout among a class of beneficiaries in the most tax-efficient way at the time of death. A bare trust is simpler but less flexible. Your solicitor will advise on the most appropriate structure for your circumstances.
Premium payments are treated as gifts. If they fall within the normal expenditure out of income exemption — regular payments from surplus income that do not affect your standard of living — they are immediately exempt from IHT. Otherwise, they may count towards your annual £3,000 gifting allowance.
For covering a permanent IHT liability (the nil-rate band shortfall on your estate), whole-of-life insurance is generally preferable because it guarantees a payout whenever you die. Term insurance is more appropriate for time-limited risks, such as covering the seven-year PET period on a large gift.
