Whole of Life Insurance in Trust UK: Funding Your IHT Bill with a Policy in Trust (2026)
A whole-of-life policy written in trust pays out on death outside the IHT estate — funding the IHT bill without executors having to sell assets. Premiums paid regularly from surplus income are immediately IHT-exempt (s21 IHTA 1984). A Gift Inter Vivos (GIV) policy covers the reducing PET liability over the seven-year taper period.

Whole of Life Insurance in Trust: Everything You Need to Know
Why a whole-of-life policy in trust is the most common IHT solution
A whole-of-life assurance policy pays out a guaranteed sum on the policyholder's death (unlike term insurance which expires after a fixed period). If the policy is written in trust, the sum assured belongs to the trust on payout — not to the policyholder's estate — so it is outside the IHT estate and paid to the trust beneficiaries without IHT. The payout is then available to fund the IHT bill. The IHT advantages of a whole-of-life policy in trust: (1) The policy payout is outside the estate — no IHT on the payout itself; (2) The cash is available quickly to executors/beneficiaries (trust payouts typically much faster than probate); (3) The IHT bill can be paid without having to sell the family home, business, or investments to raise cash. The practical problem the policy solves: IHT must generally be paid before probate is granted (with limited exceptions). Without liquid funds, executors face a 'chicken and egg' problem — they cannot sell estate assets (which requires a grant of probate) but cannot get probate without paying IHT. A whole-of-life policy in trust provides ready cash to pay HMRC, avoiding this problem.
Types of trust for a whole-of-life policy
The most common trust structures for a whole-of-life policy are: (1) Discretionary trust: the trustees decide who receives the payout from a class of potential beneficiaries (e.g. spouse, civil partner, children, grandchildren). The policyholder fills in a 'letter of wishes' (expression of wishes — not legally binding on trustees, but taken seriously). A discretionary trust provides flexibility: trustees can allocate the payout to the beneficiaries most in need, avoiding the trust fund being used to pay the beneficiary's own IHT. (2) Absolute (bare) trust: a specific beneficiary receives the payout absolutely — simpler and more certain, but inflexible if circumstances change. (3) Married Women's Property Act 1882 (MWP) trust: a life policy taken out for the benefit of a spouse, civil partner, or children under s11 MWP Act 1882 is automatically in trust — no formal trust deed required. The policy is written 'for the benefit of [spouse/civil partner] and/or children'. Simple, fast, and cheap — but with less flexibility than a discretionary trust; the trust beneficiaries cannot be changed after the policy is written. IHT treatment: all these trust structures keep the policy outside the estate for IHT. Periodic charges: a discretionary trust holding a life policy is in the relevant property regime — potentially subject to 6% periodic charges every 10 years on the surrender value (which may be minimal for a whole-of-life policy during the holding period). The periodic charge is usually very small as the annual premium value is typically much lower than the NRB.
Premiums as normal expenditure from income: the key IHT saving
The premium payments themselves are potentially IHT-exempt under the normal expenditure from income exemption (s21 IHTA 1984) — if they form part of the policyholder's normal pattern of expenditure from surplus income. The conditions for the s21 exemption: (1) The premium payments are regular (e.g. monthly or annual standing order — not sporadic); (2) The premiums are paid from income (not from capital savings); (3) After paying the premiums, the policyholder retains sufficient income to maintain their usual standard of living. Where these conditions are met, the premium payments are immediately exempt from IHT — there is no seven-year clock. This is the most powerful aspect of using a whole-of-life trust policy for IHT planning: the premiums leave the estate immediately, and the payout funds the IHT bill. Over a 20-year period, a policyholder paying £5,000/year in premiums will have removed £100,000 from their estate — immediately exempt if from surplus income. Evidence of normal expenditure: keep records of income and expenditure showing the premiums come from surplus income. Form IHT403 (Gifts and other transfers of value) asks HMRC for evidence; without records, the exemption may be challenged.
Gift Inter Vivos (GIV) policy: covering the reducing PET liability
When a person makes a large gift (a PET), the IHT liability reduces over seven years due to taper relief: years 1–3: full 40%; year 3–4: 32%; year 4–5: 24%; year 5–6: 16%; year 6–7: 8%; after 7 years: nil. A Gift Inter Vivos (GIV) policy provides a decreasing amount of life cover that exactly tracks the reducing IHT liability on the PET over the seven-year period. How GIV works: the donor takes out a GIV policy immediately after making the PET; the policy pays out only if the donor dies within seven years; the payout equals the IHT that would be payable on the PET at the date of death (accounting for taper relief for the years survived); the policy is typically written in trust for the donee (the recipient of the PET) — so the IHT is paid without the donee having to find the cash. Who needs a GIV policy: any person making a large PET (gift of £100,000+) where the donor's health means there is a material risk of death within seven years. A GIV policy is low-cost (because the cover decreases to nil over seven years) and can be written in trust for the donee. It ensures that a gift does not create an IHT liability the donee cannot pay.
Assigning an existing policy into trust
If you already have a whole-of-life policy that is NOT in trust (it is personally owned — part of your estate), you can assign it into trust at any time. The assignment: (1) Creates a trust of the policy (using the insurer's standard trust deed or a separately drafted trust); (2) You as the policyholder are the settlor; (3) The trustees are typically yourself plus two others (spouse/partner and an adult child); (4) The beneficiaries are typically your spouse/civil partner and/or children (and/or grandchildren). IHT effect of assigning a policy into trust: the policy moves from your estate into the trust — a gift of the surrender value (not the sum assured) at the date of assignment. If the surrender value is low (as it typically is for a whole-of-life policy in the early years), this is a PET of low value — potentially covered by the annual exemption or below the NRB. After assignment: premiums paid are potentially normal expenditure from income (s21 exemption). On death: the policy payout goes to the trust — outside the estate. Key point: once assigned, you can no longer unilaterally revoke the trust or take the policy back — it belongs to the trustees. Ensure the trust terms and beneficiary nominations reflect your current wishes.
How much cover do you need? Calculating the IHT liability
To calculate the appropriate level of whole-of-life cover for IHT purposes: (1) Calculate your likely IHT liability: total estate value (property + investments + cash + business interests) minus applicable NRB (£325,000) minus RNRB (if home passes to direct descendants — £175,000) minus spousal exemption (assets passing to spouse) = taxable estate × 40% = IHT liability. (2) Consider the effect of future growth: estates typically grow over time; the sum assured should be reviewed periodically (every 3–5 years) to reflect changes in estate value, NRB levels, and asset values. (3) Consider the transferable NRB: if you are married and your spouse predeceased you, the second death estate has a doubled NRB — the cover needed may be lower on the second death than on the first. (4) Consider BPR/APR: if a significant part of the estate qualifies for BPR or APR, the IHT exposure (and therefore the cover needed) is reduced. (5) Account for available NRB at death: if large PETs have been made in the seven years before death, the NRB may be fully or partly used against those PETs — leaving less NRB available for the estate. Review the cover amount annually — particularly where the estate is growing, where PETs have been made, or where significant asset acquisitions (inheritance, business sale) have increased the estate value.
Frequently Asked Questions
Does a whole of life insurance policy avoid inheritance tax?
A whole-of-life policy is in the IHT estate if you own it personally — the surrender value is an estate asset during life, and the sum assured is paid to the estate on death (subject to IHT). To keep the payout outside the IHT estate, the policy must be written in trust (or assigned into trust) before death. The trust — not you — owns the policy; the payout goes to the trust beneficiaries on death, free of IHT. Premium payments into an in-trust policy may qualify as normal expenditure from income (s21 IHTA 1984) — immediately IHT-exempt.
What is a Gift Inter Vivos (GIV) policy?
A GIV (Gift Inter Vivos) policy is a decreasing life insurance policy that covers the IHT liability on a PET (Potentially Exempt Transfer) over the seven-year taper period. If the donor dies within seven years of making the gift, the GIV policy pays out the IHT that would be due at that date (accounting for taper relief for years survived). The policy is written in trust for the donee — so the IHT is funded without the donee needing to find the cash. GIV cover decreases to nil at the end of year seven (when the PET becomes fully exempt).
Can I write a life insurance policy in trust without a solicitor?
Yes. Most major insurers provide standard in-trust documentation (often called a 'trust form' or 'in-trust application') that you can complete when the policy is taken out — without needing a separate trust deed or solicitor involvement. For a Married Women's Property Act 1882 (s11) trust, writing the policy 'for the benefit of my spouse and/or children' creates the trust automatically. For a discretionary trust, a more formal trust deed may be needed — your insurer or a financial adviser can assist. Keep the trust deed and nominations safe, alongside your will.
What is the Married Women's Property Act 1882 trust for life insurance?
Section 11 of the Married Women's Property Act 1882 allows a life insurance policy to be written for the benefit of a spouse, civil partner, or children — automatically creating a statutory trust without a separate formal trust deed. The policy is held in trust for the named beneficiaries; the payout on death goes to them outside the policyholder's estate. It is simple and widely used — but less flexible than a discretionary trust (the beneficiaries cannot be changed after the policy is written). For most straightforward IHT planning, an MWP Act trust is sufficient.
Can I claim IHT relief on life insurance premiums?
Premiums paid into a life policy in trust may qualify as normal expenditure from income (s21 IHTA 1984) — immediately IHT-exempt, with no seven-year clock. Requirements: (1) Regular payments (monthly or annual standing order); (2) From income (not from capital); (3) Leaving the donor with sufficient income for their usual standard of living. Keep records of income and expenditure to evidence the exemption — form IHT403 asks for this evidence. Without records, HMRC may challenge the exemption, treating the premiums as PETs (seven-year clock applies).
