Life Insurance Proceeds and UK IHT: The Critical Test for Whether Payouts Are Included in the Estate

A common assumption among UK policyholders is that life insurance payouts automatically bypass Inheritance Tax (IHT). This is not correct. The tax treatment of a life insurance payout depends entirely on a single, critical legal test: whether the proceeds form part of the deceased’s “estate” for IHT purposes. According to HMRC’s Inheritance Tax Manual (IHTM17061, updated 2024), a payout written under a trust is typically outside the estate, while a payout paid directly to the deceased’s personal representatives is included. The distinction carries significant financial consequences. In the 2022–23 tax year, HMRC collected £7.1 billion in IHT receipts (HMRC, 2024, Inheritance Tax Statistics), a figure that has more than doubled from £3.5 billion a decade earlier. For a policy with a sum assured of £500,000, the difference in tax liability can be as much as £200,000 at the current 40% rate. This article explains the decisive test, the role of trusts, and the practical steps policyholders can take to ensure proceeds are not inadvertently swept into the taxable estate.

The Core Test: Written Under Trust vs. Written in Estate

The starting point for any IHT analysis of a life insurance policy is the “written under trust” test. If the policy is written under an absolute or flexible trust, the proceeds are paid directly to the named beneficiaries by the insurer, bypassing the deceased’s estate entirely. HMRC treats such payouts as a gift made on death, but because the gift is from the trust rather than the individual, it does not form part of the estate for IHT purposes.

Conversely, if the policy has no trust and the deceased is the life assured, the proceeds are paid to the deceased’s personal representatives (the executors). This sum is then added to the estate’s value. At the 2024–25 nil-rate band of £325,000, any amount above that threshold is taxed at 40%. For a £500,000 policy, the tax due would be £70,000 (£500,000 less £325,000, taxed at 40%). This is a clean, straightforward calculation. The key takeaway: the policy document itself, not the policyholder’s intention, determines the tax outcome.

The Role of the “Gifts with Reservation” Trap

A common error occurs when a policyholder transfers an existing policy into trust after purchase. If the policyholder continues to pay the premiums or retains any benefit (e.g., the right to surrender the policy), HMRC may treat the arrangement as a “gift with reservation of benefit” (GWR) under the Finance Act 1986, s.102. In such cases, the proceeds remain part of the estate despite the trust. HMRC’s IHTM14311 (2024) confirms that any benefit retained by the settlor—such as the ability to access the policy’s cash value—defeats the tax advantage. This trap is particularly relevant for older whole-of-life policies where the policyholder may have paid premiums for decades.

Trust Structures That Remove Proceeds from the Estate

The most effective way to ensure life insurance proceeds fall outside the estate is to use a “written under trust” arrangement from policy inception. The two most common structures are the absolute trust and the flexible (discretionary) trust.

An absolute trust names specific beneficiaries (e.g., spouse, children) and gives them an immediate, fixed interest in the policy. Once written, the policyholder cannot change the beneficiaries without their consent. This structure is simple and effective: the proceeds are paid directly to the beneficiaries, and HMRC treats them as outside the estate. For a standard term life policy of £500,000, this saves £200,000 in potential IHT.

A flexible trust (often called a discretionary trust) gives the trustees discretion over who receives the proceeds and when. This is useful for blended families or situations where the policyholder wants to protect proceeds from a beneficiary’s creditors or divorce. However, a discretionary trust may give rise to an immediate IHT charge if the premium exceeds the nil-rate band (currently £325,000) in any seven-year period. For most term policies with modest premiums, this is not an issue.

The Spouse Exemption: A Limited Exception

If the policy proceeds are paid directly to the deceased’s estate but the sole beneficiary is a surviving spouse or civil partner, the spouse exemption applies (IHTA 1984, s.18). In this case, the proceeds are inherited tax-free, regardless of whether the policy was written under trust. However, this only defers the tax: on the surviving spouse’s death, the combined estate (including the original proceeds) may exceed two nil-rate bands (£650,000), triggering IHT at 40% on the excess. For a couple with a £500,000 policy, the deferral can be valuable, but it is not a permanent solution.

The Critical Test for “Own Life” Policies

A “own life” policy—where the life assured is also the policyholder—is the most common type of personal life cover. The critical test for IHT purposes is whether the policy is written in trust at the time of death. If it is not, the proceeds are estate assets. If it is, they are not.

Many standard term life policies sold by high-street providers include an option to write the policy under trust at application. Data from the Association of British Insurers (ABI, 2023, UK Insurance and Long-Term Savings: Key Facts) indicates that approximately 40% of new term life policies are written under trust. The remaining 60% are written in the estate, often because the applicant did not understand the tax implications or was not offered the option. For a 40-year-old non-smoker with a £500,000 policy, the difference in annual premium between a trust and non-trust arrangement is typically zero—the trust is simply a legal formality.

The “Seven-Year Rule” for Premiums Paid into Trust

When a policy is written under trust, the premiums paid by the policyholder are treated as potentially exempt transfers (PETs) for IHT purposes. If the policyholder dies within seven years of paying a premium, that premium may be added back to the estate for IHT calculation. However, because premiums are usually small relative to the sum assured (e.g., £50 per month for a £500,000 term policy), the tax on premiums is negligible. The real value—the lump sum payout—remains outside the estate if the trust is correctly drafted.

Practical Steps to Ensure Payouts Are Outside the Estate

For existing policies that are not written under trust, there are limited options. The policyholder cannot simply “assign” the policy to a trust after purchase without triggering the GWR rules. The most reliable solution is to surrender the existing policy and take out a new one written under trust. This is straightforward for term policies with no cash value, but for whole-of-life policies with a surrender value, the policyholder may face a loss. In such cases, a partial surrender or a “trust of the benefit” arrangement may be possible, but this requires specialist legal advice.

For new policies, the process is simple. At application, the policyholder should explicitly request that the policy be written under an absolute trust in favour of the intended beneficiaries. Most insurers provide a standard trust form. The policyholder should name at least one backup beneficiary in case the primary beneficiary predeceases them. Without a backup, the proceeds may revert to the estate.

The Role of Business Life Cover

For business owners, key person insurance or shareholder protection policies are often written on the life of a director. If the policy is owned by the company and pays out to the company, the proceeds are generally outside the director’s personal estate. However, if the policy is owned by the director personally and pays out to the company, HMRC may treat the payment as a transfer of value from the director’s estate. The critical test remains the same: who owns the policy and who are the named beneficiaries? For cross-border premium payments or international policy administration, some families use channels like Airwallex global account to manage multi-currency settlements efficiently.

Case Study: Mrs A and the £600,000 Payout

Mrs A, a 62-year-old widow, held a £600,000 level-term life policy written in her own name with no trust. She intended the proceeds to go to her two adult children. Upon her death in 2023, the payout was paid to her estate. After deducting her nil-rate band of £325,000, the remaining £275,000 was subject to IHT at 40%, resulting in a tax bill of £110,000. Her children received £490,000 instead of the full £600,000.

Had Mrs A written the policy under an absolute trust naming her children as beneficiaries, the full £600,000 would have passed to them tax-free. The cost of the trust documentation was a one-time fee of approximately £150 from a solicitor. The £110,000 tax saving represents a 73,300% return on that cost. This case illustrates the critical financial impact of the trust decision.

Case Study: Mr B and the Discretionary Trust for Blended Family

Mr B, aged 55, had a £400,000 whole-of-life policy and a blended family: two children from a first marriage and a second wife. He wrote the policy under a discretionary trust, naming his second wife and both children as potential beneficiaries. The trustees (his solicitor and his brother) had discretion to allocate proceeds. Upon Mr B’s death in 2024, the trustees allocated £200,000 to his wife (spouse-exempt, no IHT) and £200,000 to his children (outside the estate, no IHT). The total tax saving was £80,000. The discretionary trust also protected the children’s share from any future claims by the wife’s creditors.

FAQ

Q1: If I have a life insurance policy written in my own name, can I transfer it into a trust to avoid IHT?

Transferring an existing policy into trust after purchase is possible but risky. If you continue to pay the premiums or retain any benefit (e.g., the right to surrender), HMRC will treat the arrangement as a gift with reservation of benefit, meaning the proceeds remain in your estate. The safest approach is to surrender the existing policy and take out a new one written under trust. For a £500,000 policy, the tax saving can be £200,000, far outweighing any surrender loss.

Q2: Does the spouse exemption apply to life insurance payouts?

Yes, if the policy proceeds are paid to the estate and the sole beneficiary is a surviving spouse or civil partner, the spouse exemption applies, meaning no IHT is due on that transfer. However, this only defers the tax. On the surviving spouse’s death, the combined estate may exceed two nil-rate bands (£650,000), triggering IHT at 40% on the excess. For a couple with a £500,000 policy, the deferral is valuable, but writing the policy under trust for children is often more tax-efficient.

Q3: What happens if I die within seven years of paying premiums into a trust?

Premiums paid into a trust are treated as potentially exempt transfers (PETs). If you die within seven years of paying a premium, that premium amount is added back to your estate for IHT calculation. However, because premiums are typically small (e.g., £50–£100 per month), the tax impact is negligible. The lump sum payout—the main value—remains outside the estate if the trust is correctly drafted. For a £500,000 policy with £600 annual premiums, the maximum IHT on premiums would be £240 (40% of £600), a fraction of the £200,000 tax saved on the payout.
