Inheritance Tax (IHT) is often called a 'voluntary tax' by financial experts, but for a growing number of UK families, it feels anything but optional. With frozen tax-free allowances and rising property values, more estates than ever are being caught in the IHT net.
Indeed, the latest figures from HM Revenue and Customs (HMRC) reveal that IHT receipts reached a record £7.5 billion in the 2023/24 tax year. This upward trend underscores a critical reality: without careful planning, a significant portion of the wealth you’ve worked a lifetime to build could be handed over to the taxman instead of your loved ones.
Fortunately, there is a highly effective, legitimate, and straightforward strategy to address this: Whole of Life insurance. This guide will explore how this powerful financial tool can be used to provide a tax-free lump sum to cover a future IHT bill, ensuring your legacy is passed on intact.
The core concept is brilliantly simple. A Whole of Life insurance policy is a type of permanent life cover that guarantees to pay out a lump sum whenever you die, as long as you have kept up with your monthly premiums.
For estate planning, the strategy works like this:
The result? Your beneficiaries inherit your entire estate as you intended, with the tax liability neatly settled by the insurance policy. It's a clean, efficient, and predictable way to protect your legacy.
To appreciate the value of Whole of Life insurance, it's essential to grasp the basics of Inheritance Tax. IHT is a tax on the 'estate' of someone who has died, which includes their property, money, and possessions.
The key components for 2025 are:
Nil-Rate Band (NRB): Every individual has a tax-free allowance of £325,000. Your estate will not pay any IHT on the first £325,000 of its value. This threshold has been frozen since 2009 and is expected to remain so until at least 2028, a factor known as 'fiscal drag' which pulls more estates into the tax net over time.
Residence Nil-Rate Band (RNRB): An additional allowance of £175,000 is available if you pass your main home to your children, grandchildren, or other direct descendants. This means a qualifying individual could have a total tax-free allowance of £500,000.
Transferable Allowances: Spouses and civil partners can transfer any unused NRB and RNRB to the surviving partner. This means a married couple could potentially pass on up to £1 million tax-free (£325k + £175k from the first partner, plus £325k + £175k for the second partner).
The IHT Rate: Any part of your estate valued above your combined allowances is typically taxed at a flat rate of 40%.
Let's look at the potential allowances for an individual and a couple.
| Allowance Type | Individual | Married Couple / Civil Partners (Combined) |
|---|---|---|
| Nil-Rate Band (NRB) | £325,000 | £650,000 |
| Residence Nil-Rate Band (RNRB) | £175,000 | £350,000 |
| Total Potential Allowance | £500,000 | £1,000,000 |
The 40% tax rate can have a substantial impact. For an estate worth £1.5 million, with full allowances of £1 million used, the remaining £500,000 would face a tax bill of £200,000. This is a significant sum that must be paid before your beneficiaries can receive their inheritance.
Whole of Life insurance is distinct from the more commonly known 'term' life insurance. Understanding the difference is key to its application in estate planning.
Term Life Insurance: Provides cover for a fixed period (e.g., 20 or 25 years). It pays out if you die within that term. It’s primarily designed to cover temporary needs, like paying off a mortgage or protecting your family while your children are financially dependent. If you outlive the term, the policy ends and there is no payout.
Whole of Life Insurance: As the name suggests, this policy covers you for your entire life. As long as you maintain your premium payments, a payout upon your death is a certainty. It's a case of when it will pay out, not if. This certainty is what makes it the ideal instrument for settling a certain future liability like an IHT bill.
There are two main types of Whole of Life policies, each with different premium structures:
| Policy Type | Premium Structure | Best For | Key Consideration |
|---|---|---|---|
| Guaranteed Premiums | Fixed from day one and will never change. | Those who value budget certainty and want no future surprises. | Premiums are higher from the start compared to reviewable options. |
| Reviewable Premiums | Lower initial premiums, but they are reviewed by the insurer every 5 or 10 years. | Younger individuals who may have less disposable income now but expect it to grow. | Premiums can, and often do, increase significantly at review points, potentially becoming unaffordable later in life. |
Choosing between guaranteed and reviewable premiums is a critical decision. While reviewable premiums are tempting due to their lower initial cost, the risk of steep increases in your 70s or 80s, when your income may be fixed, can be substantial. Guaranteed premiums offer complete peace of mind, though at a higher initial price.
Simply buying a Whole of Life policy isn't enough for effective IHT planning. The single most important step is to place the policy into a Trust.
Why is a Trust so vital?
Without a Trust, the lump sum payout from the life insurance policy is legally considered part of your estate. This means it would be added to your other assets, potentially increasing the value of your estate and, ironically, increasing the very IHT bill it was designed to pay.
How does a Trust work?
A Trust is a simple legal arrangement that separates the ownership of the policy from you.
By writing the policy in Trust, the payout goes directly to the trustees for the benefit of your beneficiaries. It completely bypasses your estate and the probate process.
Key Benefits of Using a Trust:
Insurers make this process very straightforward. In most cases, the trust forms are provided free of charge when you set up your policy. At WeCovr, we guide every client through this essential step to ensure their policy is structured for maximum tax efficiency.
To determine how much Whole of Life cover you need, you must first perform a "dummy" IHT calculation on your estate.
Here is a step-by-step guide:
Step 1: Value Your Estate List all your worldwide assets and assign a realistic current market value.
Step 2: Deduct Liabilities Subtract any outstanding debts.
The result is your 'Net Estate'.
Step 3: Apply Your Allowances Subtract your available Nil-Rate Bands (NRB and RNRB). For a couple, the calculation is usually performed on the second death, assuming all assets and allowances pass to the surviving spouse first.
Step 4: Calculate the Tax The remaining value is your 'Taxable Estate'. Apply the 40% IHT rate to this figure to find your potential IHT bill. This is the amount of Whole of Life cover you should consider.
Real-Life Example: David and Sarah
Let's imagine a married couple, David and Sarah, both aged 60. They want to ensure their two children can inherit their estate without a crippling tax bill.
| Asset | Value | Notes |
|---|---|---|
| Family Home | £850,000 | Jointly owned. |
| Savings & ISAs | £300,000 | Combined savings. |
| Share Portfolio | £200,000 | Investments held. |
| Cars & Possessions | £50,000 | Estimated value. |
| Total Gross Estate | £1,400,000 | |
| Mortgage | (£100,000) | Outstanding balance. |
| Total Net Estate | £1,300,000 |
IHT Calculation (on second death):
To cover this liability, David and Sarah could take out a joint-life, second-death Whole of Life policy for £120,000. This type of policy is specifically designed for IHT planning and only pays out after the second partner dies, which is when the tax bill becomes due. Because it's a 'second death' policy, the premiums are significantly cheaper than two single policies.
By placing this policy in trust for their children, the £120,000 payout would be used to settle the tax bill, allowing the children to inherit the full £1.3 million estate.
Estate planning presents unique challenges and opportunities for company directors, freelancers, and the self-employed. Your business is often your most significant asset, and its value can create a substantial IHT liability.
Relevant Life Policies & Executive Protection
While a standard Relevant Life Policy is a form of death-in-service benefit designed to protect an employee's family, the principles can be adapted. A business can, in certain circumstances, pay for a director's Whole of Life policy. This is known as an 'Executive Insurance Plan'. The premiums are typically treated as a business expense for the company and a P11D/Benefit-in-Kind for the director. While not directly saving tax, it's a way of funding personal estate planning through the business.
This is a complex area requiring specialist advice, as the tax treatment depends on the specifics of the arrangement. However, it's a powerful option for extracting value from a company to fund personal IHT planning.
Gift Inter Vivos Insurance
For business owners planning their succession, gifting company shares to the next generation is a common strategy. However, these gifts are considered 'Potentially Exempt Transfers' (PETs). If you die within seven years of making the gift, its value falls back into your estate for IHT purposes.
Gift Inter Vivos insurance is the perfect solution here. It's a specific type of term insurance policy designed to cover this tapering IHT liability. The policy amount reduces over the seven-year period in line with the tapering tax bill, providing a cost-effective safety net.
Key Person Insurance vs. IHT Planning
It's vital not to confuse personal IHT planning with business protection.

Like any financial product, Whole of Life insurance has both advantages and disadvantages. A balanced view is essential.
| Pros 👍 | Cons 👎 |
|---|---|
| Guaranteed Payout: A payout is certain, perfectly matching the certainty of an IHT bill on death. | Higher Cost: Premiums are significantly more expensive than term insurance. |
| Tax-Efficient: When written in trust, the payout is free from Inheritance Tax. | Lifelong Commitment: Premiums must be paid for the rest of your life. Failure to pay will cause the policy to lapse with no value. |
| Peace of Mind: Provides certainty that your IHT liability will be covered, protecting your family's inheritance. | Risk of Reviewable Premiums: If you choose a reviewable policy, premiums can become unaffordable in later life. |
| Quick Access to Funds: A trust bypasses probate, giving beneficiaries fast access to cash to pay the tax bill. | Inflexibility: The policy is designed for one purpose. Unlike an investment, you cannot access the cash for other needs. |
| Financial Discipline: The regular premium forces a disciplined approach to providing for a future tax bill. | Legislative Risk: IHT laws could change in the future, potentially reducing or eliminating the need for the cover. |
Whole of Life insurance is a cornerstone of IHT planning, but it works best as part of a wider strategy. Here are other methods to consider:
A well-rounded estate plan often combines several of these strategies. For example, you might use gifting to reduce the size of your estate over time, while a Whole of Life policy provides a backstop to cover the remaining liability.
Your health has a direct impact on your life insurance premiums. A healthier lifestyle, lower BMI, and being a non-smoker will always result in a more affordable policy. But beyond the financial benefits, investing in your health is about maximising your 'healthspan' – the number of years you live in good health.
