Around 40,000 families face an inheritance tax bill each year, and the figure is climbing. For anyone inheriting a property, the tax can land at 40% of the value above the tax-free allowance — a bill that often must be paid within six months of death, before probate is even granted. If the money isn’t sitting in savings, the property itself may need to be sold to cover it.

The rules around Inheritance Tax (IHT) are shifting faster than they have in years. From April 2025, the old domicile test is being replaced by a residence-based system. From April 2026, Agricultural and Business Property Relief faces a £1 million cap. And from April 2027, most unused pension funds will be pulled into the taxable estate. These changes mean that a will written even five years ago may no longer achieve what it was designed to do. The question is not whether your estate is affected, but how much. Here’s what you actually need to know.
Four things to understand about insuring inherited property
What I tend to notice is that most people understand the basic 40% rate. What catches them out is the timing — that six-month window, and the fact that the tax comes due before the estate can access the money locked up in the property. Insurance can bridge that gap, but only if it’s set up the right way. The difference between a policy written into trust and one that isn’t can be tens of thousands of pounds.
The 2026–2027 rate changes and what they cost in practice
The headline figures — £325,000 nil-rate band, £175,000 residence nil-rate band — are frozen until 2030, so they don’t move with inflation. That alone pulls more estates into the tax net each year as property values rise. But the bigger shock is coming from the three structural changes taking effect between 2025 and 2027.
The table below shows how the three main allowance bands stack up for different estate situations — and what the tax bill looks like for a typical property owner.

| Situation | Nil-rate band | Residence nil-rate band | Total allowance | Tax on £700,000 estate |
|---|---|---|---|---|
| Single person, leaving home to direct descendants | £325,000 | £175,000 | £500,000 | £80,000 |
| Single person, leaving home to non-descendants | £325,000 | £0 | £325,000 | £150,000 |
| Married couple (first death, full transfer to spouse) | £0 (transferred) | £0 (transferred) | £0 (deferred) | £0 |
| Married couple (second death, leaving to children) | £650,000 | £350,000 | £1,000,000 | £0 (within allowance) |
The practical takeaway: a single person with a £700,000 home could owe £80,000 in IHT. If they don’t have that cash, the property gets sold. That’s the risk insurance is designed to cover. A whole-of-life policy for the £80,000 amount, written into trust, means the payout arrives within weeks of death — well within the six-month payment window.
For business or farmland owners, the changes bite harder from April 2026. Agricultural Property Relief and Business Property Relief are both capped at £1 million combined, with anything above that getting only 50% relief. That £1 million cap is not transferable between spouses either — it applies to each estate individually.
Common mistakes that cost heirs tens of thousands
Assuming insurance payouts are automatically tax-free
A life insurance payout goes into your estate unless you write the policy into a trust. Without a trust, the payout adds to the estate value and can tip it over the nil-rate band, creating a fresh IHT bill on the very money meant to pay the tax. Writing the policy into a discretionary trust at inception keeps the payout outside the estate. The process is straightforward: your insurer or adviser provides a trust deed, you sign it alongside a witness, and the policy is held under the trust from day one. The trustees (you can be one of them) manage the payout on death for the beneficiaries you name.
Buying a reviewable policy to save on initial premiums
Reviewable whole-of-life policies start with lower premiums, but the insurer can increase them at each review — typically every five or ten years. For a policy taken out at age 60, premiums could double by age 75, exactly when income may be falling. A guaranteed whole-of-life policy has level premiums that never change. The difference might be £30–£50 a month early on, but over 25 years the guaranteed policy often costs less in total and removes the risk of the policy becoming unaffordable when it’s needed most.
Ignoring the pension inclusion from April 2027
Most people still think pensions sit outside IHT. From April 2027, that largely ends. If you have a £400,000 pension and a £500,000 home, your estate’s total value for IHT purposes could be £900,000 — well above the £500,000 single-person allowance. The tax on that estate would be £160,000. Without an insurance policy to cover the gap, the beneficiaries may have to draw down the pension with a large tax charge or sell the property. Reviewing your pension nomination forms and speaking to a financial adviser about whether a whole-of-life policy makes sense is the step most people skip.
Assuming the seven-year rule means no insurance needed
Gifting assets during your lifetime is a good IHT strategy — if you survive seven years, the gift falls outside your estate. But if you die inside seven years, the gift is clawed back into the estate and taxed at 40% on a sliding scale. A gift inter vivos policy (temporary life insurance) covers exactly this window. The sum insured decreases each year as the taper relief kicks in, so the premiums stay low. For someone gifting £200,000 to their children, a seven-year decreasing term policy might cost £30–£50 a month and avoids the risk that a missed seven-year window wipes out the benefit of the gift.
Setting up insurance to protect inherited property
Whole-of-life policies written into trust
This is the core strategy. You take out a whole-of-life insurance policy for the expected IHT bill — say £80,000 for a single person with a £700,000 estate. The policy is written into a discretionary trust from the start. On death, the trustees receive the payout directly, outside the estate, and can distribute it to the beneficiaries or use it to pay the IHT to HMRC. The property passes to the heirs without needing to be sold. The key numbers to check before buying: the level premium (guaranteed, not reviewable), the sum assured (does it cover the projected estate value after allowance), and the trust deed (does it name the right trustees and beneficiaries).
Joint life second death policies for couples
Because spouses can transfer assets between them free of IHT on first death, the tax only becomes payable on the second death. A joint life second death policy pays out only when both partners have died — which is when the money is needed. These policies cost significantly less than two individual whole-of-life policies because the insurer pays out once, not twice. For a couple in their 60s, the premiums might be 30–40% lower than two separate policies. The policy should still be written into a trust so the payout avoids the surviving partner’s estate.
Gift inter vivos policies for lifetime giving
If you’ve made significant gifts — helping children buy a home, passing down a business — a decreasing term policy covers the IHT risk during the seven-year window. The sum insured drops by roughly 14% each year, mirroring the taper relief. For a £200,000 gift, a policy starting at £80,000 (40% of the gift value) that decreases to zero over seven years would cost roughly £35–£60 a month depending on age and health. If you survive the seven years, the policy expires and you stop paying. If you die inside the window, the payout covers the IHT bill the beneficiaries otherwise would have to find.
The pension inclusion from April 2027 — what to do now
With unused pension funds entering the estate from 2027, anyone with significant pension savings should model their total estate value including the pension pot. For many, this will push the estate well above the nil-rate band for the first time. Options include: drawing down pension benefits earlier to gift the proceeds (starting the seven-year clock), nominating beneficiaries in a way that aligns with the estate plan, or taking out an additional whole-of-life policy specifically covering the pension-related IHT liability. The window for action is open now — once April 2027 arrives, the pension is in the estate regardless.

The £1.46 billion reason to revisit your estate plan now
The Treasury’s own figures project an extra £1.46 billion in IHT revenue by 2029–30, driven largely by the pension inclusion and the frozen allowances. That money comes from estates that currently plan around the old rules. The gap between what people think their estate is worth and what HMRC will count from 2027 is where the risk sits. A whole-of-life policy written into trust remains the most direct way to make sure inherited property stays with the people it was meant for, rather than being sold to settle a tax bill that insurance could have covered.
