Why “Deathbed” Inheritance Tax Planning Often Fails – And What You Should Do Instead
When someone is approaching the end of their life, it’s natural to consider how to pass wealth on to loved ones efficiently. While some inheritance tax (IHT) planning can be done late in life, relying on last-minute strategies—especially involving Business Property Relief (BPR)—can often backfire.
At Merranti Accounting, we always advise clients to plan early, and the issue of “deathbed” planning is a perfect example of why. In this article, we’ll explain why relying on last-minute BPR strategies is risky, how the two-year ownership rule works, and where recent legal cases have highlighted costly mistakes.
What Is Business Property Relief (BPR)?
BPR is one of the most valuable reliefs in the IHT system. It allows qualifying business assets to be passed on free of inheritance tax—either at 100% or 50%, depending on the nature of the asset.
Assets that may qualify include:
- Shares in unquoted trading companies (100%)
- Ownership of a business (100%)
- Land or buildings used in a business (50%)
- Shares in quoted companies (in limited situations)
BPR exists to protect trading businesses from being broken up to pay tax bills when the owner dies. However, it comes with important conditions—especially around ownership period and business activity.
The Two-Year Ownership Rule
One of the key conditions of BPR is that the individual must have owned the relevant business property for at least two years before it is transferred (typically on death).
✅ If the business property has been owned for less than two years, BPR is not available—with limited exceptions.
Can You “Buy Into” BPR Shortly Before Death?
Many people (and sometimes advisers) mistakenly believe they can subscribe for shares in a trading company shortly before death, claim BPR on the value, and avoid IHT. Unfortunately, this approach is flawed—unless very strict criteria are met.
Let’s look at two real-world cases that illustrate what can go wrong.
⚖️ Case Study 1: Executors of Dugan-Chapman v HMRC (2008)
In this case, the deceased (MDC) subscribed for 1 million shares in a company just two days before her death.
The executors argued that these shares should qualify for BPR under the “replacement property” rule. HMRC rejected the claim, stating it was a new share subscription, not linked to previously owned shares. There was insufficient evidence to prove it was a rights issue connected to earlier holdings.
✅ However, 300,000 shares acquired six days before death under a documented rights issue (in exchange for a £300,000 loan account) did qualify for BPR.
Key lesson: Documentation is crucial. If you intend to convert loans into shares, it must be done through a formal rights issue and supported with the proper paperwork.
⚖️ Case Study 2: Cook, The Executors of The Estate of v HMRC [2025]
In this case, WC died in 2016 and had subscribed to 242,192 shares via a rights issue just three months before death, converting a loan of £675,000.
HMRC denied BPR on these new shares, claiming they were not linked to shares held for two years. More importantly, the executors submitted their appeal late, and the case was rejected on that basis alone.
Key lesson: Even if you’re right on the facts, procedural errors can cost you. Timely submissions and professional handling are essential.
What About Replacement Property Rules?
There are some exceptions to the two-year rule. If replacement property is acquired, the ownership period can be combined with the previous asset, provided:
- Both assetscent occurred immediately or soon after disposing of the original
This is most relevant when someone sells one business and buys into another. But again, clear evidence and correct process are key.
Hidden Risk: Excepted Assets
Even if BPR appears to apply, HMRC can still deny relief on part of the value if the company holds assets not required for its trading purposes.
This includes:
- Excess cash
- Investment property
- Art, vehicles, or other luxury items
🛑 For BPR to apply, the company must have a genuine business need for the cash raised from a share issue.
If the shares are simply issued to convert cash (e.g., from a loan account) into shares for BPR purposes—but there’s no intention to use the cash in the business—HMRC may argue the cash is an “excepted asset”, and exclude it from BPR.
Why “Deathbed” Planning Is Problematic
There are several reasons why last-minute IHT planning, especially with BPR, is risky:
| Risk | Explanation |
|---|---|
| Ownership period | Two-year rule must be met, or relief is lost |
| Documentation | Lack of clear paperwork can invalidate claims |
| Company use of funds | If the business doesn’t need the cash, HMRC can exclude it |
| Procedural delays | Late appeals or incomplete forms can cost the relief |
| Stress and timing | Families may not have time or clarity to make complex decisions near death |
What Should You Do Instead?
-
Start planning early – The earlier you begin IHT planning, the more options are available.
-
Structure shareholdings strategically – Ensure shares are issued through proper channels, and that the business has a real use for any capital raised.
-
Document everything – HMRC looks closely at intent and evidence. Keep clear records of rights issues, loan conversions, and business decisions.
-
Review company structure – Regularly assess whether the business meets BPR criteria (e.g., trading activity, asset use).
-
Get advice – Inheritance tax rules are complex. Always involve professionals in planning and execution.
Final Thoughts
BPR is a powerful tool for business owners to pass on wealth without a heavy tax burden—but it’s not something that can be relied on at the last minute. As the cases above show, even a two-day or six-day gap can mean the difference between full relief and a denied claim.
If you or your loved ones are considering inheritance planning involving a business, don’t wait. Start the conversation now—because when it comes to tax and the taxman, it’s always better to be early than late.
