Why business owners must act before 20 March 2026 to secure valuable tax relief
⚠️ A major tax change is coming – and itโs being underestimated
From 6 April 2026, the government is fundamentally changing how Inheritance Tax (IHT) applies to business owners.
For years, trading businesses have benefited from 100% Business Relief (BR) – allowing many owners to pass their companies to the next generation free of inheritance tax.
That protection is now being restricted.
Under the new rules:
-
The first ยฃ1 million of qualifying business assets will continue to receive 100% relief
-
Any value above that will receive only 50% relief
This effectively introduces a 20% tax on business value above ยฃ1 million.
💥 What does this mean in real terms?
Letโs take a typical example:
-
Business value: ยฃ6 million
-
Under current rules: potentially ยฃ0 IHT
-
Under new rules:
-
ยฃ1m โ tax-free
-
ยฃ5m โ 50% taxable = ยฃ2.5m exposed
-
IHT at 40% = ยฃ1 million tax bill
-
👉 Thatโs ยฃ1 million lost to tax – often unnecessarily.
😴 The good news โ you still have a window to act
If you act before 6 April 2026, you can still use the current rules.
This means it is possible to:
-
Transfer shares into a discretionary trust
-
Lock in the existing 100% Business Relief
-
Avoid any immediate IHT
-
Defer any capital gains tax using hold-over relief
-
Remove future growth from your estate entirely
Done properly, this can protect significant value for your family.
⏳ Why the real deadline is 20 March 2026
Although the legislation changes on 6 April 2026, in practice:
👉 You cannot leave this until the last minute
To implement this planning correctly, we need time to:
-
Review your company structure
-
Confirm eligibility for Business Relief
-
Obtain a professional valuation
-
Draft and agree the trust documentation
-
Prepare CGT hold-over relief claims
-
Coordinate with solicitors
-
Execute the transfer properly
Thatโs why we are asking clients to contact us no later than 20 March 2026.
After that point, there may not be enough time to implement the planning safely and effectively.
🧠 How the planning works (in simple terms)
The most common strategy involves:
Step 1 โ Create a discretionary trust
A flexible structure allowing trustees to benefit your family.
Step 2 โ Transfer shares into the trust
Usually all or part of your trading company.
Step 3 โ Claim tax reliefs
-
Business Relief (IHT) โ no immediate inheritance tax
-
Hold-over relief (CGT) โ no immediate capital gains tax
Step 4 โ Future protection
-
The value transferred is outside your estate
-
Any future growth is also outside your estate
📊 Real-world outcomes
| Scenario | IHT at death |
|---|---|
| No planning (after April 2026) | ยฃ1.36 million |
| Partial planning | ~ยฃ960,000 |
| Full planning before April 2026 | ~ยฃ360,000 |
👉 Potential saving: ยฃ400,000 โ ยฃ1,000,000+
💰 What does it cost?
Typical implementation costs:
-
Valuation: ยฃ5,000 โ ยฃ10,000
-
Legal work: ยฃ4,000 โ ยฃ6,000
-
Tax and structuring: ยฃ3,000 โ ยฃ5,000
👉 Total: ยฃ10,000 โ ยฃ20,000
Compared to potential savings of ยฃ1 million+, this is one of the highest-return planning opportunities available.
⚠️ Important risks to understand
This is powerful planning โ but it must be done properly.
Key considerations include:
-
Ensuring the company qualifies as a trading business
-
Avoiding โgift with reservationโ issues
-
Proper valuation of shares
-
Correct execution of legal documentation
-
Submission of hold-over relief claims
-
Ongoing monitoring of Business Relief eligibility
This is not a DIY exercise โ it requires coordinated professional advice.
💬 A word from Jason Seagrave
โThis is one of the biggest planning opportunities Iโve seen in decades.
But itโs also one of the most time-sensitive.
If you act early, we can protect your business and potentially save your family over a million pounds in tax.
If you leave it too late, that opportunity is gone.โ
🕓 What you should do next
If you own a business worth more than ยฃ1 million:
👉 Do not wait
👉 Do not assume it wonโt affect you
Instead:
✅ Book a confidential strategy review
Weโll:
-
Assess your position
-
Estimate your potential saving
-
Explain your options clearly
💤 Final thought
Youโve spent years building your business.
With the right planning, you can ensure it benefits your family โ not the taxman.
