From April 2026, major changes to UK Inheritance Tax (IHT) rules have come into force—particularly affecting business owners and those with valuable assets. While this may sound like a niche topic, it’s highly relevant for many small and family-run businesses, especially those thinking about long-term succession planning.
Here’s a clear, practical breakdown of what’s changed and what it means for you.
What’s Changed in 2026?
The biggest change is to two key reliefs:
Business Property Relief (BPR)
Agricultural Property Relief (APR)
Previously, these reliefs could allow up to 100% of qualifying business assets to pass on tax-free, often meaning no Inheritance Tax at all.
👉 From 6 April 2026, that unlimited relief has ended.
The New £2.5 Million Limit
Under the new rules:
The first £2.5 million of qualifying business and agricultural assets can still receive 100% relief (no IHT)
Any value above £2.5 million only gets 50% relief
This effectively creates a 20% inheritance tax charge on the excess (half of the standard 40% rate)
For married couples or civil partners, allowances can be combined—meaning up to £5 million may pass tax-free
Why This Matters for Small Business Owners
Even if your business isn’t worth millions today, this change is still important because:
1. Growth Can Push You Into Scope
Many small businesses increase in value over time. What seems modest now could exceed thresholds later—especially if property or assets are involved.
2. Family Businesses Are Most Affected
These rules are particularly relevant if you plan to:
Pass your business to children
Keep it within the family
Build long-term wealth rather than sell
Previously, this could often be done tax-free. Now, that’s not always the case.
3. More Estates Will Pay Tax
While many smaller estates won’t be affected, the government expects some business-owning estates to face higher IHT bills from 2026 onwards
A Simple Example
Let’s say:
Your business is worth £3.5 million
£2.5 million = tax-free
Remaining £1 million = taxed at an effective 20%
👉 That’s a potential £200,000 tax bill
This is a significant shift from previous rules, where the full amount may have been exempt.
What Should You Be Doing Now?
These changes don’t mean panic—but they do mean planning is more important than ever.
Review Your Business Value
Understand roughly what your business is worth today—and what it could be worth in the future.
Start Succession Planning Early
Think about:
Who will take over the business
When ownership might transfer
Whether gradual transfers make sense
Consider Gifting Strategies
In some cases, passing assets during your lifetime can reduce tax—but timing and rules (like the 7-year rule) are critical.
Review Your Will and Structure
Ensure your will, ownership structure, and business setup are aligned with your long-term plans.
Get Professional Advice
These rules are complex, and small changes can have big tax implications. Getting tailored advice is key.
Are There Any Positives?
It’s not all bad news:
The £2.5 million threshold is higher than originally proposed (earlier plans suggested £1 million)
Many smaller businesses will still fall below the threshold
Spouses can combine allowances, which helps family planning
Final Thoughts
The 2026 Inheritance Tax changes mark a significant shift—particularly for business owners who have relied on full relief in the past.
The key takeaway is simple:
👉 If you own a business and want to pass it on, planning ahead is no longer optional—it’s essential.
Even if these changes don’t affect you today, they could in the future as your business grows.
Need Help Planning Ahead?
If you’re unsure how these changes affect your business—or want to put a clear plan in place—getting professional advice can help you protect what you’ve built and pass it on as efficiently as possible.
Proactive planning now could save your family a substantial tax bill later.
