Business Property Relief: What Company Directors Need to Know
Business Property Relief (BPR) can protect your trading company's shares and assets from the 40% Inheritance Tax charge - but only when your business qualifies as a trading company in HMRC's eyes. Retained profits and surplus cash held in the trading company are among the most common reasons directors lose that qualification without realising it.

What is Business Property Relief?
BPR was introduced to protect trading businesses from Inheritance Tax at the point of succession. When your company qualifies, shares and qualifying business assets can pass to your heirs at up to 100% IHT relief - meaning no Inheritance Tax charge on those assets.
To qualify, a business must be primarily a trading company, not an investment company. HMRC has the power to reclassify a business as an investment company if it holds too much cash or too many non-trading assets relative to its trading activity - and that reclassification can happen without any deliberate action on your part.
The relief has been available since 1976 and remains one of the most powerful estate planning tools in existence - but only where the underlying business structure supports it.
How directors inadvertently lose BPR
There are two separate mechanisms by which a company can lose BPR, and most directors are unaware of either until it is too late.
The trading company test
HMRC requires your company to be wholly or mainly a trading company. Once investment assets or investment-type activity approaches 20% of the business, HMRC's view of your company begins to change. Cross 50% and BPR is lost entirely. A business can drift from qualifying trading company to investment company status without anyone noticing.
The excepted assets rule
Even where a company passes the overall trading company test, specific assets can be excluded from BPR. HMRC calls these “excepted assets” - and surplus cash is the most common example.
If your company holds retained profits that are not demonstrably needed for the day-to-day operation of the business, HMRC can exclude that cash from BPR relief. This is not a future risk - it applies to your current balance sheet. HMRC will not accept a general “rainy day fund” as a business need. Everything above what the business actively needs to trade is at risk.
The 2026 changes - and the risk already here
The immediate risk: surplus cash
Most directors focus on the new £2.5 million cap when they hear about BPR changes. But for the company directors TLPI works with, the more immediate concern is one that has always existed and is routinely overlooked: surplus cash sitting in the trading company.
Under HMRC’s excepted assets rules, retained profits not demonstrably needed for day-to-day trading can be excluded from BPR right now. At the point of transfer, HMRC reviews the balance sheet and strips out any cash it considers surplus. That cash then faces the full 40% Inheritance Tax charge.
Many directors hold significant retained profits for entirely sensible reasons. HMRC does not consider these trading requirements. This risk is already affecting directors today - not at some future trigger point.
The April 2026 cap
From April 2026, BPR is capped at £2.5 million at 100% relief. Assets above that threshold receive 50% relief, creating an effective 20% Inheritance Tax rate on the excess. This is a secondary concern if surplus cash has already undermined the BPR qualification on those assets.
Both risks - the excepted assets problem and the cap - can be addressed by moving surplus profits out of the trading company into a properly structured vehicle before the point of transfer.
April 2027: why pension planning is changing
From 6 April 2027, unused pension funds - including SSAS pension schemes - will form part of your estate for Inheritance Tax purposes.
Previously, money held within a SSAS could pass to beneficiaries outside the IHT estate. From April 2027, it will not. Business Property Relief does not apply to pension assets, so the rationale that made pension accumulation attractive from an IHT perspective changes fundamentally.
For directors who have been building pension wealth with an IHT objective in mind, the position needs to be reviewed before April 2027. A Family Investment Company - or a combined SSAS and FIC structure - may offer a more appropriate strategy once pension assets enter the taxable estate.
TLPI does not position a SSAS as an Inheritance Tax planning vehicle. Its primary value remains Corporation Tax reduction and pension investment control.

Why this may not have come up with your accountant
Most company directors rely on their accountant for tax advice, and rightly so. Accountants are essential for annual compliance, tax returns, and year-to-year financial management.
However, BPR planning is not a compliance exercise. It requires structural decisions about how the company holds assets, what legal vehicles are in place for wealth transfer, and how those structures interact with HMRC’s trading company tests over time. These decisions sit outside the scope of a standard annual accounts review.
Accountants are focused, quite correctly, on this year’s numbers. The 5-year and 10-year structural planning that preserves BPR and plans for succession is a different discipline - one that many general practice accountants do not routinely address for business clients.
TLPI works alongside accountants, not in competition with them. Where an accountant refers a client to us, we are glad to work directly with that accountant to ensure the structures we put in place are properly understood and supported.
How TLPI protects your Business Property Relief
TLPI is a specialist tax planning firm working exclusively with UK company directors. We establish and administer the legal structures that protect BPR, reduce Corporation Tax, and plan for succession in a tax-efficient way.
Family Investment Company (FIC)
A FIC moves surplus cash out of the trading company into a separate legal structure that you continue to control. The cash is no longer an excepted asset within the trading company, directly addressing the BPR risk on retained profits. The trading company is left as a clean qualifying trading business - which is precisely what HMRC requires. TLPI establishes and administers FICs for company directors at the point where retained profits are creating BPR exposure.
Small Self-Administered Scheme (SSAS)
A SSAS reduces Corporation Tax - pension contributions are a legitimate business expense, deductible against Corporation Tax at 25%. A SSAS also allows the purchase of commercial property and places you as trustee in direct control of the scheme. Note: from April 2027, SSAS assets will enter the IHT estate.
Lifetime Business Tax Plan (LBTP)
The LBTP combines a SSAS and a FIC into a single integrated structure - addressing the BPR risk through the FIC and the Corporation Tax burden through the SSAS. For directors facing both challenges, it is typically the most complete approach available.
Integrated Planning: Combining SSAS and FIC
When a FIC and a SSAS are combined as part of a Lifetime Business Tax Plan, the two structures work together:
- The FIC holds surplus cash and investment assets, removing them from the trading company and protecting BPR qualification.
- The SSAS redirects Corporation Tax into a pension fund the director controls, with the option to purchase commercial property, make loanback to the business, and consolidate existing pension pots.
- Together, they address both the estate planning and the Corporation Tax burden - without either structure having to do a job it was not designed for.
