Direct answer: From 6 April 2026, Business Property Relief (BPR) and Agricultural Property Relief (APR) will no longer provide unlimited 100 percent inheritance tax relief. Full relief will be capped at £2.5 million per person, with any excess qualifying assets receiving only 50 percent relief, creating an effective 20 percent inheritance tax charge on the excess.
For couples, the allowance is transferable, giving a potential £5 million combined 100 percent relief, but estates above this level will face inheritance tax for the first time, often without sufficient cash to pay it.

What Are BPR and APR?
Business Property Relief (BPR) and Agricultural Property Relief (APR) are inheritance tax reliefs designed to allow trading businesses and farms to pass between generations without being broken up to pay tax.
APR applies to qualifying agricultural land, buildings, and in some cases farmhouses. BPR applies to qualifying trading businesses, including unlisted shares and interests in partnerships.
Until now, both reliefs could apply at 100 percent with no upper limit.
What Changes from 6 April 2026
From 6 April 2026:
- The first £2.5 million of combined qualifying BPR and APR assets per individual continues to receive 100 percent relief
- Any qualifying value above £2.5 million receives 50 percent relief
- The unused allowance transfers to a surviving spouse or civil partner
- This creates a maximum £5 million combined 100 percent relief for couples
- The excess above this level is exposed to inheritance tax at an effective 20 percent
This is a structural change. It introduces a permanent inheritance tax exposure for larger family businesses and farms, even where assets remain fully trading.
Worked Example: Single Business Owner
A family business is valued at £4 million and qualifies fully for BPR.
- £2.5 million at 100% relief = £0 tax
- £1.5 million at 50% relief leaves £750,000 taxable
- Inheritance tax at 40% on £750,000 = £300,000
Worked Example: Married Couple or Civil Partners
A jointly owned trading business and farm is valued at £6 million, fully qualifying for BPR and APR.
- Combined 100% relief available: £5 million
- Excess above allowance: £1 million
- 50% relief applied to excess leaves £500,000 taxable
- Inheritance tax at 40% = £200,000
Why This Matters for Family Businesses and Farms
Most family businesses and farms are asset rich but cash poor. The new rules mean:
- Inheritance tax may be due even where reliefs still apply
- Tax is triggered without a sale or break up of the business
- Borrowing or forced asset sales may be required
- Successors inherit a tax problem, not just an asset
Rising Values Mean More Families Affected Over Time
Rising land and business values mean more families will be caught over time, even if they are below the thresholds today. The £2.5 million cap is not index-linked.
Interaction with Other Inheritance Tax Rules
The BPR and APR caps sit alongside existing inheritance tax rules, including:
- Nil Rate Band of £325,000 per person
- Residence Nil Rate Band, subject to taper above £2 million estates
- Instalment payment rules for qualifying assets (up to 10 years)
- Anti-forestalling provisions for certain lifetime transfers
For many estates, the combined effect is a larger and earlier inheritance tax exposure than expected.

The change shifts planning away from pure relief reliance and toward liquidity planning.
Common responses include:
- Reviewing ownership structures and qualifying status
- Lifetime gifting strategies, where appropriate
- Trust planning in specialist cases
- Creating guaranteed liquidity to meet inheritance tax without asset sales
For many families, insurance-based liquidity planning becomes the most practical solution because it provides certainty without disrupting ownership or control.
Why Accurate Modelling Matters
Many online calculators and commentary still assume unlimited BPR and APR. That assumption will be wrong from April 2026.
Accurate modelling allows families to:
- Quantify the real exposure
- Decide whether planning is proportionate
- Assess whether liquidity solutions are affordable before underwriting
