Key BPR Facts for This Scenario
The Situation
Michael (65) owns a manufacturing business he built over 35 years. His estate includes:
| Family business | £2,500,000 |
| Main residence | £600,000 |
| Savings and investments | £300,000 |
| Pension | £200,000 |
| Total estate | £3,600,000 |
(Note: from April 2027, unused pension funds will be included in the taxable estate — this would add £200,000 to Michael's estate under the new rules)
Michael wants to pass the business to his daughter who works in the company, while ensuring his son (who works elsewhere) receives fair treatment.
Michael's business is valued at exactly £2,500,000 — sitting precisely at the April 2026 BPR cap. Under the new rules, the first £2,500,000 of combined APR and BPR qualifying assets still attracts 100% relief. Had the business been worth £3,500,000, the excess £1,000,000 would attract 50% relief — an additional £200,000 IHT liability.
Without Business Property Relief
If the business didn't qualify for relief:
| Estate value | £3,600,000 |
| Nil-rate band | −£325,000 |
| RNRB | £0 (tapered away — estate over £2M) |
| Total allowances | −£325,000 |
| Taxable estate | £3,275,000 |
| IHT due (40%) | £1,310,000 |
The RNRB is fully tapered away because Michael's net estate exceeds £2,350,000 — the point at which a single person loses all RNRB entitlement.
This would likely force the sale of the business to pay the tax bill.
Business Property Relief Applied
Fortunately, the business qualifies for 100% BPR as a trading company:
| Business value: £2,500,000 (100% relief) | £0 taxable |
| Other assets | £1,100,000 |
| Nil-rate band | −£325,000 |
| RNRB | £0 (still tapered away) |
| Taxable estate | £775,000 |
| IHT due (40%) | £310,000 |
| Tax saved by BPR | £1,000,000 |
These figures apply under the April 2026 rules. Under the pre-2026 rules the result was identical in this scenario because the business value happens to equal the new £2.5M allowance. For businesses valued above £2.5M, the post-2026 position is materially worse — see the worked example in our Business Relief guide.
Additional Planning Steps
To further optimise and ensure fairness between Michael's children:
| Planning step | Purpose | Key consideration |
|---|---|---|
| Will structure | Business to daughter, other assets to son | Ensure the will is professionally drafted to clearly separate business and non-business assets |
| Life insurance in trust | £400,000 policy to equalise inheritance and cover IHT | Must be written in trust — otherwise the payout joins the estate and increases the IHT bill |
| Pension nominations | Both children named equally (£100,000 each) | Review nominations annually; from April 2027 pensions will be included in the taxable estate |
| Gradual share transfer | Transfer shares to daughter over time | Gifts of unquoted shares may qualify as PETs — combined with BPR, careful structuring can reduce the estate further |
| Cross-option agreement | Allows daughter to purchase business at fair value | Protects business continuity if Michael’s estate needs liquidity; should be reviewed with a solicitor |
BPR Requirements Checklist
To qualify for business property relief, several conditions must be met. Here is how Michael's situation stacks up:
| Requirement | Status in this scenario |
|---|---|
| Trading business (not primarily investment) | Qualifying — manufacturing business |
| Owned for at least 2 years | Qualifying — 35 years’ ownership |
| Business actively trading at date of death | Qualifying — ongoing operations |
| Not subject to a binding sale contract | Qualifying — no sale agreement in place |
| No excepted assets issue (excess cash/investments) | Assumed qualifying — no significant non-trading assets noted |
| Within £2.5M combined APR/BPR allowance (April 2026) | Qualifying — business exactly at the cap |
How the April 2026 Reforms Affect This Scenario
Michael's scenario is instructive precisely because his business sits at the £2.5M threshold. For business owners in a similar position, the April 2026 reforms have no practical impact — 100% BPR continues to apply in full.
However, three groups face materially worse outcomes under the new rules:
| Affected group | Impact |
|---|---|
| Family businesses valued above £2.5M | The excess above the cap attracts 50% relief rather than 100%, creating a real IHT liability where previously there was none. A business worth £5,000,000 now generates £500,000 of IHT that would previously have been zero. |
| AIM share investors | Relief reduced from 100% to 50% regardless of portfolio size, making the effective IHT rate 20% rather than 0%. |
| Mixed APR/BPR estates (farmers with business interests) | The £2.5M allowance is shared, not separate. A farmer with £2,000,000 of agricultural property and £1,500,000 of business assets has only £500,000 of combined allowance remaining for the business, with 50% relief above. |
Key Takeaways
| Takeaway | Detail |
|---|---|
| BPR prevents forced business sales | Without relief, a £2.5M business could generate a £1M+ IHT bill payable within 6 months of death |
| 100% relief applies up to £2.5M (April 2026) | Businesses within this cap are unaffected by the reform |
| No seven-year rule | Unlike lifetime gifts, BPR applies regardless of how long before death the asset was acquired (subject to the two-year minimum) |
| Life insurance in trust is essential | For any residual IHT liability, a policy written in trust provides liquidity without increasing the estate |
| Fair treatment requires planning | Non-business children need separate provision — the business itself should not be split to achieve fairness |
| Annual review is critical | Business value, trading status, and asset mix change — BPR qualification should be reviewed regularly with a specialist |
Frequently Asked Questions
Does my family business automatically qualify for BPR?
Not automatically. BPR requires the business to be a qualifying trading business (not primarily an investment business), owned for at least two years, and still actively trading at the date of death. HMRC scrutinises claims carefully, particularly where the business holds significant cash reserves or investment assets alongside trading activity. A specialist valuation and tax review is recommended for any business estate above the IHT threshold.
What if my children don’t want to take over the business?
BPR is not conditional on the business passing to a family member. The relief applies as long as the asset qualified at the date of death — the beneficiary can be anyone, including non-family members or a trust. However, the purpose of BPR is to preserve going-concern businesses. If the business is sold shortly after death, HMRC may in some circumstances challenge the relief. Planning for succession — including cross-option agreements if no family successor exists — is important.
How does the April 2026 reform affect small family businesses?
For most small family businesses with qualifying assets below £2,500,000, the reform has no practical impact. Full 100% BPR continues to apply. The changes affect larger businesses (above the £2.5M cap), AIM share investors (relief cut from 100% to 50%), and mixed APR/BPR estates where agricultural and business assets together exceed £2.5M.
Can I transfer shares in my business to my children now to reduce IHT?
Yes. Gifts of shares in qualifying unquoted trading companies are potentially exempt transfers (PETs) — they fall out of the estate if you survive seven years. Additionally, shares transferred during your lifetime that qualified for BPR at the time of transfer may benefit from BPR on the PET calculation if you die within seven years. Transferring shares early can also reduce the estate’s exposure to the £2.5M cap by spreading ownership. Specialist advice is essential — getting this wrong can create unexpected tax liabilities.
Does life insurance help with business IHT planning?
Yes — a whole of life policy written in trust is one of the most practical tools for managing residual IHT on a business estate. The policy must be written in trust so that the payout does not join the estate (which would increase the IHT bill). The premium is typically treated as a gift out of normal expenditure if it meets the relevant conditions, meaning it does not use the annual gift exemption. The policy proceeds provide liquidity to pay the IHT bill without requiring the business or other assets to be sold.
