## Background on IHT Relief Changes
From **6 April 2026**, the UK government has capped **Agricultural Property Relief (APR)** and **Business Property Relief (BPR)** so that combined value eligible for **100% relief** is limited to **£2.5 million per person** (£5 million for couples). Above this threshold, relief drops to **50%**, leading to an effective Inheritance Tax rate of **20%** on excess value.

Trust holdings and properties listed on AIM are also affected with specific restrictions and reduced BPR/APR relief above value thresholds. ([tax.org.uk](https://www.tax.org.uk/new-tax-year-new-rules-what-s-changing-this-april?utm_source=openai))
## Case Scenario: The Farm Owned by Mr & Mrs Green
| Farmer | Asset | Ownership Structure | Value | Relief Before April 2026 | Relief From April 2026 |
|--------|--------|-----------------------|--------|----------------------------|--------------------------|
| Mr & Mrs Green | Family farm including land, barn, machinery, property | Joint ownership under trusts | £4 million (per person £2 million) | Previously full APR/BPR on all £4 million | Full relief on first £2.5 million each; 50% relief on remaining £1.5 million (much smaller tax saving) |
Without planning, excess value (>£2.5M each) will have only 50% relief, so a portion of assets will face a 20% IHT rate on untaxed value. For example, £1.5M excess leads to £300,000 charge for each. Combined, for Mr & Mrs Green this could result in ~£600,000 liability.
## Mitigation & Planning Strategies
- **Gifting assets during lifetime**, either outright or via trusts, especially before death, to reduce value of relief-eligible estate.
- **Transferring ownership** or splitting ownership among spouses to utilize the full relief limit per person.
- **Using AIM-listed shares**: note that shares listed on Alternative Investment Market are limited to **50% relief regardless of value**, so be cautious.
- **Trust structures** may defer reliefs—consider timing and trust types carefully.
- **Insurance policies**: consider IHT insurance to cover potential tax liability based on current farm value.
## Payments, Deadlines & Compliance
- IHT is payable from estate at death; executors must prepare IHT return including details of qualifying property and relief claims.
- Where assets are in trusts or jointly held, include documents showing ownership and relief eligibility.
- Valuations should be up to date and reflect market values as of date of death.
## Key Takeaways
- The cap means **full relief only for £2.5 million per person GBP of APR/BPR-qualifying asset value**; the rest faces 50% relief.
- Planning early is essential—transfers and restructuring must be established well before date of death.
- Particularly relevant for those with sizeable farming business, land holdings, or high-value business assets.
- Legal and tax advice is crucial, especially when dealing with trusts or shares listed on specific markets.
**Conclusion**: The April 2026 capping of IHT reliefs marks a material shift in how business and farming estates will be taxed upon death. Proactive ownership planning, valuation updates, and structuring ownership across spouses can soften the blow.
