## Overview of the New Reliefs from 6 April 2026
- **Business & Agricultural Property Reliefs** combined allowance fixed at **£1 million** for the first portion eligible for **100% relief**, with any excess receiving **50% relief**.

- Transferability of the 100% rate between spouses or civil partners – useful where property or business assets are held in trust or jointly.

- Changes apply to **trust exit charges**, **gifts to charities**, and **gifts on death**, especially for UK agricultural property and overseas investors.

## Why This Matters: Implications for Estate Planning
- **Taxable value shift**: Assets beyond the £1 million allowance now face **50% relief**, impacting planning structures for estates that previously maximised 100% relief across their asset base.
- **Cross-border trusts and non-UK resident owners**: The revised rules target offshore structures and overseas owners, reducing some reliefs and increasing IHT risk.

## Examples of Impact
- *The Carter Family Farm*: Prior to April 2026, all agricultural land (~£1.8m) would benefit from 100% relief via Business Property Relief, but under the new rules only £1m is fully relieved; the remaining £800,000 gets 50% relief, increasing IHT owed significantly.
- *Lucy*, an overseas investor owning UK agricultural land via an offshore entity: trusts and reliefs available may be curtailed, as the government closes loopholes for overseas investors in UK agricultural property.

## Actionable Strategies
- Review **current estate plans**: estates sitting close to or beyond the £1 million level may need restructuring, possibly via lifetime gifting, use of trusts, or adjusting ownership between spouses to use both allowances.
- **Trusts audit**: check whether trusts are currently benefiting under old rules, especially those with assets in agricultural property; plan exits or transformations before 6 April 2026.
- **Update wills and ownership structures**: with transferability of allowances, spouses can share reliefs but only if wills and titles align correctly.
## Estate Planning Checklist
| Step | Action |
|------|---------|
| 1 | List all agricultural and business property assets held individually, jointly, or in trusts |
| 2 | Estimate their combined value; earmark which portion will likely surpass £1 million |
| 3 | Consult advisers to adjust ownership or gift parts before relief changes take effect |
| 4 | Ensure tax filings and trusts are correctly structured before the effective date |
## Final Thought
If you hold or plan to hold significant business or agricultural property, **these reforms demand attention now**. Minimising IHT exposure properly could save estates hundreds of thousands of pounds. Early and informed planning is your best safeguard.
