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. (gov.uk)
- Transferability of the 100% rate between spouses or civil partners – useful where property or business assets are held in trust or jointly. (gov.uk)
- Changes apply to trust exit charges, gifts to charities, and gifts on death, especially for UK agricultural property and overseas investors. (gov.uk)
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. (assets.publishing.service.gov.uk)
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. (gov.uk)
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.
