Your possible objectives over the next 5–10 years:
Preserve 100% IHT relief where farmland and trading assets fit within the £2.5m combined APR/BPR allowance
Stack BPR on diversified trading income (farm shops, glamping, weddings) alongside APR on the core land
Capitalise on full expensing for farm machinery, buildings, and renewable energy installations

Working farmland is one of the UK's most tax-advantaged asset classes. It benefits from two overlapping reliefs: Agricultural Property Relief (APR) on the agricultural value of land and farmhouses, and Business Property Relief (BPR) on the trading assets. Together they can shelter the entire farm from inheritance tax where the land is farmed in-hand.
APR mechanics. Under IHTA 1984 ss.115–124C, APR provides up to 100% relief on the agricultural value of land and farmhouses. "Agricultural value" means the value the land would have if it could only be used for agriculture — often lower than market value, particularly for land with development potential. The relief applies if the land has been occupied for agricultural purposes for at least two years (owner-occupier) or owned for seven years and let to someone farming it (IHTA 1984 s.117).
BPR overlap. Farm machinery, livestock, and diversified trading income (farm shops, glamping pods, wedding venues) are not covered by APR but can qualify for 100% BPR as trading assets. The two reliefs stack: APR on the land, BPR on the trading business. This makes working farms significantly more tax-efficient than bare land held for investment.
The 2026 change. From 6 April 2026, APR and BPR are combined into a single £2,500,000 allowance at 100% relief. Above that threshold, relief drops to 50% (an effective 20% IHT rate on the excess, assuming the estate is otherwise taxable at 40%). This materially changes the calculus for larger farms and estates. A £5,000,000 qualifying farm estate would previously have qualified for full relief. Post-April 2026, £2,500,000 qualifies at 100%, with the remaining £2,500,000 at 50% relief — exposing £1,250,000 to IHT and creating a potential £500,000 liability before any other exemptions, spouse planning, or reliefs.
Capital allowances. Farm buildings, grain stores, slurry systems, milking parlours, and fixed equipment qualify for the same AIA (£1,000,000 per year) and full expensing (companies) treatment as any other trade. A working farm is, for capital allowances purposes, treated identically to any other business. The AIA is shared across all group companies, so multi-entity farm groups need to plan the timing of capital expenditure.
Diversification strategy. Many UK farms now run glamping sites, wedding venues, or farm shops alongside traditional farming. This diversified trading income can independently qualify for BPR and capital allowances, stacking with the core APR claim on the underlying land. The key is that the diversified activity must be genuinely trading rather than investment. HMRC applies the same trade-vs-investment test described in BIM55700–BIM55715. A wedding venue with active management, staff, and services is likely a trade. A barn let out for occasional events may be viewed as investment.
Ownership structure. Farms held personally benefit directly from APR and BPR at the individual level. Farms held within a company qualify for BPR on the shares if the company is a trading business, but APR on the underlying land does not apply through a company wrapper. This makes personal ownership or mixed structures common for farm families planning for succession.
Financing considerations. Farm mortgages are interest-only for many estates. Interest is fully deductible as a trading expense (unlike residential buy-to-let, which has been restricted to a 20% credit under s.24 ITTOIA 2005). This preserves the full tax shield on financing costs.
Risks and caveats.
Development land. APR only applies to agricultural value, not development value. Land with planning permission or strong development potential may see limited APR benefit.
Long tenancies. APR is weakened if the land is let on a long tenancy to a third party rather than farmed in-hand. HMRC IHTM24030 sets out the occupation requirements.
Succession timing. Lifetime gifting can preserve reliefs but must be done seven years before death to avoid a charge. The April 2026 reform has driven significant restructuring activity, especially for estates above the £2.5m 100% relief allowance.
Asset | Relief | Position from 6 April 2026 |
|---|---|---|
Agricultural land (APR) | Up to 100% on agricultural value | Shares the £2,500,000 combined APR/BPR 100% relief allowance |
Trading assets (BPR) | Up to 100% on business value | Shares the £2,500,000 combined APR/BPR 100% relief allowance |
Above £2,500,000 | 50% relief | Effective 20% IHT exposure on the excess if the estate is otherwise taxable at 40% |
For institutional investors. Direct farmland ownership is rare for PE and pension funds due to the long-horizon nature and succession complexities. More common is financing or partnership with farming families, where the investor provides capital for diversification projects (glamping, renewables) in exchange for a share of trading income that benefits from BPR and capital allowances. The £2.5m allowance means larger family estates still need liquidity planning, but the cliff is less severe than the originally trailed £1m figure.

Bottom line. Agricultural land remains a cornerstone of UK IHT planning, but the April 2026 reform changes the math. The opportunity lies in stacking diversified trading income (glamping, renewables, events) to maximise BPR while preserving APR on the core land. Professional advice is essential because the £2.5m allowance, spouse transfer rules, trusts, lifetime gifts, and valuation evidence can materially change the outcome.
