Agricultural Property Relief and Business Property Relief for farms

Agricultural Property Relief (APR) and Business Property Relief (BPR) can significantly reduce or eliminate the inheritance tax due when a farm passes between generations. However, 100% relief is capped at a combined threshold per person, meaning larger estates may face a tax liability.

This guide helps you understand how APR and BPR work for farms, assess your exposure, and plan your next steps.

How APR and BPR relief works

Qualifying agricultural property and business assets can receive 100% relief from inheritance tax up to a combined allowance of £2.5 million per person.

Above this allowance, relief reduces to 50%. This means an effective inheritance tax rate of 20% on the excess value (half the standard 40% rate).

These rules took effect on 6 April 2026 under the Finance Act 2026 (section 65 and Schedule 12). The allowance was raised from the originally announced £1 million to £2.5 million on 23 December 2025. It is frozen at that level initially, then indexed to CPI from 6 April 2031.

Agricultural Property Relief (APR) thresholds

Business Property Relief (BPR) thresholds

For farms, BPR covers business trading assets that do not qualify for APR. This typically includes machinery, livestock, harvested crops, and trading stock.

Key points about the combined allowance

The £2.5 million allowance applies to APR and BPR combined. You cannot claim £2.5 million for APR and another £2.5 million for BPR. The total across both reliefs is £2.5 million per person.

The allowance is fully transferable between spouses and civil partners, in the same way as the nil-rate band. This means a couple can pass on up to £5 million in qualifying agricultural and business assets with 100% relief. Where the first death occurred before 6 April 2026, the full £2.5 million allowance is treated as available to transfer to the estate of the surviving spouse or civil partner.

These allowances are in addition to the standard nil-rate bands (£325,000 per person, plus the £175,000 residence nil-rate band if passing a home to direct descendants - although the residence nil-rate band is tapered by £1 for every £2 of estate value over £2 million, so it is rarely available to larger farming estates). A farming couple could therefore potentially pass on more than £5.6 million tax-free in total.

What property qualifies for APR

APR applies to the agricultural value of qualifying property. This is the value the property would have if it could only be used for agriculture. For land with development potential, the agricultural value may be significantly less than market value.

Qualifying agricultural property includes:

• Agricultural land and pasture
• Woodland and land used for timber if part of a farming operation
• Farm buildings used for farming purposes (barns, grain stores, livestock housing)
• Farmhouses - but only if occupied for the purposes of agriculture
• Cottages and buildings occupied by farm workers

The farmhouse question

Farmhouses are a common area of dispute with HMRC. To qualify for APR, the farmhouse must be:

• Occupied by someone actively involved in farming the land
• Of a character appropriate to the agricultural land
• Proportionate in value to the farm (HMRC often challenges farmhouses worth more than the farming land and buildings)

A farmhouse used as a retirement home after the farmer stops working, or one that has been substantially extended beyond agricultural needs, may not qualify for APR.

Environmental land management agreements

APR has been extended to land subject to certain environmental land management agreements (such as SFI and Countryside Stewardship). This means land taken out of agricultural production for environmental purposes may still qualify for APR, protecting farmers who participate in agri-environment schemes.

What assets qualify for BPR

BPR covers business assets used in the farming trade that are not agricultural property. For farms, this typically includes:

• Tractors, combine harvesters, and other machinery
• Livestock (breeding stock and trading animals)
• Harvested crops and grain in store
• Trading stock (feed, seed, fertiliser)
• Partnership interests in a farming partnership
• Shares in a family farming company

Important exclusions

Some assets do not qualify for BPR:

• Investment assets (property let to third parties)
• Holiday let cottages (treated as investment, not trading)
• Land let out under grazing licences or farm business tenancies (may qualify for APR instead if agricultural)
• Excepted assets - assets not used in the business

Ownership and occupation periods

To qualify for BPR, the asset must have been owned by the deceased for at least 2 years before death. For APR, the property must have been occupied by the owner for agricultural purposes for 2 years, or owned for 7 years while occupied by someone else (such as a tenant) for agriculture throughout. For inherited property, the previous owner's period of ownership can count if they also qualified for the relief.

AIM shares

Shares listed on AIM (Alternative Investment Market) only receive 50% BPR relief. This affects farming companies whose shares are traded on AIM.

How to calculate your potential IHT liability

To understand your exposure, estimate your total estate value and how it splits between APR-qualifying, BPR-qualifying, and non-qualifying assets.

Step 1: Get a current valuation

Instruct a qualified agricultural valuer (RICS or CAAV member) to value:

• Agricultural land and buildings at agricultural value
• The farmhouse (with and without APR)
• Machinery and livestock
• Non-agricultural assets (diversified businesses, let property)

Step 2: Categorise your assets

Step 3: Calculate liability - worked example

Example: a farm worth £4 million owned by one person

• APR/BPR qualifying assets: £3.5 million
• First £2.5 million: 100% relief = no IHT
• Remaining £1 million of qualifying assets: 50% relief = £200,000 IHT (40% on the unrelieved £500,000)
• Non-qualifying assets: £500,000 - the nil-rate band (£325,000) leaves £175,000 taxable at 40% = £70,000. The residence nil-rate band is not available because it is tapered by £1 for every £2 of estate value over £2 million, and is lost entirely above £2.35 million
• Total IHT: £270,000

The same farm owned by a married couple: with the fully transferable allowance, the couple has £5 million of combined 100% relief. The £3.5 million of qualifying assets are fully relieved, and the £500,000 of non-qualifying assets are covered by the two nil-rate bands (£650,000 combined). No inheritance tax is due.

Without APR/BPR relief: the same estate would face significantly higher inheritance tax (100% of value above nil-rate bands at 40%).

Payment options if IHT is due

If inheritance tax is due on agricultural or business property, the estate can pay in instalments rather than finding the full amount immediately.

This payment option may make it possible to pay IHT from farm income without selling land. However, you need to model whether the farm can generate sufficient cash flow to meet the annual instalments.

Action steps for succession planning

Farmers should take a proactive approach to inheritance tax planning:

When to seek professional advice

This guidance provides an overview, but inheritance tax planning for farms is complex. Seek professional advice if:

• Your farm is worth more than £2.5 million
• You have diversified income streams (holiday lets, renewables, contracting)
• Your farmhouse is a significant proportion of the total value
• You are considering lifetime gifts or restructuring
• You have children or successors with different interests
• You want to retire but remain living in the farmhouse

Who can help

• Solicitor - for will drafting and legal structures
• Accountant or tax adviser - for tax calculations and planning
• Agricultural valuer (RICS/CAAV) - for asset valuations
• Financial adviser - for insurance and investment options

Look for professionals with specific agricultural experience. The sector has unique rules that generalists may not understand fully.
