Agricultural Property Relief and probate: what farming families need to know
Agricultural Property Relief (APR) reduces the value of agricultural property for Inheritance Tax (IHT) purposes. For farming families and landowners, it is one of the most significant reliefs in the tax system. This article explains how APR works, who qualifies, how to claim it during probate, and what the reforms that took effect on 6 April 2026 mean for succession planning.
What is Agricultural Property Relief?
APR reduces the taxable value of agricultural property when calculating Inheritance Tax. It applies to the “agricultural value” of qualifying property: the value the land or buildings would have if they could only ever be used for agricultural purposes.
That figure is typically lower than the open market value. Any additional value, such as development potential, falls outside APR.
That does not always mean the extra value is taxed in full. Where the land is used in a working farming business, Business Property Relief may cover the balance. This matters most where land carries hope value for development. APR alone would leave that slice exposed, whereas a genuine trading farm may shelter it through BPR instead. The two reliefs now share one allowance, so model them together rather than separately.
HMRC sets out the qualifying conditions in detail in its guidance on Agricultural Relief for Inheritance Tax.
What property qualifies for APR?
Qualifying property includes farmland and pasture used to grow crops or rear animals, certain farm buildings, and farmhouses that are “character appropriate” to the agricultural operation. A farmhouse that is disproportionately large relative to the farm it serves may qualify only in part.
Environmental land management: From 6 April 2025, APR was extended to land managed under an environmental agreement with, or on behalf of, the UK government, devolved governments, public bodies, local authorities, or approved responsible bodies. This extension is now in effect. Many landowners had previously avoided entering environmental schemes for fear of losing APR, so the change is significant. Note, however, that the extension is limited to certain qualifying schemes, so not all environmentally managed land will automatically qualify.
Geographic scope: From 6 April 2024, APR no longer applies to agricultural property in the Channel Islands, Isle of Man, or the European Economic Area. Only property in the UK now qualifies.
Eligibility criteria for APR
APR is not automatic. Several conditions must be met before a claim can succeed.
Ownership and occupation period: The property must have been owned and occupied for agricultural purposes immediately before the transfer. The required period is two years where the owner (or a company they control, or their spouse or civil partner) occupies the land, and seven years where someone else, such as a tenant farmer, occupies it.
Active agricultural use: The land must be occupied for agricultural purposes or qualify under the environmental land management rules described above. Land left idle, or used primarily for amenity, may not satisfy the occupation requirement.
Two rules can rescue a claim that appears to fail the time test
Inherited land. If the deceased inherited the farm from someone else, their ownership period can include the earlier owner’s. Where the property came from a spouse or civil partner, the occupation period can be combined too. So a widow who inherited the farm last year may still satisfy a two-year test.
Replaced land. If agricultural property was sold and other agricultural property bought with the proceeds, the periods can be added together. The combined ownership must cover two out of the last five years, or seven out of the last ten where a tenant occupies. This helps farmers who have restructured or relocated.
Type of property: The property must be agricultural in nature. Farm equipment, machinery, and livestock do not qualify for APR, though they may qualify for Business Property Relief (BPR) instead.
Gifts of agricultural property made during a person’s lifetime can also qualify, subject to the same conditions applying at the relevant time.
One condition on lifetime gifts catches people out. If the donor dies within seven years, the relief only survives if the person who received the gift still owns the property and it still qualifies as agricultural. Sell the farm, or take it out of agricultural use, and the relief can be lost on the earlier gift. Anyone receiving farmland as a gift should understand that before making plans for it.
How the APR and BPR reform changed things from 6 April 2026
This is the most significant change to APR in decades. The reform became law when the Finance Act 2026 received Royal Assent on 18 March 2026. Section 65 and Schedule 12 of that Act make provision for the changes, as set out in the House of Commons Library briefing on the reforms. The government has also published a technical policy paper on changes to agricultural property relief and business property relief.
The old rules
Under the previous rules, qualifying assets attracted relief of up to 100% of their value from IHT, with no overall cap. A farm worth £5 million, £10 million, or more could pass entirely free of IHT, provided it met the qualifying conditions.
The new rules from 6 April 2026
From 6 April 2026, the maximum combined relief for 100% APR and BPR is capped at £2.5 million per individual. Any value above £2.5 million attracts 50% relief, producing an effective IHT rate of 20% on the excess.
In practice:
- The first £2.5 million of combined qualifying agricultural and business assets: 100% relief, no IHT payable.
- Value above £2.5 million: 50% relief, effective IHT rate of 20%.
APR and BPR share the same allowance
The £2.5 million cap applies to the combined value of assets attracting 100% APR and 100% BPR. If an estate includes both qualifying farmland and a qualifying business, the two count together towards the cap. Advisers must consider how each asset type sits within the combined figure.
AIM shares and the family farming company
The reform also changed the relief available on certain shareholdings, and the distinction matters.
From 6 April 2026, BPR falls from 100% to 50% on shares traded on a market of a recognised stock exchange but designated as not listed on it. The Alternative Investment Market (AIM) is the main example. The same 50% rate applies to qualifying shares on foreign exchanges that are not recognised stock exchanges.
This change does not affect shares in a genuinely private trading company. Where a farm runs through a family company whose shares are not traded on any exchange, those shares continue to be treated as ordinary qualifying business property, attracting 100% relief within the £2.5 million allowance.
Two points follow for farming families who also hold an AIM portfolio. First, the 50% rate applies to those shares whatever they are worth. Second, AIM shares do not draw on the £2.5 million allowance at all. An AIM holding therefore neither reduces the allowance available to the farmland nor benefits from it. The two should be modelled separately.
Transferable allowance for spouses and civil partners
Any unused portion of the £2.5 million allowance can transfer to a surviving spouse or civil partner. Where the first death occurred before 6 April 2026, the full £2.5 million allowance is still available for transfer.
As a result, a couple can pass on up to £5 million of agricultural or business assets between them, in addition to existing allowances such as the nil-rate band.
For lifetime giving, the allowance works on a rolling basis. It refreshes every seven years, in the same way the nil-rate band does. Someone planning to pass the farm down in stages can therefore use it more than once, provided the gifts are spaced far enough apart and they live long enough.
Indexation
The £2.5 million limit remains fixed until 5 April 2031. CPI index-linking applies from 6 April 2031.
Paying IHT by instalments
One important concession accompanies the reform. The option to pay Inheritance Tax by ten equal annual interest-free instalments now extends to all property eligible for APR or BPR. This applies whether the asset qualifies for 100% relief within the £2.5 million cap, or for 50% relief on the excess above it.
For farming families, this avoids a forced sale of the farm to meet an immediate IHT bill. The liability can instead be spread over a decade, interest free.
Transitional rules
The new rules are not retrospective, but they do catch some earlier transfers.
Anything transferred before 30 October 2024 (Budget day) falls entirely outside the reform. Gifts made from 30 October 2024 up to 5 April 2026 sit in a middle category. They are measured against the old rules at the point of transfer, but the capped rules apply instead where the donor dies on or after 6 April 2026 and that death falls within seven years of the gift.
Anyone who gifted agricultural property during that window should take specialist advice. The outcome depends not only on the rules in force when the gift was made, but on when the donor dies. That is a materially different position from the one most donors will have assumed at the time.
Agricultural property held in trust
Many farms are held in trust rather than owned outright, and the reform applies to trusts too, under its own rules.
A relevant property trust (one that is subject to periodic IHT charges every ten years and to exit charges when assets leave the trust) holding qualifying agricultural or business property has its own £2.5 million allowance. An individual allowance refreshes every seven years for lifetime gifting purposes; a trust allowance refreshes at each ten-year anniversary charge.
When the trust was created matters:
- Settled before 30 October 2024 and holding qualifying property before that date: capital appointments of that property out of the trust continue to follow the old rules until the next ten-year anniversary charge after 6 April 2026.
- Settled on or after 30 October 2024, or settled earlier but not holding qualifying agricultural or business property by that date: the first ten-year charge falling after 6 April 2026 is calculated under the new rules.
Where a settlor has created more than one trust, the interaction between allowances is complex. Specialist advice is essential. Claims for APR on trust property are made on form D37 alongside the relevant IHT100 return, rather than on the IHT400 schedules used for a deceased estate. HMRC sets out the detail in its guidance on claiming Agricultural Relief on assets held in a trust.
Valuing agricultural property for APR purposes
An accurate professional valuation is strongly advisable when claiming APR during probate. The valuation should identify both the property’s open market value and its agricultural value, because APR applies only to the latter. These two figures can differ considerably where land carries development potential or amenity value.
HMRC may challenge an agricultural value it considers too high, which can increase the IHT payable. Getting this right at the outset avoids delays and disputes during the probate process. For larger or more complex farms, consider whether the combined APR and BPR position needs modelling together, given the shared £2.5 million cap.

Claiming APR during probate: the process
Claiming APR forms part of completing the Inheritance Tax return submitted to HMRC. For a deceased estate the claim is made on schedule IHT414, which accompanies the main IHT400 account. The claim should be supported by:
- A professional valuation of the agricultural property showing both its open market value and agricultural value.
- Details of how the property meets the ownership and occupation conditions.
- Relevant evidence of the farming activity carried out.
Keep detailed records. HMRC may raise enquiries, and clear documentation makes it far easier to respond and to defend the claim.
APR, succession planning, and the new landscape
The reform changes the arithmetic of farm succession significantly. Larger estates above the £2.5 million threshold now carry an IHT liability where previously there was none. However, many smaller and medium-sized farms remain unaffected.
On government figures published when the threshold increase was announced, the number of estates claiming APR (including those also claiming BPR) expected to pay more IHT in 2026-27 fell from 375 to 185. Around 85% of estates claiming APR in 2026-27 are forecast to pay no more IHT as a result of the reforms.
For estates that do face a bill, succession planning deserves a fresh look. Because any unused allowance now transfers to the surviving spouse or civil partner, the risk of losing the first spouse’s allowance has largely receded. The more common issue now is the opposite. Wills drafted during 2025, when the allowance was expected to be capped at £1 million and lost if unused, may contain trust structures built specifically to bank that allowance on the first death. Those structures may no longer be necessary and can add cost and complexity for no real benefit. Any will written or revised in that period is worth reviewing.
Practical steps to consider include:
- Obtaining updated valuations of all APR and BPR assets to understand the likely IHT exposure.
- Reviewing existing wills in light of the new allowance structure.
- Considering lifetime gifts or trust arrangements, and taking advice on the transitional rules that apply to them.
- Exploring whether life insurance could fund any remaining IHT liability.
Common pitfalls when claiming APR
Several issues arise regularly when HMRC challenges APR claims.
Failing the occupation test. If the property has not been in agricultural use for the required period immediately before death, the claim will fail. Changes in land use, even temporary ones, can interrupt the qualifying period.
Overestimating the agricultural value. Confusing agricultural value with market value leads to inflated relief estimates. Always use a professional valuation that separately identifies the agricultural value and any additional value outside the scope of APR.
Farmhouse disputes. The “character appropriate” test for farmhouses is one of the most frequently litigated areas of APR. HMRC scrutinises the scale of the farmhouse relative to the agricultural operation, the farming activity actually carried out, and whether the farmhouse genuinely functioned as the operational hub of the farm. A house used mainly as a residence, or by a retired farmer, may fail the test entirely.
Overlooking the new combined cap. Under the post-April 2026 rules, APR and BPR share a single £2.5 million allowance. Claiming each in isolation, without modelling how they interact, can produce an inaccurate picture of the overall IHT position. Always consider the combined figure.
Ignoring the transitional rules for gifts. Gifts made between 30 October 2024 and 5 April 2026 can be reassessed under the new rules if the donor dies within seven years. This applies even where the gift appeared straightforward at the time.

Frequently asked questions
What is the Agricultural Property Relief cap from April 2026?
From 6 April 2026, the 100% rate of relief for APR and BPR combined is capped at £2.5 million per individual. Any qualifying agricultural or business assets above that threshold attract 50% relief, producing an effective IHT rate of 20% on the excess. The cap applies to the combined value of both reliefs, not to APR alone.
Can married couples double the APR allowance?
Yes. Any unused portion of the £2.5 million allowance transfers to a surviving spouse or civil partner. This means a couple can protect up to £5 million of combined qualifying agricultural and business assets from IHT at the 100% rate, in addition to other allowances such as the nil-rate band. The transferable allowance applies even where the first death occurred before 6 April 2026.
Should I obtain a RICS valuation to claim Agricultural Property Relief?
HMRC strongly advises using a professional valuer for land and buildings. A RICS Red Book valuation can support an APR claim. The valuation should state the property’s open market value and agricultural value separately, including any additional value attributable to factors such as development potential. HMRC may challenge an agricultural value it considers too high, so an accurate and well-evidenced valuation reduces the risk of a dispute. You can request RICS valuation quotes through The Probate Network.
Does land in an environmental scheme still qualify for APR?
It can, subject to conditions. From 6 April 2025, APR was extended to land managed under an environmental agreement with the UK government, devolved governments, public bodies, local authorities, or approved responsible bodies. The land must have been agricultural for at least two years immediately before the change of use. Not all environmentally managed land qualifies automatically, so check whether the specific scheme meets the criteria before assuming APR applies.
