The farm inheritance tax reform 2026 caps a relief that was uncapped for decades: from 6 April 2026, only the first £2,500,000 of combined agricultural and business property passes with 100% relief per person, with 50% relief above, an effective inheritance tax rate of up to 20% on the excess (gov.uk, as at August 2026, subject to change).
Check the figure first. The cap is £2,500,000, not the £1,000,000 quoted across older guides. The £1m version was the first draft, raised on 23 December 2025, so treat any page citing £1m for a death on or after 6 April 2026 as out of date. This guide covers the law of England and Wales; figures are current as at August 2026 and subject to change.
What is the farm inheritance tax reform 2026?
The farm inheritance tax reform 2026 is the capping of agricultural property relief (APR) and business property relief (BPR), which until now let qualifying farms pass free of inheritance tax without limit. From 6 April 2026, full 100% relief is limited to a combined £2,500,000 per person, with 50% relief above, so larger working farms face a bill for the first time in a generation.
It is not a single switch. The reform pairs the 2026 cap with unused pensions entering the estate in 2027 and a longer freeze on the nil-rate bands, three separate dates that together raise inheritance tax on farming estates.
When does each part of the reform take effect?
The reform runs across several dates, not one. The cap starts on 6 April 2026, an anti-forestalling rule reaches back to gifts made from 30 October 2024, pensions are drawn in from 2027, and the nil-rate band freeze now runs to 2031. Read in order, the dates show what applies to a death today and what is still coming.
| Date | What changed |
|---|---|
| 30 October 2024 | Autumn Budget 2024 announces the APR and BPR cap. Gifts of farm assets from this date can be caught by anti-forestalling rules if the giver dies on or after 6 April 2026. |
| 26 November 2025 | Budget 2025 extends the freeze on the nil-rate band, residence nil-rate band and taper threshold to 5 April 2031. |
| 23 December 2025 | The 100% relief cap is raised from £1,000,000 to £2,500,000 per person, transferable to £5,000,000 per couple. |
| 6 April 2026 | The reform takes effect: £2,500,000 at 100% relief, 50% above, with interest-free instalments over 10 years on APR and BPR assets. |
| 6 April 2027 | Unused pension funds are brought into the estate for inheritance tax. |

What changed for agricultural and business property relief?
Before 6 April 2026, qualifying agricultural and business property often attracted unlimited 100% relief, so most farms passed with nothing to pay. From that date, 100% relief is capped at a combined £2,500,000 per person, and value above the cap gets 50% relief. The allowance is transferable between spouses and civil partners, so a farming couple can shelter up to £5,000,000 in full.
| Feature | Before 6 April 2026 | From 6 April 2026 |
|---|---|---|
| 100% relief cap | No cap on qualifying assets | First £2,500,000 combined per person |
| Relief above the cap | Not applicable | 50% relief, effective rate up to 20% |
| Transferable to a spouse | Not applicable | Yes, up to £5,000,000 per couple |
| Allowance refresh | Not applicable | Every 7 years for individuals |
| Paying the tax | Instalments available on land | Interest-free over 10 years for APR and BPR assets |

How much inheritance tax will farms actually pay now?
Most farms will still pay nothing, because the £2,500,000 cap (or £5,000,000 for a couple) covers many holdings in full, with the nil-rate bands on top (£325,000 each, plus up to £175,000 where a home passes to direct descendants, both frozen to 5 April 2031). Where a farm exceeds the cap, only the excess is affected, at 50% relief, an effective rate of up to 20%. This worked example shows the mechanics on a £4,000,000 farm; figures are illustrative and rounded.
- Confirm the relief available. A single farmer has £2,500,000 of APR and BPR relief at 100%; a surviving spouse who inherited the first allowance has £5,000,000.
- Compare the farm value to the allowance. On a £4,000,000 farm held by one person, £2,500,000 is covered in full and £1,500,000 sits above the cap.
- Apply 50% relief to the excess. Half of the £1,500,000, so £750,000, remains taxable.
- Apply the 40% rate. Tax on £750,000 at 40% is £300,000, an effective rate of about 20% across the £1,500,000 over the cap.
- Spread the payment. That £300,000 can be paid over 10 annual instalments, interest-free on qualifying APR and BPR assets, easing pressure to sell land.
The same £4,000,000 farm can pass with nothing to pay where a couple preserve both £2,500,000 allowances, because £5,000,000 of combined relief covers it in full. Preserving both allowances is central to estate planning for farming families, and our inheritance tax planning strategies guide sets out how they interact.
What do people still get wrong about the reform?
Three misreadings come up again and again, and each can cost a family real money: that it is a flat tax on every farm, that the cap is fixed at £1m, and that a quick gift will sidestep it.
The £1m figure is the biggest. Guides written before 23 December 2025 still quote a £1,000,000 cap, raised to £2,500,000 per person and transferable to £5,000,000 per couple. A family reading the old number may over-estimate the bill and act on a figure that no longer applies.
Next is timing on gifts. Giving the farm away is not an instant fix. A gift is a potentially exempt transfer that only leaves the estate if the giver survives seven years, and gifts made on or after 30 October 2024 can be pulled back into the reformed rules if death falls on or after 6 April 2026. Living in the farmhouse or drawing farm income after a gift can also breach the reservation of benefit rules, so it may not work at all. Because attorneys can make only limited gifts, a plan is best set down while the owner has capacity, one reason a lasting power of attorney matters for farming families.
Third is pensions. Many farmers hold pensions built up off-farm that have passed free of inheritance tax, and from 6 April 2027 unused pension funds count as part of the estate. A pension once earmarked as a legacy can push a farm over the thresholds, so it may be better drawn on in retirement (gov.uk, as at August 2026, subject to change).

Frequently asked questions
What is the new inheritance tax rule for farmers in 2026?
From 6 April 2026, agricultural and business property relief is capped at a combined £2,500,000 per person at 100%, with 50% relief above, an effective inheritance tax rate of up to 20% on the excess. The allowance is transferable, so a couple can shelter up to £5,000,000 in full. Uncapped relief no longer applies (gov.uk, as at August 2026, subject to change).
Is the farm inheritance tax cap £1 million or £2.5 million?
It is £2,500,000 per person. The £1,000,000 figure was an earlier draft, raised to £2,500,000 on 23 December 2025 and transferable to £5,000,000 per couple. Any guide citing £1m for a death on or after 6 April 2026 is out of date, so check the figure before you rely on it (House of Commons Library, as at August 2026).
When does the farm inheritance tax reform start?
The main APR and BPR cap applies to deaths on or after 6 April 2026. An anti-forestalling rule reaches back to gifts made from 30 October 2024, the nil-rate band freeze runs to 5 April 2031, and unused pensions enter the estate from 6 April 2027. The reform runs across several dates rather than one (gov.uk, as at August 2026, subject to change).
How much inheritance tax will farms pay under the reform?
Value within the £2,500,000 cap passes at 100% relief with nothing to pay. Value above the cap gets 50% relief, so half is taxable at 40%, an effective rate of up to 20% on the excess. On a £4,000,000 farm held by one person, roughly £300,000 could be due, payable over 10 interest-free instalments. A couple preserving both allowances may pay nothing on the same farm.
Can farmers still avoid inheritance tax by gifting the farm?
Not reliably. A gift of the farm is a potentially exempt transfer that leaves the estate only if the giver survives seven years, and gifts made on or after 30 October 2024 can be pulled back into the reformed rules if death falls on or after 6 April 2026. Living in the farmhouse or drawing farm income after a gift can breach the reservation of benefit rules, so take advice before acting.
