Two deadlines are reshaping UK estate planning. From April 2026, Business Property Relief (BPR) and Agricultural Property Relief (APR) face a £1 million cap — stripping protections that generations of farm and business owners relied on completely. From April 2027, unspent pension pots will become subject to Inheritance Tax (IHT) for the first time, overturning a cornerstone of retirement wealth strategy. Chancellor Rachel Reeves delivered both changes in her October 2024 Autumn Budget, alongside a continuation of the Nil-Rate Band freeze first introduced in 2009. The combined effect: more estates will pay IHT than at any point in the past two decades. This guide explains the three major reforms, who they affect, and the practical steps to protect your estate before the deadlines arrive.
Three Budget Changes That Redraw the IHT Landscape
The Autumn Budget 2024 introduced three substantive reforms to Inheritance Tax, two of which take effect within the next two years. Understanding each one separately is essential before assessing the combined impact on your estate.
Reform 1: The APR and BPR Cap (from 6 April 2026)
Agricultural Property Relief and Business Property Relief previously offered 100% relief on qualifying assets of any value. From April 2026, the combined 100% relief is capped at £1 million per estate. Assets above that threshold will attract 50% relief — meaning an effective IHT rate of 20% (50% of the standard 40% rate) on the excess. For a farming family with land worth £3 million, the change transforms a zero IHT liability into a potential bill of £400,000.
Reform 2: AIM-Listed Shares Lose Full Relief (from 6 April 2026)
Shares in companies listed on the Alternative Investment Market (AIM) and similar exchanges previously qualified for 100% BPR after two years of ownership. From April 2026, that relief falls to 50%, making AIM portfolios held specifically for IHT planning significantly less effective.
Reform 3: Pension Pots Become Part of the Taxable Estate (from 6 April 2027)
Defined contribution pension funds are currently held outside the estate for IHT purposes — a structural feature that made pensions one of the most powerful wealth transfer tools in the UK. From April 2027, unspent pension pots will be included in the deceased's taxable estate. The pension provider will be responsible for paying any IHT due before funds are released to beneficiaries [HM Treasury, Autumn Budget 2024]. The full technical details are published by HMRC in their Inheritance Tax guidance on GOV.UK.
Understanding the full scope of these changes — and the probate implications they bring for UK families — is the starting point for any updated estate plan.
Who the APR and BPR Cap Hits Hardest
The £1 million combined cap on 100% relief targets a narrow but economically significant group: family farms, rural estates, private business owners, and investors who used AIM portfolios as a deliberate IHT mitigation strategy. Individuals who believed their succession planning was complete will need to revisit valuations urgently before April 2026.
How the Relief Reduction Works in Practice
The following table shows how the new rules change IHT exposure on qualifying business and agricultural assets:
| Asset Value | Relief Before April 2026 | Relief After April 2026 | Effective IHT Rate After 2026 |
|---|---|---|---|
| Up to £1 million | 100% | 100% | 0% |
| £1m – £2m | 100% | 50% on excess | 20% on excess |
| £2m – £5m | 100% | 50% on excess | 20% on excess |
| Over £5m | 100% | 50% on excess | 20% on excess |
| AIM shares (2yr+ hold) | 100% BPR | 50% BPR | 20% effective rate |

What Farm and Business Owners Should Do Before the Deadline
The government confirmed the £1 million threshold is per individual, not per couple — meaning married couples may be able to combine allowances, but the position requires specialist legal advice to confirm. Given the complexity, a structured response to the change typically involves:
- Commission an up-to-date valuation of all qualifying assets before April 2026
- Identify assets that fall above the £1 million threshold
- Consider restructuring ownership (e.g. transferring shares to a spouse before the deadline)
- Explore the use of discretionary trusts for assets exceeding the cap
- Review shareholder agreements and partnership deeds to ensure they remain efficient after reform
Rachel Reeves' wider approach to wealth taxation — including the measures outlined in the Spring Statement 2026 for UK financial planning — signals that further reform of reliefs used primarily by high-net-worth estates remains a political priority.
Frozen Thresholds: The Stealth IHT Rise Affecting Ordinary UK Families

The IHT Nil-Rate Band (NRB) has been fixed at £325,000 since April 2009 — nearly 17 years without adjustment. The Residence Nil-Rate Band (RNRB), introduced in 2017 to offset the impact of rising property values, sits at £175,000. Both are frozen until at least April 2030 under the government's current plans.
What the Freeze Means in Numbers
A couple with a home can shelter up to £1 million from IHT by combining their allowances (NRB × 2 = £650,000 plus RNRB × 2 = £350,000 — provided the home passes to direct descendants). Anything above that threshold is taxed at the standard 40% rate. That threshold sounds substantial, but UK house price inflation has eroded its real value sharply.
The average UK house price in 2009 was approximately £162,000 [UK House Price Index, ONS 2024]. By early 2026, the national average had risen above £290,000 — and in London and the South East, average prices exceed £500,000. Estates that comfortably sat below the IHT threshold when first planned a decade ago may now be well above it, with no action taken and no advice sought.
HMRC Inheritance Tax receipts reached £7.5 billion in 2023/24, a record high [HMRC, October 2024]. The OBR forecasts receipts will continue rising as the threshold freeze extends and property values rise.
When the RNRB Does Not Apply
The Residence Nil-Rate Band is not automatic. It applies only when a qualifying residential property is left to direct descendants (children, grandchildren, stepchildren, adopted children). Estates over £2 million face a tapering reduction of £1 for every £2 above that level, removing the benefit entirely for very large estates. Anyone with a complex family structure, a property in trust, or a will that does not explicitly direct the home to direct descendants should review whether they are claiming the full allowance.
Pension Pots and IHT: Why 2027 Changes Your Retirement Strategy
For more than two decades, the UK's defined contribution pension system offered a powerful estate planning advantage: pension pots sit outside the taxable estate. A retiree could draw on their ISA or property wealth first, leaving a pension to pass inheritance-tax-free to children or grandchildren. The April 2027 change eliminates that structure.
How the New Pension IHT Rules Will Work
From 6 April 2027, the value of any unspent defined contribution pension fund at death will be included in the deceased's taxable estate for IHT purposes. The pension provider — not the estate — will be required to calculate and pay the IHT attributable to the pension before releasing funds to beneficiaries. The practical consequence is that beneficiaries could receive considerably less than they expected, particularly where the pension pot is large relative to the estate's other assets.
The "Pension First" Strategy and Its Limits
The most widely discussed response to the 2027 change is to reverse the conventional drawdown order: spend pension funds earlier in retirement rather than preserving them as a legacy vehicle. However, this approach is not appropriate for everyone. Drawing additional pension income can push retirees into higher Income Tax brackets, and spending pension assets earlier reduces the fund available to generate retirement income if you live longer than expected.
À retenir : The right strategy depends entirely on individual circumstances — your pension size, other assets, intended beneficiaries, and Income Tax position. There is no universal "right answer" to the 2027 change, which makes personalised financial advice more important than ever.

Practical Estate Planning Steps to Reduce Your IHT Bill in 2026

A real-world scenario: James, 67, owns a semi-detached house in Bristol worth £420,000, a pension worth £280,000, and savings of £110,000. His total estate stands at roughly £810,000. When he originally made his will in 2015, his estate was below the IHT threshold for a single person. Today, with his wife already deceased and no RNRB if the house isn't left to his son, he faces a potential IHT bill of approximately £194,000 on assets above the NRB. A review of his will, gifting strategy, and pension drawdown order could reduce that figure significantly.
The following steps are the core toolkit for reducing IHT exposure under the current rules:
- Use your annual gift exemption. Each individual can give away up to £3,000 per tax year free of IHT. Unused allowance can be carried forward one year. A couple can give £12,000 in two years without any IHT risk.
- Make gifts from surplus income. Regular gifts made out of normal income (not capital) are immediately exempt from IHT, regardless of size — provided they form part of a habitual pattern and do not reduce your standard of living [HMRC, Inheritance Tax Manual].
- Understand Potentially Exempt Transfers (PETs). Gifts above the annual exemption are exempt from IHT if the donor survives seven years after making them. Gifts within seven years may attract IHT on a sliding scale under taper relief rules.
- Write life insurance in trust. A whole-of-life policy written in trust pays out outside the estate, providing a lump sum to cover the IHT bill without increasing the estate's value.
- Consider a discretionary trust. A discretionary trust can remove assets from the estate while retaining flexibility over beneficiaries — particularly useful for families with changing circumstances or where direct inheritance is not desirable.
- Review your will for RNRB eligibility. Ensure your home is explicitly directed to direct descendants in your will. A will that leaves property to a trust may unintentionally forfeit the £175,000 Residence Nil-Rate Band.
- Re-evaluate pension drawdown order. Given the April 2027 change, consider drawing from pension funds earlier to avoid a large unspent pot being subject to IHT, balanced against Income Tax exposure.
Frequently Asked Questions About Inheritance Tax 2026
Is Inheritance Tax being abolished in 2026?
No. Despite periodic political discussion about abolishing IHT, the Autumn Budget 2024 confirmed continuity of the tax. The budget introduced tighter reliefs and extended the frozen thresholds — the opposite of abolition. IHT is expected to raise over £9 billion annually by the end of the decade [OBR, October 2024].
What is the Inheritance Tax threshold in 2026?
The standard Nil-Rate Band remains £325,000 per individual. An additional Residence Nil-Rate Band of £175,000 applies if a main home is left to direct descendants. A married couple can therefore shelter up to £1 million combined, provided both allowances are applied correctly and the estate does not exceed £2 million (at which point RNRB tapers out).
How will the pension IHT change affect me?
If you have a defined contribution pension and plan to leave an unspent pot to your beneficiaries, the value of that pot will be included in your IHT estate from April 2027. The pension provider will be responsible for paying IHT before distributing funds. You should model the combined effect of your pension, property, and other assets against the available thresholds now, not in 2027.
What is the seven-year rule for gifts?
A Potentially Exempt Transfer (PET) is a gift above the annual exemption that becomes fully exempt from IHT if the donor lives for seven years after making it. If the donor dies within seven years, the gift may attract IHT on a sliding scale: no reduction in years 1–3, then 20%, 40%, 60%, 80% reductions in years 3–7 respectively (taper relief).
Do married couples or civil partners have a higher threshold?
Yes. When a spouse or civil partner dies, their unused NRB and RNRB can be transferred to the surviving partner. This means a surviving spouse can hold a combined allowance of up to £650,000 (NRB) plus £350,000 (RNRB), giving a total of £1 million before IHT applies — provided the estate meets the qualifying conditions for RNRB.
