Landed estates and rural businesses face unworkable inheritance tax reforms, Lords warn
From large landed estates such as the Grosvenor Estate, Chatsworth and Woburn Abbey to diversified rural businesses spanning agriculture, property, tourism and renewables, the inheritance tax changes now facing landed estates and rural enterprises go well beyond traditional farming.

“Fog of despair.”
Public debate has been sharpened in recent months by high-profile commentary, including from Jeremy Clarkson, who has warned that changes to farm taxation are creating a “fog of despair” across the farming industry. A House of Lords report published today shifts that debate away from headline rhetoric and onto a more technical but no less serious question: whether the inheritance tax reforms affecting landed estates and rural businesses are workable at all.
Inheritance tax reforms affecting landed estates and rural businesses are not practically workable in their current form, according to the report, which warns that liquidity pressure, valuation disputes and unrealistic payment deadlines risk forcing asset sales and undermining long-term stewardship.
While the report is supportive in tone, its conclusions are sceptical. Peers say the Government has underestimated the administrative, liquidity and human impact of the changes on families dealing with death, and that serious risks remain for estates and rural enterprises where value is concentrated in illiquid land, property and trading assets. Although the proposals have been revised since October 2024, the Lords conclude that they have not been adequately stress-tested.
A report that questions workability, not intent
The report is also critical of the way the reforms were developed. Consultation, it says, came too late and involved too narrow a group of stakeholders. Repeated redesign has created uncertainty at the point of succession, and the difficulties arising from changes to agricultural property relief and business property relief are explicitly linked to failures in tax policymaking rather than drafting alone. The Committee further criticises the absence of analysis on how many estates and rural businesses may be forced into asset sales as a direct result of the changes.
Liquidity, timing and the six-month deadline
Liquidity and timing are central concerns. The Lords describe the six-month inheritance tax payment deadline as unrealistic for estates holding qualifying APR and BPR assets and urge the Government to extend the deadline to 12 months. They warn that higher and more contested valuations, combined with probate sequencing issues and a fixed payment timetable, create a material risk of liquidity stress even where instalment payment options exist.
Valuations become the new fault line
A further concern is that the reforms make valuation outcomes more consequential, with thresholds and cliff edges likely to increase both contention and delay. The Lords highlight the growing risk of disputes with HMRC, delays arising from shortages of specialist rural and business valuers, and exposure to late payment interest even where personal representatives are acting in good faith.
Older owners and anti-forestalling constraints
Older owners are identified as being disproportionately exposed. Anti-forestalling rules restrict the ability of older landowners to undertake lifetime planning, a position the Lords describe as unfair where death occurs before any meaningful restructuring can be carried out.
Warnings first raised at the October Budget
When Citywealth reported on the October Budget last year, advisers warned that estate and succession planning for landed estates and agricultural businesses was entering a more constrained and time-sensitive phase.
Consultation and legislative process under scrutiny
The House of Lords’ findings have prompted strong reactions from advisers working with landed estates and rural businesses. Jamie Austen, Partner specialising in Trusts, tax and estate planning at Collyer Bristow said: “The Committee has laid bare what many of us have long suspected: that these reforms were made first and understood only afterwards. When an eminent Parliamentary Committee concludes that basic consultation came ‘too late and too narrowly’, one must ask: how did the Government allow itself to get here at all?”
He said the report confirmed that the APR and BPR changes were “not merely imperfect — they are unready”, adding that poor consultation inevitably leads to poor law. “No responsible legislature should accept a six-month tax deadline that even diligent families cannot realistically meet,” he said, describing the timetable as “unworkable by design”. Austen added that repeated government revisions were symptoms of a policy conceived without foundations and said the report read as a “masterclass in how not to legislate for complex family businesses and farms”. He also pointed to the Committee’s repeated references to Collyer Bristow’s evidence, saying these underlined the concerns being pursued through judicial review on behalf of affected farmers and business owners.
Forced sales and pressure on rural enterprises
Concerns about liquidity and forced sales are echoed by advisers working with rural enterprises. Lauren Parker, Partner private client team and who specialises in advising landed estates and land consortia at Mills & Reeve, said: “Although the increase in the 100% APR/BPR allowance from £1m to £2.5m has been welcomed, for many rural family business owners it does not go far enough in protecting their businesses from the risk of significant future inheritance tax liabilities, which may need to be funded from asset sales. We know that rural businesses tend to be asset rich but cash poor, with land prices riding high and farming returns being low.”
Gemma Shepherd, Partner, Tax, Trusts and Succession team at law firm, Michelmores said: “For many family-owned landed estates and rural businesses, the enterprise is far more than a financial asset. It represents generations of stewardship, identity and long-term responsibility for land, people and place. The upcoming inheritance tax changes risk placing that legacy under significant strain, as families confront the possibility of tax charges that could force the sale or break-up of carefully preserved estates and businesses.”
She added: “Although reliefs continue to play an important role, they are becoming increasingly restricted and complex to navigate. The more recent announcements including an increased relief threshold and greater flexibility for spouses and civil partners are welcome; however, they do not remove the underlying challenge of preserving capital-intensive, income-light assets in the long term.”
Structural change and long-term stewardship
Celia Speller, Senior Associate at Farrer & Co, said: “The newly announced £2.5m cap on 100% APR/BPR from 6 April 2026 means that larger estates will face a 50% relief rate on the excess, increasing IHT exposure for many farming and business-owning families. While the transferability between spouses will help couples access up to £5m in relief, more valuable family businesses will come under huge pressure.”
She said restructuring strategies are time-sensitive, with transfers before April 2026 benefitting from unlimited relief, creating a cliff edge once the cap is introduced. “For many landed estate owners and rural family businesses, the most significant challenge is not simply reduced relief but the structural shift in how these businesses must plan for long-term stewardship,” she said. “The new regime forces business owners to address not only succession objectives or tax issues, but operational ones, including how illiquid their assets are, how a tax liability would be funded, and whether the business remains viable in the long term.”
Planning mechanics and narrowing timeframes
John Endacott, tax partner and head of wealth and succession at PKF Francis Clark, said: “Given the potential exposure to inheritance tax on rural businesses, clients need to develop a long-term strategy to minimise the risk of a tax charge. This should be based on good legal, valuation and tax advice. There is a need to focus more on the valuation of assets, including shares in family companies, as lower is now better.”
He added: “Spreading ownership across individuals and trusts is incentivised by the £2.5m allowance, although care is required on the reservation of benefit rules. The focus currently is on maximising gifts into trust ahead of 5 April 2026, but a new focus is developing on agricultural and business property held by pension schemes, especially self-invested personal pensions and small self-administered schemes.”
Charles Frost, Managing Associate at law firm Michelmores, said: “Many rural businesses have already undertaken restructuring based on the earlier draft legislation, which provided for a £1 million allowance that was not transferable between spouses. Following the recent revisions to the draft legislation, increasing the allowance to £2.5 million and allowing it to be transferred between spouses, it may be sensible to revisit that planning. These amendments may create opportunities to refine recent planning to reflect this amended position.”
“Looking beyond 6 April, trusts will remain a key feature of many business-owning structures, including
landed estates. For trusts established under the ‘old’ rules (pre-October 2024), there may be opportunities
in the period leading up to the next ten-year anniversary to consider extracting assets on a more favourable
basis. Trustees should therefore carefully consider whether this window can be used to their advantage.”
Simon Mitchell, Partner and who heads up the Wills, Estate & Tax Planning team at Thomson Snell & Passmore, said: “Estate and succession planning remains in sharp focus for clients who own farms and other businesses as a result of the continuing development of the inheritance tax reliefs applying to agricultural and business assets. While the Government has relaxed its original proposals by increasing the cap on agricultural and business relief to £2.5m per person and allowing it to be transferred between spouses, wider questions remain about how workable the new rules will prove to be in practice once they take effect from April 2026.
“For clients holding agricultural and business assets, it remains sensible to take advice to ensure that an appropriate estate and succession plan is in place. This is likely to involve looking beyond those assets alone and considering a wider range of options, including lifetime gifting and investment planning, alongside the continued importance of lasting powers of attorney.
“Looking ahead, further complexity is expected from the proposed reforms to the taxation of pensions from April 2027, which will bring pension assets into the inheritance tax calculation on death. This may change long-established planning assumptions and could also add to delays in estate administration, reinforcing the need for careful, forward-looking advice.”
Tim Adams, Partner at accountancy firm Saffery, said: “For estate owners and family farming businesses, 2026 is less about a single policy change and more about day-to-day resilience, including rigorous budgeting, cashflow headroom and faster decision cycles.” He said farming margins were already under pressure from harvest variability, input price shifts and higher wage and NIC costs, making portfolio stress-testing and early working-capital buffers increasingly important.
While the increase in the APR and BPR cap is welcome, Adams said long-term planning remains essential for values above the threshold where only 50% relief is available, particularly for those holding AIM-type investments now restricted to 50% relief. He warned that decisions driven solely by inheritance tax mitigation can reduce asset protection and flexibility, noting that donors cannot retain income from gifted assets if gifts are to be effective.
Final planning pressures ahead of April 2026
Helen Clarke, Partner at law firm Irwin Mitchell Private Client Advisory, said that with only weeks left until the cap takes effect on 6 April 2026, owners face increasing pressure. “Waiting for the final wording of the Finance Bill risks missing a narrow window to gift unlimited APR/BPR assets into trust without being constrained by entry charges,” she said.
She added that although recent concessions have helped, they have not removed the planning imperative or concerns around cashflow and business continuity once relief falls to 50% above the threshold. Advisers, she said, are already seeing rushed gifting and false reliance on staying under the cap, despite fluctuating asset values.
Conclusion
The House of Lords report does not call for minor technical adjustment. Instead, it raises broader questions about whether the inheritance tax reforms have been designed with the practical realities of landed estates and rural businesses in mind. For advisers, the significance of the report lies not only in its focus on liquidity, valuations and deadlines, but in its wider critique of how complex tax policy has been developed and implemented.
For those running estates and rural enterprises, the sense of uncertainty described by advisers helps to explain why public concern has intensified. When Jeremy Clarkson speaks of a “fog of despair” settling over farming, the Lords’ report provides a parliamentary explanation for that unease. With assets often illiquid and planning windows narrowing, the risks identified by the Committee are no longer theoretical, but immediate.
