Death by a Thousand Thresholds: Labour's Inheritance Tax Squeeze Is Targeting the Middle Class
Rachel Reeves stood at the despatch box in October 2024 and delivered a Budget that her party insisted was targeted at wealth. The headline numbers were carefully calibrated to avoid triggering the political alarm bells that accompany any overt raid on ordinary savers. There was no dramatic reduction in the nil-rate band. There was no announcement of a new death tax. What there was, buried in the technical schedules and Office for Budget Responsibility forecasts, was something considerably more damaging: a sustained, multi-year squeeze on the thresholds, reliefs, and exemptions that have historically protected family farms, small businesses, and the accumulated savings of middle-income households from the full force of a 40 per cent death duty.
The mechanism is bracket creep — the oldest trick in the fiscal illusionist's repertoire. Keep the headline rate unchanged. Freeze the thresholds. Allow inflation and rising asset prices to do the work of expanding the tax base without the political cost of announcing a rise. By 2030, on current Treasury projections, inheritance tax receipts are forecast to exceed £9 billion annually, up from approximately £7 billion in 2023-24. That money is not coming from a new class of the newly wealthy. It is coming from families who bought houses in the 1980s, built small businesses over thirty years, or farmed land that has been in their family for generations.
What the Budget Actually Did
The most significant change in the October 2024 Budget was the decision to bring inherited pension pots within the scope of inheritance tax from April 2027. Previously, defined contribution pension funds passed outside of an estate on death, representing a legitimate and widely used mechanism for intergenerational wealth transfer. The Chancellor's decision to end that exemption was framed as closing a loophole exploited by the wealthy. In practice, it affects any individual who has been diligently contributing to a workplace pension throughout their working life and hoped to leave unused funds to their children.
Equally significant were the changes to Agricultural Property Relief and Business Property Relief. Under the new rules announced in the Budget, assets qualifying for these reliefs will attract only 50 per cent relief above a £1 million threshold, rather than the 100 per cent relief that previously applied. For a family farm worth £3 million — a figure that sounds large until one considers that agricultural land in England averages over £10,000 per acre — this creates a potential inheritance tax liability of several hundred thousand pounds on an asset that generates modest annual income and cannot easily be liquidated without destroying the business it supports.
The National Farmers' Union estimated that approximately 70,000 farms in England could be affected by the change. The government disputed this figure, but its own impact assessment acknowledged that several thousand farms would face material tax liabilities they had not previously anticipated. The protests that followed — farmers driving tractors through Westminster in November 2024 — were not the confected outrage of wealthy landowners. They were the legitimate alarm of working families who had structured their affairs on the basis of rules that had existed for decades, and who were now being told, with minimal notice, that those rules no longer applied.
The Aspiration Tax
There is a philosophical point here that transcends the specific policy details, and it is one that conservatives should make without apology. Inheritance tax, at its core, is a tax on the desire to provide for one's children. It is levied on wealth that has already been taxed — through income tax, national insurance, capital gains tax, and stamp duty — at every stage of its accumulation. The state takes its share when you earn money, takes another share when you invest it, takes a further share when you sell assets, and then, when you die, takes 40 per cent of whatever remains above a threshold that has not kept pace with inflation or house price growth for fifteen years.
The standard progressive counter-argument is that inheritance perpetuates inequality — that unearned intergenerational transfers entrench advantage and undermine social mobility. It is a coherent position, and it deserves engagement rather than dismissal. But the empirical evidence for inheritance tax as an effective redistributive mechanism is weak. Research from the Institute for Fiscal Studies and comparable international studies consistently finds that death duties are among the most economically inefficient taxes available to a government, generating significant behavioural distortions — including asset hoarding, early gifting, and complex trust structures — while raising relatively modest revenue compared to their economic cost.
Moreover, the inequality argument proves too much. If the objection is to unearned advantage, the logical target is the truly dynastic wealth of the ultra-rich — the kind of multi-generational trusts and offshore structures that sophisticated tax planning has always placed beyond the reach of simple inheritance tax rules. Those structures remain largely untouched. What has been tightened is the relief available to the farmer who cannot afford a Mayfair tax solicitor, and the pension saver who assumed the rules he had planned around would still apply when he died.
The Small Business Dimension
The changes to Business Property Relief deserve particular attention. Britain's 5.5 million small and medium-sized enterprises are the backbone of the private sector economy, accounting for approximately 60 per cent of private sector employment. Many of them are family-owned businesses — passed from founder to child to grandchild — that have been built over decades through personal sacrifice, reinvested profits, and deferred consumption.
The full 100 per cent Business Property Relief that previously applied to qualifying business assets was not a loophole. It was a deliberate policy choice, made and maintained by governments of both parties, on the grounds that forcing heirs to sell or wind up viable businesses in order to pay inheritance tax is economically destructive and socially unjust. The October 2024 changes have partially unwound that logic. The £1 million threshold sounds generous until one considers that a modest manufacturing business with premises, equipment, and stock can easily exceed that figure in asset value while generating a fraction of the income needed to service a six-figure tax bill.
What Comes Next
The government has committed to reviewing the implementation of the agricultural and business property changes before they take effect. That review should be watched closely. There is a meaningful difference between a government that has made a policy error and is willing to correct it, and a government that is using a consultation process to absorb political pressure while proceeding regardless.
The broader trajectory is clear. With public spending commitments that the OBR has assessed as optimistic and a tax base already stretched by years of fiscal pressure, the temptation to continue squeezing inheritance tax thresholds and reliefs will not diminish. Frozen thresholds are the path of least political resistance. Families who have worked hard, saved diligently, and hoped to pass something on to their children deserve to understand what is being done to those hopes — and to hold the government accountable for it.
Labour promised not to raise taxes on working people. What it has delivered is a sustained assault on the wealth that working people spend their lives building — one frozen threshold at a time.
