Abolishing inheritance tax is no longer a fringe idea

Restore Britain has done something the major parties have repeatedly avoided: it has committed to abolishing inheritance tax in full.

That clarity matters. For years, the political debate has revolved around thresholds, reliefs, and technical adjustments. Labour has moved to expand the tax’s reach, most visibly through changes affecting farmers and family businesses. The Conservatives, when in power, preferred to tinker at the margins. Even Reform UK, for all its insurgent rhetoric, has stopped short of making abolition a defining economic position.

Restore Britain’s intervention cuts through that incrementalism. By treating inheritance tax not as a system to be adjusted but as one to be removed entirely, it forces a more fundamental question. What exactly justifies its continued existence?

Because once that question is asked directly, as Restore Britain has now done, the intellectual foundations of inheritance tax begin to look surprisingly thin.

To disrupt that transfer is to challenge something deeper than a line item in the tax code. It is to weaken the continuity between generations that underpins family life, small enterprise, and long-term stewardship. A society that treats each generation as economically self-contained risks eroding precisely the behaviours it claims to reward: responsibility, prudence, and foresight.

Restore Britain has placed this moral argument front and centre, and rightly so. The case against inheritance tax does not begin with spreadsheets but with first principles. Families are not temporary arrangements. They are enduring institutions, built over time and sustained through the transmission of both capital and obligation.

Restore Britain’s case does not rest on moral argument alone. Even on strictly economic grounds, inheritance tax proves difficult to justify.

Inheritance tax does not exist in isolation. It sits at the end of a long chain of taxation. Income is taxed when it is earned. Savings are taxed through capital gains. Consumption is taxed through VAT. By the time wealth is transferred, it has often been taxed multiple times already. In that context, inheritance tax is not a foundational pillar of the system but an additional layer, applied inconsistently and often arbitrarily.

The result is a levy that is both distortionary and inefficient. It encourages avoidance, complicates estate planning, and introduces uncertainty into long-term decision-making. For a tax that raises roughly £9 billion, around 0.7% of total receipts, the administrative and behavioural costs are disproportionately high.

International comparisons only sharpen the point. A significant number of advanced economies impose little or no tax on transfers to direct descendants. Britain, by contrast, remains among the more aggressive jurisdictions. In a world where capital is increasingly mobile, that is not a neutral choice.

The consequences are not abstract. They are felt most acutely in precisely the kinds of enterprises policymakers claim to support. Family businesses and farms, often asset-rich but cash-poor, can face substantial liabilities at the point of succession. The effect is not merely financial but structural. Assets are sold, operations are consolidated, and long-term custodianship gives way to short-term liquidity needs.

This is not a marginal issue confined to a narrow group. It speaks to a broader question about the kind of economy Britain intends to be. One built on continuity, stewardship, and intergenerational investment, or one in which capital is repeatedly reset, fragmented, and redirected through the state.

Defenders of inheritance tax tend to fall back on a familiar justification: fairness. Without such a levy, the argument goes, wealth would accumulate unchecked across generations, entrenching inequality and undermining meritocracy.

There is some force to this concern. But it is far from clear that inheritance tax achieves its stated aim. In practice, those with the greatest resources are often best placed to mitigate exposure through planning, trusts, and relocation. The burden instead falls unevenly, frequently landing on those with illiquid assets and limited flexibility.

A tax that is easily navigated by the very wealthy but destabilising for family businesses is difficult to defend on egalitarian grounds.

Restore Britain’s proposal brings that tension into the open. It does not attempt to refine inheritance tax or make it more palatable. It rejects the premise outright.

That shift is significant. A tax that raises less than one per cent of revenue, yet distorts behaviour, complicates planning, and provokes consistent public hostility, sits on increasingly unstable ground. Its persistence owes less to economic necessity than to a lingering belief that inherited wealth requires correction at the point of transfer.

But that belief is no longer as secure as it once was. The political environment has changed. The economic case has weakened. And the moral argument, centred on the ability of families to pass on what they have built, is gaining renewed force.

The question is no longer whether inheritance tax can be defended in theory. It is how long it can be defended in practice.
