Policy experts have renewed calls for a significant overhaul of the UK’s inheritance tax structure, arguing that it acts as a deterrent to investment and entrepreneurship.


Leading economic think tanks and business groups have challenged the government to simplify or abolish the existing system, warning that the UK remains an international outlier with one of the highest levels of inheritance taxation among developed countries.


These pressures highlight growing concerns around economic competitiveness and the challenges facing families and small businesses navigating the current tax framework.

Overview of Current Inheritance Tax

The UK inheritance tax is levied at a rate of 40 per cent on estates exceeding a standard threshold of £325,000, with the threshold rising to £500,000 if a primary residence is transferred directly to children.


According to the latest data from HM Revenue & Customs, inheritance tax revenues have continued to increase, driven by rising property values and asset inflation.


This taxation applies to assets passed on at death, after exemptions and reliefs are accounted for. Critics argue that, as the tax is applied to wealth accumulated over a lifetime and often already taxed via income tax and other levies, it places an additional burden on families.

OECD Comparisons

Analysis from economic research institutions highlights that nearly half of the 38 countries in the Organisation for Economic Co-operation and Development (OECD) do not impose inheritance taxes on transfers to adult children.


By comparison, the UK ranks among a minority of high-income nations retaining significant levies on family succession. These international comparisons have fuelled calls for reform, with business leaders and economists expressing concern that the UK's approach risks putting it at a disadvantage in attracting and retaining wealth creators and entrepreneurs.

Economic and Entrepreneurial Impact

There is growing evidence that the inheritance tax regime may influence decisions regarding investment and the location of entrepreneurial activity. Some experts argue that complex and high taxation can discourage business formation and drive capital abroad.


A recent report by the Institute of Economic Affairs described the current system as “arbitrary and distortionary,” noting the government spends an estimated £66 million annually on collection costs alone.


Rory Meakin, the report’s author, stated: “Inheritance tax is arbitrary, complex, and drives away the entrepreneurs Britain needs.”

Political Pressures and Recent Changes

Political debate over inheritance tax intensified following changes in the 2024 Autumn Budget, when the government replaced longstanding reliefs for family farms with a revised set of exemptions.


Widespread protests led to a policy reversal in December, with the tax-free threshold for agricultural assets raised to £2.5 million. This episode underscored the sensitivity of inheritance tax policy and its impact on both rural communities and small businesses.


Opposition parties and advocacy groups continue to press for wider reforms to make the tax system simpler and less punitive.

Feedback from Policy Institutes

Policy commentators and think tanks have called inheritance tax a “deadweight” on the economy, with some advocating outright abolition. Lord Frost, Director General of the Institute of Economic Affairs, said: “A nation serious about growth and about giving families the freedom to build something lasting would not levy a 40 per cent charge on wealth that has already been taxed.” Some advocates suggest interim measures such as raising the exemptions threshold, lowering the rate, or modernising rules around lifetime gifts, which could provide practical relief while longer-term options are explored.

Final Summary

The UK’s inheritance tax system remains under sustained scrutiny from economic, business, and political actors. With critics highlighting the UK’s status amongst the highest-taxing countries for bequests, the debate is centred on both the economic impact and perceived fairness of the current threshold and rate. Calls for reform are likely to continue, with discussions ranging from practical amendments to full abolition, in pursuit of a more balanced approach to family succession.
