The UK government is facing increasing pressure to reconsider its inheritance tax (IHT) system, with critics arguing that the policy places Britain among the world’s highest-taxing countries on family wealth transfers.
Economists and policy groups are urging the Labour government to abolish or reform the current inheritance tax structure, warning that it could discourage investment and push entrepreneurs to move their assets abroad.
A new report from the Institute of Economic Affairs (IEA) has reignited debate around inheritance tax, describing the current system as complex, economically damaging, and unfair to families who want to pass on wealth to the next generation.
How Inheritance Tax Works in the UK
Inheritance tax is charged on the value of an estate when a person dies. Currently, the UK government applies a 40 percent tax rate on estates worth more than £325,000.
However, there are some allowances and exemptions. If the deceased person leaves their main residence to their children or direct descendants, the threshold can increase to £500,000. Any value above the threshold may be subject to the 40 percent inheritance tax rate.
While this tax applies only to estates above a certain value, critics argue that it can still affect middle-class families who have accumulated assets such as property over many years.
UK Compared With Other Developed Economies
The IEA report highlights that the UK stands out compared to many other developed countries when it comes to taxing inherited wealth.
Among the 38 member countries of the Organisation for Economic Co-operation and Development (OECD), nearly half do not impose taxes on bequests passed to adult children. These countries instead rely on other forms of taxation and avoid taxing family inheritance directly.
According to the report, this places Britain among a relatively small group of nations that heavily tax inherited wealth, making it a “high-tax outlier” compared to other advanced economies.
Critics argue that such policies could weaken the UK’s economic competitiveness and discourage long-term wealth creation.
Critics Say Tax Harms Economic Growth
The report from the Institute of Economic Affairs describes inheritance tax as a “distortionary” burden on the economy.
Economists argue that wealth passed through inheritance has often already been taxed multiple times during a person’s lifetime through income tax, national insurance contributions, and value-added tax (VAT).
Because of this, some experts believe inheritance tax effectively taxes the same wealth repeatedly, which they say discourages saving, investment, and entrepreneurship.
Lord Frost, Director General of the IEA, said countries aiming to encourage economic growth and support family businesses should reconsider such policies.
According to him, a government that wants to promote economic development and support families building long-term wealth should not impose a 40 percent tax on assets that have already been taxed previously.
Debate Intensifies After Farm Tax Controversy
The discussion around inheritance tax comes after the government faced major criticism from the farming community following changes introduced in the 2024 Autumn Budget.
At that time, proposals to remove certain inheritance tax exemptions for family farms sparked widespread protests across the country. Farmers argued that the changes could threaten the survival of multi-generation agricultural businesses.
After months of public pressure and political debate, the government eventually reversed some of the measures. In December, officials more than doubled the tax-free threshold for agricultural assets to £2.5 million, helping to ease concerns among farmers.
However, the controversy has kept the broader debate about inheritance tax alive.
Economic Impact and Administrative Costs
The IEA report also highlights the financial and administrative burden associated with collecting inheritance tax.
According to the report, the government spends around £66 million per year on administrative costs to collect the tax. Critics argue that this represents a significant economic inefficiency, especially considering the complexity families face when navigating legal and financial procedures during inheritance.
Rory Meakin, the author of the report, described the current system as arbitrary, complex, and economically damaging.
He argued that inheritance tax may discourage entrepreneurs from building businesses in the UK, as they fear that large portions of family wealth could eventually be lost through taxation.
Proposed Reforms to the System
While some economists support abolishing inheritance tax entirely, others suggest smaller reforms as a more realistic approach.
Possible policy changes include:
- Increasing the tax-free threshold
- Reducing the 40 percent tax rate
- Simplifying rules around gifts and transfers
Supporters of reform believe that even moderate changes could reduce complexity and encourage economic activity while still maintaining government revenue.
Conclusion
The debate over the UK’s inheritance tax system continues to intensify as economists, policymakers, and advocacy groups call for reform.
Critics argue that the current system places Britain among the highest-taxing nations on inherited wealth and may discourage investment, entrepreneurship, and long-term wealth creation.
While some experts believe the tax should be abolished entirely, others suggest reforms such as higher thresholds or lower rates.
As the Labour government faces growing pressure to boost economic growth and simplify the tax system, the future of inheritance tax remains a major topic of policy discussion.
