A proposed 2 per cent annual wealth tax on assets exceeding £10 million, championed by economist Gary Stevenson, is set to generate billions for the Treasury from those deemed capable of affording it. According to estimates, this levy could raise an additional £6.8 billion annually, significantly bolstering the UK's public finances.
Stevenson's argument focuses on addressing wealth inequality, which has been a growing concern in the UK. His proposal suggests that such a tax could be a straightforward solution to a complex problem, and his approach has resonated with a broad audience due to its clear communication. However, critics argue that while the concept is appealing, its underlying policy may struggle to withstand the intricacies of the UK's economic and political landscape.
The distinction between Stevenson's wealth tax and other taxes on dividends or capital gains lies in its focus on the total stock of assets an individual owns, rather than returns generated. For instance, two individuals with £10 million in assets would pay the same 2 per cent wealth tax, regardless of whether their assets generate a 10 per cent or 3 per cent annual return. This disparity raises questions about fairness and consistent revenue generation, as a wealth tax does not inherently guarantee a steady flow of income to the Treasury.
Moreover, concerns have been raised that a wealth tax could deter investment in the UK. Factoring in existing taxes such as corporation tax (25 per cent), dividend tax (around 39.35 per cent), and capital gains tax (24 per cent for most assets), the total tax burden on investment returns could become substantial. This could lead to capital flight, with wealthy individuals reorienting their investments towards more favourable jurisdictions. It's estimated that approximately 80 per cent of ultra-wealthy assets are held in financial instruments such as bonds and securities, which are highly mobile.
A significant challenge for policymakers lies in accurately understanding and tracking how wealth is held, its location, and the returns it generates. Wealth can be diversified across numerous vehicles, including private funds, trusts, overseas investments, and even tangible assets like artwork. Without a comprehensive understanding of these facets, setting an appropriate tax rate that ensures consistent revenue while avoiding unintended economic consequences becomes incredibly difficult. Some suggest that a 'zero per cent wealth tax' could be a starting point, compelling wealthy individuals to declare their assets and build a clearer picture of the UK's wealth landscape before considering a more punitive approach.
