The idea of a wealth tax on the UK's super-rich is gaining traction, with academics suggesting it could raise a substantial £10 billion annually. This proposal, championed by Gabriel Zucman and Ben Tippet, targets households with over £100 million in wealth, affecting fewer than 1,000 families. The tax, at a minimum 2% rate, aims to address the growing wealth inequality and fund public services. Andy Burnham, the new prime minister, is considering this measure as part of his 10-year plan, despite his advisors' focus on capital gains tax. The tax would require HMRC to calculate the accumulated wealth of the UK's richest families, including property, businesses, and pension wealth, to prevent large-scale tax avoidance. Zucman's research highlights the ability of the wealthy to avoid current taxes through holding companies and family transfers. Tippet argues that a well-designed minimum tax on the very wealthy is a realistic and targeted reform, addressing administrative complexity and revenue generation. The proposal also includes a 10-year tax payment rule for those leaving the UK, a measure to deter tax evasion. The global trend towards wealth taxes is evident, with New York City's mayor advocating for a broader approach. The G20 meeting in South Africa emphasized the need to address inherited wealth inequality, with a proposed 2% tax on billionaires' wealth. However, critics argue that historical wealth taxes had low thresholds and exemptions, leading to avoidance and political opposition. The key to successful wealth taxes, according to the report, lies in focusing on the ultra-wealthy, applying to a broad asset base, and ensuring strong administrative enforcement. This proposal raises important questions about the role of taxation in addressing wealth inequality and the potential impact on the UK's tax system and society.
