Wealth Tax on UK Super-Rich Could Raise £10bn Annually 2026

A proposed wealth tax on the UK's super-rich households could raise £10bn a year, according to academics who urged Andy Burnham to include the measure in his plans to make tax fairer and fund better public services. The study, led by Gabriel Zucman and Ben Tippet, suggests a 2% minimum charge on households with over £100m in wealth, affecting fewer than 1,000 of the richest UK families.

How the Wealth Tax Would Work

The proposed wealth tax would require HMRC to calculate accumulated wealth including property, private businesses, pension assets, art, land, and charitable holdings under the control of the wealthiest households. This targeted approach aims to ensure billionaires pay tax rates comparable to ordinary citizens.

Burnham has hinted that a wealth tax could be part of his 10-year plan for the UK, though advisers have also focused on raising capital gains tax to match income tax rates. The prime minister emphasized fairness without demonizing any group.

Key Benefits of the Wealth Tax

• Raises £10bn annually for public services like healthcare and education
• Affects fewer than 1,000 households, minimizing economic disruption
• Reduces runaway inequality by targeting extreme wealth
• Aligns with global trends in wealth taxation

Wealth Tax Comparison: UK vs Global Proposals

Gabriel Zucman, known as the architect of the global wealth-tax movement, emphasized that the objective is not a broad-based tax but a focused levy on extreme wealth. The report argues this can dampen runaway inequality while raising meaningful revenues.

Political Context and Challenges

Andy Burnham has stated he wants to avoid creating new divisions in society, but acknowledges the need for greater fairness. The proposal faces opposition from those who argue it could discourage investment and drive wealth abroad. However, proponents point to successful wealth taxes in countries like Switzerland and Norway.

The new prime minister will lay out tax and spending plans soon, with the wealth tax proposal likely to spark debate. Critics question HMRC's capacity to accurately value complex assets like private businesses and art collections.
