The long-held ambition of Britain's super-rich being made to contribute their fair share has taken a significant step forward. A pioneering study suggests that a modest 2% wealth tax could rake in £10 billion annually, levelling the playing field for billionaires and bringing relief to hard-pressed public services. As Prime Minister Andy Burnham prepares to unveil his government's economic blueprint, academics are urging him to seize this opportunity to rebalance the nation's finances and address growing income inequality.
Professor Gabriel Zucman of the Paris School of Economics and Ben Tippet, a lecturer in economics at King's College London, have presented compelling research that proposes taxing households with more than £100 million in assets. This would apply to fewer than 1,000 ultra-wealthy families, effectively creating a new tier of taxation that ensures billionaires contribute a similar rate as the general population.
Prime Minister Burnham has signalled his willingness to explore a wealth tax, although his team is also mulling over increasing the capital gains tax threshold in tandem with income tax rates. The PM's words on fair taxation have been cautious: "We need to ensure fairness without demonising one group." By tackling the issue of wealth inequality head-on, he could make good on this promise and demonstrate a commitment to levelling the economic playing field.
HMRC would be responsible for calculating the total accumulated wealth of Britain's wealthiest families. This comprehensive assessment would encompass diverse assets such as property, private businesses, pension wealth, art, land, and charitable assets under their control. The report highlights that this targeted approach sidesteps common criticisms of broader wealth taxes, namely administrative complexity and valuation challenges, given the small number of households involved.
To prevent tax avoidance, the plan includes a provision requiring wealthy families to pay the tax for at least ten years after relocating from the UK. This would eliminate the incentive to move abroad solely to evade the charge, mirroring similar measures implemented by cities like New York and international bodies such as Germany and Brazil advocating for a global minimum tax on billionaires to combat poverty.
