The number of millionaires in the UK has seen a dramatic decline, sinking to its lowest point since the aftermath of the 2008 financial crisis. Recent data from the Adam Smith Institute (ASI) reveals a staggering 7 per cent fall, with the tally now standing at just 442,000 high-net-worth individuals (HNWIs). This shift, attributed to dwindling asset values, the emigration of affluent individuals, and a low household saving rate, raises pressing questions about the country’s attractiveness as a domicile for the wealthy.
Declining Wealth: Key Drivers
Several factors have contributed to this noteworthy reduction in millionaires. The ASI’s tracker, which utilises data from the Office for National Statistics, indicates that the decrease is largely driven by falling asset prices and a notable trend of HNWIs relocating abroad. The tracker assesses wealth using “constant prices” to account for inflation and currency fluctuations, defining a millionaire as someone with assets exceeding £1 million across various asset classes, including real estate, investments, and savings.
The think tank, known for its right-leaning perspectives, has voiced concerns about the UK’s diminishing appeal to high earners. They have called for significant policy reforms, including the abolition of inheritance tax, a phased removal of capital gains tax, and a revamp of the non-domiciled tax regime. Such proposals, while potentially beneficial for the wealthy, could lead to serious discussions regarding the implications for government revenue.
The Fiscal Landscape: Tax Implications
In the 2023-24 financial year, the UK government garnered £7.2 billion from inheritance tax receipts, constituting less than 1 per cent of its total revenue. However, forecasts indicate that this figure could escalate to £8.5 billion by 2025-26 and soar past £14.5 billion by 2030-31. This projected increase is attributed to a combination of frozen thresholds, fiscal drag, and the impending inclusion of pension assets in inheritance tax calculations.
Critics of wealth taxation have pointed to the failures experienced in countries like France, Sweden, and the Netherlands, where such measures have resulted in poor tax yields and a marked exodus of wealthy citizens. The ASI’s report emphasises that the ongoing departure of millionaires could have dire consequences for the UK economy, reducing capital availability for businesses and stifling job creation.
Voices from the Economic Frontline
Andrew Griffith, the shadow secretary of state for business and trade, echoed the grave concerns raised by the ASI. He stated, “Regardless of their personal circumstances, the decline in millionaires should alarm everyone. Fewer wealthy individuals mean a reduced tax base and diminished prospects for job creation and business development.”
Economic experts have also weighed in on the issue, cautioning that the current trend should not be dismissed as a victory for any political faction. Mitchell Palmer, an economist at the ASI, warned, “Each millionaire that departs represents a loss of capital, international ties, and entrepreneurial zest within the UK economy. Anti-wealth measures like wealth taxes will only exacerbate these challenges.”
The report notably lacked commentary from government representatives, including business secretary Jonathan Reynolds, which has left some analysts questioning the government’s strategy regarding high earners.
Why it Matters
The decline in the number of millionaires in the UK signals a troubling trend that could have far-reaching implications for the economy. With fewer high-net-worth individuals, the potential for capital investment and job creation diminishes, posing challenges for long-term economic growth. As the government grapples with this issue, the need for policies that enhance the UK’s appeal to affluent individuals becomes increasingly urgent. A failure to address these concerns may not only hinder economic progress but could also foster a climate where talent and wealth continue to migrate away from British shores.
