Over 120 millionaires demand higher wealth taxes

An open letter signed by more than 120 UK millionaires calling on the government to increase taxes on extreme wealth has reignited debate across the tax and accounting sectors. Organized by campaign group Patriotic Millionaires UK, the letter urges the Prime Minister to reform the tax framework so that accumulated assets carry a greater share of the tax burden relative to employment income.

For UK accounting firms and wealth managers, this high-profile intervention touches directly on technical discussions surrounding capital taxation, private client planning, and government revenue modeling.

Core Proposals and Financial Impact

The signatories are advocating for targeted fiscal changes rather than broader increases on earned income. Their primary policy proposals include:

1. An Annual Wealth Tax: Introducing a 2% annual tax on individual personal wealth exceeding £10 million. Campaign models estimate this single measure could raise roughly £24 billion annually.

2. Capital Gains Tax (CGT) Reform: Equalizing Capital Gains Tax rates with standard Income Tax rates. Proponents suggest this realignment, alongside closing specific exemptions, could generate an additional £12 billion to £15 billion per year.

3. Targeted High-Net-Worth Levies: Broader proposals floating within academic circle assessments suggest even a narrower 2% minimum charge on ultra-high-net-worth households (those holding over £100 million in wealth) could bring in around £10 billion annually, affecting fewer than 1,000 households nationwide.

What This Means for UK Practitioners and Clients

While voluntary contributions are already permitted under current Treasury mechanisms, private client advisors point out that statutory systemic changes present distinct technical and advisory considerations:

• Valuation Complexities: Unlocking revenue through a annual wealth tax requires precise, regular valuations of illiquid assets, privately held businesses, real estate portfolios, and alternative investments. In practice, this would significantly increase the compliance and reporting responsibilities for accounting practices representing high-net-worth individuals (HNWIs).

• Capital Flight and Behavior Risks: Advisors caution that sudden structural shifts in wealth taxation historically prompt behavioral adjustments, including tax residency planning, accelerated gifting strategies, or relocation of capital to foreign jurisdictions.

• Focus on CGT Alignment: Rather than a brand-new standalone wealth tax, industry specialists note that tax policy shifts often start with incremental changes, such as narrowing CGT reliefs, altering non-domiciled status rules, or adjusting inheritance tax thresholds.

Treasury representatives have responded to the campaign by noting that formal tax policy decisions remain reserved for official Budget statements, leaving advisory professionals to closely monitor upcoming fiscal announcements.
