Fat Cat Tax: Why Tackling Extreme CEO Pay Gaps Matters

Growing attention is turning to the idea of a “Fat Cat Tax” in response to these widening pay gaps. The proposal centres around applying an additional corporate tax surcharge to companies that choose to pay executive directors many times more than their workforce. Instead of setting a strict limit on pay, this system would connect tax costs to very high pay differences, with bigger taxes applied as the difference between top salaries and average worker pay gets larger. 

Supporters argue this approach targets corporate behaviour rather than individual income while encouraging firms to either rein in excessive remuneration or invest more in wages, training, and long-term growth. With transparency measures already in place and executive pay still rising year after year, the Fat Cat Tax is increasingly seen as a corrective tool designed to restore balance, rebuild trust and ensure that corporate success delivers broader economic benefits.

The Scale of Executive Pay Gap in UK

The High Pay Centre’s annual “Fat Cat Day” analysis illustrates how extreme the executive pay gap in UK pay has become. Their 2026 calculations found that:

• Median FTSE 100 CEO pay: The typical chief executive earned £4.22 million in 2025 (excluding pension), a 113‑to‑1 ratio relative to a full‑time worker earning £37,430.
  
• Average FTSE 100 CEO pay: Mean pay was even higher at £4.40 million, still about 113 times the median full‑time wage. CEOs earned a median worker’s annual salary by midday on 6 January 2026.
  
• High outliers: Individual companies show far bigger disparities. Aerospace group Melrose paid its CEO nearly £59 million, a staggering 1509‑to‑1 ratio, while some retailers such as Tesco paid their chief executives over 400 times the typical employee salary.

What People Think

The public strongly supports closing these gaps. Several surveys show overwhelming support for limiting executive pay and demanding higher wages for frontline staff:

• A High Pay Centre and Survation poll found that 62% of respondents believe CEOs should not be paid more than 10 times their typical employee, while only 3% thought pay gaps above 50 times are acceptable.
• In a 2025 ShareAction poll, 70% of UK adults said it is unacceptable for CEOs to earn 100 times more than their lowest‑paid staff, and 93% of shoppers at retailer Next said employers should pay the real Living Wage rather than just the legal minimum.
• The High Pay Centre notes that the majority of people think CEOs should be paid no more than 20 times as much as their typical employees and that wider pay gaps damage employee morale, engagement, and corporate reputation.

This disconnect between boardroom rewards and public expectations undermines trust in business and fuels calls for reform. Even many investors are pressing for fair pay policies, as evidenced by resolutions filed at annual general meetings demanding living‑wage commitments.

The Proposed Fat Cat Tax

To tackle these extreme inequalities, the High Pay Centre and the Equality Trust propose a “Fat Cat Tax”. The policy would add a surcharge to corporation tax payable by any firm whose CEO’s single‑figure remuneration exceeds a multiple of the median UK worker’s salary. Key features include:

• Progressive thresholds: The surcharge would start when the CEO‑to‑worker ratio exceeds 10:1 and increase to 50:1, 100:1, 200:1, and 500:1.
• Ring‑fenced revenues: Tax receipts would be earmarked for education and early years provision, investing in social mobility and addressing inequality at its roots.
• Incentives not prohibitions: Companies could still pay high executive salaries if they choose, but the tax would create a clear financial cost for extreme pay gaps. The policy aims to encourage boards to share corporate wealth more fairly or raise wages for lower‑paid staff.

Why This Matters

Extreme pay gaps are not just unfair; they carry broader economic and social costs:

• Curb UK income inequality: Evidence compiled by the Equality Trust shows that high income inequality is linked to financial crises, increased debt and inflation. Societies with greater equality typically experience longer periods of sustained growth, whereas inequitable economies are more vulnerable to cycles of boom and bust.
• Lower productivity: Studies indicate that reducing the wages of low-paid workers lowers their productivity more than increasing the pay of high-paid workers raises theirs. Whether employees perceive their pay as fair affects their productivity. Therefore, workers perceive excessive CEO pay as unfair, which can negatively impact productivity and commitment.
• Health and wellbeing: Living in an unequal society produces stress and status anxiety. Research compiled by the Equality Trust finds that more equal societies have a longer life expectancy and lower rates of mental illness, obesity, and infant mortality. Greater inequality is associated with higher levels of depression and schizophrenia.
• Corporate trust and product quality: Surveys compiled by the Equality Trust link excessive CEO pay to lower trust in corporations, bad relations with employees, worse job satisfaction and even higher inflation. These factors damage long‑term corporate performance.

Building a Fairer Future

The Fat Cat Tax proposal highlights growing dissatisfaction with a system that funnels corporate wealth to a privileged few. Polls indicate that most Britons support limiting CEO pay to modest multiples of average wages and that many consumers are prepared to boycott companies that fail to pay a real living wage. At the same time, decades of UK income inequality and wage stagnation mean that millions of households have seen little improvement in their living standards.

A tax surcharge for companies with very high pay ratios would not fix inequality on its own, but it would send a strong message that businesses should help society as a whole. By disincentivising excessive remuneration, encouraging higher wages for the lowest paid, and generating revenues for education and early years programs, the policy could make a real difference. Ultimately, businesses thrive in societies where workers are healthy, educated and motivated. Closing the gap between the boardroom and the shop floor is in everyone’s interests.
