Controversies Surrounding the Big Four Accounting Firms

The “Big Four” accounting firms—Deloitte, Ernst & Young (EY), KPMG, and PricewaterhouseCoopers (PwC)—occupy a dominant position within the global audit and professional services market. Entrusted with safeguarding the integrity of financial reporting for many of the world’s largest corporations, these firms play a critical role in maintaining public confidence in capital markets. However, over the past decade, the Big Four have been subject to sustained criticism and regulatory scrutiny arising from audit failures, conflicts of interest, ethical breaches, and concerns regarding their influence and organisational culture. This report examines the principal controversies associated with the Big Four and evaluates their implications for the auditing profession and wider society.

Audit Failures and Regulatory Sanctions

One of the most significant sources of criticism directed at the Big Four relates to high-profile audit failures linked to major corporate collapses. These cases have raised serious questions about audit quality, professional scepticism, and the effectiveness of regulatory oversight.

A prominent example is the collapse of the German payments company Wirecard in 2020. EY, which had audited the company for several years, faced intense scrutiny after Wirecard admitted that €1.9 billion of reported cash did not exist. The scandal prompted investigations by German regulators into whether auditors had failed to adequately challenge management representations and identify material misstatements.

In the United Kingdom, the failures of companies such as Carillion, BHS, and Thomas Cook similarly exposed weaknesses in auditing practices. KPMG’s audits of Carillion, PwC’s role in BHS, and EY’s work for Thomas Cook were all criticised by regulators and parliamentary committees for insufficient challenge of management assumptions and inadequate assessment of going concern risks. These collapses resulted in substantial job losses and significant costs to taxpayers and pension schemes.

More recently, PwC’s China practice received a record regulatory fine and a six-month suspension in 2024 for deficiencies in its audits of Evergrande, the heavily indebted property developer whose collapse sent shockwaves through global financial markets. The sanction reflected failures to identify major financial misstatements over a prolonged period.

Conflicts of Interest Between Audit and Consulting

A long-standing concern surrounding the Big Four is the potential conflict of interest created by their provision of both audit and non-audit services to the same clients. While audit engagements require independence and objectivity, consulting services are often highly lucrative and dependent upon maintaining positive client relationships.

Critics argue that this dual role may compromise auditors’ willingness to challenge management rigorously, thereby weakening audit quality. In response, regulators—particularly in the United Kingdom—have called for greater operational separation between audit and consulting divisions. Proposals have included ring-fencing audit practices to ensure they are managed, governed, and remunerated independently from advisory arms, thereby reducing commercial pressures that could undermine auditor independence.

Misconduct and Ethical Breaches

Beyond audit quality, the Big Four have faced a series of ethical scandals that have damaged public trust in the profession. Notably, several firms have been fined by regulators for widespread cheating on internal training and ethics examinations.

In 2022, EY was fined US$100 million by US authorities after it was revealed that employees had cheated on professional exams and that the firm had subsequently misled investigators. This represented the largest penalty ever imposed on an audit firm by the US Securities and Exchange Commission. KPMG received a US$25 million fine in 2024 for similar misconduct, including providing false information to regulators. Deloitte and PwC were also sanctioned in 2025 for exam-related cheating within their Dutch operations.

The firms have additionally been criticised for their involvement in aggressive tax avoidance arrangements. Although such schemes are often technically legal, revelations such as the “LuxLeaks” exposed the extent to which the Big Four assisted multinational corporations in minimising tax liabilities, thereby contributing to public perceptions that they enable practices which undermine the fairness of tax systems.

A particularly damaging episode occurred in Australia, where PwC was implicated in the misuse of confidential government information. Partners were found to have shared sensitive tax policy details with corporate clients, enabling them to circumvent proposed legislation. The scandal resulted in substantial fines, reputational damage, and the resignation of senior leadership, including the firm’s chief executive.

Influence and Organisational Culture

The Big Four have also been criticised for their considerable influence over public policy and regulation. The so-called “revolving door” phenomenon—where former partners take up senior roles in regulatory bodies or government—has raised concerns about regulatory capture and the independence of oversight institutions.

Internally, the firms have faced growing scrutiny regarding workplace culture. Reports of excessive working hours, high stress levels, and limited progress on diversity and inclusion have prompted calls for reform. While the Big Four have publicly committed to improving employee wellbeing and equality, critics argue that meaningful cultural change has been slow and uneven.
