Who are the Big Four Accounting Firms?
The Big Four accounting firms refer to Deloitte, PricewaterhouseCoopers (PwC), KPMG, and Ernst & Young. These firms are the four largest professional services firms in the world that provide audit, transaction advisory, taxation, consulting, risk advisory, and actuarial services. The Big Four perform audits on the majority of public companies and private companies throughout the world.
Deloitte Touche Tohmatsu Limited, more commonly referred to as Deloitte, is a UK-incorporated international professional services firm with headquarters in New York City. Widely regarded as one of the top firms within the Big Four, Deloitte is well known for its audit, tax, risk, financial advisory and consulting services.
With offices in more than 100 locations worldwide, it reported the highest revenue among the Big Four accounting firms in 2016 and is considered the sixth largest privately owned organization in the United States.
