What Are Big 4 Accounting Firms?
The largest accounting and audit firms in the world are called the Big 4, which is considered as the Mecca of accountants. They are so large that their combined revenue exceeded $210 billion in recent years.

Which Companies Come Under the Big 4?
The largest accounting and auditing firms in the world, commonly known as the Big 4, are:
- Deloitte
- PricewaterhouseCoopers (PwC)
- Ernst & Young (EY)
- KPMG
The global accounting industry wasn’t always dominated by just four firms. It began with the Big 8, which controlled most of the audit and consulting market worldwide.
This changed in 1989 when major mergers reduced the Big 8 to the Big 6. Ernst & Whinney merged with Arthur Young to form Ernst & Young, while Deloitte Haskins & Sells merged with Touche Ross to become Deloitte.
In 1998, Price Waterhouse merged with Coopers & Lybrand to form PricewaterhouseCoopers, reducing the number to the Big 5.
Finally, in 2002, the collapse of Arthur Andersen following the Enron scandal led to the emergence of today’s Big 4: Deloitte, PwC, EY, and KPMG.
