Let us discuss to inform you about these Big 4 accounting firms, what services do the Big 4 actually provide and how you can build a career in these Big 4s.

What are the Big 4 Accounting Firms?

Talking about what are the Big 4 accounting firms, we are referring to the four largest accounting and audit firms in the world, namely Deloitte, PwC, EY, and KPMG. Big, not in size but in influence, is how companies across the world report their finances, follow regulations, and make strategic decisions.

Operating in almost every country, the Big 4 accounting firms serve every major company, from banks and tech giants to manufacturing companies and startups. Their work shapes global financial stability because they audit most of the world’s leading corporations.

Big 4 companies are not just accounting firms, they manage much more work, such as in audit, tax, consulting, advisory, risk, forensics, cybersecurity, sustainability, and even AI-powered business transformation. This is why students from commerce, finance, engineering, economics, and even data science aim to work here.

Working in the Big 4 shapes your career. It means learning fast, getting exposure to different industries, and building a brand name that stays with you for life. That is why these firms still remain the top dream workplaces for professionals in 2026.

Why Are They Called the Big 4?

They are called Big 4 accounting firms (Deloitte, PwC, EY, and KPMG) not only because of their size but also because of their immense leadership role in shaping global auditing standards, tax frameworks, and corporate governance practices. 

Their decisions, research, and methods influence how businesses operate across the world. Actually, they lead the industry in size, revenue, workforce, and global reach. So, the key reasons they are called the Big 4 companies are as follows:

Revenue

In terms of revenue, these Big Four consulting firms earn the highest revenue in the accounting world. More than any other firm globally, which puts them at the top of the industry.

Employer

Together, the Big 4 accounting companies have more than a million employees, making them the biggest employers in the global finance and consulting ecosystem.

Dominate Auditing

Fortune 500 companies, major banks, tech giants, and MNCs trust these firms for their major accounting, auditing and financial reporting.

Biggest Influencers

Research and practices of Big 4 accounting and audit firms shape global standards for auditing, taxation, and corporate governance.

Consolidation

The accounting industry once had the “Big 8,” but their mergers and the collapse of Arthur Andersen reduced the number to four.

The Enron Collapse: What Really Happened?

Enron, the biggest scandal in the accounting world in history. It is a story that changed the global audit industry forever and shaped the Big 4 accounting companies we know today.

Thus, the whole saga commenced during the 90s, when the financial giant Enron was the most innovative in the USA. This was a gigantic company in the energy sector that was at the top of the world for its fast-paced growth and visionary leadership. The stock market and investors were its fans, and even the press was on its side, to say the least. At first sight, Enron was nothing but a paragon of success.

Nevertheless, a dark side was there to the company’s bright image.

The executives at Enron resorted to the convenient yet unethical means of creative accounting to cover up their huge losses. They set up completely fictitious companies to offload their debts away from the main balance sheet. The company was depicted as profitable in the books, but in fact, it was buried under financial problems.

And Arthur Andersen, then one of the biggest audit firms, failed to disclose the fraud. Andersen was the one who had to verify Enron’s financial statements and guarantee that the numbers were correct. At times, even papers were destroyed when the inquiry started. It all came down in the year 2001. The reality was clear. Enron went bankrupt. The investors’ losses were counted in billions. The workers lost their jobs, their savings, and their trust in the system.

The firm Arthur Andersen, which was once known as one of the best consulting firms of all time, was declared guilty of impeding justice. The clients moved away, the partners quit, and the firm was closed down. It was a shocking event for the entire world, and the Big 5 were now the Big 4 accounting firms.

The Enron scandal forced governments to bring stricter auditing rules and higher ethical standards. It became the turning point that reshaped the accounting industry and taught the world a lesson about transparency and integrity.
