A list of the top 10 firms

Accounting Industry in the US – Overview

Accounting firms in the US saw strong growth in the five year period from 2013 to 2018, helped by rising equity markets, an increasing number of businesses, and overall economic growth. Revenues from US accounting services – including accounting, tax preparation, and payroll services – increased by more that 50%. In the next five years, higher activity in the financial markets and stronger aggregate private investment are expected to drive further growth for accounting firms in the US, which employ nearly 900,000 individuals.

 

Accounting Firms in the US

 

List of top accounting firms in the US

 

The US accounting industry is dominated by the Big Four accounting firms – Deloitte, PricewaterhouseCoopers, Ernst & Young, and KPMG – which reported combined revenues of around $128 billion in 2016. Deloitte generated $20 billion in revenues in the Americas and $38 billion worldwide.

 

The Big Four:

 

#1 Deloitte

Deloitte, the largest of the Big Four accounting firms in the US – and in fact the largest accounting firm worldwide – provides industry-leading assurance, consulting, tax, and risk and financial advisory services to many of the world’s most admired brands, including 80% of the Fortune 500 and more than 6,000 private and middle market companies. Deloitte’s primary business focus is on consulting, and it is considered to have the most hard-edged business orientation, as compared to the other three firms that place more public emphasis on things such as diversity and community involvement. As of 2015, Deloitte had an impressive annual growth rate of 8%.

 

#2 PwC

With offices worldwide, in more than 150 countries, and more than 223,000 employees, PwC helps organizations and individuals create the value they are looking for through a wide array of assurance, tax, and advisory services. In FY2016, PwC provided services to 422 companies in the Fortune 500. PwC is the leader among the Big Four in providing audit services.  In 2017, PWC’s assurance business segment generated more than $15 billion, approximately $5 billion more than Ernst & Young. It has made a move to substantially expand its consulting business with the acquisition of the consulting firm, Booz & Co.

 

#3 Ernst & Young

EY’s stated  purpose is to help build a better working world by performing high-quality audits. The firm’s top priority is to serve the public interest and grow the global EY network, with over 700 offices worldwide, successfully and responsibly. EY is notably growing its presence in the UK and focusing on its “global vision” of providing accounting services worldwide, with a stated emphasis on “diversity and inclusiveness”. After a few years of relatively slow growth, EY is back up to an annual growth rate of 5%+.

 

#4 KPMG

With 33% of revenues coming from audit and assurance, 27% from tax, and 40% from financial advisory, KPMG is committed to providing high-quality professional services in an ethical manner to entities that are listed on capital markets. KPMG serves more than 82% of the Fortune 500 and more than 80% of the Fortune 100. According to Martin Blackburn, UK People Director at KPMG, the company prides itself on being socially responsible and aiming to serve the “community at large”. KPMG is the smallest of the Big Four accounting firms in the US, but continues to grow through business expansion and acquisitions.
