Accounting Industry Financials

The US accounting and tax preparation industry includes about 90,000 firms with combined annual revenue of $65 billion. Large companies include PricewaterhouseCoopers, KPMG, Deloitte Touche Tohmatsu, Ernst & Young, and H&R Block. Despite concentration at the top, the industry is fragmented: the 50 largest companies hold less than 50 percent of the market. Most firms are small, with annual revenue under $1 million; large local firms may have revenue of $5 to $10 million.

Using the 2002 Census Bureau Economic Census, Hoover's has generated an industry financial summary for the Accounting industry.
