INSIDE Public Accounting Releases Its Annual Rankings and Performance Metrics of the Nation’s Largest Public Accounting Firms

INSIDE Public Accounting (IPA), the award-winning newsletter for the public accounting profession, has released its annual financial performance analysis and rankings of the nation’s largest public accounting firms. New in 2022 is the IPA 500, those firms ranked from No. 401 to No. 500.

The annual IPA national practice management survey draws participation from nearly 600 of the largest firms. The leader in data collection for the public accounting profession since 1990, IPA boasts a 92% return rate of participating firms.

Rankings of The IPA Top 100 Firms

Now in its 32nd year, the annual list is made up of the Big 4, which collectively generated more than $70.8 billion in U.S. revenue, and 96 national, regional and local firms. These 96 firms range from Chicago-based RSM US ($3.3 billion) at No. 5, to Columbus, Ohio-based GBQ Partners LLC ($44.5 million) at No. 100.

IPA also ranks and provides key data on the IPA Top 400, which ranks firms from No. 101 ($43.6 million) to No. 400 ($8.4 million).

The Inaugural IPA 500 Firms

This year, IPA is excited to launch the first-ever ranking of the IPA 500 (Nos. 401-500), which range in size from $8.4 million to $3.9 million and account for $613 million in revenue annually. The annual rankings and accompanying analysis paint a comprehensive picture of the state of the public accounting profession.

Demographics of the Public Accounting Profession – 2022

The Big 4 – Deloitte, PwC, EY and KPMG – collectively make up nearly 70.7% of the total revenue of this year’s IPA 100. Due to their size, IPA excludes metrics of the Big 4 in its in-depth analysis of the profession to provide all other accounting firms with meaningful comparative practice management data. The next 96 firms represent $29.4 billion in total revenues and employ more than 125,000 staff. Excluding the Big 4, 51 firms represented in the IPA 100 boast annual revenues exceeding $100 million.

  • Average equity partner billing rates are now at $494 per hour for the IPA 100.

“Despite the many headwinds of change and disruption facing the US economy, the nation’s largest public accounting firms are facing unprecedented demand for their services,” says Mike Platt, principal with INSIDE Public Accounting. “As client companies maneuver to navigate supply chain disruption, staffing shortages, inflation and return-to-work policies post-COVID, the nation’s largest accounting firms are helping to guide the way, truly becoming hands-on advisors to their clients and moving significantly beyond traditional compliance work.”

The full analysis of the nearly 600 public accounting firms will be published in September in IPA’s annual National Practice Management Benchmarking Report.
