INSIDE Public Accounting (IPA) is proud to present its first ranking of the nation’s largest 400 accounting firms – the only one of its kind. The IPA 400 firms was listed in the October issue of IPA and picked up where August’s IPA 300 issue left off, ranking firms from No. 301 to No. 400. To see the full list, visit IPA’s website.

This definitive list was developed by gathering information from more than 550 firms that completed IPA’s Survey and Analysis of Firms. Many professional associations also aided in the search for firms to add to the list, which IPA plans to publish annually.

For the most recent fiscal year, IPA 400 firms range in size from $4.55 million to $9.9 million, and from 20 to 80 staff. These firms employee more than 4,000 total staff across the nation.

For more than two decades years, IPA has sustained a tradition of groundbreaking excellence by compiling the annual IPA 100, 200 and 300 accounting firms and the IPA Best of the Best. As the profession continues to grow and evolve, IPA will evolve with it.

Highlights of the IPA 400: 

  • 3.7% – Average organic revenue growth
  • 2.0% – Average organic net income growth
  • 11.8% – Average staff turnover
  • $76,065 – Average pay per professional staff
  • $391,096 – Average equity partner compensation
