Spotlighting the Nation's
Top 500 CPA Firms

The Annual List: Comprehensive Rankings

Every year, INSIDE Public Accounting ranks the top 500 CPA firms in the nation based on net revenue, from the multi-billion-dollar Big 4 to No. 500. 

The rankings are the most anticipated announcement of the year for IPA clients and subscribers of our data-driven practice management blogs. Leaders are eager to learn whether their firms have inched higher up the list, as the rankings change dramatically from year to year with the rapid pace of both organic growth and M&A-fueled expansion.

IPA’s analysis of the IPA 100, 200, 300, 400 and 500 firm groupings help identify and contextualize the challenges and opportunities of the previous year and describe how firms have pivoted to adjust.
