Here are the 75 largest accounting firms in Houston

The largest accounting firms in Houston employ more than 10,000 local accounting professionals in the Texas counties of Austin, Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, San Jacinto and Waller. The online version of this ranking expands beyond what appears in print; another 55 accounting firms are included in our digital rankings, in addition to the 20 featured in this week's print edition. This week's List marks a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ's footprint — this year alone. Information on The List was obtained through HBJ research or supplied by individual firms through questionnaires that HBJ could not independently verify. In case of ties, firms are ranked by local CPAs, then listed alphabetically if ties remain. Additionally, accounting firms that did not respond to employment surveys but were still included on this year's List are sorted by estimated total employment figures derived from HBJ archives; annual filings with the U.S. Department of Labor; and other firm-specific resources.
