# Accounting firms headquartered in the United States

Tamtam tracks 387 accounting firms headquartered in the United States. This list ranks the 100 largest by number of employees on LinkedIn, led by Deloitte, KPMG and KPMG US. Their median headcount is 1,167. Half of them were founded in 1977 or later. The most common headquarters are New York (11), Chicago (9) and Atlanta (4).

These are large professional services and financial services firms operating in the United States, primarily in accounting, tax, and advisory services. Many of these companies serve the middle market and have a global presence. Several firms, such as Deloitte and KPMG, are global professional services firms. H&R Block and Jackson Hewitt Tax Service Inc. specialize in tax preparation services. RSM US LLP and BDO USA focus on assurance, tax, and consulting for middle market clients.

A notable pattern is the concentration of headquarters in Chicago, with RSM US LLP, Grant Thornton (US), BDO USA, Baker Tilly US, and Crowe all based there. This suggests a significant cluster of accounting and professional services firms in the city. The founding dates range from 1845 (Deloitte) to 2012 (CLA), indicating a mix of long-established and relatively newer large companies.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
