Top 100 Accounting companies in the United States (2026 list)

The accounting firms listed here are large organizations operating in the United States, providing a range of services such as audit, tax, and advisory. Many have a global presence or are part of international networks. Examples include KPMG, a global network of professional firms, RSM US LLP, focused on middle market clients, BDO USA, also serving middle market leaders, and Baker Tilly US, an advisory CPA firm with a coast-to-coast presence.

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 12, 2026.
