This selection of accounting firms in North America primarily features large, established companies. Many of these firms offer a comprehensive suite of services including assurance, tax, and advisory, catering to a diverse clientele from middle-market businesses to global enterprises. Their focus often includes cultivating strong client relationships and providing industry-specific expertise.

Among these, KPMG stands out as a global network offering audit, tax, and advisory services across 146 countries. RSM US LLP and BDO USA, both headquartered in Chicago, provide assurance, tax, and consulting services, with RSM focusing on middle market clients. MNP, based in Calgary, is a national accounting, tax, and business consulting firm in Canada. A notable pattern is the concentration of headquarters in major US cities, particularly Chicago and New York.

## 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 14, 2026.
