RSM US

What RSM US does

RSM US LLP is the U.S. member firm of RSM International and the fifth-largest accounting firm in the United States, providing assurance, tax, and consulting services to middle-market companies with revenues typically ranging from $50 million to $1 billion+. Founded in 1926 and headquartered in Chicago, the firm operates across 77 U.S. cities, 6 Canadian locations, an El Salvador delivery center, and four Indian cities (Gurugram, Hyderabad, Bengaluru, Kolkata) with approximately 3,800 India-based professionals. The combined U.S. and Canadian workforce exceeds 17,900 partners, principals, and employees, and RSM US revenue is disclosed at approximately $4 billion, contributing to a $5 billion+ transatlantic partnership with RSM UK effective January 1, 2026.

The firm operates a hybrid professional services and technology reseller model across three core service lines: assurance/audit, tax advisory and compliance, and consulting (including digital transformation, cybersecurity, and transaction advisory). Technology is embedded throughout via proprietary platforms — RSM Luca (digital audit ecosystem with the Ask Luca generative AI tool), myRSM Tax (AI-powered tax technology), RSM Defense (managed security integrated with SailPoint), and CorporateSight/FamilySight/PartnerSight analytics platforms — alongside strategic technology alliances with Microsoft, NetSuite, Salesforce, ServiceNow, BlackLine, Sage Intacct, and Boomi. The VAR/software reseller business alone generated $799.79 million in FY2024, ranking #1 on Accounting Today's VAR 100 list.

RSM US pursues a relationship-based enterprise field sales motion targeting middle-market organizations, supplemented by technology partner co-marketing and integrated delivery centers providing cost-effective nearshore capacity. Revenue mechanics are engagement-based with customized pricing; the firm does not disclose public pricing. A $1 billion three-year investment under the RSM100 centennial campaign is being directed toward AI and digital capabilities, alongside strategic partnerships with Allvue (Agentic AI Capital Operating Model for private capital), Akur8 (insurance regulatory intelligence), Sylogist (public sector cloud), FloQast (accounting workflow automation), and SailPoint (identity security). Unlike several competitors that have taken private equity investment, RSM has self-funded its expansion through Project Bamboo while completing the transatlantic merger.
