UHY Buys St. Louis Tax Firm, Third Deal in 30 Days [US]
UHY has acquired Larson Tax Partners, a St. Louis tax and advisory practice, as part of an acquisition spree backed by institutional capital. The deal marks UHY's third in 30 days, following additions in upstate New York and Albany.
Larson Tax Partners was established in 2021 within Larson Financial Holdings and specialises in tax planning and compliance for closely held businesses and affluent families. The acquisition applies only to Larson Tax Partners and does not include other Larson-affiliated entities.
UHY now operates over 40 offices across the United States with approximately 2,000 professionals and nearly $500 million in revenue. The firm ranks 29th on Accounting Today's top 100 list and has explicitly stated ambitions to reach top 15-20 status and surpass $1 billion revenue within five years.
The expansion strategy is funded by UHY's first institutional capital investment: Summit Partners injected capital in December 2025 specifically to support both organic and acquisition-driven growth. Steven P. McCarthy, Chairman and CEO, told media the firm completed three deals in 2025 alone, targeting smaller practices where older CPAs are approaching retirement.
Recent acquisitions include CMJ LLP in Queensbury, New York (focused on construction and financial services), Cruden & Company in Albany, and Manley Garvin in South Carolina. The firm has flagged Boston, New York, and Ohio as expansion priorities.
Beyond acquisitions, UHY is centralising operations after years of regional management. The firm is transitioning merit-based compensation from regional to firm-wide models, aligning partner incentives with overall profitability rather than local performance. This structural shift supports integration of acquired firms.
Paul Larson noted the deal provides clients with "broader national resources" while maintaining personalised service. For context: this is what institutional capital looks like in action. Three deals in 30 days, regional consolidation, and a stated target to double revenue. The Midwest accounting market is getting materially more concentrated.
