KSM Named Among “Best of the Best” CPA Firms for 24th Year

Summary: For the 24^th time, KSM (Katz, Sapper & Miller) has earned recognition from INSIDE Public Accounting (IPA) as a “Best of the Best” accounting firm.

INDIANAPOLIS – KSM (Katz, Sapper & Miller), a leading advisory, tax, and audit firm, has been named one of the “Best of the Best” accounting firms for 2025 by INSIDE Public Accounting (IPA). This marks the 24^th consecutive year the firm has been recognized on this prestigious list.

The Best of the Best list comprises 75 CPA firms – including 60 firms with over $10 million in net revenue, 10 smaller firms, and five Canadian firms. KSM is the only Indiana-based public accounting firm to earn the honor for 2025.

KSM has operated as an employee-owned firm since 2001. The firm’s growth has been fueled by successful client relationships and expanded service offerings, as well as strategic acquisitions that bring together top-tier talent and broaden KSM’s geographic reach. For 2024, the year IPA evaluated, this included the successful integration of Shanholt Glassman Klein Kramer & Co. (SGKK) in New York City and Cassady Schiller in Cincinnati. This combination of employee ownership and strategic growth continues to strengthen KSM’s ability to deliver innovative solutions and exceptional client service.

“We are honored to once again be recognized among the top performing CPA firms. What makes KSM truly unique is our employee ownership model, ensuring every one of our employee owners has a stake in our collective success,” said Tim Cook, KSM CEO and president. “Our ownership mindset drives collaboration, accountability, and innovation in ways that directly benefit our clients and our firm’s future. As we continue to grow, we remain committed to building a sustainable, thriving firm for the next generation of employee-owners.”

To determine the Best of the Best, IPA evaluates more than 600 participating firms using a rigorous scoring system based on 35-plus metrics. These metrics cover a range of factors including net revenue growth, governance, long-range planning, professional development, compensation, and operational efficiency.
