Our History

Katz, Sapper & Miller began as a small, dedicated CPA firm in Indianapolis and grew by helping our clients tend and advance their closely held, family-owned businesses.

A Look Back Through the Years

For decades, KSM was known as Indiana’s go-to tax and audit firm – a reputation we continue to hold to this day.

But our reputation and reach have grown. Today, we have multiple offices and serve an impressive roster of clients across the nation who count on us to be their trusted advisors.
