Founded in 1977, The Old Tax House began with little more than a calculator, a few pencils and a sincere desire to provide quality tax and accounting services with exceptional customer service.

With persistence, hard work and the best staff in the business, the company grew to become the largest tax office in O'Fallon. 

We're proud of the company we've become. 40 plus years later, we're still committed to those same ideals.
