About Us

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 preparation and book keeping services with exceptional customer service in a professional, yet relaxed environment.

With persistence, hard work, and the best staff in the business, the company grew to become the largest tax office in O'Fallon, Missouri. Assisting our customers with a high level of personal service is our trademark.

Thirty-five years later, we are still committed to those same ideals and are very proud of the company we have become. What's our secret? You! The dedication and referrals from our clients have made us the company we are today. In honor of our 35th Anniversary, all of us at The Old Tax House would like to say a heartfelt, Thank you, to our clients.
