Our bottom line is to make each client feel like they are our only client.” Many of our clients begin with us out of frustration of an environment of unanswered or delayed answers of their phone calls or emails from their consultant “says Steve Sattizahn. “Our industry has gone through a lot of buyouts and merging making large conglomerates. The mid-sized corporations are not receiving their needs as quickly as they need”. RTS combines that attitude with over 30 years of experience and good relations with local jurisdictions. That combination spells success for us and our Clients!

Our clients also come to us because they are tired of the high fees of their larger firms.


Our business model is a senior advisor-focused approach. Staff works for our partners and the partners work for you.  We have assisted tax leaders of some of the largest Corporations in America with indirect tax issues and problem solving.
