5 Star Customer Reviews

5 years ago I found STL tax after dealing with another tax preparer that refused to return calls. STL Tax is everything the other place was not. Jim & everyone I have come into contact with are friendly, courteous, professional, knowledgeable. The rates are reasonable, and they walk you through every step, providing as much guidance as you require. They promptly return emails and/or phone calls, which is much appreciated.
