What’s Being Said About Us

I have a client that seems to be a favorite target of the SBOE. After the first disaster of an audit, when the next time hit us, we hired Kai Mickey to help us get the resolution that the client wanted and deserved. We worked directly with Kai to prepare the work papers for Kai to review and adjust to get a great and deserved result. I am thrilled as is my client. He is so knowledgeable in this arena it makes my job easier. We will continue to Kai Mickey and STS in the future.

Mary Philippsen, Enrolled Agent

STS provided excellent guidance for Those Guys, Inc. (“TGI”) throughout the appeals process with the CA Board of Equalization. STS diligently worked on behalf of TGI to obtain a successful and satisfactory outcome. Most importantly, Kai Mickey is the consummate professional with an incredible skill set to navigate, work with and understand the BOE and their processes. Thank you!

Derek Harding, Vice President,, Those Guys, Inc.

When tax attorneys had all but given up on our case, we were very fortunate to meet Kai at Sales Tax Specialists, via the internet. He took on our case and treated as if it was his own financial future on the line. With his professional knowledge and experience with dealing directly with the State Board, he was able to reduce our liability to zero! Thank you for giving us our life back!

Fred Van Rooyen, Individual

In 40+ years and multiple business dealings with the BOE finding Kai was a blessing. He took a bad looking situation and through sheer determination got us to where we could handle the outcome of the last audit we went through. In any future BOE audits Kai will be in our corner for sure. Thank you!!!
