What’s Being Said About Us


What’s Being Said About Us

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, Those Guys, Inc.

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!!!

Ben Luchesse, Owner

As clients of Sales Tax Specialists, Inc. for over a decade, we highly recommend their services. Professional, highly skilled, and extremely knowledgeable, Kai Mickey and his team worked tirelessly on our behalf going above and beyond what was expected. We hold them in the highest esteem and are deeply grateful for their professional services.

Patricia and Andrew Laspino, Sea Elm, Inc.

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 use Kai Mickey and STS in the future.

Mary Phillippsen, Enrolled Agent

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!
