Our Story

In January 2006, David Gross had the crazy idea that an affordable, expert sales tax specialty firm was something that every business could benefit from.

Starting with just one client, one paycheck, and a whole lot of experience and knowledge in the sales and use tax field, Sales Tax Solutions quickly grew to a firm servicing small and large businesses alike, throughout the US and Canada.

STS was born from the idea that sales tax consulting services should be available and affordable to all companies, not just big business. We assist in our clients’ success by helping them become sales tax compliant, and protecting them from government bureaucracy.

Strong companies help strengthen the economy,
protect the jobs of our neighbors, and strengthen our country.

Our Core Values 

God Family Country Honor Virtue 

We have been asked many times why integrity is not in our core values. Integrity is a good word and is used with less and less meaning these days. Honor on the other hand is a word not used too often. Honor encompasses the meaning of integrity but means much more. Honor includes honesty, truth, good character, and respect. The main difference between Honor and integrity is integrity is something you develop, honor is something you have. One can not develop integrity if they do not have honor.
