Holly Hoffman, CEO of Sales and Income Tax Advisory Network bio picture.

  Holly has worked with the Wisconsin Department of Revenue and now she is on the side of the business to help them through this. She made this audit less painful and helped ensure we weren’t being taken advantage of. I am thankful that she was on our team and educate us as well as the Wisconsin DOR on the rules and laws. I would recommend anyone to use Holly’s services if you are facing a Sales Tax Audit.
