As the CFO of Magic Hour, I cannot say enough good things about Tax Rex and their team. We initially engaged them to help us manage our Shopify sales tax compliance, but they quickly became a trusted partner in resolving a complex and long-standing sales tax issue with the California tax authorities.
From day one, their team was incredibly responsive, knowledgeable, and genuinely committed to helping us find solutions. No question was too small, and every interaction was professional, timely, and helpful. They guided us through a challenging situation with patience and expertise, giving us confidence that we were finally on the right track.
The Tax Rex platform itself is easy to use and has simplified our multi-state sales tax reporting and filing process. Equally important, the people behind the software are exceptional. In an industry where customer support can often be frustrating, Tax Rex has consistently exceeded our expectations.
I highly recommend Tax Rex to any Shopify merchant looking for a reliable sales tax solution backed by outstanding customer service and real expertise.
