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. — Colin Hurren, CFO, Magic Hour

The customer service provided by the Tax Rex team has been exceptional. They helped us file historic tax returns as well as ongoing returns to ensure tax compliance. They are very knowledgeable and answer emails promptly. They took the stress out of the experience of registering and paying our sales and use taxes. I highly recommend this App

Great customer service. Really happy with the app so far.

Excellent customer service and on top filings for the last 3 years we used them.

Tax Rex is nothing short of amazing. What I thought would be the most tedious aspect of our business was made seamless by the team at Tax Rex. Really top notch!
