What merchants think

Feedback submitted

Merchants say this is a strong, time‑saving solution for multi‑state sales tax. It simplifies complex monthly or quarterly filings, with many calling it worth every penny. Auto‑file is praised for accurate, on‑time submissions and peace of mind. Reports are clear, flexible, and sometimes more accurate than Shopify’s. Support is frequently described as responsive, proactive, and highly knowledgeable, helping with registrations, notices, and custom reporting.

extremely easy to use, very efficient and has saved me a lot of time. I highly recommend to anyone who has to file with multiple states with multiple counties. Taxrex also provides good reports and excellent support and communication. It is a no-brainer to use their company. I use to do all of my own filings, but they are efficient and economical.

TaxRex has helped remove a very cumbersome task, which is accurately reporting done on time for more than a dozen states. The time savings is well worth the cost. Customer service is responsive too, A+

TaxRex is a straightforward, inexpensive solution to sales tax handling for our small ecommerce business. Highly recommend if you just want compliance and don't need more bells and whistles than necessary.

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.
