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 application interface is very clean, the features are very practical, the tax team submits data in a timely manner, and customer service responds to emails promptly as well

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!

Great app. The customer service is outstanding also!

10 out of 10 recommend!

Taxrex has been a great service. Top notch customer service. Very responsive.

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

We've been using Tax Rex for at least a year, if I remember correctly. They have executed flawlessly and eliminated all the stress and hassle related to sales tax. Their customer service is prompt, courteous and professional. I highly recommend Tax Rex!

Very responsive team and easy to work with. This app has helped manage and simplify our monthly sales tax requirements immensely.

I don't know why I was trying to do it on my own. We operate in a single state (California) and their tax filings are horrible. Shopify tax was difficult to manually process, and their automated filings worked but wouldn't allow for companies that have to remit monthly tax filings. Tax Rex to the rescue! We are new with them, but communication is great and looks like we are good to go. What was a 1/2 day process trying to sort through reports is now automatic. Thank You!

Tax Rex has been a huge help for our Shopify store. The app itself works exactly as needed, but what really stands out is the customer service. Their team is incredibly patient, responsive, and thorough. Every question we’ve had — even the small, technical ones — has been handled quickly and clearly. They take the time to explain things in a way that actually makes sense, which is rare when dealing with tax-related tools. It’s clear they care about getting it right, not just closing tickets. Highly recommend if you’re looking for a reliable solution backed by a truly supportive team.

Easy to use and great customer service. Taxes are efffin hard and they are making this so easy for my small biz. Love it!

Tax Rex is super helpful with quick responses and guidance to tax-related issues!

This app works as expected. The time saved is worth the cost.
