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!

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

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.

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!

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 in determining sales tax obligation with the 'Economic Nexus' laws. The app is very simple to use, have very clear reports for filing and is very inexpensive to use given the amount of time we save in reporting tax across several states.

Given the very limited Shopify Tax for non-Plus stores, this is a must have to streamline the tax back-end and stay in compliance.

Excellent app, excellent value and truly excellent and quick support!!
