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 help...
— Magic Hour
Quick and easy to install, on-time filing and process was accurately processed and confirmed by state for sales tax filing. Very pleased to find this app to add tax services to small store.

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
— MOZA Racing US
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!
— RYDIR
Great app. The customer service is outstanding also!
— Sierra Yarn
Unprofessional, does not reply to emails, support is nonexistent and they gave us wrong credentials yet can't communicate to fix the issue they created. Do not recommend.
— AMEKANA
Essentially useless. I installed it to file my 2024 sales tax, but it did nothing, leading to a late filing and a penalty. It probably shouldn't advertise automatic filing if it can't deliver.
— Landz.us
10 out of 10 recommend!
— Crave
Taxrex has been a great service. Top notch customer service. Very responsive.
— Aleavia
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
— Dr. Steven Greer - Official Store
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!
— MotoTote
Very responsive team and easy to work with. This app has helped manage and simplify our monthly sales tax requirements immensely.
— Wildfire Lifts
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...
