Tax Rex ‑ Sales Tax Automation

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 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!!

I cannot recommend Tax Rex enough. Efficient, prompt, affordable and quite easy to use (even for artists).
Tax Rex has simplified our bookkeeping and given us peace of mind. Highly recommend.

I honestly cannot thank the Tax Rex support team enough. I have full confidence in them completing my monthly tax filing and yearly TPT license and do not even have to think about it. I know it is completed and filed correctly. With all of the things day to day running a business, this helps tremendously as I would probably be late filing each time.

Super helpful and compitent. Great communicators, albiet over email, but it's worked out well. We had a bit of a mess to clean up, and they managed it very very well, and provided great details to help us manage the payback of backtaxes.

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!

I have been using Tax Rex for a couple of years, and I am very happy with the service.

I sort of stumbled through setting it up, but they were very helpful, and they have been very responsive every time I have a question or need to speak to them about my taxes.

Really wonderful customer service. They jump on any issues I have with any state and are super helpful. No way could I deal with all the various sales tax state rules on my own. Love this app and the team behind 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.
