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.

Incredible customer service. Communicative, detailed, knowledgeable, thoughtful, and responsible associates. Quick response times (typically 1-2 business days). They have made state registration and the filing and payment of our sales taxes a breeze. What once was a headache for us and our clients is a headache no more. Can't recommend them highly enough for the services they provide.

The Tax Rex team has been on top of absolutely every question I have and have rectified any issues I've had very quickly. I use them for several states to autofile and they are always on top of getting everything filed early and efficiently. So happy with our service!

Takes all the worry out of filing away. We've been using this app for over a year now and had no issues. Tech support, on the rare occasion that we have needed it, is quick to resolve any issues. Great investment!

I've been using Tax Rex for over a year now and it has saved me hours of headache trying to reconsolidate all the tax info (especially county tax) for filing each filing period.

This year I decided to file using Tax Rex (instead of just having it report it in Shopify) and they took care of everything, which has been a life + time saver.

Their customer support is also very responsive, making this app a must have for any small busines sowner!

I've been using Tax Rex I believe for 2 or 3 years now. I was skeptical at first b/c of such bad experiences in the past with several other services. So I started out only having them manage one or two states in the beginning, but now they manage the majority of states I do work in and I plan to add more when I expand into other states.

I highly recommend Tax Rex they also do a good job of communicating via email and are prompt to respond.

I switched from Avalara to Tax Rex and OMG what a change! Customer service is way better, they actually respond in a timely fashion and don't sound like robots. Taxes are calculated correctly (unlike Avalara whose calculations were double what they were supposed to be) and they go out of their way to help.

The state comptroller switched us to monthly sales tax filing, and we missed the notification, so we were late with one month’s filing. Tax Rex responded quickly and had everything taken care of in less than 24 hours. Highly recommend!

This app is an absolute must have if you reach nexus in multiple states. Manually dealing with state orgs is such a headache and seriously gave me anxiety in the midst of a busy growing business.

Tax Rex has been a lifesaver. I never have to think about taxes. I just get nifty little reports in my email that all has been handled.

Last week, I received a state notice for an unpaid month right when we reached nexus and before I'd set up autofile. I was heading out of town and didn't have time to dig into it. I sent an email to Tax Rex support and they handled it while I traveled.

Truly a great app and I'm so grateful I don't have to worry about managing taxes anymore.

We've had a great experience using the Tax Rex app for managing our sales tax filings. Their support is responsive, and the filing process in Autofile-enrolled states runs smoothly and on time. Highly recommend this app to any business looking for a reliable sales tax solution on Shopify!

Tax Rex has been absolutely amazing for me! Their pricing is very fair, and their support to register with every state was a HUGE time saver worth every penny! And! This stuff is all SUPER complicated, they have been very responsive via their customer support email, always getting back to me within 24 hours, and have helped me along every step of the way!
