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 handles all our USA recording, filing, and remittence. This has saved us a lot of time and has allowed us to focus on more strategic tasks. The team is very responsive when we need to resolve issues or ask questions. We appreciate the Tax Rex partnership very much!

We have been using Tax Rex for one of our stores for over a year. The setup was straightforward, and the support team guided us when we needed help. Being able to exclude marketplace orders is a big plus for us. We recently added the app to our second store, and the integration was super easy. The support team usually replies within a day or two with helpful answers. Overall, it’s been a really good experience so far.

TaxRex has been great to work with. There is no comparison between them and Avalara who was a diaster for us.

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!
