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.
