We have a recent problem with a tax group we set up last year. It seems that NS changed something in the back end about how this particular tax group works a few weeks ago. A little background info: We are located in NJ, but after the Wayfair Supreme Court case, we now have economic nexus in Illinois due to the volume of sales we do in that state. We could have set up the entire state of Illinois with 'Use State Tax Tables', but since Illinois does NOT want out of state sellers with economic nexus to remit local or county sales tax, we set up a tax group for the state of Illinois to collect ONLY the state tax of 6.25%. We created the tax group with the correct rate and populated the State field with 'Illinois'. This has worked flawlessly until a few weeks ago, when we were finding sales orders shipping to addresses in Illinois set to our default tax code of -Not Taxable- for orders which were subject to Illinois sales tax based on the 'Taxable' field being checked and the 'Tax Item' field being empty on the customer record(s) in question. Has anyone else noticed this potentially HUGE problem in their accounts?
