I'm neither an accountant nor an American, but I thought that e-commerce was a grey area with respect to sales taxes in the US. Most e-commerce companies didn't charge sales tax outside of the state they operated in. During the dotcom days I was assigned to research the implications of interstate transactions, and honestly, all that nexus stuff was dizzying. I only recall hearing periodically (every couple of years) that the ecommerce sales tax moratorium (if you can call it that) had been extended yet again. Is that still the case?
