Do I need to charge sales tax on online orders? I've been running an ecommerce store for a while now and the whole sales tax situation is starting to confuse me. I mean, I've read the articles, talked to a few people, but the rules seem to be very different. Some say it depends on where my business is located, others say it depends on where the client is located. And then there are these thresholds - if you sell more than a certain amount in any state, do you have to collect tax there? Sounds like a bureaucratic maze. I want to do everything legally and ethically, but this is seriously overwhelming. How can I even begin to solve this problem?
