I searched for this and couldn't find it anywhere, so I'll start a new post. Can someone explain when I need to collect sales tax from customers? My mom is making some doggie clothes and beds that I will sell for her on ebay and eventually my own website. Do I have to collect sales tax for these items? Do I collect it from everyone or only people in my state? I don't have a tax ID number yet, do I have to get one? I'm so confused!
