A year ago I created a RedBubble account had no clue what I was doing or getting into just wanted to see what would happen....and nothing did, I didn't promote it or push it but somehow people are now finding it and I sell a few shirts each month. So now I am wondering how do I claim and pay taxes on this income? I am a freelance Graphic Designer still working on building a real business. Thanks for any advise you can offer.
