Hey all, I've been lurking for a bit here and finally have a question to post. I plan on doing web design on the side through an offline marketing plan I've put into action. I will be receiving payments either through check or cash only. If I am only predicting net profit of about $4000 for the year, is it necessary to file taxes or can I get away with it? I would be a sole proprietorship, so I'd be paying the personal income tax + the self-employment tax - which is a ridiculous percentage of my profit going straight to the IRS.
