Last time I looked, in Australia you could make a few bucks doing something that was classed as a hobby rather than a business. There wasn't a formal dollar value limit. Short answer was that the Tax Office couldn't be bothered with the small stuff, so Aunt Mabel is able to sell her apricot preserves at the local market without getting taxed. Now if you're pulling in $50G a year doing it they'd probably be interested. To answer the original question, I think it's a bit of a gray area. My personal impression is that if you have a full-time job and cut wood on the weekends to sell, it's not a business. If you're working for a wage part-time and cutting wood to sell the rest of the time, then it is. Whether the IRS agrees is another matter, of course.
That's probably not much help to you .
I work a full time 50hr job plus do logging/firewood full time as well. Ends up being 80-100hrs a week or so.
