As far as business goes I am unsure of your local laws. But I do know here that if you make any profit 3 out of 5 years doing your hobby, you will be considered a business and held to that standard. If you are not profitable in that same time frame, you can remain hobby status.
You are supposed to report the sales on your taxes. It is taxable income. That's why I got my business license and went right for it. We get to write off all our herp expenses too. As a hobby you can write things off as well (keep your receipts), but it would just bring you to a total of 0 if you spent more than you earned. As a business, money I have spent more than what I have earned becomes a part of my return. Just food for thought![]()
