Want to discuss a specific auction running right now on eBay. If you think you've discovered a crazy auction or a scam in the making let's discuss it here.
I plan to open a store and I will run a business at eBay. I wonder if I need to calculate tax and report it in 1040? If not reported in 1040, IRS will catch me later? If I calculate tax, just need to calculate tax sold items in my state, or every items I sold?
