So if its a profit or 400, 600 or whatever, isnt that only after you ahve recouped the tank setup costs? So like basically never for most of us. But if your taking in 2g/yr w cards maybe the irs might come after you? But then you just tell them the tank costed you 8g? Its gotta be total cost inlcuding setup not just ongoing right cost right?
If you are receiving income, technically the IRS wants to know about it, as stated above, even a garage sale. Get a scratch off ticket for your birthday and win $1k ..guess what, they are sending that info to the IRS.
