Sale of personal property not for a profit - how would one prove this income was not TAXABLE? example - we sold items that we have owned for decades this year because one of us has been out of work. We have no proof of what we paid for them back then. Would a paypal account printout suffice for deducting the cost of shipping in the difference between what was reported on the 1099-K? That's what the bulk of this income was, shipping.
