✔ 最佳答案
"but made less than 100 dollars on it"
You need to report both parts of the transaction. This gives the NET income/loss.
You did not say how much your 1099 is. If you don't report it, the government only sees one side, the preceeds (how much you sold it for) and will tax you on that.
By reporting both the amount you paid (your basis) and the amout you sold it for (proceeds) you can show whether it was a gain (sold for more than you paid) or a loss (sold for less than you paid)..
