Nonbusiness Bad Debts -

Report a nonbusiness bad debt as a short-term capital loss on Form 8949, Sales and Other Dispositions of Capital Assets (PDF), Part 1, line 1. Enter the name of the debtor and "bad debt statement attached" in column (a). Enter your basis in the bad debt in column (e) and enter zero in column (d). Use a separate line for each bad debt. It's subject to the capital loss limitations. A nonbusiness bad debt deduction requires a separate detailed statement attached to your return. The statement must contain: a description of the debt, including the amount and the date it became due; the name of the debtor, and any business or family relationship between you and the debtor; the efforts you made to collect the debt; and why you decided the debt was worthless.
