(a) General rule
(1) Wholly worthless debts
There shall be allowed as a deduction any debt which becomes worthless within the taxable year. When satisfied that a debt is recoverable only in part, the Secretary may allow such debt, in an amount not in excess of the part charged off within the taxable year, as a deduction. For purposes of subsection (a), the basis for determining the amount of the deduction for any bad debt shall be the adjusted basis provided in section 1011 for determining the loss from the sale or other disposition of property. [(c) Repealed. Pub.

For purposes of paragraph (1), the term "nonbusiness debt" means a debt other than— (A) a debt created or acquired (as the case may be) in connection with a trade or business of the taxpayer; or (B) a debt the loss from the worthlessness of which is incurred in the taxpayer's trade or business. This section shall not apply to a debt which is evidenced by a security as defined in section 165(g)(2)(C).
