[Code of Federal Regulations] [Title 26, Volume 2] [Revised as of April 1, 2004] From the U.S. Government Printing Office via GPO Access [CITE: 26CFR1.166-5] [Page 918-919] TITLE 26--INTERNAL REVENUE CHAPTER I--INTERNAL REVENUE SERVICE, DEPARTMENT OF THE TREASURY (CONTINUED) PART 1_INCOME TAXES--Table of Contents Sec. 1.166-5 Nonbusiness debts. (a) Allowance of deduction as capital loss. (1) The loss resulting from any nonbusiness debt's becoming partially or wholly worthless within the taxable year shall not be allowed as a deduction under either section 166(a) or section 166(c) in determining the taxable income of a taxpayer other than a corporation. See section 166(d)(1)(A). (2) If, in the case of a taxpayer other than a corporation, a nonbusiness debt becomes wholly worthless within the taxable year, the loss resulting therefrom shall be treated as a loss from the sale or exchange, during the taxable year, of a capital asset held for not more than 1 year (6 months for taxable years beginning before 1977; 9 months for taxable years beginning in 1977). Such a loss is subject to the limitations provided in section 1211, relating to the limitation on capital losses, and section 1212, relating to the capital loss carryover, and in the regulations under those sections. A loss on a nonbusiness debt shall be treated as sustained only if and when the debt has become totally worthless, and no deduction shall be allowed for a nonbusiness debt which is recoverable in part during the taxable year. (b) Nonbusiness debt defined. For purposes of section 166 and this section, a nonbusiness debt is any debt other than-- (1) A debt which is created, or acquired, in the course of a trade or business of the taxpayer, determined without regard to the relationship of the debt to a trade or business of the taxpayer at the time when the debt becomes worthless; or (2) A debt the loss from the worthlessness of which is incurred in the taxpayer's trade or business. The question whether a debt is a nonbusiness debt is a question of fact in each particular case. The determination of whether the loss on a debt's becoming worthless has been incurred in a trade or business of the taxpayer shall, for this purpose, be made in substantially the same manner for determining whether a loss has been incurred in a trade or business for purposes of section 165(c)(1). For purposes of subparagraph (2) of this paragraph, the character of the debt is to be determined by the relation which the loss resulting from the debt's becoming worthless bears to the trade or business of the taxpayer. If that relation is a proximate one in the conduct of the trade or business in which the taxpayer [[Page 919]] is engaged at the time the debt becomes worthless, the debt comes within the exception provided by that subparagraph. The use to which the borrowed funds are put by the debtor is of no consequence in making a determination under this paragraph. For purposes of section 166 and this section, a nonbusiness debt does not include a debt described in section 165(g)(2)(C). See Sec. 1.165-5, relating to losses on worthless securities. (c) Guaranty of obligations. For provisions treating a loss sustained by a guarantor of obligations as a loss resulting from the worthlessness of a debt, see Sec. Sec. 1.166-8 and 1.166-9. (d) Examples. The application of this section may be illustrated by the following examples involving a case where A, an individual who is engaged in the grocery business and who makes his return on the basis of the calendar year, extends credit to B in 1955 on an open account: Example (1). In 1956 A sells the business but retains the claim against B. The claim becomes worthless in A's hands in 1957. A's loss is not controlled by the nonbusiness debt provisions, since the original consideration has been advanced by A in his trade or business. Example (2). In 1956 A sells the business to C but sells the claim against B to the taxpayer, D. The claim becomes worthless in D's hands in 1957. During 1956 and 1957, D is not engaged in any trade or business. D's loss is controlled by the nonbusiness debt provisions even though the original consideration has been advanced by A in his trade or business, since the debt has not been created or acquired in connection with a trade or business of D and since in 1957 D is not engaged in a trade or business incident to the conduct of which a loss from the worthlessness of such claim is a proximate result. Example (3). In 1956 A dies, leaving the business, including the accounts receivable, to his son, C, the taxpayer. The claim against B becomes worthless in C's hands in 1957. C's loss is not controlled by the nonbusiness debt provisions. While C does not advance any consideration for the claim, or create or acquire it in connection with his trade or business, the loss is sustained as a proximate incident to the conduct of the trade or business in which he is engaged at the time the debt becomes worthless. Example (4). In 1956 A dies, leaving the business to his son, C, but leaving the claim against B to his son, D, the taxpayer. The claim against B becomes worthless in D's hands in 1957. During 1956 and 1957, D is not engaged in any trade or business. D's loss is controlled by the nonbusiness debt provisions even though the original consideration has been advanced by A in his trade or business, since the debt has not been created or acquired in connection with a trade or business of D and since in 1957 D is not engaged in a trade or business incident to the conduct of which a loss from the worthlessness of such claim is a proximate result. Example (5). In 1956 A dies; and, while his executor, C, is carrying on the business, the claim against B becomes worthless in 1957. The loss sustained by A's estate is not controlled by the nonbusiness debt provisions. While C does not advance any consideration for the claim on behalf of the estate, or create or acquire it in connection with a trade or business in which the estate is engaged, the loss is sustained as a proximate incident to the conduct of the trade or business in which the estate is engaged at the time the debt becomes worthless. Example (6). In 1956, A, in liquidating the business, attempts to collect the claim against B but finds that it has become worthless. A's loss is not controlled by the nonbusiness debt provisions, since the original consideration has been advanced by A in his trade or business and since a loss incurred in liquidating a trade or business is a proximate incident to the conduct thereof.
