§ 453B.
(a)
General rule
If an installment obligation is satisfied at other than its face value or distributed, transmitted, sold, or otherwise disposed of, gain or loss shall result to the extent of the difference between the basis of the obligation and—
(1)
the amount realized, in the case of satisfaction at other than face value or a sale or exchange, or
(2)
the fair market value of the obligation at the time of distribution, transmission, or disposition, in the case of the distribution, transmission, or disposition otherwise than by sale or exchange.
any gain or loss so resulting shall be considered as resulting from the sale or exchange of the property in respect of which the installment obligation was received.
(f)
Obligation becomes unenforceable
For purposes of this section, if any installment obligation is canceled or otherwise becomes unenforceable—
(1)
the obligation shall be treated as if it were disposed of in a transaction other than a sale or exchange, and
(2)
if the obligor and obligee are related persons (within the meaning of section 453(f)(1)), the fair market value of the obligation shall be treated as not less than its face amount.
(g)
Transfers between spouses or incident to divorce
In the case of any transfer described in subsection (a) of section 1041 (other than a transfer in trust)—
(1)
subsection (a) of this section shall not apply, and
(2)
the same tax treatment with respect to the transferred installment obligation shall apply to the transferee as would have applied to the transferor.
(h)
Certain liquidating distributions by S corporations
If—
(1)
an installment obligation is distributed by an S corporation in a complete liquidation, and
(2)
receipt of the obligation is not treated as payment for the stock by reason of section 453(h)(1),
then, except for purposes of any tax imposed by subchapter S, no gain or loss with respect to the distribution of the obligation shall be recognized by the distributing corporation. Under regulations prescribed by the Secretary, the character of the gain or loss to the shareholder shall be determined in accordance with the principles of section 1366(b).
