§ 1.1374-8. Section 1374(d)(8) transactions.

(i) X is a C corporation that elected to become an S corporation effective January 1, 1986 (before section 1374 was amended in the Tax Reform Act of 1986). X has a net operating loss carryforward of $20,000 arising in 1985 when X was a C corporation. On January 1, 1996, Y (an unrelated C corporation) merges into X in a transaction to which section 368(a)(1)(A) applies. Y has no loss carryforwards, credits, or credit carryforwards. The assets X acquired from Y are subject to tax under section 1374 and have a net unrealized built-in gain of $150,000.

(ii) In 1996, X has a pre-limitation amount of $50,000 on dispositions of assets acquired from Y and a taxable income limitation of $100,000 (because only one group of assets is subject to section 1374, there is no allocation of the taxable income limitation). As a result, X has a net recognized built-in gain on those assets of $50,000. X's $20,000 net operating loss carryforward may not be used as a deduction against its $50,000 net recognized built-in gain on the assets X acquired from Y. Therefore, X has a section 1374 tax of $17,500 ($50,000 × .35 = $17,500, assuming a 35 percent tax rate) for its 1996 taxable year.

(i) Y is a C corporation that elects to become an S corporation effective January 1, 1996. The assets Y holds when it becomes an S corporation have a net unrealized built-in gain of $5,000. Y has no loss carryforwards, credits, or credit carryforwards. On January 1, 1997, Z (an unrelated C corporation) merges into Y in a transaction to which section 368(a)(1)(A) applies. Z has no loss carryforwards, credits, or credit carryforwards. The assets Y acquired from Z are subject to tax under section 1374 and have a net unrealized built-in gain of $80,000.

(ii) In 1997, Y has a pre-limitation amount on the assets it held when it became an S corporation of $15,000, a pre-limitation amount on the assets Y acquired from Z of $15,000, and a taxable income limitation of $10,000. However, because the assets Y held on becoming an S corporation have a net unrealized built-in gain of $5,000, its net recognized built-in gain on those assets is limited to $5,000 before taking into account the taxable income limitation. Y's taxable income limitation of $10,000 is allocated between the assets Y held on becoming an S corporation and the assets Y acquired from Z for purposes of determining the net recognized built-in gain from each pool of assets. Thus, Y's net recognized built-in gain on the assets Y held on becoming an S corporation is $2,500 [$10,000 × ($5,000/$20,000) = $2,500]. Y's net recognized built-in gain on the assets Y acquired from Z is $7,500 [$10,000 × ($15,000/$20,000) = $7,500]. Therefore, Y has a section 1374 tax of $3,500 [($2,500 + $7,500) × .35 = $3,500, assuming a 35 percent tax rate] for its 1997 taxable year.
