Capital gains
(i) Capital gains(1) Taxpayers other than corporations. Section 57(a)(9)(A) provides that, in the case of a taxpayer other than a corporation, there is to be included as an item of tax preference one-half of the amount by which the taxpayer's net long-term capital gain for the taxable year exceeds the taxpayer's net short-term capital loss for the taxable year. For this purpose, for taxable years beginning after December 31, 1971, the taxpayer's net long-term capital gain does not include an amount equal to the deduction allowable under section 163 (relating to interest expense) by reason of subsection (d)(1)(C) of that section, and the excess described in the preceding sentence is reduced by an amount equal to the reduction of disallowed interest expense by reason of section 163(d)(2)(B). Furthermore, the net long-term capital gain of an estate or trust does not include capital gains described in section 642(c)(4). Included in the computation of the taxpayer's capital gains item of tax preference are amounts reportable by the taxpayer as distributive shares of gain or loss from partnerships, estates or trusts, electing small business corporations, common trust funds, etc. See section 58 and the regulations thereunder with respect to the above entities.
