net capital gain
(2) Notwithstanding subparagraph (1) of this paragraph, in the case of a taxpayer other than a corporation for taxable years beginning before January 1, 1964, the term net capital gain means the excess of (i) the sum of the gains from sales or exchanges of capital assets, plus the taxable income (computed without regard to gains and losses from sales or exchanges of capital assets and without regard to the deductions provided by section 151, relating to personal exemptions, or any deductions in lieu thereof) of the taxpayer or $1,000, whichever is smaller, over (ii) the losses from sales or exchanges of capital assets, which losses include amounts carried to the taxable year by such taxpayer under paragraph (a)(1) of 1.12121. Thus, in the case of estates and trusts for taxable years beginning before January 1, 1964, taxable income for the purposes of this paragraph shall be computed without regard to gains and losses from sales or exchanges of capital assets and without regard to the deductions allowed by section 642(b) to estates and trusts in lieu of personal exemptions. The term net capital gain is not applicable in the case of a taxpayer other than a corporation for taxable years beginning after December 31, 1963, and before January 1, 1970. In the case of a taxpayer whose tax liability is computed under section 3 for taxable years beginning before January 1, 1964, the term taxable income, for purposes of this paragraph, shall be read as adjusted gross income.
