Minimum tax
(2) Minimum tax. The term taxes imposed on the trust attributable to the undistributed capital gain also includes the minimum tax for tax preferences imposed on the trust by section 56 with respect to the undistributed capital gain. The amount of such minimum tax so included bears the same relation to the total amount of minimum tax imposed on the trust by section 56 for the taxable year as one-half the net capital gain (net section 1201 gain for taxable years beginning before January 1, 1977) (as defined in section 1222(11)) from such taxable year bears to the sum of the items of tax preference of the trust for such taxable year which are apportioned to the trust in accordance with 1.58-3(a) (1). (3) Reduction for prior distribution. If in any taxable year a capital gain distribution is made by the trust which results in a throwback to a prior year, the taxes of the prior year imposed on the trust attributable to any remaining undistributed capital gain of the prior year are the taxes prescribed in subparagraph (1) of this paragraph reduced by the taxes of the prior year deemed distributed under section 669 (d) or (e). The provisions of this subparagraph may be illustrated by the following example:
