- 20 - APPENDIX The taxpayer's tentative minimum tax is computed as follows. The taxable income, as it is normally calculated, is recomputed to create a new tax base, the alternative minimum taxable income (AMTI). See sec. 55(b)(2). The normal taxable income is reduced by the adjustments provided for in sections 56 and 58 and increased by the amount of the items of tax preference described in section 57. In petitioner's case, the only applicable adjustment from these sections is the disallowance of the standard deduction and the personal exemption. See sec. 56(b)(1)(E). Petitioner's regular taxable income was $155,599 and was increased by the previously allowed deduction of $5,750 and exemption of $7,926. His AMTI was $169,275. The AMTI is then reduced by the special AMT exemption allowed according to the taxpayer's status. See sec. 55(d). For taxpayers who are unmarried but not widowed, like petitioner, the exemption amount is $33,750. See id. However, the exemption amount is phased out if the AMTI exceeds a certain amount. For unmarried, not widowed, individuals, 25 percent of income exceeding $112,500 is subtracted from the exemption amount. See id. Petitioner's AMTI exceeded $112,500 by $56,775. Twenty-five percent of that is $14,194, so petitioner's $33,750 exemption is reduced to $19,556.Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Next
