AMTI is defined as the taxable income of a taxpayer determined with adjustments provided in sections 56 and 58, and increased by items of tax preference described in section 57. Sec. 55(b)(2); Merlo v. Commissioner, 126 T.C. 205, 209 (2006), affd. F.3d (5th Cir., July 17, 2007); Allen v. Commissioner, supra at 5. Pertinent to this case, for purposes of computing a taxpayer’s AMTI, section 56(b)(3) provides that section 421 shall not apply to the transfer of stock acquired pursuant to the exercise of an ISO. Therefore, the spread between the exercise price and the fair market value of the stock on the date of exercise is treated as an item of adjustment and is included in AMTI.5 Sec 83(a); Tanner v. Commissioner, 117 T.C. 237, 242 (2001), affd. 65 Fed. Appx. 508 (5th Cir. 2003); sec. 1.83-7(a), Income Tax Regs. As a result of these differing treatments, a taxpayer subject to the AMT has two different bases in the shares of stock he received upon exercising the ISO: a regular basis and an adjusted AMT basis. Merlo v. Commissioner, supra at 209; Spitz v. Commissioner, T.C. Memo. 2006-168. The taxpayer’s regular basis is the exercise price. See sec. 1012. The adjusted AMT 5If the taxpayer’s rights in the shares are subject to a substantial risk of forfeiture or not transferable, income is not recognized at the time of exercise.
