Code of Federal Regulations Title 26. Internal Revenue § 26.1.57–0 Scope

For purposes of the minimum tax for tax preferences (subtitle A, chapter I, part VI), the items of tax preference are:

Accelerated depreciation on section 1245 property subject to a net lease and excess investment interest are not items of tax preference in the case of a corporation, other than a personal holding company (as defined in section 542) and an electing small business corporation (as defined in section 1371(b)). In addition, excess investment interest is an item of tax preference only for taxable years beginning before January 1, 1972. Rules for the determination of the items of tax preference are contained in §§ 1.57–1 through 1.57–5. Generally, in the case of a nonresident alien or foreign corporation, the application of §§ 1.57–1 through 1.57–5 will be limited to cases in which the taxpayer has income effectively connected with the conduct of a trade or business within the United States. Special rules for the treatment of items of tax preference in the case of certain entities and the treatment of items of tax preference relating to income from sources outside the United States are provided in section 58 and in §§ 1.58–1 through 1.58–8.
