(iii) Special circumstances. In determining the expected marginal tax rates of the lessor and lessee, net operating loss and credit carryovers and any other attributes or special circumstances reasonably expected to affect the Federal income tax liability of the taxpayer (including the alternative minimum tax) are taken into account. For example, in the case of a partnership or S corporation, the amount of rental income or deduction that would be allocable to the partners or shareholders, respectively, is taken into account.
26 CFR § 1.467-3
General rule. Under 1.467-1(d)(2)(i), constant rental accrual (as described under paragraph (d) of this section) must be used to determine the fixed rent for each rental period in the lease term if the section 467 rental agreement is a disqualified leaseback or long-term agreement within the meaning of paragraph (b) of this section. Constant rental accrual may not be used in the absence of a determination by the Commissioner, pursuant to paragraph (b)(1)(ii) of this section, that the rental agreement is disqualified. Such determination may be made either on a case-by-case basis or in regulations or other guidance published by the Commissioner (see 601.601(d)(2) of this chapter) providing that a certain type or class of leaseback or long-term agreement will be treated as disqualified and subject to constant rental accrual.
