This document contains temporary regulations that provide guidance regarding the income inclusion rules under section 50(d)(5) of the Internal Revenue Code (Code) that are applicable to a lessee of investment credit property when a lessor of such property elects to treat the lessee as having acquired the property. These temporary regulations also provide rules to coordinate the section 50(a) recapture rules with the section 50(d)(5) income inclusion rules. In addition, these temporary regulations provide rules regarding income inclusion upon a lease termination, lease disposition by a lessee, or disposition of a partner's or S corporation shareholder's entire interest in a lessee partnership or S corporation outside of the recapture period. Accordingly, these regulations will affect lessees of investment credit property when the lessor of such property makes an election to treat the lessee as having acquired the property and an investment credit is determined under section 46 with respect to such lessee. The text of these temporary regulations also serves as the text of the proposed regulations set forth in the Proposed Rules section in this issue of the Federal Register.
