1.141-3 (a) General rule --

(1) In general.

The private business use test relates to the use of the proceeds of an issue. The 10 percent private business use test of section 141(b)(1) is met if more than 10 percent of the proceeds of an issue is used in a trade or business of a nongovernmental person. For this purpose, the use of financed property is treated as the direct use of proceeds. Any activity carried on by a person other than a natural person is treated as a trade or business. Unless the context or a provision clearly requires otherwise, this section also applies to the private business use test under sections 141(b)(3) (unrelated or disproportionate use), 141(b)(4) ($15 million limitation for certain output facilities), and 141(b)(5) (the coordination with the volume cap where the nonqualified amount exceeds $15 million).

(2) Indirect use.

In determining whether an issue meets the private business use test, it is necessary to look to both the indirect and direct uses of proceeds. For example, a facility is treated as being used for a private business use if it is leased to a nongovernmental person and subleased to a governmental person or if it is leased to a governmental person and then subleased to a nongovernmental person, provided that in each case the nongovernmental person’s use is in a trade or business. Similarly, the issuer‘s use of the proceeds to engage in a series of financing transactions for property to be used by nongovernmental persons in their trades or businesses may cause the private business use test to be met. In addition, proceeds are treated as used in the trade or business of a nongovernmental person if a nongovernmental person, as a result of a single transaction or a series of related transactions, uses property acquired with the proceeds of an issue.

(3) Aggregation of private business use.

The use of proceeds by all nongovernmental persons is aggregated to determine whether the private business use test is met.
