.01 Private Business Use .

(1) Under § 103(a) of the 1986 Code, gross income does not include interest on any state or local bond. Under § 103(b)(1) of the 1986 Code, however, § 103(a) of the 1986 Code does not apply to a private activity bond, unless it is a qualified bond under § 141(e) of the 1986 Code. Section 141(a)(1) of the 1986 Code defines ‘‘private activity bond’’ as any bond issued as part of an issue that meets both the private business use and the private security or payment tests. Under

§ 141(b)(1) of the 1986 Code, an issue generally meets the private business use test if more than 10 percent of the proceeds of the issue are to be used for any private business use. Under § 141(b)(6)(A) of the 1986 Code, private business use means direct or indirect use in a trade or business carried on by any person other than a governmental unit. Section 145(a) of the 1986 Code also applies the private business use test of § 141(b)(1) of the 1986 Code, with certain modifications.

(2) Corresponding provisions of the Internal Revenue Code of 1954 set forth the requirements for the exclusion from gross income of the interest on state or local bonds. For purposes of this revenue procedure, any reference to a 1986 Code provision includes a reference to the corresponding provision, if any, under the 1954 Code.

.02 Section 1.141–3(b)(6)(i) of the Income Tax Regulations provides, in general, that an agreement by a nongovernmental person to sponsor research performed by a governmental person may result in private business use of the property used for the research, based on all of the facts and circumstances.

.03 Section 1.141–3(b)(6)(ii) provides in general that a research agreement with respect to financed property results in private business use of that property if the sponsor is treated as the lessee or owner of financed property for federal income tax purposes.

.04 Section 1.145–2(a) provides generally that §§ 1.141–0 through 1.141–15 apply to § 145(a) of the 1986 Code.

.05 Section 1.145–2(b)(1) provides that, in applying §§ 1.141–0 through 1.141–15 to § 145(a) of the 1986 Code, references to governmental persons include section 501(c)(3) organizations with respect to their activities that do not constitute unrelated trades or businesses under § 513(a) of the 1986 Code.
