(a) Election as to real property income. A foreign corporation which during the taxable year derives any income from real property which is located in the United States, or derives income from any interest in any such real property, may elect, pursuant to section 882(d) and § 1.871-10, to treat all such income as income which is effectively connected for the taxable year with the conduct of a trade or business in the United States by that corporation. The election may be made whether or not the foreign corporation is engaged in trade or business in the United States during the taxable year for which the election is made or whether or not the corporation has income from real property which for the taxable year is effectively connected with the conduct of a trade or business in the United States, but it may be made only with respect to income from sources within the United States which, without regard to section 882(d) and § 1.871-10, is not effectively connected for the taxable year with the conduct of a trade or business in the United States by that corporation. The income to which the election applies shall be determined as provided in paragraph (b) of § 1.871-10 and shall be subject to tax in the manner, and subject to the same conditions, provided by section 882(a)(1) and paragraph (b)(2) of § 1.882-1. Section 871(d) (2) and (3) and the provisions of § 1.871-10 thereunder shall apply in respect of an election under section 882(d) in the same manner and to the same extent as they apply in respect of elections under section 871(d).

(b) Interest on U.S. obligations received by banks organized in possessions. Interest received from sources within the United States during the taxable year on obligations of the United States by a foreign corporation created or organized in, or under the law of, a possession of the United States and carrying on the banking business in a possession of the United States during the taxable year shall be treated, pursuant to section 882(e) and this paragraph, as income which is effectively connected for the taxable year with the conduct of a trade or business in the United States by that corporation. This paragraph applies whether or not the foreign corporation is engaged in trade or business in the United States at any time during the taxable year but only with respect to income which, without regard to this paragraph, is not effectively connected for the taxable year with the conduct of a trade or business in the United States by that corporation. Any interest to which this paragraph applies shall be subject to tax in the manner, and subject to the same conditions, provided by section 882(a)(1) and paragraph (b)(2) of § 1.882-1. To the extent that deductions are connected with interest to which this paragraph applies, they shall be treated for purposes of section 882(c)(1) and the regulations thereunder as connected with income which is effectively connected for the taxable year with the conduct of a trade or business in the United States by the foreign corporation. An election by the taxpayer is not required in respect of the income to which this paragraph applies. For purposes of this paragraph the term “possession of the United States” includes Guam, the Midway Islands, the Panama Canal Zone, the Commonwealth of Puerto Rico, American Samoa, the Virgin Islands, and Wake Island.

(c) Treatment of income. Any income in respect of which an election described in paragraph (a) of this section is in effect, and any interest to which paragraph (b) of this section applies, shall be treated, for purposes of paragraph (b)(2) of § 1.882-1 and paragraph (a) of § 1.1441-4, as income which is effectively connected for the taxable year with the conduct of a trade or business in the United States by the foreign corporation. A foreign corporation shall not be treated as being engaged in trade or business in the United States merely by reason of having such income for the taxable year.

(d) Effective date. This section applies for taxable years beginning after December 31, 1966. There are no corresponding rules in this part for taxable years beginning before January 1, 1967.
