Example. US is a U.S. citizen. US owns 100% of the stock of DC, a domestic corporation. DC owns a 60% direct interest in FPS, a foreign partnership. DC and US are the only U.S. persons that own interests directly or constructively in FPS. DC owns directly a greater than 50% interest in FPS. US constructively owns DC's interest pursuant to sections 6038(e)(3) and 267(c)(1). Therefore, both DC and US are controlling fifty-percent partners. US qualifies for both the exception in paragraph (c)(1) of this section (multiple controlling fifty-percent partners) and the exception in paragraph (c)(2) of this section (constructive owner exception). US may only utilize the paragraph (c)(1) exception to avoid its filing obligation. Accordingly, DC may file a single Form 8865 on behalf of US and itself. However, that form must contain all the information that would have been submitted had DC and US each submitted a separate Form 8865.
