§951A Net Cfc Tested Income Included in Gross Income of United States Shareholders

Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter N— Tax Based on Income From Sources Within or Without the United States › Part III— INCOME FROM SOURCES WITHOUT THE UNITED STATES › Subpart F— Controlled Foreign Corporations › § 951A

Last updated Apr 5, 2026|Official source

Summary

Requires each U.S. shareholder of a controlled foreign corporation (CFC) to include that shareholder’s net CFC tested income in their gross income for the year. Net CFC tested income is the positive amount, if any, after subtracting the shareholder’s pro rata share of tested losses from the shareholder’s pro rata share of tested income from all CFCs they own. Tested income for a CFC is its gross income, after leaving out certain specific categories (for example, subpart F items, some related‑party dividends, and foreign oil and gas income), minus the deductions tied to that income. Tested loss is the reverse when deductions exceed that gross income. Pro rata shares are figured the same way as for subpart F under section 951(a)(2) and are counted in the shareholder’s taxable year as under section 951(a)(3). A person is a U.S. shareholder only if they own stock in the foreign corporation on any day in the year. A foreign corporation is a CFC if it is a CFC at any time in the year. The included net CFC tested income is treated the same as amounts included under section 951(a)(1)(A) for the listed code sections (168(h)(2)(B), 535(b)(10), 851(b), 904(h), 959, 961, 962, 993(a)(1)(E), 996(f)(1), 1248(b)(1), 1248(d)(1), 6501(e)(1)(C), 6654(d)(2)(D), and 6655(e)(4)). The Treasury will make rules for other cases that need CFC‑level determinations. If a CFC has no tested income, none of the net amount is treated as from that CFC; if it has tested income, the part treated as from that CFC equals the shareholder’s pro rata tested income from that CFC divided by the total tested income used to compute the net amount.
