26 CFR § 1.78-1 - Gross up for deemed paid foreign tax credit.
(a) Taxes deemed paid by certain domestic corporations treated as a dividend. If a domestic corporation chooses to have the benefits of the foreign tax credit under section 901 for any taxable year, an amount that is equal to the U.S. dollar amount of foreign income taxes deemed to be paid by the corporation for the year under section 960 (in the case of section 960(d), determined without regard to the phrase “80 percent of” in section 960(d)(1)) is, to the extent provided by this section, treated as a dividend (a section 78 dividend) received by the domestic corporation from the foreign corporation. A section 78 dividend is treated as a dividend for all purposes of the Code, except that it is not treated as a dividend for purposes of section 245 or 245A, and does not increase the earnings and profits of the domestic corporation or decrease the earnings and profits of the foreign corporation. Any reduction under section 907(a) of the foreign income taxes deemed paid with respect to combined foreign oil and gas income does not affect the amount treated as a section 78 dividend. See § 1.907(a)-1(e)(3). Similarly, any reduction under section 901(e) of the foreign income taxes deemed paid with respect to foreign mineral income does not affect the amount treated as a section 78 dividend. See § 1.901-3(a)(2)(i), (b)(2)(i)(b), and (d) Example 8. Any reduction under section 6038(c)(1)(B) in the foreign taxes paid or accrued by a foreign corporation is taken into account in determining foreign taxes deemed paid and the amount treated as a section 78 dividend. See, for example, § 1.6038-2(k)(5) Example 1. To the extent provided in the Code, section 78 does not apply to any tax not allowed as a credit. See, for example, sections 901(j)(3), 901(k)(7), 901(l)(4), 901(m)(6), and 908(b). For rules on determining the source of a section 78 dividend in computing the limitation on the foreign tax credit under section 904, see §§ 1.861-3(a)(3), 1.862-1(a)(1)(ii), and 1.904-5(m)(6). For rules on assigning a section 78 dividend to a separate category, see § 1.904-4.
(b) Date on which section 78 dividend is received. A section 78 dividend is considered received by a domestic corporation on the date on which -
(1) The corporation includes in gross income under section 951(a)(1)(A) the amounts by reason of which there are deemed paid under section 960(a) the foreign income taxes that give rise to that section 78 dividend, notwithstanding that the foreign income taxes may be carried back or carried over to another taxable year and deemed to be paid or accrued in such other taxable year under section 904(c); or
(2) The corporation includes in gross income under section 951A(a) the amounts by reason of which there are deemed paid under section 960(d) the foreign income taxes that give rise to that section 78 dividend.
(c) Applicability date. This section applies to taxable years of foreign corporations that begin after December 31, 2017, and to taxable years of United States shareholders in which or with which such taxable years of foreign corporations end. The second sentence of paragraph (a) of this section also applies to section 78 dividends that are received after December 31, 2017, by reason of taxes deemed paid under section 960(a) with respect to a taxable year of a foreign corporation beginning before January 1, 2018.
