Following the 2017 Tax Act, the US tax costs to a corporate US shareholder that sells stock in a controlled foreign corporation (CFC) are significantly reduced. Beginning in 2018, the amount of gain will be generally less than in prior years and most or all such gain will frequently not be subject to any US federal income taxation.

The amount of gain recognized in a sale of course is the difference between the amount realized and the selling shareholder’s adjusted tax basis in the stock of the CFC. The initial basis in the stock of a CFC is increased by the amount of earnings of the CFC and its subsidiaries that was included in the gross income of the domestic corporation under Subpart F (i.e., previously taxed earnings). The increase in basis can be significant as a result of the transition tax Subpart F inclusion of post-1986 earnings of CFCs and the expansion of Subpart F inclusions for global intangible low-taxed income (GILTI).

The gain recognized by a domestic corporation upon the sale of stock in a CFC generally is capital gain subject to a 21 percent tax rate. Section 1248, however, recharacterizes as a deemed dividend all or a portion of the gain. The amount of gain recharacterized generally equals the amount of non-previously taxed earnings of the CFC and its foreign subsidiaries. Provided the domestic corporate shareholder held the CFC stock for at least one year, the amount of the gain recharacterized as a dividend generally is eligible for a 100 percent dividends received deduction under section 245A.
