The general overview of the practice unit includes the following:

General Overview

The Tax Cuts and Jobs Act enacted section 250, which provides for a deduction with respect to Global Intangible Low-Taxed Income (GILTI) and Foreign-Derived Intangible Income (FDII). The deduction is only available to domestic corporations (except that the GILTI deduction is also available to individuals that make a section 962 election).

The section 250 deduction helps neutralise the role that tax considerations play when a domestic corporation chooses the location of intangible income attributable to foreign-market activity, that is, whether to earn such income through its controlled foreign corporations (CFCs) or through its US-based operations. For income earned by a domestic corporation through its CFCs, section 250 provides a deduction of 50%* of GILTI (including the section 78 gross-up).

For income earned by a domestic corporation through its U.S.-based operations, section 250 provides a deduction of 37.5% of FDII. The percentages are reduced to 37.5% (GILTI) and 21.875% (FDII) for taxable years beginning after 31 December 2025.

The section 250 deduction is limited if a domestic corporation’s taxable income (not taking into account the section 250 deduction) is less than the sum of its GILTI and FDII.

Section 250 Deduction = 50% of (GILTI + Section 78 gross-up) + 37.5% of FDII
