[1] The Tax Cuts and Jobs Act of 2017 ("TCJA") established the Global Intangible Low-Tax Income ("GILTI") provision, which taxes U.S. allocated expenses and certain income from foreign operations; the Foreign-Derived Intangible Income ("FDII") provision, which allows a deduction against certain types of US taxable income resulting in a lower effective US tax rate on such income; and the Base Erosion Anti-abuse Tax ("BEAT"), which is a new minimum tax based on cross-border service payments by U.S. entities.
