Per-Country Minimum Act This bill modifies the tax treatment of foreign source income of domestic corporations to: (1) increase taxes that apply to global intangible income by reducing the deduction that is allowed under current law, (2) eliminate a provision that allows companies to deduct a portion of the tangible assets of their controlled foreign corporations (CFCs) before the tax on foreign income applies, and (3) require net CFC tested income to be determined on a country-by-country basis rather than globally.
