A corporation formed in a US jurisdiction will be treated as a domestic corporation.

Domestic

A domestic corporation is subject to a modified territorial tax regime on US-source income and certain earnings related to foreign entities. A domestic corporation may be subject to tax on income of its foreign subsidiaries if the global intangible low-taxed income (GILTI) rules or another anti-deferral provision applies (ie, the CFC or PFIC rules).

Foreign

Foreign corporations generally are not subject to US tax except on

• Income effectively connected with the conduct of a US trade or business and
• Certain FDAP (fixed or determinable annual or periodical gains, profits and income, which is generally passive) income from US sources.

Tax treaties can reduce or eliminate these taxes.

Tax rulings

An industry issue resolution may be requested to provide generally applicable guidance on frequently disputed or burdensome business tax issues affecting a significant number of taxpayers.

US corporate taxpayers earning foreign-derived intangible income (FDII) may qualify for a reduced effective tax rate on such income.
