Form 1120-F: U.S. Income Tax Return of a Foreign Corporation

For foreign corporations conducting business in the United States, Form 1120-F must be filed to report income, deductions, credits, and figure U.S. tax liability. Unless one of the exceptions applies, a foreign corporation must file Form 1120-F to report engagement in a U.S. trade or business, effective connection with a U.S. trade or business, or income from U.S. sources.

What is Form 1120-F?

Form 1120-F is used by foreign corporations to report income, gains, losses, deductions, and credits, and calculate any U.S. income tax liability. It is also used to claim refunds and calculate a foreign corporation’s branch profits tax or tax on excess interest. It must be filed by a foreign corporation unless it meets certain exceptions such as full U.S. tax being withheld at source or its only U.S. source income being exempt from U.S. taxation. Other entities such as a beneficiary of an estate or trust or a mutual life insurance company must also file Form 1120-F in certain instances. A foreign eligible entity that elected to be classified as a corporation or a corporation filing to claim a treaty or Code exemption must also file this form. A foreign corporation may also want to file a protective return to safeguard its rights to deductions and credits. Additionally, foreign corporations must file this form to certify as a qualified opportunity fund and attach Form 8996, and to hold a qualified investment in a qualified opportunity fund, they must attach Form 8997.
