Form 1120-F
U.S. income tax return of a foreign corporation engaged in U.S. trade or business.
In full
Form 1120-F is the income tax return filed by foreign corporations engaged in a U.S. trade or business or that owe branch profits tax. Even foreign corporations with no current-year U.S. activity often file a "protective return" to preserve the ability to claim deductions and credits in a later disputed year — those deductions and credits are allowed only if a return is filed on a timely basis, so a missing protective filing puts them at risk. The IRS Commissioner may waive that deadline where the corporation shows it acted reasonably and in good faith on the facts.
