Form 4461‑C is the IRS application for an automatic 6‑month extension to file a foreign corporation’s Form 1120‑F. Use it when you cannot meet the original filing deadline for the foreign corporation’s income tax return.
Plain English
If a foreign company that must file Form 1120‑F needs more time, it sends this short form to the IRS asking for a six‑month grace period. The request must be filed before the original due date, and the IRS will grant the extension automatically if the form is complete and the required fee is paid.
