Deadline or filing window

The extension request must be received by the IRS on or before the original Form 1120‑F due date (typically the 15th day of the 4th month after the corporation’s tax year ends). If the request arrives late, the extension is denied and penalties may apply. The six‑month extension runs from the original due date, not from the filing date of Form 8596.
