When is the due date to file my Form 4868?

For the 2024 tax year, the due date to file your individual income tax extension Form 4868 is April 15, 2025.

Note:

• Fiscal year taxpayers: If you are a fiscal year taxpayer (a year ending on the last day of any month except December), the due date will be four months and 15 days after the close of your fiscal year. For example, if your tax period ended in April 2025, your due date to file Form 4868 would be August 15, 2025.
• Out-of-country filers: If you are a U.S. citizen or resident or a calendar-year income tax filer who is out of the country on the regular due date (April 15, 2025), you are automatically qualified for an extension until June 15, 2025, to file and pay any tax due without requesting an extension. If you need additional time beyond June 15, 2025, you must file Form 4868 by June 15, 2025, to receive an extension until October 15, 2025.
