IRS Form 4868 2025 – If you need more time to file your 2025 federal income tax return, IRS Form 4868 is the simple, automatic way to get a 6-month extension. As a U.S. taxpayer, filing this form by the April 15, 2026 deadline gives you until October 15, 2026 to submit your Form 1040, 1040-SR, 1040-NR, or 1040-SS—without late-filing penalties.
Important reminder: Form 4868 only extends the time to file your return. It does not extend the time to pay taxes owed. You must still pay any estimated tax due by April 15, 2026, to avoid interest and penalties.
This 2025 guide (based on the official IRS Form 4868 revision dated October 1, 2025) walks you through everything: who needs it, step-by-step instructions, how to file, and direct links to the free printable PDF.
What Is IRS Form 4868?
Form 4868 is officially titled “Application for Automatic Extension of Time To File U.S. Individual Income Tax Return.” It lets U.S. citizens and residents request an automatic 6-month extension for calendar-year 2025 taxes (or the appropriate fiscal-year period).
The extension also covers:
- Gift and GST tax returns (Form 709 or 709-NA) for 2025
- But not payment of gift/GST tax (use Form 8892 for that)
No IRS approval is needed—the extension is automatic if you file correctly and make a reasonable estimate of your tax liability.
Who Should File IRS Form 4868 in 2025?
File Form 4868 if you:
- Are a U.S. citizen or resident
- Need extra time to gather documents, calculate deductions, or complete your return
- Expect to owe taxes but want to avoid late-filing penalties
Special cases:
- U.S. citizens/residents living outside the U.S. and Puerto Rico on April 15, 2026, get an automatic 2-month extension (to June 15, 2026) without filing Form 4868. Check box 8 on the form for an additional 4 months (total 6 months).
- Form 1040-NR filers with no U.S. wages subject to withholding may have a June 15, 2026 due date—check box 9.
Do NOT file if you are under a court order to file by the original due date or want the IRS to calculate your tax.
