What is Form 4868 and how does it extend your 1040?
If you need more time to file your 1040 forms, you can get an extension by using Form 4868 (Application for Automatic Extension of Time to File U.S. Individual Income Tax Return). This IRS form generally gives you an automatic 6-month extension to file your individual income tax return. If you are outside the U.S., you may already qualify for an automatic 2-month extension and can use Form 4868 to request an additional 4 months.
Form 4868 also extends Form 709/709‑NA filing time when you extend your individual return. However, it doesn’t extend the time to pay gift/GST tax.
You can file Form 4868 online for the fastest confirmation but estimated tax payments are still due by the original date even if you’re using the IRS tax extension deadline to file later. If you don’t pay on time, you’ll owe interest and may be charged with penalties.
Which returns does Form 4868 cover (1040‑series)?
Form 4868 can extend the filing deadline for these 1040-series individual returns:
| Form | Reports |
|---|---|
| 1040 | An individual’s annual income, calculates deductions, credits, and determines tax owed or refund. |
| 1040-SR | Similar to 1040 reporting requirements but is designed specifically for individuals who are 65 years or older. |
| 1040-NR | Income, deductions, and tax liability earned in the U.S. by non-resident individuals. |
| 1040-SS | Self-employment income and calculates Social Security and Medicare taxes of eligible citizens in Puerto Rico, Guam, the U.S. Virgin Islands, and American Samoa. |
Original and Extended 1040 deadlines
Here are the Form 4868 deadlines for 2025 tax year (to be filed in 2026).
| Type of Year and Taxpayer | Original Deadline | Extended Deadline After Filing Form 4868 |
|---|---|---|
| Calendar year taxpayer | April 15, 2026 | October 15, 2026 |
| Fiscal year taxpayers | 15th day of the 4th month after fiscal year ends | 6 months from the original due date |
| U.S. taxpayers outside the U.S. | June 15, 2026 (automatic 2-month extension without filing Form 4868) | October 15, 2026 (if Form 4868 filed) |
Special Cases
- Fiscal‑year individuals: If you are an individual taxpayer who uses a fiscal year, you need to paper‑file Form 4868.
- U.S. citizens living abroad: You generally get an automatic 2-month extension to file if you are out of the country on the due date. Filing Form 4868 can give you an additional 4-month extension to file, but it does not extend the time to pay.
- Combat zone & contingency operations: If you’re serving in a designated combat zone or contingency operation, your 1040 filing and payment deadlines are generally extended for the period of service, plus 180 days. For hospitalization from an injury caused during service, the 180-day period begins after hospitalization ends.
- Disaster declarations: If you were affected by a disaster, you get an automatic deadline extension set by the IRS.
Note: The due date moves to next business day if it falls on a Saturday/Sunday or legal holiday.
Penalties If You Miss the 4868 or 1040 deadline
Failure‑to‑file penalty
If you fail to file Form 1040 or its variants on time, you may have to pay a penalty of 5% of the unpaid tax for each month, or part of a month, that the return is late, up to 25%.
For returns that are more than 60 days late, the minimum penalty is the amount shown in the current IRS Form 4868/Form 1040 instructions, or the balance of the tax due on your return, whichever is less.
Failure-to-pay penalty
If you still owe tax after the regular due date, the penalty is 0.5% of the unpaid tax per month (or part of a month) after April 15, up to 25%.
90% rule
If you pay at least 90% of your total estimated tax by the original due date (April 15 in most cases), the late‑payment penalty is waived during the extension period. However, you may still have to pay interest.
Requesting an Extension: E-filing or Paper Filing
As explained in the 2025 IRS Form 4868 instructions, there are two ways to request an extension: e-file (IRS-recommended) or paper file (required for fiscal-year filers).
