Federal Income Tax Filing Extensions For Military Members in 2025

What follows is not tax advice. When in doubt, consult a tax professional.
For some military members, tax season is tricky. Challenges with deployments, permanent change of station orders, or serving abroad can affect your ability to gather needed documents on time, especially if you are serving in a combat zone or are at sea.
Fortunately, the IRS offers options to apply for extensions for qualifying military members. According to the IRS official site, those who need more time to file federal taxes should request an extension by the April tax filing due date (see below.) This gives you until October 15 to file.
Pay and Extend Online
If you are in the United States military and need to apply for a tax extension to file federal income taxes, you must apply by April 15.
Pay what you owe using an IRS online payment option and check the appropriate box on the online form. The IRS says, “You don’t have to file a separate extension form and you’ll receive a confirmation number of your extension for your records.”
Use Free File
Servicemembers can use IRS Free File to electronically request an automatic tax-filing extension online stateside or overseas.
Request by Mail
- File Form 4868, Application for Extension of Time To File U.S. Individual Income Tax Return
- Estimate how much tax you owe for the year on the extension form.
- Subtract the taxes you already paid for the filing year.
If you’re outside the U.S.
Some may qualify for an automatic 2-month extension if living out of the country on the regular due date of the tax return.
File an Extension Before April 15
If you already know you need an extension, apply for one before the IRS deadline of April 15, by downloading, filing and submitting IRS Form 4868. Follow the instructions on the form to extend your time by six months, creating a new due date of October 15, 2025, including those who are married and filing jointly. However, to avoid interest, taxpayers should pay before the original deadline.

How Long the Extension Lasts
This deadline extension lasts 180 days after departing the combat zone unless the status of said zone changes, the status of the contingency operation changes, or the tax filer receives injuries while serving there that result in hospitalization.
If you are redeployed during your six-month combat zone extension, you can re-extend your deadline if necessary.
All extensions except the combat zone extension allow for a later filing date but will not extend the deadline to pay taxes owed. Therefore, it is still necessary to make payment arrangements on time. Late payments can result in penalties of five to twenty-five percent of taxes owed.

For additional help, research military tax benefits using the IRS Publication 3: Armed Forces Tax Guide. In advance, reach out to see if your spouse needs a power of attorney if you are stationed far away to file on time or if you have extenuating circumstances. Also, review any documentation for credits that may help you get a better refund or owe less for the April 15 deadline, including:
- Child tax credit
- Child and dependent care credit
- The American Opportunity Tax Credit
- Adoption of a child
- Unreimbursed moving expenses
