You can file an IRS tax extension online for free through the IRS Free File program at IRS.gov/freefile. This gives you until October 15 to file your federal tax return, but you need to submit the extension request by the April 15 deadline. There are several free methods available, and the whole process takes just a few minutes.
Use IRS Free File to Submit Form 4868
The most straightforward way to file a free extension is through the IRS Free File program. Anyone can use it to file an extension, regardless of income. You have two options within the program: Guided Tax Software, which walks you through the process with a partner company, or Free File Fillable Forms, which lets you fill out Form 4868 directly.
The IRS partners that currently offer free extension filing include 1040.com, 1040Now, FileYourTaxes.com, OnLine Taxes, and TaxAct. To access these partners at no cost, you must start at IRS.gov/freefile. If you go directly to a partner’s commercial website, you won’t get the free version and may be charged a fee. Once on the IRS Free File page, use the “Find your trusted partner” tool or browse the full list of providers, then follow the prompts to file your extension.
File Automatically by Making a Payment
If you owe taxes and plan to make a payment, you can skip Form 4868 entirely. The IRS automatically processes an extension when you make a payment and indicate it’s for an extension. You can do this through IRS Direct Pay (which pulls directly from your bank account), or by paying with a debit card, credit card, or digital wallet through the IRS payment page.
IRS Direct Pay is completely free and doesn’t charge processing fees. Credit and debit card payments go through third-party processors that charge a small fee, so Direct Pay is the better option if you want to keep things free. Either way, the IRS treats your payment as an extension request, and you won’t need to file a separate form.
What an Extension Does and Doesn’t Do
An extension gives you six extra months to file your return, pushing the deadline from April 15 to October 15, 2026. It does not give you extra time to pay. Any taxes you owe are still due by April 15, and interest starts accumulating on unpaid balances after that date, even if you’ve filed an extension.
To minimize penalties, estimate your total tax liability before filing the extension. Look at your income for the year, subtract any taxes already withheld from paychecks or paid through estimated quarterly payments, and pay whatever balance remains by April 15. You don’t need an exact number. A reasonable estimate that covers most of what you owe will significantly reduce any interest charges. The failure-to-file penalty is much steeper than the failure-to-pay penalty, so filing the extension even if you can’t pay the full amount is always better than doing nothing.
Special Rules for Military and Overseas Filers
If you’re a member of the military serving outside the United States and Puerto Rico, you automatically get a two-month extension to file, pushing your deadline to June 15 without needing to submit any form. U.S. citizens and resident aliens living and working abroad get the same automatic two-month extension. In both cases, interest still applies to any unpaid balance after April 15, so paying on time matters even when the filing deadline is extended.
State Extensions May Be Separate
Filing a federal extension doesn’t automatically cover your state taxes. Some states grant an automatic extension when you file one with the IRS, while others require you to submit a separate state extension form. A handful of states let you file your state return after the deadline without requesting any extension at all. Nine states have no income tax, so there’s nothing to extend. Check your state’s tax agency website to find out whether your federal extension is enough or whether you need to take an additional step.
Step-by-Step Summary
- Go to IRS.gov/freefile. Do not go directly to a tax software company’s website, or you may be charged.
- Choose a Free File partner or use Fillable Forms. Select whichever option you’re comfortable with. Guided software is easier if you’re unsure what to enter.
- Complete Form 4868. You’ll need your name, address, Social Security number, and an estimate of your total tax liability for the year.
- Pay any balance due. If you owe taxes, pay as much as you can by April 15 through IRS Direct Pay or another payment method to avoid interest.
- Save your confirmation. Keep a record that your extension was accepted. You’ll receive a confirmation number after submitting electronically.
The entire process typically takes under 10 minutes. Once accepted, your new filing deadline is October 15, 2026, giving you a full six months to gather documents and complete your return.
