Haven't Filed Your Taxes Yet? You Still Have Time to Get an Extension From the IRS

Need more time to file your taxes? Good news: It's surprisingly easy to ask the IRS for a later due date.
In fact, if a few days of wiggle room is all you need, you're in luck. Although Tax Day is usually April 15, most folks' taxes are actually due Monday, April 18, this year because of Emancipation Day, a recognized holiday in Washington, D.C. Due to tornadoes, wildfires and other natural disasters, residents in a few states have additional time to file, as well.
But if that won’t cut it, you’ll need to request a tax extension from the IRS to get more time to get your 2021 taxes in order. Here’s how.
Requesting a tax extension from the IRS
Before we dive deeper, you should know this from the outset: A tax extension will only push back the deadline for you to file your tax return by six months. That extension will not change the due date for any money you need to pay the IRS.
In other words, a tax extension will give you until Oct. 17 this year to get your paperwork together and file your return.
The extension process varies depending on if you overpaid taxes — and expect a tax refund — or underpaid taxes — and owe the IRS money.
If you expect a tax refund
The majority of taxpayers receive refunds from the IRS, so it’s likely you’ll need to file your extension following these guidelines. Requesting an extension to file your tax return is relatively simple. You can do so online or by snail mail.
However, online methods are highly recommended, as the IRS has a massive paper backlog. (The National Taxpayer Advocate, the IRS’s internal watchdog, recently called paper the “IRS’s kryptonite” because the agency lacks the proper infrastructure to process physical forms in a timely fashion, leading to major delays for millions of people.)
For online tax extension requests, you can get started by using the IRS’s Free File tools. You’ll have two main options:
- If you have an adjusted gross income (AGI) of $73,000 or less, you can use guided tax software to submit your request and avoid filling out any forms directly.
- If you have an AGI above $73,000 — or prefer to fill out the request yourself — you can use the IRS’s Free Fillable Forms tool to manually complete and submit Form 4868, aka the extension request form.
If you’re unable to submit your extension request online, you can print Form 4868 and fill it out by hand. Then, mail the completed form directly to the Department of Treasury. The exact IRS location you’ll need to mail it to depends on your state; you’ll find the corresponding address on the last page of the form.
If you owe the IRS
Should you owe the IRS, you will still need to make a payment by April 18 or face penalties and interest. When you make a payment — or pay your tax bill entirely — the IRS automatically processes a tax extension for your return, meaning you won’t have to fill out any additional forms to request more time.
However, let’s say you’re not sure if you’re going to be able to submit your payment by Tax Day. In this case, you would need to request an extension.
The process is the same as outlined above: You can use the IRS's Free File tools or mail in Form 4868. If you’re not using tax prep software and actually have to fill out the paperwork, prepare to do a little math. On lines No. 4 through No. 7, you’ll need to estimate how much you owe and the amount you’re going to pay. (Note: That doesn't mean you have to include payment with this form. It’s only an estimate.)
Finally, the IRS provides short-term and long-term payment plans for those who are struggling to pay their tax bills by the deadline. Enrolling in a plan can help you mitigate significant tax penalties.
