Persuading the IRS to give you more time after the April deadline to file your tax return is fairly easy. But there are several other things you’ll need to do if you’re filing taxes late.
How to get a tax extension
- File Form 4868.
- Set aside cash for interest.
- Prepare to pay a penalty of 0.5% per month that your outstanding taxes are late.
- Make sure you file your return by the October deadline.
- Be aware of special situations that give you an automatic extension.
Get the form
This is the easy part. You just have to file Form 4868 by the April deadline, and you’ll get a tax extension until October. But the work doesn’t end there.
Set aside cash for interest
When you file for an extension, make a good estimate of what you owe the IRS and send some or all of that amount along with your extension request in April. If the estimated payment you send in April ends up being less than what you actually owe, you’ll need to pay interest on the difference.
“The interest runs until you pay the tax. Even if you had a good reason for not paying on time, you will still owe interest,” the IRS says on its extension form.
Prepare to pay a tax penalty, too
The IRS’s late-payment penalty normally is 0.5% per month of the outstanding tax not paid by the April deadline. The maximum penalty is 25%.
You might catch a break on the penalty if you’ve paid at least 90% of your actual tax liability by the April deadline and you pay the rest with your return. The IRS also might let you off the hook if you can show “reasonable cause” for why you didn’t pay on time — though you’ll need to attach a written statement to your return.
Circle Oct. 15 on your calendar
If you get an extension, Oct. 15, 2020, is the last day you can file your return and pay your outstanding balance. Don’t miss your deadline! Otherwise, the IRS can sock you with a late-filing penalty of 5% of the amount due for every month or partial month your return is late. That means if you owed an extra $1,000, you could rack up $50 in penalties for every month after October that it’s outstanding. The maximum penalty is 25% of the amount due. In our example, that can mean shelling out an extra $250.
If you file your taxes more than 60 days late, you’ll pay either $435 (adjusted for inflation) or what you still owe, whichever figure is smaller. And remember, that’s on top of what you still owe in taxes.
The good news is that the IRS may throw you a lifeline: You might not have to pay the penalty for late taxes if you have “a reasonable explanation” for filing late, so again, you’d need to attach a written explanation to your return.
Also, you don’t need to wait until October to file the return. Organize your tax life and file and pay as soon as you can, and you’ll pay less in interest.

Relax if you’re abroad or in the military
For virtually anyone who files late taxes, forgetting to request an extension is a huge no-no. But if you’re a U.S. citizen or resident who lived and worked outside of the country on the April deadline, you automatically get two extra months to file your return and pay any amount due without having to request an extension. People affected by certain natural disasters may automatically get more time as well (check the list of qualifying disasters here). Some members of the military also get more time, depending on where they are and what they’re doing (learn more here).
Lift your chin up
Procrastination isn’t the only reason people get extensions. For example, many investors don’t receive their K-1s, which are statements of income from partnerships, until after April.
So, assuming you remembered to request an extension by the April deadline, filing your taxes later doesn’t put some sort flag on your “record.”
