How do I request a tax filing extension?
If you need more time to file your federal tax return, you can request a tax filing extension directly with the Internal Revenue Service (IRS).
An approved extension gives you up to six extra months to file, but it doesn’t extend the deadline to pay any taxes you owe.
Which form do I use to request an extension?
To request a federal tax filing extension, you’ll use IRS Form 4868.
Form 4868 applies to individual federal income tax returns and is used to request additional time to file.
How can I file Form 4868?
You can request a tax extension in a few different ways:
File electronically
You can submit Form 4868 online through:
The IRS Free File program, or
An IRS-authorized e-file provider
File by mail
You can also:
Print and complete Form 4868
Mail it to the IRS address listed in the form instructions
If you mail your form, make sure it’s postmarked by the original tax filing deadline.
When is the deadline to request an extension?
The deadline to request a tax extension is the same as the original tax filing deadline, usually April 15.
If you miss this deadline, the IRS may not approve your extension.
Should I include a payment with my extension?
Yes, if you expect to owe taxes.
An extension only gives you more time to file—not more time to pay. Paying as much as you can by the original deadline helps reduce penalties and interest.
You don’t need to pay the full amount to request an extension, but underpaying can lead to additional charges.
Do I need to explain why I’m requesting an extension?
No. The IRS doesn’t require a reason when you request an extension.
As long as Form 4868 is filed correctly and on time, the IRS will usually approve it automatically.
What about state tax extensions?
State tax extension rules vary.
Some states accept the federal extension, while others require a separate state extension request. Check your state tax agency’s website to confirm what’s required.
Key takeaway
Requesting a tax extension is a simple way to get more time to file your return. Just remember to submit Form 4868 by the original deadline and pay as much as you can to avoid penalties and interest.
