A tax filing extension gives you more time to file your return, but it does not give you more time to pay any taxes you owe.
If you request an extension, the Internal Revenue Service (IRS) allows you up to six extra months to submit your federal tax return.
Even if you file an extension, any tax you owe is still due by the original filing deadline—usually April 15.
What does a tax extension do?
A tax extension:
Gives you more time to file paperwork
Helps you avoid the failure-to-file penalty if approved
A tax extension does not:
Extend the deadline to pay taxes owed
Stop interest from accruing on unpaid balances
Even with an extension, paying as much as you can by the original deadline helps reduce penalties and interest.
How long is a tax extension?
A standard federal tax extension gives you six additional months to file your return.
For most taxpayers, that moves the filing deadline from April 15 to October 15.
Do I need a reason to request an extension?
No. The IRS doesn’t require you to explain why you need an extension.
As long as you submit your extension request on time and complete it correctly, the IRS will usually approve it automatically.
Do extensions apply to state taxes too?
Maybe. State tax rules vary.
Some states automatically grant an extension if you file a federal extension, while others require a separate state extension request.
Check your state tax agency’s website to confirm what’s required.
Key takeaway
A tax extension gives you more time to file—but not more time to pay. If you need extra time to gather documents or finalize details, requesting an extension can help you avoid late filing penalties, as long as you pay what you owe by the original deadline.
