IRS Form 12153 is a consent form that allows a taxpayer to extend the filing deadline for a specific tax return under IRC §6501(e). It is used when the IRS has granted an extension but the taxpayer must agree to the new deadline.
Plain English
If the IRS says you can file a return later than the usual due date, you sign Form 12153 to accept that new deadline. Without this consent, the extension isn’t valid and penalties could apply.

Requesting a standard six‑month extension
Used for most individual returns
✓ Verify you are not already under a §6501(e) offer
Changing an already‑granted extension date
Must reference original extension notice
✓ Confirm the new date is later than the original deadline
The consent must be received by the original filing deadline for the extension to be effective. If the original deadline is missed, the extension is automatically invalid and penalties may apply. The IRS does not provide a separate deadline for the consent itself; it must accompany the extension notice before the original due date.
