An extension request filed after the filing deadline for your return will be invalid.

How to request your extension

  • You can complete your request for free using our online service.
  • You must e-file your extension if you prepare your extension using software that supports e-file.
  • If your paid preparer is required to e-file your tax return, and is also preparing your extension request, the preparer must e-file your extension request.

The online and e-file options provide you with a confirmation that we received your extension request.

Fiscal year filers should contact us to request an extension.

Payment of tax

You must make full payment of the properly estimated tax balance due when you request your extension of time to file.
