How to e-file the extention with home and business desktop for 2025 taxes?

[VolvoGirl]

Extensions from the Desktop program must be printed and mailed.

Or use the online "Easy Extension".

You can still use the free online extension and efile it if you are using the Desktop program.  The extension doesn't need to be in noted in your return unless you sent in a payment in which case you have to manually enter the payment.

You cannot e-file an extension request using desktop software, but you can use online to e-file an extension request.

An extension does not give you extra time to pay your estimated tax due—-which must be paid by April 15, 2026.  An extension gives you extra time to prepare your tax return.  You have until October 15 to e-file it.
