Non filer tool e file rejection and accepted extension?

[Kthane]

Im confused. If the non filers tool submitted an actual return, causing an efile unsubmittable due to a “return already being submitted”then WHY WAS AN EXTENSION ACCEPTED???

It was was done just to confuse you. Apparently it worked.

Maybe someone needed to request an extension for purposes of filing a stand-alone Form 5329 or Schedule H.

More likely, IRS didn't anticipate so many greedy people would claim to be nonfilers so they could collect $1,200, then come back and admit they have to file.  Just because the extension is accepted, doesn't mean they can avoid the extra scrutiny of a paper return.

"If the non filers tool"

Whose tool? The IRS tool was only a portal. TurboTax, H&R and Tax Act would have filed a basic return, though.
