I have an s-corporation that is a fiscal year entity ending 09-30.

Their 09-30-2012 year end has been extended and isn’t finished yet.

I plan to revoke their fiscal year election in 2012 meaning they’ll have to file a short “calendar year” 2012 corporate return.

I’ve attempted to extend that short calendar year return by electronically filing form 7004.

It was rejected because IRS thinks they’re on a fiscal year.

I now plan to mail the extension with an attachment explaining the situation.

Is there a better way to handle this?
