Form 8879-EO is for an officer of an organization that is tax exempt. Many forms, including 990, 1120 and 8868, can be used with Form 8879-EO.


A person filling out an 8879 form either declares on the form that he will enter the personal identification number on an electronically filed tax return or authorizes another party, an electronic return originator, to do so.


All 8879 forms are to be retained by the taxpayer/signee. Form 8879 is not sent to the IRS unless the department requests it.
