Form 7004 — Multiple extensions filed in the same tax year

A taxpayer who needs to file Forms 7004 for multiple form types may submit the Forms 7004 electronically. For example, taxpayers submitting one Form 7004 with "Type of Return Code" 31 for the Form 8804 and another Form 7004 with "Type of Return Code" 09 for the Form 1065 may file the forms electronically.  But the taxpayer may submit only one Form 7004 for each form type.  So, if the taxpayer files two Forms 7004 for “Type of Return Code” 09, the second Form 7004 will reject as a duplicate.
