This year, we also filed Form 7004, which automatically applies to our NJ State return as well. The instructions for NJ 1065 say "A copy of your application for federal extension, federal Form 7004, must be filed with your New Jersey return. Check the box labeled “Application for federal extension is attached” on the front of your NJ-1065."
I did check the appropriate box, but that again leaves me wondering how to attach the 7004 form? Is there really no way to attach this form, and if so do I need to file by mail just because of this?
