I sent my paper returns via private delivery service (I have extension). I don't have tax due, and am getting a refund. The delivery service seemed to have misplaced my package and are investigating the incident. Since tax deadline is tomorrow, I am thinking of mailing a second return today. I am concerned however as to what happens if the first package with the delivery service ends up getting delivered to them also.
Is there extra process me or IRS has to take if duplicate returns show up? Can I send a return later after due date after the delivery provider's investigation is over considering I have no money due?
Thanks in advance
