Again it could have been a simple error by another person ... the IRS compares the first 4 letters of the last name, the birth year and the SS# so if someone made a key stroke error in any of these items then your return got rejected ... this happened to a client of mine who had a common last name and he gave me the SS# and one number was wrong and it was rejected as already used ... and when we corrected the SS# it went thru so you can see how easy it is to make a mistake ... if my client had filed first with the wrong number then the other person would have been rejected.
