The IRS rejects e-filed returns that contain incorrect, mismatched, or already-filed Social Security numbers, birthdates, or names. Here are a few ways this can happen:
- You accidentally entered the wrong Social Security number or date of birth
- The name or date of birth you entered doesn't match IRS records for that Social Security number
- A former spouse claimed your dependent on their return and filed before you did
- Your dependent already claimed himself/herself on their own return (or your parent already claimed you as their dependent) and filed before you did
- Someone else filed their return using your, your spouse's, or your dependent's Social Security number
If you verified that the info you entered is correct and you e-file again, the IRS e-file servers will almost certainly reject your return for the same reason. In this case, your only option is to paper-file (mail) your return. See the articles below for more info on commonly-encountered rejections caused by incorrect, mismatched, or already-filed personal info.
Important: If you believe someone filed a fraudulent return using your Social Security number, we have recommended actions.
