The IRS has rejected the return because the Qualifying Child's SSN on Schedule EIC (Form 1040) has already been used on another accepted return for the same tax year.
Possible Cause:
The Qualifying Child has been claimed for the Earned Income Credit (EIC) by another taxpayer.
✅ Steps to Resolve:
Confirm Eligibility – Verify if the taxpayer is legally entitled to claim the child for EIC purposes.
Modify the Return:
Remove the dependent from the return.
Indicate that the taxpayer does not qualify for the EIC.
Paper Filing Option:
If the taxpayer believes they have the right to claim the child, they must file the return by mail, including an explanation to support their claim.
