Rejection SEIC-F1040-506-01: On Schedule EIC, the qualifying child's social security number (Line 2) cannot be used more than once in a tax return or on another return

This rejection occurs when you try to claim the Earned Income Credit (EIC) for a child on your return, but that child has already been claimed for the EIC on another return.

Usually the custodial parent gets to claim the EIC, even if the noncustodial parent gets to claim the dependent exemption and Child Tax Credit per divorce decree or other agreement.


If the other (custodial) parent has already used your child to claim the EIC, here's how to remove your child from the EIC while still keeping the dependent exemption and Child Tax Credit:

  1. Open (continue) your return in TurboTax.
  2. You'll be prompted to confirm the status of your return(s). Click Continue.
  3. At the Rejected message, click Personal Info near the top (not the "Help Me Fix It" button).
  4. On the Your Personal Info Summary screen, click Edit next to the dependent(s), then Edit again on the following screen for the dependent in question.
  5. Proceed to the Tell Us a Bit More About [child's name] screen. On this screen, select 5 (or a lower number), then Continue.
  6. Keep answering the questions until you get to the Your Children and Others You Support screen, then click Done.
    • Note: If you're told that your dependent doesn't qualify, go back and make sure you've answered the questions correctly (especially the ones about living expenses).
  7. Now click File near the top and follow the onscreen instructions to proceed with the filing process.

Otherwise, if you feel you are entitled to claim the EIC, go ahead and paper-file your return. You won't be able to e-file it.

Eventually, the IRS will contact both parties to determine who gets to claim the EIC, and the unentitled taxpayer will have to repay any taxes owed, as well as possible penalties and interest, that resulted from the duplicate EIC claim.
