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. Sign in to your account and select the Fix my return button.
  2. At the Welcome back to TurboTax message, select My Info in the left-hand menu.
    • Mobile devices: Select the menu icon in the upper-left corner, then select My Info.
  3. On the Personal info summary screen, select Edit next to the dependent in question.
  4. Proceed to the How many months did [child's name] live with you in 2017? screen. On this screen, select 5 months (or less), then Continue.
  5. Keep answering the questions until you get to the Your children and others you support screen, then select 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).
  6. Now select File in the left-hand menu (on mobile devices, select the menu icon in the upper-left corner, then select File).
  7. At the Welcome back screen, select Continue. (Do not select Fix my return you've already done that).
  8. 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.
