How do I fix e-file reject SEIC-F1040-506-02?

SOLVEDby TurboTax362Updated February 01, 2022

If you receive e-file reject code SEIC-F1040-506-02, your return was rejected because on your Schedule EIC (Earned Income Credit), a qualifying child's social security number (Line 2) cannot be used more than once in a tax return or on another return.

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

Which parent claims the EIC?


Usually the custodial parent gets to claim the EIC, even if the noncustodial parent is claiming the Child Tax Credit per divorce decree or other agreement.  If you feel you're the parent who is entitled to claim the EIC, go ahead and paper-file your return as is, since you won't be able to successfully e-file it.

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

If the other person rightfully claimed your child for EIC purposes we'll show you how to fix your return to remove the EIC from your return.
