E-file rejection error SEIC-F1040-506-01: Schedule EIC qualifying child's SSN used more than once

How to fix an e-filed return that was rejected with error code SEIC-F1040-506-1: 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.

Most commonly, this rejection occurs when your qualifying child has already been claimed on another tax return.

It can also occur if the wrong child's Social Security number was entered, or if the same number was entered for two different children.

Solution

  1. Open your return and click Personal Info.
  2. Proceed to the Your Personal Info summary screen.
  3. Next to About Your Dependents, click Edit.
  4. For each dependent, click Edit and then make sure that each dependent's Name and Social Security number exactly matches the information on their Social Security card.
    • If the information is correct, proceed to Step 5.
    • Otherwise, click the Edit button, make the correction(s), and continue until you're back on the Your Personal Info summary screen. Then, e-file your return again.
  5. Call the Social Security Administration (SSA) at 1-800-772-1213 to verify the Social Security number, date of birth, and name for all dependents.
    • If the information differs from what you entered, update it in TurboTax to reflect the SSA's information and then re-file your return.

Otherwise, if you verified that your dependents' information is correct, you can be certain another taxpayer, such as an ex-spouse or caregiver, has already claimed your dependent(s) on their return. Here are your next steps.

  1. First, make sure you can claim this dependent and that the other person (if known) cannot.
    • If you discover you cannot claim this dependent, delete the dependent from your return and then re-file your return.
  2. If you believe you can rightfully claim the dependent, print and mail your return, as you will not be able to e-file it.
    • The IRS will process your return as usual, and issue your tax refund if you are getting one.
    • In a few months, the IRS will contact you as well as the other person to determine who is legally entitled to claim the dependent.
    • The person who illegally claimed the dependent will be required to repay any additional taxes, plus penalties and interest, that were attributed to the false claim.
