E-file reject R0000-507-01: A dependent on your return has already been claimed (or claimed themselves) on another return

This usually means that someone else, such as an ex-spouse, has already claimed your dependent. For confidentiality reasons, the IRS is unable to disclose who that person is.

Less commonly, you can get an R0000-507-01 rejection if you entered a dependent's Social Security number incorrectly or if somebody filed a fraudulent return using your dependent's Social Security number.

Solution

To remove an already-claimed dependent:

  1. Sign in to TurboTax if you haven't already signed in.
    • Click or tap any orange "Fix" buttons you see before proceeding to Step 2.
  2. At the Welcome back to TurboTax message, click or tap Personal Info near the top (not the gray "Fix It Now" button).
    • Mobile devices: Tap the upper-left corner to open the side menu, then tap Personal Info.
  3. On the Personal info summary screen, click or tap Delete to the right of the dependent, answer Yes, then Done.
  4. Next, click or tap Review near the top (on mobile devices, tap the upper-left corner to open the side menu, then Review).
  5. Step through the review section; when finished, we'll move you to the File section where you can e-file your return again.
    • Note: Do not select "Fix my return" in the File section (you've already done that).

Otherwise, if you want to claim the dependent:

  1. Sign in to TurboTax if you haven't already signed in.
    • Click or tap any orange "Fix" buttons you see before proceeding to Step 2.
  2. At the Welcome back to TurboTax message, click or tap Fix It Now.
  3. Compare your dependent's SSN to the number on their Social Security card.
  4. Follow the onscreen instructions to either correct their Social Security number and re-file, or file a paper return.

What happens if I answer "Yes" (their SSN is correct)?

We'll walk you through paper-filing your return because the e-file server won't let the same SSN go through twice.

The IRS will eventually contact both claimants to determine who rightfully gets to claim the dependent. Once they've figured it out, one of you will have to repay any additional taxes (plus possible penalties and interest) attributed to the duplicate claim.

What if I don't know who claimed my dependent?

It's likely that somebody filed a fraudulent return using your dependent's information. Please contact us right away for further assistance.
