IRS Tax Return Rejection Code R0000-507-01

Problem: The IRS—not—rejected your Federal Tax Return because a dependent on your return has already been claimed by another person OR the dependent filed their own return and did not indicate that they can be claimed as a dependent on another person's return.

Solution: Let us help you turn this into an IRS acceptance. Sign into your account at and click Federal Taxes on the left side menu in your account. Then, open the Dependent tab to see your child or dependent(s). You can then verify that the dependent information is correct and/or remove the dependent that cannot be claimed.

Note: This does not necessarily mean someone had the right to claim the dependent. If this is the case, you will need to PRINT your return from your account, sign it, and mail it to the IRS, because the IRS e-file system will reject your return as it is now until the other return is amended. Find the right address to use based on your resident state. You may need to print, sign, and mail your State Tax Return to the State Tax Agency as well.
