IRS Reject Code R0000-504-02

R0000-504-02

This reject code indicates a mismatch between a dependent’s SSN and the first four letters of their last name. As with the primary and secondary taxpayer, the IRS uses data provided by the SSA to verify the name and SSN. The reject message will indicate the dependent in question, so if the message says, “Additional Information: XXX-XX-1234”, the dependent whose SSN ends in 1234 is the one triggering the reject.

To correct Reject Code R0000-504-02:

  • Verify the dependent’s last name and SSN or ITIN with their social security card or ITIN card. If the data entered on the return is incorrect, make the correction and retransmit the return. If the SSN is correct and the name contains more than three words, the SSA may be differently construing which name in the series is the last name. Try the middle name as the last name.
  • If you have verified the information and the return is still being rejected, advise the taxpayer to contact the SSA to verify the dependent’s last name. If a correction is required, it may take the SSA up to 10 days to notify the IRS after they have updated their files. Afterward, an electronic return can be resubmitted.
  • If the information in the return is entered correctly, the return will need to be paper filed. The taxpayer will need to liaise with the SSA to verify and/or correct the dependent’s information on file. They can call the SSA at 800.772.1213 or check here for a local SSA office that can assist.
