IRS Reject Code R0000-500-01: primary taxpayer name or SSN mismatch

What does IRS reject code R0000-500-01 mean?

R0000-500-01 means the primary taxpayer's name or Social Security number does not match what the IRS has on file.

This is a name/SSN matching rejection. It is different from a rejection saying the SSN was already used on another return.

What should I check first?

1. Check the Social Security number. Look for a missing digit, transposed digits, or another typing error.
2. Check the name spelling. Compare the return with the Social Security card.
3. Check the name format. Make sure the surname and other name fields match the current Social Security record.
4. Review any recent name change. A marriage, divorce, or other legal name change may not yet match SSA records.

What if I recently changed my name?

The IRS says the name used on the return should match the name on the taxpayer's Social Security card. If the Social Security record has not yet been updated, use the name that matches the current SSA record or update the SSA record before filing.

What if the name and SSN look correct?

If you have checked the return against the Social Security card and the information appears correct, the underlying Social Security record may need review. The IRS directs taxpayers to contact the Social Security Administration when the entry is correct but the records do not match.

How do I fix R0000-500-01?

1. Save the complete rejection message. Confirm the exact code is R0000-500-01.
2. Confirm the person. This code applies to the primary taxpayer.
3. Compare the SSN with the Social Security card.
4. Compare the name spelling and format with the Social Security card.
5. Correct any entry errors.
6. If the return is correct but the record differs, contact the Social Security Administration.
7. Resubmit and review the new acknowledgment.

Can I correct the name and e-file again?

Yes. The IRS says errors such as a mistyped Social Security number or misspelled name can generally be corrected and the return can be electronically filed again.

What if I cannot get the e-file rejection corrected?

Some rejected returns may ultimately need to be filed by mail. If a paper return is filed after an e-file rejection near the filing deadline, IRS rules include special timing and documentation requirements. Review the current IRS rejected-return instructions before mailing.

R0000-500-01 vs. SSN already used

R0000-500-01 means the primary taxpayer's name/SSN combination does not match IRS records. An SSN already used rejection means that SSN appeared on another accepted return. Those are different problems and require different troubleshooting.

Common questions about R0000-500-01

Does this mean someone used my SSN?

Not necessarily. This code indicates a mismatch between the name/SSN combination on the return and IRS records. It does not, by itself, mean the SSN was used on another tax return.

Can a recent marriage cause this rejection?

Yes. If the name on the tax return does not match the current Social Security record, the return can reject. Compare the filing name with the Social Security card.

What if my Social Security card has my old name?

The IRS says the name used on the return should match the Social Security record. If the name has changed legally, update the Social Security Administration record as appropriate.
