NOTE: The IRS has issued a statement asking preparers to HOLD OFF on filing 1040X returns due to the American Rescue Act
This amended return cannot be filed electronically. Please submit a paper amended tax return. To find a proper mailing address, go to irs.gov/file.
There are four reasons Form 1040-X might reject with this code:
- The filing status on the amended return differs from the original return.
- The original return was not e-filed.
- The original return was not a Form 1040 or 1040-SR.
- The primary taxpayer SSN and/or the spouse SSN don’t match the original return.
Meaning: The IRS has placed a hard stop on the primary SSN for some reason. The 1040X will have to be filed via paper
