Understanding IRS Reject Code X0000-029
If you receive IRS Reject Code X0000-029, it means that a file attached to the tax return is not in the correct PDF format. The IRS only accepts attachments that begin with the file header "%PDF-", which identifies a valid PDF file.
What Causes This Rejection?
This error occurs when an attachment in the return is not a PDF file. Common incorrect file types include:
Images (JPEG, PNG, GIF, etc.)
Text documents (DOC, TXT, etc.)
Spreadsheets (XLS, CSV, etc.)
How to Fix It
Find the incorrect file – Identify which attachment is causing the issue.
Remove the incorrect file – Delete it from the return.
Convert it to a PDF – Use a PDF converter or print-to-PDF option to ensure the file is in the correct format.
Verify the PDF file – Open it in a PDF reader to confirm it can be viewed properly.
Reattach the PDF – Upload the correct file and resubmit the return.
Final Check
Before resubmitting, always open the PDF to confirm it is readable and correctly formatted. This ensures a smooth e-filing process without further rejections.
Following these steps will help you resolve IRS Reject Code X0000-029 and successfully submit your return.
