A clear explanation of each change
Your PDF. Its purpose.
Both Form 1040-X pages present the previously reported amounts, corrections and explanation entered in the builder. Review the change as a complete trail from the filed return to the figures now being reported.
The PDF does not include a complete corrected return, all supporting forms, filing services, payment processing or refund approval.
Check the official IRS 1040-X information and instructions for filing requirements and supporting worksheets.
