When a file is rejected, that means we sent it to the IRS or SSA, and their rules kept it from being submitted.
You will get an email to the email address listed as your Notification Email in the My Account section of Helper. That email will include a "rejection reason."
Rejections do not need Corrections. When a form is rejected, it is not entered in the IRS or SSA records. Instead, you will need to edit the form so it complies with the rule it violates.
