You can (and should) “validate” your filing before submitting it. The automatic validation will perform an initial check for errors, such as if Schedule H numbers are not consistent within Schedule H or with the Form 5500. This is a check of errors in your filing before you submit it to the Government. If the errors/warnings are not corrected before submission, the Government will be alerted to the errors associated with your filing when it is submitted. Please run the pre-validation check and correct any errors/warnings to the best of your ability before you submit your filing.
After a filing is submitted to EFAST2, the Government may perform additional checks of the annual return/report, and your filing may be rejected based on these additional checks.
