A provider may be unable to submit their returns if required fields are incomplete, validation checks have failed, or there are permission or access issues preventing the submission from being finalised.
If you are unable to submit your provider returns please be sure every question has been answered, some questions will be set as optional and some will be set to must have an answer.
If you have answered every question but still receive the error, please try submitting the return on an alternate browser, or try submitting on a different computer.
If you are certain every question has been completed but you still cannot submit the provider return please raise a new case online and reference the title of this article including the name of the form you are trying to submit.
