For the past week, our online CT600 submissions have been rejected with an error message about the IR Mark being incorrect. According to the report we get out of IRIS, the IR Mark looks normal but there is no entry for the time. IRIS says it is a known fault, the Online Services Helpdesk say it is a known fault and the website Service Issues page says that the Revenue are working with their IT partners to resolve the issue.
Is this problem specific to IRIS?
Has anyone been able to find out when the problem is likely to be solved?
