Caseware Cloud Service, Performance Degradation for United Kingdom

Update timeline

1. investigating Feb 10, 2026, 04:22 PM UTC

   We are currently investigating an issue affecting live submissions for Corporation Tax and Companies House. At this time, non-admin users are unable to complete submissions because the “Authorise and Submit” button is not visible during the submission process. This issue does not impact admin users, who are able to submit as expected. We have also identified a related error in which some non-admin users may see an “insufficient rights” message when attempting to view staff member details. Our teams are assessing whether these behaviors are related. Our engineering teams have been able to reproduce the issue and are actively working to identify the root cause and implement a fix. There is currently no workaround available for non-admin users. We will continue to provide updates as progress is made and will share confirmation once the issue has been resolved.

2. identified Feb 10, 2026, 04:43 PM UTC

   The source of the Caseware Cloud Service Performance Degradation has been identified and we have found a potential solution. Work is currently underway to implement a fix, and validation efforts are in progress to ensure the solution fully restores expected functionality for non-admin users. We will provide a further update once the fix has been deployed tomorrow.
