The delay is due to data migration issues that were found during testing.
HMRC said: “This means that we must postpone the delivery of these changes until these migration issues can be fixed. As such the planned downtime scheduled from midday Friday 2 August 2024 to 10am Monday 5 August 2024 is cancelled.”
There will be no loss of service.
HMRC will provide an update on the new deadline as soon as the data migration issues have been resolved.
