HMRC online service availability
23 September 2015
Due to a scheduled upgrade between 10.30pm 24 September and 1:30am on 25 September, users may experience a short disruption when attempting to log into HMRC services.
The disruption is not expected to last more than 60 seconds and you may be required to login a second time.
A delay in receiving online acknowledgement to submissions made using HMRC or commercial software may be experienced during this period. Your acknowledgement will be sent once the service is restored. Please do not attempt to resubmit your submission.
HMRC apologise for any inconvenience this may cause.
