Planned system outage - 12 September 2026 | Our online services including myIR, self service phone lines and gateway services will be unavailable on Saturday 12 September, 2026 from 1pm to approximately 10.30pm while we complete a planned system update. We apologise for any inconvenience this may cause.

As part of the final stage of the transformation our focus shifted from delivery to transition and how the organisation would work in future. There were 3 main areas of focus:

  1. Supporting the transition of knowledge, practices, and processes from the programme back to the organisation, to ensure we were set up to deliver future changes in the tax and social policy landscape.
  2. Optimising and updating all our heritage business technology.
  3. Decommissioning old applications and either archiving or ethically destroying the data they contained to minimise risk.

The work was complete by the close out of the business transformation programme in June 2022.
