HM Revenue & Customs Online Services system upgrade postponed

We have decided to postpone this weekend's scheduled upgrade of our systems and we are sorry if this has caused you any inconvenience.

Whenever we undertake maintenance work we run rigorous tests beforehand. These checks were completed last night and we discovered that there was a problem and that part of the upgrade wouldn’t have been complete by Monday morning as previously announced.

This means that all our services will be running normally this weekend and we are working to choose a new date and approach that has the least impact on our customers.

The Service availability page will be updated accordingly shortly.
