HMRC are planning service downtime for MTD VAT during the following times to support security updates being released.

  • From 11.30pm on Saturday 8 June 2019 to 10.30am on Sunday 9 June 2019.
  • From 11.30pm on Saturday 15 June 2019 to 10.30am on Sunday 16 June 2019.

A further period of scheduled maintenance will take place on 17 June 2019 from 9am to 5pm (at the latest) on the VAT APIs and the Online Tax Account. This release will fix a known issue allowing customers with a numeric period key to view previously submitted returns and their obligations periods will be marked as fulfilled. Customers will still be able to sign up to the service during this time.

Software will receive a 500 service unavailable message during these times.
