Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether she has had recent discussions with HMRC on recent technical issues affecting the online self assessment process; and whether HMRC has made an assessment of the cause of those issues.

HMRC had two unrelated incidents during August impacting the online Self-Assessment service, one for 21 hours and one for 8 hours. As part of HMRC’s standard process, both incidents were resolved as quickly as possible and analysed in post incident reviews where we took learnings and put in place actions to avoid future incidents.
