ERROR: 422-117-11 We can't authorise your client

Resolve error 422-117-11 when an existing HMRC connection stops working in AccountsPrep.

Written by Oliver Cook

This error can appear if HMRC revokes the authorisation token or your client is no longer enrolled in MTD for Income Tax.

  1. Go to Settings, then Income Tax.

  2. Disconnect the existing HMRC connection.

  3. Reconnect using the standard MTD authorisation process.

  4. Check your client's MTD enrolment status through your HMRC Agent Services Account.

If your client isn't enrolled, they'll need to resolve their enrolment before you can reconnect.
