Hi there, @info2366. The error message you've seen means that your link between QuickBooks and HMRC is no longer active. Connections automatically expire every 18 months to maintain security.

 

To resolve this, you need to reauthorise the linkage. Here's how

 

  1. Go to the Gear icon and select Account and Settings.
  2. Move to the Advanced section and edit the Making Tax Digital section. Then, turn off MTD.
  3. After that, reconnect QuickBooks to HMRC using the correct MTD credentials.
