Will I still need to file Annual Accounts and a Confirmation Statement whilst the company is in the process of dissolution?

In this time, and immediately after Companies House receives the application, you will not be required to file anything else to Companies House, i.e. a Confirmation Statement or Annual Accounts. Please note that HMRC will not be informed about the dissolution process. Thus, we strongly advise you to contact your Local Tax Office as you may still need to file your last company Tax Return.
