I have a client who does his own annual VAT returns, so no HMRC functionality to deal with it until October. However, bombarded by 'get ready' messages, he managed to miss the 'don't sign up too early' messages and signed up for his year-ended March 2019 VAT return.
He seems to be stuck in limbo (as per the warnings). Is there a way of unsticking him and getting the return submitted and the payments on account restarted? HMRC Digital believe 'another business area' will be sorting these out but are unable to provide a time frame.
