Also the same, nearly all Self employed people I know had there payment sent out on 18th April and received it in bank yesterday. Some had only submitted there returns last week. Self assessment have told me today that if it is still showing as pending as of today on a return sent on 6th April, it will of been selected for additional security check. When I asked what kind of security checks are taking place they couldnt tell me, and I asked if i need to provide any information and they couldnt answer that either. hours of being on hold on phone calls and online web chats yet no one seems to be able to answer anything nor knows anything.
