I am in the process of starting book-keeping from home. I am AAT qualified and just wondered if I am able to do tax returns for all clients, be it soletraders or limited companies? I'm sure I was told whilst I was studying that with an AAT qualifiation you can only prepare tax returns for limited companies. I understand that I will have to register with HMRC complete tax returns for clients..... Please could someone shed some light for me!
