Hi all! \r\n\r\nI have a keen problem. I want to help my brother with his self assessment and is the first time for me when I have to deal with HMRC website to send the online tax return. He previously had an accountant, but now, knowing how to calculate his taxes I want to submit it, only the HMRC website is difficult to deal with. \r\n\r\nMy question is, do I/him have/has to ask the ID and the password of his online HMRC account from his previous accountant to log in or do I have to create a new one even if he has an HMRC account?\r\n\r\nPlease, help me, because I really need your advice. Thank you in advance!\r\n\r\nHave a happy New Year!
