I have been unable to log into my personal tax account. When I try i get the message saying password is incorrect even though i know it is correct as regularly log in. I then tried to reset password and had the following message 'You cannot reset your password online Contact HMRC to get help.' I have contacted HMRC and they have said they will investigate and have given me a case reference but are not getting back to me. Its very frustrating as i would like to file my self assessment and check my corporation tax account, neither of which i can do. Has anyone else had this issue and how do you resolve it?
