  • RE: Cannot register for Self Assessment

    I am having the same issue - submit SA1 online to register for self assessment and get email responses saying "address provided does not match our records" despite it being the same address in my Personal Tax Account online AND the same exact address used to send me a new tax code. What a shambles. Have now eventually (after wanting to throw my phone out the window) got through to someone who said "I'll transfer you to self assessment and you can register over the phone". The self assessment person was not keen to do this and kept wanting me to post a SA1 instead as "would have to go through 2nd level security". I insisted and now might be registered? But no email confirmation or UTR appearing online or in HMRC app so not convinced. First time dealing with this and I'm shocked at how bad it is.
