I have never updated my details with HMRC

Hi, I have discovered today that I should have contacted HMRC when my name changed due to marriage and also my changes of address. I worked for the same employer for nearly 40 years and I have since taken early retirement. I have an NI Number but I think it is associated with my maiden name. I got married 23 years ago. I have also had two changes of address. I have tried to update my details online but get caught in a loop of trying to prove my identity, as my NI number is still associated with my maiden name and presumably the house I was born in. I can't remember the exact time I first changed address as I was in my 20s when I left home, I'm now 60. Can you advise me as to the best course of action please? I obviously need to link my work activity/NI contributions/NI Number to my current name and address. Thank you.

Hi,
Unfortunately, it is not possible to check individual tax records through this forum, if you have a question which relates to your personal tax situation or tax code please contact our helpline:

On this page you will also see a link to Personal tax account: sign in or set up which may be the quickest way to review information relating to pay and tax history, tax codes and how to change them. 
Thank you.
