I reckon Im received my NI Number inn 1956.
Today I wanted to create a personal tax account with HMRC. I handn't needed one previously because I used my tax agent account. (I retired at the end of 2024).
The HMRC asked for my NI number.
I read it straight off my last coding notice.
The website replied: We have no record etc.
I managed to sort it out but I had made no mistake..
I have had similar problems with banks this year. Sometimes their software updates caused havoc. It is unbelievable that they do not test adequately before releasing.
