I seem to have a massive shortfall in my state pension according to hmrc😞 2,500 four years worth. I though I was covered by hrp but obviously wasn't. Eek I'm just going to have to pay this at some point. I thought I had paid enough in, as seem to remember going to post office an paying in to cover my Ni. Really confusing. I won't get my full pension if I don't pay it will I? Really annoying as I worked intermittently but obviously with child care duties didn't earn enough, I would of been better signing on. Why doesn't anyone tell you this stuff.
