I studied for a MSc then I went back as a mature student and did a PhD. So I was a full time student for over a decade in total and didn’t pay NI contributions during those years. I have 25 years left until retirement age and I need another 19 years contributions to get full state pension. I’m currently a SAHM, I hope this will change when my youngest starts school.
If you were me, would you start back-paying NI for missed years at this point? I have 5 years (while I was studying for my PhD) which I can back-pay if I want to. I don’t have a private pension and I’m not likely to be able to afford to pay into one, so I really need my full state pension.
