I paid a tiny amount of NI on my school holiday job aged 14 - 16. I went into fulltime work at 16 till I had a year off with my first child when I was 28. I worked part-time employed and self-employed till my eldest child was 12. The self-employment was almost fulltime but a lot of it was done at home in the evenings. When daughter was 12 I worked fulltime plus self-employed for the rest of my working life, paying Class 1, 2 and 4 NI (the latter being essentially just an additional tax on income). There were only a couple of years when I paid tax at 40%. At nearly 72 I am still doing some self-employed work, though not paying NI on it since drawing the state pension at age 63.
My husband didn't start work till he was almost 23. He is 5 years older than me, went to Uni, and retired at the state pension age of 65. Despite doing some self-employed work as well, he never had to pay Class 2 NI.
Despite extensive research, including getting my NI record, I have never worked out why my SP is over £20 a week less than his - both Legacy SPs - when I paid contributions for 5 years more than him and technically had Home Responsibilities Protection for 18 years.
Of course, the New State Pension is now streets ahead of mine despite all that I paid in NI for 47 years. Summat ain't right.
Fortunately I have an Occupational Pension as well as two small private pensions as well, and am not complaining about my overall income - just the unfairness of it all.
He would not have paid Class 2 NI if hew was employed. Employees have Class 1 NIC deducted from their salaries. class 2 is what used to be known as the self employed stamp.
Class 2 is not paid by anyone with profits less than £6515 although they can chose to pay it voluntarily. Class 4 is paid on profits over £12570 at 9.73%. (the rate reduces to 2.73% on profits over £50270)
