Since 1968 I have never paid anything but self employed stamps, in fact at the start you did actually go to the post office and buy a stamp and stick it on a card for the year ,you could buy as many as you wanted at any time to complete your card.
Obviously it's moved on now but it still works the same, it's just like any other insurance scheme but nothing to do with any other tax.
Edit and it provides your full pension

Yeah I think that's the best approach
