Being that time of the year I have representative numbers to hand.
My 'contracted out' NI contributions for the year are roughly:
Pers NI = £4.5k
Employers NI = £9k
Total = £13.5k
For someone on £30k, but not contracted out:
Pers NI = £2.7k
Employers NI = £3.1k
Total = £5.8k
Is it really the case that person with the lower personal and employers NI contributions will receive more state pension?
