I assume that my understanding of different Classes and contributions must be wrong:
I have been paying Class 3 Voluntary contributions for a couple of years after I stopped full time work as otherwise I would not be able to get a full pension - I have not been working and not looking for work. The contributions were about 8 pounds per week
I have recently signed on and have been looking for work - Jobseekers have been paying my NI contributions - don't know how much - I stopped paying the Class 3.
I am now going to be self-employed and will be paying Class 2 - at
2.20 pounds per week. I will also have to pay Class 4 at the end of the tax year - on 8% of any profit I have made.If I have not made any profit - because I haven't been getting the contracts I am looking for - it seems to me that I will pay less NI contributions overall
There must be something wrong with my understanding as otherwise it is pointless paying any Class 3; just pay Class 2 with zero under Class 4 as there was no profit (as you didn't do anything).
