Apologies in advance for the long note...
My child turned 12 six months ago so I have no more National Insurance credit towards my state pension. I had been thinking of paying voluntary contributions (Class 3) until one day I rang HMRC and was told I could pay Class 2 contributions instead IF I register myself as self-employed.
I had been SAHM since my child was born but have started making tiny money from ad-hoc teaching since last spring. I earn less than £1000 annually currently so I was told I wouldn't need to register as self-employed but if I do I would be qualified for Class 2.
Class 2 NICs are currently £156 annually, whereas Class 3 NICs are £780. It looks like I should register as self-employed for the smaller amount of contributions. However, I assume there would be something else I should start paying if I become self-employed officially like a tax.
I am hoping to be employed in a couple of years time but I'm afraid not for a good while for several personal reasons. In the meantime, I am going to continue my teaching job as a freelancer and hopefully, manage to increase my annual earnings, then registering as self-employed would happen at some point or could be employed before then.
So..., my questions are;
Should I register as self-employed now even though I earn so little so that I could be qualified to pay less contributions (Class 2)? Or should I choose to pay nearly 5 times more than Class 2 (Class 3) until I start earning more from my freelance teaching and/or until I get employed? Which one would I end up paying more???
I am sorry if my questions are a bit off. I have no clue but no intention to break the law! Appreciate any advice...
