Examiners NICs query

Hi, for the first time, my only source of income for the last tax year has been from my work as an examiner for the exam board. In the past, I have always paid National Insurance contributions through my previous employment in a school. I understand that, as an eaminer, I am eligible to pay voluntary class 2 National Insurance contributions which I would like to do as I do not want gaps in my National Insurance. How do I go about arranging this? The tax return did not mention anything about paying this?

Hi Rachel Thatcher,

Please see the link below to the Gov.UK website.
Pay Class 2 National Insurance if you do not pay through Self Assessment
This explains that as an Examiner you will pay direct to HMRC and you will receive a bill every October, if you click the link Newly Self-employed Helpline
this will take you to How to call HMRC on 03002003500 to register to pay Voluntary Class 2.

Thank you
