Class 2 National Insurance contributions: general information: small earnings from subsidiary self-employment: administrative concession
A person who was in concurrent Class 1 and Class 2 employment previously did not need to pay Class 2 NICs or apply for SEE (NIM21000) if:
- the earnings from Class 1 employment were at or above the Lower Earnings Limit (see NIM01005); and
- the net earnings from self-employment were expected to be £1,300 or less in the tax year
This was a concession and was not written into legislation. Following the House of Lord’s decision in R v IRC, ex parte Wilkinson  UKHL 30, HMRC reviewed administrative concessions and this one was removed. Any person who is self-employed must register as such, and if their relevant profits are below the small profits threshold they will not be liable for Class 2 NICs, but can pay voluntarily if they wish to do so.
