Introduction: relevance of an “office or employment” for tax and NIC purposes
Section 19(1)1 ICTA 1988/Part 2 ITEPA 2003
SS Contributions and Benefits Act 1992 and the SS (Categorisation of Earners) Regulations (SI 1978 No. 1689)The income of an individual who receives payments for services will normally be chargeable to Income Tax as trading income or as employment income.

The individual’s employment status will also determine liability to pay National Insurance contributions (NICs). The general rule is that a person engaged as an employee or office holder will be liable for Class 1 NICs. A person engaged on aself-employed basis will be liable for Class 2 and, normally, Class 4 NICs.
In the majority of cases status is decided on the same basis for both NICs and tax. There are some exceptions though, which are covered at ESM4000onwards.
