Introduction
National Insurance Contributions (NICs) are payments made by individuals with earned income in the UK that contribute to the National Insurance Fund. The fund finances various state benefits such as retirement pensions, jobseeker’s allowance, widow’s benefits, incapacity benefit, and maternity benefits.
Historical Context
The concept of National Insurance in the UK can be traced back to 1911 when it was introduced under the National Insurance Act. It originally covered health insurance for workers and unemployment benefits. Over time, it expanded to include a wider range of benefits and became a crucial part of the social security system.

There are six different classes of National Insurance contributions:
-
Class 1 Contributions:
- Primary Contributions: Paid by employees.
- Secondary Contributions: Paid by employers.
- Rates depend on earnings and membership in contracted-out occupational pension schemes.
-
Class 2 Contributions:
- Flat-rate contribution by self-employed (now abolished).
-
Class 3 Contributions:
- Voluntary contributions to maintain contribution records.
-
Class 4 Contributions:
- Paid by self-employed individuals based on their annual income.
-
Class 1A Contributions:

Mathematical Models/Formulas
- Class 1 Primary Contributions:
$$ NIC = \begin{cases} 12\% \times \text{earnings between £155 and £827} \\ 2\% \times \text{earnings above £827} \end{cases} $$
- Class 4 Contributions:
$$ NIC = \begin{cases} 9\% \times (\text{annual earnings} - £8,060) \text{ if earnings } \leq £43,000 \\ + 2\% \times (\text{annual earnings} - £43,000) \text{ if earnings } > £43,000 \end{cases} $$
