1. What is National Insurance?
National Insurance is a type of tax where UK workers (whether employed or self-employed) pay into a ‘pot’ which then entitles them to claim certain state benefits such as:
- Unemployment benefits
- Statutory sick pay
- Maternity pay
- Self-employed maternity allowance
- State pension
- NHS
It is also referred to as ‘NI’ (national insurance) or Social Security and is payable by UK workers 16 and over. Individuals stop paying it once they reach the State Pension Age. The government track how much national insurance a person has contributed by their national insurance number.
There are 4 different types of NI classes and the type payable depends on status:
- Class 1 paid by employees automatically deducted through their payslips;
- Class 1a paid by employers on their employees gross salary and benefits in kind;
- The Class 2 paid by self-employed individuals on their taxable business profits;
- Class 3 voluntary contributions to fill or avoid gaps in national insurance records;
- Class 4 paid by self-employed individuals on their taxable business profits (this is in addition to class 2).

2.1 The Lower Earnings Limit
The Lower Earnings Limit (LEL) is the amount an individual can earn without paying national insurance, but without suffering gaps on their national insurance record so keeping their entitlement to claim state benefits.
3. Class 1a Employer National Insurance Contribution Rates
Employers pay class 1a national insurance for anyone they employ on their payroll, based on gross salaries that exceed the secondary threshold. The rates for the recent tax years are:
