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:

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. Class 1 National Insurance Rates

Anyone who is employed pays Class 1 National Insurance, the amount they pay is based on their earnings.  Here are the 2021/2022 Class 1 National Insurance Rates:

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:

  • Tax Year 2021/2022: Over £170 per week/£737 per month/£8,840 per year 13.8%

There is an additional level called the upper secondary threshold where the employer NI rate is 0% for certain employees under 21, apprentices under 25 and certain military veterans.

Upcoming changes to the secondary threshold have been announced as part of the Autumn Budget and include an increase of the employers’ NI rate payable to 15.05% from 13.8% from the tax year 2022/2023. That’s an increase of 1.25% in line with the new taxation for the NHS and social care. Read more about the Autumn Budget Changes.
