Class 1 Thresholds

The level of income at which employers and employees become liable to pay N.I. contributions.

Class 2 and Class 4 Contributions

These two classes are specifically for self-employed people; which class you fall under will depend on the level of profits you make in each tax year.

Class 3 National Insurance

This is a voluntary class and is in place to allow individuals to maintain contributions during gaps in their employment history when they are not claiming benefits. If, for example, you decided to travel overseas for a period of time, you could elect to pay Class 3 contributions to ensure that you do not miss out on any benefits in the future.

Why Is National Insurance Important?

The reason it is so important to stay up to date with your contributions and to rectify any problems at the earliest possible opportunity is because there are a number of key benefits that are linked to your N.I. payments.

  • Basic State Pension – This is the basic amount to which every UK citizen is entitled after retiring, assuming they have kept their N.I. contributions up to date. This is obviously a very important benefit as without it, you could struggle to look after yourself in your old age.
  • Additional State Pension – The contributions you made while employed may also have gone toward an additional pension, which is basically an extra amount paid over and above the basic pension. During any periods of time when you were self-employed, unemployed, or engaged in full-time training, the contributions you made would not have gone towards the additional pension. This is because the rate of contributions for people in these categories is lower than for those in full-time employment. For an in-depth explanation of how this benefit is calculated, you can of course call the National Insurance Contact Number and ask for further details.
  • New State Pension – For those who are yet to retire, the above two pensions are going to be replaced by this one: a single state pension that is based on the N.I. contributions you have made throughout your life. It is designed to be simpler and easier to understand but of course, this may not always be the case. For those with more complicated employment histories that may include periods of unemployment, self-employment, or times when you were simply otherwise engaged, it is recommended you call the National Insurance Number UK to ascertain your position regarding future pension payments.
  • Jobseeker’s Allowance – If you are out of work for any length of time, you may qualify for contribution-based jobseeker’s allowance, i.e. unemployment benefits that are based on the National Insurance contributions you have paid over the years.
  • Employment and Support Allowance – This contribution-based benefit is designed to help those who are unable to work due to sickness or disability. Again, it is related to the contributions that you have made during your working life.
  • Bereavement Allowance – If your spouse dies when you are over 45 but under the state retirement age, it may be possible for you to claim bereavement allowance for up to a year. The amount you are entitled to will depend on the level of your late husband or wife’s National Insurance contributions and how old you are when they pass away.
  • Maternity Allowance – Women who do not qualify for Statutory Maternity Pay may be able to claim this benefit instead. Self-employed mothers-to-be who are paying Class 2 N.I. contributions, for example, may apply for Maternity Allowance. The amount received will depend on the level of N.I. contributions that have been made.

Resolving Problems with Your Contributions

As you can see from the above list of benefits, there are a number of very good reasons that you should tackle any problems that arise with your N.I. contributions as soon as you become aware of them

If you believe that you have not been fully credited for the payments you have made, you can speak to a member of the National Insurance complaints team by calling the number above.

We hope that the information on this page has proved to be useful to you and that you are able to quickly resolve any problems you may have.
