What is National Insurance?

Workers who earn over a certain amount are required to pay National Insurance payments from their salaries. These payments contribute towards certain state benefits given to those in need. At first, National Insurance was paid towards that were unemployed or sick but later extended to those that are retired and have a pension, as well as other benefits. The self-employed also contribute towards National Insurance payments, usually by a fixed weekly or monthly payment. National Insurance is paid through the PAYE system the same way as income tax and student loan repayments. National Insurance was first introduced in 1911 in the form of the National Insurance Act. The act was the first amendment to introduce the idea of paying contributions to benefits by the employed. Contributions are now split up into three classes. Class 1 contributions are paid by employers and employees. The employee’s contributions are known as the primary contribution and the employer’s as the secondary. If you are self-employed, you will pay class 2 and class 4 National Insurance contributions. For more information about National Insurance classes and what their contributions mean, please call the National Insurance Helpline.

National Insurance Number UK

Paying National Insurance contributions is the law in the UK and if you fall into the contribution category as an employee the amount that you owe will be deducted from your salary. If you are aged sixteen or over, are an employee earning over £155 per week or are self-employed and are making a profit of over £5, 965 annually then you will be expected to make National Insurance contributions. Before you can pay your National Insurance contributions you need to be issued with a National Insurance number. You will also need a National Insurance number to begin any kind of work in the UK. Every person in the UK has a National Insurance Number that is unique to them and the number ensures that your tax and National Insurance contributions are recorded against your name only. Your National Insurance number will be made up of a mixture of numbers and letters and will not change. If you are unsure of your National Insurance number you will find it on things such as any p60’s that you have received or your monthly pay slip. You can also log into your personal tax account (if you have one) and find your National Insurance number there. If you have forgotten any log in details please call the helpline. If you don’t currently have a National Insurance Number, was never sent one when you turned sixteen or have lost is, you can re-apply on the Government website, or find it if you have lost it. Please call the helpline if you require assistance in doing this. There are many uses for your National Insurance number, and certain people and organisations will need to know what your National Insurance number is. These include; HMRC, your employer, the DWP if you claim state benefits, if you claim housing benefit then you will need to give your National Insurance number to your local council. Your National Insurance number will also be used on the electoral role and you will need it to register to vote. If you plan to open an ISA or take out a student loan, these companies will also need to know your National Insurance number. Keep your National Insurance number safe in case it is used in identity fraud – if you notice anything suspicious, please call the helpline.

National Insurance ContributionsNational insurance payments

National Insurance contributions vary depending on how much you earn. Your job title will put you into a specific ‘class’, which determines the amount of your contribution. If you earn over £155 per week and are under state pension age then you will fall into class 1 and have your contributions deducted by your employer. If you are self-employed, you will fall into class 2. You are not legally required to pay National Insurance if your earnings are not over £5, 965 a year, but if you would like to make voluntary contributions to stop gaps on your National Insurance record, then you can do so. Making voluntary National Insurance contributions will put you in class 3. Class 4 is for the self-employed earning over £8, 060 a year themselves.

Apply for a National Insurance Number

If you do not have a National Insurance Number, you will need to apply for one on the Government website. You may not have a National Insurance number if you are only just moving to the UK, but instead, you will have a number printed on the back of your BRP (biometric residence permit) which can be used. If you do have this, you don’t need to apply for a National Insurance number. If you do not have this but do have the right to work or study in the UK, you will need to apply for your National Insurance number. You can still start work if your number is in the process of being generated. Applying for a National Insurance number may require you to attend an interview. If this is the case, you will be written to by Job Centre Plus. In the interview you will mostly be asked about your circumstances and why you need a National Insurance number. You will need to bring documents to the interview to prove your identity eg a driving licence or a passport, a resident permit or a birth certificate. All of this will be stated on the letter you receive. Once the interview is over, you will be told how long you can expect to wait to receive your National Insurance Number.Please call the helpline if you did not receive a National Insurance number when you turned 16.
