What is a National Insurance Number?

Posted in

The National Insurance number is an unique and individual number through which the government identifies your national insurance and tax contributions. You need a NI number in order to apply for benefits and to prove your eligibility to certain services such as the Health Service.

Most workers in the UK pay national insurance. National Insurance (NI) contributions are what you pay towards a UK State pension and State benefits to help you if you lose your job or if you are too ill to work.

If you are employed, your employer will deduct the NI directly from your pay. If you are self-employed it is up to you to pay NI direct to the UK government department.
