National insurance is a scheme where people in work make payments towards benefits. The payments are called national insurance contributions and certain benefits are only payable if you meet the national insurance contribution conditions. National insurance contributions also go towards the costs of the National Health Service. The national insurance scheme is administered by HM Revenue and Customs (HMRC).
If you claim a benefit or tax credit, you will need a national insurance number. This applies even if it is not a benefit which depends on national insurance contributions. You will also need to supply your national insurance number in other circumstances, for example, when you get a new job.
