The scheme where people work and make monthly payments to the national assets pays of when one is unable to work. It is a state owned facility which is paid by everybody to avail the state benefits in future. The payments made in regard to avail the benefits are called the national insurance contributions which are made by the working people monthly. The government takes these allowances from people to give them the facilities such as pension and retirement benefits. You can get these benefits only if you have a certain record of your working life and even if you have not been working for a certain duration you need to explain them by showing solid reasons and logic, such as child care, sickness or taking care of the elderly or a patient at home. The contributions requirement is relaxed for women if they are married and they have to look after children and their homes.

National insurance number is given to the individuals making contributions in the scheme. The number is required when you go for a new job or when you want to apply for a claim from the government for certain benefits. The fulfillment of the claim will depend heavily on the contributions that you have made earlier in the past while you spent working. The number keeps a track of your contributions and then delivers the benefits in accordance with the record. The number is strictly confidential and for you own use and should not be used by anyone else. Everyone in UK receives the number when they reach the age of 16 as you need it before you can apply for any job or for starting your own work.

You have to pay national insurance if you are living in Great Britain or in Ireland if you are an immigrant you also need to pay the insurance unless you have immigrated from the European union countries in that case you need not pay for insurance if you are already paying for insurance in your own country. The insurance you pay is compared with the amount of your earnings. If you earn less then you pay less of insurance and in the pension age you get a lesser amount of pension. On the other hand if you are earning a heavy amount you pay more insurance and in return you get more insurance benefits in your pension age.

The national insurance for self employed people who are earning less than the limit set for contributing in insurance do not have to pay insurance and you are exempted from it. You only have to contribute till a certain age that may be 60 or 65 and then you get a certificate from the government you can show to your employer so your insurance is not cut from your pay.

The national insurance contributions also help the widows and people with disabilities to benefit from the contributions made by your late husband or your care takers during their working life. The retirement pension can also be used by your civil partner, wife or your husband in case of your death. The contribution can go a long way and benefit your children also in your absence. For women who are divorced are also given relaxations in the contribution policies and the pension they receive later in life. In case if you are not sure about the contributions your husband or your care taker has done you can always get them checked from the legal documents to make sure that you are receiving the right amount of benefits from the government authorities.
