National Insurance Helpline (NIC)

What is National Insurance in the United Kingdom? NI is a system of compulsory payments paid by employers, employees, and other workers.


Paying National Insurance Contributions helps to provide state funds.

The revenue that it produces benefits those who are sick, unemployed, or have retired from the workforce.

Most employees pay National Insurance (NI) voluntary contributions. They are usually abbreviated to NICs.

Paying National Insurance helps to secure your entitlement for claiming certain benefits. As a rule, NIC payments start from when you reach the age of 16.

NI payments also help to assure you get the State Pension in later life. That is providing you have paid enough NICs to qualify.

National Insurance Contributions can be paid by you, or they can be credited to you. These are a part of the UK taxation laws that take place each tax year. The amount of contributions or credits that you have accumulated shows up on your National Insurance record.
